Genshin Impact.

Lin Feng and Li'er stood side by side at the entrance of the Immortal Demon Abyss, surrounded by gloomy fog and faintly heard bursts of creepy roars. Their eyes were firm and fearless, and the faith in their hearts was like a burning flame, illuminating this dark abyss.

Lin Feng took a deep breath, holding the spirit sword tightly in his hand, the sword body flickered with a faint light, as if responding to his inner determination. Li Er flicked her sleeves lightly, exuding a faint fairy aura, adding a mysterious atmosphere to the two of them.

"Li'er, there are many dangers in the Immortal Demon Abyss. Are you afraid?" Lin Feng turned his head and looked at Li'er beside him, his eyes full of concern.

Li Er smiled slightly, with a firm look in her eyes: "With you by my side, I have nothing to fear."

Lin Feng nodded, the two smiled at each other, and then walked into the Immortal Demon Abyss together with firm steps.

As soon as they entered the Immortal Demon Abyss, a strong pressure came over them, as if to crush them into pieces. Lin Feng used his immortal power to form a shield in front of him, protecting himself and Li'er. Li'er was not to be outdone, she formed seals with her hands and cast a defensive spell, which echoed with Lin Feng's shield.

"Be careful!" Lin Feng suddenly shouted, and saw a huge black claw stretched out from the darkness and grabbed them. Lin Feng shouted, swung the spirit sword, and a sharp sword energy slashed at the claw. The claw collided with the sword energy, making a loud noise, and then retracted.

The two continued to move forward, and the scene around them became more and more bizarre. Black blood flowed on the ground, strange runes crawled on the walls, and a pungent smell filled the air.

"This Immortal Demon Abyss is indeed as famous as it is said to be, and is full of dangers everywhere." Li'er said with a frown.

"But the more dangerous it is, the more likely you are to get an opportunity. We just need to be careful." Lin Feng comforted.

Suddenly, a low roar came from the front, and a huge monster appeared in front of them. The monster was burning with black flames, its eyes were flashing red light, and a stream of black flames spewed out of its mouth, sweeping towards them.

Lin Feng and Li'er quickly separated, each using their magic to respond. Lin Feng waved his magic sword, and the light on the sword became brighter and brighter, turning into a huge sword shadow, slashing towards the monster. Li'er waved her hands, and a stream of magic light flew out from her hands, turning into fairy birds, rushing towards the monster.

The monster roared under the attack of the two, but still resisted stubbornly. Lin Feng and Li'er cooperated with each other and continued to attack the monster. After a fierce battle, the monster finally fell to the ground.

"Huh...finally solved." Lin Feng breathed a sigh of relief and wiped the sweat from his forehead.

Li'er walked up to Lin Feng and said, "This is just the beginning. There may be more powerful enemies in the future."

The two continued to move forward, encountering various dangerous traps and powerful enemies along the way, but they relied on their strong will and superb magic skills to overcome danger time and time again.

Deep in the Immortal Demon Abyss, they found an ancient palace. The door of the palace was closed and engraved with mysterious runes.

"This palace looks very unusual. Maybe there are some secrets hidden inside." Lin Feng said.

Li'er nodded, and the two of them walked forward and tried to push open the palace door. But no matter how hard they tried, the door didn't budge.

"It seems that we need to solve the puzzle of these runes before we can open the door." Li'er said as she carefully observed the runes on the door.

Lin Feng also began to study these runes, and the two fell into deep thought. After some effort, they finally found the pattern of the runes, successfully solved the puzzle, and the door slowly opened.

The palace is filled with an ancient atmosphere, with mysterious scrolls hanging on the walls and various precious magic weapons placed on the ground.

"These magic weapons look very powerful." Lin Feng said.

"But we can't be fooled by these magic weapons. Let's explore other places in the palace first." Li'er reminded.

The two were exploring the palace cautiously when suddenly a dark shadow flashed past them from behind.

"Who?" Lin Feng turned around vigilantly, but saw nothing.

"Be careful, there may be other people in this palace." Li'er said.

At this moment, a sinister laugh came from all around: "Hahahaha, you two actually dared to break in here, you are really courting death."

Lin Feng and Li Er looked at each other, their hearts full of vigilance. They looked around, trying to find the source of the laughter.

"Come out! What's the point of hiding your head and showing your tail?" Lin Feng said loudly.

"Hmph, since you want to die, then I will grant your wish." As the voice fell, a figure appeared in front of them.

The man was dressed in a black robe, had a ferocious face, and his eyes were flashing with evil light.

"Who are you? Why are you here?" Li'er asked.

"I am the guardian of this Immortal Demon Abyss. Your intrusion into this place is a provocation to me." said the man in black robe.

"Guardian? We are just here to look for opportunities and have no intention of offending you." Lin Feng said.

"Hmph, stop talking nonsense and prepare to die!" said the man in black robe, and a black spear appeared in his hand, stabbing towards Lin Feng.

Lin Feng dodged sideways, swung his magic sword, and started a fierce battle with the man in black robe. Li'er also performed magic to assist Lin Feng.

The black-robed man was very powerful, and Lin Feng and Li'er gradually fell into a disadvantage. But they did not give up and still resisted tenaciously.

At the critical moment, Lin Feng suddenly comprehended a new magic. He injected the magic power into the magic sword. The sword shone brightly and turned into a huge ray of light, slashing towards the man in black.

Seeing this, the black-robed man's face changed drastically, and he wanted to dodge, but it was too late. The light slashed the black-robed man and knocked him out.

"Good opportunity!" Li'er took the opportunity to perform a powerful magic and completely defeated the man in black.

"Finally solved." Lin Feng said, panting.

Li'er walked up to Lin Feng and said, "This time it's all thanks to you for understanding the new magic technique."

"Let's continue exploring the palace, maybe we will find other things." Lin Feng said.

The two continued to explore the palace, and deep inside the palace, they found an ancient secret book, which recorded a powerful method of practicing immortal arts.

"This secret book will definitely be of great help to our practice." Lin Feng said.

Li'er nodded, and the two began to study the contents of the secret book carefully.

Just as they were immersed in the secret book, the palace suddenly began to shake violently, and cracks appeared on the surrounding walls.

"Oh no, the palace is going to collapse!" Lin Feng shouted.

The two of them hurriedly ran out of the palace. The moment they ran out of the palace, the palace collapsed and turned into ruins.

"That was a close call!" Li'er said with lingering fear.

"Although this trip to the Immortal Demon Abyss was full of dangers, we also gained a lot." Lin Feng said.

The two left the Immortal Demon Abyss with their harvest. Their immortal journey is still going on, and there are more challenges waiting for them in the future...
