And after devouring the aura, this black qi will also assimilate the devoured aura and become a part of the black qi.

Cheng Su didn't waste any more time, but gathered his mind and practiced qi into his body, and only took a short rest when the aura in his body reached saturation again.

She planned to break through the Qi training period in the next one or two days to build a foundation.

The next day, at the same time, when the hour hand pointed to eleven o'clock, she entered the bamboo house space again.

She vaguely felt that she might break through the Qi training period tonight, and at this time, her mood became nervous for no reason, and she knew the consequences of failing to build a foundation.

The consequence of this is that it will be even more difficult to build a foundation again, and those who are unlucky will stay in the Qi refining period for the rest of their lives and achieve nothing.

It can be said that every time an immortal cultivator rises a step, he is fighting against fate, and if he wins, he will be directly promoted, and if he loses, he will only be a chicken feather.

In the space of the bamboo house, Cheng Su's mind sank into the dantian, and the aura in the dantian was rippling at this time.

Except for the black qi wrapped in aura in the corner, the entire dantian was already filled with aura at this moment.

Every trace of aura in it is the condensation of her Cheng Su's spirit.

However, the aura in the bamboo house was still flowing into her body from all the meridians in her body, gradually forming a small aura cyclone in her body.

Cheng Su poured all the Qi Cultivation Pills in the porcelain bottle into her mouth, and the aura in her body suddenly skyrocketed, such a surge almost made her uncontrollable, but the feeling around her body was wonderful.

It's a wonderful way to qualify.

She tried her best to refine these aura, refining and condensing it many times, and the aura in the meridians of the dantian and her body gradually transformed from the initial pale color like smoke to the pure jade white.

Then gradually formed the substance, she looked inward at the moment, and could no longer see the black qi in the corner of the dantian, which should be the reason why the aura was too condensed.

However, she could still vaguely feel the position of the black qi, and she didn't dare to be distracted, she continued to wrap the black qi with part of the aura, and the rest of the aura was used to refine the dantian.

Gradually, her face turned pale, and a large amount of spiritual energy continued to pour into the dantian and transform into spiritual power.

And the jade-white aura in the dantian that has condensed into an entity blooms violently like brilliant fireworks, constantly washing and expanding around the dantian.

But at this moment, the black qi suddenly became agitated while the aura was disordered.

Cheng Su immediately felt a tingling pain coming from inside the dantian, and then there were signs of instability in the dantian.

The sudden appearance made her face pale, and her body trembled slightly involuntarily, and she was only one last layer of tempering away from breaking through the foundation building.

If you don't succeed, you will become a benevolent!

She mobilized her mental power and tried to control the chaotic aura and suppress the black qi.

The black qi seemed to sense this unprecedented threat, and it trembled violently even more, and kept rushing left and right.

With a bang, the black qi mixed with the aura turned into a little starlight and exploded in Cheng Sudantian.

Cheng Su only felt a bang in her head, the starlight was shining, her divine sense expanded a lot, and the starlight gradually dissipated in every corner of her body.

When she opened her eyes again, a streamer flashed in her eyes, and it was done, and she succeeded in building the foundation.

The chaotic aura in the body also tended to calm down, and the dantian, which was originally able to fill the aura quickly, was greedily sucking this aura like a stream flowing into the sea when it absorbed the aura in this bamboo house at this moment.

She looked inward again, and now she could see the meridians around her clearly.

The meridians around the body are much stronger than those during the Qi refining period, and the spiritual energy in the tendons and veins is like a stream, continuously converging the spiritual energy into the dantian and transforming it into spiritual power.

And the shadow part in the dantian has also disappeared, and the black gas is gone?

No, she could feel the existence of this black gas, but she didn't see the shadow of the black gas when she searched everywhere around her now.

Could it be that this black qi was refined by himself when he broke through the foundation just now?

At this moment, she once again felt the subtle changes in her body, and she saw the shadow of the black qi from the rich spiritual power in the dantian.

The black qi had merged with the aura, and she didn't feel anything wrong with her body.

Got up and came to the window of the bamboo house, it was still white outside, and she condensed her spiritual power into essence and shot out from her fingertips.

She could clearly feel that the spiritual power that shot out was mixed with a trace of imperceptible black qi.

Now this condensed entity is shooting out spiritual power, and it is no longer an aura entity, and its power far exceeds that of the aura entity several times.

The comparison between the Qi training period and the foundation building period is not only a qualitative leap, but also a leap in strength.

At this time, she had successfully built her foundation, and the storage of this aura was much more than that of the Qi cultivation period.

As far as the matter of black qi is concerned, it is currently resolved, but she doesn't know what the consequences of the combination of black qi and aura will be, and she still can't know.

Fortunately, she has successfully built a foundation, which is also the most gratifying thing for her in recent times.

Looking up at the hourglass, Cheng Su felt strange that the hourglass was a little bigger than before.

I blinked, making sure I was not mistaken, it was indeed older than before.

Could it be that this is what the book says, that the cultivation of the owner of the bamboo house determines the level of the bamboo house?

Now that her cultivation has been promoted to the foundation building period, this hourglass has also been upgraded by one level?

Can this time be slower? Until the slowest,

Thinking so in her heart, the bamboo house seemed to resonate with her, and immediately let out a slight roar.

When Cheng Su looked at the quicksand in the hourglass again, it was indeed a lot slower.

Compared with the previous speed, it is at least twice as slow, and the original six hours outside is equivalent to twelve hours in the bamboo house, so now it means that twenty-four hours in the bamboo house is equivalent to six hours outside.

In short, the time outside remains the same, but the speed of time in this bamboo house is twice as fast.

Cheng Su smiled, this hourglass is really a treasure, it seems that as long as she breaks through the first level in the future, the flow rate in this bamboo house will be doubled.

Looking at the space in this bamboo hut, it was obviously much larger than before, and she wanted to separate a separate room for occasional rest.

As soon as I thought so, I heard the crackling sound of the bamboo house as if it had touched some kind of switch, and the space in the bamboo house really changed.

It's really a separate antique room.

It's just that the spiritual power in her dantian has also consumed a lot, and there are less than forty percent left.

She is now a foundation building stage monk, and she doesn't have to sit down and calm down to induce qi into her body like she did during the qi training period.

As long as she is in this bamboo house now, the meridians around her body will continuously inject spiritual energy into the dantian and transform it into spiritual power.

With a happy mood, she glanced at the water lily in the porcelain basin on the table, which had grown buds the size of fingernails and floated on the water.

And the little silver fish was swimming quietly in this pot, and when she saw the little fish, she remembered to feed, and it had been a day since the last feeding.

When he came to the bookshelf, he opened the small porcelain bottle containing the spirit feeding pill, poured one out of it and threw it into the water.

Just see this silver little fish, take a bite and swallow this spirit pill directly.

Cheng Su poured out all the spirit pills in the small porcelain bottle, counted them, and there were eleven in total, if it was one a day, it could be fed for eleven days.

And what about eleven days later?
