Yang Fan is not alarmist, this poison before can indeed achieve a similar effect.

Even the effect of the acupuncture is absolutely limited, and the effect of the acupuncture is to remove toxins. And this time, the essence of the toxin is actually out of the ordinary toxin components. Already a microorganism with a special effect.

Ziying is almost useless for this kind of effect, even the Lying Cow Needle, although Yang Fan has not tried it, it must be ineffective.

There is a term that is actually often heard now, and that is "probiotics".

To put it simply, the human body is not absolutely pure. In addition to the massive amount of metabolites that have not had time to be excreted, there are many bacteria and microorganisms that are beneficial to the human body.

The Shadow Needle can identify most of the toxin components, which is actually quite good. And the time when the Shadow Needle was studied was definitely hundreds of years ago. At that time, what level of understanding of microorganisms could Chinese medicine achieve?

It can identify most of the toxin components, even the new toxin newly developed by Poison Wind Valley for use on Xiao Yuran and others, and the Ziying Needle can identify and eliminate it. Yang Fan couldn't help but be shocked by the effect of the Shadow Needle.

It also requires an acupuncture technique that can achieve the level of identifying friend and foe, distinguishing probiotics in the body and microorganisms harmful to the human body. It's really a bit of a strong man's difficulty.

Therefore, for Gu Technique, Yang Fan needs to use a special method to expel him. And this time when it comes to microorganisms that devour flesh and blood, Yang Fan also knows that it is difficult to have a similar effect with the Ziying Needle or something.

The Lying Cow Needle may be able to replenish the lost flesh and blood in time. But at the end of the day, the Crouching Cow Needle will always pass. If you don't cut off your wrist in time, you have to try it with a lying cow needle. When the time of action is up, I am afraid that it is not possible to solve the problem with one hand at all.

If it weren't for the fact that there was really no other way, how could Yang Fan do such a cruel act.

Yang Fan quickly bandaged this person. The right hand was abolished, and there would be no career to speak of in the future. It is a lying cow needle, which can restore ordinary injuries, but it is impossible to recover a large family with a broken arm. In particular, the person's right hand was still rapidly dissolving when it fell to the ground.

With the Lin family here, it can guarantee the superiority of this person's life for a lifetime. But in the final analysis, it can be regarded as a lifetime completely ruined in the hands of Poison Wind Valley. For Poison Wind Valley, the feeling that everyone is hating the same enemy has reached an extremely high level.

Captain Liang frowned, and after a long time, he asked Yang Fan. "And how do you get over now?"

I heard that the effect of this poison was similar to that of the bone dispersion in "The Legend of the Deer and Ding", and I watched a brother's arm gradually dissolve. These people are all masters who have seen the world, but before, they couldn't help but take a step back.

Near the door, in fact, it has become a vacuum. The nearest people kept a distance of at least three meters.

Even Yang Fan actually took a step back consciously. It's really this kind of thing, it's really too dangerous.

When Captain Liang asked, Yang Fan couldn't help frowning. But after a pause, he responded quickly. "Let the logistics mobilize a bag of caustic soda. By the way, and water. ”

Toxins are complicated to say. In fact, it is also simple in the end.

In the final analysis, it is a combination or reaction with the components in the human body. So it will lead to some changes in the body.

Take, for example, the most common so-called gas poisoning, the toxic gas CO carbon monoxide. In the final analysis, carbon monoxide gas enters the body and binds to hemoglobin. In this case, even if oxygen is in the body, the target hemoglobin has already bound to carbon monoxide, so it cannot absorb oxygen for the time being.

The end result is suffocation.

Other toxins, in the final analysis, are similar to those that react with some of the body's own components, or as in the case of carbon monoxide, simply combined, making it difficult for the body to perform certain functions. The final manifestation is the symptoms of poisoning.

One of the most common reactions in daily life is the redox reaction.

And if you want to detoxify, you either have to reverse this process, or you have to react further to produce other substances. To put it simply, if you want to make a substance oxidize or reduce it. The fastest and widest range of toxins is actually to use strong acids or bases.

Yang Fan studied medicine and did not go to an ordinary middle school physical chemistry course at all. But these days, medical skills are often not simple medical skills. In this era, if medical skills want to be truly profound, at least the understanding of chemistry and biology must not be bad.

Although Yang Fan received traditional education at home, Yang Tianyi also taught Yang Fan very seriously in corresponding to these basic disciplines.

It is completely infeasible to detoxify with strong acids or alkalis. Strong acids and alkalis are actually strong corrosive. It is impossible to save people, and it is more likely to dissolve people into them.

But if it is not used on the human body, but in the open field in the wild, the arrangement of an ordinary poison is dissolved. Substances such as acids and bases are a very suitable situation.

If you are in an open area, you will encounter a toxin that requires a strong acid or a strong base to react. In cases where the toxicity of the product is almost certain to be very weak, it is perfectly possible to react with this material.

So before, Yang Fan also made Lin Chong make some preparations.

It's just that the layout outside is really too simple, and there is no need for such means. And if you enter the three caves, many similar reactions will bring out the gas that is still poisonous. So far, many of the materials that Yang Fan has prepared for the unexpected have not had time to use them yet.

But now, it's finally time for caustic soda to come into play.

The ingredient of caustic soda is NaOH, which is not a threat in its solid state, and is often used in the food industry. However, when dissolved in water, it becomes a corrosive solution.

Previously, the gases produced by other toxins were generally toxic. In the case of other countermeasures, the Lin family's large army did not use such means.

But this time, the toxin on the other side is actually a microbial situation. In this way, there is no risk of too many harmful gases being generated.

Yang Fan quickly completed the preparations, and a large amount of caustic soda solution was spilled out.
