Walking up the canyon for another hundred meters, Ling Chen felt that the density of the energy particles had thinned somewhat.

Upon careful perceiving, the energy particles were indeed floating from behind them.

The center of Reiki should be behind you.

Fifty meters back, where the density of energy particles was highest, Ling Chen slowly climbed down along the stone wall.

The lights of the scenic spot could not shine on this side of the canyon, and the depths of the canyon were dark, and he didn't know how deep the canyon was, so he didn't dare to jump down rashly.

He was only in the middle of his life, and if the canyon was more than fifty meters deep, he would burp when he jumped.

Three minutes later, Ling Chen reached the bottom of the valley, fortunately he didn't jump down recklessly, the depth of this canyon was more than one hundred and fifty meters!

There was no light at all, and Ling Chen could only sense the direction of movement of the energy particles with his powerful qi sense and spiritual power.

Soon, Ling Chen sensed that the energy particles did not emerge from the bottom of the canyon, six or seven meters away from him, there should be a very small canyon, and the energy particles he sensed were all emanating from that small canyon.

Ling Chen walked over in the dark, took out his mobile phone, turned on the flashlight and shook it.

The light of the mobile phone flashlight, at the bottom of this valley more than 100 meters deep, the visibility was outrageously low, but Ling Chen still saw the small canyon he expected in general.

In fact, it is not a canyon, in fact, it is a cave more than one meter wide and four or five meters high.

Ling Chen was happy, and he prepared such a cave suitable for cultivation for his brother?

Entering the cave, Ling Chen immediately began to condense the aura of heaven and earth.

It couldn't be easier to condense the aura of heaven and earth in this cave, although he didn't know how deep the cave was, but the width and height were there, the space was so big, and the energy particles were almost around him.

Even if you can't condense aura, as long as you can sense the existence of energy particles, you can absorb some energy particles to some extent.

The density of the aura in this small cave is no worse than that of the Ancient Martial Realm, not as dense as the Bay Creek in Sanssouci Valley, but denser than anywhere in the Huayi Gate!

Ling Chen was even wondering if the full moon still couldn't condense the aura of heaven and earth, would he bring her here as well.

But Ling Chen immediately dispelled this thought.

If you can't take the initiative to condense the aura, no matter how rich the aura is, there are very few energy particles that can be absorbed, even if it is absorbed for ten days and a half months, the absorbed energy particles are not enough to gather into true qi.

If there is no true qi in the meridian dantian, it cannot be regarded as a martial artist.

Moreover, although the aura in the small cave was dense, it was by no means inexhaustible, even if Ling Chen couldn't exhaust the aura here by refining the tailbone this time, he still had his vertebrae and skull bones that had not been refined.

In the later stages of the transformation of energy, the consumption of aura will increase exponentially.

Ling Chen, who was running the mental method, was like a big sponge, and as soon as the energy particles approached him, they immediately poured into the pores of his skin.

As soon as he began to absorb the aura, the energy particles in the cave no longer escaped outward, and even the energy particles in the canyon outside flowed back.

Twenty minutes later, Ling Chen stopped absorbing aura.

The spiritual power was not consumed much, the key was that his meridian dantian could no longer hold more true qi.

Even the hardened ribs and sternum have reached saturation at this moment.

Originally, when he came down from Bachelor's Mountain, the true qi in his body was at the peak, and he fought with Meng Guanglin in the Tengfeng Building, and then showed his strength in the preliminaries of the martial arts competition, and there was no additional consumption of true qi.

His true qi was actually kept in a semi-saturated state, coupled with the dense aura in the cave at the bottom of the canyon, and his qi sense and spiritual power were extremely powerful, so he quickly restored the true qi in his body to its peak.

Ling Chen stopped absorbing the aura, and the energy particles in the cave began to escape again.

Ling Chen was overjoyed, it seemed that the amount of aura in the Weaving Cave was not a few, perhaps, it was enough to support him to refine his spine, and even his skull.

The spiritual power was not consumed much, the true qi returned to its peak state, and Ling Chen immediately began to refine the tailbone.

The coccyx is not numerous and is formed by the healing of four coccygeal vertebrae, but the area of the coccyx is large, and basically no one can quench the entire coccyx at once.

That is, it is almost impossible to perfectly quench the coccyx.

But Ling Chen was different, thanks to his strong spiritual power, his control of spiritual energy far surpassed that of other martial artists, coupled with his strong spiritual power, it was not difficult to temper the entire coccyx at the same time.

Because the aura is very subtle, Ling Chen's speed of refining the tailbone is relatively slow, but slow work produces meticulous work, he tempers it once like this, it is worth refining it a hundred times for others!

Besides, he was refining the entire tailbone at the same time, and even the progress of a single tempering was much faster than that of other martial artists.

Under the guidance of powerful spiritual power, a large amount of spiritual energy surged towards the coccyx, completely enveloping the coccyx.

Countless energy particles shuttled through the pores of the coccyx, and a large amount of impurities in the coccyx were quenched, and Ling Chen could almost hear the sizzle of the impurities falling off.

The impurities fall off, and the aura is immediately filled.

The energy particles continued to seep into the tailbone, and the true qi in Ling Chen's body was gradually decreasing.

When Ling Chen first tempered his ribs, it only took about an hour, but now he was refining his tailbone, firstly because of the large area of the tailbone, and secondly, because he split the aura into a more subtle one, the time for a single tempering had also become longer.

Two hours later, the true qi in Ling Chen's body was exhausted, and there was still a lot of spiritual power left.

Now his situation is that the upper limit of his spiritual power is comparable to that of Dan Jin masters, and even the spiritual strength of some weak Dan Jin masters is far inferior to him, but the true qi that his meridian dantian can hold does not have much advantage compared to martial artists of the same level and rank.

Of course, there are still some advantages, after all, his ribs and sternum are quasi-perfect tempering, and his ribs and sternum absorb more aura than others.

However, it is far from the point of skipping the level.

While he still had spiritual power, Ling Chen immediately condensed the aura of heaven and earth.

After two hours, the spiritual power was exhausted, but Ling Chen's dantian and yin, yang, and yin three major veins were full of true qi.

The true qi consumed has almost recovered halfway!

In the past, in the back mountain of Bachelor's Mountain, it took almost a day to recover half of the true qi.

And now it only takes two hours!

Of course, it has something to do with the further improvement of his spiritual power, but more importantly, the aura in the cave of the Zhijing Cave is far denser than the mountain behind the Bachelor's Mountain!

Ling Chen was overjoyed, originally he expected that it would take at least half a month to come to Zhijingshan to refine the tailbone, but with the current speed of true qi recovery, it would take about ten days to quench the tailbone!

At the branch base of the Martial Arts Association, Brother Chen said that he would break through the peak of the mid-stage of Huajin within twenty days, except for the full moon, I am afraid that everyone thought that Brother Chen was bragging.

Haha, now Brother Chen will break through in ten days, do you kneel or not?
