Chapter 22 Upgrading the technology tree, comfort in the air-conditioned room

As Su Yi opened the technology tree list, densely packed technology projects were listed in front of Su Yi.

At the top of the list, it says [Experimental House Sequence], and below are various technological projects, such as: [Basic Power System], [Autonomous Water Resources System],

[Strengthening of basic defense measures], [Preliminary projects for improving living facilities], [Improving scientific research and exploration capabilities], [Agricultural automation system], [Medical aid station], [Air purification system], [Intelligent monitoring network], [Garbage Processing Center], [Central Air Conditioning Module]...

Su Yi was almost dazzled by the dense number of technological projects.

Even if you don't look at the detailed effects of these technology modules, if you just look at the names, you can imagine that if all these technology projects are illuminated, the shelter will definitely undergo earth-shaking changes!

"Let me see the price..."

Su Yi looked carefully and murmured: "1000 survival points for the power system, 1000 points for the independent water resources system, 300 points for the garbage treatment center... 800 points for the central air conditioning module?"

“Damn, they’re all so expensive!”

Su Yi took a breath. He looked at his only 800 survival points and couldn't help but smile bitterly.

"It seems that building a shelter is really a long way to go. This is only a level 1 experimental house, and there will probably be more expensive technology projects in the future."

Su Yi was thinking about how to use these 800 points to maximize profits.

"Central air conditioning is very important, but for now I can also use ice water to resist the heat; medical aid station? It's also good, but not the most necessary."

"...Well, let's light up the [Scientific Research and Exploration Ability Improvement] module first! It costs 500 points, but it is currently the most profitable technology project!"

Su Yi selected this project for detailed viewing.

[Scientific Research and Exploration Ability Improvement]: Spend 500 points to send engineers, scientists and other scientific research talents to conduct research, which takes 10 hours; after the research is successful, the income from shelter exploration can be increased by 10% and the research speed of technology tree projects can be increased by 100%. Ten out of ten.

Although these two 10% may not seem like much, if accumulated, the additional benefits will be very objective.

"Just choose this one!"

"There are still 300 points left. Do you want to keep them, or should you look at them again?"

Su Yi thought about it, and his eyes couldn't help but fall on the technology project of the [Garbage Treatment Center].

[Garbage Disposal Center]: It consumes 300 points and dispatches engineers, scientists and other scientific research talents to conduct research, which takes 12 hours; a fully automatic domestic waste treatment equipment is built in the shelter, which can harmlessly process all types of garbage.

"Exactly 300 points!"

Su Yi only hesitated slightly and finally chose to purchase the project.

There was no other way, he really couldn't stand the smelly feeling at home.

After the city water source was gone, even toilet flushing was no longer possible. A large amount of excrement had to be accumulated every day and then treated with smelly water that was about to go rancid.

Even if he does this, Su Yi still feels sorry for water resources.

Modern humans already have civilization, and it is naturally difficult for them to tolerate living in an unhygienic environment.

Excrement can breed bacteria and is also a major threat to human survival.

[The science and technology project has been selected, please send suitable talents to the scientific research room for research. 】

"Liya! Liya!"

Su Yi quickly called Li Ya back downstairs. Li Ya went upstairs and stuck her head out, asking doubtfully: "Boss, did you call me?"

"How are the defenses downstairs constructed?"

"It's almost there. In another half hour, the trap and gate reinforcement at the entrance will be completed."

Li Ya said with a smile: "Although this building is a bit old, the materials used are very strong. The original door was an iron door, which saves me the need for large-scale renovation."

"Well, let's take a good rest today when we're done. There's still a big project to do tomorrow."

Su Yi nodded and informed Li Ya of the research projects of the two science and technology projects.

When Li Ya heard this, her eyes lit up: "Boss, you don't have to wait until tomorrow, I can do it now!"

"Now?"

Su Yi glanced out the window, and it was already dark: "It's already after 11 o'clock in the evening, right? It's too late, so let's have a good rest."

Su Yi didn't want to squeeze his subordinates too much, but Li Ya's attitude was very firm: "No! Boss, I can study all night!"

"I promise to complete the task before tomorrow night! I can issue a military order!"

Li Ya was very eager, her beautiful eyes sparkling with enthusiasm for scientific and technological research.

Su Yi was helpless, but he didn't expect that Li Ya looked weak, but was actually a scientific madman.

"Sir, I also support Miss Li in conducting research now."

Jiang Xiaoci on the side suddenly spoke up and gave his opinion softly: "This is an extraordinary moment. Our lives depend on it. The sooner Miss Li can play her role, the better we can ensure everyone's safety."

"So, most of the time we can't pay too much attention to normal work and rest, but have to make adjustments according to local conditions."

Jiang Xiaoci said it tactfully, and Su Yi nodded in agreement: "Okay, that's it, it's just going to be hard work for Li Ya."

"It's okay, boss!"

Li Ya raised her hand to wipe the sweat from her forehead, still holding the wrench in her hand. Her smile was very sweet: "I am happy to do these things!"

After saying that, Li Ya asked Su Yi for the location of the scientific research room, went out and dived in.

The location of the research room is in the room of the original neighbor next door. Su Yi has never seen what the research room looks like, so he followed curiously.

From the outside, the research room is similar to a normal residential house, with ordinary wooden doors.

But after pushing open the door, there are all kinds of strange research props, high-power microscopes, chemical workbenches, high-precision cutting tools and machines... There are many instruments that Su Yi has never seen before, let alone how to use them.

But Li Ya is different. She is familiar with the place and fiddles with the research instruments in the room with light movements.

Looking at her expression, she seems to enjoy it very much.

After a simple observation for a moment, Su Yi did not disturb her and quietly left the room.

After returning to the main house, Su Yi found that he seemed to be the only idle person in the entire shelter.

Li Ya was busy with the renovation of the building and the development of the technology tree project.

Jiang Xiaoci was busy counting and sorting materials, and planning the future development of the shelter.

Even Lin Yue, who was sleeping normally, was a meritorious person with an injury, and it was natural for him to sleep.

"Well... How about I take a nap too?"

Su Yi scratched his head, and he found that he really had nothing to do.

Even if he wanted to further transform the shelter, there was no survival point, so he simply fell beside Lin Yue, closed his eyes and fell asleep.

When Su Yi opened his eyes again, he saw a red.

The sky outside the window was already bright, and the high temperature sun was still madly torturing every creature on this planet.

Perhaps because the hidden danger of the mob was solved, Su Yi slept particularly sweetly.

When he turned over and got out of bed, he found that Lin Yue had disappeared.

At this time, Jiang Xiaoci came from outside, holding two plates of hot and fragrant dishes in his hands.

"Sir, you're awake."

Jiang Xiaoci smiled and greeted Su Yi: "Lunch is just ready, come and eat."

"What time is it now?"

"Sir, it's already 12:10 p.m."

"I slept for so long? By the way... where did you cook?"

Su Yi sat at the dining table, a little surprised: "I remember, didn't the gas in our house stop?"

"The neighbor downstairs has a gas tank and a stove at home. I thought some of the food in the supplies was not very durable, so I decided to cook this meal."

Jiang Xiaoci explained gently: "You told me yesterday that I would decide all these matters, big or small, without discussing them with you."

"Yes, that's right, you did a good job."

Su Yi nodded, he looked around the house, and sighed.

Before going to bed, the whole house was very messy, and the air was still filled with lingering heat and stench.

In the past few days of the doomsday, Su Yi had no mood to clean the room at all, and Lin Yue and Li Ya, the two girls, were not good at doing housework.

But now, after waking up from a good sleep, the whole house was clean, tidy and bright. The foul smell in the air was gone, replaced by a faint sweet fragrance.

What surprised Su Yi the most was that he clearly found that the temperature in the room was a little cool, it seemed to be only around 30 degrees.

You know, the global high temperature is 70 degrees now, and the temperature of 30 degrees can almost be called winter in relative terms!

"Why... so cool?"

Su Yi murmured, and he looked around and found that the freezer had been adjusted by Jiang Xiaoci and placed at the door of the room.

And the counter was opened, and a simple device similar to an exhaust fan was placed outside, which was constantly drawing cold air from the freezer into the house.

"Air conditioning!"

Su Yi widened his eyes and felt incredible: "Xiaoci, did you do this?"

This is not a freezer, this is clearly an air conditioner!

Su Yi had thought about doing something similar before, but he never took care of it. Instead, he asked Jiang Xiaoci to do these little details now.

"It's not me, it's Miss Li."

Jiang Xiaoci shook his head and didn't take credit: "She made the device, which can make Mr. sleep better."

"If you don't tell her, Li Ya won't do these things on her own initiative."

Su Yi smiled. He knew Li Ya's personality. She was a relatively passive scientific research talent. Most of the time, she was used to following orders and rarely took the initiative to do anything.

But Jiang Xiaoci was different. She was very subjective and would think about what to do independently and try her best to do it well.

The brand new house in front of her was the best proof.

It was just one night. Su Yi sat at the dining table, looking at the bright and clean houses around him. He felt as if he had returned to the days before the end of the world.

But Su Yi's trance did not last too long, and he was soon interrupted by the new information prompt in front of him.

[Congratulations! Staying in the shelter for 24 hours triggers talent rewards! 】
