Under one person: I, Zhang Zhiwei, the arrogant Zhang.

Chapter 715: The Birth of the Gu God
The Great Gu Master laughed wildly: "Although I failed to gather all 7749 Gu-body Holy Children, it's a bit imperfect, but it doesn't have a big impact. I finally succeeded!"

"It's a pity that all the people from the Medicine Fairy Society are dead. No one can witness me taking this great step. Even you, a stinky cow nose who knows nothing, are about to die."

In his excitement, the Great Gu Master could not remain calm and had a face that looked like a mean person scratching his head.

"Just a clown!" Zhang Zhiwei sneered, with disdain in all nine pairs of eyes, and a disdainful voice came out from the mouth of the nine-headed lion:
"What can a bunch of snakes and rats do together? For such a small amount of power, you killed so many children. I will dig out your brain and see if it is a pile of dog shit?!"

The great Gu Master became angry: "How can you, mediocre people who can only practice Qi and chant scriptures, understand the great power of Gu?!"

Then, he sneered: "Killing so many children? You think it's cruel, right? In fact, it's not cruel at all. In recent years, there have been wars and chaos. Isn't the number of people killed in any war less than this? Only a few people died, what does it matter?"

The Great Gu Master became more and more excited as he spoke, and the large cocoon wrapped with black threads beneath him swelled abnormally and began to beat like a heart. An earth-shaking change was taking place in the cocoon.

Zhang Zhiwei glanced at the cocoon. The extremely violent energy he felt on the ground before was emitted from this cocoon.

At the same time, the main body had already entered the entrance of this underground space. Zhang Zhiwei no longer wanted to continue talking nonsense with the other party, and immediately urged the nine-headed lion to stop it.

But as soon as the nine-headed lion moved, there was a loud "puff" sound, and a huge vine came whistling over. The vine was as thick as a thigh and suddenly emerged from the stone wall behind the great Gu Master.

When it was pulled into the air, the vine opened its ferocious mouth like a biological tentacle, and its top split into three petals, each of which was covered with sharp teeth, biting towards the nine-headed lion.

The nine-headed lion opened its mouth and bit the tentacles that were whipping towards it, breaking them into pieces.

But then, the sound of dense stone walls cracking could be heard throughout the space, and beneath the surface of the stone walls, dense vines were twisting and dancing wildly.

They are the result of the effect of the poison on the vines, which can be considered a kind of raw Gu, and they were just planted by the master Gu master.

If an ordinary Gu Master wants to successfully inoculate a Gu, he needs to prepare the poison according to the object to be inoculated.

This process is many times more complicated than the talisman drawing method of the talisman school and it cannot be accomplished overnight. However, if one possesses the original Gu, it is a different matter.

In addition to being extremely toxic itself, the original Gu can also be converted into other Gu poisons at will.

In other words, some extremely rare and difficult to make strange Gu in the world, the original Gu can be transformed in a single thought, it is like the Tongtian Talisman in Gu magic.

The bodies of the Gu-body Holy Children contain the original Gu, and they can use all kinds of Gu poisons at will.

But the gift from fate had already been secretly marked with a price. They were made and destroyed by the original Gu.

Because the original Gu is extremely poisonous, once it appears, it will corrode the internal organs and destroy the meridians that circulate Qi, which makes the means of the Gu-body Saint Child quite simple.

Not only that, the original Gu will continue to expand like cancer cells until it dies with the host.

For example, Chen Duo in the plot always wears protective clothing when she is in the company.

The reason for this is that she needs to expel the original poison in her body that is constantly expanding like cancer cells. Only in this way can her own pressure be reduced.

If the original Gu that has been expelled does not find a host and has no Qi to nourish it, it will die in a very short time.

Therefore, Chen Duo wore protective clothing just to prevent the poison she expelled from affecting others.

Of course, as a holy child with a Gu body, Chen Duo can also suppress those primitive Gu in his body and prevent them from exploding.

Once when she went out on a mission, her protective suit was broken, so she suppressed the poison and played with a kitten for a while.

However, suppressing the original Gu all the time is not a long-term solution, because the production of the original Gu poison is not controlled by Chen Duo himself. If it is forcibly suppressed in the body all the time, it will cause it to spread in the body.

If the spread is too much, to the point where Chen Duo cannot suppress it or cannot provide for it, the original Gu will erupt.

At that time, she would be like a cancer patient, either dying from tumor rupture and organ damage, or dying from nutrients (qi) being absorbed.

This is a very unsolvable problem. It is difficult to live long if you suppress the poison. If you do not suppress the original poison and keep releasing it, you can ensure that the poison does not progress quickly.

But in this way, she will become an alien that cannot be accepted by the secular world, similar to the drought demon in mythology and legends, where no grass grows wherever she passes.

However, the great Gu Master of the Medicine Fairy Society used a method similar to vaccination to weaken the toxicity of the original Gu in the body of the Holy Child before inoculating it into his own body.

In this way, he not only mastered the original Gu, but also would not be attacked by it. He had complete meridians and could use Gu techniques and other means at will.

As for the issue of the original Gu's toxicity being reduced...

He didn't care. The important thing about the original Gu was its ability to transform into other poisons at will. Which fool would have the original Gu to poison people directly?

With just a little trickery, he could transform the original Gu into a poison several times more toxic than the original one. For example, it could not only kill the person who was poisoned, but also cause the bloodline of the poisoned person to not live past the age of 30 for generations.

And the vines in the cave at this moment were the products catalyzed by him using the primitive Gu.

Although they had just been catalyzed, the power of these vines was not small at all. Hundreds and thousands of vines lashed violently, tearing the air, leaving white marks in the air.

They bit the nine-headed lion like poisonous snakes, their attacks were as dense as rain and as powerful as thunder.

But at this moment, a blazing white light emerged from the other end of the space. In an instant, the whole room was bright, and then a deafening thunder followed.

No matter what kind of existence it is, facing Thunder directly is not a wise choice.

The vines that were whipping towards the nine-headed lion like a group of dancing snakes suddenly tightened and hugged into a ball to protect the great sorcerer.

The next moment, thunder and lightning came, turning into blazing light and roar, submerging all the vines, including the nine-headed lion.

After a moment, the white light faded, and those vines that were as tough as steel were completely destroyed by the bombardment of thunder, turning into powder and falling like black ash.

The nine-headed lion was unharmed and still standing in the same place. Next to it stood a tall and burly Taoist priest, who was Zhang Zhiwei who had rushed over.

Zhang Zhiwei stared ahead, where there was a huge stone.

The stone was emitting black smoke and was covered with spider-web-like cracks.

"Kakaka..."

The cracks were expanding, and stone chips fell in, revealing the scene inside. It was a black cocoon, the same cocoon that had been under the Great Gu Master before.

But the upper body of the Great Gu Master was no longer on the cocoon, as he had been reduced to ashes in the previous thunderstorm. Zhang Zhiwei looked at the black egg and was a little surprised. Since he came out of the mountain, thunder magic has been his invincible sword, and he rarely fails. The opponent's thing, which seemed fragile, could actually resist it.

"It used vines to resist for a while, and then quickly formed a layer of insulating stone shell on the cocoon to resist. Apart from anything else, this brain is quite useful and the reaction speed is also very fast!" Zhang Zhiwei thought to himself.

He was not afraid of the strange black egg and walked towards it leisurely.

But at this moment, there was a "dong" sound, and a heavy sound like the beating of a heart came from the black egg.

The black egg trembled violently, and two sharp claws broke out of the egg, grabbed both sides of the black egg, and tore it out violently.

A humanoid creature with wings on its back, a human-like head, and a body with obvious insect features suddenly rose up from the cave. He spread his transparent wings, hovered in the cave, and laughed:
"Everything in this world is made up of Gu. Everything can be a Gu. Your thunder is nothing in front of the Gu God!"

As he spoke, he raised his arm and used Qi to activate the primitive Gu in his body. A large amount of primitive Gu gushed out like black Qi.

He did not try to use the original Gu to directly attack Zhang Zhiwei. Although the original Gu was highly poisonous, it had not changed. Unless others did not make any defense, it would have no effect at all.

What's more, the toxicity of the original Gu in his body had been weakened once. If used alone, its power would be even lower, but the original Gu could transform into other poisons at will, just like Qi.

As the great Gu Master of the Medicine Fairy Society, he could be said to be one of the few people with the highest attainments in Gu arts in the world.

The witchcraft he knew was incomparable to that of Chen Duo in later generations. The primitive witchcraft was brought to a whole new level in his hands.

Zhang Zhiwei's previous thunder was transformed into stone skin Gu by him using the original Gu, and a layer of insulating stone shell was laid around the black egg.

And now, in just a moment, he performed several kinds of witchcraft.

In one of the witchcrafts, black Qi was integrated into the stone walls in the space, causing the stone walls to grow meridians like blood vessels. The surrounding stone walls seemed to come alive, suddenly shrinking inwards, rolling and overturning.

Zhang Zhiwei's body was filled with golden light, which expanded outwards and stretched out suddenly to block the contraction of the surrounding mountain walls.

"Boom, boom, boom..."

The sound of the violent collision was like the collapse of the sky.

The surrounding mountain walls were like waves, crashing down one after another. With such power, even a tank would have been crushed into a pile of scrap metal, but they failed to crush Zhang Zhiwei's golden light.

"Just die peacefully deep in the ground, hahahaha..."

The great Gu Master laughed wildly, and then he transformed the original Gu into a giant earthworm-like Gu worm that surrounded his body.

Under the power of this poisonous insect, the hard stone wall seemed to have turned into water. He sank into it and moved underground like a walking immortal.

"Don't even think about running away!"

A big hand suddenly reached out from behind him and grabbed half of his wings.

It was Zhang Zhiwei. He actually chiseled his way through the mountain wall and forced his way underground with his physical body, even faster than the earth-walking immortals.

"Damn it, why aren't you dead yet?!" The great Gu Master was furious and urged the original Gu to transform into the Iron Skin Gu. The black Qi turned into extremely tiny black bugs, which attached to his entire body, forming an impenetrable iron coat for him.

He punched Zhang Zhiwei on the chest with his backhand, and the collision of steel and gold made a low ringing sound like a loud bell.

This punch did not shatter Zhang Zhiwei's golden light, but it used the recoil force to quickly increase the distance.

"You little bastard, you're quite good at running. You managed to escape with a broken wing!"

Zhang Zhiwei threw away the bloody wings in his hand, and his body suddenly turned into a golden light, transforming into a drill, which spun violently, with a low humming sound of metal heard in his ears.

Zhang Zhiwei traveled quickly underground, and his speed was not much slower than on the ground.

When the great Gu Master saw it, he was immediately terrified. Although the Earth-Walking Insect Gu could move underground like an Earth-Walking Immortal, its speed was not fast and could not be compared with Zhang Zhiwei.

"I'm not as fast as him. I can't continue to sneak underground."

The great sorcerer performed the sorcery again, and the original sorcery suddenly transformed into the ghost-faced moth sorcery.

Torrents of resentment emanated from the body of the Ghost-Faced Hawk Moth, spreading and moving underground, transforming into a series of blurry faces, howling and biting towards Zhang Zhiwei, with such force that it seemed to drown out everything.

But in front of Zhang Zhiwei's golden drill, it shattered like a bubble, without causing any waves.

The distance between the two sides was still closing. The great Gu Master was shocked and used another method. The roots and rhizomes of the vegetation underground were all transformed into his living Gu. Countless vines twisted and turned into swords, spears, and halberds, stabbing towards Zhang Zhiwei.

Zhang Zhiwei did not dodge or evade, but continued to maintain the golden drill and rushed forward, smashing and tearing into pieces all the swords, spears, swords and halberds that were extended over him. Even if there were extremely hard stones above, they were all smashed by him.

However, the interception of these objects did delay his steps slightly, buying the Great Gu Master some time to reach the surface.

But half of his body was still underground. He looked at Zhang Zhiwei who had drilled through the ground with half of his face, grinning grimly:

"Little Heavenly Master, Niubizi, I am not as fast as you underground, but can you still go up to the sky?"

He crawled out of the ground with a wild laugh. The moment he came out, he used the primitive Gu to perform the legendary Gu worm, which he knew how to cultivate but had not been able to cultivate for decades - the Meteoric Body Gu.

Under the effect of the body-melting Gu, the flesh buds on his back fluttered, and the flesh and blood quickly intertwined, outlining his wings again like lines.

“Hahahaha, I’m completely omnipotent. I’m the Gu God. I’m a god. Hahahaha…”

Feeling the legendary body-melting Gu traveling through his body, the Great Gu Master laughed wildly, looking excited and ecstatic.

He flapped his wings, carried by the strong wind, and soared into the sky, arriving above the valley. He looked down at the valley engulfed in raging fire, and saw a Taoist priest with big ears and a short stature below him.

"Taoist?" He sneered, "You are just an ant, not even half as good as me!"

After saying that, he cast the original Gu and transformed those black original Gu worms into a large number of red Gu worms that could control fire, surrounding his body.

With the help of these poisonous insects, he waved his hand and flames from the sky gathered towards his hand.
