Just a soft “chi” sound was heard.

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

The tip of the chain flashed, transforming from solid to ethereal, and pierced through the True Essence Membrane, sinking into a spot on its leg.

The Poison Dragon's right leg suddenly stiffened, then was pulled off course by the Divine Sense Chain, brushing past Han Li's body.

Then, with a deafening "boom," the Poison Dragon crashed to the ground with a tremendous roar.

Han Li swayed, retreating another dozen yards, a strange light flashing in his eyes.

Witnessing this series of sudden changes, everyone present was stunned, and the arena fell silent.

“What’s going on?” Tu Gang exclaimed in disbelief, his eyes wide.

Sun Binghe’s cold face also revealed a look of astonishment.

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

Chen Lin, standing behind Gu Qianxun, watched the scene unfold. He suddenly recalled Gu Qianxun’s earlier words. His eyes flickered, and he seemed to have realized something.

Only Gu Qianxun smiled slightly, nodding her head, as if she had anticipated this situation.

On the arena, the Poison Dragon, unharmed, slammed a palm against the ground. With a thunderous boom, he used the momentum to leap back to his feet.

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

Boom!

A large crater exploded beneath the Poison Dragon’s feet. His figure vanished again, appearing next to Han Li in an instant. His right leg, like a massive cleaver, carried afterimages, moving much faster than before, hacking fiercely at Han Li’s waist.

Where the leg passed, the void emitted an ear-splitting screech.

Han Li’s eyes narrowed. He flickered to the side, dodging, while the Divine Sense Chain shot from his palm, wrapping around the Poison Dragon's right leg with lightning speed. The tip of the chain pierced the same spot on the Poison Dragon's right leg once more.

That place was precisely where a Mysterious Aperture was located.

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

The Poison Dragon’s right leg stalled again, and he swayed before falling to the ground once more.

A smile touched Han Li's lips. With a flick of his arm, the Divine Sense Chain vanished instantly, disappearing from sight.

Surprised voices began to echo from the nearby stands, the faces of the spectators filled with disbelief.

The Poison Dragon, who had held the advantage in strength and had been on top just moments before, suddenly found the situation drastically reversed.

Han Li’s series of movements had been as swift as lightning, and the Divine Sense Chain was translucent. Apart from a few people, most of the spectators hadn't seen what had happened clearly. They had only seen Han Li wave his hand, a blurry white shadow flash past, and the Poison Dragon fall again.

Outside the exchange hall.

“Did you see this coming all along?” Tu Gang’s face darkened slightly as he turned to look at Gu Qianxun, asking.

“What do you think?” Gu Qianxun said with a soft laugh.

“Fellow Daoist Gu has remarkable insight. I, Tu, am no match for you and admit defeat. I will have the Black-Patterned Scale Turtle shell delivered there. Farewell.” Tu Gang snorted coldly, looking as if he had been taken for a ride, and turned to leave.

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

“Why are they all leaving? Li Feiyu may seem to have the upper hand, but 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 was decided long ago,” Gu Qianxun said faintly.

The purple-robed woman was stunned by this.

“Yao Li, although your strength has improved significantly in recent years, your insight is still lacking. In the future, if you have the opportunity, learn more from that Li Feiyu. It will be greatly beneficial to you. Don't do anything childish again," Gu Qianxun said, turning to walk 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 two figures quickly disappeared into the hall. Yao Li turned to look at the arena below, cold light flashing in her eyes.

A figure stood in the distance. It was Scarface.

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

Then, Scarface stomped his foot and quickly walked into the hall as well.

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

“Fellow Daoist Poison Dragon, do you still want to continue fighting?” Han Li grinned, transmitting his voice.

“How did you find out?” The Poison Dragon asked coldly via voice transmission, his shock and anger slightly reduced, seeing that Han Li was communicating privately and not speaking aloud.

“I naturally have my methods. The hidden problem with that Mysterious Aperture on your leg is quite significant. With just a little external stimulation, it can disrupt the qi and blood throughout your body. With your strength, this may not be able to injure you fundamentally, but if we exchange a few more rounds, people with keen eyes will probably be able to guess your condition.” Han Li transmitted his voice with a faint smile.

The Poison Dragon’s face turned ashen upon hearing this.

The body refinement technique he cultivated focused on tempering his right leg. It was an extremely powerful technique, but it was somewhat incomplete. He had also been too eager for quick results in his early years, injuring a Mysterious Aperture on his leg, leaving a significant hidden problem.

Later, he sought solutions from various sources, striving to make amends. Although he achieved some minor success, and it was extremely difficult to discern any abnormalities in the Mysterious Aperture from the outside, he could not fully restore it.

He had always carefully protected this weakness. Moreover, he was renowned, and he could seize the initiative in battle, so very few people could touch his body. Therefore, this secret had never been discovered all these years, but he never expected that Han Li would see through it at a glance.

Not only that, but the two attacks Han Li had just made on his hidden problem might not have been noticed by ordinary people, but Gu Qianxun, Tu Gang, and Sun Binghe must have noticed.

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

At this thought, the Poison Dragon’s mind was in turmoil.

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

His ability to discover the Poison Dragon’s hidden Mysterious Aperture was extremely fortunate. This hidden Mysterious Aperture was the same as one on the *Feather Ascension Art*.

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

However, relying solely on this non-fatal weakness to truly defeat the other party would not be easy. If the other party disregarded the fear of being seen through and used his full strength, he might not be a match.

“Fellow Daoist Poison Dragon, you don't need to worry so much. I know a method that can help you repair this Mysterious Aperture,” Han Li transmitted his voice, a thought flashing through his mind.

The Poison Dragon’s heart stirred upon hearing this. “Are you serious?”

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

“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 from the *Feather Ascension Art*, coupled with the assistance of his powerful Divine Sense, he had a 70% chance of repairing the Poison Dragon's Mysterious Aperture.

“If you can help me solve this problem, we can write off our previous grudges, and you can ask for anything you want,” the Poison Dragon looked at Han Li, took a deep breath, bowed and said.

The nearby crowd was amazed by this scene, wondering what had happened.

“Fellow Daoist Poison Dragon, you don’t need to be so polite. Let’s find a place to discuss this matter,” Han Li smiled slightly.

The Poison Dragon nodded. Without saying anything else, he turned to the muscle man nearby and announced his surrender.

The muscle man was also surprised, but since the Poison Dragon had given up, he had no choice but to announce it.

Ignoring the uproar from the stands, the Poison Dragon took Han Li straight off the arena amidst the crowd's surprised gazes and soon returned to District Nine.

The two were silent as they walked to the entrance of the Poison Dragon’s room.

The Poison Dragon raised his palm and pressed it on the door. A flash of white light flickered from the gap under the door. With a rumbling sound, the stone door slowly opened.

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

“Fellow Daoist Li, please sit.” The Poison Dragon spread out his hand, making a gesture of invitation.

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

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

“Fellow Daoist Poison Dragon, the reason why you have such a hidden problem is not only because you were too eager to cultivate, but also because of the technique you cultivate,” Han Li said after a moment of thought.

“I’m afraid Fellow Daoist Li is overthinking it. The technique I cultivate may not be some profound and mysterious secret manual, but it is an orthodox classic passed down from my clan. There will definitely be no problem,” the Poison Dragon frowned and waved his hand.

“It doesn’t matter. I don’t need you to tell me all the cultivation content of the technique. You only need to tell me the details about the opening of the apertures.” Han Li said casually.

After hesitating for a moment, the Poison Dragon told Han Li everything about the opening of the apertures in the technique, without hiding any hidden details.

"As I thought. Fellow Daoist Poison Dragon, your family's *Mystic Origin Divine Travel Art* may have an aggressive and swift cultivation style, and it may open the apertures in your legs quickly, but it is inferior in terms of stabilizing the foundation. I believe you have already noticed this problem and deliberately slowed down the speed, which is why the hidden problem is only concentrated on that one point; otherwise, there would be more problems now,” Han Li nodded and said.

“Fellow Daoist Li is right. I am impressed. Please help me solve this problem. I will definitely repay you handsomely in the future,” the Poison Dragon’s expression changed slightly. He bowed respectfully to Han Li again and said.

“To save you, the price will not be small for me. This…” Han Li hesitated.

“Fellow Daoist Li, just name your conditions. If I can do it, I will never refuse,” the Poison Dragon said, his eyes narrowing slightly.
