But little Sun was persistent and said good morning, good afternoon and good night to him every day. Occasionally, when he was sad, he would stretch out his thin little hand and poke him through the cage as a comfort.

Later, as they became more familiar with each other, they would occasionally chat quietly.

Little Sun told Kudo that he chose his name himself and he hoped to see the sun.

"Have you never seen the sun?" Kudo looked at him with a crooked face.

"No, I grew up here since I was three years old." Yang shook his head, "I don't remember anything before the age of three."

"I wish I could grow up quickly," Yang smiled, and two cute little pears appeared, "so I can leave this room."

"Yeah!" Kudo nodded.

Indeed, if you can survive the three-year experiment, you can leave this white hell and go outside.

"When I go out, you go out too, and we'll go see the sun together." Kudo held the railing of the cage, staring at the sun with his clear blue eyes, "But the sun is very bright, so remember to buy a pair of sunglasses."

"Yeah! I'll remember it." Yang nodded vigorously, his light brown eyes, almost orange, flashing with a strange light.

They would often chat with their backs against each other, imagining the future a few years from now - like two small grasses hugging each other for warmth in the dark, with a faint fluorescent light flickering between them.

That was Kudo's only spiritual support during that time.

——

The mortality rate in the experimental area for brain development is very high, but Kudo seems to be one of the few lucky ones.

He heard from the person in charge that he had a good compatibility with an experiment, so he would be the main experimental subject of that experimental project in the future.

Kudo didn't have any special feelings. Whether it was good or bad, it seemed to have nothing to do with him.

His only wish is to live for three years and go to see the sun with Yang.

Maybe, find mom and dad too.

But this wish is too slim, so Kudo usually pretends it doesn't exist.

On the first day of the new project, Kudo finished the experiment and lay on the operating table for five months.

The person in charge of the project performed a craniotomy on him that day, but an accident occurred unexpectedly, causing him to hover on the verge of death several times. In the end, he survived with the doctor's full efforts to save him.

Kudo heard that the person in charge that day was captured by the higher-ups and thrown into the sea because he was very important.

But this had nothing to do with him. Kudo only knew that he was alive and that he hadn't seen the sun for five months.

This also meant that he missed Yang's birthday.

Only then did Kudo begin to feel some resentment towards the person in charge.

He eagerly threw off the quilt and ran to the residential area, but he did not see Yang next to his cage.

Kudo quickly realized that Yang was already eight years old, and he had reached the standard age and could become a test subject.

Then we can only wait until night.

Kudo thought.

But he waited for a week.

During this period, Yang never came back.

Kudo had a bad feeling.

He picked a new female experimenter in the laboratory, raised her delicate face and smiled like Yang, and asked, "Sister, do you know where the experimental subject 116-b went?"

The new experimenters were not used to the mortality rate in human experiments, especially since most of the dead were **-year-old children.

But she can't change the status quo - she can't even choose her own life.

This kind-hearted experimenter who has not yet lost his conscience is the best to talk to. The young lady who was asked thought for a moment and said, "Group B, No. 116? It seems that he is dead."

"Oh, that's right. His body is so fragile that he couldn't even survive the first experiment..." The young lady said this with a bit of sadness.
