"Deal!"

Han Li heard this and immediately agreed without the slightest hesitation.

"Hehe, Fellow Daoist Li, take your time. I have a small request. I hope that while imparting the technique, you can also include some cultivation insights. How about that?" Gu Qianxun asked with a faint smile.

"That's not impossible, but whether it's this Feather Ascension Technique or my cultivation insights, Fellow Daoist can only cultivate them yourself and not pass them on to others. If Fellow Daoist Gu agrees, swear an oath. If you can't, then this matter is off." Han Li nodded and said through voice transmission.

"Such a technique is probably unique in the entire Green Goat City. Even if you didn't say so, I wouldn't pass it on to others." Gu Qianxun agreed directly upon hearing this.

Having said that, she immediately made a solemn oath in her sea of consciousness.

Seeing this, Han Li immediately communicated with her through divine sense, exchanged cultivation techniques, and obtained the Tier Earth beast core.

This transaction was thus completed, and it could be considered a win-win situation.

In the following time, Han Li searched the exchange fair for another half a day. After having no other gains, he bid farewell to Poison Dragon and left first.

Han Li left the trading area but did not return to his residence. Instead, he came to the exchange hall.

"Fellow Daoist Li, what do you want to exchange this time?" A tall, thin youth in a crimson robe said with a smile behind the rectangular stone table.

Han Li was now a celebrity in the Xuan Dou Arena, and his frequency of fighting on stage was much higher than that of ordinary Xuan Dou fighters. He came here more often than ordinary Xuan Dou fighters, and over time, he became acquainted with these people.

"I'm not exchanging items this time. I want to cultivate in the Star Pool." Han Li took out his number plate and handed it over.

The Xuan points on the number plate showed one hundred and eighteen points.

Although he had never rested in the past few years and had earned a lot of Xuan points, they were all used for cultivation, and there was not much left.

The tall, thin youth nodded upon hearing this, took the number plate, and swiped it with a silver short rod. Immediately, one hundred Xuan points were deducted, leaving only eighteen points.

"Fellow Daoist Li, please follow me." The tall, thin youth instructed the staff next to him, got up, and led Han Li to the entrance of the passage in the hall with the words "Star Pool" written on it.

The stone door at the entrance of the passage was still tightly closed. The tall, thin youth took out a blue token and placed it on the tightly closed stone door. There was a square recess on the stone door, which perfectly matched the blue token.

Strands of starlight emanated from the token, spreading quickly on the stone door.

Then, with a soft "click," the stone door slowly opened.

"Let's go." The tall, thin youth took down the token and led Han Li in. The stone door closed again.

Inside the stone door was also a dimly lit tunnel. After walking for a short while, steps leading upwards appeared in front.

The two stepped onto the stairs and went up. They walked for a long time before reaching the end.

At the end of the tunnel was a stone room with an area of ​​twenty to thirty zhang. It was not entirely accurate to call it a stone room, because there was no roof above the stone room, but it was open to the sky. It looked like it was in a valley on a mountaintop.

In the center of the valley was a round pool of more than ten zhang in size, and around the round pool, there were actually rows of white exotic trees, more than a dozen of them, surrounding the round pool in the center.

The trunks, branches, and leaves of these white trees all appeared in a pure white color, as if they were carved from white jade. They looked quite peculiar.

Moreover, the branches and leaves of the white exotic trees were very lush. After spreading out, they almost completely occupied the sky above the valley. The tree trunks were covered with countless white patterns, which stretched all the way into the round pool.

At this moment, night quietly fell, and trails of starlight fell from mid-air.

The leaves of these white exotic trees emitted bursts of white light, and all the nearby starlight converged and merged into the white leaves. Then, along the patterns on the trees, it converged into the round pool.

The white pool water was filled with substantive starlight, shimmering with waves, like a pool of star water.

Next to the round pool, a man in white robes sat cross-legged, closing his eyes and resting.

This person looked to be in his early thirties, with exceptionally fair skin, without a trace of blood, and his hair and eyebrows were all white.

"Sir, this Li Feiyu has paid one hundred Xuan points and wants to enter the Star Pool for cultivation once." The tall, thin youth respectfully bowed to the man in white robes and said.

The man in white robes opened his eyes, glanced at Han Li, and nodded.

The tall, thin youth bowed again and retreated.

The man in white robes glanced at Han Li again, without saying anything, took out an hourglass the size of a palm and placed it beside him. The fine sand inside flowed silently.

Seeing this, Han Li immediately jumped into the round pool. With a "poof," white water splashed in all directions, like beads.

This was not the first time he had come to the Star Pool, so he knew the rules here very well.

Paying one hundred Xuan points could exchange for one opportunity to enter the Star Pool, but the cultivation time was only one hour.

When the hourglass ran out, it would be exactly one hour, and he had to leave at that time.

He sat down cross-legged in the pool and began to circulate the Feather Ascension Technique.

Strands of pure astral power gathered and merged into his body, much stronger than when he absorbed beast cores.

Han Li circulated these astral powers, condensed them into one, and rushed towards a mysterious acupoint in his abdomen.

This was the only mysterious acupoint in the Feather Ascension Technique that was not on the legs, but it was also the most important mysterious acupoint. It was also the most difficult hurdle in the Feather Ascension Technique.

As long as he opened this place, the power of the mysterious acupoints on the left and right legs could be connected in one breath. The Feather Ascension Technique could be basically considered complete, and the remaining few mysterious acupoints were just minor details and not worth worrying about.

In the past few years, Han Li had almost desperately cultivated the Feather Ascension Technique. With various opportunities, his progress was rapid, and he had cultivated to this bottleneck three months ago.

In the past three months, he had tried various methods to break through, but unfortunately he had not succeeded. He had only opened a small part of the mysterious acupoint and could no longer make any progress.

That was why he had accumulated Xuan points for a period of time and entered the Star Pool to try to break through.

With his will urging, the vast astral power slammed into the tightly closed mysterious acupoint.

There was a "boom" in his mind, and his body trembled involuntarily. The mysterious acupoint did not respond at all, and the condensed astral power collapsed and scattered.

Han Li was not surprised by this situation. He circulated the Feather Ascension Technique again, absorbed the astral power in the Star Pool, and began the second impact.

Boom boom boom!

Strands of astral power slammed into the mysterious acupoint, wave after wave.

In the blink of an eye, most of an hour had passed.

Han Li's face was faintly red, and his forehead was slightly sweaty. Such continuous impact was also a considerable burden on his body.

However, such hard work also brought great gains. The mysterious acupoint was opened a lot again. Although it was not completely opened, it was not far away.

Han Li took a deep breath, slightly adjusted his body, and began the impact again.

However, the situation changed again. The mysterious acupoint that had been opened for most of the time became tough again. Even with the impact of the Star Pool's power, it slowly lost its effect.

"The Feather Ascension Technique is indeed not so easy to practice..." Han Li murmured to himself, not feeling too disappointed. He flipped his hand and took out a beast core the size of a fist.

This was the Tier Earth beast core that he had just obtained from Gu Qianxun. Inside the beast core was a vortex of white starlight visible to the naked eye, rolling endlessly.

Strands of terrifying astral power fluctuations emanated from the beast core, even surpassing the Star Pool.

A hint of joy appeared on his lips, and he swallowed it into his belly without hesitation.

The reason why he traded with Gu Qianxun was not only because he valued the other party's Vajra Power, but also because of this Tier Earth beast core.

The astral power contained in this item was very powerful, which was very helpful for impacting the mysterious acupoints, so he agreed to the transaction so readily. Otherwise, he would not be willing to transfer his cultivated techniques and secrets to others.

Although the higher the level of the beast core, the more difficult it was to refine, he had the Palm Heaven Bottle in hand, and refining it was a piece of cake.

The beast core quickly melted, turning into an exceptionally powerful but also extremely violent astral power, which rushed around in Han Li's body.

But then the Palm Heaven Bottle emitted a suction force, and soon re-guided these beast core astral powers back.

Han Li fully circulated the Feather Ascension Technique, manipulating this beast core astral power, coupled with the astral power in the Star Pool, to form a larger torrent, impacting the mysterious acupoint.

A loud "boom" exploded in Han Li's mind, and the power of divine sense surged.

The power of blood and qi in his body also rolled like boiling, and many mysterious places near the mysterious acupoint were impacted and opened, even shaking the dantian.

The final pass of the mysterious acupoint buzzed and vibrated, and the vibration became more and more intense, and it began to slowly open again.

Han Li was overjoyed.

He took a deep breath, circulated the technique faster, urged the power of the beast core, and at the same time, more and more of the power of the Star Pool around him merged into his body and poured towards the mysterious acupoint.

With his body as the center, a vortex appeared in the Star Pool.

Near the Star Pool, the man in white robes raised his eyebrows, opened his eyes and looked at Han Li, revealing a hint of surprise.

"What kind of mysterious acupoint is this child cultivating, that can cause such a big commotion?" The man in white robes muttered to himself.

The Star Pool did not allow the use of divine sense to randomly investigate others, so he did not investigate, but looked at Han Li, with a light of interest in his eyes.

Time passed little by little, and the hourglass beside him flowed quickly, and soon it was all gone.

Han Li was still sitting cross-legged in the Star Pool, and a bright star light emitted from his lower abdomen, flickering constantly, and the fluctuations of more and more intense astral power, anyone could see that he was at a critical moment in cultivation.

The man in white robes glanced at the hourglass that had already leaked, hesitated slightly, and did not wake Han Li.

After another half quarter of an hour, a slight "crack" sound came from Han Li's lower abdomen, and the mysterious acupoint light emitted suddenly brightened, and the mysterious acupoint finally opened suddenly.

The other mysterious acupoints on his legs also emitted bursts of star light, connected into one piece, and his whole body became as light as a feather.

Han Li suddenly opened his eyes, his eyes full of surprise. With a movement of his body, he actually flew directly from the Star Pool.

A bright starlight emanated from the mysterious acupoints on Han Li's legs, forming a cloud-like light, which held his body, making him float in the air without falling.
