Chapter 964 Rain Curtain, is there a mole in the inner city? (6000 words long chapter)

Old Dong followed Li Yu silently. The uncle and others next to him looked at him incomprehensibly, as if they were observing his reaction.

Lao Dong secretly thought: Where does the electricity at Da Zhangshu Base come from? It is so mysterious.

At the same time, the curiosity in my heart became even stronger, as if my heart was scratched by a cat, itching terribly.

Li Yu walked to the door leading to the zombie generator hall, and then slowly opened the door.

Squeak——

Because Li Yu was in front and Li Yu was taller, the view inside was blocked.

But there is light inside and it looks very bright.

Although the zombie generator has stopped working, the electricity generated previously has been stored in the battery. When the zombie generator stopped working, the battery was automatically activated.

Li Yu leaned forward, gave up a position, and stretched out his hand in a please gesture.

hiss!

Old Dong gasped, his eyes a little frightened.

Then he took a few steps back.

Zombies, the whole first floor is full of zombies, there are at least hundreds of them at a glance.

Moreover, these zombies are still alive and walking on the machine at this time.

"This" Old Dong couldn't say the complete words for a while.

The shock in his eyes was clearly evident.

But soon, he discovered that these zombies were welded to death on the machine and could not get off at all, and their entire heads were welded to their heads with an iron shield.

No danger!

Then he plucked up the courage to get closer and observe.

As expected of an electricity expert, he figured out the operating logic of the zombie generator in just a few minutes.

Tsk-tsk exclaimed: "Good! How good! Generate electricity through zombies, use the kinetic energy of walking zombies to convert into mechanical energy, and then convert the mechanical energy into electrical energy.

The rotation of the chain drives the generator to generate alternating current, which increases the voltage through the transformer and is transmitted to the box-type substation through cables.

It's really amazing. Who came up with this idea? How wonderful. "

He approached these zombie generators. The zombies on the machines noticed his approach, became extremely excited, and wanted to bite Lao Dong.

However, his arm was cut off, his entire leg was welded to the machine with a steel plate, and his head was also welded by an iron cage. This made the zombie tightly restricted to the machine and unable to get close to Old Dong. On the contrary, because the walking speed becomes faster, the rotation of the wheel chain behind is accelerated.

It was just that due to a malfunction, it was not converted into electrical energy smoothly.

Li Yu on the side saw Lao Dong squatting next to the zombie generator for inspection, and explained: "He Bing and Zhou Ran accidentally tried to make it. We named this machine the zombie generator."

"This is the main source of electricity for the Da Zhangshu base."

Old Dong stood up and praised: "Others were scared to death when they saw zombies, but no one thought that they could use the characteristics of zombies to generate electricity. They are geniuses!"

Li Yu suddenly approached and asked, "Continue to check and see if it can be repaired."

At this moment, a cry of surprise came from behind.

"Holy shit, this is okay."

Li Yu turned around and saw Tianshu brought in by He Bing.

He stared at the zombie generator inside with wide eyes.

He Bing on the side said: "This is one of the sources of power energy in the Da Zhangshu Base. It must be kept secret."

Seeing Tianshu come in, Li Yu said to Tianshu and Lao Dong:

"This is the core secret of Da Zhangshu Base. Let me remind you that you don't know anything outside this house. Do you understand?"

The tone was obviously very calm, but both Lao Dong and Tian Shu felt a sharp murderous aura coming from them.

They knew very well what kind of person Li Yu was.

Li Yu has said this at this time, which means that if they leak it out, the consequences will be dire!

Old Dong shook his head and quickly expressed his loyalty:

"I understand that I don't know anything after I go out, and I will never tell anyone what I saw today."

"Yes, yes, Mr. Li trusted us by letting us in. How dare we leak it?" Tian Shu, who was next to him, also said quickly.

Based on their brief observation, they roughly understood the principle. In fact, the principle is very simple, and it is not that troublesome to make.

The point is this bold idea.

How could ordinary people think of using zombies to generate electricity before they could avoid them?

When Li Yu heard the two people's answers, he nodded slightly and said to them: "You guys see how to fix it. He Bing, Zhou Ran, tell them about the situation."

He Bing came over, pointed to a broken wire and said:

"The situation is like this. Due to the thunderstorm outside, the wires were short-circuited. In addition, all the zombie generators were connected in series, which caused all the generators to stop operating. In addition."

With He Bing's explanation and the inspections of Lao Dong and Tian Shu, they slowly figured out the problem.

"It seems that there are three problems now. 1. The wires are short-circuited and aging. This can be solved by replacing the wires.

2. The lightning protection resistor device just mentioned by He Bing needs to be buried underground to avoid lightning damage to the power grid, otherwise it will still be prone to short circuit.

3. Series connection problem. Once a certain zombie generator fails, other zombie generators will also have problems due to the series connection. It is recommended to use parallel connection. "

He Bing next to him nodded and said:

"Yes, we are also considering these three problems, so we need your support to help solve these problems."

Tianshu thought for a while and said:

"In fact, there is another hidden danger. The box-type substation transmits the electric energy after the voltage is increased to the collector line. The current capacity of the centralized line is not enough, and it is easy to cause problems later. It is necessary to replace cables with thicker conductivity and stronger conductivity. .

Moreover, aluminum’s electrical conductivity is second only to copper, its electrical conductivity is only two-thirds of copper, but its density is only one-third of copper, and copper is denser than aluminum.”

Li Yu quickly asked: "Do you have this cable material?"

Li Hang, who was next to him, said, "Yes, just a while ago, the Fifth Satellite City collected a lot of copper core cables. There are a lot of them and they can be used."

Speaking of this, Li Yu had some impressions.

It seems that it was Lao Huang and his team who discovered a cable factory buried in the ruins. Later, due to the relatively high points exchanged with the Da Zhangshu Base, a craze for collecting cables arose among many cooperators.

The old Dong thought for a while and asked: "Is saving electricity mainly through batteries?"

Zhou Ran nodded and said: "Yes, currently it is mainly stored through batteries. Some of the electricity generated by the zombie generator is supplied to the Da Zhangshu Base for use, and the other part is used for electricity storage."

Old Dong touched his Mediterranean hair and asked: "What type of battery did you use?"

Zhou Ran replied:

"There is no need to worry about this. We all use common battery energy storage technologies, including lead-acid batteries, lithium-ion batteries, and sodium-sulfur batteries. These battery systems can store a large amount of electrical energy, release it according to demand, and provide continuous and stable power output.”

Old Dong nodded and continued: "It's good, but"

Then he was about to continue talking, but he was afraid of hurting Zhou Ran, He Bing and the others, so he suddenly stopped.

When He Bing saw this, he said bluntly: "Just say that you are an expert in power systems. Lao Zhou and I are both mechanical."

"Finished." Li Yu said lightly.

Hearing Li Yu speak, Old Dong continued what he had just left unfinished: "

It’s just that the energy storage of a single battery is still somewhat lacking.

There are generally two types of power storage technologies: 1. Battery energy storage: Batteries are used to store the electric energy generated by the wind power generation system.

2. Hydrogen storage technology: Use electrolyzed water to convert the electric energy generated by the wind power generation system into hydrogen, and then store the hydrogen.

When needed, the stored hydrogen can be converted back into electricity via fuel cells. Hydrogen storage technology can provide long-term energy storage and rapid release capabilities.

Moreover, fuel cells have high energy conversion rates and low noise.

Therefore, I think there are two ways to ensure more stability. "

Then Lao Dong talked endlessly and talked a lot. It was obvious that he was in his professional field. Many professional terms popped out of his mouth, and Li Yu couldn't understand it.

But he didn't interrupt.

Because he saw He Bing, Zhou Ran, Li Hang and the others listening carefully.

As they talked, He Bing and the others also intervened in the conversation. As they chatted, their expressions became excited.

Li Yu looked at the time. Ten minutes had passed since Old Dong and the others came in, and the time had already reached two-thirty in the morning.

So he said: "Let me say a few words."

Everyone stopped the discussion and looked at Li Yu.

"The first question is, how long will it take to repair the zombie generator? The second question is, how long can the power stored in the current battery last?"

Li Yu asked these two questions, and everyone present fell silent after hearing them.

He Bing thought for a while and said to Zhou Ran and others: "Let's allocate tasks. I will be responsible for the short circuit problem and you will be responsible for it. Old Dong, how long will it take for you to solve the series connection problem and the battery storage problem together?"

Zhou Ran said: "It will take at least 10 hours."

The old Dong made an estimate and said: "3 days. If someone comes to help me, it can be faster."

Li Hang quickly said: "I can help."

"I can do that too." Both Lao Luo and Li Zhengping raised their hands.

After hearing what they said, He Bing said to Li Yu:

"It can return to normal in half a day. Then we just discussed that the current power system needs to be upgraded. It will take about three days, but this will not affect the zombie generator's power generation."

"In addition, with the electricity we currently have saved, plus other wind power generation, we can last for two months."

Hearing this, Li Yu nodded with satisfaction.

Putting aside the zombie generator, in fact, based on the coal, charcoal, and oil currently stored in the Da Zhangshu base, based on the current daily electricity demand, it can last for two years.

But these things are currently non-renewable energy sources. As combat readiness materials for the Da Zhangshu Base, they should not be used unless necessary.

Moreover, the oil inside has other uses, making it even less likely to be used to generate electricity.

"Okay, then I will give you three days. During these three days, you can go to Li Hang to get all the materials and equipment you need. Li Hang, you go help them solve it."

Li Hang nodded and said, "Okay, brother."

Li Yu looked at Lao Dong and others, and finally said: "You guys work hard and don't leave here for the next two days. I will send someone to notify your family."

Lao Dong and others quickly said: "Understood."

After saying that, Li Yu walked outside.

Also accompanying me was my uncle.

The uncle and Li Yu came to the outside of the building. The eaves above blocked the heavy rain, but there was still rainwater drifting over.

"Where is your second uncle? Why didn't he come?" asked the uncle.

Li Yu squeezed the rainwater from his clothes and said, "He was sleeping. He was too busy during the day, so I didn't wake him up."

"Well, Xiaoyu, then I'm going back to the duty room. You should go back and rest early. Lao Luo and the others are here. He will tell you if anything happens. You don't need to come then. I'll just come over and solve it." said.

Li Yu nodded and watched his uncle walking towards the night sky holding an umbrella.

Although the street lights are bright, they cannot shine too far in the rain.

The rain was blurry, and the light was blocked by the rain, making it look like a hat.

My whole body was wet and it was very uncomfortable to stick to my skin.

Just as he was about to go out from under the eaves and return to the inner city, he saw a figure walking towards him in the rain curtain.

Um?

There are very few people coming here in the Third Outer City. Under normal circumstances, you need approval to enter the Third Outer City.

Except for Li Yu, Second Uncle and others in the inner city, as well as planting staff such as Anya, everyone else must report in advance when they come in.

Could it be the second uncle? Li Yu guessed.

He couldn't see the figure clearly from a distance, and it wasn't until he got closer that he saw the figure.

"Dad, why are you here?" Li Yu asked in surprise.

The father in the rain was wearing a raincoat, but it seemed that he had been in the rain for a long time. Although the raincoat had a certain protective effect, it still made his clothes get wet a lot.

Li Hongyuan saw Li Yu and said breathlessly:

"I've been looking for you for a long time. I went to the duty room first, and then I met Haoxian and said you might be here."

"Dad, what are you doing to me? It's raining so heavily. Go back quickly. Don't get wet."

With that said, Li Yu took his father's arm and walked into the inner city.

Father Li quickly asked: "What happened? Where is Xiaohang? Is he here too?"

"He's helping inside. It's not a big deal. Let's go back first." Li Yu couldn't help but drag his father towards the inner city.

"Ah? Yes"

"let's go."

"What happened?"

"The zombie generator has a short circuit. I asked He Bing and the others to repair it. It's not a big problem and it can be repaired tomorrow."

"Okay." Li Hongyuan nodded, not insisting on going over to take a look, nor asking any more questions.

In the past, Li Hongyuan was a somewhat macho man and was very strict with Li Yu and Li Hang.

It's just that in the past three years, I don't know when he started to feel that he was getting old, and then he didn't have a tough attitude towards Li Yu, but started to listen to Li Yu's words.

Invisibly, he felt a little dependent on his son.

He is already over fifty years old. People often say that before the age of twenty, he depends on his father, after the age of twenty, he relies on himself, and after the age of fifty, he relies on his children.

He is no longer so domineering, but his son has become domineering.

As he thought about it, the corners of Li Hongyuan's mouth raised.

When they reached the inner city, Li Yu suddenly asked again: "Did mom ask you to come?"

Li Hongyuan nodded and said: "Well, I was sleeping soundly. You took off the quilt from me in the middle of the night. I said you could solve it. If you don't believe me, let me come and take a look."

Li Yu felt warm in his heart, and a smile appeared at the corner of his mouth.

He said: "It's okay, let's go, go back and take a nap early, I'm a little sleepy too."

The two of them were walking in the inner city in the rain. After walking a few steps, Li Yu suddenly saw a figure sneaking out of the residential area.

In the rain curtain, people's vision is very limited.

Li Hongyuan did not see the figure, and that person probably did not see Li Yu and the others.

It's just that after Li Yu was reborn, his five senses such as vision, smell, and touch have all become much stronger.

So he could see the existence of that figure.

Li Yu's heart moved and he said to his father: "Dad, you go back first. I just forgot that there is still something to deal with."

"Ah? What should I tell your mother?"

"I'm so old, can I still get lost?"

"Okay, okay."

Father Li nodded and walked towards the villa area.

Seeing his father walking into the villa area, Li Yu rushed towards the figure in the distance.

soon.

He caught up with the figure. Under the cover of the sound of rain, Li Yu's footsteps were not noticed by the person in front.

After walking in, Li Yu saw who this person was.

Thinking of some rumors in the base, and considering him running out in the middle of the night, he guessed who this person was.

"Where are you going?!" Li Yu approached the man and shouted less than thirty centimeters from his ear.

thump!

The man trembled all over, tripped over his left foot and fell into the rain.

Bang!

Two fruit cans fell out of an aluminum box, as well as a pink hair tie.

The man turned his head and looked behind him in shock.

Because he fell to the ground, his eyes were wet with rain and he couldn't open his eyes, and it was dark and he couldn't see clearly.

Boom!

A flash of lightning flashed across his face, and he saw a familiar face looking down at him.

"Mom!!"

"Mr. Li, you are going to scare people to death!!"

"Scared me to death! You really scared me to death."

The man shouted tremblingly, his legs were trembling and he couldn't stand up at all.

The eyes looking at Li Yu were full of resentment and grievance.

Especially when he saw the pink hairband in his aluminum box falling into the muddy water, he felt heartbroken, and his expression when he looked at Li Yu became even more resentful.

Li Yu understood everything when he saw the pink headband.

These two boxes of canned fruits must have been saved by himself because he was not willing to eat them when the base was distributing welfare.

It is well known in the Da Zhangshu base that there is a person who has a crush on Shen Xiaoxiao, but he never admits it, but every time he sees Shen Xiaoxiao, he blushes terribly.

Shen Xiaoxiao is also a straight girl.

So until now, the two people still have a subtle relationship.

Li Yu had a joking expression on his lips, deliberately trying to tease him.

So he said to the man sitting on the ground:

"Who told you to sneak around in the middle of the night without sleeping, or to run out in the middle of the rainy night? Tell me! Are you a traitor, carrying the secrets of the base and wanting to rebel?"

The man was stunned when he heard this, and quickly turned on the flashlight in his arms. He just didn't want to be seen, so he never turned on the flashlight, but he couldn't care about anything else at this time.

"Unjust" he let out a pig howl.

"I'm going to the outer city to meet people."

"Meeting whom?"

"."

"Hmph, leniency will be given if you confess, strict if you resist." Li Yu almost couldn't hold back his laughter after saying this.

"Shen Xiaoxiao."

"Huh? Why do you want to see her?"

"Ah, this is so embarrassing."

"Say, or I'll arrest you!" Li Yu suddenly said fiercely.

"I, I, I like her. I replaced this hair tie, and the cans were saved from welfare benefits."

"Oh, is it so?"

"Yes!" The man suddenly stopped shaking his legs and stood up.

"Then do you dare to tell her? Do you have the courage?"

"dare!"

"What if you don't dare?"

"Then I am a traitor!"

"Okay, let's go now." Li Yu said.

"Huh? Now? Ah?"

"Let's go." Li Yu pulled him up directly.

The two of them walked towards the outer city in the rain.

Halfway through, he came back to his senses and said to Li Yu with a somewhat resentful tone: "Mr. Li, were you kidding me just now?"

"Traitors are so timid and don't dare to face their own feelings. Why are you so cowardly?"

"I'm not!" screamed.

"You've lost your voice."

"."

Seeing that he was getting closer and closer to the outer city, the man was obviously not prepared.

He walked much slower and asked Li Yu: "Mr. Li, how can I confess to her?"

"Just tell me, I'll help you out. Don't worry, I'm here, she won't dare to hit you."

"Ah this."

"Weiguo, some love already exists without saying it. If you don't say it clearly, it will only leave regrets."

"I see."

"Um."

"Let's go."

"Isn't it too direct?"

"I'm sorry, can't I leave?"

Li Yu thrust his foot towards Zhou Weiguo's butt, leaving a muddy shoe mark.

Li Yu couldn't understand why Zhou Weiguo, the person in charge of the breeding farm, was so cowardly.

"What a mess! Hurry up!"

"Wow. Mr. Li, you are so cruel and powerful!" Zhou Weiguo was halfway through his words. When he saw Li Yu, he wanted to kick him a second time and gave a thumbs up.
