Genshin Impact.

Lin Feng, Li'er and the old man did not dare to stop for a moment on the road to their mission. They passed through dense forests, crossed turbulent rivers, and came to the foot of a high mountain surrounded by clouds and mist.

The mountain was so high that it reached the clouds, and its steepness seemed like a stairway to the sky. Lin Feng looked up at the top of the mountain, and an inexplicable awe welled up in his heart.

"This mountain must be hiding many unknown challenges." Li'er said softly.

The old man nodded slightly: "But we have no choice, our mission is calling us forward."

The three of them began to climb the mountain. The mountain road was rugged and difficult to walk on, and the stones under their feet kept rolling down. Lin Feng walked in front, carefully clearing the way for Li'er and the old man.

Suddenly, a strong wind blew and they were almost unable to stand. Lin Feng held on to the rocks beside him tightly and shouted, "Everyone be careful!"

Li'er tried hard to keep her body steady, but was still nearly blown down by the wind. At this moment, the old man stretched out his hand, and a gentle force protected Li'er.

After the wind died down, they continued on their way, but before they had gone far, a huge bird flew over their heads, casting a shadow.

The bird's feathers burned like flames, and its eyes were sharp and fierce. It circled once, then swooped down towards Lin Feng.

Lin Feng was not afraid at all, he raised the sword in his hand to face the bird. The bird's sharp claws collided with Lin Feng's sword, making a harsh sound.

Li'er cast a spell on the side, shooting rays of light at the bird, trying to distract its attention.

But the bird was very agile and avoided Li'er's spell, attacking Lin Feng again. Lin Feng dodged sideways and took the opportunity to stab the bird's wings.

The bird cried out in pain and flew away. But it did not leave, but circled in the air, looking for another opportunity to attack.

"This is not a solution. We must find a way to repel it." Lin Feng said.

The old man pondered for a moment and said, "Let me try."

The old man put his hands together and muttered something. A strong force emanated from him. Fei Niao felt this force and showed a trace of fear.

Taking this opportunity, Lin Feng swung his sword again, and a stream of sword energy shot towards the bird. The bird was unable to dodge, was hit by the sword energy, and flew away in embarrassment.

They continued to climb and finally reached the middle of the mountain. There was a cave with a mysterious atmosphere.

Lin Feng walked into the cave cautiously, and saw strange light flashing on the cave wall, as if telling an ancient secret.

Li Er curiously approached the cave wall and wanted to touch the light. The old man quickly stopped her and said, "Be careful, this could be dangerous."

Before he finished speaking, the light on the cave wall suddenly became stronger, forming a huge vortex. A strong suction force pulled them into the vortex.

Lin Feng struggled hard, trying to break free from the suction. Li'er held onto Lin Feng's arm tightly, her face full of fear.

The old man cast a spell again, trying to fight against the suction. With the old man's efforts, the suction gradually weakened, and they finally got rid of the danger.

After leaving the cave, they continued to move towards the top of the mountain. After some hard work, they finally reached the top.

There was an ancient temple on the top of the mountain, and the door of the temple was closed. Lin Feng walked forward and gently pushed the door, but the door did not move at all.

Li'er said, "Maybe we need to solve some puzzle to open this door."

They began to look for clues around the temple and finally found some strange symbols on a stone tablet.

The old man studied the symbols carefully, and after a moment he said, "This is an ancient sealing spell. We must recite these spells in a specific order to open the gate."

Lin Feng, Li'er and the old man worked together and recited the spell in the order the old man said.

The door of the temple slowly opened, and a dazzling light shone out from the door. They walked into the temple and saw a mysterious treasure enshrined inside, which exuded powerful power.

Just as they approached the treasure, a mysterious voice sounded in the temple: "If you want to get the treasure, you must pass the final test."

Immediately afterwards, countless phantoms appeared in the temple, each of which possessed powerful power.

Lin Feng, Li'er and the old man looked at each other, their eyes full of determination. They knew that this was the last stage of their mission, and they had to get through it no matter what...
