It's reasonable to have more than 100 million vests in the world of science, right?

Chapter 669 Feels a bit familiar

"Oh." Kawasei Machi responded subconsciously, then reacted and looked at Machiru with a puzzled look, "Huh?? What's wrong with your tone of coaxing a child??"

Shinryu uttered a "huh" and said, "You just behaved like a child who is afraid of injections."

Kawasho Machi: “…”

After drawing blood, Kawasho Shinryu took a medical cotton swab that was broken into pieces and medical tape and pressed it on the needle hole for him. He left a few words and turned away.

"You take a good rest, I'll go take care of some things."

Kawasho Machi: “???”

"Then we'll leave first, remember to eat something."

After Conan finished speaking, he walked out of the room with Professor Agasa, Okiya and others.

As soon as the door was closed, Kawasho Machika's confused expression instantly disappeared, and he began to drink the still hot porridge leisurely.

Well, after confirming the smell, it was made by Haibara Ai.

Conan and Professor Agasa followed Kawasaki Shinri to Agasa's house next door, but Okiya Aoi did not follow because he knew that Haibara Ai resisted him.

Kawasei Maru turned to look at Dr. Agasa and said, "I want to borrow the laboratory."

"can."

Before Dr. Agasa spoke, Haibara Ai, who was standing at the door leading to the underground laboratory, spoke first.

Kawasho Shinryu glanced at her, thanked her, and stepped in.

Conan and the others followed behind.

After Kawasaki Shinryu finished the blood test, Conan couldn't wait to ask, "What are the results?"

"As expected, he was injected with a recovery drug, but it was also a short-term drug in the experimental stage. He may not be able to maintain his current state for long."

Kawasei Shinryu looked at the results displayed on the computer with a calm look, "It's obvious that Death used Zhenzhi as a mobile experimental subject."

After bringing Kawasaki Masashi back yesterday, Conan called Kawasaki Masashi at Agasa's house and learned some things from him.

Kawasaki Machika was once injected with drugs by Death, and the effect of the drugs was the opposite of APTX-4869 that Conan and the others took.

The real effect of that drug is rejuvenation, not like APTX-4869 which has a high probability of killing people, or a small probability of making people smaller like Conan and the others.

But that kind of drug has a big flaw, for example, the true knowledge of a child state and the true knowledge memory of an adult state are not the same.

Death has developed another drug for this situation. Since Kawasho Machika was one of the first people to be injected with the 'rejuvenation' drug, they did not hesitate to come to them just to experiment with the effect of this drug.

But the results are obvious.

It was completely useless and instead allowed Kawasho Machi to return to his adult state.

It was precisely because their memories were not connected that Kawasho Shinryu hid these things from him.

Glancing at Conan who was lost in thought, Kawasho Shinryu interrupted his thoughts in a calm voice, "Don't think that the drug that Shinji was injected with last night will have the same effect on you."

Conan didn't feel guilty when his little thought was guessed, "I was just guessing."

On second thought, he suddenly remembered the medicine that Bechfinger had once given him!

"By the way, Bechfinger once gave me a drug that could help me recover. Could it be related to this?" His eyes lit up, and he suddenly became excited and expectant.

After hearing this, Kawasho Shinryu thought for a while in silence, "That should be the drug that was researched after Shinji was injected with drugs and became smaller, but it has no effect on Shinji."

As he said this, he lowered his eyes to look at Conan, "That guy Bechfinger doesn't understand this kind of thing, and you really dare to listen to and do what he said."

Conan was speechless for a moment and laughed twice, trying to fool the conversation. Although he now thinks that he was too reckless, at that time he really couldn't bear to see Xiaolan waiting for him in the snowy night, so he couldn't help but drink.

All I can say is, should we be thankful that he has a long life or is lucky... after all, he did manage to recover briefly at that time.

"What medicine?" Haibara Ai, who had been quiet on the side, suddenly spoke.

She glanced at Conan, and this incident probably happened before they met.

As expected, this guy was not afraid of death before and dared to try any medicine.

"You want to study it?" Kawasei Shinryu glanced at Huihara Ai, then took out his phone and edited a text message, "I'll have someone send it over."

Conan's eyes suddenly brightened again.

The experimental antidote that Huihara is currently developing is becoming less and less effective for him, but if he can get some inspiration from the medicine that Bechfinger once gave him, perhaps the results of the antidote development will improve.

Noticing Conan's excitement, Huihara Ai sneered and poured a basin of cold water with ice cubes on him. "Don't be too happy too soon. Even if the drug is effective, what if you become resistant to it?"

Sure enough, Conan not only calmed down, he even looked a little depressed.

"Then what about Zhenzhi?" Seeing that they all fell silent, Dr. Agasa spoke with a little concern.

Kawasho Shinryu deleted the information about the 'rejuvenation' drug on his computer and replied: "You don't need to worry about Machi in his adult state, but Death will definitely send someone to keep an eye on him, and there's no telling when Machi will turn into a child again."

"Does he know anything about Death?" Conan asked.

"Know a little, but not much."

After sorting out everything, Kawasei Mahiro returned to Kudo's house again to check on Kawasei Machi's condition.

As a person who was suddenly brought home by someone else, Kawasho Machika was currently wearing Okiya Aoi's clothes.

He combed his thigh-length pink hair, and when he saw Kawasei Maru, he happily floated over and hugged his shoulders, "Hey, Maru~ Don't always have a sullen face."

"Just stay here for now, and call me if you have anything."

Kawasho Shinryu glanced at him, without breaking free from his embrace, and just said something in a calm voice.

"Huh? Why?" Kawasho Masahiro looked surprised and walked out with his arm around his shoulder.

“Stop asking why.”

Zhenliu still spoke coldly.

"Okay." Kawasei Machi said indifferently, "Although I don't know what you are investigating, I will just listen to you."

Seeing Conan appear here, Zhenzhi raised his hand and waved at them, "Hi."

Then he brought Zhenliu in front of him and asked in a low voice: "I have a question, what kind of person is Mr. Okiya? I always feel that he is a little familiar."
