"Gray, do you have any impression?"

We can only try to pin our hopes on the scientific researcher Huihara Ai.

"No... I have no impression of it at all." Huiyuan Ai lowered her eyes and thought for a while, "But I did hear about human experiments."

She raised her head and looked towards the playground again, her tone inexplicable, "But, the only requirement for organizing human experiments is seven to nine years old, and the best experimental subject is seven years old."

"That is to say, if he was an experimental subject of the organization, he has at least spent five years in the laboratory so far."

Five years.

If we count from the time he was nine, he should have been five years old.

"Do you know what life in a laboratory is like?" Huiyuan stared at the playground with a vague tone, "Every day, all you see is white, and you have to deal with all kinds of chemical reagents."

"But I am the one who prepares the test reagents, and the test subjects are just the ones being injected. The fear of having a test reagent of unknown effect injected into the body will be remembered for the rest of your life."

She suddenly let out a breath, as if she had put down a heavy burden. "I'll go there with you after school today."

"Huh? But..." Conan was stunned for a moment, "You also know that he is a member of the organization, right?"

"If he is from the organization, wouldn't your situation be dangerous?"

Having said that, Conan wanted to reject her request.

Ai Haibara looked at Conan's sapphire blue pupils. She saw her own reflection in them. The colors and facial features were not clear, like a monster without a self.

"I have seen the subject before."

She suddenly said, "I was still a child at that time, and the subject was a little boy. He cried and ran towards me, hoping that I would save him."

"But I escaped, and the experimenters caught him by the wrist."

Huihara Ai's voice was calm. "I saw that his skin was pale, and there were large patches of pinholes and bruises on the exposed skin."

"All the experimental subjects live this kind of life." Huiyuan Ai said, "You can understand me."

"Besides, you will protect me too." The brown-haired girl smiled slightly.

"Of course." Hearing this, Conan was stunned for a moment, but soon he also laughed. :,,.
