Yagihara is now 75 years old, and his experience is naturally above everyone else.

Everyone was very excited to hear it, and there were more cases to find more useful clues.

The little old man looked very careful, and did not explain on the spot, but led everyone to his car.

He is an expert in biology and genetics, has cooperated with many large companies, confidentiality is also the norm in his life, and his car is professionally protected from eavesdropping.

"This matter, I am also hearsay, I can't guarantee its authenticity, and it still involves some state secrets, please be considerate of the troubles.

At that time, I was still a graduate student, and I followed my supervisor to do some research on biological variation, including benign variants, and of course some lesions.

At that time, I was still a naïve silly boy, influenced by the superhero plot of Superman or something in Country M, and I always fantasized about being able to invent a drug, or substance, that could make people look like Superman and Hulk.

I've always been a happy and naïve guy, and my mentor knows this, so our relationship is more casual and friendly than other students, and sometimes, I will casually say my ridiculous thoughts, and my classmates will inevitably laugh at them when they hear them.

My teacher always smiled and shook his head, and then pretended to be serious, and said, "Yagi, you bastard, do you know what the consequences of that will be?"

Once, when we were busy late at an animal experiment center in the suburbs, I asked my teacher to drink at a food stall next to the river.

The teacher suddenly hit me on the head with chopsticks and said, Yagi, how can you have such crazy thoughts?

I'll tell you the truth, maybe it's influenced by those superhuman hulks and the like, I always think that human beings can continue to evolve, teacher, you see, whales are obviously mammals, but they can live in the sea, some animals that originally lived in the sea, can go to the land, even to the sky, the strength of the bear is very strong, the leopard is very fast, but what about humans? Physically, humans are almost the weakest animals.

The teacher laughed and scolded me while laughing, you idiot, the human brain is the smartest.

I retorted unreasonably, but in the harsh and complex natural environment, human beings even have a problem of survival, so what's the use of a smart brain?

Polar bears can live bare-chested in the ice and snow, but humans can freeze to death in a few hours, and some viruses can easily kill humans, but there is nothing they can do about some animals.

The teacher was silent for a while, then sighed and said, Yagi, I really hope you kid doesn't become a madman.

I said, "How so, teacher, do you see that I have a precursor to mental illness?"

Hahahaha, the teacher was amused to laugh again, and scolded, can't a mentally healthy person be a madman? Some guys, too sane, more crazy than crazy.

I heard the overtones in the teacher's words, and hurriedly asked him if he knew some sane madman.

The teacher pouted his mouth and gave a heavy sigh of gratitude, and said, "Oh, Yagi, if it weren't for you kid, I might have to take it into the coffin."

As soon as I saw that the teacher was lost in thought, I knew that he was going to open the conversation, so I quickly shut down and waited quietly.

My teacher told me a story about when he was a student.

Don't be funny, that happened more than 100 years ago.

At that time, he and his teacher were also my ancestors, I had never met him, and it was said that he was in his sixties at the time.

He and his teacher went to sort out a document left over from the time of Emperor Hirohito, you know what happened in that era, under the influence of ultra-right militarist sentiment, the whole of Japan went crazy, began to expand aggression abroad, and even created a Unit 731.

I suspect that the batch of documents they were dealing with at the time was similar to that of the unit. ”

Hearing this, whether it was Eko Yamamoto, even Suzu Kurokawa widened her eyes and looked at Yagihara in a daze.

"Even, I suspect that the agency to which the documents belong may be the predecessor of Unit 731, or the headquarters in Japan, because those documents predate the activities of Unit 731 in China.

At that time, the documents had been largely erased, and many of them were unreadable, but some of the words and photographs were still preserved.

The teacher was an extremely attentive and sensitive person, although he was a student, his knowledge and thinking ability at that time was already very good, and it didn't take him a few days to put together those snowflake-like graphic fragments into a set of self-justifying stories.

He speculated that there had been a major epidemic in Ezo, a small fishing village in Hokkaido, and that the specific cause and illness of the epidemic were no longer available.

However, the plague of the epidemic was mentioned several times in those sources, so the teacher deduced that someone was studying the epidemic and using the virus extracted from it for human experiments.

Some scattered photos also proved the teacher's inference that there were rats as big as dogs, rabbits as big as pigs, and some other animals with abnormal growth.

However, these are scattered fragments, and the whole experiment cannot be seen, and they are all on animals.

The teacher thought to himself that in that era of madness, there must have been human experiments.

In the teacher's eyes, the dirty, smelly and musty warehouse had become a gold mine.

Eventually, he found fragments of three photographs, photographs of human experiments, in a large iron bucket filled with ashes, which must have been used by predecessors to burn materials.

There are two photographs of the content, only below the knee remains, and one is supposed to be a close-up of the arm, leaving the image from the elbow to the hand.

The legs, feet, arms, and hands in the photograph are unusually thick and well-developed, and the muscle groups are almost sickly protruding, like exaggerated King Kong statues. ”

Yagihara said for a while, paused to drink slowly, and watched the reaction of the three women.

"Your teacher, did you do in-depth research?" Suzu Kurokawa asked eagerly.

"No," Yagihara shook his head regretfully and sighed, "When my teacher was on the rise, the news was known by the Americans, and MacArthur was like the Emperor Taishang in Japan, knowing that the Japanese government was dealing with a batch of wartime secret documents, so he sent someone to snatch the things. ”

"Oh, the muscles have become abnormally developed, which is very similar to the situation of Tayama Shimitsu." Suzu Kurokawa said.

"Not only that, although the data at that time did not show any side effects, it can be boldly inferred that on the battlefield at that time, there were no reports of any unusually muscular Japanese soldiers, which shows that their human experiments failed, and even until they were defeated and surrendered, they were unsuccessful." Thousand-Handed Butterfly reasoned.

"Well, there must be side effects, according to the teacher's inference, the owners of those hands and feet are at least about 1.9 meters tall, which is a mythical giant for the Japanese people who were only 1.5 meters tall at that time.

From a biological point of view, if a small person of 1.5 meters grows to 1.9 meters in a short period of time, his muscles, bones, and various important organs will suffer huge side effects. Yagiwara affirmed Senjutsu's inference.

"The name of that institution? What is it, it can't be 731, right? Eko Yamamoto asked cautiously.

"Haha, of course not, the names of the relevant agencies, addresses, personnel and the like in those documents have been erased, and some even the dates have been erased." Yagihara explained with a smile.

"However, it's not like there are no clues, at least, we know where those documents are."

Thousand-Handed Butterfly snapped her fingers and smiled charmingly and confidently.
