After a few hours, Wang Xiaofan looked at the dozen or so medium-grade Zhuji Dan in front of him, and smiled wryly. One hundred low-grade Zhuji Dan was only exchanged for more than a dozen medium-grade Zhuji Dan, and Wang Xiaofan also felt a pain in his heart. Although Wang Xiaofan was already at the tenth level of the Qi refining period, the difficulty of refining the Zhuji Dan was beyond his imagination. After dozens of failures, Wang Xiaofan slowly mastered the rules, and finally began to succeed, but after testing a hundred Zhuji Dan, he only got more than a dozen in the end.

After Wang Xiaofan sighed, he put away the dozen or so medium-grade Zhuji Dan. Then he swallowed the elixir and sat down to regain his consciousness and spiritual power.

After an hour of recovery, Wang Xiaofan finally returned to his best state.

Next, it is time to start building the foundation, at this moment Wang Xiaofan has been waiting for a long time, and he can't help but feel a little excited in his heart.

Wang Xiaofan first tried to calm down his excitement, and then began to prepare to build the foundation.

Sit down cross-legged, then take out a Tsukidan and swallow it in one gulp. Then he began to move according to the exercises of the "Observation of the Sky and the Drawing of Qi Technique". Tsukidan's medicinal power began to dissolve, and the peaceful spiritual power in his body became as agitated as an angry dragon, running wildly along the meridians over and over again. As the medicinal power is continuously absorbed, the spiritual power in the body also continues to grow. Wang Xiaofan kept his mind tightly, let it impact like a thousand huge waves, he stood still, did not intervene, and let it run wildly.

After an hour, the boiling spiritual power in the body gradually became calm, and finally calmed down. At this time, Wang Xiaofan slowly opened his eyes, and a hint of darkness flashed in his eyes. In the eighth layer of the Qi refining period plus intermediate or above qualifications, most of them swallowed the foundation building pill, and they could build the foundation smoothly. And he is now at the tenth level of the Qi refining stage, but after taking the Zhuji Dan, he still has not succeeded in building the foundation, which shows how poor his qualifications are.

But Wang Xiaofan was already mentally prepared for this, so after a little depression, his mood calmed down. Carefully check the situation in the body, although the foundation was not successful, but the spiritual power in the body has increased a lot, it seems that this is the effect of the foundation building. Seeing that there was growth, Wang Xiaofan was a little settled in his heart, and then decided to continue to impact the foundation building period, and took out another foundation building pill with his backhand and took it.

With the first experience, this time the refining of medicinal power became faster, but after the refining was over, Wang Xiaofan opened his eyes expressionlessly, and then continued to swallow Tsukidan.

This time, after the medicinal power was completely absorbed, Wang Xiaofan clearly felt that the spiritual power in his body had changed. He was overjoyed and thought he had succeeded. He opened his eyes and carefully felt the changes in the spiritual power in his body.

The spiritual power has increased a lot compared to before, and it has become more refined, and his divine sense has also increased a little, but Wang Xiaofan still has a wry smile on his face. Although his spiritual power has made a breakthrough, it is definitely not the realm of the foundation building period. But what kind of realm is this, is it the eleventh layer of the Qi refining period? I haven't heard of this at all.

Wang Xiaofan had a thoughtful look on his face, although he did not succeed in building the foundation, but the growth of spiritual power and divine consciousness was indeed certain. If this continues, then it will be extremely difficult, and then the foundation building should be a matter of course.

Wang Xiaofan packed up his mentality, swallowed a Zhuji Dan again, and said fiercely in his heart: "I just use the Zhuji Dan pile, and I also want to pile it into the foundation building period, Lao Tzu doesn't have much else, and the more is the Zhuji Dan." ”

For two months in a row, Wang Xiaofan could not go out of retreat, and spent such boring days. Swallow the pill, meditate, refine the medicinal power, then swallow the pill, meditate again, and refine the medicinal power.

There is no fluke in success, only continuous persistence and continuous efforts.

After swallowing dozens of foundation building pills, Wang Xiaofan still did not build a foundation, but the realm broke through one layer, so it was tentatively set as the twelfth layer of the qi refining period.

After swallowing a hundred Zhuji Dan, there was still no foundation, but there was a breakthrough in the realm.

Okay, then go ahead and swallow Tsukidan.

There is still no foundation, and it is still only a breakthrough in the realm.

Again, it's the same.

Could it be that it is now the fifteenth layer of the Qi Refining Period, okay, then the fifteenth layer of the Qi Refining Period.

In the end, Wang Xiaofan directly took out the medium-grade Zhuji Dan, but this medium-grade Zhuji Dan only made the spiritual power a little purer, and did not even increase.

"It seems that this is the greatest extreme difficulty that can be achieved during the Qi refining period, but why can't I still build a foundation?" After swallowing ten medium-grade foundation building pills in a row, Wang Xiaofan found that his spiritual power could no longer grow.

Frowning and thinking hard, after a long time, Wang Xiaofan smiled bitterly, he was already at the fifteenth level of the Qi Refining Period, and he had reached this point, and he still couldn't succeed in building the foundation, could he let him get such an anti-heaven alchemy, but his cultivation would stop at the Qi Refining Period?

Wang Xiaofan thought hard again, and finally thought that Qingyun Sect had a Jade Book Pavilion, maybe go there to find the answer and see how people without spiritual roots built a foundation.

Wang Xiaofan performed the "Breathing Technique", stabilized his cultivation at the seventh layer of the Qi Refining Period, and then took out a face-changing pill and swallowed it.

The Changing Pill is a face-changing elixir that lasts for three hours. But it also has its drawbacks, a big realm higher than the user, you can see the change in appearance. But now that Wang Xiaofan's cultivation is at the fifteenth layer of the Qi refining period, the entire Qingyun Sect can see it, but I am afraid that only the head of the Qingyun Sect is the master. But the head of the Qingyun Sect is also in retreat at the moment, so Wang Xiaofan is fearless.

Out of his own medicine garden, Wang Xiaofan flew straight to Yushu Pavilion.

When he arrived near the Jade Pavilion, Wang Xiaofan fell into the light, because there was a strong prohibition around the Jade Pavilion, and it was forbidden to fly at high altitude. And at this moment, Wang Xiaofan also deliberately did not let people notice it.

The two true disciples of the Qingyun Sect outside the door of the Jade Book Pavilion saw Wang Xiaofan walking on his back, so they swept their senses towards Wang Xiaofan, and the two of them suddenly had a respectful look on their faces, and they saluted together: "Meet Senior Brother." ”

Wang Xiaofan nodded expressionlessly, and said lightly: "I want to enter the Jade Book Pavilion." ”

"On the first layer, you need a lower grade spirit stone to enter each hour. On the second layer, two lower-grade spirit stones are required to enter each hour. On the third floor, if you want to enter, you need the master's hand. There is also one thing that needs to be reminded that no items in the Jade Pavilion can be taken out. One of the disciples replied respectfully.

Hearing this, Wang Xiaofan nodded slightly, pondered for a while, then took out two lower-grade spirit stones from the storage bag, handed them to one of them, and said, "I will stay on the first floor for two hours." ”

Because the Transformation Pill can only support three hours, Wang Xiaofan can only stay in the Jade Book Pavilion for two hours, which also makes Wang Xiaofan very helpless.

When the two true disciples of the Qingyun Sect heard this, they immediately had strange expressions, but they still respectfully handed over a jade slip to Wang Xiaofan.

"Senior brother can take this jade slip and stay in the Jade Book Pavilion for two hours. ”

Wang Xiaofan took the jade slip and went directly into the Jade Book Pavilion.
