The following night, Yao Hailei was studying the first layer of "Huangshi Jue".

"Huangshi Jue" is a set of cultivation exercises, divided into eight layers, the first four layers are the exercises of the cultivators, and the last four layers are the exercises of the immortals, which can also be called the real immortal methods.

The first layer of exercises mainly introduces the basic knowledge of condensing the true yuan power and some cultivation.

Regardless of the strength ranking of the immortal realm for the time being, the strength level of the cultivators in the human realm is divided into twelve layers, in order: pneumatic, refining gods, dancheng, fetal breath, primal infant, distraction, out-of-body, transformation, fusion, returning to the void, primordial spirit, and heavenly tribulation.

The first four layers of the Huangshi Jue are the early, middle, and late stages, corresponding to the twelve realms of the cultivator.

Among them, the pneumatic period is the most basic realm, in this realm, it is necessary to perceive the existence of the aura of heaven and earth, so as to absorb the aura into the body and condense the true yuan force.

When you cultivate to the point where you can release the true yuan power out of your body and condense it, you have reached the peak of the pneumatic period, that is, you can sprint to the god refining period.

Although it is not necessary to sit cross-legged to practice, the exercises also specifically indicate that it is best to sit cross-legged, so that the body can maintain the best absorption in the aura.

Because there were still Chen Zuoheng and Liu Yuwei in the room, Yao Hailei didn't dare to sit up and practice cross-legged directly, so he didn't directly practice "Huangshi Jue", but planned to start practicing after the trip was over and returned home.

Anyway, he is the only one in the family, so he doesn't have to worry about being discovered.

※※※※※※※※※※※※※

Soon, three days later, the crowd was on the return train.

Looking at the gradually faring Huangshan Station, Yao Hailei sighed with a complicated expression, put his hands in his pockets, turned around and walked back into the carriage.

Perhaps, in the future, after he has achieved success in cultivation, he will come back again.

※※※※※※※※※※※※※

"Huh, I'm finally back!" Yao Hailei looked up at the sky above Jiaxing, and an indescribable excitement suddenly surged in his heart, perhaps because he understood that when he returned home, his life would be turned upside down.

After saying goodbye to Chen Zuoheng, Liu Yuwei and several classmates who had a good relationship, Yao Hailei boarded the bus and returned home directly.

He had only been away from home for five days, but when he returned, he felt as if he hadn't been back for centuries.

Yao Hailei didn't say much, put the suitcase in the corner of the wall, and walked into the toilet while taking off his clothes.

According to the "Huangshi Jue", when he cultivates for the first time, the magazines in his body will be expelled from the body, although his current physical body is transformed by the Divine Tree, but just in case, it is better to take off all his clothes.

He took off all his clothes, sat cross-legged on the floor of the toilet, and took a silent breath, trying to calm the tension, excitement, and exhaustion in his mind.

It wasn't until he finally calmed down completely that he breathed lightly, trying to follow the content of the "Yellowstone Jue" and began to perceive the aura around him.

At first, he vaguely felt a trace of irritability, but as time passed, his whole person seemed to fall into an ethereal realm.

For example, many people go to bed and feel like they can't sleep at first, but end up falling asleep inexplicably.

Yao Hailei is like this now, unconsciously, his whole person has fallen into this ethereal realm, and everything has disappeared from his consciousness, except for the original idea - perceiving aura.

Suddenly, Yao Hailei only felt as if he had sensed something, and slowly, a trace of cold gas entered his perception from all directions, touching his skin little by little, penetrating into his body little by little, and circulating in the meridians all over his body.

Every time these cold gases circulate through the meridians in his body for a week, a trace of extremely fine gases will be born.

This gas is different from the cold gases in the outside world that Yao Hailei perceives, and the gases generated in his body are as warm as water, flowing like fluid.

I don't know how long he sat there, but suddenly, he opened his eyes.

Blinking silently, he suddenly found that all the memories he had previously had in the ethereal realm had disappeared at this moment, and no matter how much he thought about it, he couldn't remember what he had felt just now.

Just when he was secretly strange, he suddenly felt a cold feeling on the surface of his body, and when he looked down, he saw that there was some pale green substance on the surface of his skin.

Looking at these substances curiously, Yao Hailei smiled and said, "Sure enough, there are impurities!" Hehe, fortunately I had the foresight to ......" As he spoke, he wanted to get up and use the faucet to flush these substances.

Suddenly, the voice of the blue sword rang out: "Wait, master, these are not impurities, but the essence of wood in the sacred tree!"

Yao Hailei was slightly stunned, and said suspiciously: "The essence of wood?"

Bi Lianjian sighed and said, "Yes, these wood essences are the essence of plants, but you are now a human body, so it will be automatically forced out of the body because of your cultivation, in my memory, if you use these substances to refine the elixir, you can improve the quality of the elixir!"

Yao Hailei whistled and said with a smile: "Good things! Fortunately, they haven't been washed off, hmm, but how can I collect them? Do you scrape them off with your hands?"

Bi Lijian smiled and said, "Don't you have life energy, wrap these substances with life energy, and then find a bottle to fill them, by the way, you must have a jade bottle!"

Yao Hailei almost fell, and said angrily: "What did you say? Where did I buy a jade bottle, uh, by the way, I remember that my mother used to keep a jade bottle...... Wait, let me collect these first. ”

As he spoke, his heart moved, and streams of pure green energy suddenly surged from his heart.

Yao Hailei looked at these energies excitedly, and after a few days of experiments, he was also able to use them more proficiently.

Following his thoughts, the life energy quickly wrapped these wood essences, and then gathered the wood essences together, and just walked out, walked into the room and rummaged through.

Five minutes later, he finally found a jade bottle, carried the bottle to the toilet and rinsed it with water a few times, and washed it several times with life energy before he put the essence of wood in it and put it on the table next to him.

"Master, you seem to have succeeded in condensing the true yuan power! Yao Hailei smiled, closed his eyes, and sensed the situation in his body.

After a moment, he stretched out his hand, and suddenly a bright light appeared from his palm.

Yao Hailei said excitedly: "Great, sure enough, the condensation has been successful, but it can't be released out of the body yet, it's probably the early stage of pneumatics!"

"Haha, in the middle stage, you can release it from the body, but the true yuan power will soon dissipate, and only in the late stage can it be condensed for a long time......

Bi Lijian grinned and said, "Master, since you have successfully cultivated the True Yuan Force, then you can use the 'Qiankun Realm'!" Yao Hailei nodded and said with a smile: "Yes!"

In the past few days, Yao Hailei asked the Bi Ling Sword to pass on to him several spells that could be used during the pneumatic period, which were the four spells of Qiankun Realm, *, Eye Condensation, and Gold Chopping Technique.

The Qiankun Realm can carve out a space that belongs exclusively to the cultivator himself, allowing him to store items, which can be living or dead, but the size of the Qiankun Realm is related to the strength of the user.

According to the introduction of "Huangshi Jue", it seems that this Qiankun realm is actually the initial use of the inner universe, but with the use of cultivators, the size of the inner universe that can communicate will also change, which is the reason why the size of the space will change.

*, eye gaze, and alchemy are all relatively common Taoist techniques.

* It is a thunderbolt emitted from the palm of the hand, which has a great effect on creatures such as ghosts.

Eye gaze is a clairvoyant-like spell that improves a person's vision.

Alchemy is the use of true element power to condense on the surface of the body, so as to reach the point of slashing gold like mud.

Regarding the inner universe, Bi Lian Jian didn't find many records in the memories of the Huangshi Sanren, after all, when absorbing the soul, the memory will only be partially absorbed, and Bi Lian Jian just remembered the "Huangshi Jue", and his luck was already very good.

After some experiments, Yao Ruoyu excitedly put the jade bottle into the Qiankun Realm, then put on his clothes, sat back in the room, and began to cultivate.
