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

"It's you... Leng Aotian! I never thought you'd dare to show up again. Back then, Master showed mercy to you, but you didn't repent. Instead, you became even more ruthless, killing innocent people. Today, I will enforce justice and clean up this mess!" Uncle Jiu's body shook, his eyes wide open with anger, and there was a faint fluctuation of true energy around him, obviously he was ready for battle.

"Haha... Ninth Junior Brother, is that old guy in his coffin yet? To be honest, I'm so powerful now, thanks to him for sparing my life, giving me the opportunity to learn deeper and more profound secret techniques of the evil way."

Leng Aotian laughed coldly, his eyes filled with hatred for the past and arrogance of the present.

"Get out of here, you little bastard!" He gently raised his foot and kicked Huang Xian aside. Huang Xian rolled to the ground and curled up in pain, his golden eyes filled with fear and helplessness.

"Don't worry! Master is very energetic. Even if you die, he will not die."

"Zhao! Old man, you're really lucky!" Leng Aotian spat, then added: "Ninth Junior Brother, after I kill you, I will go to Maoshan myself and kill everyone there, including all living creatures."

"Don't worry! Ninth Junior Brother, we are brothers after all. I won't let you die in pain. Instead, I will torture you slowly, hehehe..."

"Leng Aotian! Do you still remember me?" At this moment, Li Tiangang's voice suddenly rang out, his eyes becoming unusually firm, filled with the flames of revenge.

Upon hearing this, Leng Aotian's gaze finally shifted from Uncle Jiu to Li Tiangang, a playful smile playing on his lips. "Oh? Isn't this the Li Tiangang I easily defeated and escaped back then? What? Do you think you have the right to speak to me now?"

Li Tiangang clenched his fists, his knuckles white from the exertion, but his eyes shone with a light ignited by hatred and determination. "Leng Aotian, you killed my wife and children and ruined my future. Today, even if it costs me my life, I, Li Tiangang, will make you pay with blood!"

"Blood debt must be paid with blood?" Leng Aotian sneered, as if he had just heard the biggest joke in the world. "You think that with just your little bit of Taoism, you can do anything to me? I'd like to tell you that my power now is beyond your imagination."

Before he finished speaking, a black demonic energy suddenly surged around Leng Aotian. The demonic energy was thick and evil, as if it could devour all light and vitality.

He slowly raised his hand, and a dark ball of energy condensed in his palm, which suddenly blasted towards Li Tiangang.

"Be careful!" Uncle Jiu and Lin Han warned almost at the same time. Uncle Jiu flashed and stood in front of Li Tiangang. He moved the magic formula in his hands, and a golden shield suddenly appeared in front of them, blocking the black energy ball.

"Oh... Ninth Junior Brother, I didn't expect your strength to have improved. However, in front of me, it's still not enough." Leng Aotian curled his lips into a sneer, as if he didn't take Uncle Jiu's defense seriously.

Uncle Jiu's face was grim, but he didn't flinch. He knew Leng Aotian's strength was far from what it once was, but his determination to uphold justice and the honor of his sect made him fearless. "Leng Aotian, you've fallen into the devil's way and are beyond redemption. Today, I will seek justice not only for my fallen fellow disciples, but also for the innocent victims!"

"Hahaha... Ninth Junior Brother, are you still as naive as you were back then? Do you think you can conquer everything with justice and faith alone? In this world where the strong prey on the weak, strength is the only truth!" Leng Aotian laughed wildly, and the demonic energy around him became even stronger, as if it was going to swallow up the entire night sky.

"Brother Li, you've just recovered, so it's not appropriate for you to fight. Since this happened in Maoshan, I'll handle it!" Uncle Jiu turned to Li Tiangang and said, his tone filled with unquestionable determination and a hint of concern.

He knew very well that Li Tiangang had just gotten rid of the shackles of five disadvantages and three shortcomings, and his strength was not yet solid, so it was not appropriate to confront him head-on at this moment.

"Okay... Fellow Daoist Jiu, be careful!" Seeing Uncle Jiu's determined face, Li Tiangang also understood his current situation and nodded. He stepped aside, his eyes fixed on the battlefield, ready to provide support at any time.

Lin Han also reminded Uncle Jiu: "Uncle Jiu, be careful. If you can't defeat me, don't fight me. Leave it to me!"

"Hmm..." Uncle Jiu nodded, a look of determination and resoluteness flashing in his eyes.

As the night wind howled, the atmosphere on the battlefield became extremely tense.

Uncle Jiu took a deep breath, and the true energy in his body began to surge wildly. Golden light overflowed from his body, forming a sharp contrast with the surrounding darkness.

He quickly formed seals with his hands and muttered something, and every word seemed to contain the power of heaven and earth.

"The universe is boundless, the way follows nature, the true fire of Mount Mao will incinerate all evil!" Uncle Jiu shouted softly, and a tiny golden flame suddenly emerged from his fingertips. Although small, the flame contained astonishing heat and pure spiritual energy. As his gestures changed, the flame rapidly expanded, transforming into a huge fire dragon, roaring and pouncing towards Leng Aotian.

Seeing this, Leng Aotian curled up a disdainful smile at the corner of his mouth. He did not move, but just waved his sleeves lightly. A thicker black gas surged out of his body, turning into a huge black magic net, trapping the fire dragon tightly.

The flame struggled in the magic net, but could not break free. Eventually, it was swallowed up bit by bit and turned into nothing.

"Ninth Junior Brother, I've played with these little tricks before, so don't show them off to embarrass yourself. Instead, show me something more presentable so I can see how much you've grown!" Haha..." Leng Aotian's laughter echoed in the night sky, with a hint of arrogance and disdain.

"Okay! Then I'll satisfy your curiosity, brother!"

Uncle Jiu's expression hardened, he muttered something, and then shouted in a low voice, "The Secret Art of Heavenly Talisman - Wind Blade Talisman! Go!"

Before he finished speaking, a talisman appeared out of thin air in his palm, flashing with dazzling light. Then he suddenly threw it into the sky. The talisman turned into countless sharp wind blades, like sharp blades falling from the sky, cutting through the night sky and heading straight for Leng Aotian with a whistling sound.

Leng Aotian's expression changed slightly upon seeing this. He had obviously not expected Uncle Jiu to have such a trick. He quickly retreated, and at the same time, he formed seals with his hands. The black demonic energy quickly condensed into a solid shield, trying to resist the wind blades.

"Bang! Bang! Bang!"

The wind blade collided with the magic shield, making a deafening sound. Layers of air waves were stirred in the air, and the surrounding trees and rocks were shaken down by this force.

However, although Leng Aotian's magic shield was strong, it could not withstand such dense and sharp wind blade attacks, and cracks gradually appeared.

"Hmph, quite interesting!" Leng Aotian snorted coldly, a fierce look flashed in his eyes. He stomped his foot suddenly, the ground shook, and an even more powerful demonic energy burst out from his body, defeating the wind blades that were about to penetrate the magic shield one by one.
