Therefore, Zhou Sui generously imparted this top-tier demonic cultivation technique to Ji Bingyu, Mu Ziyan, and Xia Jingyan, hoping that they would also greatly benefit from it.
Upon hearing this, Mu Ziyan immediately wore a bitter expression: "Husband, this technique is just too difficult to master. Even after practicing for half a year, I've only just begun to understand it."
Her expression was like that of a struggling student trying to learn calculus; she looked very distressed.
He had already exhausted all his strength just to get to the basics of this technique.
"That's right. This technique is at a very high level. To reach a proficient level, it's impossible without several years of practice."
"However, this technique is indeed incredibly useful. Now it's almost impossible for other cultivators to see through our cultivation level, unless a Foundation Establishment cultivator makes a move."
"I wonder where my husband got this skill from."
Ji Bingyu sighed with emotion, the more she practiced this technique, the more she felt its profoundness, even surpassing her own Ji family's Gengjin Sword Technique.
Moreover, if you really encounter danger, you can use this technique to change your appearance, so your enemy won't be able to find you.
"It's all passed down from our ancestors, all ancestral techniques."
"Now that you've entered the path, all that's left is to cultivate step by step; there's no need to rush."
Zhou Sui smiled slightly, not intending to explain anything.
...
Several days later.
In the quiet room, after several days of arduous cultivation, Zhou Sui sensed that the true energy within his body was constantly increasing, almost reaching the peak of the fourth level of Qi Refining.
Suddenly, he felt a surge of inspiration and realized that now was the perfect opportunity for a breakthrough—a chance that should not be missed.

At this moment, he picked up a pot of spirit wine and drank it down, making gurgling sounds.
He felt that spirit wine was more effective than pills and had no toxicity. The energy contained in a pot of spirit wine could also help him break through his bottleneck in one fell swoop.
Immediately, the spirit wine entered his stomach.
A surge of pure spiritual energy instantly flowed into his entire body, into every limb and bone.
Zhou Sui immediately activated the Gu nerve, guiding the spiritual energy to circulate throughout his body, completing one cycle after another.
The five major Gu worms—the Passionate Gu, the Dream Soul Gu, the Wine Worm, the Doppelganger Gu, and the Book Gu—are also located in his heart, brain, stomach, and other parts of his body, breathing freely and absorbing the spiritual energy between heaven and earth.
They are like individual dantian (energy centers), absorbing large amounts of energy and constantly strengthening their bodies.
"Is this the mystery of the Gu Jing Shen?! It is indeed infinitely mysterious."
Zhou Sui was very excited. He felt that his connection with the five Gu worms in his body had become closer. It seemed that he had reached the state of oneness with the Gu, as if the Gu worms themselves were part of his body.
Now he has also begun to realize the power of the Gu nerve.
This technique allows one to control, manipulate, and even fuse with Gu worms.
The cultivation of Gu worms is equivalent to the cultivation of the physical body.
Undoubtedly, the more Gu worms one controls, the stronger one's power will be. One can even use the power of Gu worms to help one quickly improve one's cultivation.
Ordinary cultivators can only store their true essence in their meridians and dantian.
However, those who cultivate the Gu Nerve can place their true essence and spiritual power into the Gu worms.
Each Gu worm is like a dantian (energy center) or sea of qi.
This also made his true essence power several times stronger than that of cultivators of the same level, practically on a completely different level.
Splash splash~~
As Zhou Sui silently comprehended the mysteries of the Gu nerve, the five Gu worms seemed to form a perfect spiritual energy cycle, with a vast amount of spiritual energy constantly flowing within his body.
His aura also expanded rapidly.
After circulating the energy for a full 108 cycles, the spiritual energy within his body reached its peak.
Boom~~
The next second, Zhou Sui sensed that his soul and body resonated, and a huge amount of spiritual energy instantly broke through the bottleneck in his body and opened up one of his meridians.
This happened naturally, without much hindrance.
Qi Refining Level 5!
Undoubtedly, after half a year of arduous training, coupled with the aid of the spirit wine, Zhou Sui finally broke through a minor bottleneck, thus raising his cultivation level to the fifth level of Qi Refining.
At this moment, he sensed that the true energy within his body had increased by one-third compared to before.
At the same time, his muscles, meridians, bones, skin, and internal organs were all tempered by the immense spiritual power, allowing his body to reach another level.
After advancing to the fifth level of Qi Refining, his strength more than doubled.
Splash splash~~~
A vast amount of true energy circulated continuously within his body, and his aura rose steadily, causing cracks to appear on the ground, resembling spider webs.
"It's done."
At this moment, Zhou Sui opened his eyes and revealed a joyful expression.
Meanwhile, Ji Bingyu and Mu Ziyan, who were waiting outside the quiet room, also sensed Zhou Sui's aura. They exchanged glances and felt extremely excited.
"It's a success! My husband has indeed successfully advanced to the fifth level of Qi Refining."
"It's only been a little over a year, yet he's already advanced from the first level of Qi Refining to the fifth level. His cultivation speed is too fast."
"It is indeed very fast; even the legendary top-grade spiritual root is no more than this."
"If you continue to cultivate at this rapid pace, perhaps your cultivation level will surpass ours."
Both Ji Bingyu and Mu Ziyan were extremely excited and deeply moved.
They had lived with Zhou Sui all along, so they naturally knew just how astonishing his cultivation speed was.
He had never left home, nor had he encountered any extraordinary events; he had only practiced asceticism, yet he had reached this level.
If this were to get out, it would terrify countless cultivators.
They wouldn't have believed such an absurd thing if they hadn't witnessed it with their own eyes.
With a click, Zhou Sui walked out of the quiet room, looking refreshed and full of joy.
After all, advancing to the fifth level of Qi Refining means that he is not far from the ninth level of Qi Refining.
Even for someone like my parents, if they wanted to advance to the fifth level of Qi Refining, they would have to be at least in their forties.
But he's only nineteen years old.
Even in a sect like the Immortal Cloud Sect, reaching the fifth level of Qi Refining at such a young age would qualify someone as an inner disciple.
It wouldn't be too much to even become a true disciple.
