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

"Little bastard, I discovered an ancient secret realm some time ago. It's a bit dangerous. I wonder if you dare to go with me?" At this time, Tian Yunzi suddenly changed the subject, his eyes flashing with cunning and expectation.

"Dangerous? Haha, old drunkard, I always enjoy danger. If it's not dangerous, I won't go!" Lin Han heard this, a playful smile appeared on the corner of his mouth, and his eyes flashed with a desire for unknown challenges.

"Little bastard, let's make a deal in advance. When we get the treasure, we'll split it 50-50. How about that?" Tian Yunzi stroked his beard and proposed the conditions with a smile, looking like an old fox.

Lin Han didn't say anything, but the curve of his lips deepened a little. There was a cunning light flashing in his deep eyes, as if he had seen through Tian Yunzi's little thoughts.

Seeing that Lin Han didn't respond, Tian Yunzi gritted his teeth and said, "Little bastard, 40-60, I'll take 40 and you take 60, that's all right, right? Don't push your luck, kid!"

"Okay, deal!" Lin Han raised the corner of his mouth and agreed readily, with a gleam of eagerness in his eyes.

"However, old drunkard, you have to guarantee that there are really good things in that secret realm that are worth our risk." Lin Han said jokingly, but his eyes could not hide the expectation for unknown treasures.

"Hehe, don't worry, little bastard! How can there be no treasures in a place that I, Tian Yunzi, like? Besides, even if there are no treasures, we two fathers working together, how can we be afraid of those minor mechanisms and traps?" Tian Yunzi patted his chest and made the promise, a confident smile on his face.

The two men smiled at each other, then stretched out their bodies, transformed into two streams of light, and rushed towards the legendary ancient secret realm.

As they flew at lightning speed, the surrounding scenery slowly unfolded like a scroll, from the bustling and noisy world to the vast wasteland, to the steep mountains shrouded in clouds and mist. Each scene foreshadowed the extraordinary secret realm they were about to step into.

Lin Han and Tian Yunzi walked side by side, and the air was filled with an indescribable tacit understanding and expectation.

"Old drunkard, what secrets do you think this secret realm hides? Could it be the hiding place of some ancient divine weapon?" Lin Han couldn't help but ask again, with a hint of excitement in his voice, as if he could already imagine those dazzling treasures quietly waiting for their arrival.

Tian Yunzi laughed heartily and said mysteriously, "You little bastard, you can't get what you want in a hurry. In this secret realm, anything is possible. Perhaps there's a elixir that can change fate, a divine artifact that could create the world, or perhaps, an unknown ancient legend. In short, only by seeing it with your own eyes can you know the secret."

As they spoke, they had passed through the thick clouds and mist, and suddenly the view before them opened up to an ancient and mysterious ruin. Above the ruins, towering ancient trees and entwined vines seemed to freeze in time, and every stone carried a thousand-year-old story.

"Look, that's the entrance to the secret realm!" Tian Yunzi pointed to a stone gate in front of him that was half-hidden by dense vegetation. The stone gate was carved with intricate totems. Although it had been eroded by the years, it still revealed an extraordinary aura.

The two looked at each other, and without saying anything, they walked towards the stone gate tacitly.

However, just as they were about to step through the stone gate, a series of deep, distant bell sounds suddenly emanated from the depths of the ruins, echoing through the valley like the most ancient call of nature, or the prelude to some ancient ritual. The sudden sound of the bells caused both Lin Han and Tian Yunzi to stop in their tracks, and they gazed solemnly at the stone gate that was about to open.

"Old drunkard, this bell sound... seems a little unusual." Lin Han lowered his voice, with a hint of vigilance in his tone.

Tian Yunzi frowned, stroked his beard, and said in a deep voice, "Indeed, this bell seems to conceal some power, perhaps a test we haven't anticipated. But now that we've come this far, there's no turning back. Little bastard, are you ready?"

Lin Han nodded slightly, a hint of excitement flashing in his eyes: "Old drunkard, as the saying goes, wealth and honor are sought in danger. The more a place is filled with danger and opportunity, the more it can inspire my fighting spirit."

"Little bastard, I am very pleased to see your drive." Tian Yunzi smiled slightly, with a hint of approval in his eyes.

He took a deep breath, as if to concentrate all his caution and determination in this moment, then slowly stretched out his right hand, palm upward, and gently waved it. A light blue spiritual power surged out from his palm, turning into a slender beam of light, gently touching the stone door covered with traces of time.

The stone gate slowly vibrated under the touch of spiritual power, emitting a low, long roar, as if a sleeping giant beast was about to awaken. As the vibration intensified, the totem on the stone gate seemed to be activated, flowing with a faint light, illuminating the entire entrance with a mysterious and unfathomable light.

"boom--"

With a loud bang, the stone door burst open, and an ancient and vicissitudes of life breathed in, mixed with a faint spiritual energy and unknown danger.

"Hehe... little bastard, the door is open, let's go in and see how many unknown secrets this ancient secret realm hides." Seeing this, Tian Yunzi was about to step in.

However, at this moment, a cold female voice came from the side, like ice just beginning to melt, clear and with an undeniable majesty: "Junior Brother Tianyunzi, are you two going to explore this ancient secret realm?"

Lin Han and Tian Yunzi turned at the sound, only to see a woman dressed in white and wearing a jade crown slowly approaching. Her face was pure and beautiful, her eyes as deep as autumn water, and a faint chill surrounded her, as if she had descended from the heavens.

"Ah? Senior Sister Wanyue?" Tian Yunzi's old face instantly turned red when he saw the person coming. He stammered, "You...why are you here?"

Senior Sister Wanyue smiled slightly, a smile that held a hint of elusive meaning. She gently parted her red lips, "I sensed the fluctuations of the secret realm and knew someone was attempting to explore it. I never expected it to be you. Junior Brother Tianyunzi, it's been years since we last met. I see your cultivation has improved considerably."

Tian Yunzi scratched his head awkwardly and coughed dryly, "Senior Sister Wanyue, you're joking. My humble cultivation level is no match for yours. On the other hand, you're still as elegant as ever, and your cultivation is even more unfathomable."

"This is..." Then, Nangong Wanyue turned her gaze to Lin Han, who was dressed in snow-white clothes.

"Junior, Lin Feiyu greets Master Wanyue!" Upon seeing this, Lin Han hurriedly bowed and saluted, his words showing humility and respect.

"Lin Feiyu? What do you mean by calling me Master?" Nangong Wanyue was stunned at first, then her eyes moved between Lin Han and Tian Yunzi. She seemed to understand something, and a faint smile appeared on the corner of her mouth. "Oh... I see. You are the disciple of Junior Brother Tian Yunzi, right?"

"That's right, Senior Sister Wanyue, this brat is my disciple!" Tian Yunzi interrupted from the side, with a bit of smugness and pride on his face.
