Genshin Impact.

Under the guidance of the old man, Lin Feng and Li Er descended to the mortal world to experience the tribulations. They arrived in a world full of mystery and unknown.

When they first arrived in the mortal world, Lin Feng and Li Er were surprised by everything around them. But soon, they found that this place was not as beautiful as they had imagined. The suffering, disputes and desires of the world shocked and confused them.

In a prosperous town, Lin Feng and Li'er met a poor beggar. He was ragged, haggard, and his eyes were full of despair. Li'er felt pity for him and wanted to help him. However, when she took out some money, she attracted the covetousness of a group of hooligans.

"Little girl, you are so rich, why don't you share some with us!" the thugs said viciously.

Lin Feng stepped forward and started a fierce fight with the ruffians. In the end, with his extraordinary power, he defeated the ruffians.

"Lin Feng, it seems that the world is not peaceful either." Li'er said worriedly.

Lin Feng nodded: "But this is also part of our tribulation, we must face it."

They continued walking and came to an ancient temple. In the temple, a mysterious old man was explaining Buddhism to everyone. Lin Feng and Li'er were attracted by the old man's words and listened quietly.

The old man suddenly looked at them, with a strange light flashing in his eyes: "Two donors, are you from the Immortal Sect?"

Lin Feng and Li'er were shocked and didn't know how to answer.

The old man smiled and said, "Don't panic. I can see the aura of immortality in you. But in this mortal world, immortality is not necessarily a good thing."

Lin Feng bowed and asked, "Please give me some advice, old man."

The old man said slowly: "The mortal world has its own rules. Although immortal power is strong, it will backfire if abused. You need to feel the emotions of the mortal world with your heart and understand the true meaning of life before you can complete the tribulation."

Lin Feng and Li'er nodded thoughtfully.

After leaving the temple, they met a kind merchant who invited them to go to a distant city to do business. During the journey, Lin Feng and Li'er witnessed the merchant's wisdom and courage, and also felt the warmth and kindness of the world.

However, when they arrived in the city, they found that the merchant had been framed by his competitors and was in trouble.

Lin Feng and Li'er decided to help the merchant. They used their wisdom and magical powers and finally helped the merchant out of his predicament.

"Thank you, if it weren't for you, I would have gone bankrupt." said the businessman with tears of gratitude.

Lin Feng and Li'er smiled at each other: "You're welcome. This is what we should do."

After this period of experience, Lin Feng and Li Er have a deeper understanding of life in the mortal world. But their journey of tribulation is far from over.

By chance, Lin Feng and Li Er learned a legend about a mysterious treasure. It is said that the secret to becoming an immortal is hidden in the treasure.

"Lin Feng, should we go look for this treasure?" Li'er asked.

Lin Feng pondered for a moment: "Since it is a tribulation, let's go and take a look. But be careful, there may be great danger hidden in it."

So, they embarked on a journey to find the treasure. Along the way, they encountered many difficulties and tests, including ferocious beasts, complex mechanisms, and various mysterious magic traps.

But Lin Feng and Li'er never gave up. With firm belief and mutual support, they gradually approached the location of the treasure.

However, when they finally found the treasure, they discovered it was all a hoax.

"Damn it, we were deceived!" Li'er said angrily.

Lin Feng said calmly: "Don't worry, maybe this is also a test for us."

Just as they were about to leave, they were suddenly enveloped by a powerful force and a dark figure appeared in front of them.

"Do you think this is the end? You are too naive!" the black shadow sneered.

Lin Feng and Li Er are ready for battle. A fierce battle is about to begin...
