Genshin Impact.

Lin Feng and Li'er struggled to move forward in the foggy realm of the Immortal Path. The fog around them seemed to never dissipate. The old man looked solemn and worried about their future.

"This fog is so strange that it makes me feel lost." Lin Feng said with a frown.

Li'er followed Lin Feng closely, "Brother Feng, don't be afraid, we will definitely find a way out."

They explored carefully, and every step was full of unknown dangers. Suddenly, a gust of wind whistled past, making it almost impossible for them to open their eyes.

When the wind died down, they found themselves in a strange place, surrounded by a desolate landscape without a trace of life.

"Where is this?" Li'er asked.

Lin Feng shook his head, "I don't know either, but I feel there is a mysterious atmosphere here."

The old man stepped forward and observed the surroundings. "Be careful, this place may not be simple."

At this moment, a low roar was heard in the distance, and the three of them immediately became alert.

I saw a huge monster slowly walking out of the darkness. Its body was huge and it exuded a powerful pressure.

Lin Feng clenched the sword in his hand, "Don't be afraid, we will deal with it together."

The three of them started a fierce battle with the monster. Lin Feng displayed his exquisite sword skills, Li Er used magic to assist, and the old man instructed their tactics on the side.

After a hard fight, they finally repelled the monster. However, before they had time to catch their breath, more dangers came.

Mysterious runes appeared in the mist, emitting strange light. Lin Feng tried to decipher these runes, but found them difficult to understand.

"This rune seems to hide some mystery." said the old man.

Li'er thought for a moment, "Perhaps this is the key to unlocking this foggy world."

So, they began to concentrate on studying these runes. Through constant attempts and explorations, Lin Feng gradually got some clues.

"I seem to understand some rules." Lin Feng said excitedly.

Based on his findings, the three worked together and finally cracked the secret of the rune.

As the runes disappeared, the fog began to dissipate, and a passage appeared before them.

"Maybe this is the way out." Lin Feng said.

They moved forward along the passage and encountered various traps along the way, but they resolved them one by one.

Finally, they walked out of the fog and came to a quiet valley.

"Finally it's out." Li'er breathed a sigh of relief.

However, before they could enjoy this moment of peace, they discovered that a greater crisis was hidden in the valley.

There was an evil atmosphere in the valley, which made people shudder.

"Be careful, something's happening." the old man warned.

A group of dark shadows came from all directions and pounced on them.

Lin Feng and others were once again caught up in the battle...

During the battle, Lin Feng discovered that these black shadows were not ordinary enemies. They seemed to be controlled by some powerful force.

"We must find out the mastermind behind this, otherwise it will be difficult for us to escape." Lin Feng said.

They fought and searched for clues, and finally found a cave hidden deep in the valley.

"The key may be in that cave." Li'er said.

The three of them walked towards the cave without hesitation. There was a pungent smell in the cave and strange lights flickered on the walls.

Deep in the cave, they saw a huge magic array.

"It turns out that this magic formation is causing trouble." said the old man.

Lin Feng decided to destroy the magic array and resolve the crisis. He used all his strength to rush towards the magic array.

At the critical moment, Li'er and the old man also used their unique skills to help Lin Feng.

With a flash of strong light, the magic array was successfully destroyed.

The evil aura in the valley also dissipated, and the dark shadows disappeared without a trace.

Lin Feng and others finally got rid of the crisis and continued on their journey to immortality.

However, they know that there are more challenges waiting for them ahead...
