Just then, a soft "chi" sound was heard.

A translucent, crystalline chain shot out from Han Li's palm. It was the Divine Sense Chain. It instantly wrapped around the Poison Dragon's right leg and flung it violently to the side.

A flash of light appeared at the tip of the chain, solidifying from nothingness and passing through the True Essence Membrane in a flash, disappearing into a certain spot on his leg.

The Poison Dragon's right leg froze for a moment, then was pulled off course by the Divine Sense Chain, flying past Han Li's body.

Immediately after, with a "boom," his entire body slammed into the ground, creating a loud crash.

Han Li swayed, retreating another dozen or so feet to the side, a strange light flashing in his eyes.

Witnessing this series of events, everyone present was stunned, and the scene fell silent.

"What's going on?" Tu Gang asked incredulously, his eyes wide.

Sun Binghe's cold face also showed a hint of surprise.

The purple-robed woman stared blankly, her cherry lips slightly parted, almost exclaiming in surprise.

Chen Lin, standing behind Gu Qianxun at this moment, looked at the scene on the stage. He suddenly recalled what Gu Qianxun had said earlier. His eyes flickered, and he seemed to have realized something.

Only Gu Qianxun showed a hint of a smile on her lips, nodding slightly, as if she had expected this situation.

On the arena, the Poison Dragon's body slammed into the ground, but he was not injured. He slapped the ground with his palm, and amidst a loud crash, he leaped up using the force.

He turned his head to glare at Han Li, a hint of strangeness in his eyes. He roared and his figure moved.

Boom!

A large pit exploded under the Poison Dragon's feet, and his figure disappeared again. The next moment, he appeared beside Han Li, his right leg like a giant cleaver, carrying streaks of afterimages, much faster than before, and slashing fiercely towards Han Li's waist.

Wherever the leg shadow passed, the void emitted an ear-piercing shriek.

Han Li's eyes narrowed, and his figure swayed, dodging to the side. At the same time, the Divine Sense Chain shot out from his palm, wrapping around the Poison Dragon's right leg like lightning. The tip of the chain pierced the same spot on the Poison Dragon's right leg again.

That was precisely the location of a Mysterious Aperture.

Pierced by the Divine Sense Chain, the starlight emanating from the Mysterious Aperture suddenly became violently chaotic, and the nearby True Essence Membrane also became much thinner.

The Poison Dragon's right leg faltered again, and his entire body swayed, falling to the ground once more.

A smile appeared on Han Li's lips. With a flick of his arm, the Divine Sense Chain instantly disappeared and vanished.

Surprised voices began to emerge from the nearby stands, the faces of the audience filled with disbelief.

The Poison Dragon, who had the advantage in strength and had been dominating the situation just a moment ago, suddenly saw the situation take a sharp turn for the worse.

The series of actions of Han Li and the Poison Dragon were as fast as lightning. The Divine Sense Chain was also semi-transparent. Apart from a few, most of the people nearby did not see what was happening. They only saw Han Li wave his hand, a blurry white shadow flashed, and the Poison Dragon fell again.

Outside the exchange hall.

"Did you see it all along?" Tu Gang's expression darkened slightly as he turned his head to look at Gu Qianxun and asked.

"What do you think?" Gu Qianxun said with a soft smile.

"Fellow Daoist Gu has excellent vision. I, Tu, cannot compare and admit defeat. I will have someone send the Black-Patterned Scale Tortoise shell there. Farewell." Tu Gang snorted coldly, looking as if he had been swindled, and turned to leave.

Sun Binghe's eyes flickered, and he also turned to leave.

"Why are they all leaving? Although Li Feiyu seems to have the upper hand, the Poison Dragon hasn't suffered any fatal injuries. The outcome hasn't been decided yet," the purple-robed woman said in surprise.

"The outcome has long been decided," Gu Qianxun said indifferently.

The purple-robed woman was stunned upon hearing this.

"Yao Li, although your strength has improved a lot over the years, your vision is still lacking. In the future, find more opportunities to learn from that Li Feiyu. It will be of great benefit to you. Don't make any more childish moves." Gu Qianxun said, then turned and walked into the hall.

"Yes," Yao Li replied respectfully, a hint of shame and anger flashing in her eyes, as if she had been insulted.

Chen Lin nodded slightly to Yao Li and followed behind Gu Qianxun.

The figures of the two quickly disappeared into the hall. Yao Li turned her gaze to the arena below, a cold light flashing in her eyes.

A figure stood in the distance, it was Scarface.

He looked towards the direction where Gu Qianxun had left, his face pale, his eyes filled with fear.

Immediately after, Scarface stomped his foot and quickly walked into the hall.

On the arena, the Poison Dragon immediately stood up again, looking at Han Li with a mixture of shock and anger, but did not attack again.

"Fellow Daoist Poison Dragon, do you still want to continue fighting?" Han Li grinned and said through voice transmission.

"How did you find out?" When the Poison Dragon saw that Han Li was communicating through voice transmission and did not speak aloud, the shock and anger on his face subsided slightly, and he asked coldly through voice transmission.

"I naturally have my methods. The hidden danger in that Mysterious Aperture on your leg is quite significant. Just a little external force is enough to disrupt the qi and blood throughout your body. Your strength is high. Although this won't hurt your foundation, if we exchange a few more blows, the people with discerning eyes present will probably be able to guess the situation on your body," Han Li said with a faint smile through voice transmission.

Upon hearing this, the Poison Dragon's face turned ashen.

The body refining technique he cultivated focused on tempering his right leg. It was an extremely powerful Technique, but this Technique was somewhat incomplete. He was too eager for quick success in his early years, injuring a Mysterious Aperture on his leg, leaving a considerable hidden danger.

Later, he sought various methods and tried his best to make amends. Although he had made some minor progress, and it was extremely difficult to see any abnormalities in the Mysterious Aperture from the outside, he could never fully restore it.

He had always carefully protected this weakness. Moreover, he was already well-known, and he was able to gain the upper hand when fighting with others. Very few people could touch his body, so this secret had never been discovered over the years. He did not expect that Han Li would see through it at a glance at this moment.

Not only that, but the two attacks Han Li had just made on his hidden danger might not be visible to ordinary people, but Gu Qianxun, Tu Gang, and Sun Binghe must have noticed it.

At their level of strength, even a small mistake was enough to determine life and death, let alone such a big weakness.

At the thought of this, the Poison Dragon was immediately flustered.

Han Li watched the changes in the Poison Dragon's expression, his eyes flickering slightly.

He was extremely fortunate to be able to discover the hidden Mysterious Aperture of the Poison Dragon. This hidden Mysterious Aperture was the same as one of the Mysterious Apertures on the *Yu Hua Ascension Technique*.

He had just opened this Mysterious Aperture, and he was most sensitive to the various changes in this Mysterious Aperture. In addition, his Divine Sense was extremely powerful, which allowed him to discover the Poison Dragon's weakness.

However, it would not be easy to truly defeat his opponent with just this non-fatal weakness. If the other party abandoned his concerns about being seen through by others and exerted his full strength, he might not be his opponent.

"Fellow Daoist Poison Dragon, you don't have to worry so much. I know a method that can help you repair this Mysterious Aperture," Han Li said through voice transmission after a thought.

Upon hearing this, the Poison Dragon was overjoyed, saying excitedly, "Are you telling the truth?"

In his excitement, he forgot to transmit his voice and spoke directly, his voice trembling slightly.

"I specialize in the cultivation of leg Mysterious Apertures, otherwise I wouldn't have been able to discover your problem," Han Li said.

He was not exaggerating. With the correct method of opening this Mysterious Aperture on the *Yu Hua Ascension Technique*, coupled with the assistance of his powerful Divine Sense, he was 70% confident that he could repair the Poison Dragon's Mysterious Aperture.

"If you can help me solve this problem, our previous grievances will be wiped out, and you can make any request you want," the Poison Dragon said, looking at Han Li. He suddenly took a deep breath and bowed deeply.

Everyone nearby was extremely surprised to see this scene, not knowing what had happened.

"Fellow Daoist Poison Dragon, you don't have to be so polite. Let's find a place to discuss this matter," Han Li said with a slight smile.

The Poison Dragon nodded, turned his head without saying a word, and announced to the muscular man nearby that he conceded.

The muscular man was also surprised at this time, but he had no choice but to announce it as such since the Poison Dragon had given up on his own.

Ignoring the noisy stands nearby, the Poison Dragon led Han Li off the arena under the astonished gazes of the crowd, and soon returned to District Nine.

The two arrived at the door of the Poison Dragon's room in silence along the way.

The Poison Dragon raised his palm and pressed it on the door. A burst of white light flashed slightly from the gap under the door, and the stone door slowly opened with a rumble.

Entering the room, Han Li found that the Poison Dragon's room was much larger than his and Chen Lin's, and there were even more furnishings such as stone platforms and animal skins.

"Fellow Daoist Li, please sit." The Poison Dragon spread out his palm, making a gesture of invitation.

Han Li sat down generously at the stone table, waiting for the Poison Dragon to speak.

"This hidden worry has been troubling me for many years. Fellow Daoist Li, do you really have a way to solve it?" Sure enough, the Poison Dragon couldn't help but ask as soon as he sat down.

"Fellow Daoist Poison Dragon, the reason why you buried such a hidden danger is not only because you were eager to practice, but also, according to my guess, it may also be related to the Technique you practice," Han Li said after pondering for a moment.

"This... I'm afraid Fellow Daoist Li is overthinking it. Although the Technique I practice is not a profound secret manual, it is also an orthodox classic passed down from the clan and will definitely not have any problems," the Poison Dragon said with a frown, waving his hand.

"It doesn't matter, I don't need you to tell me all the Technique practice content, you just need to tell me in detail about the content of the Technique on opening apertures," Han Li said casually.

After hesitating for a moment, the Poison Dragon still told Han Li about the opening of apertures in the Technique in detail, even without hiding some hidden subtleties.

"Sure enough. Fellow Daoist Poison Dragon, your family's *Profound Origin Divine Travel Art* Technique, although the cultivation momentum is aggressive and swift, and the speed of opening the apertures in your legs is faster, it has fallen behind in the matter of consolidating the foundation. I believe you have already noticed this problem and deliberately slowed down the speed, which is why this hidden danger is only concentrated on that one point, otherwise there would be more problems now," Han Li nodded and said.

"Fellow Daoist Li is right on the mark, I admire you. Please help me solve this trouble, I will definitely repay you handsomely in the future," the Poison Dragon said, his expression changing slightly, bowing respectfully to Han Li again.

"If I want to save you, the price for me will be equally high, this..." Han Li pretended to hesitate.

"Fellow Daoist Li, just state your conditions. If I can do it, I will never shirk my responsibility," the Poison Dragon said, his eyes slightly condensed.
