Starting with the Immortal Cultivation System, what can you use to fight me?

Lin Han looked at the female ghost charging towards him, a flicker of disdain in his eyes. Without moving, he simply waved his hand, and an invisible force swept out, knocking the female ghost flying. She slammed heavily against the wall, letting out a scream.

"Hmph, you overestimate your abilities!" Lin Han snorted coldly and turned his gaze to Li Rufeng again.

Li Rufeng's face darkened upon seeing this, a flicker of surprise in his eyes. He hadn't expected Lin Han to be so powerful that even his own female ghost couldn't withstand his attack. However, he wasn't frightened by this, but instead became even more excited.

"It seems that there is a reason why my brother lost to you." Li Rufeng smiled grimly, and began to form seals quickly with his hands. Waves of black energy began to gather around him.

Seeing this, Lin Han just smiled faintly and didn't take Li Rufeng's actions seriously. He knew very well that no matter what means the other party used, it would be futile.

"Lin Han, since you are here today, don't even think about leaving alive!" Li Rufeng roared, and the speed of his hands forming seals became faster and faster. The black energy became more and more dense, and the entire abandoned warehouse was shrouded in a gloomy and terrifying atmosphere.

However, facing Li Rufeng's roar and threats, Lin Han seemed unusually calm. He smiled slightly, with a hint of playfulness in his eyes, as if he was watching a joke about to be staged.

"Lin boy, prepare to die! - Ghost Claw of the Netherworld!" Li Rufeng roared and pushed his hands forward. A huge black claw shadow shot out from his palm, and with a sharp sound of breaking through the air, it grabbed Lin Han fiercely.

Lin Han stood there, his gaze as calm as water. Facing the surging Netherworld Ghost Claw, he didn't even blink. Just as the ghost claw was about to touch his body, he gently moved his fingers. A golden light burst out from his fingertips, instantly transforming into a golden sword light, facing the black claw shadow.

With a resounding "bang!", the golden sword light and the black claw shadow collided fiercely in the air, erupting in a dazzling light and a powerful energy wave. The surrounding space seemed to be distorted by this energy wave. A powerful gust of air spread out from the two people, blowing all nearby objects to pieces.

Li Rufeng's eyes flashed with shock upon seeing this. He hadn't expected Lin Han to be so powerful that even his Netherworld Ghost Claw couldn't hurt him at all. However, he wasn't discouraged by this; instead, he became even more excited.

"Hahaha, good! Good! Good!" Li Rufeng laughed wildly and formed seals with his hands again. This time, the black energy condensed around him was even more dense, and the entire abandoned warehouse seemed to be shrouded in a terrifying aura.

"Lin Han, today I will let you see my true strength! - The Netherworld!" Li Rufeng shouted and waved his hands violently. A stream of black energy gushed out from his palms and instantly turned into a huge black vortex, enveloping Lin Han.

Li Rufeng's figure gradually faded into obscurity within the black vortex, only his cold eyes still gleaming with a cruel light. He stared coldly at Lin Han, his voice hoarse and icy, "Lin Han, in this netherworld, your strength will be greatly weakened, while I can unleash 120% of my full potential. Today, you are doomed to die!"

However, facing Li Rufeng's arrogance and arrogance, Lin Han simply smiled faintly. He stood in the black vortex, his body motionless, his eyes slightly closed. The next moment, he suddenly opened his eyes, a sharp light flashed in them, and he shouted softly: "Break!"

With this soft shout, a golden light burst forth from Lin Han's body, instantly breaking through the black vortex's restraints and shooting towards Li Rufeng. Li Rufeng's face changed drastically upon seeing this, and he hurriedly mobilized his black energy to resist. However, the golden light was unstoppable, directly shattering his black energy and then striking him fiercely.

With a dull "puff!", Li Rufeng was struck by the golden light and sent flying backward, slamming heavily into the wall. He struggled to his feet, blood oozing from the corner of his mouth. He stared at Lin Han in disbelief, his eyes filled with shock and fear.

"You...how can you be so strong..." Li Rufeng said in a trembling voice.

"Haha, I was just playing with you just now. I only used 10% of my strength, and look at what happened to you." Lin Han chuckled and shook his head, as if mocking Li Rufeng's overestimation of his own abilities.

"You..." Li Rufeng's face flushed red with anger at Lin Han's words. He glared at Lin Han with gritted teeth, his eyes flashing with crazy anger. However, he also knew that he was no match for Lin Han.

"Li Rufeng, you are just like your brother. You both think highly of yourself, but you don't know that there are always people better than you." Lin Han said coldly, his tone full of disdain and contempt.

"Lin! Even though I've lost today, we still have a long way to go... Next time, I'll definitely take your head!" Li Rufeng said, turning around and trying to escape. He knew that if he continued to fight Lin Han, he would only die.

However, the moment he turned around, a strong suction suddenly came from behind, firmly fixing him in place. He turned around in horror, only to see Lin Han standing behind him, one hand gently pressing on his shoulder.

"There's still a long way to go?" Lin Han repeated coldly, a hint of sarcasm on his lips. "Do you think you still have a chance?"

Li Rufeng struggled to break free, but found that the suction seemed to suck him into a bottomless abyss. No matter how he struggled, it was useless.

He looked at Lin Han in horror, his eyes filled with despair and pleading: "Lin Han, spare my life, I swear I will never be your enemy again!"

"Swear? Haha..." Lin Han heard this, and a playful arc appeared on the corner of his mouth. He said, "It seems that you are undoubtedly a scumbag. Sorry, I hate scumbags the most, so your oath has no effect on me!"

"Don't worry... I won't kill you." Lin Han said lightly, but it made Li Rufeng even more frightened.

"No... don't kill me? What... what are you going to do?" Li Rufeng's voice trembled, and an ominous premonition surged in his heart.

"Of course I'll send you in to sing Tears Behind Bars with your brother, and..." At this point, Lin Han curled up the corners of his mouth in a sneer, and a golden light burst out from his fingertips and sank into Li Rufeng's brow.

"You...what did you do to me!" Li Rufeng shouted in horror, and then he felt excruciating pain all over his body as if he was being bitten by thousands of insects and ants. He couldn't help but roll on the ground, trying to relieve the pain.
