As Yi Bai opened the technology tree list, a dense array of technology projects was presented before him.
At the very top of the list was written [Laboratory Sequence], and below were various technology projects, such as: [Basic Power System], [Autonomous Water Resource System],
[Enhancement of Basic Defense Measures], [Prerequisite Project for Improving Living Facilities], [Enhancement of Scientific Research and Exploration Capabilities], [Agricultural Automation System], [Medical Aid Station], [Air Purification System], [Intelligent Monitoring Network], [Garbage Disposal Center], [Central Air-Conditioning Module].....
The numerous technology projects almost dazzled Yi Bai.
Even without looking at the detailed effects of these technology modules, just by looking at the names, one could imagine that if all these technology projects were activated, the shelter would undergo earth-shattering changes!
"Let me check the prices..."
Yi Bai examined carefully and muttered: "The power system costs 1,000 survival points, the autonomous water resource system is 1,000 points, the garbage disposal center is 300 points... and the central air-conditioning module is 800 points?"
"Damn, they're all so expensive!"
Yi Bai gasped in astonishment. Looking at the only 800 survival points he had left, he couldn't help but smile wryly.
"It seems that building the shelter is truly a long and arduous task. This is just a level 1 laboratory. There will probably be even more expensive technology projects later."
Yi Bai calculated how to maximize the benefits with these 800 points.
"The central air-conditioning is important, but for now, I can still endure the heat with ice water. The medical aid station? It's also good, but not the most essential."
"... Well, let's activate the [Enhancement of Scientific Research and Exploration Capabilities] module first! It costs 500 points, but it's the technology project that can bring the most immediate benefits at present!"
Yi Bai selected this project to view in detail.
[Enhancement of Scientific Research and Exploration Capabilities]: Consume 500 points, dispatch scientific research talents such as engineers and scientists to conduct research, which takes 10 hours. After successful research, it can increase the exploration benefits of the shelter by 10% and the research speed of technology tree projects by 10%.
These two 10 percents, although seemingly not much, but if accumulated, the additional benefits would be quite significant.
"I'll choose this one!"
"There are still 300 points left. Should I keep them or take a look again?"
Yi Bai pondered, and his eyes involuntarily fell on the [Garbage Disposal Center] technology project.
[Garbage Disposal Center]: Consume 300 points, dispatch scientific research talents such as engineers and scientists to conduct research, which takes 12 hours. Build fully automatic domestic waste disposal equipment in the shelter, which can harmlessly treat various types of waste.
"Exactly 300 points!"
Yi Bai hesitated only slightly and finally chose to purchase this project.
He had no choice. He really couldn't bear the stinking smell at home.
After losing the city's water supply, even flushing the toilet was impossible. Every day, a large amount of excrement had to be accumulated and then treated with nearly spoiled stinking water.
Even doing this, Yi Bai still felt a great pain about the waste of water resources.
Modern humans have a civilization, and naturally it is hard to endure living in an unsanitary environment.
Excrement breeds bacteria and is also a major threat to human survival.
[Selected technology projects. Please dispatch suitable talents to the research room for research.]
"Li Ya! Li Ya!"
Yi Bai quickly called Li Ya, who was downstairs. Li Ya poked her head upstairs and asked in confusion: "Boss, you called me?"
"How is the construction of the defense measures downstairs?"
"It's almost done. In another half an hour, the traps and the reinforcement of the entrance gate will be completed."
Li Ya said with a smile: "Although this building is a bit old, the materials are very solid. The original gate is an iron gate, which saves me from large-scale renovations."
"Well, take a good rest after you finish today. There will be a major project tomorrow."
Yi Bai nodded and informed Li Ya of the research projects of the two technology projects.
Upon hearing this, Li Ya's eyes lit up: "Boss, there's no need to wait until tomorrow. I can start right away!"
"Now?"
Yi Bai glanced out of the window. It was already pitch black outside: "It's already past 11 p.m. now. It's too late. You'd better take a good rest."
Yi Bai didn't want to overly exploit his subordinates, but Li Ya was very determined: "No! Boss, I can stay up all night to research!"
"I promise to complete the task before tomorrow night! I can give a military order!"
Li Ya was eager, and her beautiful eyes sparkled with enthusiasm for scientific research.
Yi Bai was helpless. He didn't expect that Li Ya, who looked delicate, was essentially a scientific research maniac.
"Sir, I also support Miss Li to conduct research now."
Jiang Xiaoci, who was standing by, suddenly spoke and softly gave her opinion: "This is an extraordinary time. Our lives depend on this. The earlier Miss Li can play her role, the more we can ensure everyone's safety."
"So, most of the time, we can't pay too much attention to the normal work and rest schedule but should adjust according to the actual situation."
Jiang Xiaoci spoke very tactfully. Yi Bai nodded and agreed: "Okay, let's do it this way. It's just that Li Ya will have to work hard."
"It's okay, boss!"
Li Ya raised her hand to wipe the sweat on her forehead. She was still holding a wrench in her hand, and her smile was very sweet: "I love doing these things!"
After saying that, Li Ya asked Yi Bai about the location of the research room and then rushed in.
The research room was located in the room of the former neighbor. Yi Bai had never seen what the research room looked like and curiously followed.
From the outside, the research room was similar to a normal residential room, with an ordinary wooden door.
But after opening the door, there were all kinds of strange research tools, high-power microscopes, chemical workbenches, high-precision cutting machine tools... There were many instruments that Yi Bai had never seen before, let alone knew how to use.
But Li Ya was different. She was very familiar with this place and skillfully manipulated the research instruments in the room.
Looking at her expression, she seemed to be enjoying it and having a great time.
After observing briefly, Yi Bai didn't disturb her and quietly left the room.
After returning to the main room, Yi Bai found that it seemed that he was the only idle person in the entire shelter.
Li Ya was busy renovating the building and researching technology tree projects.
Jiang Xiaoci was busy counting and classifying supplies and planning the future development of the shelter.
Even Lin Yue, who was sleeping and resting normally, was a meritorious person with injuries and had a legitimate reason to sleep.
"Well... maybe I should also go to sleep and rest?"
Yi Bai scratched his head. He found that he really had nothing to do.
Even if he wanted to further renovate the shelter, he didn't have any survival points. So he simply lay down beside Lin Yue and closed his eyes and fell asleep.
When Yi Bai opened his eyes again, everything was red.
The sky outside had brightened, and the high-temperature sun was still brutally tormenting every creature on this planet.
Perhaps because the threat of the thugs had been resolved, Yi Bai had a particularly sweet sleep.
When he got out of bed, he found that Lin Yue was nowhere to be seen.
At this time, Jiang Xiaoci came in from outside, carrying two plates of steaming and fragrant dishes.
"Sir, you're awake."
Jiang Xiaoci greeted Yi Bai with a smile: "Lunch is just ready. Come and eat."
"What time is it?"
"To answer your question, sir, it's already 12:10 p.m."
"I slept for so long? By the way... where did you cook?"
Yi Bai sat at the table, a bit surprised: "I remember that our gas supply was cut off, right?"
"The neighbor downstairs has a gas tank and a stove. I thought some of the food in the supplies were not very durable, so I decided to cook this meal."
Jiang Xiaoci explained gently: "You told me yesterday that I could make decisions about these trifles by myself without consulting you."
"Yes, that's right. You did a very good job."
Yi Bai nodded. He looked around the house and sighed.
Before going to sleep, the whole room was very messy, and the air was filled with lingering stuffiness and a stinking smell.
Since the doomsday began a few days ago, Yi Bai had no mood to clean the room. Lin Yue and Li Ya were not the kind of people who were good at doing housework.
But now, after waking up from a sleep, the whole house was clean, tidy and bright. The stinking smell in the air was gone, replaced by a faint sweet and fresh fragrance.
What surprised Yi Bai the most was that he clearly noticed that the temperature in the room was a bit cool, seemingly only around 30 degrees Celsius.
You know, the current global high temperature is 70 degrees Celsius. A temperature of 30 degrees Celsius is relatively speaking almost like winter!
"Why... is it so cool?"
Yi Bai murmured. He scanned around and found that Jiang Xiaoci had adjusted the position of the freezer and placed it at the door of the room.
And the freezer was opened, and a simple device similar to an exhaust fan was installed outside, continuously drawing the cold air from the freezer into the room.
"An air conditioner!"
Yi Bai widened his eyes in disbelief: "Xiaoci, did you do this?"
This was no longer a freezer. It was clearly an air conditioner!
Previously, Yi Bai had also thought about doing something similar, but he had never got around to it. Instead, Jiang Xiaoci had taken care of these small details now.
"It wasn't me. It was Miss Li."
Jiang Xiaoci shook her head and didn't take credit: "It was the device she made so that you could have a better sleep quality, sir."
"If you hadn't given the order, Miss Li wouldn't have taken the initiative to do these things."
Yi Bai smiled. He knew Li Ya's character. She was a rather passive scientific research talent. Most of the time, she was used to following orders and seldom took the initiative to do things.
But Jiang Xiaoci was different. She had a strong sense of initiative, would think independently about what to do, and try her best to do it well.
The completely new look of the house was the best proof.
Just in one night, Yi Bai sat at the table, looking at the bright and clean house around him. For a moment, he felt as if he had returned to the days before the doomsday.
But Yi Bai's trance didn't last long. Soon, his thoughts were interrupted by a new information prompt.
[Congratulations! The time you have stayed in the shelter has reached 24 hours, triggering a talent reward!]
