Genshin Impact.

Under the guidance of the old man, Lin Feng and Li Er continued their journey to immortality. This time, they came to a mysterious valley, where it was rumored that powerful immortal secrets and precious magic weapons were hidden.

As soon as he stepped into the valley, Lin Feng immediately sensed an unusual atmosphere. The surroundings were so quiet that it made people feel creepy, and only the occasional roar of unknown beasts broke the silence.

"Lier, be careful." Lin Feng said softly, while vigilantly observing the movements around him.

Li'er nodded and followed Lin Feng closely.

Suddenly, a gust of wind whistled past, and there seemed to be a strange energy in the wind. Lin Feng's heart tightened, and he quickly cast a defensive magic to cover himself and Li'er.

After the storm, a huge two-headed monster appeared in front of them. This monster was huge and exuded a terrifying aura.

Lin Feng took a deep breath and said, "Li'er, step back and I'll deal with it."

After that, Lin Feng mobilized the immortal power in his body and performed a powerful attacking immortal technique. A beam of light shot out from his hand and rushed straight towards the monster.

The monster roared and swung its huge claws towards the light. The two collided, causing a huge explosion.

Lin Feng took advantage of this opportunity, flashed towards the monster, and engaged in close combat with it.

Li'er watched anxiously from the side, but did not dare to step forward rashly. She could only pray silently for Lin Feng.

After a fierce battle, Lin Feng finally found the monster's weakness and defeated it in one fell swoop.

However, before they could catch their breath, a series of traps and mazes appeared in the valley.

In the maze, Lin Feng relied on his keen perception and clever use of magic to avoid danger again and again. Li'er also used her intelligence to help Lin Feng solve many puzzles.

Finally, they walked out of the maze and came to an ancient cave.

At the entrance of the cave, a powerful barrier blocked their way.

Lin Feng closed his eyes, carefully feeling the power fluctuations of the barrier, trying to find a way to break it.

After some effort, he discovered that the weakness of the barrier lay in the gap in the flow of its energy.

Lin Feng concentrated his mind and performed a special magic technique, successfully breaking the barrier.

Entering the cave, they found an ancient secret book of immortality. Lin Feng excitedly picked up the secret book and began to study it.

During the study process, Lin Feng encountered many difficulties, but he overcame them bit by bit with his firm will and love for immortal arts.

Li'er stood by to protect him and prevent any accidents from happening.

After several days of practice, Lin Feng finally comprehended the powerful magic in the secret book.

However, just as they were about to leave the cave, a figure suddenly appeared in front of them and blocked their way. This figure exuded a powerful aura, which made people feel depressed and uneasy.

"This secret book is mine, don't even think about taking it away!" The mysterious strong man said coldly. His voice was full of confidence and majesty, as if he had mastered everything.

Lin Feng was not afraid at all. He took a step forward and said, "We are lucky enough to have this secret book. Don't even think about snatching it away." His eyes were firm and resolute, and he showed no intention of retreating.

The mysterious strong man raised his lips slightly, revealing a disdainful smile. He waved his hands, showing no sign of retreating.
