Mu Chen's promotion to the Heavenly Dao Yuan Infant requires a special breakthrough formula. The special formula can only be obtained by completing the tasks of the artist system.

Before the fire spirit left, although he left a mantra for his promotion to the Thirteen Tribulation Heavenly Dao Yuan Infant, it was not suitable for Mu Chen. After all, the fire spirit is the heavenly fire spirit root, and the wood dust spirit root is mixed.

The task given by the painter system is very simple: help 100 monks to be promoted to the realm of the primordial infant.

Mu Chen, who asked the artist system before March to take this task.

When the teacher was lecturing during the distraction period, Mu Chen once walked out of the academy and found the monk in Qingfeng City who could not break through to the Yuan Infant, and used the Fourth Order of All Beings to engrave a Yuan Infant in his dantian to help him break through to the Yuan Infant.

It is precisely because of this reason that Mu Chen has no time and no energy, and he is a pure spiritual root for Niu Er, Shui Meng and others.

Wood dust has already been obtained, for this day.

In order to ensure the success of the first step, Mu Chen crossed his knees on the ground, and repeated the refining method of the Rongze Heaven and Earth Bridge in his mind, looking for the shortcomings and making up for them.

The three doppelgangers also threw away anything, and concentrated on deducing the refining method to ensure that there were no loopholes, after all, there was only one chance for wood dust.

The refining method of the Tiandi Bridge was once in the refining room where Hu Lao was, and he had a month of enlightenment and insight into seven, seven, eight, and eight, and at this moment, he was checking and filling in the gaps.

At six hours, Mu Chen opened his eyes, and in his heart, he had eighty percent confidence in the refining of the Rongze Heaven and Earth Bridge.

Mu Chen took out the green ink tripod, took out the material, and began to warm the tripod and quench the material.

Sensing the materials taken out of the wood dust, the dryads, and the space debris spirituality, I was a little surprised.

Such a precious material, Fang Wen took it out, and the two of them did not have the slightest doubt, and it was natural. But how could it be possible for Mu Chen, the existence of a golden pill stage, and could it be that Mu Chen's desire to refine a sixth-order spirit treasure?

Quenching materials, from easy to difficult, wood dust orderly refining. The aura continued to be output and absorbed, but no chronograph appeared above the head of the wood dust.

This is not a test of potential.

For this assessment, Mu Chen can only shorten the refining time as much as possible, and the power of the two Yuan Infant Stage can bless himself.

After the eight hours, when Niu Er's body gradually trembled, the wood dust will be melted into the Heaven and Earth Bridge body to complete the refining, and the next thing is to give the spirit.

Soul Empowerment Technique: Under the Spirit of the Sea, countless silver and golden points of light are integrated into this magic weapon, and gradually gather a touch of spirituality.

The Melting Heaven and Earth Bridge was enough to devour the golden and silver points of light of the four hours, and only then did it stop unsatisfied, condensing a small piece of wood dust, like a primordial infant of wood dust.

Mu Chen can clearly feel the connection between this spirituality and himself, and the water and milk are blended. One big and one small, two fingers touched, and Mu Chen received the information of this Dao Spirit Treasure.

Accommodating and transforming the power of rules, and finally turning them into one's own. Refining and purifying aura, expanding dantian, and so on. Feeling the power of the Rongze Heaven and Earth Bridge, Mu Chen smiled and put it into the storage ring.

At this time, it is not the best time for wood dust to break through. The essence of the Jindan period of wood dust can still be increased, but it has not yet broken through to the extreme of Jindan. And the sea of golden aura wandering in the dantian can also be compressed.

Mu Chen did not rest, and promoted the natal half-spirit treasure to the spirit treasure one by one. When everything is ready, Mu Chen crossed his knees and absorbed the aura.

The feedback of the seven spirit treasures in succession made the Dantian of Wood Dust expand by one-fifth. The meridians are more tenacious. The flesh and blood are tighter, and the vitality is more intense.

The golden ocean, under the oppression of the power of the wood dust soul, gradually compressed. Two water droplets are transformed into one, and the quality of the water changes slightly. In a short period of time, half of the area is vacated in the dantian of wood dust.

The wood dust turned into a bottomless black hole, swallowing aura. When the Jinyi aura returned to its full value, the wood dust was compressed again.

Once......

Twice......

Three times......

After eight times, the aura of golden intent is transformed into the aura of purple gold, and the golden pill of wood dust is transformed into the same color. The quality has changed drastically, and it is nearly ten times stronger than the previous Golden Spiritual Qi.

Every drop weighs like a thousand pounds, and contains terrifying power. Such a quality of aura, in the infancy, will not be comprehended and condensed by monks.

Use this aura to release a spell attack, which can definitely amplify the power of the spell to the extreme.

Suddenly, the aura of purple and gold color merged into the golden intent pedestal high in the dantian at an extremely fast speed, and the four purple intent pedestals around the golden pill.

The three breaths, the quantity is comparable to the vast aura within the Heavenly Dao Yuan Infant Peak Cultivator's Dantian, and the quality is comparable to the high-quality aura in the distraction period, that is, it dissipates and is all integrated into the foundation building platform.

Mu Chen felt a touch of weakness, and turned into an endless black hole again.

The new influx of aura was automatically compressed by the dantian and the golden pill and transformed into the aura of purple gold. It took eight hours to fill the wood dust dantian.

As soon as it returned to its full value, it dissipated and sank into the foundation again.

The golden will build the abutment gradually to the color of purple gold, the background is more profound, and a special and hidden power is gradually being nurtured;

The spirituality of space debris, the act of dissipating aura from wood dust, it is impossible to determine whether it is a foul act. Scattered into the foundation of the platform, Muchen may be the first person in ancient and modern times.

In the end, it was decided that Mu Chen did not commit a foul, but it was just a way to enhance the foundation in another way.

At this point, eight people and two demon beasts entered the secret realm for one day.

In addition to Niu Er, the other nine figures still sank into it, unable to extricate themselves, and their breath steadily improved.

Niu Er looked struggling, his body trembling slightly, and he was struggling. But still, he kept absorbing the aura, and he didn't want to give up, and he had already absorbed it to the full value within the dantian. You can only absorb the aura, transform it into special power, and practice the Seven Turns Spirit Body Duel.

"Niu Er, try to compress the aura and compress it with the power of the soul. Compress to the extreme?Try to escape into the foundation platform. ”

The wood dust transmits the sound for Niu Er, condenses and transmits the image of Niu Er's own dantian.

Looking at the aura in the Muchen dantian, Niu Er almost didn't go mad. What is this? Can this be the aura condensed during the Jindan period? And why don't you devour your own aura?

However, compressing the aura seems to be the most suitable solution for the time being.

Niu Er began to compress the spiritual energy, looking for a way for the spiritual energy to escape into the abutment and improve the abutment......

The aura in the wood dust dantian dissipated, and part of the consciousness absorbed the aura, and part of the consciousness consulted the classics left by the alchemist.

In eight hours, the wood dust dantian returned to a full state, but it sank into the foundation again at an extremely fast speed.

This was repeated nine times, and three days passed in a flash.
