After checking the situation of the coccyx quenching, Ling Chen was still very satisfied.

Dense, tough, and even, the coccyx is like it will breathe on its own, swallowing the aura around the bone.

Of course, in terms of appearance, it is not like the translucent effect when the ribs are first tempered, but there is some jade texture at the very edge.

But Ling Chen had already been mentally prepared, the coccyx was a whole piece, and it was far thicker than the ribs, even if he had the true qi of a psychic master, and the spiritual power of a god master, it was impossible to quench the coccyx into a translucent state for the first time.

In fact, even those geniuses in the Ancient Martial Realm would take at least three months to quench the edge of the coccyx into jade!

And Ling Chen only used it for half a day!

Mental energy was exhausted, a wave of fatigue hit, Ling Chen took out his mobile phone and looked at the time, it was already past two o'clock in the afternoon, he ate some dry food and rested on the spot.

When I woke up, I couldn't hear the hustle and bustle of the tourists outside, and the lights in the scenic spot were turned off.

At this point in time, no tourists are still left in the Zhijing Cave, and Ling Chen is left alone at this moment in the Zhijing Cave of hundreds of thousands of square meters.

If it was in the past, Ling Chen was alone in such a dark place, and he was not afraid that it would be fake, but now he is a master of transforming strength, and he has been alone in the mountain behind Bachelor's Mountain for more than ten days, and he is used to loneliness, and he is not afraid at all.

The mental power was restored, and there was no rush to absorb the aura.

The cave he is in now should not be the center of the aura of the Weaving Cave, when he condensed and absorbed the aura before, the energy particles outside the cave flowed back, but more supplements came from the depths of the cave.

There is no doubt that the aura in the depths of the cave should be more dense.

With the faint light of his phone's flashlight, Ling Chen walked deeper into the cave.

Indeed, as he expected, the aura in the depths of the cave was denser than outside, and it was estimated that some energy particles had penetrated into the surface through the cracks in the rock formations.

The cave twists and turns, sometimes wide and sometimes narrow, walked more than a hundred meters inward, and Ling Chen stopped abruptly.

Ahead, there is a whole rock wall, and there is no way out.

Ling Chen frowned, a look of doubt in his eyes.

The caves are all ordinary rocks, and there is no possibility of generating energy particles, and there is no energy on the rock wall in front of them, so where does the aura in the Weaving Cave come from?

Ling Chen shook the flashlight of his mobile phone upwards, but the faint light made it impossible to see at all.

Turning off his phone, Ling Chen didn't continue to explore.

He came to Zhijing Cave to refine the tailbone, he had no interest in exploration, and now the aura here is rich enough, very close to the Bay Creek in Sanssouci Valley.

In addition, where the energy particles come from, as long as you condense and absorb the aura of heaven and earth, you can know.

The mental method was running, and Ling Chen's whole person suddenly seemed to have turned into a large magnet with super strong magnetic power, and the energy particles in the cave were instantly absorbed around him.

As the energy particles frantically poured into the pores of the skin, the energy particles in the cave outside also began to flow back, and above the rock wall, more energy particles also floated down.

The aura really came from above!

After ten or so minutes, there were very few energy particles flowing back in the cave outside, and Ling Chen also sensed that the energy particles in the cave came from above his head, about fifty meters in the air!

It is also impossible for the air to produce energy particles, and Ling Chen judged that there should be a cave about fifty meters above the entire rock wall in front of him, which should not be far from the center of the aura of the Weaving Cave.

Ling Chen was not in a hurry to go up, and he absorbed the aura in place with peace of mind.

Two hours later, Ling Chen's True Qi returned to its peak state.

took out his mobile phone and turned on the flashlight, shook it above his head, and Ling Chen slammed into the air!

He has no interest in exploring, but how can he be willing not to go to the aura center of Zhijing Cave.

With Ling Chen's current strength, he couldn't fly fifty meters in the air at a time of stepping into the air anyway, and besides, he didn't dare to jump up with all his strength, in case the top of his head hit a rock or something, it would be bad.

The skull has not yet been tempered, and if it hits a rock, the same head will bleed.

After rising more than ten meters, the momentum of the rise was exhausted, Ling Chen looked at a protruding rock, stretched out his hand and pressed it, and continued to jump up with his strength.

With the help of three times, Ling Chen finally saw the cave he had expected.

The cave is not big, it is also more than a meter wide and four or five meters high, and above the cave, there is indeed a whole rock.

With his palm at the mouth of the cave, Ling Chen jumped into the cave with his strength.

It is as tortuous as the cave below, and every ten meters or so, there is a big turn.

After turning five or six times, Ling Chen suddenly noticed a faint light in front of him.

Ling Chen sped up and turned two more turns, his eyes lit up.

Actually, it's not that bright, it's just that I spend too much time in the dark, and my eyes are extremely sensitive to light.

The light came from a square space more than ten meters away, about five meters in length, width and height, and the square space seemed to be filled with white mist.

But Ling Chen knew that it was not a white mist, but the aura in the square space was extremely dense, and the light produced by the energy particles colliding with each other.

Ling Chen was now sure that the place where the square space was located was the spiritual energy center of the Weaving Cave!

Underneath the square space, there is definitely a small spiritual jade mine!

Ling Chen knew that the Spirit Jade Mine, where every sect in the Ancient Martial Realm was located, there were Spirit Jade Mines underground, but the size and quality of the Spirit Jade Mines were different.

What Ling Chen couldn't understand was how the aura in the square space could be dense enough to emit light.

Ling Chen had been to the place with the most dense aura, which was Wanxi in Sanssouci Valley, but at that time, he couldn't feel Wanxi's aura at all!

Ling Chen had never heard of the energy particles being so dense that they would collide with each other and glow!

The energy particles in the center of the Weaving Cave Spiritual Qi glow, which does not indicate how big and high the quality of the spiritual jade mine is underground, but that square space is dedicated to collecting spiritual energy!

Otherwise, although the aura outside the square space is also dense, how can there be no light at all?

However, is there a means to collect aura?

Ling Chen had never heard of it, and if there were, condensing the aura would not be so important.

The aura in the square space, as long as it can sense the existence of the aura, will break through the transformation realm within a day if you put it in!

For example, the full moon, she is already able to move energy particles, as long as she enters the square space, she can break through in half a day at most!

And Ling Chen, with his qi sense and spiritual power, even if his true qi was completely exhausted, in the square space, he would be able to recover all of them in less than twenty minutes!

Looking directly at the square space that emitted a faint light, Ling Chen swallowed.

If you go into the square space to refine the tailbone, I'm afraid it won't take five days for Brother Chen to break through the peak of the mid-stage transformation of strength!

Thinking in his heart, Ling Chen's feet also walked uncontrollably towards the square space.

Even now that his true qi had returned to its peak state, he wanted to go in and feel what it was like to be surrounded by aura.

But as soon as he approached the square space, it was as if something formless and insubstantial was blocking him, and at the same time, his spiritual power also fluctuated violently!
