When Sun Yi'an opened his eyes again, it was already three days later.

He exhaled a breath of turbid air and released his divine sense to probe the situation in his body.

At this time, above Sun Yi'an's dantian, two black and white filaments formed a circle, slowly rotating, and the five-colored spiritual power under it was almost condensed into a liquid state.

The physical spiritual power in his dantian had reached the most extreme state of the Qi refining period, and he could no longer increase it even the slightest!

Sun Yi'an's divine consciousness withdrew from his body, and according to the record of the formation catalogue presented by Elder Lu, he arranged a spiritual array like that of the alchemy that day.

These spirit stones were naturally obtained from more than a dozen demon cultivators who had fallen into his hands.

The gold belt of murder and arson, it has been like this since ancient times!

When these things were done, it was evening.

Sun Yi'an did not enter the formation, but got up and thoroughly cleaned the small courtyard from the inside out, and played with Lang Xiao for a while.

When night had completely fallen, he burned incense and bathed, entered the formation barefoot, and began pranayama meditation.

Oriental Weixi.

Sun Yi'an, who had been meditating and pranayama all night, suddenly shook with one hand, and seven spirit pills floated on his chest from the jade box, and with another raise of his hand, the thousands of spirit stones on the ground began to shake slightly, emitting a warm and soft light.

At this time, he has no joy or sorrow, no anger or anger. The mind and spiritual power are in the best condition.

In order to prepare for this breakthrough, he took out all the spirit stones and pills.

It's a matter of success or failure!

Suddenly, Sun Yi'an opened his mouth, and seven Peiling pills rushed in, and he swallowed them at the same time!

At this time, if there are outsiders present, they will definitely be shocked. For a cultivator in the normal Qi refining period, every time he swallows a pill, he needs to meditate and refine for several days, and if he swallows seven pills at a time, he will die because he can't suppress the spiritual power contained in this pill!

Sun Yi'an naturally knew about this, but the original spiritual power in his body was several times thicker than that of ordinary monks, and at this time, the amount of spiritual power required to break through the foundation building period was even larger, even if there were seven more, he would swallow them without hesitation!

Rumble!

As soon as the elixir prescription entered his body, it turned into a majestic spiritual power raging in his body.

Right now!

The spiritual power in Sun Yi'an's dantian spun rapidly, turning into a five-colored vortex, attracting the surging spiritual power released by the Pei Ling Pill into the dantian.

In the formation that had already been arranged, thousands of spirit stones trembled and floated at the same time, and streams of five-colored spiritual power floated out of the spirit stones like silk, rolling and submerging Sun Yi'an's figure in it.

The vortex in the dantian rotated even faster, and it was no longer possible to distinguish the five different colors, turning into a gray patch, and the speed of absorbing the aura was also accelerated. There was a burning sensation in his dantian, as if a fire was burning.

But Sun Yi couldn't care about this extremely uncomfortable scorching heat, and ran the Five Elements Guiyuan Gong with all his might, continuing to speed up the rotation speed of the spiritual power in the dantian, and frantically absorbing and refining the spiritual power.

A quarter of an hour later, the spiritual power that rotated in the dantian was no longer a disc, but turned into a gray ball, frantically absorbing the spiritual energy that escaped from the Peiling Pill and the external formation.

Tick!

A drop of cyan liquid dripped from the bottom of the ball into the dantian.

At the same time as this drop of spiritual liquid fell, the ball that had lost its balance instantly expanded, and it was about to burst!

The most critical moment has arrived!

I saw that just as the ball transformed by the aura was about to burst and burst, the black and white silk threads floating on it suddenly fell outside the ball, and then slowly tightened, and then suppressed it to the size of just now!

Tick! The second drop of golden spiritual liquid fell at the bottom of the dantian.

The wildly spinning ball riots again. But this time, there was a black and white silk thread "hoop", and it was only expanded a few times before it was retracted again.

Tick! Tick!

The ichor was dropping dripping.

Sun Yi'an's eyes were closed, his body was stamped with one hand, his body trembled slightly, and beads of sweat on his forehead kept sliding down his cheeks.

A day later

The aura that swirled outside Sun Yi'an's body followed every pore of him, scrambling to drill into his body first.

Three days later.

Sun Yi'an's body stopped shaking, but his breathing became rapid. The spirit stones on the ground had all fallen back to the ground, turning into ordinary stones that were dusty.

Five days later.

The spiritual power that swirled around Sun Yi'an's body had turned into a thin layer, and he frowned, as if he was suffering a great deal of pain.

Half a month later.

When the full moon was in the sky, Sun Yi'an sat motionless. Lang Xiao didn't take advantage of the moonlight to cultivate, and stood quietly not far from him, his eyes flickering, staring at him tightly.

Early morning of the twentieth day.

At this time, Sun Yi'an looked serene, breathing evenly, as if he was asleep.

But there's no way he's going to fall asleep!

At this time, in his dantian, the spinning ball was only the size of a thumb. And underneath the ball, a faint layer of five different colors of liquid is evenly distributed.

The two black and white slender silk threads transformed by the two qi of yin and yang have expanded into a ring that connects from end to end, encompassing the entire dantian, slowly rotating around the dantian, suppressing the spiritual power that may riot at any time.

The breakthrough has entered its final stage!

One day after January.

There was a loud and clear laugh from the small courtyard in the Medicine Immortal Valley.

"Hahaha! Hahahaha~"

"Finally...... Burst - broken - ! ”

Sun Yi'an's eyes stared at his palm.

At this moment, his divine light is restrained, and his eyes are clear and deep. Although the body is thin, it has its own majesty.

This power belongs to the monks of the foundation building period!

"That's right, the fixing period!"

Sun Yi'an suddenly let out a low sigh and quickly sat down. I was carried away by the joy of the breakthrough just now, and I almost forgot about it!

The so-called fixation period refers to the fact that within a few quarters of an hour after entering the foundation building period, the monk can choose whether to keep his face forever or let it grow old with the passage of time. Not only does it have the ability to break through the foundation building period, but it also has one such opportunity to break through the Dan period and the Yuan infant stage in the future.

For the most part, the monk's appearance has nothing to do with his age. It is possible that an old man who is over the age of old is just a Qi refining stage cultivator. It is also possible that a child who looks like a weak crown is an old monster who has lived for nearly a thousand years!

All this, except for the cultivation of some special exercises, is only related to the fixing period!

Generally speaking, most monks choose to grow old as the years go by. After all, it is also quite embarrassing for an old man who is about to live with a baby face.

However, there are also some monks with amazing talents, who are conceited that their cultivation speed is increasing day by day, and they will keep their appearance as when they broke through the foundation building period.

Sun Yi'an naturally chose the latter, it's not that he is confident in his cultivation speed, on the contrary, with his system, if there is no chance to splash the sky, his cultivation speed will only be slower than ordinary people!

The reason why he chose to fix his face at this moment is because he has an obsession in his heart.

Although he didn't seem to care much about the loss of his left arm now, he was actually thinking about it all the time.

The parents who suffer from people's skin and the slightest injury are unfilial!

He didn't want to see his parents under the Nine Springs with his crippled body after he fell one day.

And if you want to regenerate your broken arm, you can only cultivate to the Yuan Infant Stage!

Although it seems to him to be a luxury, as long as he is alive, he will move towards this goal!

After another cup of tea, Sun Yi'an stood up, refreshed.

Of course, happy things should be shared with those closest to him, he turned his head, flew to Lang Xiao on the side, and gave him a big hug!

In Sun Yi's heart, Lang Xiao is not a spirit beast or a demon beast, he is the dearest brother!

After Lang Xiao swallowed the two demon pills of the First Tribulation Demon Beast Green Snake, he had already faintly reached the level of the middle of the first order, and there were a lot more silver spots in his eyes. But if you want to advance to a second-level demon beast, it is impossible without dozens of second-level demon pills.

Demon beasts are more advanced than human monks!

Thinking of this, Sun Yi'an couldn't help but feel a little regretful that he didn't find a single demon pill in the storage bags of the more than ten demon cultivators he had killed.

But he was relieved to think about it, he himself was a cultivator in the Qi refining period, and he hadn't even seen a few demon beasts, let alone killing demons and taking pills.

After the frolic, Sun Yi'an changed out of his sweaty clothes that were a little stiff after drying, stepped on the flying sword and flew towards the main peak of Beixiong Peak.

Now that he has advanced to the foundation building period, he naturally wants to report to his master Geng Pojun.

Of course, the main purpose in his heart was the spirit stone!

In order to break through this time, the spirit stones on his body were exhausted, and if there were no spirit stones, it would be impossible to arrange the formation in the future.

The monks of the foundation building period are the backbone of the sect, and they can no longer be regarded as disciples in the Qi refining period, and they generally hold corresponding positions, and their monthly monthly income is also dozens of times that of the disciples in the Qi refining period.
