Ling Chen retreats in horror, and his face is a little pale.

Just close to the square space, in fact, he didn't suffer any physical damage, just because his mental power fluctuated violently, which made him jumpy.

Ling Chen stands and stares at the square space. The shock in his heart is just like the ripples on the water. It's getting bigger and bigger.

He had already vaguely guessed what the square space was made of.

Invisible and immaterial, but can block the aura into the square space.

There is no physical attack, but it can cause his mental fluctuation.

If you're right, the square space should be related to mental power.

Mental barrier?

When he was in ancient martial arts, Ling Chen had heard that some of the top masters in the late Hunyuan period were so powerful that it was hard to imagine that they could release their mental power to form an intangible mental barrier.

For example, if a Hunyuan master talks to someone but doesn't want to let others know, he can use his mental power to block the sound.

But even the most powerful Hunyuan master can never seal up the aura with the mental barrier. There is no such legend in the ancient martial arts world!

The mental barrier set at the peak of the late Hunyuan period can not cause other people's mental fluctuation!

If the square space is made of mental barrier, the people who build it Ling Chen is not sure if it's human The mental strength is terrible!

Far above the peak of Hunyuan later period!

Ling Chen doesn't know how far away it is from the peak of Hunyuan's later period, but he believes that it's hard to build such a square space even if ten peaks of Hunyuan's later period release their mental energy at the same time!

What's more incredible is that the owner of the square space is not here. The aura in the square space is so dense that it shines. It should be many years since the owner left, but the mental barrier can still be maintained!

This should not be an ordinary mental barrier, I'm afraid it's mental solidification!

The spirit solidifies, the ancient martial arts world does not have this view, only Ling Chen guesses after contacting the square space.

Can human spirit be strong to this extent?

Even Ling Chen's spiritual strength is far beyond that of the martial arts of the same level, but he thinks that even one day when he reaches the peak of the later Hunyuan period, he can't build such a square space that can seal up the Aura!

I'm afraid that the aura within a few hundred Li can be easily condensed when the spiritual power is so strong!

Under the Zhijing cave, is there really Lingyu mine?

Previously, Ling Chen believed that there was definitely a Lingyu mine under the Lingqi center, but now it seems that Lingyu mine may not exist.

Maybe, it's just that the master gathered the aura within a few hundred Li and sealed it up.

With the terrifying spirit of the host here, it can really be done.

Looking at the dense aura in the square space, Ling Chen was envious and salivated, and once again approached the square space carefully.

This time, Ling Chen didn't rush in. He reached out and touched it first.

There is no feeling at all, but the square space obviously begins to deform under the touch of the palm. The naked eye can see that the square space is concave in.

Ling Chen retracts the palm, square space immediately restores the original state.

Square space does not have physical attack.

However, it is impossible to break the square space with the palm.

Ling Chen tries to bring out the aura in the square space, but his mental power moves. The solidified mental power in the square space immediately affects his mental power, and his mental power fluctuates violently again.

Ling Chen felt palpitation and shortness of breath, and immediately stopped working.

Ling Chen's face shows the color of shock again, too powerful!

He can't break the mental barrier that has been solidified for many years!

This is a master of his mental strength comparable to Dan Jin. If he is changed into another warrior, his mental strength may be directly destroyed due to the influence of solidifying mental strength barrier!

Mental power is very important to martial arts. Once the mental power is completely destroyed, the road of martial arts will be broken. Never say, people will become dementia!

What a terrible mental barrier!

After a few minutes, Ling Chen calms down.

The aura in the square space is really very dense, but if you can't enter the square space, it's nothing to look at.

Besides, the aura density outside the square space is enough for him to finish refining his tailbone in advance, so there is no need to stare at the aura of the square space.

Make a decision, Ling Chen backed out, stay here, looking at the square space in the thick aura and can't absorb, is a kind of torture.

In the next few days, Ling Chen was refining his tailbone in the dark cave.

It can be tempered four to five times a day. After a few days, more than half of the whole tailbone has been completely jade, and periosteum and bone have been replaced by aura.

On the fourth day, Ling Chen went out, and the dry food he had brought had been eaten.

At the beginning, he was preparing to refine his tailbone in Zhijing mountain. There was no lack of food in the huge Zhijing mountain, but when he entered the Zhijing cave, his food depended on dry food.Ling Chen didn't delay much outside. To make up for the demand, she bought a ticket to enter Zhijing cave again and came to the cave in the canyon.

The middle part of the tailbone is thicker than the edge part, and the quenching process is a little slower, but on the tenth day, the whole tailbone presents a transparent state.

Ling Chen spent another day to consolidate the refining results, and finally, it took 11 days to complete the tailbone refining!

As for the quenching effect Perfect!

The whole tailbone, if taken out, is a jade of high quality, but its toughness is far beyond any jade.

Lingchen's Qi and blood not only increase in quantity, but also differ greatly from the original in quality!

Of course, his spine hasn't been tempered, and his Qi and blood haven't completely changed, but even so, his upper limit of mental power has been greatly improved.

The increase can't compare with Shen Jingjing and Xiao Min's full moon. They bring him more mental strength, but it's more than the total of quenched ribs and sternum!

"It's a pity that the time of the martial arts competition is a little earlier, otherwise, brother Chen will harden his spine again!"

"In less than a month, brother Chen broke through from the middle stage of Huajin to the later stage of Huajin, and asked if you were satisfied with it!"

"Brother Chen specializes in all kinds of diseases!"

"If we break through to the later stage of Huajin, Fu Huichang wants to kick brother Chen again, it won't be so easy!"

However, even if the time is enough, Ling Chen is not willing to quench the spine immediately.

The tailbone is perfectly tempered, the Qi and blood have a tendency of qualitative change, and the upper limit of mental power has also been greatly increased, which can split the aura into smaller parts and control the power more.

At that time, we'll refine the spine and vertebrae again. The effect of tempering is better and it's easier.

Give up the idea of refining the spine and vertebrae, Lingchen continues to absorb aura, and let his true Qi return to the peak state.

With the completion of tailbone quenching and the expansion of true Qi capacity, Lingchen officially broke through the peak of Huajin in the medium term!

However, Ling Chen didn't leave in a hurry. Instead, he went to the square space.

Now that the upper limit of mental power has been raised, he wants to try again to see if he can enter the square space.

If you can, next time I will be arrogant again, I will break through the later stage of Huajin in ten days!
