Genshin Impact.

After going through many tests and successfully breaking through, Lin Feng and Li Er embarked on a new journey. This time, they came to the mortal world to experience the tribulation, shouldering the mission of exploring the truth of the human world and honing their Tao heart.

The two landed in a bustling town, with people coming and going in the streets and alleys, shouting and playing mixed together. Lin Feng and Li'er looked around curiously, full of desire to explore this new world.

They were walking in the town when they heard a commotion. It turned out that a group of people were gathered in front of a mansion, pointing and talking. Lin Feng and Li Er got closer and saw that the door of the mansion was closed, but there were bursts of crying and quarreling coming from inside.

Out of curiosity, Lin Feng went up to an old man and asked him. The old man stroked his beard and sighed, "The owner of this mansion is a wealthy businessman in the city. Recently, strange things have happened frequently in his home. There are strange noises every night, and the family's property has disappeared inexplicably. Now everyone is in a panic."

Lin Feng and Li Er looked at each other and decided to help this family solve their problem. They knocked on the door of the mansion, and when the rich businessman heard their intention, he welcomed them into the house as if they had grabbed a life-saving straw.

After entering the mansion, Lin Feng and Li'er began to investigate carefully. With her keen perception, Li'er discovered some subtle fluctuations in magic power. "It seems that this is not the work of ordinary thieves. There must be evil spirits at work." Li'er said softly.

As night fell, a strange atmosphere filled the mansion. Lin Feng and Li'er hid their bodies and stayed in the dark. At midnight, a black shadow flashed by and headed towards the warehouse. Lin Feng and Li'er quickly followed and saw the black shadow rummaging around in the warehouse.

Lin Feng cast a spell to freeze the shadow in place. When the lights came on, they could see clearly that the shadow was actually a fox demon. A trace of panic flashed in the fox demon's eyes, "Who are you? How dare you ruin my good deeds!"

Lin Feng asked sternly, "Why are you causing trouble here?" The fox demon snorted coldly, "This rich businessman is rich and cruel, and oppresses the people. I am just enforcing justice for the people."

Lin Feng and Li Er decided to investigate the truth of the matter first, and they visited the people in the city. After some understanding, they found that although the rich businessman was a little shrewd in business, he was not as bad as the fox demon said.

It turned out that the fox demon had a conflict with the rich businessman and held a grudge against him, so he deliberately caused trouble. Lin Feng and Li'er explained to the fox demon with reason and moved him with emotion, "Even if he is at fault, it should be judged by human laws. You use demon magic to do evil, which will only put yourself in an irreparable situation."

After hearing this, the fox demon fell into deep thought and finally realized his mistake. He decided to make up for his mistake and used his magic power to help the rich businessman find his lost property and apologize to him.

After solving the problem of the rich businessman's house, Lin Feng and Li'er continued to travel in the city. In a teahouse, they heard a legend about a mysterious treasure. It is said that in a valley outside the city, there are endless treasures and peerless magic weapons, but there is a powerful formation guarding it, and countless treasure hunters have never returned.

Lin Feng and Li Er became very interested in this legend and decided to go to the valley to find out. They walked along the rugged mountain road and finally arrived at the legendary valley. The valley entrance was filled with thick fog, which faintly revealed a dangerous atmosphere.

The two of them stepped into the valley carefully. As soon as they entered, they triggered the formation. The surrounding scene changed instantly, and countless phantoms rushed towards them. Lin Feng and Li'er used their magic to start a fierce battle with the phantoms.

During the battle, they gradually discovered the flaws in the formation and successfully cracked it. However, what awaited them was not treasure, but an old man trapped here.

When the old man saw them, a hint of surprise flashed in his eyes, "I have been trapped here for hundreds of years, and today I finally met the destined person." It turned out that the old man was a senior cultivator who had eaten a poisonous fruit by mistake, causing him to lose all his magic power and be trapped in the valley.

Lin Feng and Li Er decided to help the old man detoxify. They searched for herbs everywhere and used magic to refine elixirs. After several days of hard work, they finally refined an antidote and helped the old man restore his magic power.

In order to repay them for saving his life, the old man decided to teach them a unique magic. Lin Feng and Li Er studied hard, and their attainments in the magic were greatly improved.

In the experience of the world, Lin Feng and Li Er continue to grow, and their Taoism hearts become more determined. However, what they don't know is that a greater crisis is quietly approaching...
