The houses for non-evolved individuals are very small, consisting of only one room. Families with more members can be allocated a larger single room.

Since non-evolved beings do not need to cook, and the nutritional supplements produce very little food waste, public restrooms are sufficient.

...

There are three main time periods in the underground base: the lighting time, the lighting time, and the lighting-out time.

The lights are on for twelve hours, corresponding to the daytime when people need to study and work; the lights are off for four hours, corresponding to the time after get off work; and the lights are off for eight hours at night.

It was dark at the base. Workers were in a hurry to leave work, children were in a hurry to get out of school, and crowds of people were rushing around.

Xia Chuhe's leisurely pace seemed out of place. She blended into the crowd and couldn't help but quicken her pace slightly.

Xia Chuhe stopped in front of Wang Yan's house.

The private room had a huge window, and Xia Chuhe saw that there were only four children in the room, fighting over food, which seemed to be the teething stones that Wang Yan had given Xia Chuhe to taste before.

There was only one teething stone left in the box, and the four children started fighting.

"This is mine, you just ate it!"

"I didn't, the seventh child eats a lot!"

...

Xia Chuhe hesitated whether to go in; she had just bought food in her space. Perhaps if she shared the food with the children, they wouldn't fight.

Just as Xia Chuhe was about to knock on the door, he suddenly heard a child say, "It's all Yan-ge's fault. Why did he only buy this little bit? If only he could earn more money and buy more food."

Xia Chuhe: "..."

After standing in front of Wang Yan's house for two minutes, people started to notice her.

Xia Chuhe went around to another direction and climbed onto the roof.

As if by some strange twist of fate, she activated the built-in audio and video recording function of her watch and even released the hummingbird, which had just finished eating and drinking.
