Entering the inner vision, Shen Chong's mind quickly sank into the dantian.

In the past few days, he and Lu Xiang'er have repeatedly discussed, and finally came up with a way to alleviate the gray aura's attack on his Jindan. Today he came out alone to test.

In the vast sea of dantian qi, except for the Nine ** Dan slowly rotating, it was quiet at the moment.

Shen Chong waited quietly, but his mind didn't dare to relax for a moment, and he focused all his attention on the calm sea of qi.

After ten or so minutes, suddenly, the gray air flow burst out of the sea of qi without warning, like a fierce evil dragon, quickly swam around the golden pill, and after finding a position, it swooped towards the golden pill in the center of the sea of qi.

Under Shen Chong's gaze, the gray airflow collided with Jiu** Dan blatantly.

Jiu** Dan trembled violently, as if even the constant spin had been interrupted for a moment, and then, it resumed its original rotation state again. And that gray air current, after shattering into countless dust, slowly gathered, and reluctantly returned to the sea of qi to recuperate.

It's a bit of a bad situation.

Carefully observed the battle between the gray air flow and the Nine ** Dan in this round. Shen Chong's heart also began to sink slowly.

Because he found that the gray air current, although it still couldn't help the Nine ** Dan, but it itself was slowly strengthened in the process of damage and recovery again and again.

Compared with the inward view when he just woke up a few days ago, today's gray spiritual aura is obviously a little more condensed and stronger.

And his own Nine ** Dan is even bleaker than then.

Trade-off!

It seems that the attack of this gray airflow on Jiu** Dan is not as he thought at the beginning, and it really has no impact at all. I'm afraid that if this goes on for a long time, one day, my Jin Dan or Yuan Ying will really not be able to withstand the gray air current attack, and the tragedy of Dan shattering and dying may not be.

"Alas~~ I was still hesitating, but it seems that the gray air flow is also forcing me to use this method. Shen Chong shook his head helplessly, still maintaining an inward state, but his mind was divided into a part, and he sacrificed a milky white jade piece in his hand.

Nourished by the spiritual power in Shen Chong's hand, the jade piece floated into the air and emitted a faint white light. As Shen Chong recited the formula, some small mysterious characters slowly poured out of the jade piece, and then entwined and merged into Shen Chong's body.

In the jade tablet, a very cherished mantra is recorded - 'Heart Rock Mantra'. This is what Lu Xiang'er taught to Shen Chong, and it has the effect of sticking to one's own heart, resisting external forces such as spirit and spiritual power, and attacking one's own Jindan and Yuanying.

Xiang'er told Shen Chong that as far as she knew, no one in the Freshman Realm knew this spell, and even in this Yellow Spring Realm, the 'Heart Pan Mantra' was one of the most cherished and rare spells. At the beginning, when she was attacked by Liu Liang with the Xuanji Thunder Talisman, it was by relying on this spell that the Jin Dan in her spiritual body was only injured a little, but it did not hurt the root.

According to the characteristics of the 'Heart Rock Mantra', it was possible to help Shen Chong's Jin Dan resist the attack of a part of the gray air flow.

It's just that this 'heart mantra' also has side effects. That is, once it is unleashed, it is necessary to detach a part of the mind to keep it running. At the same time, the 'Heart Rock Mantra' will cause some spells that conceal the aura to become ineffective.

For example, Shen Chong's 'Hidden Spell' now.

Therefore, at the beginning, Shen Chong was not willing to give up the secret method of saving his life such as the 'Hidden Breath Mantra' for the sake of the 'Heart Rock Mantra'.

Now, after seeing the fierce performance of the gray airflow, Shen Chong finally decided to cut his love.

Without the 'Hidden Breath Spell', he still has a higher level of 'Profound Secret Technique' instead. Although Yu Kite had told him that the cultivation of the 'Secret of the Soul' was very difficult. But after all, the effect is better than the 'Hidden Breath Spell', once practiced, even the spiritual sense of the Yuan Infant Master can be concealed.

However, there is no substitute for the mantra of 'Heart Rock Mantra' for the time being.

These thoughts flashed through his mind, but there was a drastic change in Shen Chong's sea of qi.

Under Shen Chong's full urging, those milky white small characters struggled to pass through his body, and after a long time, they drilled into the sea of qi and slowly gathered around Jiu** Dan.

Those characters, after all, are foreign things.

Just the step of letting the characters gather around Jin Dan consumed nearly half of the Yuan Spiritual Qi in Shen Chong's body at once.

After the gathering was completed, all the milky white characters were connected end to end, forming several rotating white bands of light, enveloping the entire Jindan.

At this time, the sea of qi under Jin Dan seemed to be attracted by the tide, and after a period of ups and downs, a huge flow of nine-colored spiritual qi was suddenly pulled up by the white character light band. Then it automatically merged into the light band, and as the characters began to spin rapidly, slowly wrapping the entire Jindan in the middle, a process that lasted for several minutes. It will not end until the entire Jindan is covered with a layer of substance that resembles a protective layer.

Shen Chong was surprised in his heart, he couldn't imagine that this 'Heart Rock Mantra' was such a principle. No wonder it can resist part of the damage of external forces to Jin Dan and Yuan Ying.

Those white characters, after fusing the aura in the sea of qi, were actually on the outside of the golden pill or the yuan baby, forming an eggshell composed of aura. In this way, the aura eggshell induced by the 'Heart Pan Mantra' can act as a buffer, making the golden pill in the middle of the eggshell safer.

It's just that the direction of rotation of the outer eggshell is completely opposite to that of Jindan, and the two completely different rotation directions will cause small changes in the perfect trajectory of the original Jindan's rotation, which naturally makes the breath more difficult to hide and easy to be discovered.

During the time when Shen Chong was running the 'Heart Pan Mantra', the mysterious gray air flow finally finished recuperating and burst out of the sea of qi again.

This time, the gray air flow did not start attacking directly, but instead had a spiritual intelligence, swimming around the golden pill several times, as if curiously observing the aura eggshell of the strange outsider, the 'Heart Pan Mantra'.

In this way, after nearly ten minutes of quiet stalemate, the patience of the gray air flow was finally worn out. It writhed rapidly, bringing a churn of the sea of qi, and then, once again, it rushed in the direction of Jindan without fear of death.

"Bang!" In a crisp sound, even Shen Chong's dantian was shocked.

Under Shen Chong's nervous attention, the eggshell composed of aura air flow collapsed with a bang.

And most of the gray air flow collapsed, leaving only a small stream to pounce on the golden pill inside the eggshell.

It's just that Jin Dan's rotation direction is completely opposite to the eggshell, and in an instant, the small gray air flow that is weak behind it is torn apart.

This crash. Although the eggshell formed by the 'Heart Rock Mantra' collapsed, the Jin Dan was unharmed, and the gray mysterious air flow could be said to be completely defeated this time.

There have been countless collisions in Shen Chong's body, and there has finally been a turnaround from now on.

After a few breaths, the gray airflow finally slowly condensed, but the breath had withered a lot. And at this time, the layer of aura eggshell that protected the golden pill also resurfaced in the continuous operation of the 'Heart Rock Mantra'.

"Great! With this 'Heart Rock Mantra', one's own aura can penetrate the eggshell without being affected and come to the golden pill. But that mysterious gray air flow will be directly crushed. If the gray air flow wants to cause damage to Jin Dan again, the difficulty will increase several times at once!" Shen Chong was excited in his heart, and he couldn't help but clench his fists and excitedly withdrew from his inner vision.

It's just that his mind is still separated from a trace, and he is always maintaining the operation of the 'Heart Rock Mantra'.

The 'Heart Rock Mantra' can't just be stopped. Otherwise, it will take a lot of mind and nearly half of your own aura to restart every time, and it will be more than worth the loss.

Although the amount of aura required to activate the 'Heart Rock Mantra' is very impressive, once the spell is activated, it can rely on inertia and only a small amount of aura to maintain its operation.

For that bit of consumption, Shen Chong still doesn't care.

Successfully learned the 'Heart Pan Mantra' and temporarily solved the trouble of gray airflow, which made Shen Chong's mood a lot better.

He continued to guide his aura for several weeks before he began to recall the 'Secret of Darkness' taught by the rain kite.

He naturally attaches great importance to the secret method that can be hidden.

After hiding the breath, you can evade the pursuit of the strong, and you can also let yourself quietly lurk near the enemy, so as to achieve the effect of a sneak attack on the enemy with one hit. It can be said that a good concealment technique can definitely enhance the actual survival ability of a cultivator a lot.

From all walks of life in the mortal world, although there are countless cultivators. However, there are very few secret methods that can hide one's own aura.

Most cultivators, even if they have a sect inheritance, can obtain resources such as cultivation exercises, spiritual weapons, and pills, but they cannot obtain hidden magic techniques. After all, even their teachers didn't have such a precious secret method, so how could they teach it?

Cultivators who don't understand the secret method of concealment can only rely on reining in their own momentum and aura, and controlling their spiritual power without fluctuations, to achieve the purpose of hiding themselves. In this way, the hidden effect is not obvious, and it is impossible to escape the detection of some sensitive people, let alone hide under the spiritual consciousness of the master of the Yuan Infant Stage.

Shen Chong was still very lucky to be able to get the secret method 'Very Secret Secret' left by Xuan Yun.

With a long exhale, Shen Chong immediately discarded the chaotic thoughts in his mind, and according to the content of the mantra of the 'Secret of Darkness', he concentrated on guiding his spiritual power to run.

In the mountains and forests not far from Lijiazhai, on top of the huge black stone, Shen Chong sat safely. Suddenly, his body trembled violently, and beads of sweat the size of beans spread uncontrollably all over his body. If someone was by his side at this time, he could even hear it, and even the bones in Shen Chong's whole body were making a ** sound of "crunch~crunch~".

"I'll it!!" Shen Chong gritted his teeth and scolded in a low voice, and quit his cultivation in a bit of embarrassment.
