As for the method of refining Gu?

There is no in the "Taiyuan Sutra", and Yichang has not dabbled much in the Gu worm, but don't forget, in his previous life, he was also a great power that cultivated to the level of an immortal, and that insight alone is a supreme treasure.

There aren't too many of the various exercises and tricks recorded in his mind, just take out one casually, and it's enough for Shen Yi to digest it.

This time, Yichang came up with an insect control technique called "The Book of Insects".

Despite the simple name, the content inside is all-encompassing and varied, and it is an encyclopedia of insects.

Gu worms are also a type of insects, and they are naturally included.

Shen Yizhi knew that what he was going to refine this time was a very random Gu worm - Nine Poisonous Gu.

She chose a location, dug a deep pit, buried a pot-bellied and thin-mouthed pottery urn in it, and began to set up the formation with the pottery urn as the eye.

After carving the formation pattern, Shen Yizhi placed homemade spirit stones in the eyes of the formation and various nodes to activate the formation.

In an instant, the complex and mysterious formation pattern was penetrated by the aura, and it quickly disappeared after it appeared.

This formation is called the Three Dou Array, and its function is very weak, it can only attract insects and optimize the insects in the formation, but if it is used to refine Gu, it is the best.

After that, Shen Yizhi repeated the previous operation, and in the remaining eight places, he also laid out three bucket arrays. The nine three-bucket arrays are connected to each other, and they form a large three-bucket array, which is even more effective.

Each three-bucket array can attract a large number of insects, and those insects will enter the pottery urn to fight each other and devour each other until the Gu worm is born.

Nine formations will give birth to nine Gu worms, and then she will put nine Gu worms into one Weng and let them continue to fight and devour, and the Gu worm that successfully survives in the end is the Nine Poison Gu!

Nine, which is the extreme of numbers, represents infinity, which means that this Gu worm is born from countless poisonous insects.

However, because there are too many insects attracted during the refining process, and there is no certain direction, no one knows what the Gu worms that are born in the end will be like until the last moment.

Even the strength and toxicity of Gu worms cannot be determined.

The Gu worms that are refined may be very powerful, or it is possible that they will only sell cuteness.

That's why she said that this is a very random Gu worm.

After setting up the formation, she only needs to drop a drop of her own essence blood every two hours, and the rest of the time, she doesn't need to take special care of it.

But the distance between the nine formations is not short, and it will take a lot of time for her to feed the blood one by one.

Fortunately, she now has a donkey to get around.

After the feeding of spiritual food and spiritual spring, as well as the baptism of spiritual energy in the space, although this donkey has not yet been reborn, his spiritual intelligence has obviously increased a lot, and he can understand some of her simple instructions.

After riding the donkey one by one, the donkey wrote down the route, and then there was no need for Shen Yizhi to command, she only needed to sit on the donkey's back, and after arriving at the destination, she would come down and feed the Gu worm blood.

She can take the opportunity to cultivate and recover on the back of a donkey.

After all, every time it is fed is essence blood, and every drop of essence blood in the body is precious and cannot be easily lost.

It's also a shame that she has a spiritual spring, and a large number of blood-replenishing and restorative pills as a backing, otherwise she is a small qi refining cultivator, even people wouldn't dare to play like this during the foundation building period.

I just hope that her luck will be better, and the Gu worms she refines will not be too chicken.

Otherwise, I'm sorry she bled so conscientiously.

Two days have passed, and the Gu worms in the Nine Three Fighting Formations have been born.

The last step, Shen Yizhi intends to complete it in space.

Bury Weng, cloth the pregnant Gu array, and put nine Gu worms into it.

Feed a drop of sperm blood every hour.

In this way, the consumption is even greater.

Shen Yizhi frantically swallowed the spiritual spring while cultivating, and at the same time ate a large amount of blood-replenishing spiritual food, so that he could replenish the essence blood he had consumed as much as possible.

Under such rapid consumption and replenishment, a day passed, she broke through to the third layer of qi refining, and the battle between the Gu insects in the pottery urn also reached the final stage.

When she looked into it, there were only two Gu worms left inside, a purple poisonous scorpion and a crimson frog, all of which looked very difficult to mess with.

When the time for bloodletting came, she dropped a drop of blood.

This drop of blood, like a catalyst, made the battle between the last two Gu worms instantly escalate and become extremely intense.

Shen Yizhi calmly watched, waiting for the moment of Gu Cheng.

Finally, there was only one Gu worm left in the pottery urn, and to her surprise, it was the red frog that survived to the end.

However, the red frog was also scarred, lying motionless at the bottom of the Weng, and its breath was getting weaker and weaker.

You're not going to die, are you?

"The Book of Worms" only says that the nine Gu worms devour each other, and when the last one is left, the nine poisonous Gu are born naturally, but there is no mention of the current situation.

At this time, Yichang was not around, and Shen Yizhi had no one to discuss, so after thinking about it, he continued to drip blood into the pottery urn.

The essence blood fell on the red frog and was absorbed by it, and at the same time, the blood color on its body was slowly fading, revealing a jade-like whiteness, but its breath became stronger. It seems that some kind of magical metamorphosis is underway!

Just a drop of essence blood went down, and only a small part of the red skin on its body had faded, which showed that it needed more!

Shen Yizhi had no choice but to continue to bleed.

Two drops ...... Three drops ...... Four drops ......

The red color of the red frog melts like ice and snow meets sunlight, revealing a snow-white undertone, but when this change reaches the head, the speed suddenly slows down.

She offers a few drops of sperm blood to fade the color of the blood even a little.

However, things have come to this point, and it would be a loss to give up again.

It is not advisable to give up halfway, Shen Yizhi can only grit his teeth and continue to insist.

The pills and spiritual food had run out, and Shen Yizhi began to attack those elixirs that replenished blood and qi.

Straight raw food!

In the back, her face became more and more pale, and when the blood groove was almost empty, the last bit of blood on the frog's body faded and turned completely white!

The whole body is as white as jade, like a jade carving, and the two eyes are blood-colored, crystal clear, like two red gems.

Overall, it is only the size of a grape, delicate and small, quietly creeping and moving, like a jade carving.

Nine Poisonous Gu, it's done!

Shen Yizhi forced out a drop of blood from his fingertips, making him recognize the master and complete the last step.

When she sensed the establishment of a weak but steady connection with the Nine Poison Gu, she fainted with relief.

The Nine Poison Gu jumped out of the pottery urn, lay on the edge, looked at Shen Yizhi for a while, jumped to her chest, and lay still.

Shen Yizhi woke up again, and it was already the next day.

There is still a feeling of weakness in the body that has been hollowed out, after all, after losing so much essence and blood, it is not something that can be recovered in a moment.

But fortunately, it didn't hurt much.

Yesterday, she fainted before she had time to check the situation of the Nine Poison Gu, and now when she looked at it, she couldn't help but be surprised.
