Aotian woke up and found that it was already the next morning.

After a night's rest, his mental state and the blood qi in his body returned to the most vigorous state.

"Whew—sleep so soundly!" stood up from the ground, Aotian stretched slightly, and then took out some dry food from the storage ring, and wiped out all the dry food with the sweet spring water of the waterfall.

For the next period of time, he would have to retreat to refine the Xuan Qi and no longer be able to eat, so before the retreat, he tried to let himself eat as much as possible, so that he could last for a while longer.

However, for cultivators, with the support of Xuan Qi in their bodies, they will not starve to death if they don't eat or drink for more than ten days.

After eating the dry food, Aotian walked inward along the tunnel for another distance, and then found a suitable place to sit cross-legged and prepare to begin the retreat to refine the Xuan Qi.

There are two major steps in refining Xuan Qi.

Step 1: Transform the dantian and meridians, through a special magical secret method, to transform the meridians and dantian, but this transformation process requires the assistance of three materials: ethereal stone, ambergris liquid, and magic vine fruit, and only the transformed dantian and meridians can withstand the energy of Xuanqi.

But whether this transformation can succeed or not depends entirely on whether this person has the physique to refine Xuan Qi.

Step 2: Refining Xuan Qi also relies on a special magical secret method to absorb Xuan Qi energy into the body, and then refine it into its own energy and integrate it into the qi source in the dantian.

After the Xuan Qi and the Qi source are perfectly integrated, the Xuan Qi will completely become a part of its own energy, and it can be driven by itself at will.

Aotian took out the Ethereal Spirit Stone, the Demon Vine Fruit, and the Ambergris Liquid from the storage ring and placed them in front of him.

Then he took out the "Xuanqi Catalogue" and carefully studied the secret method of transforming the dantian and meridians several times.

This secret method of supernatural powers, like other supernatural powers, also needs to be sealed to complete, but the seal recipe is relatively simple, and he has experience in cultivating the killing seal, and Aotian quickly learned this secret method of supernatural powers.

To know the Dao, the most difficult part of cultivating supernatural powers is the first time, because it requires the cultivator to spend a lot of time studying the mystery of the seal.

And once you learn one supernatural ability, it will be much easier to learn other supernatural powers in the future. Although the seal required for each supernatural power is different, the secret of sealing is the same.

Putting down the "Xuanqi Catalogue" again, Aotian followed the method described in it, first eating the magic vine fruit, and then drinking the ambergris liquid in one gulp.

Although these two things tasted very bad, in order to obtain the powerful power of Xuan Qi, Aotian still endured it.

Feeling the magic vine fruit and ambergris liquid in his abdomen turned into a strange energy, and began to move around, Aotian immediately picked up the ethereal spirit stone and took it in his mouth.

Then the hands continued to seal, and the last two hands were combined into a strange mudra, which was parked in front of him.

In the next second, a faint golden light appeared on the surface of Aotian's body, and streams of strange energy continued to condense from the surrounding void and converge towards the surroundings of his body.

Closing his eyes slightly, Aotian felt that the ethereal stone in his mouth was like an ice cube, slowly melting, and finally turned into a stream of energy flowing into his abdomen, fusing with the energy made of the magic vine fruit and ambergris liquefied.

After the energy of the three materials fused, the seal of Aotian's hands suddenly changed.

Suddenly, the energy after the fusion of the three materials actually flowed into the meridians of Aotian under the urging of a strange force.

At the same time, the golden light on his body began to flicker slightly, and the strange energy that continued to gather from the surrounding void also began to burrow into his body and merge into his meridians.

And as those strange energies merged into the meridians, Aotian suddenly felt a burning pain sweep through his body, making him frown, and his entire cheek was twisted in pain.

But not long after, as the energy of those three materials continued to circulate in the meridians of the whole body, the burning sensation eased slightly.

In this way, the meridians of Aotian's whole body and the dantian in his body slowly underwent a transformation under the transformation of the strange energy that constantly drilled into the surface of the body.

The light in the cavern gradually dimmed, until it was completely darkened at the end, except for the flickering golden light on the surface of the Proud Celestial Body, illuminating a small area around it.

In the afternoon of the next day, the original flickering golden light on the surface of the Autean body slowly dissipated, and the hands that had been holding the seal were lowered again.

Looking at the earth-shaking changes that had taken place in the meridians and dantian in his body, Aotian felt a burst of joy in his heart.

Obviously, the transformation of the meridians and dantian was a success.

"Whew—it's time to start the second step!" opened his eyes again, and Aotian breathed a long sigh of relief in his mouth and whispered to himself.

Immediately, he picked up the "Xuanqi Catalogue" again and began to study the secret method of refining the Xuanqi in the second step.

Although this magical secret method was much more difficult than the first step, it took Aotian a few hours to learn it.

Putting down the "Xuan Qi Catalogue" again, Aotian's heart moved, and the storage ring immediately released the true yang and thunder qi in it.

The True Yang Xuanlei Qi is a low-grade Xuanqi, so as long as you don't reach out to touch it or attack it, you won't be attacked by its energy.

The scorching gaze looked at the silver light cluster, and Aotian immediately sank down, and his hands began to seal.

With the change of the seal of Aotian's hands, golden runes actually flew out of his hands, gathering around the True Yang Xuanlei Qi, and completely enveloping it at the end.

After a moment, Aotianjie's hands suddenly stopped, and then each of them formed a seal and placed it on his knees.

At the same time, I saw that a golden light appeared on the surface of Aotian's body again, and the golden rune that was wrapped in the Qi of True Yang Xuanlei was also full of golden light, and the last two strands of golden light were connected to each other.

In the next second, I saw that the golden rune wrapped in the True Yang Xuanlei Qi began to spin, and suddenly a strange force extracted the energy of the True Yang Xuanlei Qi in it, and then flowed to Aotian's body little by little, and finally entered his meridians.

And as the energy of the True Yang Xuanlei Qi flowed into the meridians, Aotian suddenly felt a tingling feeling in his body, which was caused by the thunder and lightning energy of the True Yang Xuanlei Qi.

However, when he successfully fused the energy of the first True Yang Xuanlei Qi into the qi source, his body seemed to automatically adapt to this thunder and lightning energy, and there was no longer any feeling of numbness.

In this way, the energy of the True Yang Xuanlei Qi continued to flow into Aotian's body, and it was finally refined by him and integrated into the Qi source of the dantian, which also caused the Qi source to transform at an astonishing speed.

As time passed, the energy mass of the True Yang Xuanlei Qi became smaller and smaller, but the True Yang Xuanlei Qi in Aotian's body became more and more.

It wasn't until the morning ten days later that the True Yang Xuanlei Qi wrapped in golden runes completely disappeared, and its last trace of energy was also integrated into Aotian's body, and the most refined by him was integrated into the qi source.

At this point, the refining is over.

The True Yang Xuanlei Qi that contained the powerful thunder and lightning energy completely became a part of the energy in Aotian's body.

With his hands slowly stretched out, Aotian opened his eyes again, and at the same time, the golden light and runes that were originally wrapped in the True Yang Xuanlei Qi, as well as the golden light on his body, all dissipated.

"It worked—"

Feeling the majestic True Yang Xuanlei energy in his body, Aotian couldn't help but cheer, and immediately jumped up from the ground, excited and didn't know what to do.

After a long time, Aotian once again calmed down his excitement and joy, and began to look inward to check the Xuan Qi energy in his body and the qi source after transformation.

"I've actually reached the top rank of a martial artist!" Aotian was pleasantly surprised to find that after refining the True Yang Xuanlei Qi, the qi source also transformed, and he actually jumped from the lower rank to the upper level.

"Ha Luha, Xuan Qi is really a good thing!" Aotian was ecstatic in his heart.

Immediately, he couldn't wait to start trying to drive the energy of this True Yang Xuanlei Qi.

The right hand was raised slightly, and the silver light bloomed on his palm, and the last one completely wrapped his palm.

In the next second, Aotian waved his right hand forward, and the silver light turned into a bolt of lightning, instantly bombarding the ground in front of him.

"Boom-" There was a loud bang, and the rubble flew, and a charred pit suddenly appeared on the ground.

"It's so strong!" Aotian's eyes widened in surprise, just that blow just now, if it was bombarded on a lower-level martial artist, it would definitely kill it in an instant, even a high-level martial artist, I am afraid that he would also be seriously injured.

However, Aotian also knew that the power of this True Yang Xuanlei Qi was actually far more than that.

It's just that due to the limited strength of his current meridians, it is impossible to output too much Xuan Qi energy at once. Otherwise, if you ignore the consequences of the collapse of the meridians and wantonly release the Xuan Qi energy, I am afraid that the Xuan Qi energy can directly kill the great martial artist, or even the martial spirit powerhouse.

Not only that, but this thunder and lightning energy also has a certain paralyzing effect, so after bombarding a person, even if it is not killed, it will also leave it in a short-term paralyzing state. If the two sides are in the midst of a fierce fight, a short period of paralysis is equivalent to a loss of combat effectiveness, and the result can be imagined.

"I'm already a high-level martial artist now, and the Ninefold Neigang should be able to perform the Sevenfold, plus this Xuanqi energy, even if I encounter the Dragon Horn Python again, I will have the power to protect myself. Aotian calculated his current combat strength in his heart.

Recalling that ten days ago, he was still a weak person who was chased by the dragon horn python and fled in embarrassment, but now he has the strength to compete with the dragon horn python, Aotian can't help but feel a lot of emotion in his heart: "Force, strong strength is good, I Aotian also needs more powerful strength!"

Thinking of this, Aotian clenched his fists and looked ahead, his eyes full of fine light.
