In the quiet mountains and forests, Chen Youdao was wearing a patchwork of clothes, carrying a dilapidated clay pot in his hand, several small gourds hanging from his waist, and a large clay pot behind his back.

Chen Youdao stayed by the big cat's side for two days, and the big cat recovered, and when the big cat recovered, Chen Youdao took the big cat all over the mountains to look for poisonous insects, and he has been wandering around this mountain forest for more than a month.

Gu refining is not just any kind of bug, you have to choose some bugs with aura, and even all kinds of strange insects, in order to refine high-quality Gu worms.

Some powerful Gu insects even require some strange insects to refine, and these strange insects often have all kinds of magical abilities, even if they are advanced in cultivation, they don't dare to provoke them easily.

Tiannan Prefecture has high mountains and dense forests, and there has never been a shortage of poisonous insects and beasts, but Chen Youdao did not dare to provoke powerful poisonous insects, and only dared to choose some weak poisonous insects to start, such as common centipedes, poisonous spiders, toads and the like.

These days, he has been following the methods on the "Five Gu Secret Records", constantly capturing all kinds of poisons and putting them into clay pots to refine Gu, but he doesn't know if it's the wrong way or lack of experience, and the final outcome is that all the poisonous insects in a clay pot are dead.

Getting such a result would be devastating for Chen Youdao, but he had to continue, otherwise in a short period of time, he could only rely entirely on the protection of the big cat.

But the big cat is not his pet, but a heavenly person with his own thoughts, he is really worried, the big cat abandoned him that day, he really has no sense of security at all now, he can only continue to refine Gu, in the hope of getting a little means to save his life.

Today he finally collected the poisonous insects of Gu refining again, and was about to find a place to wait quietly for the results, in fact, he didn't have hope for this Gu refining, because the previous Gu refining failed, he couldn't even find the reason for the failure, this time he was just doing his best to obey the fate of heaven.

Chen Youdao found a low cliff that could block the rain, and placed the clay pot on his back, and then poured the poisonous insects in the small gourd on his waist into the clay pot in turn.

In this deep mountain and old forest, he, an ordinary person who didn't have any experience in surviving in the wild, asked him to go wherever to get the utensils used in refining Gu, so he carried these two clay pots with him wherever he went.

Gu refining in the world is generally to starve poisonous insects for a few days, and then put the poisonous insects into the utensils used for Gu refining, and the poisonous insects that have been hungry for a few days will naturally be driven by instinct to devour other poisonous insects as food.

The poisonous insects used in Gu refining are all carefully selected, so each poisonous insect is extremely poisonous, and the poisonous insects that can survive in the end gather all kinds of strange poisons in one, and they must be the king of poisonous insects, which is the so-called Gu.

However, this is just the most common Gu worm, and there is not much to praise except that it is extremely poisonous.

After all, in the world, everyone is an ordinary person, don't say anything highly poisonous, even ordinary poison can kill people.

But in the cultivation world, it is different, in the cultivation of people have all kinds of protective means, just a simple protective spell, with only a single poison, it is difficult to hurt the opponent.

Not to mention the disciples from the big faction, there may be how many magic weapons there are on their bodies, ordinary Gu worms can't get close to their bodies at all, what is the use of this kind of Gu worms.

There are a total of five kinds of strange Gu on the "Five Gu Secret Record", which are the Five Fire Gu, the Black Nightmare Gu, the Heart Devouring Gu, the Mayfly Gu, and the Flesh Gu.

The Five Fire Gu can only be refined by looking for five kinds of strange insects that are born with fire attributes, while the Black Nightmare Gu needs a strange insect born in the corpse pile, this strange insect is born with a yin poison and can hurt people invisibly.

The Heart Devouring Gu feeds on the flesh and blood of living beings, but fortunately, it doesn't need to use any strange insects, as long as there is a corresponding cultivation method, it can be refined, and the flesh and blood Gu is made of several kinds of ferocious insects, and there is not an inch left in the place where it passes.

As far as Chen Youdao learned about the Gu arts, most of the Gu worms are mainly Yin people, and there are few Gu techniques that can face people head-on, and the five kinds of Gu worms on the "Five Gu Secret Records" are only flesh and blood Gu that can face the enemy.

However, although the flesh and blood Gu can be very hard and steel, it is to win by quantity, and use the overwhelming Gu worms to suppress the enemy, although the power is great, but the loss is even more distressing, so Chen Youdao does not plan to refine the flesh and blood Gu.

And the mayfly Gu is the most peculiar, because the mayfly dies in the twilight of life, but the requirement for refining the mayfly Gu is indeed to find a mayfly that has lived for a day and a night as a raw material, Chen Youdao felt that one head and two big were when he saw it.

And even if Chen Youdao encounters these strange insects, with his current ability, he doesn't have the ability to catch them, among the five strange Gus, there is only the Heart Devouring Gu, and it can also be refined with conventional poisonous insects, these days, Chen Youdao has been trying to refine the Heart Devouring Gu.

The Heart Devouring Gu was only a few millimeters small, and it was good at penetrating true qi, once it entered the human body, it would go straight to the heart along the blood vessels, gnawing at the enemy's heart, and it could kill people in an instant.

And if you want to refine the Heart Devouring Gu, you not only need several poisonous insects, but also need a set of strange refining techniques, just like alchemy, refining the Gu worms smaller than a grain of rice, otherwise the Gu worms are too big, and they have long been discovered by the enemy.

As Chen Youdao threw the poisonous insect into the big clay pot, he became a little nervous, his first few Gu refining failures were actually not nothing, he still had some ideas of his own.

The conventional method of refining Gu is generally to win by quantity, using a large amount of manpower to search and even cultivate various poisonous insects by yourself, a large number of refining Gu insects, as long as they can survive a pair, they can be cultivated and expanded, and then multiply in large quantities.

But Chen Youdao is different, he did it all by himself from collecting poisonous insects to refining Gu insects, he didn't have the manpower and material resources at all, he couldn't afford that time, he still regarded Gu art as too simple.

Therefore, this time, when he was refining Gu worms, he picked some herbs according to the experience he had summed up and the knowledge in the "Initial Solution of Medicinal Herbs", and planned to put them into the clay pot together to increase the success rate of Gu worms.

However, among the Gu techniques that Chen Youdao obtained, there was no such way of refining Gu, so he didn't think of it at first, until he spent a lot of time and failed a few times, he thought of this method.

In fact, Chen Youdao didn't know whether his idea was useful or not, he just tried it with the idea of having dates and not hitting a shot.

Chen Youdao put the herbs he collected into the clay pot, and then sealed the mouth of the clay pot, and then sealed the ten fingers of both hands, and the faint true qi wrapped the clay pot, which is a spell that urges poisonous insects to fight each other is extremely simple, Chen Youdao can use it after practicing a few times.

However, Chen Youdao's true qi was weak, and with just a simple spell, he consumed almost half of the true qi of Buddhism in his body.

After a while, all kinds of strange cries sounded in the clay pot, this was the poisonous insects began to devour each other, Chen Youdao did not dare to be careless, and hurriedly gritted his teeth and continued to seal, squeezing out all the true qi in his body before casting the last spell.

Gu refining is not simply a matter of letting Gu worms devour each other, but also requires a variety of supporting spells to catalyze Gu worms into insect chrysalis, and after at least one metamorphosis, it can be considered a successful refining.

At this time, the true qi in Chen Youdao's body had been exhausted, and he hurriedly did it on the ground and began to recover his true qi.

Half an hour later, Chen Youdao woke up from the meditation, and there was no sound in the clay pot at this time, but Chen Youdao used a spell to perceive, but found that there was still a breath in it, Chen Youdao was overjoyed, and he knew that this time it might be successful.

Chen Youdao hurriedly opened the clay pot with a branch, and then ran away, a strange fishy smell came out, this is the poisonous gas left by the poisonous insects, if ordinary people inhale this poisonous gas, I am afraid that if there is no medicine stone to treat it for a while, it will bleed to death.

Even today's Chen Youdao does not dare to be contaminated with this poisonous gas, although his cultivation can last for a moment and a half longer than ordinary people, but the ending is also a dead word.

Fortunately, the big cat on the side has long been accustomed to this, and with a wave of the cat's paw, a demonic wind emerges out of thin air, blowing away the poisonous gas in the clay pot.

"Cat Brother 666!"

Chen Youdaohao shamelessly patted the big cat's ass, and then ran to the clay pot, when he saw the pupa in the clay pot, his eyes revealed a happy look.

Because the appearance of the insect chrysalis represented the success of his Gu refining this time, he hurriedly stretched out his index finger and hesitated for a while, finding that he still didn't have the courage, he opened a hole for himself, and he walked to the big cat with a flattering smile.

"Brother Cat, you make a small opening on your little brother's finger. ”

The big cat looked at Chen Youdao with an arrogant expression, as if to say Do you say sand sculpture? However, the big cat did not refuse Chen Youdao's request, but showed his sharp claws and cut Chen Youdao's wrist.

"Brother Cat, you've drawn the wrong place!"

Looking at the bleeding wrist, Chen Youdao didn't dare to delay, quickly ran to the clay pot, and dripped his own blood, and then let the big cat lick his wound with a face and help him stop the bleeding and heal.
