The Gu refining technique performed by Butterfly Fairy and Xiao Wei relied on stimulating the fighting instinct of these insects themselves, allowing them to see a glimmer of hope for the transformation of their lives, and removing their fears, so that they would not run away. There's no need for any crockpots or anything like that.

Of course, such a Gu refining method is not easy to cast. Anyone who can perform it must have a good inheritance of the way of witchcraft, and the art of refining Gu must reach a certain level of attainment. Generally, it is a monk who has been in the path of witchcraft above the Dan stage to perform this technique.

Monks in the Qi refining period and foundation building period also need to use things like clay pots and magic weapons.

This butterfly fairy, when she saw Xiao Wei perform this technique, she was shocked. He asked, "You are also a descendant of the Southern Xinjiang Witch Gu Sect, how come I have never heard of it?"

Xiao Wei said to the butterfly fairy: "The heir is not counted, but there is some relationship." ”

The butterfly fairy naturally didn't believe it, snorted, stopped talking, and secretly urged the snakes and insects that were wriggling on the ground and trees in the primeval jungle.

Among the five poisons summoned by the butterfly fairy and fighting each other, the most poisonous is the snake. According to the statistics of scientific research rankings, among the five poisons in the Chinese tradition, the most poisonous are all kinds of strange snakes. Yun Lei looked down in the air and found that among these snakes and insects, when wriggling and fighting, the most victorious ones were all kinds of twisting and twisting snakes.

The top ten most famous venomous snakes in China are the silver krait, the king cobra, the southern cobra, the original spearhead viper, the white-lipped bamboo leaf green, the white-browed viper, the gray-blue flat-tailed sea snake, the round spotted viper, the krait snake and the sharp-nosed pit viper. In this primeval jungle, there are actually quite a few.

In addition to this, there are some huge pythons, meandering and crawling. This python in the southern Xinjiang of China, although it is not too poisonous. But the size is large enough. And there is also a certain amount of antitoxicity. So with its huge size, and anti-toxic properties. You can also eat some small poisonous snakes into your stomach one by one, just like eating longevity noodles.

In southern China, there are no scorpions or centipedes that are too poisonous. Even if they bite people, most of them are poisoned by scorpions or centipedes, and they will not have to worry about death. The biggest effect of scorpion venom is that it can cause convulsions and strokes of people or other living beings, and after being bitten by centipedes, it will only be a little swollen and painful.

Therefore, among the two five poisons, scorpions and centipedes, they are gifted and have strong poison. Very few in China. Although there are many places like Oceania, it is not where southern China is located after all. In this southern Chinese Xinjiang, there are no such extremely poisonous scorpions and centipedes.

These scorpions and centipedes can only fight to defeat those insects that are not poisonous at all, such as flying ants and locusts.

Their natural predators, in addition to snakes, are also toads. The toad is a thing commonly known as a toad. If it is divided according to the category, it is a kind of frog. Therefore, some poisonous frogs are also classified as toads. The toad has rough skin on its body and is covered with large and small pimples on its back, which is very unsightly. But it is among these large and small pimples that there is a part of the sebaceous glands that can secrete highly toxic substances.

According to the body structure of the toad, the largest pair of sebaceous glands are the postauricular glands located above the eardrum on the side of the toad's head. This gland is the main site of venom secretion. The rest of the pimples have spines on them. These thorns are not all poisonous.

These sebaceous glands secrete venom and are mostly white. These venoms are the raw materials for humans to make toad cakes.

However, although these toads are also good medicine, if they are accidentally contaminated, the venom in the toad's sebaceous glands can be blinding and deadly! Its toxicity is far greater than that of ordinary snakes. The toads after these mutations in southern Xinjiang are even more violent.

Although toads are usually lazy, they are not very aggressive towards people. Therefore, there are few cases of human death due to toad venom. But who dares to bite the bumpy sebaceous glands, or provoke the toad to let the venom in the sebaceous glands secrete itself. Then there is only one dead end.

However, there is nothing that the toad itself does not eat. Whether it is a centipede, a scorpion, a locust, a flying ant, a butterfly, a dragonfly, a mosquito, a fly, a moth, or a praying mantis, as long as you dare to fly in front of the toad's eyes, you can't escape the toad's tongue and swallow it. Some toads with ferocious personalities won't even let go of their smaller counterparts as they pass by.

Among the five poisons, lizards and geckos, which could originally be classified as one large category, were the least poisonous. Although some of the venom secreted in the body of this type of creature is quite toxic to humans. It's always inevitable to be bitten for two days.

However, in the presence of snakes and toads, this mere toxicity is not enough. Not even as good as a venomous spider. It's a pity that the most suitable thing for a spider is to build a web to trap the opponent and attack from the side. There are too many weaknesses in its body structure, so it is not suitable for frontal conflict and fighting. Even some rare, venomous spiders are not suitable for fighting toads and snakes that are huge, equally venomous, or even more venomous.

Therefore, in the long entanglement and struggle, the last two Gu worms that survived were a yellow-green snake with a color like spring willow leaves. At first glance, it looks like a beautiful white-lipped bamboo. But it was huge, like a giant python.

Its shape, unlike an ordinary python, is a complete and angular diamond shape. The snake letter that spit out is even more vivid blood red. Pretty unspeakable.

The other is a huge toad as big as an ordinary person's head. And the color on the skin of this huge toad is no longer the earthy yellow color of ordinary toads. Or brown and black.

Rather, it is an extremely bright orange-red. It seems to be the color of the clouds on the horizon between day and night. But such a beautiful color, with that pimple, dense, ugly to explode bulge. And the spikes on the bulge. The feeling is not beautiful at all, but terrifying.

Within a radius of thousands of miles summoned by the Butterfly Fairy, hundreds of thousands of poisonous insects in the southern frontier, after a long time of devouring and fighting with each other, there were only these two heaven and earth alien species left. This snake and a toad have also undergone several mutations and evolutions in the process of fighting and devouring other snakes and insects.

Not to mention anything else, the yellow-green bamboo leaf green shaped like a python has undergone several molts and evolution in just a dozen hours.
