Genshin Impact.

Under the guidance of the old man, Lin Feng and Li Er embarked on the journey to the mortal world. Amidst the clouds and mist, their figures gradually disappeared into the sky and headed towards the human world.

In the human world, in a prosperous town, Lin Feng, Li'er and the old man transformed into ordinary mortals and blended into the bustling crowd. Lin Feng was dressed in a green shirt, with a handsome face and a smart and resolute look in his eyes; Li'er was dressed in a light pink silk skirt, with skin as white as snow and eyes as bright as stars, and she exuded a smart aura in her every move; the old man was dressed in a simple gray robe, with white hair, but he was energetic.

They temporarily settled in the town, looking for an opportunity to survive. One day, Lin Feng and Li'er were wandering the streets and accidentally found a wall with a notice posted on it. The notice said that a ferocious monster had appeared in the forest outside the city recently, often attacking passers-by and caravans. The city lord offered a reward for a capable person to go and exorcise the monster.

A gleam of light flashed in Lin Feng's eyes. He turned to look at Li'er and the old man and said, "This may be the first challenge in our journey." Li'er nodded without any fear in her eyes. The old man stroked his beard and smiled in agreement.

The three of them immediately decided to go to the forest outside the city. After entering the forest, there was a gloomy atmosphere all around, with towering trees and intertwined branches and leaves, blocking out the sun. Lin Feng carefully explored the way ahead, Li'er followed closely behind, and the old man walked slowly, always paying attention to the movements around him.

Suddenly, a gust of wind whistled past, and a huge monster rushed out of the woods. It was shaped like a tiger, but had a pair of huge wings, its fur was flashing with a strange light, and flames were spewing from its mouth.

Lin Feng was not afraid at all. A flash of light appeared in his hand, and a long sword appeared. He flew towards the monster. Li'er also cast a spell, shooting ice arrows at the monster. The old man cast defensive spells for them and observed the monster's weaknesses.

The monster felt threatened and attacked them even more frantically. It flapped its wings, creating a gust of wind that blew Lin Feng and Li'er all over the place. Lin Feng steadied himself and attacked the monster with his sword skills like a gust of wind and rain, leaving sword marks on the monster's body. Li'er's ice arrows also kept hitting the monster, causing the monster's movements to gradually become slower.

With the tacit cooperation of the three, the monster gradually lost the upper hand. Finally, Lin Feng found the weakness of the monster and stabbed it in the vital part with a sword. The monster screamed, fell to the ground, and turned into a cloud of smoke and disappeared.

After dealing with the monster, they continued to move forward in the forest. Soon after, they found an ancient temple. Although the temple was dilapidated, it exuded a mysterious atmosphere. Lin Feng opened the door and walked into the temple, only to see an unknown statue enshrined in the temple.

The eyes of the statue flashed with strange light, as if watching them. Li'er felt uneasy. She pulled the corner of Lin Feng's clothes and said, "Brother Lin Feng, I think there is something wrong with this temple." Lin Feng nodded, and he also felt something strange.

At this moment, the statue suddenly moved, stretched out its hands, and rushed towards them. The old man shouted, "Be careful!" and then cast a powerful spell and started a fierce battle with the statue.

Lin Feng and Li Er also used their unique skills to help the old man fight against the statue. With their joint efforts, the statue gradually lost its power and was finally defeated by them. The statue turned into a pile of rubble, and peace returned to the temple.

However, their troubles did not end there. After leaving the temple, they encountered a group of mysterious men in black. Without saying a word, the men in black attacked them. Lin Feng and others fought back and started a desperate fight with the men in black.

During the battle, Lin Feng discovered that these men in black had impressive strength, and their moves were very strange, as if they had some special purpose. After a fierce battle, they finally repelled the men in black, but they also suffered some injuries.

The old man looked at the injured Lin Feng and Li Er, his heart full of worry. He said: "It seems that this trip to the mortal world is much more difficult than we thought. We must be more cautious." Lin Feng and Li Er nodded, their eyes full of determination.

They found a safe place in the forest to rest and heal. During the healing process, Lin Feng fell into deep thought. He knew that this journey to the mortal world was full of unknown dangers, but he also believed that as long as they united, they would be able to overcome the difficulties and complete the journey.

After a period of recuperation, their injuries were basically healed. At this time, they received a mysterious letter. The letter invited them to a place called "Xianling Valley", which was said to hide important clues about their tribulations.

Lin Feng, Li Er and the old man did not hesitate and immediately set off for the Fairy Valley. The Fairy Valley was located deep in the forest, surrounded by mountains and filled with clouds and mist. They walked into the Fairy Valley along a winding path.

The valley was beautiful, with exotic flowers and plants everywhere, and a clear stream flowing through it. However, they were not attracted by the beautiful scenery, but instead watched the surroundings vigilantly.

Suddenly, a figure flashed before their eyes. Lin Feng immediately chased after it, only to see that figure stop in front of a cave. The figure turned around and turned out to be a young woman. The woman had a beautiful face and a cunning look in her eyes.

The woman looked at them and said with a smile: "Welcome to the Fairy Valley. I have been waiting for you for a long time." Lin Feng asked: "Who are you? Why did you lead us here?" The woman smiled and said: "My name is Ling'er, and I am the guardian of this Fairy Valley. I know that you are immortals who have come down to earth to experience tribulations. I can help you complete the tribulations."

Lin Feng and the others followed Ling'er into the cave half-believingly. The cave was filled with a mysterious atmosphere, and strange lights flickered on the walls. Ling'er pointed to a stone tablet deep in the cave and said, "The secret of your tribulation is recorded on that stone tablet. As long as you solve the puzzle on the stone tablet, you can find the way to tribulation."

Lin Feng and others walked to the stone tablet and saw some strange symbols and patterns engraved on it. They began to study these symbols and patterns carefully, trying to solve the puzzle. After some effort, they finally solved the puzzle on the stone tablet.

A flash of light appeared on the stone tablet, and a line of words appeared: "The road to overcoming tribulations lies in the heart. Where the heart leads, the path to immortality will be achieved." Lin Feng and others fell into deep thought, and they began to think about the meaning of this sentence.

At this moment, the cave began to shake violently, and cracks appeared on the surrounding walls. Ling'er shouted, "Oh no, the cave is going to collapse, let's get out!"

They quickly ran out of the cave. However, the moment they ran out of the cave, a powerful force dragged them into a mysterious space. In this space, they saw their past, present and future, as well as the hardships and challenges they had experienced.

Lin Feng looked at Li'er and the old man and said firmly: "No matter how many difficulties there are ahead, we must go on together." Li'er and the old man nodded, they held hands tightly together, and began a new journey...
