Chapter 513 No Hope

It was still dark, and there was a light rain in the sky.

The pattering rain drenched the raw materials placed on the open space.

The second uncle got up early and asked a few people to collect some things that couldn't get wet.

When Li Yu was sleeping in the middle of the night, he heard the patter of rain outside the window and got up quickly.

The wall of the second outer city has not yet been built, and the rainy season is coming soon. If the rain does not stop, the construction of the second outer city will be delayed for a long time.

The height of this second outer city was built according to the standard of 15 meters.

These days, I also took advantage of the time to build the bottom floor below, which is now nearly 13 meters long.

There are two meters left in the height.

Just because I have been busy, I haven't installed the gate yet.

Li Yu quickly stood up, put on his clothes and ran to the outer city.

At this time, seven or eight people were already there in the Second Outer City. They were moving some cement made yesterday into a shed that had been built.

Li Yu walked down from the wall, stepped forward to help, and then asked his second uncle to call He Chao and others to come over and help.

After He Chao and the others arrived, the transportation speed was much faster.

Then Li Yu looked at the empty door and said to Old Zhou who also came to help: "Uncle Zhou, is the door you made a few days ago finished?

It took almost a week to complete, and I haven’t seen it yet. Now it’s almost finished, right? "

The second outer city also needed a door, so the people were handed over to Lao Zhou, a former mechanical constructor, and Yang Tianlong to help.

Lao Zhou was also wearing loose clothes at this time. He must have just woken up and ran over in a hurry.

Lao Zhou nodded and said: "Mr. Li, the door has been finished. We used almost five tons of steel plates and embedded reinforced concrete in the middle. Then we used a hook pull ring to open and close the door. Through leverage, one person can You can open and close the door.

Are we going to install the door? "

Li Yu nodded and said: "It's time to install it. It's raining lightly now, and I don't know if it will rain more in the future. It's the rainy season again. This time, it may not stop."

Lao Zhou felt that what Li Yu said made sense.

Li Yu said to everyone: "Okay, let's install the gate directly."

Lao Zhou replied: "Okay, it just needs a forklift to move it. I will move it over with a forklift later."

Li Yu nodded.

Watching Lao Zhou and the others move the big iron gate over.

This gate is not that huge, only five meters wide and six meters high.

It can accommodate almost all truck models.

On the wall, the staff on duty who had been observing the situation outside the base suddenly shouted to them: "Zombies are coming in. Everyone, pay attention."

After saying that, he picked up the crossbow and shot at the zombies.

The gate has not been installed yet. If the zombies are allowed in, the second outer city will be filled with zombies.

So he told Li Tie and others around him to go up to the wall to support him and prevent a zombie from entering the outer city.

Under Li Yu's order, the people on the wall started killing the zombies outside the base.

Rumble~

God struck a thunderbolt.

The sound was so loud, it seemed like it was exploding right next to your ears.

Lightning landed in the forest not far from the base, and Li Yu and others turned their attention there.

After a while, they saw a thick white smoke rising from the mountain forest in the north. Within a minute, the white smoke disappeared.

Wow!

Lao Zhou drove over with the largest forklift in the base, and then parked the forklift at the edge of the Second Outer City.

Li Yu turned around and said to the approaching cannon: "Hurry up and drive the crane over to the inner city. It will be used to install the door later."

Cannon quickly ran back to the base.

This second outer city also has an urn city built. The area of ​​​​the urn city is similar to the previous two.

At present, the crane is relatively large. If you want to drive out of the base, you can only get out from the earliest urn city built.

The gate of the earliest urn city built was both high and wide enough to allow the crane to pass through.

By the time the crane arrived, Li Yu and the others had temporarily placed some door opening and closing machinery on the unfinished fence.

Now in the second outer city, although it is not completed yet, it is already more than ten meters long.

Thanks to Lao Zhou's settings, the door of the outer city switch can be opened in two ways, one is under the outer city, and the second is on the wall.

But if you want to open the door under the wall, you must use a key to open it.

Although this door is very simple to open, the settings for opening and closing the door are not simple.

This is why Lao Zhou spent a lot of effort to create such a door.

The crane came slowly and lifted the big iron door.

Immediately afterwards, He Chao drove a forklift and held up the large iron door to prevent it from falling down.

"Hurry up and install it." Li Yu said to Lao Zhou.

On the wall, Li Yu saw a large wave of nearly a hundred zombies coming this way.

There's something wrong with this. It just started raining and there are so many zombies here.

Perhaps it was because of the lightning not far away that the sound attracted some zombies.

Li Yu looked at Lao Zhou and the others who were struggling to install the gate, so he said to the people around him: "Be sure not to let a zombie enter the outer city. Lao Zhou and the others are still installing the gate below."

Lao Qin also came. He put down the crossbow in his hand and said to Li Yu: "Mr. Li, can I use a gun? I have a silencer. The crossbow is too slow."

Li Yu glanced at Lao Qin and said, "Okay, whatever works well, you can do it."

Then let him go to the duty room to get the gun by himself.

Everyone struggled to resist the zombies running from the woods.

The zombies among them are the same as before.

It's just that Li Yu and the others are more nervous now than before. In the past, it didn't matter if these zombies came over. After all, there was still a wall blocking them.

However, these zombies must not be allowed to enter the outer city now. Once they enter, Lao Zhou and the others will be in danger.

Bang bang bang bang~

On the wall of the second outer city, they squatted on the wall that had not yet been built and kept attacking the zombies.

Thanks to the high temperature yesterday, the outdoor temperature reached 30 degrees. In addition, since the end of the construction yesterday evening, it has been more than 12 hours since the watering.

The cement and concrete on the fence has dried up.

They kept firing their guns, killing the zombies that kept coming.

The rain is getting heavier.

Because of their haste, none of them carried raincoats.

So wet.

The wall of the Second Outer City has not been constructed yet, so naturally there is no protective fence in place.

At a height of more than ten meters, without any protective barriers, it is still a bit scary when viewed from above.

What's more, they have to keep shooting up here to stop the zombies from coming in.

Half an hour later.

Boom!

The big iron gate was finally installed, and He Chao tried to open it a little under the wall.

beep~

The big iron gate was slowly opened.

Then I tested it again and closed it.

Also runs normally.

After closing the big iron door, everyone breathed a sigh of relief.

Li Yu also felt relieved, then got down from the wall and came to the front of the big iron gate.

He hammered the big iron door with a gun.

Boom!

A dull sound came out.

The sound is very solid at first glance.

Immediately, Li Yu said to Ding Jiu: "Can we continue the construction on a rainy day?"

Ding Jiu stretched out his hand, felt the amount of rain, pondered for a while and said: "It is recommended not to, now is the rainy day, if the fence is built in the rainy day, the sealing must be done well.

But now that there are zombies outside, if we want to seal it well, we have to work outside the wall. This is too risky.

In short, everything is to let the wall dry as soon as possible.

Fortunately, the temperature was relatively high yesterday, otherwise the parts constructed yesterday would have been affected by the rainy weather, causing the hardness of the wall to decline. "

Hearing this conclusion, Li Yu was silent for a while.

So he said: "What if there is no large-scale construction? No more building up, just build some guardrails on the edge, and do a good job of waterproofing, is that okay?"

Ding Jiu said: "You can try it. It's not raining too much now, but if the weather is like this, it may take three or four days to dry. In addition, the built guardrails can no longer be wet."

Li Yu nodded and said, "Let's do this for now. Don't build higher for now. Let's finish the fence today."

Ding Jiu nodded and said yes.

Just as Li Yu was about to leave, he thought that there were still many zombies outside, so he said: "You construction workers, each of you has a rope tied around your waist, so don't accidentally fall down during construction."

Ding Jiu said: "Okay, I will ask everyone to be careful."

Li Yu was relieved.

Seeing He Chao, he also said: "Let the brothers on duty outside come back quickly, while the rain is not heavy yet, there are not so many zombies outside.

When it rains heavily, they won't be able to come back even if they want to.

In addition, you must also do a good job in protection. The protection of the second outer city here will be left to you. "

He Chao nodded quickly, expressing that he would take care of everything.

After explaining all this, Li Yu returned to the duty room at the main entrance from the Second Outer City.

Now that the wall is connected to the city, wherever they want to go, they can just walk through the wall.

The duty room at the main entrance is the largest, with a space of dozens of square meters.

It was full of guns and ammunition, as well as a light machine gun.

Li Yu sat in the duty room for a while, looking at the pictures on the screen, which were all camera pictures near the wall and outside the base.

In the picture, the drizzle is blurry, and some zombies are wandering in the rain.

Some zombies raised their heads and swallowed the rainwater, while others walked numbly.

But in this rain, all the hidden zombies came out.

It seems that in the rain, they are the masters of this planet.

In the base, the newly planted crops also swallow up precious rainwater and thrive.

Li Yu sat in the duty room for a while and then came to the cell where the gentle man Madi was imprisoned.

Outside the cell, Li Haoran was watching the rain falling from the sky in boredom.

Seeing Li Yu coming, Li Haoran quickly stood up from the stool and said to Li Yu: "Brother."

Li Yu nodded, looked at Li Haoran and said, "How is that person inside now?"

Li Haoran said: "I didn't speak the whole time. If I gave him food, I would eat it. If I didn't give it to him, I wouldn't make a fuss. I just wouldn't say a word. I asked him questions and didn't answer anything."

Li Yu thought for a while, opened the cell door and walked in.

The room was a little dark.

Bah!

Li Yu turned on a white woven lamp.

That Madi was sitting on a stool, his feet were cuffed with iron chains, and his hands were tied with silver handcuffs.

At this time, as Li Yu turned on the white weaving lamp, Ma Di stretched out his hands to cover the light in front of his eyes.

Li Yu pulled a stool and sat in front of this man.

The backrest of the stool is in front. Li Yu puts his hands on the backrest and sits on the stool.

Look at this man quietly.

The man also heard the sound of someone coming in, but he did not rush to open his eyes to see who was coming. Instead, he slowly waited for his eyeballs to adapt to the light, and then slowly took his hand off.

When Ma Di saw it was Li Yu, his eyes narrowed slightly, and the fear in his eyes disappeared in a flash.

Li Yu just sat in front of him, saying nothing, just looking at him.

"Do you know that there is a correlation between rain and zombies getting stronger?" Li Yu suddenly asked.

"Is it raining?" Maddie said.

Then prick up your ears and listen carefully to the sound.

Crackling

Rain dripped on the eaves, and outside the room, water on the eaves splashed on the steps.

"Down." Li Yu also said to him patiently.

"The formation of zombies originated from meteorites from outside. The rain falling from the sky must have some elements that we have not studied, which caused these zombies to change."

"Elements that have not been studied?" Li Yu asked.

"Yes, I actually studied the difference between rainwater and groundwater in the chemical plant before. Except for some explicit elements and some normal trace mineral elements in the ground, I didn't find any difference at all."

Li Yu asked again: "Then why did the green zombies appear? What did you do?"

Madi thought for a while, various thoughts flashed through his mind, and said: "Green zombies are because the pH value of the water is too high, which severely consumes carbon dioxide, and beneficial algae cannot reproduce.

But this is only the superficial reason for turning green. This is just a dominant feature and has no necessary connection with the zombie becoming stronger.

The experiments I did have nothing to do with this.

It's just that in the chemical plant, there was a chemical waste that was in disrepair for too long and was scrapped, and then flowed into the wastewater treatment tank.

Later, I studied the wastewater discharged from the chemical plant and compared the elements and microorganisms in rainwater. There was no pattern at all.

I have no clue at all. I have researched for a long time and can't find any correlation between them.

It’s totally meaningless and there’s no discovery. I’ve done many experiments and there’s no pattern at all.”

Li Yu listened carefully and said, "So, when we saw you, you collapsed?"

Maddie nodded and said, "Yes."
