Genshin Impact.

Under the guidance of the old man, Lin Feng and Li'er came down to earth to experience hardships and difficulties, just to seek the opportunity to break through to the immortal path.

In a dark valley, Lin Feng was observing his surroundings with vigilance. The wind was howling, as if hiding countless dangers. Li'er followed closely behind him, holding the immortal sword tightly in her hand, with a determined look in her eyes.

"Brother Feng, this place is too gloomy. I always feel like something is secretly watching us." Li'er said softly.

Lin Feng nodded slightly, "Be careful, this tribulation won't be easy."

Suddenly, a strong wind blew up, and sand and stones filled the sky. A huge monster rushed out from the depths of the valley, its body as big as a mountain, and its eyes were bloodshot.

Lin Feng and Li'er instantly entered combat mode. Lin Feng used his magic, his hands flashed with light, and amulets flew towards the monster. Li'er then waved her magic sword, the sword energy was like a rainbow, and she cooperated with Lin Feng tacitly.

However, this monster was powerful, with thick skin and flesh, and the magic and sword energy caused little damage to it. It swung its tail violently, and Lin Feng was unable to dodge and was hit hard and flew out.

"Brother Feng!" Li'er exclaimed and rushed towards Lin Feng desperately.

Lin Feng struggled to get up from the ground, with a trace of blood flowing from the corner of his mouth, "I'm fine, keep fighting!"

The two teamed up again and fought a desperate battle with the monster. After a hard fight, they finally found the monster's weakness and successfully defeated it.

"It's not advisable to stay here for long, let's leave quickly." Lin Feng said.

The two continued walking and came to an ancient town. There was a strange atmosphere in the town and the streets were empty.

"This town is too quiet, something is wrong." Li'er said.

At this moment, a group of dark shadows came from all directions. They turned out to be a group of demonized villagers.

Lin Feng and Li'er did not flinch, and once again used their magic to fight these demonized villagers. During the fierce battle, Lin Feng discovered that the power of these demonized villagers was endless, as if they were controlled by some powerful magic.

"Lier, we must find the source of their control, otherwise it will be difficult to win." Lin Feng said.

After some searching, they finally found a demon temple hidden deep in the town.

In the devil's palace, an evil wizard is manipulating magic power.

"So it's you who's causing all this trouble!" Lin Feng shouted angrily.

The wizard sneered, "You are courting death, so don't blame me for being rude!"

A fierce battle between immortals and demons began. Lin Feng and Li'er used all their skills to fight the wizard to the death.

The wizard's magic was powerful and strange, and it pushed Lin Feng and Li'er into desperate situations again and again. But they relied on their firm belief and tenacious will and never gave up.

At the critical moment, Lin Feng realized a new magic, and his power exploded instantly. Li'er also broke through her own limit, and the two joined hands to finally defeat the wizard and rescue the villagers in the town.

However, their journey was far from over. On the following journey, they encountered various powerful enemies and difficult tests.

In a mysterious forest, they encountered a group of elves who were good at illusions. These elves could create realistic illusions that could make people lost in them.

Lin Feng and Li'er fell into an illusion, and they saw the things they feared most. Lin Feng saw his relatives and friends being hurt, and Li'er saw Lin Feng leaving her.

"These are all illusions, we can't be fooled!" Lin Feng shouted loudly.

The two tried hard to stay awake, and relying on their trust in each other and their persistence in the path to immortality, they finally broke through the illusion.

After walking out of the forest, they came to the foot of a towering mountain. The mountain was shrouded in clouds and mist. According to legend, there was a mysterious book of immortal arts on the top of the mountain, and obtaining it would greatly improve one's cultivation.

Lin Feng and Li Er started to climb the mountain without hesitation. The mountain road was rugged, steep and difficult to walk on, and there were various traps and obstacles.

During the climb, Li'er accidentally stepped on a trap and fell down instantly. Lin Feng was quick to grab Li'er.

"Lier, hold on to me!" Lin Feng shouted loudly.

Li'er held Lin Feng's hand tightly, and with Lin Feng's help, she finally escaped from danger.

After much hardship, they finally reached the top of the mountain, but what was waiting for them was a powerful guardian immortal.

"If you want to get the secret book, you have to get past me first!" said the guardian immortal.

Lin Feng and Li'er looked at each other and said firmly: "We are not afraid of challenges!"

A fierce battle broke out again. The magic of the guardian immortal was unfathomable, and Lin Feng and Li'er fell into trouble many times, but they never gave up and stood up from failure again and again.

Finally, with their unremitting efforts, the guardian immortal recognized their strength and determination and handed over the secret book to them.

Lin Feng and Li Er took the secret book and continued on their journey to immortality. They knew that there were more challenges and tests waiting for them, but they were ready. No matter what difficulties they encountered, they would keep going until they rose from the ashes and achieved immortality.
