Genshin Impact.

Lin Feng, Li Er and the old man went down to the mortal world together to experience the tribulations. After falling into the mortal world, they found that this world was very different from the fairy world. The atmosphere of fireworks was filled with people coming and going in the streets and alleys, and the sounds of shouting, talking and laughing were intertwined.

"Master, where exactly are the opportunities in this mortal world and how can we find them?" Lin Feng looked at the bustling crowd with a hint of confusion in his eyes.

The old man stroked his beard and looked into the distance with deep eyes: "Opportunities cannot be forced. We need to feel with our hearts and use our eyes to see through every detail of this world. Perhaps, inadvertently, opportunities will come."

Li'er blinked her bright eyes and said, "We can't just run around without any clues, how about we start from this town and explore it?"

Lin Feng nodded: "Li'er is right. This town is crowded with people and things going on. Maybe we can get some useful clues."

So the three of them began to travel through the town. They walked through every shop and talked to all kinds of people. However, after several days, they still did not find any clues related to chance.

One day, Lin Feng and the other two came to a temple. Although the temple was not big, it was very popular and there were many believers.

"Master, this temple may have something special. Why don't we go in and take a look?" Lin Feng suggested.

The old man nodded slightly, and the three of them walked into the temple. Inside the temple, a solemn and majestic Buddha statue stood in the center of the hall, and incense was curling from the incense burner in front of the Buddha statue.

As they were observing carefully, an old monk came over. He put his hands together and bowed to them: "Amitabha, the three donors are unfamiliar to me. I wonder what brings you here?"

The old man responded, "Master, the three of us, the master and the disciples, have come down to earth to experience trials and tribulations. We are looking for opportunities in the mortal world. I wonder if you could give us some pointers?"

The old monk smiled and said, "Opportunities are determined by heaven and cannot be forced. However, since the three donors have met this poor monk, it is also a kind of fate. Recently, strange things have been happening in the Black Wind Mountain outside the city. Perhaps that is where the three donors' opportunities lie."

Lin Feng and the other two thanked the old monk, left the temple, and headed towards Black Wind Mountain.

Black Wind Mountain is steep and has towering trees. There is a strange atmosphere in the mountain that makes people shudder.

The three of them walked into the mountain cautiously, hearing the eerie sound of wind and the roar of unknown beasts from time to time. Suddenly, a huge python jumped out of the woods and pounced on them with its bloody mouth wide open.

Lin Feng was not afraid at all, and drew his sword to meet the attack. Li'er also cast a spell, and beams of light shot towards the python. The old man stood by to help them, giving them some pointers from time to time.

With the concerted efforts of the three, they finally killed the python. However, before they had time to catch their breath, a group of monsters appeared around them. These monsters had different shapes, some had green faces and fangs, and some were covered in flames.

"It seems that the Black Wind Mountain is indeed not simple. Everyone, be careful!" the old man said loudly.

Lin Feng and Li Er huddled together and fought a fierce battle with the monsters. Their bodies were covered in blood, both from the enemy and their own.

After an unknown amount of time, the monsters were finally wiped out. The three of them were exhausted, but they did not dare to stop and continued to walk deeper into the mountain.

In a valley, they found a mysterious cave. There was a strange light flickering at the entrance of the cave, as if calling them.

"Master, this cave might contain the opportunity we are looking for." Lin Feng said.

The old man pondered for a moment and nodded: "It's better to be cautious. Let's go in and take a look."

Walking into the cave, there was a pungent smell, a faint blue light flickered on the walls, and the ground was covered with strange-shaped stones.

They walked forward cautiously, and suddenly, a powerful formation light lit up, trapping them inside.

"Oh no, it's a trap!" Li'er exclaimed.

The old man looked solemn: "Don't panic, calm down and find a way to break the formation."

The three began to study the formation carefully, and after some effort, they finally found the flaw in the formation. Just as they were about to break out of the formation, a mysterious figure appeared in front of them.

"Haha, I've been waiting for you for a long time!" the mysterious man sneered.

Lin Feng glared at the mysterious man: "Who are you? Why did you set a trap here?"

The mysterious man smiled and said, "It doesn't matter who I am. What matters is that your opportunity will be in my pocket!"

After that, the mysterious man launched an attack on them. The old man stepped forward and started a fierce duel with the mysterious man. Lin Feng and Li'er were not to be outdone and cast their strongest spells.

The four of them fought a thrilling battle in the cave. For a moment, light flashed, spells flew, and the entire cave trembled in the aftermath of their battle.

After a hard fight, Lin Feng and the other two finally teamed up to defeat the mysterious man. However, they were also seriously injured.

Just when they thought everything was over, a powerful suction force came from deep in the cave, sucking them into an unknown space.

In this space, there was chaos all around, with no visible boundaries. Lin Feng and the other two were suspended in the air, at a loss.

"Master, what's going on?" Li'er asked in horror.

The old man frowned and said, "This place is very strange. I'm afraid we are in a new crisis. However, since we have come to this point, we can only act according to circumstances."

At this moment, a ray of light appeared from the chaos, and gradually condensed into a huge ball of light. In the ball of light, some mysterious runes and patterns could be vaguely seen.

Lin Feng approached the ball of light curiously, and when his hand touched the ball of light, a strong force surged into his body. His body trembled involuntarily, and a painful expression appeared on his face.

"Lin Feng!" Li'er exclaimed and wanted to go forward to help, but was stopped by the old man.

"Don't act rashly, this may be his chance," said the old man.

After a while, the light on Lin Feng gradually disappeared, and he slowly opened his eyes, with a strange light flashing in his eyes.

"I seem to have realized something..." Lin Feng murmured to himself.

At this moment, the entire space began to tremble violently, and cracks appeared all around.

"Oh no, this space is going to collapse!" the old man said loudly.

The three of them quickly cast spells, trying to escape from this space. With their efforts, they finally escaped before the space completely collapsed.

They returned to the cave in Black Wind Mountain. At this time, the formation in the cave had disappeared, replaced by an ancient secret book.

The old man picked up the secret book, flipped through it, and a look of surprise appeared on his face: "This is the opportunity we are looking for. With this secret book, we will definitely gain something from this tribulation."

Lin Feng and Li'er smiled at each other. After going through untold hardships, they finally found their chance in the mortal world.

However, what they didn't know was that even greater challenges were waiting for them...
