Under Chu Yun's calm and delicate control, the condensed spiritual power at the dantian was gradually compressed into a small vortex-like thing.

At this moment, the air around his body suddenly crackled as if it had exploded.

Such a movement shocked Mu Xiaoxiao's heart.

However, she soon discovered that the heaven and earth aura near this mountain cliff was clearly spontaneously surging towards Chu Yun's body.

It doesn't seem to be a bad thing.

"All the accumulation of the Qi Condensation Realm is for this time...... It turns out that building a foundation not only requires the spiritual power accumulated by itself, but also needs to attract the majestic spiritual energy of heaven and earth......" Mu Xiaoxiao whispered.

She could feel that near Chu Yun's dantian, it seemed to be emitting a strong attraction, causing the aura of heaven and earth to spontaneously converge.

After those heaven and earth spiritual qi entered Chu Yun's body, they circulated dozens of circles along the meridians, and after tempering, they turned into controllable spiritual power, all of which moved closer to the small whirlpool in the dantian.

As these new spiritual powers converged, the small vortex began to become unstable obviously.

The cyclone, which was originally rotating steadily, suddenly twisted a little, and even faintly collapsed.

Chu Yun's spirit never relaxed for a moment, and at this time, he finally swallowed the Zhuji Dan in his mouth along with the Seven Yin petals.

In an instant, the two fused into a medicinal liquid, condensed into one, and turned into pure medicinal power, spreading everywhere.

As Tsukidan went down, the restlessness of the cyclone subsided a lot.

There was also a fiery and violent impact in it, which was also calmed out by the Yin Qi of the Seven Yin Flowers.

Chu Yun's heart was horizontal, and he suddenly increased the rotation speed of the cyclone!

Around him, there were also silent fluctuations.

As the vortex of spiritual power rotated rapidly, more and more huge foreign aura turned into its own power and continued to merge into the vortex.

The vortex grew much larger in an instant, but it was quickly suppressed again.

If the whirlpool is allowed to grow, the final result will inevitably be an explosion and death.

And one of the key steps in building the foundation is to strangle this cyclone into a small thing, turn the qi into a dan, and integrate it into the dantian!

Of course, this kind of "pill" is not a golden pill that immortal cultivators will cultivate in the future, but only a manifestation of compressing spiritual power to the extreme.

After that, this Dan-like thing will be developed into a sea of qi.

As the cyclone in Chu Yun's body was compressed to the point where it could no longer be compressed, his body was already sweating profusely.

The clothes on the upper body were also shattered due to the impact and destruction of the aura.

Just as the last stream of heaven and earth aura was refined and absorbed by him, the "Spirit Power Pill" that had just been condensed was finally overwhelmed and collapsed in Chu Yun's body!

This step is like opening up a new world in the chaotic universe, and it is also crucial.

The result of the collapse of the Spiritual Power Pill is either to turn into nothingness and severely damage the person who builds the foundation, so it naturally represents the failure of the foundation building;

Either that, at the same time as the collapse, a separate small space or even a small world is opened up -- this is the so-called sea of qi! The emergence of the sea of qi means that the foundation has been successfully built ninety percent. As long as there are no accidents, everything will be fine.

Just when the "Spirit Power Pill" in Chu Yun's body collapsed.

He clearly felt that a new space was rapidly forming inside the dantian......

The sea of qi is about to be completed!

Chu Yun could feel the process of the formation of the Qi Sea, and he could be sure that the Qi Sea this time was definitely more perfect than in the previous life.

However, he didn't rejoice too soon.

If the development of the Qi Sea is the most critical step in building the foundation, then after this step, there is a final step.

It's just that the last step is often not dangerous, but it is like a fixed process, and during the period when the sea of qi is formed, every person who builds the foundation will go through this process.

At the same time that Chu Yun quietly sensed the formation of the sea of qi, his consciousness involuntarily began to blur.

The next moment, he felt that he had lost all perception of the outside world, and a scene of visualization appeared in his consciousness.

However, what he "saw" was a chaotic void space, in which there was nothing, like a completely empty night sky.

"What's going on? Visualize...... Failed?" Chu Yun looked at his feet, and couldn't help but be surprised and suspicious.

Originally, everything was in his plan, but this stubble completely exceeded expectations.

Generally speaking, in the final stage of the Tsukidan, any kind of thing will appear in the consciousness of the Tsukidan.

This phenomenon is called "visualization".

The things that each person visualizes before the end of the foundation building are also different, but most of them are ordinary things that are common in heaven and earth. It may be flowers, birds, fish and insects, or it can be a grass or tree, or even a mountain, the sea, and various animals......

But now, Chu Yun found that what he was visualizing was only the boundless emptiness.

"Strange ......"

A normal visualization is one in which something appears in the consciousness.

However, Chu Yun's current situation is that the consciousness itself has come to another void space. This kind of thing was something he had never heard of before.

In his previous life, Chu Yun visualized a goshawk.

At that time, his master also praised this. This is because the more complex and higher the things that the person who contemplates the foundation builder is, the higher the person's achievements in the immortal path.

Ordinary people only visualize things like weeds, but Chu Yun visualizes goshawks at that time, and the gap between the two is self-evident. After that, Chu Yun reached the realm of Jindan at a young age, which can be regarded as confirming this.

Moreover, Chu Yun's personality is also the kind of person who does not follow the world and is a little evil, which is somewhat similar to that of the eagle.

At this time, this piece of nothingness in Chu Yun's consciousness suddenly began to distort!

Then, a huge sound sounded, as if it was real, and it sounded in Chu Yun's heart!

In other words, Chu Yun at this moment can no longer distinguish between fiction and reality. In his perception, everything in front of him is real.

At the same time as the roar and tremor erupted, cracks suddenly cracked in the void space.

Click, smack!

It was as if an earthquake had come, and the entire void space began to shake. However, the earthquake was just a shaking of the ground, but this seemingly endless dark world was actually shaking in its entirety.

Such a scene of apocalyptic catastrophe made Chu Yun's heart be shrouded in fear for no reason.

This fear was so clear and real, and even Chu Yun's true body had changed dramatically.

His body, for some time, was covered with sweat, and his skin was covered with a burning breath.

Not only that, with the mountain cliff as the center, the surrounding spiritual energy was furious to the extreme, surging wildly around Chu Yun.

Mu Xiaoxiao was in this aura storm, and he couldn't help frowning slightly. Although she didn't understand the key to building the foundation, Chu Yun's physical state had clearly calmed down just now, but now she suddenly had such a violent restlessness, so she couldn't help but worry......

While Chu Yun was in fear in the void world, the five Qi Condensation Masters in the Shen Mansion, led by Qin Hu, had already begun to implement the plan - the night of the full moon was when Chu Yun died!
