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

Lin Han smiled faintly, not rushing to attack, but closing his eyes once again to concentrate. This time, he seemed to merge with the heaven and earth, spiritual energy surging around him, as if even the surrounding air was being used by him.

Nangong Wanyue and Gu Xuanfeng watched this scene nervously, feeling both amazed at Lin Han's strength and worried about whether he could successfully pass this final test.

Tian Yunzi looked relaxed, as if he had absolute confidence in Lin Han, with a mysterious smile on his lips.

"Sky Sword Technique - The third move, sword breaks the sky!" Lin Han suddenly opened his eyes, and there seemed to be stars flowing in his eyes. An unprecedented powerful aura burst out from his body, and the whole grassland seemed to tremble.

He suddenly jumped up and rushed towards the Phantom Sound Beast King like an arrow.

"Oh, I forgot to tell you that I am actually in the Hedao stage, not the Huashen stage!" Lin Han's voice resounded like thunder during the sprint. At this moment, the aura around him suddenly rose, and the original Huashen stage fluctuations were instantly replaced by a more vast force. That was the true pressure of the Hedao stage!

The Phantom Sound Beast King's expression suddenly changed. He had never expected that this seemingly young cultivator actually had such profound cultivation hidden.

"The sword breaks the sky, once the sword is out, the sky can be broken!" Lin Han shouted softly, and the Sword of Desolation in his hand burst out with unprecedented brilliant light. Wherever the tip of the sword pointed, the space seemed to be torn apart, forming a long and thin space crack, pointing directly at the Phantom Sound Beast King.

The Phantom Sound Beast King roared in anger, knowing that if it took the blow head-on, it would undoubtedly be seriously injured. However, as the king of spirit beasts, how could it easily admit defeat? It mobilized all its spiritual power, transforming into a multicolored tornado, attempting to use the power of the storm to neutralize Lin Han's fatal sword.

"Boom!" The sky and the earth changed color, the storm and the sword light collided violently in the air, bursting out with dazzling light, illuminating the entire grassland like daylight.

The storm gradually dissipated, and the sword light slowly dissipated, revealing the figures of Lin Han and the Phantom Sound Beast King confronting each other.

There were a few shallow sword marks on the colorful scales of the Phantom Sound Beast King. Although they were not fatal, they were enough to prove the power of Lin Han's sword.

It panted, with a look of both unwillingness and admiration in its eyes.

"You win, human boy." The Phantom Sound Beast King finally admitted defeat, his voice full of fatigue and relief. "You are not only powerful, but also possess extraordinary wisdom and courage. I, the Phantom Sound Beast King, accept defeat. You have passed my test, and I will fulfill my promise and grant you the treasure!"

With that, the Phantom Sound Beast King shifted slightly, and a spatial portal slowly opened behind him. Within the portal, a dazzling light shone, faintly revealing countless rare treasures emitting an alluring luster. He extended his front paw and gently waved it, sending streams of light flying out of the portal, landing in front of Lin Han, Tianyunzi, Nangong Wanyue, and Gu Xuanfeng.

"Wow! You little bastard, you've made a killing this time!" Tian Yunzi took the treasure, his eyes instantly widening. It was a jade pendant shimmering with ancient patterns, emitting a faint spiritual energy fluctuation. It was obviously not an ordinary object. He couldn't help but burst out laughing, patting Lin Han on the shoulder, his praise overflowing with words.

(ー_ー)!!,

Lin Han was speechless for a moment: "This old drunkard... is such an easy guy to deal with. Just these scraps of copper and iron can make him so happy. No one else can do that!"

"Human boy, what's wrong? Are you not satisfied with my treasure?" Seeing that Lin Han had not yet taken the treasure, the Phantom Sound Beast King asked curiously.

"Indeed, I don't like it." Lin Han glanced at the treasure in front of him indifferently, shook his head slightly, and said with some disappointment.

"You are truly an extraordinary boy." Upon hearing this, the Phantom Sound Beast King, instead of getting angry, had a glint of admiration in his eyes. "Well, in that case, I just happened to have a special treasure in my collection. As long as you can unlock its seal, it will be yours!"

With that, the Phantom Sound Beast King moved again, slowly retrieving an ancient jade box from the depths of the spatial portal. The jade box's surface was engraved with intricate runes, glowing faintly, as if it contained endless mysteries and power. It gently placed the jade box in front of Lin Han, its eyes revealing a glint of expectation and testing.

"This jade box is what I obtained after traveling through various worlds for thousands of years. The object sealed inside is so secretive that even I cannot fully grasp its secret. If you can break its seal, it will be your destiny and my final recognition of you." There was a hint of solemnity in the voice of the Phantom Sound Beast King.

Lin Han stared at the jade box, feeling an inexplicable urge and curiosity well up in his heart. He knew that a treasure so treasured by the Phantom Sound Beast King must be something extraordinary.

So, he slowly stretched out his hand and lightly touched the surface of the jade box with his fingertips. A gentle yet powerful spiritual power wave instantly surged into his body, resonating with his own spiritual power.

"What an exquisite seal..." Lin Han thought to himself, then closed his eyes and concentrated, mobilizing all the spiritual power in his body, trying to communicate with the runes on the jade box, looking for clues to unlock the seal.

As time passed, the wind on the grassland seemed to have stopped, leaving only the subtle fluctuations of spiritual power between Lin Han and the jade box, interweaving and colliding in silence.

Nangong Wanyue, Gu Xuanfeng, and Tian Yunzi all waited with bated breath. Although they didn't know what was hidden in the jade box, they could guess from the attitude of the Phantom Sound Beast King that it was no ordinary item. Tian Yunzi's eyes widened, and he almost forgot to hold the wine gourd firmly, afraid of missing any details.

As Lin Han continued to infuse his spiritual energy, the runes on the jade box began to slowly illuminate. The light grew fainter, then darker, eventually transforming into beams of light that shot straight up into the sky, illuminating the entire sky with a dazzling array of colors. An ancient and mysterious aura permeated the air, as if some dormant power were being awakened.

"Kacha!" Finally, under everyone's nervous gaze, Lin Han successfully unlocked the seal of the jade box. The lid flicked open, and a dazzling light shone out, instantly illuminating everyone's faces. When the light gradually dissipated, everyone could see clearly that inside the jade box, a jade slip lay quietly.

This jade slip was warm and smooth, with a light and elegant hue. It was engraved with complex, indistinguishable runes, each one seemingly imbued with the ultimate truth of heaven and earth, inviting deep thought. Lin Han reached out and gently picked it up, feeling a gentle yet vast torrent of information instantly flood into his mind. It was about the inheritance of an ancient cultivation method, its profoundness far exceeding any technique he had currently known.

"This is..." Lin Han was so shocked that he could hardly control himself.
