Walking to the fourth room at the end of the passage, there was finally no one.

In fact, this is also reasonable.

If there were people in the four heaven-level caves, why did Elder Sikong let him in?

When I walked to the bronze door, it was still closed, but it was empty in a groove in the door.

This is the criterion for judging whether there is anyone in it.

Ling Yi took out the blood-stained token and put it into the groove, and it was tightly sealed.

With a slight force on his palm, the token was slowly rotated by him, and he heard a click, and the closed copper door slowly opened.

It was only a crack in the door that was exposed, and the aura that came to his face almost washed Ling Yi away!

"This ......"

Ling Yi's pair of red fire pupils widened, and even the red fire in the spirit world was consumed a little more.

"That's too rich, isn't it?"

Although judging from the concentration of the aura in the Fire Cloud Wall, he had a rough psychological preparation for the level of aura in the heaven-level aura cave, he was still greatly shocked.

Is this still Reiki?

It feels like a pure internal force that has been tempered for thousands of years!

As long as you sit inside, even if you don't do anything, just keep breathing, the internal force in the dantian will soar, right?

Of course, this is also because his own cultivation is still low, in the eyes of a martial arts sevenfold master like Elder Sikong, it will not actually be such a terrifying increase.

But......

Just sitting in it?

When the bronze door was fully opened, Ling Yi felt as if he was too naïve.

Sit inside?

It's not too easy for him to walk in at this time!

Only then did he understand the reason why Elder Sikong would advise him to replenish the qi and blood in his body before coming to the Spiritual Qi Cave Heaven.

If the body is deficient in qi and blood, it can't withstand the huge pressure brought by this rich aura, right?

The heaven-level aura cave is rich in spiritual energy...... It's so rich!

It's so rich that it's almost condensed into substance!

Ling Yi stood at the door, obviously there was nothing in front of him, but he felt that there was a soft, but extremely resilient wall in front of him.

He tried to take a step into the door with his foot raised.

So he took two steps back.

Ling Yi never thought that one day he would be blocked by the aura that the martial artists relied on to cultivate.

Of course, in fact, he just meditated outside the door on the spot, and slowly absorbed the aura floating out of the door, which was enough to bring him great benefits.

But he worked so hard to come to the Heavenly Gate of the Heaven-level Spiritual Qi Cave, how could he do such a salted fish?

Of course you have to go in!

Ling Yi gritted his teeth, and his heart was ruthless.

To do it, he had to do it to the extreme, and he had to make the most of this precious cultivation time for the day!

The internal force was running wildly in his body, and Ling Yi seemed to have turned himself into a huge sharp cone, step by step, struggling to squeeze into the heaven-level spiritual qi hole.

Every step is deep in the ground, and only then can the other side stand firm and not be pushed out of the door again by the strong rebound force.

Fortunately, the aura is only an aura, there is no autonomous consciousness, and it will not resist Ling Yi, an alien species, so in the end, he still squeezed into the door.

Bang.

There was also a mechanism inside the door, Ling Yi got up and slapped it down, and finally closed the bronze door and left himself inside.

After this trip, he was already sweating profusely, and he was not pressed to run for two hours in the back mountains.

But when he looked back, he only walked into the door from outside the door, three steps before and after at most.

The rich aura oppressed Ling Yi even his facial expression was stiff, and under the strong pressure, how many beads of sweat oozed from his forehead were all squeezed into water vapor at the first time, and left his head in a distorted posture.

Ling Yi felt that what he was breathing was no longer air, but internal force!

The aura cave was not large, almost the size of his dilapidated courtyard.

There was nothing inside, the whole hall was an empty hall, and on the surrounding mountain walls, there was a fiery red light flickering.

It is from this that the aura comes from, and this is the place where the ancestors of the Scorching Sun Sect found the strongest aura in the wall of fire clouds, so as to dig out the cave sky.

Ling Yi didn't have obsessive-compulsive disorder, and he didn't choose to sit down when he walked to the center again, as long as it was within the cave sky, he was sticking to the wall, and the aura he could enjoy was exactly the same.

So he bent his feet, sat down directly on the ground, and regardless of whether his posture was standard or not, he directly began to enter the cultivation state.

After hesitating, the Cangyan Maha Mental Method, which had been sealed by him for a long time, still came out.

This is an excellent opportunity to cultivate, and it would be too wasteful to simply absorb the aura and transform it into your own internal force.

When the aura enters the body, it must be guided by the internal strength mind method to achieve the best effect, so this is also the reason why all martial artists want to practice the higher level of the internal strength heart method.

If the yellow-level internal power method can only transform the aura into half of the internal force, the Xuan-level internal power can achieve a one-to-one without loss, and although the earth-level is also a one-to-one transformation efficiency, the purity of the internal force is far from being comparable to the Xuan-level.

As for the heaven level, it can be created out of nothing, and one aura can be cultivated to the extent that two parts of internal force can be cultivated!

If Ling Yi simply swallowed the spiritual energy, or used his entry-level qi extraction refining technique to transform the internal force, it would take about ten parts of the spiritual energy to exchange it for one internal force.

Therefore, knowing that there was a risk of triggering the red fire by cultivating the fire attribute technique again, Ling Yi still decided to take a risk, no matter what, he also wanted to maximize the effect of this heaven-level spiritual qi cave cultivation!

Cangyan Maha got up, Ling Yi felt that his body was hot, and it seemed that even the pressure on his body had been reduced a lot, and the 36,000 pores on his body were all open at this time, frantically absorbing the aura in the cave sky!

Fortunately, his spiritual world was still stable, and Chihuo stayed honestly and did not jump out to make trouble for Ling Yi at this time, which made him feel a lot more relieved.

Soon, Ling Yi was immersed in a state of cultivation, and at this moment, it seemed that he was the only one left in the heaven and earth, sitting in a hole, absorbing the aura of heaven and earth.

Nothing else.

Since being reborn in this world, this was the first time that Ling Yi had truly let go of everything and was in an absolutely safe environment to concentrate on cultivation.

In this short one day, he can finally let go of all the ...... in his heart

Grievances?

Hatred?

Conspiracy?

Right and wrong?

All of these were left behind by him, and at this time he was empty-minded and entered a state of self-forgetfulness.

If Ling Yi's cultivation state at this time was seen by Elder Sikong, he was afraid that he would have to take another look at Ling Yigao.

Meditation and ethereal, self-forgetfulness!

This is the dream state that many warriors can meet but cannot seek!

Entering the state of self-forgetfulness, not only will the efficiency of cultivation increase significantly, but also you can gain a deeper understanding of martial arts.

This perception may not be able to experience the effect immediately, but it has laid a more solid foundation for Ling Yi's martial arts foundation, making his future martial arts path smoother!
