Jin Shu opened the first door in front of them. Just when the four thought that the base was inside the door, they were surprised to find that there was another door fifty meters away.

In the 50-meter passage between the two doors, four single beds have been set up, separated by a curtain. All the bedding is provided, and the male and female areas are clearly separated, as there is a separate toilet, washbasin, and wardrobe on one side of the curtain.

The other side was quite simple: a small urinal, two blue basins containing two towels and two sets of toiletries, and nothing else.

Jin Shu looked at the pale-faced girl and handed her a sanitary napkin and a painkiller.

"The water pipes here are connected to the water heater. Hot water is available for you to take. Go and take care of it first, then come back to the meeting point."

The girl glanced at her, took the things, and then, with the help of another girl, walked behind the curtain.

The remaining two boys curiously observed everything before them.

"Water heater, toilet... how did you do that?"

"You'll see later. Take a break, I'll be there in a bit."

In front of the two people, Jin Shu took out her key, opened the second door, went inside, and then closed it again in front of them.

Back in her living area, Liang Qingzhi, who was sitting on the sofa reading a book, stood up.

"You let them in."

"Um."

"This is not a wise approach. People's greed will swell, especially men. They will keep testing your limits and find it difficult to submit to a woman's control."

"Did you consider your own situation when you said these things?"

Liang Qingzhi said with a serious expression.

"The fact that I can recognize all of this means that I am different from ordinary men. I have never defined my own gender since I was a child. I don't want to be bound by gender to do what the public considers normal. So, you don't have to treat me as a man. I am just a person."

Jin Shu nodded, admiring this person from the bottom of her heart.

It's truly remarkable for a man to say something like that. Unbound by gender and passionate about what he wants to do, it's no wonder he can become a savior.

However, Jin Shu only listened casually to what he said, picking out the useful parts.

For example, his opinion that men are unreliable is absolutely correct.

Therefore, Jin Shu kept them outside the door, and until the research made progress, she would usually have Liang Qingzhi come out to discuss and exchange ideas with them.

With four more people at the base, the daily electricity consumption has increased significantly. Fortunately, the generator that Liang Qingzhi helped modify can now generate electricity not only from diesel fuel but also from solar power.

Most importantly, he not only knows how to modify, but also how to upgrade. The generator that could only provide power for a dozen hours before can now generate electricity for more than thirty hours after absorbing a whole day's worth of solar energy, thanks to Liang Qingzhi's tinkering.

Every morning, in addition to exercising, farming, and cooking for Liang Qingzhi, Jin Shu now has one more thing to do: prepare the ingredients for the four people outside for the day.

They did it themselves, after all, they were mental workers, so Jin Shu didn't treat them badly. She tried her best to make the food balanced every day, and the dishes were different every week.

Anyway, she has so many supplies that several people could eat them for a lifetime. Rather than wasting them after she dies, she might as well take them out and enjoy them now.

Before the four arrived, Liang Qingzhi spent her days drinking tea and reading books, eating directly at mealtimes, and occasionally helping to upgrade the base's ventilation, electricity, and indoor air circulation.

But ever since the four of them arrived and learned of Liang Qingzhi's identity, they have had countless questions to ask him every day.

Liang Qingzhi didn't want to pay attention to them, but Jin Shu insisted that he go outside every day to do research with the four of them.

Living under someone else's roof, and having to eat their food, Liang Qingzhi could only patiently leave her living area at the appointed time each day and then find another place to sit down and continue reading.

The four people outside saw him and felt as if they had seen a god descend to earth. They were so careful that they were afraid of doing something wrong and displeasing this great god.

Jin Shu didn't know much about their major, so she asked one of the girls.

"What does Liang Qingzhi mean to you?"

"He should be considered the Jerusalem of our environmental physics community. Without him, there would be no such major. All the content we learn in class now was compiled by Professor Liang and his students."

If we see Mr. Liang's students at school, we can't wait to run up and ask for his autograph.

So can you imagine how much Teacher Liang holds in our hearts?

Jin Shu nodded.

When Liang Qingzhi was mentioned, the little girl's eyes lit up, and the fervor in them was unmistakable.

"The apocalypse has actually allowed me to be so close to Teacher Liang. I really feel like this is the luckiest thing that has ever happened to me."

"Do you know that your teacher, Mr. Liang, can't even boil water?"

“Great people should do great things; they shouldn’t waste time on these trivial matters. From now on, I’ll be in charge of boiling water for Teacher Liang!”

"Very good, Teacher Liang needs a diligent and hardworking student like you."

If Jin Shu had known that these students admired Liang Qingzhi so much, she wouldn't have needed to go through so much trouble serving that "ancestor" every day. She could have just handed the work over to these college students.

They're actually enjoying it.

The girl's name was Zhou Zhizhi. She called Jin Shu "Sister Shu" when she saw her. She was very insightful and quick-witted, and had no arrogance whatsoever that of a high-achieving student.

Most importantly, this girl is also a great cook; Jin Shu tried it and found it to be very delicious.

So she handed over Liang Qingzhi's three meals a day to Zhou Zhizhi without hesitation.

That evening, Jin Shu stewed a single serving of pig's trotter soup, just the right amount for one bowl. Then, when she turned around, she saw Liang Qingzhi standing behind her with the bowl in her hand.

The other person silently looked at the empty casserole, then fixed their gaze on Jin Shu's bowl.

"What about mine?"

"Someone will prepare for you, so you can eat with them from now on, which will save you the trouble of going in and out."

"I've decided. We'll move this door further in to expand the passageway. We'll also set up a lounge for you outside. Oh, and by the way, don't you still need a research lab? I'll go out tonight to get the equipment you need. Give me a list, and I'll go find it."

"Why?"

"Huh? What do you mean why? You said yourself that you need a separate research lab."

"Why am I made to live outside?"

Liang Qingzhi seemed not to have heard a single word that followed.

His silent gaze dimmed considerably, and he seemed to have lost all his energy. His eyes fell on Jin Shu with a strange expression.
