The little sister looked at the tears in the child's eyes, sighed, and said with gritted teeth, "But everyone will die one day, so don't be too sad..."

Kudo's eyes were already filled with tears, and his hands were clenched tightly.

Of course he knew that everyone was destined to die, and he had seen many corpses before, but those things had nothing to do with him.

The pain that does not happen to yourself will never be engraved in your heart.

He may feel regret, pain, and sadness at that time, but that is all because of empathy.

It is completely different from my own experience.

"Push? What are you doing here?" A woman came over and pulled the young lady away. She casually glanced at Kudo who lowered his head, then turned to the young lady and said, "Didn't I tell you not to communicate with the experimental subjects?"

"This won't do you any good." The woman pulled the young lady away.

Kudo stood there, with only one thought in his mind: "He didn't even make it through the first experiment."

How come?

Yang is mentally very strong, otherwise he wouldn't be able to smile so happily in a place like this.

Although mental strength seems to have nothing to do with physical strength, the desire to survive is very useful for rescue. He doesn't believe that Yang has no desire to survive.

The heart that seeks the truth began to beat violently again after a long absence.

He wanted to know the truth about Yang's death.

But the reality is completely different from his ideal. He is imprisoned in a brain development laboratory. No one will communicate with him, and he has no way to get the truth.

The subjects in the same room with him licked their wounds in silence, immersed in their own misery, and did not communicate with each other at all.

There was nothing he could do.

——

Subaru Okiya came back from outside and saw Kudo woke up, and asked, "Do you feel better?"

The boy was interrupted from his thoughts and slowly raised his eyes to look at him, "No."

Does this person think that the drip is a panacea? Will it get better right away?

“……”Okiya Subaru fell silent.

The room fell silent. Kudo withdrew his gaze and began to recall the past.

Yang's death was ultimately left unsolved because he had no way of getting the truth.

By the time he knew the truth, he was already twelve years old, which was two years later.

——

Kudo's twelve years old.

"The mission is accomplished. Please return to your room as soon as possible." The monitor smiled politely at him.

In front of him was the organization's first successful brain developer in decades.

Just now, they finished their brainwashing mission on him.

The twelve-year-old boy nodded slightly towards him, his still somewhat childish face showing an inhuman indifference.

Kudo stood at the door of the house prepared for him. His eyes passed over the "One House" at the door and stopped at the fingerprint lock on the big iron gate.

"Please use your fingerprint to unlock the door."

Kudo did as he was told, his sea-blue eyes filled with the incoherence of a puppet.

His eyes were like two beautiful glass beads, nothing but beauty.

"Please enter the room." The monitor led the way in front of him, while secretly observing him.

No curiosity about the things around you.

Not distracted.

No independent thinking.

No questions asked.

The monitor mentally marks the things that should be observed one by one with a ? symbol.

Finally, they stopped in front of a dark wooden door.
