Let you be a good grandson, you raise a group of banshees?

Just when Hall was about to give up, an oasis suddenly appeared in front of him. The lush trees and clear lake water looked like a paradise on earth, forming a sharp contrast with the desolate desert around it.

"Damn! There really is an oasis!" Hall exclaimed, ran over, dived into the lake and drank it all.

Lu Yuan also walked to the lake, washed his face, then found a shady place to sit down and close his eyes to rest.

After drinking enough water, Hall walked over to sit next to Lu Yuan and asked curiously, "How did you know there is an oasis here?"

Lu Yuan opened his eyes and said calmly: "Feeling."

"Feeling?" Hall was confused. "What feeling?"

Lu Yuan didn't explain, he just smiled and said, "Take a break, and we'll move on."

Hall wanted to ask more, but seeing that Lu Yuan was unwilling to say more, he tactfully shut up.

The two rested for a while and then set out again. This time, with the nourishment of the oasis, Hall's spirits improved a lot and he no longer complained.

As they went deeper into the desert, the surrounding environment became more and more bizarre. The wind and sand became stronger and stronger, and the temperature became higher and higher, as if they were in a huge furnace.

"Is there really a secret in this damn place?" Hall couldn't help but ask.

"Of course." Lu Yuan said firmly, "Moreover, it is a secret that can change the whole world."

Hall was stunned. "Change the world? So exaggerated?"

Lu Yuan didn't say anything, but just quickened his pace.

Suddenly, a huge sand dune appeared in front of us. It had a strange shape, like a giant palm standing in the desert.

"What is that?" Hall asked, pointing at the sand dunes.

Lu Yuan stared at the sand dune with burning eyes and said in a deep voice: "If I'm not mistaken, that's where we are looking for."

The two came to the foot of the sand dune and looked up, only to see the sand dune towering into the clouds like a majestic mountain.

"How do we get up there?" Hall asked.

Lu Yuan did not answer, but flew up and flew towards the top of the sand dune. Seeing this, Hall hurriedly followed.

The two flew to the top of the sand dune and were shocked by the scene before them.

I saw a huge pit on the top of the sand dune, which was bottomless and seemed like the gate to hell.

"What is this?" Hall exclaimed.

A glimmer of excitement flashed in Lu Yuan's eyes, "This is the secret I'm looking for."

After saying that, he jumped and jumped into the pit.

"Hey! Wait for me!" Seeing this, Hall also jumped down.

The two fell into the pit, and they felt a black screen before their eyes, and then they lost consciousness...

What is in the pit? What challenges will Lu Yuan and Hall face?
The two fell into the pit, as if they had fallen into a bottomless abyss. The feeling of weightlessness from the rapid fall terrified Hall. He closed his eyes tightly, and the sound of the wind whistling in his ears was as piercing as the howling of ghosts and wolves. After an unknown amount of time, the feeling of falling suddenly disappeared, and Hall fell heavily to the ground, his bones all falling apart.

"Ouch, my old waist!" Hall groaned, struggling to get up, and found himself in a huge underground cave. The top of the cave was inlaid with crystals emitting a faint blue light, illuminating the entire cave like daylight.

Lu Yuan stood steadily aside, brushed off the dust on his body, and looked calm, as if the fall just now was just child's play to him.

"Are you okay?" Lu Yuan glanced at Hall with a hint of teasing in his tone.

"Nonsense! How can you be okay after falling from such a high place!" Hall rubbed his buttocks, looking resentful, "Tell me, what the hell is this place?"

Lu Yuan did not answer, but walked straight to the depths of the cave. Seeing this, Hall could only limp and follow. Deep in the cave, a huge altar stood in the center, engraved with strange runes, exuding an ancient and mysterious atmosphere.

"What is this?" Hall asked, pointing at the altar.

"This is what I'm looking for." Lu Yuan's eyes flashed with excitement.

Suddenly, the runes on the altar began to flicker, and a dazzling light shot up into the sky, illuminating the entire cave like daylight.

"What's going on?" Hall exclaimed.

The light faded, and a mysterious man in a black robe and a hood appeared on the altar.

"Who?" Hall asked warily.

The mysterious man slowly raised his head, revealing a pale and handsome face. His eyes were as bright as stars, yet with a hint of evil charm.

"Long time no see, Lu Yuan." The mysterious man's tone was cold, as if he came from the Nine Nether Hell.

Lu Yuan narrowed his eyes, a cold light flashed in his eyes, "It's you! You are still alive!"

"Thanks to you." The mysterious man sneered, "Back then you threw me into the abyss, but you didn't expect that I would turn a disaster into a blessing and gain even greater power."

"Who are you?" Hall was confused and had no idea what the two were talking about.

"He is my old friend and also my old enemy." Lu Yuan said calmly, "His name is Night Demon, and he is a madman who wants to destroy the world."

"Destroy the world?" Hall was shocked. "Are you kidding?"

The Night Demon laughed wildly, "That's right! I will turn this world into a hell!"

"Don't even think about it!" Lu Yuan roared, his figure flashed, and he rushed towards the Night Demon.

The Night Demon sneered, a black sword appeared in his hand, and he rushed forward.

The two men engaged in battle in an instant, with swords flashing and energy overflowing, shaking the entire cave.

Hall was stunned. He had never seen such a fierce battle.

Lu Yuan's strength is unfathomable, and each of his moves contains the power to destroy the world. Ye Mo is not to be outdone, his swordsmanship is weird and unpredictable, making it hard to defend against.

The two of them went back and forth, fighting inextricably.

Suddenly, the Night Devil roared, and a powerful dark aura emanated from his body. His body instantly swelled up and turned into a huge black monster with a hideous and terrifying face.

"What the hell is this?" Hall turned pale with fear.

"This is the true form of the Night Demon." Lu Yuan said in a deep voice, "Be careful, his power is stronger than before."

The night demon let out a deafening roar, waved its huge claws, and pounced towards Lu Yuan.

Lu Yuan dodged the Night Demon's attack with a flash, then punched the Night Demon in the chest.

boom!
With a loud bang, the Night Demon was knocked away by Lu Yuan's punch and fell heavily to the ground.

"Roar!" The Night Demon let out an angry roar and stood up again, emitting an even stronger dark aura from his body.

Lu Yuan's face was solemn. He knew that the real battle had just begun.

At this moment, a strange noise suddenly came from the top of the cave. (End of this chapter)
