Xiao Chen opened his eyes, it was difficult to hide a bit of depression in his eyes, just now when he was about to become a pill, his divine sense control was slightly deviated, which led to the failure of the refining of the entire furnace of pills.

Closing his eyes and resting for a while, and waiting for his mind to stabilize again, Xiao Chen quickly cleaned up the medicinal residue and began refining it for the second time.

This time Xiao Chen was cautious, and there were no mistakes from beginning to end, and half an hour later, a strong medicinal fragrance came out of the Dan furnace.

Xiao Chen's face showed a little joy, and he opened the Dan furnace, where more than a dozen Zhuji Dan were lying in it.

Picking up one of them and examining it carefully, it was exactly the same as the one in his hand, Xiao Chen nodded with satisfaction, and put the rest into the jade bottle and put it away.

After gaining experience, Xiao Chen's speed of refining Zhuji Dan was greatly improved, and when night fell, he would refine all thirty materials. During this period, except for one accident that led to failure, all 28 materials succeeded in obtaining exactly 400 Tsukidan.

Looking at the Tsukidan full of four large bottles, Xiao Chen's face was full of pride, presumably even those core disciples of the great sects had never seen so many Tsukidans at one time in their lives.

Looking at the four hundred Tsukidans, Xiao Chen hesitated a little and put three of them into the storage bag.

"Three hundred pieces are enough for me to use to build a foundation, and the remaining hundred pieces might as well try to purify it, if you can get a medium-grade or high-grade foundation building pill, the cultivation effect will definitely be better." ”

Five hours later, looking at the nineteen Zhuji Dan in front of him, which had far improved in terms of luster and medicinal fragrance, Xiao Chen's face also showed a bit of pain. At the beginning of purification, although he had reached the tenth level of the Qi refining stage and his divine sense had been greatly enhanced, the difficulty of refining Zhuji Dan was still a little beyond his imagination, and after failing more than a dozen times in a row, he began to slowly succeed. But after a hundred tests, only nineteen medium-grade Zhuji Dans were obtained, and the success rate was barely two percent. Sighing, Xiao Chen carefully guarded the nineteen medium-grade Zhuji pills, swallowed a few pills, and closed his eyes to meditate.

First refining the Zhuji Dan, and then purifying it, Xiao Chen's divine consciousness and spiritual power have already consumed seventy-seven eighty-eight, even if there is a large amount of pills to swallow, it will be three hours later when he fully recovers.

took out a Tsukidan and Xiao Chen swallowed it. In an instant, the cool and docile spiritual power in the body rioted, running wildly along the meridians over and over again. As the medicinal power continued to be absorbed, the volume of the spiritual power also increased rapidly, becoming more refined. Xiao Chen guarded the spiritual platform tightly, not intervening in the slightest about the changes in the spiritual power in his body, and let it go crazy and spin.

Half an hour later, the almost boiling spiritual power in his body gradually subsided, and Xiao Chen opened his eyes, with a bit of self-deprecation on his face. Medium or above talent, after reaching the eighth layer of the Qi refining period, he can build a foundation by taking the Zhuji Dan, but he is at the tenth level of the Qi refining period, and he can't build a foundation after taking the Zhuji Dan, which shows how poor the talent is.

But fortunately, Xiao Chen was prepared for this, so he calmed down quickly after laughing at himself. After a careful examination, although the foundation building failed, the spiritual power in the body was greatly increased, and it seems that this is the effect of the foundation building. Xiao Chen's heart was a little fixed, and he took out one again with his backhand and swallowed it.

With the first experience, this time the medicinal power refining was a little faster, Xiao Chen opened his eyes, swallowed a Zhuji Dan with an expressionless face, and then refined the medicinal power.

The third time he devoured the Tsukidan, as the medicinal power was absorbed, the boiling spiritual power seemed to have undergone some changes, Xiao Chen was slightly happy in his heart, could it be successful? When the medicinal power was absorbed, Xiao Chen slowly opened his eyes and carefully experienced the changes in the spiritual power.

At this moment, the volume of physical strength and spiritual power has increased again, and it has become more refined than before, and its divine sense has also increased a few points. Xiao Chen opened his eyes, and couldn't help but show a little wry smile on his face, although he made another breakthrough, but he definitely didn't succeed in building a foundation, so what kind of realm is it now, the eleventh layer of the Qi refining period? It seems that he has never heard of this realm at all.

Xiao Chen's face showed a bit of a deep groan, although devouring the Zhuji Dan did not succeed in building the foundation, his cultivation was constantly increasing, if he continued like this, when he reached the limit, he would naturally advance to the next cultivation level. Xiao Chen packed up his mentality, put a Zhuji Pill in his mouth again, and at the same time thought viciously in his heart: "Master is a lot of pills, if one doesn't work, there will be ten, and if ten can't work, there will be a hundred, if you don't believe in building a foundation, you can't build a foundation!"

For two months, Xiao Chen could not go into retreat. Swallowing pills, meditating, refining medicinal powers, and repeating them day after day.

After swallowing to the twenty-fifth pill, Xiao Chen had the feeling of breaking through for the second time, but he still had not built a foundation, and temporarily set the current realm as the twelfth layer of the Qi Refining Period.

Swallowed to the sixty-fourth, the third breakthrough, the foundation building failed, the thirteenth layer of the Qi refining period... The one hundred and fifty-seventh, the fourth breakthrough, the failure of foundation building, the fourteenth layer of the Qi refining period... The fifth breakthrough, the foundation building failed, and the fifteenth layer of the gas refining period...

Xiao Chen opened his eyes, his eyes were full of unwillingness, after refining this medium-grade Zhuji Dan, he only made the spiritual power in his body a little purified, and the number did not even increase by the halfest.

"Alas, it seems that this is already the limit that can be reached during the Qi refining period, but why can't I build a foundation?" This is already his tenth attempt, after refining nine lower-grade Zhuji Pills in a row without any changes in spiritual power, Xiao Chen really gave up and devoured a medium-grade Zhuji Dan, but the effect was still extremely limited.

After thinking for a while, Xiao Chen's face showed a bit of bitterness, the fifteenth layer of the Qi Refining Period, even to this point, he still couldn't break through, could it be that he got this anti-heaven alchemy technique, but his cultivation was going to stop at the Qi Refining Period?

Xiao Chen was full of unwillingness, and used the Qi Gathering Technique attached to "Mixed Yuan Nerve" to stabilize his cultivation at about the seventh layer of the Qi Refining Period, and then swallowed a Transformation Pill out of the valley.

Transfiguration Pill is a kind of partial pill, which costs a lot of materials, changes the user's appearance, lasts for three hours, and can only be taken again every other hour. However, it is not without flaws, and it is more than a big realm above the user, that is, it can see through the change of appearance. However, Xiao Chen is at the fifteenth level of the Qi refining period at the moment, and his spiritual power and divine sense are not weaker than ordinary foundation building cultivators, so he is naturally not afraid of being seen through.

The only real person in charge with this strength also retreated and protected the Dharma together when Yao Daozi hit the Jindan realm, Xiao Chen was naturally extremely relieved.

Out of the medicine garden, Xiao Chen soared into the air, although he did not use a spiritual weapon, but the speed was also extremely fast. In just half an hour, it was to the Falling Cloud Valley Classic Book Pavilion. Xiao Chen fell far to the ground, and the Classic Book Pavilion had a powerful ban on the air, and he would definitely not be able to fly until he reached the foundation building realm. Although Xiao Chen has this strength, he doesn't want to attract attention at the moment, so naturally he won't do such a stupid thing.
