Gu Feiyu and Bai Feiyan retreated from their cultivation at the same time, and slowly opened their eyes, both of them knew that the time had come.

took out the jade bottle sent by Su Shujie from his body, opened the cork and poured out the only pill inside, "Is this the best Zhuji Dan......

Gu Feiyu didn't swallow it directly, but looked at it carefully with curiosity, Zhuji Dan was milky white, the whole body was smooth and greasy, and there were several faint lines on the Dan body under a closer look, and the lines on the Dan body were difficult to distinguish under the milky white, and the distance between each veins was the same.

The number of veins is still difficult to count at a glance, Gu Feiyu doesn't know what these veins mean to the pill, and he hasn't done too much research, but the foundation building is the most important thing at the moment.

He glanced at Bai Feiyan, and at the same time took Tsukidan, the entrance of Tsukidan was cold, but under this coldness, it seemed that a warm lotion melted, and he swallowed it down his throat.

Gu Feiyu sat cross-legged, closed his eyes slightly, faintly felt a faint warm feeling coming from his abdomen in his body, and without hesitation, he began to run the true qi in his body to try to build a foundation.

Foundation building is different from previous breakthroughs, and the usual breakthroughs are nothing more than breakthroughs to a higher realm, and the true qi in the body has become more condensed and thick.

The reason why Zhuji is called a watershed is because it is necessary to use true qi to build and open up a purple mansion in the body, and the formation of the purple mansion can be regarded as truly stepping into the cultivation realm, and the realm of refining qi is still a mortal fetus after all.

But the foundation building is different, once the foundation of the Purple Mansion is successfully opened up in the body, there will be at least one Jiazi's youth, that is to say, within sixty years, the body will remain the same as before the age of eighteen, both internally and externally, and there will be no signs of aging.

Not only has at least one Jiazi youth, but also has at least three Jiazi lifespan, if there is no accident in the future and is not killed, under normal circumstances, even if you don't cultivate after building the foundation, you can live to be more than one hundred and eighty years old, which is more than twice the lifespan of mortals.

Therefore, the Tsukidan in the Fang Market sells so expensive, after all, this is a life directly linked, an ordinary Tsukidan hundred spirit stones are worth a lot of money, but it can make people live for a hundred more years, in fact, it is already very cost-effective.

These are just for mortals or people with ordinary qualifications, qualifications like Gu Feiyu and Bai Feiyan, even if they don't have a foundation building pill, they can build a foundation in the end, but after having the best foundation building pill, the certainty of perfect foundation building will be much greater.

When Gu Feiyu controlled the true qi in his body and began to build purple, the best Zhuji Dan also began to exert its role worth two thousand spirit stones, and the lower abdomen began to slowly change from the initial warmth, and finally became extremely hot, and the qi and blood in the whole body seemed to be boiling, full of power.

Gu Feiyu felt that all the true qi in the muscles and veins in his body was full of great vitality at this moment, and he began to take the initiative to gather towards the construction of the Purple Mansion, and his control of the true qi was also more handy.

In Gu Feiyu's body, a milky white halo was forming, like a peeled hard-boiled egg, even the size was extremely similar, exuding a trace of Qi that swirled there at an unhurried speed.

Gradually, as time passed, the true qi in Gu Feiyu's body fell into conscious inertia and actively converged towards this milky white halo, Gu Feiyu simply gave up the guidance of the true qi and began to try to contact the milky white light cluster.

After the initial contact, perhaps this was the reason for the convergence of his true qi, the light group did not show the intention of resisting, but was a little affectionate eagerness.

Gu Feiyu was overjoyed in his heart, and began to make the milky white light cluster rotate faster, and while the light group gradually accelerated, the speed of the true qi in his body seemed to be accelerating, which made him even more surprised.

By now, Gu Feiyu was already a little handy in his heart, and he began to ignore the rest, just controlling the rotation of the light cluster, and just continuously converging the true qi in his body on top of the light cluster formed by the true qi.

I don't know how long this state lasted, once I fell into cultivation, the concept of time was a little vague, and I didn't know what had happened in the outside world, and how long it had been, it was not an exaggeration to describe it as a day in the mountains and a year in the world.

"Boom ......"

Gu Feiyu continued like this, until the last trace of true qi in his body gathered on the milky white light cluster, and the light cluster also reached the limit of rotation speed, and then he felt a bang in his body, and his whole body fell into a short period of stagnation and blankness.

This time was very short, Gu Feiyu didn't have time to be surprised before he recovered, but the light cluster in his body was no longer the same as before, but turned into a chaotic white, still the size of an egg, but it was full of vitality and vitality.

"Is this the Purple Mansion, I have successfully built the foundation!" Gu Feiyu thought to himself.

There was a trace of liquid in the milky white purple mansion that began to flow out, moistening the whole body along the meridians, Gu Feiyu felt that the whole body was indescribably comfortable, and the whole person seemed to be washed, as if it was moisturized.

From the outside, his skin has changed and become more hydrated. He sat opposite Bai Feiyan, and Bai Feiyan at this time also had the same change, perhaps because of the girl, her change was even greater, the whole person looked fairer, and her skin became more lubricated.

There is also a faint halo of light wrapping around the two of them, both of them are expressionless at the moment, carrying out the final transformation, I believe that they will be able to be reborn after today.

Gu Feiyu was surprised in his heart, the true qi in his body turned into liquid after the foundation was built, and it was changed by the Purple Mansion to become liquid, but now the true qi is too little, and even one-tenth of the tendons and veins can be said to be barren to the extreme, and it is very different from the one that was slowly supported before the foundation was built.

But what surprised him even more was that he didn't feel the weakening of his strength, but felt even more powerful at the moment, could it be because of the transformation into liquid?

After thinking about it, Gu Feiyu gradually understood, the true qi has been transformed from the previous gas to the liquid today, although the area occupied at the moment is only one-tenth of the previous one, but the strength has risen, the true qi of the liquid is undoubtedly more condensed, and the process of refining and condensing the true qi is now finally forming a liquid, and it is naturally out of the realm of refining qi.

After forming the Purple Mansion and the True Qi liquid, these two can be regarded as the real foundation building, this is the perfect foundation, if it is only the formation of the Purple Mansion and the true qi cannot be converted into liquid, I am afraid it is not a perfect foundation.

After reaching the realm of foundation building but still refining true qi and doing things in the realm of refining qi, how can he have great achievements in the future?

Perfect foundation building is not something to be proud of, this is just the most basic standard for stepping into the cultivation realm, although this is the case, but how many people can really build a perfect foundation? Even in the cultivation realm, I am afraid it will not exceed thirty percent.

Fortunately, Gu Feiyu did it! After realizing that he had successfully built a foundation, even the corners of his mouth hooked a shallow smile.

After successfully building the foundation perfectly, Gu Feiyu did not immediately withdraw from the state of cultivation with excitement, and now that the true qi in his body was lacking, he had to consolidate it first to make sure that there were no hidden dangers.

Finally, Gu Feiyu slowly opened his eyes, the light from the outside world was a little dazzling, and he was a little uncomfortable, presumably it should have been a few days.

Bai Feiyan's eyes were still slightly closed, and she was still cultivating, but seeing the changes in her body, Gu Feiyu was slightly startled in her heart, and hurriedly looked at herself, both of their bodies seemed to have been reborn, becoming white and smooth.

Looking at her changes, Gu Feiyu has no worries in her heart, and being able to have the same changes as herself means that she is also going to succeed.

While waiting for Bai Feiyan, Gu Feiyu was also feeling the changes in his body, it turned out that it was not only his body that had changed, but also some things that even he didn't know how to describe, and at this moment he seemed to be able to feel the things around him.

This feeling is very clear, even if you close your eyes, you can sense it clearly, and it is a little blurry in the distance, but some sounds can still be sensed, which makes Gu Feiyu surprised and happy in his heart.

Finally, it didn't take long for Bai Feiyan to slowly open his eyes, and then his eyes narrowed slightly, as if he was a little uncomfortable with the sudden light, and raised his hand to cover it.

Gu Feiyu walked to the edge of the bed and sat down beside her, looked at her appearance and smiled, and said, "How do you feel?"

Bai Feiyan saw that he was even earlier than himself, his eyes showed a slight surprise, and then said with a happy face: "You succeeded? It's so fast! Except for the fact that your eyes are a little dazzling when you just open them, everything else is very good, and you have built a perfect foundation!"

Gu Feiyu had already expected that she had succeeded, how could she not have a reason to succeed, he smiled and said: "That's good, we have all succeeded in building a foundation, in addition to these, there seem to be unexpected benefits in building a foundation, you close your eyes and sense the surroundings." ”

When Bai Feiyan heard his words, he smiled slightly, nodded, and said obediently: "Okay, I'll try it!"

Gu Feiyu watched her close her eyes again with a smile on her face, and then her face slowly changed, surprised, followed by surprise and puzzlement.

Bai Feiyan suddenly opened his eyes and said in disbelief: "I can sense you when I close my eyes, and I can sense everything outside the room, but it's too far away and blurry, what the hell is going on, it's amazing!"

Gu Feiyu smiled, he had just discovered it, so naturally he didn't know, and sure enough, everyone said that building a foundation was a cultivator, and compared to now, the previous half-step foundation building was not as good as even a finger.

The benefits after building the foundation are so great, far from the so-called Taoism and magic weapons.

Gu Feiyu was aware of this, and said: "I'm afraid the benefits of building a foundation will have to be studied later, I have sensed that someone is coming towards us." ”
