After checking the condition of tailbone tempering, Ling Chen was still very satisfied.

It is dense, tough, even, and the tailbone is like breathing, swallowing and spitting the spiritual energy around the bones.

Of course, from the appearance, unlike the translucent effect when the ribs were quenched for the first time, it was just a bit jade-like at the edge.

But Ling Chen had long been mentally prepared that the tailbone was a whole piece, which was much thicker than the ribs. Even if he had the true energy of a psychic master and the mental power of a divine master, it was impossible to temper the tailbone into a translucent state after the first tempering.

In fact, even those geniuses in the ancient martial arts world will take at least three months to temper the edge of the tailbone into jade!

And Ling Chen only took him for a long time!

His mental power was exhausted, and a wave of fatigue came. Ling Chen took out his cell phone and looked at the time. It was already past two o'clock in the afternoon. He ate some dry food he brought and rested on the spot.

When I woke up, I could no longer hear the noise of tourists outside, and the lights in the scenic area were turned off. I looked at my phone and it was almost seven o'clock.

At this time, no tourists were left in the Zhijing Cave. The Zhijing Cave with hundreds of thousands of square meters was only Ling Chen left at this moment.

If it were in the past, Ling Chen was not afraid of being in such a dark place alone, but now he is a master of Huajin and has been alone in the back mountain of Xueshi Mountain for more than ten days. He has been used to loneliness and is not scared at all.

The mental power is restored, and there is no rush to absorb spiritual energy.

The cave where he is now should not be the center of the spiritual energy of the Zhijing Cave. When he condensed and absorbed the spiritual energy, the energy particles outside the cave flowed back, but more supplements came from the depths of the cave.

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

Taking advantage of the faint light of the mobile phone flashlight, Ling Chen walked deep into the cave.

As he expected, the spiritual energy deep in the cave was denser than outside. It was probably because some energy particles penetrated into the surface through the cracks in the rock formation.

The cave was winding and twisted, sometimes wide and sometimes narrow, and walked more than a hundred meters inside, and Ling Chen suddenly stopped.

In front of me is a whole rock wall, and there is no way to go.

Ling Chen frowned, and a look of confusion appeared in his eyes.

The caves are full of ordinary rocks, and there is no possibility of energy particles. The rock walls ahead also have no energy. Where does the spiritual energy in the Weaver Cave come from?

Ling Chen shook the flashlight of his phone upwards, but the faint light could not be seen at all.

After turning off the phone, Ling Chen did not continue to explore.

He came to Zhijing Cave to temper his tailbone. He was not interested in adventure. Now the spiritual energy here is rich enough, very close to the Wanxi River in Wuyou Valley.

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

When the mind method was activated, Ling Chen suddenly turned into a large magnet with super magnetic force, and the energy particles in the cave instantly absorbed around him.

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

The spiritual energy really comes from above!

After about ten minutes, there were very few energy particles flowing back from the cave outside, and Ling Chen also sensed that the energy particles in the cave came from above the head, at an altitude of about fifty meters!

The air cannot produce energy particles. Ling Chen judged that there should be a cave about fifty meters above the entire rock wall in front of him, which should be not far from the center of the spiritual energy of the Zhijing Cave.

Ling Chen was not in a hurry to go up, so he calmly absorbed spiritual energy on the spot.

Two hours later, Ling Chen's true energy returned to its peak state.

He took out his cell phone and turned on the flashlight, swayed above his head, and Ling Chen suddenly stepped into the air!

He had no interest in exploring, but how could he be willing to not go to see the spiritual center of Zhijing Cave?

With Ling Chen's current strength, he would not fly to a height of fifty meters in one browse. Besides, he would not dare to jump up with all his strength. If he hits a rock or something on his head, it would be bad.

The skull has not been tempered yet, and if it hits a rock, it will be like a head that will break blood.

After rising by more than ten meters, the momentum of the rise was declining. Ling Chen pointed at a protruding rock, reached out and pressed it, and continued to leap with the force.

After leveraging his strength three times, Ling Chen finally saw the cave he had imagined.

The cave is not big, it looks like it is more than one meter wide and four or five meters high. Above the cave, there is indeed a whole piece of rock.

With his palm on the entrance of the cave, Ling Chen leaps into the cave with his strength.

It is as twisty as the cave below. Every time you walk more than ten meters, there will be a big turn.

After turning five or six times, Ling Chen suddenly found a faint ray of light ahead.

Ling Chen speeded up and turned two more times, his eyes lit up.

Actually, it’s not that bright, it’s just that I’ve been in the dark for too long and my eyes are extremely sensitive to light.

The light comes from a square space more than ten meters away, with a length, width and height of about five meters. The square space seems to be filled with white mist.

But Ling Chen knew that it was not white fog, but the light generated by the dense spiritual energy in the square space and the energy particles colliding with each other.

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

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

Ling Chen knew that Lingyu Mine was located in the site of every sect in the ancient martial arts world. There was Lingyu Mine underground, but the size and quality of Lingyu Mine were different.

What Ling Chen couldn't understand was how the spiritual energy in the square space was so dense that it emitted light.

Ling Chen had been to the most densely packed place of spiritual energy, which was Wanxi in Wuyou Valley, but at that time he could not sense the spiritual energy of Wanxi!

Ling Chen has never heard of the energy particles that can be dense enough to collide with each other and shine!

The energy particles in the center of the spiritual energy of Zhijing Cave are shining, which does not mean how big or high the underground spiritual jade ore is, but that square space is specially used to collect spiritual energy!

Otherwise, although the spiritual energy outside the square space is also very dense, how could there be no light at all?

But is there any means to collect spiritual energy?

Ling Chen had never heard of it. If there were any, it would not be so important to condense spiritual energy.

As long as the spiritual energy in the square space can sense the existence of spiritual energy, it will break through the realm of transformation within one day!

For example, in the full moon, she can 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 sense of energy and mental power, even if all the true energy is exhausted, he can recover in a square space in less than twenty minutes!

Looking straight at the square space emitting a faint light, Ling Chen swallowed.

Rub, if you go into the square space to temper your tail bones, it will probably take you five days before Brother Chen can break through the peak of the mid-stage Huajin!

Thinking in his mind, Ling Chen walked towards the square space without being controlled.

Even though his true energy has returned to its peak state, he still wants to go in and feel the feeling of being surrounded by spiritual energy.

But as soon as he approached the square space, he seemed to have something invisible and intangible that blocked him, and his mental power also fluctuated violently!
