Genshin Impact.

After going through many tests, Lin Feng, Li'er and the old man finally ushered in a new stage of descending to the mortal world to experience trials.

Lin Feng stood on the clouds, overlooking the world below, his heart full of emotion. Li'er stood quietly beside him, her eyes revealing determination and expectation. The old man stroked his beard and said, "This time I come to the world to experience the tribulations, I must go through many hardships before I can achieve the right result."

The three of them transformed into three rays of light and plunged into the mortal world.

They landed in a prosperous town, with a bustling crowd and hawking sounds. Lin Feng quickly adapted to the surrounding environment and took Li'er and the old man to travel around the town. However, they soon discovered that although the people here seemed to live a peaceful life, they were hiding unknown crises.

In the corner of the town, a dark organization is quietly rising. They use evil magic to control innocent people and make huge profits. Lin Feng accidentally discovered the evil deeds of this organization, and the fire of justice ignited in his heart.

"Lier, old man, we can't just sit there and watch." Lin Feng said.

Li'er nodded, and the old man reminded her: "Be careful, there may be a bigger conspiracy behind this."

Lin Feng decided to investigate this dark organization in depth. They disguised themselves as ordinary people and sneaked into the organization's activities. After some investigation, they found that the leader of this organization was actually a master of evil magic, whose magic was powerful and strange.

During a secret operation, Lin Feng accidentally exposed his identity, triggering a fierce battle. Members of the dark organization cast various evil spells to attack Lin Feng and his team. Lin Feng relied on his superb magic to resolve crises time and time again. Li Er also used her unique skills to provide support for Lin Feng.

The old man was observing the situation from the side, giving instructions from time to time. "Lin Feng, pay attention to his magic flaws!" the old man shouted.

Hearing this, Lin Feng seized the opportunity and defeated several powerful enemies in one fell swoop. However, the enemies continued to pour in, and the situation became more and more critical.

Just when they were about to collapse, a mysterious light descended from the sky. In the light, a mysterious immortal appeared. The immortal waved his sleeves and instantly subdued the members of the dark organization.

"Thank you for your help, immortal." Lin Feng said gratefully.

The immortal smiled and said, "I will help you in your righteous actions. But the darkness in this world is far more than this, so you need to be careful." After that, the immortal disappeared.

Lin Feng and his companions continued to move forward in the mortal world, helping many suffering people along the way. However, their actions attracted the attention of other forces.

A mysterious organization called "Shadow Pavilion" began to secretly follow them, trying to find an opportunity to eradicate them. Lin Feng sensed the danger and discussed countermeasures with Li'er and the old man.

"We can't just passively defend all the time. We must take the initiative and find the weakness of this Shadow Pavilion." Lin Feng said.

Li'er agreed: "But we must be careful not to fall into their trap."

The old man pondered for a moment and said, "I do have a plan..."

According to the old man's plan, they deliberately exposed their flaws in a remote place to lure the Shadow Pavilion's people into the trap. Sure enough, the assassins of the Shadow Pavilion showed up one after another. Lin Feng and his men were well prepared and started a desperate fight with the assassins.

During the battle, Lin Feng discovered that the assassins of Shadow Pavilion were all controlled by a special poison and lost their self-awareness. He felt pity and decided to find an antidote to save these assassins.

After some efforts, they finally found the formula of the poison and the method of making the antidote. Lin Feng personally refined the antidote and saved many assassins. After regaining consciousness, these assassins were grateful to Lin Feng and his team and expressed their willingness to help them fight against the Shadow Pavilion.

With the help of the killers, Lin Feng and his team gradually figured out the details of the Shadow Pavilion. It turned out that there was a powerful mastermind behind the Shadow Pavilion, who had been manipulating everything.

In order to completely eradicate the Shadow Pavilion, Lin Feng and his team decided to go straight to Huanglong and have a final showdown with the mastermind behind the scenes. In a gloomy castle, they finally saw the mastermind behind the scenes.

The mastermind sneered, "Do you think you can defeat me? You are too naive!"

Lin Feng was not afraid at all and said: "Justice will eventually defeat evil, and today is your end!"

A world-shaking battle begins. Lin Feng, Li'er and the old man work together to fight the mastermind behind the scenes.

The battle lasted for a long time, and both sides were seriously injured. But Lin Feng and his men never gave up, and gradually gained the upper hand with their firm belief and tenacious will.

In the end, Lin Feng used his most powerful magic to defeat the mastermind behind the scenes and save the world.

The sun shone on them, and Lin Feng, Li'er and the old man smiled at each other. They knew that although the immortal road was long, as long as there was justice and faith in their hearts, they would surely be able to move towards glory.
