Fortunately, Du Yushang has no feet, otherwise with her mood at the moment, she would be able to step on the ground of the practice room out of two rows of pits!

"I don't know what to do, stinky boy, I want to see how you build a foundation without pills!" Du Yushang secretly thought to himself, but after all, he didn't transmit the sound in the sea of knowledge and disturb Lu Bowen's cultivation.

Soon there was silence in the practice room, and at this time, Du Yushang suddenly felt that a spiritual power was slowly injecting into her stone body from the passage constructed by the contract, although this spiritual power was not strong, but it was endless, like a flowing spring rain, washing her body and bringing her wisps of vitality, and after this spiritual power swam around her stone body, half of it would stop in her body, and the other half would be refined and returned to Lu Bowen's body along the channel.

！！！？？

Wait a minute!

Let me figure it out!

Isn't this special meow the legendary double cultivation?

The only difference from double cultivation is that she can't cultivate at the moment, so the process of this double cultivation is only halfway through.

Don't think that double cultivation is something that cannot be described, in fact, in a broad sense, double cultivation refers to the process of men and women cultivating at the same time, complementing each other's yin and yang, and refining spiritual power to nurture each other. Only double cultivation in the narrow sense is something that cannot be described.

However, whether it is double cultivation in the narrow sense or double cultivation in the broad sense, it is a relatively private matter, and most of them only happen between Taoist couples, and Du Yushang has never double-cultivated with others in his hundreds of years of cultivation career.

"So, my first double cultivation, why did I go with such a disgusting guy!?"

However, no matter how angry she jumped and resisted, the "double cultivation" was going on in an irreversible way.

A few days later, Du Yushang had changed from resistance to double cultivation to adaptation, and there was still a little joy that she had even thought that if she could maintain her current state for two or three years, she would probably lie down like this and enter the foundation building period.

What a winner in life!

The only regret is that she still can't cultivate right now.

Du Yushang has analyzed all kinds of possibilities in her current state, and the most reliable and closest to reality is that the egg she parasitized was left after the fall of Tianfeng, but because the environment was very bad at that time, or Tianfeng was too seriously injured, although the egg was still alive, the autonomous consciousness in it had already died, even if Tianfeng burned it with his Nirvana fire for tens of thousands of years, he could not save it.

An egg without independent consciousness naturally cannot collect the spiritual energy of heaven and earth to grow and develop, and it will look like a stone if it is burned by the fire of Nirvana all year round, and it is covered with too much molten earth.

If there is no accident, this egg may gradually die out in a few years, and it will become a stone completely, and no one will know that this stone once gave birth to a phoenix!

However, a wisp of Du Yusheng's broken divine sense entered this stone by chance, because she had refined the essence blood of the heavenly phoenix, and there was homology in the bloodline, so she had the opportunity to attach the remnant soul to the still alive phoenix egg, but she was not a real phoenix, so she could not collect the spiritual energy of heaven and earth for growth and development, let alone cultivate independently.

Fortunately, she signed a contract with Lu Bowen by mistake, otherwise she could only be trapped in the egg and could not be freed, and she was confused until her consciousness died.

Perhaps, this is the glimmer of life left by Tianyan Sijiu.

As for whether this speculation is correct, we will have to wait until one day the spiritual power accumulation reaches a certain level and hatches.

There is no sun and moon in cultivation, and more than thirty days have passed in the blink of an eye.

Lu Bowen's breakthrough also reached a critical moment, and the surging spiritual power hit the last acupuncture point on his body again and again, once he broke through this acupuncture point, it meant that he had stepped into the foundation building period, and since then he has broken away from the ranks of mortals and become a real monk.

However, building a foundation is not that simple.

Looking at the entire cultivation realm, there is no one in ten thousand who does not need to build a foundation pill by their own strength, most monks need at least one foundation building pill to successfully build a foundation, and monks with poor qualifications even need several foundation building pills, of course, there are many unlucky ghosts who fail to build a foundation even if they take a foundation building pill.

If the foundation building fails, the last acupuncture points cannot be broken away, and the spiritual power will not be able to form a great Zhou Tian in the meridians, and the huge spiritual power condensed for the breakthrough will inevitably get out of control and regurgitate, turning around and impacting those meridians and acupuncture points that have been opened, the meridians will be damaged, and the foundation will be destroyed.

Lu Bowen's situation at this time was a precursor to the loss of control of his spiritual power.

Although he had accumulated enough spiritual power before the deduction, he always felt that it was still a little bit short, just a little bit short, if there was a Tsukidan at this time, then he would definitely be able to break through smoothly, but he didn't. And the spiritual power in his meridians has been used to break through, and he can no longer run the exercises to introduce new spiritual power, and the little bit he lacks will never be able to make up for it without relying on external forces.

If nothing else, this situation will continue until his divine sense is unable to restrain the spiritual power in his body.

Of course, once the spiritual power gets out of control, the result is a failure to build the foundation.

Lu Bowen also knew that the situation was not good, but he didn't want to give up, and he still barely restrained the spiritual power in his body so that they would not get out of control for the time being, but his divine sense was already tired, and he was afraid that it would not last long.

Du Yushang sighed and said secretly: If this kid is abolished, I may not be able to meet a soft-hearted and talkative fool like him if I sign another contract, just return it to its original owner, you can save it again if your spiritual power is gone, and it will be difficult to mix fools without liars.

Forced to retreat for dozens of days, Du Yushang has mastered the method of mobilizing her own spiritual power, although she has no exercises to practice, but when she is bored, she always drives the spiritual power in her body to turn around, and now it is naturally easy to send this spiritual power back into Lu Bowen's body from the contract channel.

She originally thought that it was just a matter of transferring a little spiritual power, and if the situation allowed, she could still keep some family money, but the actual situation was beyond her expectations.

The contract channel between the two had just opened, and a suction force suddenly arose, sucking away all the spiritual power she had managed to accumulate, not counting, the suction force actually began to pump the vitality in her body, although it was only for a moment, but for Du Yusheng, who had not yet recovered and was still very weak at this time, it was undoubtedly a catastrophe, she only felt a sharp pain in her consciousness, and suddenly lost consciousness.

Fortunately, she lost consciousness, and the contract channel lost her consciousness and was automatically closed, so although she lost part of her vitality, she was not sucked into an egg, at least her life was saved.

Lu Bowen's divine consciousness was about to collapse, and his successor was already weak, but at this moment, a stream of spiritual power suddenly poured into his body from the contract channel, and this spiritual power, which was more pure than his own spiritual power, poured in, and suddenly strengthened the power of the buckle, and his exhausted divine consciousness suddenly inhaled a scorching breath, sweeping away the exhaustion.

He didn't care about getting to the bottom of it, but took this opportunity to break through his last acupuncture point in one fell swoop.

The acupuncture points were broken, the surging spiritual power calmed down, and a new line of practice was constructed in his body, he was busy running the foundation building period of the law, guiding the scattered spiritual power to run according to the established vein, and after a big week, he stopped cultivating, and he didn't care about stabilizing his cultivation, nor caring about being dirty, he got up and ran to the stones, and shouted: "Senior!"
