Genshin Impact.

Lin Feng holds on to his beliefs in the fog of the immortal path, but the road ahead is still full of unknowns and challenges.

Li'er accompanied Lin Feng, her eyes full of concern and worry for him. The mysterious place they were in was filled with fog that seemed to have the power to confuse people, making it difficult to tell the direction.

The old man observed their every move from a distance, secretly wondering whether Lin Feng could break through these difficulties.

Lin Feng frowned and tried to use his power to dispel the fog, but the effect was minimal. He knew that relying on strength alone would not solve the problem at hand, and he had to find the source of the fog.

Li'er said softly: "Lin Feng, don't be anxious, maybe we should calm down and look for the pattern in it." Lin Feng nodded, took a deep breath, and calmed himself down.

They began to carefully observe the surrounding environment and found that the concentration of the fog would change with time and their actions. Lin Feng speculated that this might be a phenomenon caused by a formation.

Therefore, Lin Feng began to recall the knowledge of the formation he had learned, trying to find a way to crack it. Li'er also helped, relying on her keen perception, she provided Lin Feng with some subtle clues.

After some effort, Lin Feng finally found a flaw in the formation. However, just as they were about to break the formation, a group of mysterious figures suddenly appeared around them and attacked them.

These figures moved quickly and attacked in strange ways, which put Lin Feng and Li'er in a passive position for a while. But Lin Feng quickly adjusted his state and used powerful immortal magic to fight fiercely with these mysterious figures.

Li'er assisted Lin Feng and protected him. During the battle, Lin Feng gradually discovered that these mysterious figures did not seem to be real entities, but were transformed by the fog.

He realized that in order to completely get rid of these attacks, he must first break the fog formation. So, while dealing with the attacks, Lin Feng continued to look for the key to the formation.

After a life-and-death struggle, Lin Feng finally found the core of the formation. He concentrated all his strength and performed a powerful magic to directly hit the core of the formation.

There was a loud noise, and the fog instantly dissipated, and the scene in front of them gradually became clear. However, before they could breathe a sigh of relief, they found themselves in an unfamiliar valley.

There was a strange atmosphere in the valley, and the surrounding stone walls were engraved with strange runes. Lin Feng looked around vigilantly, secretly on guard.

Li'er said: "Lin Feng, this place is very strange, we need to be careful." Lin Feng nodded, and walked forward carefully with Li'er.

As they walked, they found an ancient cave in front of them. The door of the cave was closed, but a strong power wave came from inside.

Lin Feng hesitated for a moment, but finally decided to push open the door of the cave. As soon as the door opened, a strong suction force sucked them in.

After entering the cave, they found a different world inside. Various precious magic weapons and secret books were placed around, but Lin Feng was not confused by these things. His eyes were always looking for the exit.

At this moment, a voice suddenly rang out from the cave: "Since you are here, don't think of leaving easily." Lin Feng said loudly: "Who are you, the evildoer who is hiding his head and showing his tail? Show yourself if you have the guts."

As the voice sounded, a huge figure appeared in front of them. This figure exuded a strong pressure, making Lin Feng and Li'er feel difficult to breathe.

But Lin Feng did not retreat, he stepped forward and started a desperate fight with this huge figure. During the battle, Lin Feng gradually discovered that although this figure was powerful, it had obvious flaws.

He seized the opportunity and used his strongest magic to hit the flaw of the figure. The figure fell to the ground with a bang and disappeared into a beam of light.

After resolving this crisis, Lin Feng and Li'er continued to search for an exit in the cave. Finally, they found a teleportation array deep in the cave.

Lin Feng and Li'er stepped into the teleportation array without hesitation. With a flash of light, they were teleported to an unfamiliar place.

This is a barren desert, with the sun shining brightly in the sky and the heat unbearable. Lin Feng and Li'er are struggling to move forward in the desert, their physical strength is constantly being consumed.

Just when they were about to give up, an oasis suddenly appeared in the distance. They seemed to see hope and ran towards the oasis desperately.

After arriving at the oasis, they found an ancient temple. The door of the temple was open, and it seemed that there was some secret hidden inside.

Lin Feng and Li'er walked into the temple and found a mysterious statue enshrined inside. There was a strange light flashing in the eyes of the statue, as if it was telling something.

Lin Feng carefully observed the statue and suddenly found that the statue was holding a jade pendant. He picked up the jade pendant and felt a cool force entering his body, which immediately restored a lot of physical strength.

At this moment, a space-time crack suddenly appeared in the temple, and a powerful force sucked Lin Feng and Li'er into the crack.

When they opened their eyes again, they found themselves back in a familiar place. The old man was standing in front of them with a relieved smile on his face.

The old man said: "Lin Feng, now that you have passed this test, your path to immortality will be brighter." Lin Feng and Li'er smiled at each other. They knew that the road ahead was still long, but they were ready to face the challenge.
