Genshin Impact.

After experiencing all kinds of hardships, Lin Feng and Li'er turned their hearts to the light. However, the shadow was lurking in the dark, waiting for the opportunity to give them a fatal blow.

They continued to move forward in the mortal world and came to an ancient town called Qingyun. This ancient town seemed peaceful and tranquil, but in fact it was full of mysteries. With his keen intuition, Lin Feng sensed a hint of something unusual.

In the town, they met a mysterious old man. The old man had deep eyes, as if he knew everything in the world. The old man told them that this ancient town was shrouded by an evil force, and the source of this force was a dark cave hidden underground.

Lin Feng and Li Er decided to go deeper into the cave to find out what was going on. The cave was filled with strange fog, making it difficult to tell the direction. They moved forward cautiously, and suddenly, a group of dark creatures came from all directions.

Li'er used her magic, the light shone, and she temporarily repelled the dark creatures. But these creatures kept coming, as if they could never be killed. Lin Feng realized that they had to find the source of the dark power to completely solve the problem.

Deep in the cave, they found a huge magic circle. The magic circle exuded an evil aura and continuously absorbed the surrounding spiritual energy. Lin Feng concluded that this was the core of the dark power.

Just as they were about to destroy the magic circle, a black shadow emerged from the circle. The black shadow was huge and exuded a strong oppressive force. He sneered at Lin Feng and Li Er and said, "Do you think you can easily destroy my plan? Too naive!"

Lin Feng was not afraid at all, holding a long sword, he rushed towards the shadow. Li Er assisted him and used magic to bless Lin Feng. The two sides started a fierce battle.

The black shadow was very powerful, and Lin Feng and Li Er gradually fell into trouble. But their faith in their hearts never wavered, and they still resisted tenaciously.

At the critical moment, the immortal power in Lin Feng's body suddenly burst out, shining brightly. The black shadow was frightened by this sudden power and revealed a flaw. Li'er took the opportunity to launch a fatal attack and hit the black shadow's vital point.

The shadow screamed and disappeared into the darkness. The magic circle also shattered, and the dark power gradually dissipated.

Lin Feng and Li Er successfully saved Qingyun Ancient Town, and their reputation spread among the mortals. However, they knew that this was just a small episode in their long journey to immortality.

After leaving Qingyun Ancient Town, they continued on their way. In a forest, they met an injured immortal. The immortal told them that something had happened in heaven and a mysterious force was secretly controlling everything.

Lin Feng and Li Er decided to return to heaven to find out the truth. After going through untold hardships, they finally returned to heaven.

In the Heavenly Palace, the atmosphere was heavy. Lin Feng and Li Er discovered that many immortals were controlled by a strange spell and had lost their self-awareness.

They searched for clues in the heaven and finally found a hidden secret room. In the secret room, there was a mysterious ancient book, which recorded an evil spell that could control the minds of immortals.

Just as they were about to take the ancient book away, a group of mysterious people appeared and stopped them. These mysterious people were powerful and well-trained.

A fierce battle broke out again. Lin Feng and Li Er worked closely together to fight a desperate battle with the mysterious man.

During the battle, Lin Feng gradually comprehended a new and powerful magic. He used this magic to defeat many mysterious people in one fell swoop.

However, there was a more powerful leader who had not yet made a move. The leader showed a ferocious smile and said to Lin Feng and Li'er: "You can't escape, just surrender!"

Lin Feng and Li'er did not back down. They decided to fight to the death with the leader to protect the peace and justice of heaven.

Finally, after a thrilling battle, Lin Feng and Li Er defeated the leader with their firm belief and strong strength, successfully exposed the conspiracy of the mysterious forces and saved the heaven.

After this series of tests, Lin Feng and Li'er's immortal path becomes brighter, and their names will be forever engraved in the history of the immortal world.
