During the demonstration, Lin Feng found that the dead corpse had actually undergone a cell reduction reaction, and radioactive substances and toxic chemicals were also detected in the blood, as for what caused the cultivator to die or these were the secrets of the cultivator's death?

Regarding radioactive substances, Lin Feng didn't believe that this kind of thing could kill cultivators, if it was radioactive substances that caused the sudden death of cultivators, then all cultivators here would have this kind of situation, especially ordinary people who didn't have any ability would die on the spot, from this point of view, radioactive substances should not be the cause of death.

There are some possibilities for toxic chemicals in the blood, but how do these chemicals get into the cultivator's body?

The cultivators had been resisting the enemy's attack at the city gate, and they didn't even have a chance to eat and drink, so how could they find these things in their bodies.

At present, the biggest possibility is the cause of the cell, cell necrosis, cell reduction, these symptoms are fatal.

Thinking of cell reduction, Lin Feng remembered one thing, cell reduction produces single cells, and single cells will cause the human body to produce biotoxins, which are more serious and highly toxic than chemicals.

Biotoxins are toxic substances produced by various organisms, which are natural toxins, and there are many types of biotoxins, including almost all types of compounds, and their biological activities are also very complex, which can have an impact on human physiological functions, and the scope and degree of influence depend on which kind of organism the biotoxin comes from, and the toxicity is very difficult to judge.

The chemical toxic substance detector has detected a toxic substance in the blood, tetraethyl pyrophosphate, which was used as an insecticide in Lin Feng's original world, but there is no such substance in this last world, but now this kind of substance has appeared in the body of the dead cultivator, could it be that there are still people who have crossed over here from the original world?

Tetraethyl pyrophosphate reacts particularly violently to humans, and under normal circumstances, one gram of tetraethyl pyrophosphate can kill humans, but its own characteristics make tetraethyl pyrophosphate kill humans in the case of 0.3 grams, and the toxicity will increase rapidly with body temperature, and the higher the body temperature, the more violent the toxicity.

Lin Feng didn't understand now, why this substance appeared here, even if someone from the original world had crossed here, there was no reason to kill the cultivator, and he still used this forbidden chemical substance.

Considering the characteristics of the corpse and the composition of the chemicals in the body, Lin Feng made a conjecture.

"Tetraethyl pyrophosphate begins to produce toxic side effects in the bodies of cultivators, but the body of cultivators is not afraid of severe toxicity, so tetraethyl pyrophosphate temporarily accumulates in the body, due to external stimulation, it may be the fluctuation caused by the attack or the long-term retention of toxic substances that reduce immunity, no matter what the possibility is, it is to make the tetraethyl pyrophosphate mutate, which can destroy and reduce the cells of the organism, so this result will appear on the corpse."

Although this is just Lin Feng's conjecture, but it is already very theoretical, in order to prove his idea, Lin Feng entered the supermarket again and came to the library area to look for relevant information, but unfortunately, the books in the supermarket are not related to chemistry.

Lin Feng, who was a little disappointed, came out of the supermarket, he saw the expectant eyes of the brothers around him who were still waiting for the results, Lin Feng suddenly thought, is everyone infected with this toxic substance.

So Lin Feng called Mr. Qian and asked him to organize everyone to line up to draw blood to check whether there were toxic substances in the body, if the test result was the same as Lin Feng thought, then Lin Feng would have a way to treat everyone.

The cultivators saw that Lin Feng already had some clues, and heard that Manager Qian said that everyone needed to line up to test their blood to prove Lin Feng's conjecture, everyone thought that Lin Feng should know something, since there was hope to be saved, of course everyone supported Lin Feng.

The test results came out quickly, among all the cultivators, only the original team of the original Beishan base had tetraethyl pyrophosphate in their blood, while the cultivators that Lin Feng later brought to the Beishan base did not have this kind of thing in their blood, it seemed that this required careful questioning of those cultivators in the original Beishan base.

At Lin Feng's suggestion, Chief Manager Qian and Elder Sima respectively brought the two cultivators from the Beishan Base to the edge of the woods, Lin Feng was responsible for questioning, while Chief Manager Qian and Elder Sima were responsible for patrolling around to prevent others from eavesdropping or enemies attacking.

"You haven't been with me for long, but I shouldn't have anything wrong with you, right? I wonder if you can be honest with me? ”

Although Lin Feng's tone was very good when he questioned these two subordinates, Lin Feng still released all the energy fluctuations on his body, and under this powerful fluctuation, the two subordinates sweated profusely on their heads, and they were even more afraid of Lin Feng.

"Back to the leader, we follow you wholeheartedly, we didn't leave even when the war broke out, we really regard you as our own leader, we will answer you whatever you want."

One of his subordinates did not have a high cultivation level, and under this powerful energy fluctuation, his brain had already begun to lose control, and his mind had already been controlled by Lin Feng.

Thoughts can be controlled, but the truth of what is said is still to be decided by one's heart, even if Lin Feng controls the brains of his subordinates, but the memory in the brain Lin Feng cannot know, he can only let his subordinates personally say the most truthful answers.

"You answer me, before I came to the Beishan base, whether the cultivators in your base had eaten anything or injected any medicine, you must think carefully, you can't deceive, this is related to your life."

When the two men heard that their lives had something to do with something from the past, they began to try to remember what had happened.

The other subordinate seemed to have thought of something, and said to himself.

"Does red spider venom count?"

Lin Feng finally heard the result he wanted.

Sure enough, before Lin Feng came to the Beishan base, the cultivators in the Beishan base had all been injected with red spider venom, so I think the reason was here.

Red spider venom is the venom secreted by a living red spider, and after making it into serum, the effect is to resist the advanced viruses of the outside world, and tetraethyl pyrophosphate should be left in the body of the red spider, but I didn't expect the chemical to be isolated and thus injected into the body of the cultivator.

Tetraethyl pyrophosphate was used as an insecticide in the original world, but there was no such thing in the last days, so could there really be people from the original world who also crossed here?

If there really was, Lin Feng vowed to find this person. (To be continued.) )
