Although Eko Yamamoto has seen how old Tayama Shimitsu looks now, this kind of great change that happened in an instant still frightened her.

She screamed and grabbed Thousand-Hand Butterfly's arm hard.

Thousand-handed butterfly saw her face frightened, hugged her tightly, and continued to comfort her.

"This should be an obvious symptom of poisoning."

After a while, Eko Yamamoto straightened up from Senjutsu Butterfly's arms and said firmly.

This point, the Thousand Hands Butterfly has already explained just now, and the situation of Tayama Zhiguang has been planned to be poisoned. So she didn't repeat it, but asked Eiko Yamamoto directly.

"Do you have any ideas?"

"What about the blood test report? Didn't you notice anything suspicious in his blood? ”

"Of course there is, but nothing out of the ordinary has been found."

"Take blood, draw blood from the brain, and brain effusion, and test it again." Eko Yamamoto insisted eagerly.

"You-"

"I'll explain it to you later, let's do it first."

Yamamoto Eko was resolute, no matter how you say it, it was a clue, and Senjutsu Butterfly hurriedly found the attending physician and re-examined it according to Yamamoto Eko's opinion.

After 30 minutes, the attending physician gave a test sheet.

Compared with the blood test report just now, there is an additional substance called "temozolomide". This is a specific drug for the treatment of brain cancer.

"This-Tayama Zhiguang has brain cancer?" Thousand-Handed Butterfly looked at the attending physician and asked.

"No, I was also very surprised to find this, and besides, the amount of this drug is very small, far lower than the normal dose, and these drugs quickly gather in the brain after entering the human body, so I didn't find it until I took a blood test before."

Eko Yamamoto winked at Senju Butterfly and motioned for her to find another convenient place to speak.

"Is this what you want to check?" Thousand-handed butterfly asked rhetorically.

Eko Yamamoto nodded vigorously, bit her lip, stared into the eyes of the Thousand Hands Butterfly, and said word by word, "It's the same as my father's situation." ”

Yamamoto Eko's sentence startled the Thousand Hands Butterfly, lowered her voice and exclaimed in surprise: "What? His Excellency Faith Tiger he, he's-"

"No, that's not what it means," Eko Yamamoto quickly waved her hand and explained, "It was two years ago. ”

"That time? At that time, the news said that Mr. Yamamoto had a nervous breakdown due to long-term exertion, but it was rumored that it was a very strange headache, so what did it have to do with this? ”

"Yes, it is indeed a very strange headache, at that time, considering the complexity and strangeness of the condition, it was announced that it was a neurasthenia, and the doctor's final statement was also an induced neurasthenia, but the process was indeed a little weird.

My father was around for the first time, and the situation was very similar to Tayama Zhimitsu, with twitching features, sweating profusely, and becoming manic and active, but my father's condition was much lighter than Tayama's, and the whole person looked quite healthy, but there was some slight damage to the brain and nervous system. ”

"What about temozolomide?"

"My father has always been a serious and steady person, and the situation was too weird at that time, so we asked the doctor to do an examination, and found that kind of drug ingredient in the cerebral effusion, and the dosage was very small."

"That-Tian Shan's case can be regarded as the second case."

"Well, though, it's best to keep my father's affairs secret."

"I know, I heard about your encounter with an assassin yesterday."

"The trouble is, temozolomide, I've asked almost all the experts in pharmacology, and it's impossible for this drug to cause the kind of symptoms that my father and Tayama are experiencing."

"This point can be taken slowly, now that there is one more case, there is a little more certainty, maybe the two of Kurokawa Suzu and Yagihara can make any special discoveries."

The two of them waited until half past three in the afternoon before the news came from Suzu Kurokawa - of course, this was already very fast compared to the difficulty of their work.

The first to explain was Suzu Kurokawa.

"Tayama Zhimitsu's condition can be temporarily understood as a lesion, or poisoning, which has been inferred by Officer Senju, and this inference is also supported by the patient's onset characteristics, and we can call this poison that has not yet been discovered Substance X for the time being.

Through the observation of his body and various organs and tissues, this substance X mainly acts on his brain and the nervous system of the brain.

The effect of this substance is somewhat similar to cell division hormone, which makes Tayama Zhimitsu's brain and brain nerves complete the metabolism of a normal person for more than 30 years in three hours, making his brain rapidly aging into a state of suspended animation.

In the process, his brain affects hormone secretion, which leads to rapid growth and aging of muscles and bones.

The above is the medical explanation of the whole process of Tayama Zhimitsu.

Through the observation and inference of his metabolic process, the substance X in his body was completely dissolved about 7 hours ago, that is, at about 2 o'clock in the morning, so we could not find out what this substance was later.

However, this substance still caused him very serious sequelae, you don't see that he is very weak now, but the rate of cell metabolism and aging is much faster than ordinary people, as little as a year, at most three years, he will die of complete old age. ”

Suzu Kurokawa nodded, motioning for Yagihara to continue.

"The question on my side is relatively simple, Senjuhime and Ms. Kurokawa's inference is reasonable, this is a substance that can directly act on the human genome.

We know that common poisons usually have a dosage requirement before they cause a toxic reaction in the human body.

However, some substances can directly act on the human genome and cause genetic mutations, which can cause some kind of poisoning or disease reaction. For example, the aristolochia lactam in Houttuynia cordata, even if only one molecule invades the body's cells, can cause cancer in the kidneys.

The same is true for this substance X, their toxicity, which has no dosage requirements, is at the molecular level.

Even if only a few molecules enter the human body, they can cause different degrees of poisoning effects.

As for the temozolomide just discovered, this is a targeted drug for the treatment of brain cancer, which can act precisely on the human brain.

Its role is supposed to be to carry - responsible for transporting that extremely small amount of substance X to Tayama Zhimitsu's brain. This is a bit like the medicine introduction in traditional Chinese medicine, which is to guide the drug into a specific part or organ.

Of course, as Ms. Kurokawa said, this substance X works by causing genetic mutations that change the speed and cycle of brain growth and aging. ”

"In addition, I need to add one thing," Kurokawa Suzu saw Yagiwara finish speaking, and continued: "This substance is one of the biggest differences from the poisons seen before, the poisons seen before are all directly killing human cells, thus causing damage to human organs and life, this X substance, but it is an activator, a catalyst, which can make the cells of people and maybe plants grow wildly, and then age rapidly. ”

"You think it's a substance that hasn't been discovered yet?" Teko Yamamoto asked.

"Yes, in animal husbandry and agriculture, there are also some drugs that can promote the growth of plants and animals, but those drugs are still much less effective than the X substance we are currently experiencing, and those substances cannot directly act at the genetic level like X substance." Yagihara explained.

"Professor Yagi and I suggested that we first name this substance as substance X, and assume that Tayama Zhimitsu was poisoned, but unfortunately, in this case, substance X cannot be used as a criminal investigation clue." After all, Suzu Kurokawa is an advisor to the National Police Agency and knows the needs of Senju Butterfly.

"However, I have heard a rumor that describes a somewhat similar situation to Mr. Tayama Shimitsu."
