Inside it is the "Huanzhen Pill" that was recently refined.

He closed his eyes and meditated quietly, adjusting his breath. Thousands of thoughts in his mind rose and fell, and he gradually entered an ethereal realm.

"let's start."

Entering the ethereal state, Liu Yu thought about it, and the tenth level of Qingyang Gong started to work.

"Boom~!"

In an instant, an extremely powerful spiritual pressure swept away in all directions with him as the center.

This caused dust on the ground to rise and ripple in circles.

"Huhu~"

The first to ninth levels of Qingyang Gong correspond to the early stage of Qi refining to the late stage of Jindan, and the tenth level is the early stage of Yuanying.

Obtain the complete copy of "Qing Yang Gong" from "Kong Qing Zhenren".

In the past fifty years, Liu Yu has gone through the Immortal Mansion's deductions to improve the skills of the eleventh level of the Nascent Soul, and customized them for himself.

As the skill was running, the cyan aura on his face fluctuated.

The extremely pure magic power circulates in circles in the meridians, from slow to fast, and gradually faster and faster.

Wisps of mana appear in the Dantian after going through seventy-two cycles of the physical body.

Then in the Nascent Soul state, the remaining thirty-six great celestial cycles are carried out.

A total of one hundred and eight cycles were completed, and Liu Yu's already extremely pure mana was polished and refined.

Because the cultivation level has reached the peak of the early stage of Nascent Soul, there is no way to advance without breaking through the bottleneck, so the increase in mana intensity is minimal.

Using the technique at full power, time passed slowly, and before you knew it, ten days and ten nights passed.

In the blink of an eye, it was the early morning of another day.

"This is the moment!"

Liu Yufu reached deep into his mind, and when he felt that the opportunity for a breakthrough had arrived, he immediately accelerated his exercises.

"boom!!!"

Under the observation of his spiritual consciousness, he launched a brazen attack on the bottleneck in the mid-term. His whole body of mana was overloaded and the speed was far faster than normal.

Fortunately, Liu Yu's physical body is strong. Even if his magic power is overloaded, it will not cause damage to the meridians and can last for a long time.

When the mana speed increased to a certain extent, under Liu Yu's calm control, it suddenly moved towards a new meridian route.

This brand-new route is the Great Zhoutian Cycle of the eleventh level of Qingyang Gong, which is much more complicated than the tenth level.

Moreover, many meridians have not been opened, and there is still an invisible force blocking it.

Therefore, when the mana route changes, the speed drops suddenly, which is completely different from before.

Obstructed by invisible forces, closed meridians and acupuncture points must be opened.

Every time Liu Yu's mana advances a certain distance, the speed slowly decreases and becomes slower and slower.

Fortunately, he has a strong foundation and very high mana intensity. Even if he encounters many obstacles, his mana advancement speed is very impressive.

If it were an ordinary True Lord, I'm afraid that it wouldn't take long before his stamina would be insufficient and it would be difficult to make any further progress.

Naturally, this attempt ended in failure.

"Rumble"

As soon as he started to rush through the pass, a huge sound came from Liu Yu's body, like the sound of lightning and thunder, or the roar of dragons and tigers.

But his eyes were closed tightly and his expression was always calm. If a bystander, he calmly grasps every detail.

"The intensity of my magic power is not inferior to that of the True Monarch and Demon King in the mid-term."

"Even if you don't take the "Huazhen Pill", you are still 40 to 50% sure of a breakthrough."

Liu Yu thought silently as his spiritual consciousness looked inside the body.

As the meridians are opened one by one, a new mana circulation route gradually takes shape, and the invisible force becomes stronger and stronger, causing the mana circulation speed to further decrease.

When one-fifth of the meridians and acupuncture points are opened, the invisible obstructive force has doubled compared to the initial level.

It is foreseeable that if this continues, this resistance will become greater and greater.

Whether he can finally break through the bottleneck, based on Liu Yu's current accumulation, the probability of success and failure is about between 50 and 50.

"With my own accumulation, the chance of success is about 50%."

"However, of course we cannot leave our hopes to illusory luck."

"Including Huazhen Dan and other methods, the chance of success should be close to 89%."

While rushing through the pass, Liu Yu had thoughts flashing through his mind and calmly judged the situation.

It is obvious that the speed of mana operation is getting slower and slower.

He raised his hand to cast a spell, opened the ink-colored jade bottle in front of him, and took out a silver "Huanzhen Pill" from it.

Liu Yu opened his mouth, and a bright silver elixir the size of a dragon's eye flew straight into his mouth.

"Gulu~"

The Adam's apple twitched, and the Huazhen Pill was swallowed into his belly. Under the refining of the majestic magic power, it quickly took effect.

Not only does it increase the speed of magic power, it also has an immediate improvement, doubling compared to the original speed.

Even the invisible force that hindered the operation of the technique was quickly reduced by less than half.

Immediately, Liu Yu opened up the meridians and acupuncture points and established a new great circulation, which greatly improved the efficiency in an instant.

The difficulty of breaking through the bottleneck has suddenly dropped a lot.

"It is indeed the famous "Huanzhen Pill", and its effects are extraordinary."

This thought flashed across Liu Yu's mind, and he immediately calmed down and tried his best to break through while the iron was hot.

"Boom~"

As time went by, the sound coming from his body became louder and louder.

It indicates that this breakthrough has reached a critical moment!

As time passed, a full month later, the sound like lightning and thunder gradually became lower.

Taking a Huanzhen Pill, Liu Yu spent a month building a new cycle in his body.

But at this time, he was still very solemn in his heart.

After the monks condensed the Nascent Soul, their cultivation method has changed a lot compared to the previous state. It is divided into two parts: "physical body cycle" and "Nascent Soul cycle".

The physical body cycle is completed, and then it is naturally the turn of the "Nascent Soul Cycle".

The Nascent Soul is the foundation of the true king and demon king, and is more important than the physical body.

It is undoubtedly more dangerous when crossing the barrier.

Although breakthroughs in small realms generally do not lead to death due to failure, poor control may still cause serious consequences.

For example, leaving a wound on the Nascent Soul that is difficult to heal will result in the person being unable to make further progress throughout his life.

Therefore, you must be extra careful!

"The true elixir is still half powerful, so I successfully passed the level in one go!"

The physical cycle was completed, and Liu Yu's thoughts flashed without any hesitation.

Immediately, he controlled more pure magic power and headed towards the nine-inch Nascent Soul.

In the vast dantian, wisps of cyan light continuously emerged from all over the dantian and floated towards Nascent Soul suspended above the sea of ​​mana.

Under the observation of spiritual consciousness, this scene is extremely spectacular, like a wonder between heaven and earth.

These wisps of cyan light are composed of solid mana that is countless times smaller than dust.

And based on the original mana, and after going through the new Great Weekly Cycle, both the purity and the mana intensity have been greatly improved.

"Buzz~!"

The transformed mana is continuously injected into it, making the cyan Nascent Soul shine brightly.

The aura is bright, illuminating every inch of Dantian!

With the injection of mana, "spiritual energy veins" that are difficult to observe with the naked eye continue to disappear and form in Yuanying's body.

"boom!!!"

At the same time, in the outside world, Liu Yu's spiritual pressure, which had originally reached its peak, also began to slowly rise.

Climb to higher peaks and reach new peaks!

Under his calm control, the "spiritual energy veins" of the tenth level of Qingyang Gong in the nine-inch Nascent Soul body were constantly covered by new veins.

The old context disappears, and the new context slowly emerges.

In addition to the "reviving elixir", Liu Yu naturally also prepared other means.
To be continued...
