Yang Fan knew that this time there would be a Gu Master to come forward, and in such a situation, of course Yang Fan had to be fully prepared.

In the classics left by the Yang family, there are not many records about Gu arts. Maybe it was okay before, but in the following decades and hundreds of years, including Yang Fan's grandfather Yang Tianyi, he had never seen the appearance of the Gu Master with his own eyes.

Generations of descendants of the Yang family's medical skills, of course, will inevitably be skeptical of the existence of Gu arts. In this way, it is difficult to keep the records related to Gu art with special care.

Therefore, there are not many records related to Gu art that Yang Fan has come into contact with. However, on several common occasions, the Yang family heirs can choose to deal with it, and there are still some ways to stay.

Gu technique into the body, several different situations, Yang Fan can make targeted attempts. In fact, Yang Fan actually knew that he was not completely restrained from Gu art.

According to the few records left, Gu masters are also divided into realms. For high-level Gu masters, the Gu techniques that can be used are not only more powerful, but also more out-of-the-way, and the difficulty of wanting to treat them is also extremely high. For example, the legend is actually the most popular*. Because of its special effect, it is used by the world to warn men not to be negative about women in the Yunnan-Guizhou region, so * is the most widely spread.

But in reality, * is not one of the most common Gu poisons. The difficulty of its application is actually quite high. Yang Fan could easily treat the two Gu poisons on Xiao Chenghu and Song Yi, but according to the records left by the Yang family, it should have exceeded the scope that Yang Fan could control.

In addition to *, there are also several mixed Gu techniques, which Yang Fan has not been able to cure for the time being. And according to the records left by the Yang family, *This level is not the highest level of Gu art.

The two Gu techniques on Xiao Chenghu and Song Yi had no problem with Yang Fan. Yang Fan also speculated from this that the Gu Master of Poison Wind Valley should not be too high.

Otherwise, if the Gu Master realm of Poison Wind Valley is higher. Wouldn't it be better to directly dispatch a higher-level Gu poison? Why did Yang Fan be given a chance to save people twice.

Yang Fan actually didn't know until now, the two Gu poisons were actually not caused by one person.

The actual situation is that the existence of the Gu Master is even rarer than Yang Fan imagined. From simply playing with bugs, to playing with the toxins of the five poisons, and then to cultivating Gu poisons, it is definitely a rather long stage.

Just like the reason why martial arts have been lost, the problem that can be solved with a single * is indeed not to spend a lifetime of energy researching Gu arts. In such a situation, Gu art is actually on the verge of being lost.

There are very few descendants who have been in contact with Gu art since they were children. A large part of them will also lose the opportunity to learn Gu art because of their talent, and eventually they can only change careers to become an ordinary Miao doctor.

And even if there is a gifted person, because the inheritance is severed, the achievements they want to achieve are also limited.

The reason why the last Gu master was killed by Poison Wind Valley was because Poison Wind Valley thought that Gu Master's Gu technique was too simple. Every day he bragged about how powerful his Gu skills were, and he was very radical in wanting to gain a higher status in Poison Wind Valley. As a result, her proud Gu technique was so easily cracked by a hairy boy.

In fact, it was not simply because the Gu Master's Gu technique was cracked, but more because she had offended too many people because she was too arrogant before. Poison Wind Valley felt that she was useless, so he simply dealt with the matter. Out of sight, out of mind.

But the actual situation is that even this time the new Gu Master, none of the Gu Masters are necessarily stronger than the previous one.

It's just that the two of them are cultivating, not the same vein of Gu art.

Yang Fan didn't know this, but in the final analysis, since he was using a low-level Gu poison, his ability must not be enough. In this way, Yang Fan will not be too worried.

And the inheritance of the Gu Master's lineage, in fact, the biggest advantage lies in its weirdness. can do a silent Gu, and ordinary people can't detect it at all. It can remotely control the Gu worms in the target's body from a long distance. However, these Gu worms are very hidden, and often even modern medical methods may not be able to identify them.

In fact, in the early years, there were still cases where Gu worms were too large, but since X-ray, B-ultrasound and other detection methods have gradually matured, Gu poisons that are too easy to find have also begun to be eliminated.

That's right, even if it is discovered, it is difficult for modern medical techniques to remove it all. Even if it seems to be cleaned up through surgery, after coming down from the operating table, all kinds of Gu worms will breed again.

But because he didn't want to cause panic among ordinary people, the Gu Master eliminated those Gu poisons whose symptoms were too obvious. To put it simply, the Gu Master industry is indeed the most suitable to exist in the dark. Otherwise, people will come to the door with guns, and the Gu master really has no way at all.

The advantage of the Gu Master is that it is weird. In fact, the combat effectiveness is not nothing, but in short, it is not too strong.

And in the final analysis, the Gu Master's close-range combat methods are generally only two styles. Either it's poison or it's a worm.

And this ability is also related to the realm of the Gu Master. In the final analysis, a Gu master who can only use the kind of Gu technique on Song Yi's body is not much stronger in melee combat.

Deal with ordinary people, come and pounce as much as you want. But Yang Fan does have a means to crack it here.

Needless to say, a snuffbox Yang Fan can already ignore most of the poison techniques.

As for poisonous insects, in the final analysis, they are also insects. As long as there is a strong enough insect repellent, there is generally no problem. A high-level Gu Master may cultivate poisonous insects that are immune to general deworming methods, but a low-level Gu Master does not have such an ability.

Yang Fan spilled a bottle of pale red liquid, which was originally the blood of an anteater added to some antidote herbs such as snakeberries. It was supposed to have a strong repellent effect on most low-level poisonous insects. But this time, those poisonous insects didn't react much and continued to swarm over.

The Gu master on the opposite side couldn't help but sneer: "My Cangshan old man's Gu worm, how can it be dealt with with by casual insect repellent methods?!

Just when the old man Cangshan couldn't help but show a crazy smile, Yang Fan took out another thing from the package. And after seeing clearly what Yang Fan took out, the old man Cangshan's face immediately changed.

An ordinary flashlight is turned on, but all the poisonous insects irradiated by the flashlight quickly dissipate like a tide.
