Lin Xiao walked around the laboratory, quite interested in some of the research equipment inside.

After all, although he had been to many places before, he had really never been to this kind of laboratory for studying toxins, and everything felt a little new.

A researcher from the lab came over and explained to them what was going on.

"Nerve agents, also known as phosphate-containing agents, are poisons used to disrupt the normal conduction function of the nervous system." "The four most representative of the four neurotoxic agents are tabun, sarin, soman and viex. ”

"Oh, it turns out that sarin gas is also a nerve agent." Lin Xiao listened and nodded.

Sarin poison gas can be said to be famous, and Lin Xiao knows it.

Twenty years ago, sarin was the culprit in the poison gas incident that occurred in the Tokyo subway.

In the morning, during rush hour, the Tokyo subway was crowded as usual.

As soon as a subway train entered Tsukiji Station, passengers swarmed out, and suddenly some people collapsed to the ground, others staggered, many subway workers and passengers sat on the ground and coughed loudly, feeling dizzy, nauseous and difficult to breathe, many covered their eyes, saying that they could not see anything, and the scene was chaotic.

When the police received the news, they reacted quickly: the fire brigade and the medical rescue team quickly arrived at the scene, and rescuers in protective suits immediately took the poisoned person to the hospital.

In less than 30 minutes, anti-chemical warfare experts had arrived at the scene by helicopter to take samples.

More than 10,000 military and police cordoned off the scene and evacuated people.

The police immediately closed two subway lines, twenty-six stations.

After two and a half hours of detection and analysis, it was confirmed that sarin poisoning.

Three hours after the incident, the government published propaganda to calm people's mood and formed a 140-strong anti-chemical warfare unit to remove toxic substances from trains and stations, which was a great success in the overall rescue operation.

It was later confirmed that 16 stations, including Kasumigaseki and Tsukiji, were attacked by poison gas during that time.

The Tokyo subway sarin incident killed 12 people, poisoned about 5,500 people, and hospitalized more than 1,000 people.

On the day of the incident, several main subway lines around the seat of the Japanese government and the Diet were forced to close, affecting 26 subway stations and plunging traffic in Tokyo.

"What are nerve agents?" Han Ya asked with some curiosity.

"Nerve agents are a class of highly toxic, highly effective, and lethal agents that are non-irritating and only have a faint odor." The researcher explained, "Nerve agents, which can be used in a variety of munitions and missile warheads, can poison people through the respiratory tract, skin and other ways, inhibit the bioactive substance cholinesterase in the body, and destroy B." Acylcholine's conduction of nerve impulses kills people. ”

He explained that neurotoxic agents are organophosphates or organophosphates, which are particularly harmful to the brain, diaphragm and blood B. Acylcholinesterase activity has a strong inhibitory effect, resulting in B. Excessive accumulation of acylcholine in the body causes severe disturbances in the central and peripheral cholinergic nervous system.

Because of its strong toxicity and fast action, it can be absorbed through the skin, mucous membranes, gastrointestinal tract and lungs and other ways to cause systemic poisoning, and in addition, it is stable in nature, easy to produce, and has good use performance, so it has become the main chemical warfare agent in foreign military equipment.

"The main symptoms of poisoning after exposure to neurotoxic agents are miosis, salivation, nausea, vomiting, muscle tremors, spasms and nerve palsies, incontinence and death." The researchers explained, "It can be effectively protected by gas masks and skin protective equipment, and it is usually used. Tropine and pyridine. Aldehyde oxime drugs are used as antidotes, and phosphorus-solubilizing injections are injected intramuscularly when urgent. ”

Fang Shuyan also said that at present, a domestic academy of sciences has developed an organophosphorus degradation enzyme, which can efficiently degrade organophosphorus into non-toxic components by cutting the phospholipid bonds of organophosphorus.

"At present, this kind of decontamination preparation has been added to the anti-terrorism special service equipment in some large cities in China, and organophosphorus neurotoxic agents and organophosphorus pesticides belong to the same nature, so this enzyme can also be used to wash away residual pesticides in vegetables, which can be used at home, and all families with children can use this enzyme to clean vegetables and fruits." Fang Shuyan said.

"In this way, the market application prospect is still very broad, I don't know if it has been put into the market?" Lin Xiao was quite interested in this issue.

After all, food safety is a big problem now, and the phosphorus content of vegetables and fruits is the top priority.

If this digestion preparation can really be promoted in large quantities, as long as its advantages are obvious and the detoxification is effective, then there will be a lot of people who are willing to buy it.

"Lin Dashao is also interested in this?" Fang Shuyan asked with some curiosity.

"I still have a little spare money under my hands, and investing in some industries that are beneficial to the people can be regarded as a good deed." Lin Xiao snorted.

"Lin Dashao is really a rich man." Fang Shuyan nodded and said, "But this project has already been done, and it is the background of the military, so it is estimated that it will be difficult to get involved now." ”

"That's a bit of a pity." Lin Xiao replied regretfully.

In fact, this result is also to be expected, after all, the military's research institutes also have a lot of investment, and ordinary research units are simply not comparable to them.

And now the military is not short of money, so it is natural for a few companies with military backgrounds to transform some patented technologies that can be used for civilian use.

This kind of good thing is generally enjoyed by military companies, and it has little to do with outsiders.

Unless the input and output are disproportionate, the bureau will consider transferring some patented technology, for example, the investment in basic equipment is too large, and there is a large scale of the same type of company on the market, they naturally do not need to start a new business, and then build a company, just find a suitable company, cooperation.

"Actually, if it weren't for this reason, Lin Dashao would want to cooperate, which should be a good thing." Fang Shuyan said.

Lin Xiao nodded, in fact, he found that he had neglected this aspect of the matter a little.

After all, the military's research capability in some aspects is indeed much higher than that of the localities, and it occupies a great advantage, and if these patented technologies can be obtained and quickly transformed into productive forces, the business opportunities contained in them are absolutely very large.

Ordinary people naturally don't have this ability to cooperate with the military, but Lin Xiao does have this strength and this fund, and his father-in-law Han Shengxian himself presides over the work of the Military Commission, and Han Ya is the director of the special service, no matter who comes forward, he can help him facilitate this matter.

"I really didn't pay attention to this before, and it looks like I'm still a bit of a frog at the bottom of the well." Lin Xiao said.

"The military is always a bit troublesome, if it's not so special technology, you can think about it." Han Ya said on the side.

As the director of the Secret Service, Han Ya has more insider contact, so she has a deeper understanding of this aspect.

"By the way, how is the investigation going?" Lin Xiao asked Fang Shuyan.

Several of them have been in this underground research institute for more than an hour, and it stands to reason that their matter about the leakage of poison samples should be about the same.

"I'll take a look at the situation." Fang Shuyan nodded and replied, and then went to communicate with the person in charge of the security system next to him.

Lin Xiao said to Han Ya, "What do you think, how likely is it that there is an internal leak?" ”

"One hundred percent." Han Ya replied without hesitation, "This thing is only available here, and the production in the laboratory is also very small, if there is a little more, it will really kill people yesterday." ”

"Then, a master's student, there must be no way to take out the poison from here, so there must be a deeper hidden figure behind this, who is leading all this." Lin Xiao analyzed to Han Ya, "If you don't find out this person, the matter won't be over." ”

"It's hard to say now, after all, even the person directly responsible has not been identified." Han Ya was more pessimistic about this.

In such a laboratory, if there is no relevant record in the safety log, trying to find out the person responsible is almost equivalent to a fool's dream, and it is impossible at all.

"Found it!" At this time, Fang Shuyan over there suddenly shouted with some excitement.

"Oh?"

Lin Xiao and Han Ya glanced at each other, and they both felt a little surprised, it was indeed unbelievable that they had found the record so easily.

Could it be that the person who presided over the poisoning did not even think about hiding his identity, which is a bit strange and completely incomprehensible.

After the two of them walked over, the person in charge of the security system pointed to a record on the computer and said, "It was this number that took the poison sample, we only need to follow this number to call up the video at the time, and we will know who planned this." ”

"Then check it out, it's been more than an hour." Lin Xiao said, "If the time is delayed a little, it is very likely that the other party will slip away." ”

The laboratory also has a shift system, and some people are not present, so Lin Xiao is very worried about this matter.

In case the other party has already fled, then it is completely unnecessary for them to check the clues here.

"Okay, actually, it's going to be pretty quick now......" The head of the security system started typing that number into the computer, and then started calling up the recent surveillance video of that number, "Well, it's almost there, huh, who is this person?" Could it be, Director Liang?! How is this possible?! ”
