After everything on Lingdao was completed, Master Zhiyang immediately returned to Taizhen Sect, and then found a few close friends to start consulting a large number of classics.

After more than ten days of searching, I finally found an ancient book on the seal of the boundless sea stored in an inconspicuous corner of the sect's secret place.

It not only records various things about the seal of the boundless sea, but also mentions the origin and inheritance of Tai Zhen Sect.

It turns out that in ancient times, after defeating the ancient demons and sealing the demonic energy, the Taiyi Sect, the righteous sect of the Jin Dynasty, sent some of its disciples to Tiannan to establish the Taizhen Sect.

Their mission is to guard the seal of the boundless sea, but too much time has passed, and the Taizhen Sect has long lost contact with Dajin, and their inheritance of skills has long become its own line.

As for the mission of guarding the seal, they had forgotten about it.

Fortunately, through the records in the classics, it is indeed confirmed that the Demonic Abyss is basically as Xiao Yu said, and there are great safety risks. If not dealt with, it will definitely endanger the entire Tiannan.

So Master Zhiyang found Xiao Yu and Wei Wuya and told them about the matter, and all three of them paid great attention to it.

A large number of formation masters were immediately summoned, and under the leadership of several formation masters, they began to study various matters for repairing the sealing formation.

After more than half a year of non-stop research and experimentation, a large number of magic formations were finally deployed on Qiling Island to reinforce the seals, and many formation flags and disks were refined, as well as replacements for the original suppression formation eyes.

Since the formation eye is at the bottom of the Demonic Abyss, others cannot enter, so the task of reinforcing the formation eye naturally falls on Xiao Yu.

Naturally, Xiao Yu would not refuse. He came to the bottom of the Demon Abyss again and placed several sparkling formation disks under the stone tablet of the altar.

After burying the formation plate, Xiao Yu left the avatar here to practice, and then he returned to Fengling Island.

On this island, Xiao Yu opened up a cave that covers an area of ​​dozens of acres, with all the necessary warehouses and functions.

In the medicine garden, Xiao Yu transplanted all the spiritual herbs that needed to be ripened here, including Qixialian and the spiritual herbs needed to refine Jiangyundan.

It has been more than half a year since I came out of the Devil's Valley, and the elixir brought out from there has been ripened by Xiao Yu.

After some skillful alchemy work, Xiao Yu refined all the ripe elixirs into elixirs. Then he left the cave on an unnoticed night and went straight into the abyss of evil energy.

Next, he will practice in seclusion there, and all the work in the cave will be handed over to the incarnation of Sha Dan, a model worker, including ripening elixirs, taking care of spiritual insects, or receiving possible visitors, etc.

As for the security work of the cave, Xiao Yu arranged for Lei Yunqi and Blood Jade Spider, and gave them orders not only to kill or capture possible Xiaoxiao disciples, but also to monitor the incarnation of the evil pill.

Once the incarnation was found to have left the spiritual island without permission, he was immediately captured. Because Xiao Yu gave the purple gourd to the incarnation of the evil pill and he was not in the cave for a long time, this was considered a precautionary measure.

…

At the bottom of the Demonic Abyss, there was as much demonic energy as ever, and there was nothing else but an altar.

When Xiao Yu came in here again, he found that in a restricted shield beside the altar, the avatar was currently practicing in a posture specifically used for body training in the Brahma Saint Heavenly Demon Kung Fu.

Large waves of demonic energy around him were constantly washing into the body of the incarnation, and his face showed an expression of extreme pain.

"Uh ah..." Suddenly, a low roar came from the incarnation's throat.

Xiao Yu was startled and immediately moved over to see the situation.

But after the incarnation roared, he stopped practicing, his expression relaxed, and Xiao Yu also stopped.

After a while, the incarnation finished his power and slowly opened his eyes, wiped the big beads of sweat on his forehead, and said to Xiao Yu:

"I'm fine. I suggest you try practicing here!"

"Oh? What did you find?" Xiao Yu asked curiously.

"Do you still remember those techniques in the Brahma Saint Body Refining Technique that use pure spiritual power to infuse the body?" The incarnation did not answer directly, but asked rhetorically.

"Of course I remember, but because I don't have a spiritual environment that meets the requirements, I haven't practiced this magic formula specifically used to improve the physical body for a long time. Another reason is that the Brahma Saint Heavenly Demon Skill is a dual cultivation method of the physical body. It improves the magical power.

At the same time, the physical body also strengthens." Xiao Yu said calmly.

"Haha, of course I know these reasons, but in the past few days, on a whim, I tried to practice these techniques with demonic energy. The effect is surprisingly good. You will know after you try it." The incarnation smiled, looking very serious.

Looking satisfied.

"Oh? Since you said so, I have to give it a try." Xiao Yu felt itchy after being told by the avatar.

Immediately, Xiao Yu arranged a restriction on the altar that could filter some of the demonic energy, then took a posture inside and began to use the magic formula to infuse the body with spiritual (evil) energy.

"Hiss..." As soon as it started, Xiao Yu couldn't help but take a breath.

I saw that the liquefied demonic energy around him was so strong that after being filtered by the restriction, it surged toward Xiao Yu.

As soon as the demonic energy entered the body, it immediately washed away into the musculoskeletal cells, and then was eliminated from the body. This process was accompanied by a heart-wrenching drama, and even Xiao Yu, who had long been accustomed to pain, could not help but distort his face.

After a long period of time, Xiao Yu slowly finished the exercise, and then carefully realized the effect of the exercise.

"Huh? It really works!" Xiao Yu couldn't help but feel happy. With the sensitive perception of his spiritual consciousness, the strength of his physical body increased a little. Although it was very small and almost unnoticeable, it was still an improvement.

In this way, by using these demonic energies, you can improve your physical body to another level!

After seeing the effect, Xiao Yu immediately absorbed some of the demonic energy into his body and began to practice.

A few hours later, Xiao Yu's practice posture changed. After taking out a pill and taking it, he changed into the practice posture of the Brahma Saint and Heavenly Demon Kung Fu.

In this way, Xiao Yu began another retreat. He cultivated both his physical body and his magical power, and there were improvements visible to the naked eye every day. This feeling made him unable to stop.

…

Cultivation is timeless, and twenty-five years have passed in the blink of an eye.

Immersed in the pleasure of improving his cultivation every day, Xiao Yu could hardly feel the passage of time.

If it weren't for the fact that every few years, the incarnation would go out to the Demonic Abyss to eliminate the influence of the demonic energy on the body, and return to the cave to refine the elixirs needed for cultivation, he would not have known that such a long time had passed.

On this day, Xiao Yu, who was sitting on the altar with his body in a weird posture and surrounded by a lot of evil energy, formed a series of complex handprints like a phantom in his hand, and shouted in a low voice with a distorted face: "Broken!"

Immediately, his body shook silently, and an invisible wave of demonic energy quickly rippled around, awakening the incarnation practicing not far away. He looked up and looked at where Xiao Yu was.

With Xiao Yu as the center, the demonic energy on the entire altar began to stir, turning into thick pillars of demonic energy that quickly rotated and danced towards Xiao Yu.

The restraining shield that protected Xiao Yu was like a paper lake, shattered as soon as the demonic energy hit it.

Immediately, the demonic energy poured into Xiao Yu's body crazily, and the aura exuding from Xiao Yu's body suddenly increased a lot.

Surrounded by the demonic energy that was as dark as ink and invisible, a demonic figure dozens of feet tall suddenly appeared behind Xiao Yu.

The phantom had three heads and six arms, and was extremely terrifying. Its whole body was covered in gold and emitted a dazzling golden light, which penetrated through the heavy magic mist and illuminated an area of ​​hundreds of feet in radius.

As the demonic energy poured in, the shadow became clearer and clearer, and you could faintly see the appearance of the head in the middle, which seemed to be exactly the same as Xiao Yu's.

At a certain moment, the head suddenly raised its head to the sky and roared silently.

"Ouch..." Correspondingly, Xiao Yu felt that his cultivation had suddenly improved tremendously, and he couldn't help but scream up to the sky.

The roar was like thunder, rolling around and spreading out, passing over the altar, covering the Demonic Abyss, breaking out of the sealing light curtain, and heading towards the sea.

"Haha, late stage of Nascent Soul!" Xiao Yu murmured.
Chapter completed!
