Feeling the speed at which Mu Chen absorbed the aura, the old man in charge of guarding the Xuanwu Pond was shocked in his heart, and stood up from the futon, his face frightened and disbelieving.

Such a majesty is not much more than the average Jindan in the later stage of Jindan's promotion to the pinnacle of Jindan, and the momentum of the breakthrough of the two of Fire Spirit and Lingyun is less than one-tenth of that of Mu Chen.

Genius is not enough to describe wood dust, maybe the word demon can match wood dust.

The old man instantly sent the news in the Xuanwu Pool to the city lord for his decision.

The city lord was stunned for a moment, and then he looked at the wood dust in the Xuanwu Pond with a surprised face, can he destroy the Demon Spring?

"Pay close attention, always be ready to add materials, and add what kind of wood dust is needed below the fourth order. ”

"Yes, Lord. ”

The lord of the country arranged the isolation formation, quietly left, and continued to guide the fire spirit and spirit rhyme.

Xuanwu City's discovery of Mu Chen, a peerless genius, will make a great contribution to Xuanwu Kingdom's master, and the materials for condensing the third doppelganger will be just around the corner.

The city lord of Xuanwu picked up the fragrant tea in his hand, savored it, and from time to time put his eyes on the wood dust in the Xuanwu Pool.

In Taixing City, Mu Mian and Yu Rou prayed for Mu Chen's blessing and blessed it with a successful breakthrough.

Ye Lao rested, did not solve doubts, did not answer doubts, did not cultivate, looked at the direction of Xuanwu Pond, and looked forward to Mu Chen coming out and soaring into the sky.

From time to time, the Lord of Canghai Mansion looked in the direction of Xuanwu Pond, waiting for the proud son of the human race to appear.

Muchen is a veritable first day since the establishment of Canghai Academy, and this breakthrough must be to break the cocoon into a butterfly and turn into a dragon.

It was a huge watershed between the foundation and the knot.

Don't look at Mu Chen, he can cross the ranks, change to ordinary students, monks, and can't cross this chasm.

In the Xuanwu Pool, Mu Chen recited the breakthrough formula, only feeling that the soul was ethereal, quiet and refreshing, and countless mysteries poured into Mu Chen's mind like the mystical sound of heaven and earth, for him to understand the mysteries of Jindan and the transformation of his soul.

Mu Chen suddenly sank into it and fell into an epiphany.

At this moment, some knowledge that is usually incomprehensible suddenly opens up and draws inferences from others.

With the continuous absorption of aura, the color of its appearance changes faintly, the size of the abutment slowly grows, and some cumbersome inscriptions appear on the body surface, as if carrying special powers.

The breath of the divine beast on the foundation platform Optimus Prime gradually strengthened, more vivid, the eyes were about to be opened, and the mysterious sounds of the dragon roar and phoenix roar resounded in the foundation platform, removing the impurities of the foundation and improving the quality.

With the infusion of spiritual energy, the dantian is expanding at an extremely fast rate, and the spiritual lake is also expanding rapidly.

The meridians, muscles, bones, flesh and blood have become thicker, tougher, and stronger as the aura has been washed over and over again.

The Seven Spirit Beads and Mu Chen have not yet raised them to a high-level magic weapon, and at this moment, they are living in the Spirit Lake, greedily absorbing the spiritual energy and strengthening themselves, and the idle magic weapon next to the Seven Spirit Beads is also devouring the spiritual energy.

Everything is moving in a good direction.

Generally speaking, as long as you run in order according to the formula, have enough perception, have sufficient aura, and have no external interference, you can break through.

The mysterious aura of the wood dust breakthrough was slightly helpful to the old man who guarded the Xuanwu Pool, and the old man closed his eyes and felt carefully.

The spirit of the turtle poured into Mu Chen's body, and was directly purified by the painter's system, turning into a special force to slowly nourish Mu Chen's body.

For the fire spirit, Lingyun and other unbearable pain and extremely test of willpower, the spirit of the turtle is not a big problem for Mu Chen.

Seven days went by in a flash.

The wood dust is like a sculpture, motionless in the Xuanwu Pool, but the aura absorbed has not decreased, and even slowly increased over time.

There was a strange sound in the dantian, driving Mu Chen out of the epiphany, and Mu Chen probed into his spiritual sense to investigate the situation:

The golden intent building abutment in the center seems to have reached a certain limit of the aura absorbed, and the thirteen golden pills in the body exude a noble aura, carrying out the entire golden intent building abutment, and the golden intent roots at the bottom poured into the remaining four abutments, and after a while, the first layer of the four abutments slowly condensed a purple pill.

Mu Chen was puzzled by this situation.

According to the explanation of Niu Er and others: reciting mantras and gathering aura, a golden pill the size of a peach pit will condense in the center of the dantian and be linked with the four abutments to form a whole.

Four stations nourish one dan, one dan feeds back four stations, why does purple pill appear in its own four foundations?

Mu Chen asked the painter system, and spent all the aura in the dantian to know the answer:

This is the exclusive breakthrough method of the thirteen-layer Heavenly Dao foundation:

The Dan of Jinyi is the sky, the Dan of the Purple Meaning is the earth, and between the heaven and the earth, the evolution and creation, and the achievement of its own Dan, so that the Jindan Fangcheng and the longevity are five hundred.

Zi Dan appeared, and the speed at which Mu Chen's spiritual energy was absorbed was even faster, and a whirlpool appeared in Xuanwu Pool, and the spiritual energy frantically poured into Mu Chen's body.

After a day's effort, the four purple pills condensed out, and the momentum of the wood dust increased by a bit, and then the purple pills on the second layer of the four foundations slowly condensed.

Thirteen days later, the four abutments in the Muchen Dantian each condensed thirteen purple pills, and the momentum of the wood dust had not yet broken through the golden pill, but it was already almost the same as the Heavenly Dao Golden Pills such as Fire Spirit and Lingyun.

Suddenly, a yellow-colored turtle spirit swam in the Xuanwu Pool, entering Mu Chen's body and sea of knowledge at an extremely fast speed.

The old man guarding Xuanwu Pond was startled, and he just wanted to stop it, but it was too late.

The Tyrant Turtle Resentful Spirit actually escaped from under the Spirit's Eye, and now the wood dust is in danger......

The seventh-order demon beast, with the divine beast: Xuanwu bloodline, unfathomable strength, was killed more than 10,000 years ago, extracted its soul, and took the seventh-order spiritual eye to suppress it in the Xuanwu Pool of the Xuanwu Kingdom.

The Spiritual Eye can help people break through, the spirit of the turtle can help people condense visions, it is a good intention, and it is the foundation of the Xuanwu Kingdom, but the longer it is suppressed, the deeper the resentment of the spirit of the turtle, and finally the spirit of the turtle is achieved.

The first appearance of the Tyrant Turtle Resentful Spirit showed the fourth-order strength, obliterating the students who entered the Xuanwu Pool that year and taking away the house.

The Lord of Xuanwu was furious when he learned about this, and personally took action to wipe out the resentful spirit of the overlord turtle, but the life of the student was irretrievable.

A month ago, the fire spirit and the spirit rhyme entered the Xuanwu Pool, and the lord of the country had just killed a tyrant turtle resentful spirit, so this time Mu Chen entered the Xuanwu Pond and did not investigate the Xuanwu Pool.

Didn't think of a mistake, and directly put the wood dust in danger.

Mu Chen's sea of consciousness was full of resentment, anger, and unwillingness, and his soul seemed to be infected with a trace of infection, and his eyes were scarlet.

The resigned spirit of the overlord turtle recovered its body, and wanted to devour the soul of wood dust, and a golden bead haunted it, captured the resentful spirit of the tyrant turtle, and refined it into a turtle inscription in the golden bead, and the shape of the overlord turtle on it circulated, but the whole body was dark and the eyes were scarlet.
