Genshin Impact.

Under the guidance of the old man, Lin Feng and Li Er went down to the mortal world to experience the tribulations. They were in the bustling and lively world, and everything around them was both strange and novel to them.

Lin Feng looked at the bustling crowd, feeling a lot of emotion in his heart. He knew that this trip to the mortal world was not easy, but he also firmly believed that this was a necessary test for them during their cultivation. Li Er seemed a little nervous and followed Lin Feng closely.

They came to a small town where there was a rumor that there was a mysterious place where strange lights would flash every full moon night. Lin Feng and Li'er decided to go there to explore on a full moon night.

On a full-moon night, they came to the legendary place. They saw a beam of light rising from the ground, illuminating the entire night sky. Lin Feng and Li'er were attracted by this strange scene and couldn't help but approach it.

However, when they approached the aura, they were drawn into it by a powerful force. When they opened their eyes again, they found themselves in an unfamiliar space.

The space was filled with a mysterious atmosphere, and the walls were covered with ancient runes. Lin Feng tried to decipher these runes, but found that they contained profound mysteries. Li Er carefully observed the surrounding environment, feeling uneasy.

At this moment, a deep voice came from the space: "Intruders, you must pass the test before you can leave this place."

As soon as the words fell, a series of light and shadows attacked them. Lin Feng and Li Er quickly used their magic to resist. After a fierce battle, they finally repelled the light and shadows.

Just as they breathed a sigh of relief, the space suddenly began to distort, and countless passages appeared. Each passage exuded a different aura, making it difficult to choose.

Lin Feng pondered for a moment and said, "Lier, let's go our separate ways and find our own exits." Although Lier was a little reluctant, she still nodded.

Lin Feng walked into a passage full of flames. The flames in the passage were burning fiercely and extremely hot. He gritted his teeth, used immortal magic to protect himself, and moved forward step by step.

Li'er chose a passage filled with frost. The cold air made her shiver, but she kept moving forward with her strong will.

In the passage, Lin Feng encountered various traps and obstacles. Sometimes it was a huge rock that suddenly appeared, and sometimes it was a sharp blade hidden in the flames. But he never gave up, thinking in his heart that he must find the exit and reunite with Li'er.

Li'er was facing the same dilemma. The monsters in the frost kept attacking her, and she fought hard, suffering multiple injuries.

After a long time, Lin Feng finally walked out of the passage. He found himself in a peaceful valley full of exotic flowers. While he was admiring the beautiful scenery, he suddenly heard Li'er's cry for help.

Lin Feng ran towards the direction of the sound without hesitation. He saw Li'er trapped by a huge monster and unable to escape.

Lin Feng roared angrily and used his powerful magic to fight a life-and-death battle with the monster. In the end, with Lin Feng's efforts, the monster was defeated and Li'er was saved.

The two hugged each other and cried, thankful that they were still alive.

At this moment, the space changed again, and they were transported to an ancient palace. In the palace were placed various precious magic weapons and secret books.

Lin Feng and Li'er were very excited, but they soon discovered that these magic weapons and secret books were sealed by powerful restrictions and could not be easily obtained.

They began to look for a way to lift the ban. In the corner of the palace, Lin Feng found a stone tablet with words engraved on it. After careful study, they finally understood the key to lifting the ban.

After some efforts, they successfully lifted the ban and obtained magic weapons and secret books.

Just as they were about to leave the palace, a mysterious old man appeared. The old man looked at them with a hint of admiration in his eyes: "You have passed the test, and these magic weapons and secret books are your rewards. But you must remember that the road to immortality is long, and there are more challenges waiting for you."

Lin Feng and Li'er thanked the old man and left this mysterious space with the magic weapons and secret books.

After returning to the mortal world, they found that their state of mind had greatly improved. However, they also knew that this was just a small episode in their immortal journey, and there would be more difficulties and tests waiting for them in the future.

They continued to move forward, gaining experience in the world, and constantly improving their cultivation and state of mind.

By chance, Lin Feng and Li Er met a little girl with a miserable life. The little girl was seriously ill and had no money to treat her. Lin Feng and Li Er felt pity for her and decided to help her.

They used the magic and medical skills they had learned to treat the little girl. After several days of hard work, the little girl finally recovered. The little girl's family was grateful to them.

This incident made Lin Feng and Li'er feel the joy of helping others, and also made them more determined to uphold kindness and justice on their journey to immortality.

However, their good deeds attracted the attention of a local evil force, which was jealous of Lin Feng and Li'er's abilities and decided to attack them.

One night, the evil forces sent assassins to attack Lin Feng and Li Er. Fortunately, they were well prepared and had a fierce battle with the assassins.

In the battle, Lin Feng and Li Er gradually gained the upper hand. The killers saw that the situation was not good and wanted to escape. Lin Feng and Li Er chased them relentlessly and finally subdued all the killers.

After this incident, Lin Feng and Li Er's reputation spread throughout the local area, and people were full of admiration and gratitude for them.

As time goes by, Lin Feng and Li Er's experience in the world becomes richer and richer. They encounter all kinds of people and things, including kind people and evil demons.

In a battle with demons, Lin Feng and Li Er were unfortunately seriously injured. They fled to a deep mountain to find a way to heal their wounds.

In the mountains, they met a hermit immortal, who saw that they were kind-hearted and taught them a unique healing method.

After a period of training, Lin Feng and Li Er finally recovered from their injuries. They were grateful for the help of the immortals and continued on their journey to immortality.

During the days of training in the mortal world, the relationship between Lin Feng and Li Er became deeper and deeper. They supported each other and faced the various difficulties on the immortal journey together.

However, their immortal journey was not smooth sailing. Once, they were accidentally involved in a dispute between martial arts sects.

The two sects fought each other for territory and resources, and the people suffered. Lin Feng and Li Er decided to step forward and mediate the dispute.

They visited the leaders of the two sects respectively, and persuaded them with reason and emotion. After many efforts, the two sects finally decided to put aside their hatred and coexist peacefully.

The people praised Lin Feng and Li'er's righteous deeds, and their names became famous in the world.

But Lin Feng and Li'er did not become proud and complacent because they knew that their mission was not yet complete and they continued to pursue a higher path to immortality in the mortal world.

In another adventure, they discovered an evil organization hidden in the mountains, which attempted to use dark forces to rule the world.

Lin Feng and Li Er decided to destroy the organization and save the people. They went deep into the tiger's den and launched a thrilling decisive battle with the evil organization.

During the battle, Lin Feng and Li Er encountered unprecedented powerful enemies, but they relied on their firm belief and tacit cooperation to overcome dangers again and again.

In the end, they successfully defeated the leader of the evil organization and destroyed the source of the dark power.

People in the world are grateful to them and regard them as heroes.

Lin Feng and Li Er continue to grow and break through themselves in their earthly experiences. Their immortal path becomes brighter and brighter, and their story continues...
