Autobiography of Li Yunfei, a time traveler

Chapter 397 Mysterious Voice

The strange sound echoed in the cave, like an ancient and mysterious ballad, or like the painful groan of some creature. Li Yunfei and others looked at each other in bewilderment. The joy of defeating the giant beast was instantly dispelled by the unknown sound, and was replaced by deeper vigilance and uneasiness.

Li Yunfei frowned, the artifact in his hand emitting a faint light, "Everyone be careful, this sound may not be simple." His voice was low and serious, echoing in the cave.

Zhang Hao struggled to get up from the ground. The pain from the wound made his face pale, but his eyes were still firm. "No matter what it is, we are not afraid!"

Feng Yu bit her lips gently. Although the flame in her hand was already very weak, she still tried to make it burn more vigorously to illuminate the road ahead for everyone.

The black shadow was like a ghost in the dark night, silently approaching the source of the sound, and the short blade flashed coldly in the darkness.

Lin Yue tightly grasped the staff and leaned against the cave wall, trying to recover some magic power. "This voice seems to have some kind of magic power, which makes me feel dizzy."

Everyone walked cautiously in the direction where the sound came from. The ground under their feet became more and more rugged and uneven, and stones fell from above their heads from time to time.

"Everyone, pay attention to the top of your head!" Li Yunfei reminded loudly.

Suddenly, a narrow passage appeared in front of them, and the sound came from deep inside the passage. Strange lights flickered on the walls on both sides of the passage, as if countless pairs of eyes were watching them.

Li Yunfei took a deep breath and walked into the passage first. The passage was filled with a rotten smell, which made people feel sick.

"What on earth is this place?" Zhang Hao couldn't help but ask.

No one answered him because everyone's attention was attracted by the mysterious voice.

As they went deeper, the sounds became clearer and more eerie.

Feng Yu's heartbeat quickened rapidly. She felt an invisible pressure gradually enveloping them. "I... I'm a little scared."

"Don't be afraid, we are here." Li Yunfei comforted.

Mo Ying suddenly stopped in front of him and said, "There is something ahead."

Everyone looked closely and saw a huge stone chamber at the end of the passage. In the center of the chamber was a huge sarcophagus, and the sound came from the sarcophagus.

Li Yunfei slowly approached the sarcophagus, and the light of the artifact illuminated the surface of the sarcophagus. The sarcophagus was engraved with complex runes and patterns, exuding an ancient and mysterious atmosphere.

"What is this?" Zhang Hao asked.

Li Yunfei shook his head. "I don't know either, but this sound came from here."

At this moment, the sarcophagus suddenly trembled violently, as if something was about to rush out of it.

"Everyone retreat!" Li Yunfei shouted loudly.

Everyone stepped back and stared at the sarcophagus nervously.

Suddenly, the lid of the sarcophagus slowly opened, and a black smoke poured out from it, instantly filling the entire stone chamber.

Li Yunfei and others were shrouded in smoke and their vision became blurred.

"Be careful!" Li Yunfei's voice echoed in the smoke.

A sinister laugh came from the smoke, sending chills down one's spine.

"Who is it?" Zhang Hao asked loudly.

No one answered him, only the laughter continued to echo in their ears.

Lin Yue tried to cast magic to disperse the smoke, but her magic power had been exhausted and she was unable to cast any effective magic.

Just when everyone was in despair, the artifact suddenly burst out with a powerful light, instantly dispersing the smoke.

The smoke cleared, and everyone finally saw the scene in the sarcophagus. A figure slowly stood up from the sarcophagus, emitting a strong dark aura that made people shudder.

"You're finally here." said the figure, his voice sounding like it came from hell.

Li Yunfei held the artifact tightly, "Who are you?"

The figure sneered, "I am the Avenger awakened by you. You will all die here!"

After saying that, he waved his hands, and a powerful dark force attacked Li Yunfei and others.

The powerful dark force was like a surging black wave, overwhelming Li Yunfei and others. Li Yunfei instantly held the artifact in front of him, shining brightly, trying to resist the force.

"Everyone concentrate your strength!" He shouted loudly, and his voice echoed in the small stone chamber.

Zhang Hao gritted his teeth and thrust his spear forward. The tip of the spear flashed with silver light and collided with the dark power, making a "sizzling" sound. Veins on his forehead bulged and sweat fell like rain.

Feng Yu waved her hands, and the flames ignited again. She tried to use the power of the flames to dispel the darkness. However, the dark power seemed to be able to devour everything, and the flames were suppressed and dimmed the moment they came into contact with it.

Mo Ying's figure was like a ghost, and his short blade flashed cold rays in the darkness. He relied on his agility to shuttle through the cracks in the dark power, looking for an opportunity to counterattack.

Lin Yue held the staff tightly in both hands, chanting ancient and complex spells, trying to cast a stronger protective magic for everyone. But her magic power was almost exhausted, and every spell she chanted seemed extremely difficult.

The dark power continued to attack them. Li Yunfei and others retreated step by step, and cracks began to appear on the ground under their feet.

"We can't be defeated like this!" Li Yunfei roared, his eyes flashing with determination. The power in his body continued to flow into the artifact, and the light of the artifact gradually increased, forming a stalemate with the dark power.

The Avenger in the darkness sneered: "Your resistance is futile, just become my prey!" His voice was as cold and evil as if it came from the abyss of Hell.

Zhang Hao responded loudly: "Don't even think about it! We will never surrender!" His voice was full of indomitable spirit and anger.

Feng Yu shouted and increased the output of the flames again. Her eyes revealed a determination: "Even if I have to use up my last bit of strength, I will fight you to the end!"

Mo Ying remained silent, but the short blade in his hand swung even faster, with every attack carrying the determination to kill.

Lin Yue finally completed the spell, and a light blue light enveloped everyone, temporarily relieving the oppression of the dark power.

Li Yunfei took the opportunity to launch a counterattack, and the artifact stabbed at the Avenger with a dazzling light. The Avenger dodged the attack easily by moving sideways. He raised his hand and waved it, and a dark shock wave attacked Li Yunfei.

Li Yunfei was knocked back several steps and spat out a mouthful of blood.

"Li Yunfei!" everyone exclaimed.

"I'm fine, keep fighting!" Li Yunfei wiped the blood from the corner of his mouth and rushed forward again.

At this moment, the atmosphere in the stone chamber was extremely tense, and everyone's breathing became rapid and heavy.

The Avengers' attacks became more and more fierce, and the dark power swept in like a storm. Li Yunfei and others' defenses gradually collapsed, and they all had many wounds on their bodies.

Zhang Hao's spear was already cracked, and his strength was about to run out. Feng Yu's flame became as weak as a candle in the wind, Mo Ying's movements became slow, and Lin Yue was even more shaky.

Just when everyone was in a desperate situation, Li Yunfei suddenly felt a mysterious power awakening in his body. This power was warm and powerful, and instantly filled his whole body.

"This is..." Li Yunfei was shocked.

He raised the artifact again, and the light from the artifact became extremely dazzling, illuminating the entire stone chamber.

"Let's end this!" Li Yunfei shouted loudly.

Everyone felt the change in him, and they all pulled themselves together, gathering their last bit of strength.

Under the shining of this light, the figures of the Avengers began to become blurred and the dark forces gradually faded away.

"No! This is impossible!" The Avenger roared in despair.

But his resistance was of no avail. With a flash of strong light, the dark power completely dissipated and the Avengers disappeared without a trace.

Li Yunfei and others collapsed to the ground, gasping for breath.

"We...we won..." Zhang Hao said weakly.

Everyone smiled at each other, their eyes filled with joy at surviving the disaster.

However, before they had time to celebrate, the stone chamber began to shake violently and rocks kept falling from above their heads.

"Oh no, this place is going to collapse!" Li Yunfei shouted.

Everyone struggled to stand up and ran towards the exit.

Behind them, the stone chamber continued to collapse, as if to bury them forever in this darkness...
