After crossing over, he has no taboos among the zombies.

Half an hour later, Qin He stopped in front of the entrance of a valley completely shrouded in thick black fog - he had arrived at the cave.

This is the lair of evil creatures. It has been sealed for many years and no night watchman has set foot here. It is much more dangerous and evil than other places.

At the entrance, one can hear the faint roar of evil creatures, and a strong smell of blood mixed with evil spirits hits you in the face. Ordinary cultivators may lose their minds just by getting close, let alone going in.

Qin He didn't care about it and walked straight in.

"Roar!"

As soon as they entered the devil's cave, two devil wolves with protruding fangs jumped out from the shadows, and their smelly saliva dripped onto the ground, corroding it into sizzling black spots.

Qin He did not stop, but just waved his hand casually, and a wisp of dark magic flame shot out from his fingertips, instantly wrapping up the two magic wolves.

A shrill howl sounded briefly and then disappeared immediately. Not even a bone was left of the demon wolf as it was completely devoured by the demonic flames.

The restless auras in the surrounding darkness immediately subsided a lot, and no one dared to show up easily for the time being.

Qin He continued to go deeper for more than ten miles before sitting down in a relatively dry corner of the rock wall.

He closed his eyes and no longer tried to suppress the demonic energy surging in his body. Instead, he began to actively guide this energy to flow through his meridians.

At first, the demonic energy rushed into the meridians with a violent force, causing dull pain.

But Qin He's mind was calm, and the insights he gained from smelting thousands of Daos, burning corpses to obtain rewards, and countless times looking back on his life, like the essence hidden deep in his soul, naturally emerged.

Although he has lost his supernatural powers, the truth is that the way of the world is simple and all things have the same origin.

The demons and evil spirits that he had slain, as well as the peerless demons such as the Source of the Supernatural and the Lord of the Supernatural, their control and use of demonic energy, were now clearly reproduced in his mind.

But in just a moment, the originally violent demonic energy became docile under his guidance, slowly seeping into the sea of ​​consciousness like a stream, and wrapping around his soul and Nigong Pill.

He finally regained full control of his body.

Looking inward, he could clearly "see" that the inky magic energy was like a light mist, entwining his transparent soul in strands, and at the same time slowly flowing on the inner wall of the Nigong Pill, as if weaving an invisible protective shield.

However, the evil thoughts hidden deep within the demonic energy also became restless. Like poisonous snakes hiding in the dark, they followed the trajectory of the demonic energy and drilled into his sea of ​​consciousness, trying to entangle and erode his original heart.

Qin He's expression became stern. He had already prepared a method to suppress the evil thoughts.

He thought of learning from the magic shell method of Mo Luo - although there has never been a complete method for this method, and no one has ever succeeded, he felt that this method was feasible after refining all the methods.

The so-called magic shell method is to use the magic power to refine a set of outer armor, use this magic shell to isolate the erosion of magic thoughts and protect the original source of clarity. Only in this way can one practice magic skills without any taboos.

He first condensed the magic power into countless fine silk threads and began to weave them on the surface of the soul. This is the inner magic shell.

This shell must fit snugly against the soul, like a second layer of skin, to isolate it from all external evil thoughts.

During the weaving process, waves of stabbing pains were felt in the soul, and the evil thoughts were like a swarm of crazy ants, constantly attacking the unfinished network cable, trying to tear a gap.

Qin He's determination was as firm as a rock and he remained unmoved.

He transformed the insights in his mind about how the peerless demon could stabilize his soul into an invisible barrier, suppressing his restless demonic thoughts while speeding up the weaving.

After an unknown amount of time, the inner demonic shell finally took shape. It was a light black, nearly transparent membrane that tightly enveloped the soul. Fine demonic patterns slowly flowed on the membrane's surface, like a living being breathing, blocking out any demonic thoughts that tried to approach.

Next, he began to cast the outer layer of the demonic shell. Using the Nigong Pill as a base, he mobilized the denser and heavier demonic energy and began to "pour" and compress it layer by layer onto the inner wall. This process was accompanied by a sharp, painful swelling sensation that felt as if the Nigong Pill was about to burst.

Qin He gritted his teeth, endured the discomfort, and continued to guide the magic power to repeatedly refine it, so that it gradually condensed from gaseous to solid. Finally, a layer of dark, hard shell wall was formed on the inner wall of the Nigong Pill, forming a perfect echo with the flexible magic shell inside.

When the last tiny gap in the outer magic shell was completely filled, Qin He suddenly opened his eyes, and a ray of clear light flashed in his eyes.

Looking inward, he saw a light black, flexible membrane covering his soul, and a pitch-black, hard shell within his Nigong pill. These two layers of demonic shells, like two impenetrable barriers, firmly guarded his essence at the center. His restless demonic thoughts collided with the shell walls, unable to even stir a ripple.

But at the moment when the double-layer magic shell was completely stabilized, a dull roar suddenly came from the sky above the magic cave!

Outside, the originally gloomy sky was suddenly covered by thick blood-red clouds. Dark red electric snakes were moving and darting in the clouds. The smell of blood in the air was so strong that it was nauseating. A terrifying pressure that far exceeded all the monsters before suddenly descended and enveloped the entire demon cave.

Qin He felt something in his heart, and a trace of vigilance flashed in his eyes - this was the bloody demonic calamity.

He did not dare to hesitate for a moment, and immediately tried his best to gather all the breath in his sea of ​​consciousness, suppressing the luster and fluctuations of the double-layer magic shell to the lowest limit. Even the magic power that naturally flowed around his body was deliberately restrained, retaining only the tiniest trace to maintain the existence of the magic shell.

He knew full well that now was definitely not the time to overcome the tribulation. This blood-colored demonic tribulation specifically targeted the souls of demon cultivators. With his demonic shell just forged and not yet stabilized, if the tribulation lightning locked onto him, his soul would be crushed, beyond redemption.

Fortunately, this bloody demonic calamity seemed to be only alarmed by the original fluctuations that leaked out at the moment when the demonic shell was condensed, and did not completely lock his specific location.

As Qin He completely restrained all his breath, the terrifying blood-red clouds in the sky began to slowly dissipate, the dark red electric snakes also disappeared, and the suffocating and terrifying pressure also receded like a tide.

Qin He finally relaxed when he sensed the demonic aura receding.

He raised his hand and gently pressed it between his eyebrows. He could clearly feel the hardness and stability of the magic shell inside the Nigong Pill, as well as the softness and density of the membrane covering the soul.

Two layers of barriers, one inside and one outside, complement each other and protect his origin tightly without any leakage.

The magic shell is done.
