Perhaps sensing that the breath of life was about to end, all of a sudden, the small blood clots of essence blood that had not yet been refined by Gu Zichen began to riot collectively, confronting each other with Gu Zichen's refining mana, and desperately drilling into Gu Zichen's body.

Gu Zichen frowned, roared, and slapped his right hand towards the dantian, and suddenly, the mana surged, instantly absorbing all the blood clots in the muscles.

The moment he absorbed all the essence of the blood droplets, Gu Zichen's ****'s body was glowing, and his muscles burst out. Gu Zichen felt as if he was hiding a beast in his body, ready to attack, ready to pounce.

"Moo!"

Gu Zichen was overjoyed in his heart, stood up suddenly, opened his mouth, and let out a sharp roar, the sound shook the four wilds, and in the dark, it seemed to carry a bull's spirit.

Gu Zichen's essence flickered, his finger pointed upward, and suddenly the small blue flag fluttered and fell into Gu Zichen's hand, and the original fiery red and shining firelight suddenly went out, and the place returned to a white scene again.

Gu Zichen suddenly turned his head, looked at the little beast Yueyue with a look of shame on his face, stepped off the high platform, and said with a bright smile: "Little Yueyue, don't you know me?"

"Squeak"

The little beast lowered its small head, stretched out its forelimbs, and pointed at Gu Zichen's **** body, not daring to take a closer look.

Gu Zichen smiled, put on his clothes, took out a futon, sat cross-legged on the ground, rested, and after completing all the mana, he suddenly released a huge bone from the storage bag and placed it in the open space in front of him.

The skeleton is about two zhang long and about half a zhang wide, like a giant thing, lying in front of Gu Zichen.

The skull of the skeleton resembles a bull's head, but there are four horns at the head of the bull, two of which are on both sides of the bull's head, about half a meter long, the horns are curved, and the tip of the horns rushes towards the tail of the ox, which is extremely sharp.

The other two horns grew above the top of the bull's head, only a few feet long, spiraling, facing the sky, and the two horns were sharp, as if dyed gold.

Four cow hooves, with sharp cow claws, are placed on their sides next to the skeleton body, as if telling the glory of the past.

This bone and the drop of essence blood that had just been refined were exactly what Gu Zichen had purchased from a merchant in Nanming City who was reselling the demon beast business for 10,000 medium-grade spirit crystals.

This demon beast is called Shenjin Xuanniu, and it has reached a realm equivalent to the early stage of the human God Refining Realm during its lifetime, and was killed by several cultivators of the God Refining Realm in Nanyu County, and sold to Gu Zichen.

If Gu Zichen wanted to practice the Fusion Yuan Gong, he had to refine the essence blood and bones of the demon beast into his body in order to enhance his combat power. Among the Rong Yuan Gong, they were divided into categories and introduced several formations to help the monks refine the essence blood and bones of the demon beasts.

The formation arranged by Gu Zichen before was the formation flag and array plate that Gu Zichen asked Xie Wenyao and his wife to help refine.

Gu Zichen recalled, let go of his divine sense, put the Divine Golden Xuanniu bone back into the storage bag, stood up suddenly, came to the edge of the magic circle again, leaned over a bulge on the half-meter high platform, and pressed it.

There was a clicking sound, but in the center of the high platform, a stone building like a stove slowly rose, the stove was about half a meter high, one zhang long and one zhang wide, and hollowed out in the middle. Directly opposite Gu Zichen, there was a square portal.

Gu Zichen leaned over to the door of the stove, took out a few pieces of fiery red ore from the storage bag, put them into the stove, and then placed a piece of medium-grade fire attribute spirit crystals on the edges of the stove before stepping to the edge of the high platform.

Gu Zichen's face was solemn, and he hurriedly took out a quaint cauldron from the storage bag and put it on the stove. The cauldron had a diameter of two zhang and a half, and it almost filled the entire high platform, and Gu Zichen could only stand at the edge of the high platform.

The cauldron is not an ordinary dark color, the round surface is engraved with bright color pictures, but after the invasion of time, only the traces of the engraving remain, and only a few parts retain some color.

Seeing that all the preparations were completed, Gu Zichen took out a small blue flag and injected mana into the flag, and in an instant, the flag no longer showed blue, but became fiery red.

Gu Zichen held the flagpole in his hand and pointed to the door of the stove, and suddenly, in the stove, the ore left by Gu Zichen spontaneously combusted without wind, and after a while, the fire was vigorous, connected into a piece, raging fire, exuding blazing flames, baking the cauldron on the stove.

Gu Zichen didn't give up, threw the small flag upward, pointed his finger, and the law in his mouth sounded, and suddenly, the fiery red light shield covered Gu Zichen inside.

After doing all this, Gu Zichen's face was full of joy, and he hurriedly took out a bag-like object from the storage bag, uncorked the bottle, and slowly poured it into the cauldron. The bag didn't seem like much, but the endless blood-colored potion flowed into the cauldron without stopping.

When the blood reached two-thirds of the cauldron, Gu Zichen stopped pouring it, re-stuffed the cork into the bottle, and carefully put it into the storage bag.

Gu Zichen walked back and forth on the edge of the high platform, as if he was extremely nervous in his heart, with a stick of incense, watching the blood boiling hot and foaming, the tension on his face was overflowing, and he hurriedly took out the bones of the Divine Golden Xuanniu from the storage bag and slowly put them into the tumbling blood water.

As soon as the bones of the Divine Golden Xuanniu entered the water, they sank under the blood and disappeared, as if they were hidden. At this time, Gu Zichen's expression calmed down, his eyes were focused, and he took out some materials from the storage bag from time to time and threw them in the cauldron every once in a while.

In a quarter of an hour or so, there was a smell of incense throughout the mask, but if you taste it carefully, you will find that there is a bloody smell hidden in the fragrance.

After Gu Zichen smelled the smell of blood, his face once again showed a nervous expression, his eyes roamed back and forth, but he no longer put materials into the cauldron in his hands.

After another five minutes like this, the fragrance in the light mask became even stronger, Gu Zichen hurriedly took off his clothes again, sat on the edge of the high platform, and was in the light mask, feeling comfortable, and some subtle objects continued to burrow into Gu Zichen's body.

However, the good times didn't last long, and after a meal, the feeling of numbness gradually replaced the feeling of comfort, and Gu Zichen's complexion slowly changed from enjoying to clenching his teeth, as if he was enduring a strange pain.

Under such patience, Gu Zichen's body slowly exuded a bright color, but from time to time, red light would flash, and the whole body had both a solemn taste and an evil aura flashing, staggered, incomprehensible.

"Moo!"

A roar, with the last despair, suddenly resounded in Gu Zichen's ears, Gu Zichen's face was overjoyed, he suddenly held back the pain in his body, stood up suddenly, flashed, and jumped into the cauldron.

As soon as Gu Zichenfu entered the cauldron, he didn't feel a trace of the bones of the Divine Golden Xuanniu at all, and the entire two-zhang long skeleton seemed to have been refined, and it was all integrated into the cauldron.

Without leaving Gu Zichen any time to think, the hot blood and the essence of the Divine Golden Xuanniu Bone seemed to have found an outlet, and in an instant, all of them poured into Gu Zichen's body.
