Genshin Impact.

Under the guidance of the old man, Lin Feng and Li Er embarked on a journey full of unknowns. One day, they came to a mysterious valley filled with thick fog, and the surroundings were so quiet that it made people feel a little uneasy.

"Brother Lin Feng, it feels so mysterious here. Is there any danger?" Li'er held the corner of Lin Feng's clothes tightly, with a hint of worry in her eyes.

Lin Feng gently patted Li'er's hand and comforted her: "Don't be afraid, I'm here. Since it was fate that led us here, there must be a reason."

The two walked into the valley carefully, and as they went deeper, they found an ancient ruin. The door of the ruin was closed, but it was engraved with mysterious runes and patterns.

Lin Feng walked forward and carefully observed the runes, trying to decipher the secrets in them. At this moment, the old man's voice sounded in his mind: "This is an ancient relic, which contains endless opportunities, but also comes with many dangers. You must be careful."

Lin Feng nodded, then looked at Li'er, and the two decided to push open the mysterious door. The moment their hands touched the door, a powerful force sucked them in.

After entering the ruins, there was a huge palace inside. Strange lights flickered on the walls of the palace, and complex formations were engraved on the ground. Lin Feng looked around vigilantly, holding his sword tightly in his hand.

Li'er looked around curiously. Suddenly, a huge puppet emerged from the wall and attacked them with its fists waving. Lin Feng quickly protected Li'er behind him and raised his sword to face the puppet.

After a fierce battle, Lin Feng finally found the puppet's weakness and defeated it. However, this was just the beginning, as more puppets came from all directions.

"Li'er, you hide aside carefully, I will deal with them." Lin Feng said loudly.

Li'er shook her head firmly: "Brother Lin Feng, I also want to fight. I can't always hide behind you."

After that, Li'er used her magic, and beams of light flew towards the puppets. With the tacit cooperation of the two, the puppets were defeated one by one.

After solving the threat of the puppets, they continued to go deeper into the palace. Deep in the palace, they found a huge treasure chest. Lin Feng carefully opened the treasure chest, and a dazzling light burst out from it.

After the light disappeared, they saw an ancient secret book and a mysterious magic weapon in the treasure chest. Lin Feng picked up the secret book, opened it, and found that it recorded a powerful immortal method.

"With this secret book, our strength will definitely be improved to a higher level." Lin Feng said excitedly.

Li'er picked up the magic weapon, which emitted a powerful wave of power. "This magic weapon is so powerful, it will definitely help us cope with the next challenge."

Just as they were rejoicing over the treasure, a violent tremor suddenly broke out in the ruins. The ground began to collapse, and cracks appeared on the walls.

"Oh no, the ruins are about to collapse, let's get out quickly." Lin Feng pulled Li'er and ran towards the exit.

However, at the exit, a powerful barrier blocked their way. Lin Feng tried to break the barrier with his sword, but it remained motionless.

"What should we do, Brother Lin Feng? We can't get out." Li'er said anxiously.

Lin Feng took a deep breath to calm himself down. He began to recall the immortal methods in the secret book he had just obtained, trying to find a way to break the barrier.

After some effort, Lin Feng finally comprehended a powerful spell. He cast the spell, and a beam of light shot towards the barrier. Under the illumination of the light, the barrier gradually became weaker.

Finally, with a loud bang, the barrier was broken, and Lin Feng and Li'er successfully escaped from the ruins.

After walking out of the ruins, they found that the outside world had changed. The originally peaceful valley became desolate, and an evil atmosphere permeated the surroundings.

"It seems that our adventure has just begun." Lin Feng looked at the scene in front of him, his eyes full of determination.

Li'er nodded: "No matter what difficulties we encounter, we will face them together."

The two held hands and continued their journey to immortality...
