Genshin Impact.

Lin Feng stood on the vast land, his heart full of confusion and determination about the future. Li'er quietly accompanied him, her eyes full of concern and trust.

They had just gone through a difficult decision, and Lin Feng decided to embark on this unknown immortal journey. At this moment, there was a mysterious fog in front of them, as if hiding countless challenges and opportunities.

The old man appeared in front of them with an unfathomable smile on his face. "Lin Feng, the journey to immortality is full of difficulties and obstacles. You must be prepared."

Lin Feng nodded solemnly, "Senior, I have made up my mind. No matter what difficulties lie ahead, I will not back down."

Li'er held Lin Feng's hand tightly, "Brother Lin Feng, I will always be with you."

The three of them stepped into the mist together. The surrounding scene began to become distorted, and strange sounds came from all directions. Lin Feng observed the surroundings vigilantly, and the fairy sword in his hand flashed with light.

Suddenly, a group of strange-looking monsters rushed out of the mist and pounced on them with their fangs and claws bared. Lin Feng was not afraid at all, and wielded his magic sword to start a fierce battle with the monsters. Li Er cast a spell on the side to provide support for Lin Feng.

After a hard fight, they finally repelled the monster. But before they could catch their breath, they were trapped in a mysterious formation. The light in the formation was flashing, and the strong pressure made it almost impossible for them to move.

Lin Feng tried his best to circulate the immortal power in his body, trying to find the flaws in the formation. The old man instructed him: "Lin Feng, feel the rhythm of the formation carefully and find the key."

Lin Feng closed his eyes, calmed down, and finally found a flaw in the formation. He concentrated his strength and broke through the formation in one fell swoop.

However, their troubles were not over. A turbulent river appeared in front of them, and a strange atmosphere filled the river. Lin Feng looked at the river and had a bad premonition in his heart.

"There may be huge danger hidden in this river." Li'er said worriedly.

Lin Feng took a deep breath, "But we have no choice but to cross the river."

They stepped into the river carefully, and the water instantly became icy cold. Suddenly, huge tentacles stretched out from the bottom of the river and attacked them. Lin Feng fought hard, but the tentacles became more and more, gradually putting them in trouble.

At this moment, the immortal power in Lin Feng's body suddenly burst out, and a ray of light flashed, repelling all the tentacles. They took the opportunity to swim to the other side.

After landing, they found themselves in an ancient ruins. The ruins were filled with powerful immortal power fluctuations, which shocked people.

Lin Feng curiously explored the ruins and found a mysterious stone tablet. There were some ancient characters engraved on the stone tablet, and Lin Feng tried hard to identify them.

"This seems to be an ancient secret book of immortality." said the old man.

Lin Feng carefully comprehended the contents on the stone tablet, and gradually, powerful fluctuations of immortal energy emanated from his body.

Just when he was about to comprehend the immortal law, a group of mysterious figures appeared in the ruins. These figures exuded an evil aura and obviously had bad intentions.

"Lin Feng, be careful!" Li'er exclaimed.

Lin Feng opened his eyes, facing these mysterious enemies, he did not flinch. A fierce battle broke out again...

After a fierce battle, Lin Feng and his companions finally defeated the mysterious figure, but they also consumed a lot of immortal power and were exhausted.

Just as they were about to rest, a strong wave came from the depths of the ruins. Lin Feng's heart tightened, and his intuition told him that there was something more important there.

They supported each other and walked towards the source of the fluctuations, where they found a mysterious treasure chest surrounded by powerful restrictions.

Lin Feng once again used his immortal power to try to break the restriction. After many attempts, he finally opened the treasure chest. A dazzling light emanated from the treasure chest, and an ancient immortal book appeared in front of them.

Lin Feng picked up the Immortal Book and felt the powerful force contained in it. However, at this moment, a strong suction force drew them into an unknown space.

In this space, time and space became distorted. Lin Feng tried hard to stay awake and tried to find a way out.

"Lin Feng, don't give up, we will definitely find a way out." Li'er's voice sounded in his ears.

Lin Feng nodded. With his strong will and persistence in the path of immortality, he finally found the flaw in the space and successfully escaped with Li'er and the old man.

When they returned to the real world, they found themselves at the foot of a fairy mountain, which was shrouded in clouds and mist and filled with fairy music.

Lin Feng looked at the top of the mountain, his heart full of anticipation. "This may be the new starting point of our immortal journey."

They set out on the mountain climbing journey, heading towards a higher path to immortality...
