Genshin Impact.

Under the guidance of the old man, Lin Feng and Li Er embarked on a mission full of unknowns and challenges. Along the way, they experienced countless hardships and obstacles, but never had the slightest intention of retreating.

At this moment, they were in a desolate valley, surrounded by thick fog, making it difficult to tell the direction. Lin Feng looked around vigilantly, the spirit sword in his hand flashing a faint light. Li'er followed closely beside him, her eyes revealing determination and courage.

"Brother Feng, this fog is so strange, we have to be careful." Li'er said softly.

Lin Feng nodded, "Well, follow me closely and don't get separated."

As they moved forward cautiously, suddenly, a gust of wind blew past, dispersing part of the fog and revealing a rugged path ahead. On both sides of the path, there were jagged rocks, as if hiding countless dangers.

Lin Feng and Li'er walked along the path, hearing eerie cries from time to time. Suddenly, a huge python jumped out from the tree next to them and pounced on them with its bloody mouth wide open.

Lin Feng reacted quickly, wielding the sword in his hand, and a stream of sword energy slashed at the python. The python nimbly avoided the sword energy, twisted its body, and pounced again. Li'er was not to be outdone, and offered a ribbon in her hand, which turned into a stream of light and wrapped around the python.

With the cooperation of the two, the python gradually lost the upper hand. Finally, Lin Feng saw the right moment and stabbed the python with his sword, killing it completely.

After dealing with the python, they continued on their way. Soon, an ancient temple appeared before them. The door of the temple was closed, but a mysterious power came from inside.

Lin Feng walked forward and gently pushed the door, but found that it did not move at all. "This door seems to be sealed by some force." He frowned and said.

Li'er observed the gate carefully, then said, "Brother Feng, perhaps we need to find a way to break the seal."

Just as they were looking for clues everywhere, some strange runes suddenly appeared on the wall of the temple. Lin Feng stared at these runes and fell into deep thought. After a while, he seemed to have thought of something and began to touch these runes in a certain order.

As Lin Feng moved, the seal on the gate flickered and slowly dissipated. The gate slowly opened, and an old breath came to their faces. They walked into the temple and saw a mysterious statue enshrined inside. The eyes of the statue flickered with strange light, as if watching them.

"This statue is so strange, I wonder what the secret is." Li'er said softly.

Lin Feng approached the statue and observed it carefully. Suddenly, a beam of light spurted out from the statue's mouth, enveloping Lin Feng. Li Er was horrified and wanted to rush over to save Lin Feng, but was blocked by an invisible force.

Lin Feng felt his body being pulled by a strong force, and his consciousness gradually blurred. After an unknown amount of time, when he opened his eyes again, he found himself in an unfamiliar space.

The space was filled with colorful light, and there was nothingness all around. Lin Feng looked around vigilantly, trying to find a way out. At this moment, a voice sounded in his ears: "Lin Feng, do you know your mission?"

Lin Feng asked loudly: "Who are you? What is my mission?"

The voice replied: "I am the guardian of this space. Your mission is to save the people and prevent an impending disaster. But before that, you must pass many tests and improve your strength."

After saying that, the light around him began to gather and turned into powerful enemies, rushing towards Lin Feng. Lin Feng clenched the spirit sword in his hand and faced the enemy.

On the other side, Li'er was anxiously waiting for Lin Feng. Suddenly, she felt a strong force wave, and the temple began to shake violently. Li'er's heart tightened, "Brother Feng, you must be safe."

At this time, Lin Feng was fighting hard in that mysterious space. Every move he made contained powerful immortal power. During the battle, he constantly comprehended new moves and his strength was constantly improving.

After a fierce battle, Lin Feng finally defeated all the enemies. A portal appeared in the space, and Lin Feng walked in without hesitation.

Lin Feng passed through the portal and returned to the temple. Li Er saw that he had returned safely and excitedly threw herself into his arms.

"Brother Feng, you're finally back. I was so worried about you." Li'er said.

Lin Feng patted Li'er's back gently, "I'm fine, sorry to have made you worry."

At this time, the old man appeared in the temple. He looked at Lin Feng and nodded with satisfaction, "Yes, you have passed the test. Next, you will face more severe challenges."

Lin Feng and Li'er looked at each other, then said firmly: "We are ready."

The old man smiled and said, "Okay, let's go."

They walked out of the temple and continued on their journey of mission. What awaited them ahead were unknown challenges and opportunities...
