Genshin Impact.

Under the guidance of the mystery in the mirror, Lin Feng and Li'er continued their journey to the mortal world to experience hardships.

They came to a prosperous town, which was bustling with traffic, but Lin Feng and Li'er had no intention of appreciating the hustle and bustle of the world. Because they knew very well that in this seemingly ordinary world, there were countless tests and mysteries hidden.

Before parting with them, the old man gave them some obscure hints, but Lin Feng and Li'er had not yet fully understood them. These hints were like a mystery, lingering in their hearts, and they could never let it go.

Lin Feng frowned and thought: "Li'er, how should we understand the old man's words?" Li'er shook her head slightly, indicating that she didn't know where to start. The two fell into silence, their hearts full of doubts and uneasiness.

At this moment, a melodious sound of a zither came, attracting their attention. They looked in the direction of the sound and saw a man in white playing the zither in front of a restaurant. His fingering was skillful, and the sound of the zither was melodious and intoxicating.

Lin Feng and Li Er were moved by the wonderful music. They listened quietly, as if forgetting all their worries. When they came to their senses, they found that the people around them were already immersed in the music, with happy smiles on their faces.

Lin Feng suddenly realized that maybe this was what the old man wanted to tell them. In this bustling town, everyone has their own life and story, and music has become a bridge connecting people's emotions. It can make people forget their troubles and feel inner peace and tranquility.

Li'er also said thoughtfully: "Perhaps, we should learn to feel the world with our hearts, and appreciate the beauty in the ordinary. In this way, we can better complete this journey of tribulation." Lin Feng nodded in agreement, and the two decided not to dwell on the old man's tips, but to experience this worldly life in their own way.

So, they began to integrate into the town, communicate and interact with the people. They helped the elderly cross the road, delivered food to poor families, and even participated in a grand wedding. In the process, they gradually realized the meaning and value of life and understood what true happiness is.

However, just as they were immersed in this wonderful atmosphere, a sudden disaster struck. The town suffered a rare flood, many houses were submerged, and the people were displaced. Lin Feng and Li Er were extremely anxious, and they did not hesitate to devote themselves to the rescue work.

In this disaster, they saw the brilliance and darkness of human nature. Some people bravely stepped forward to save others, while others took the opportunity to rob property and lost their morals. Lin Feng and Li Er experienced many challenges and difficulties in the process, but they always adhered to their beliefs and tried their best to help the people affected by the disaster.

Eventually, the flood receded and the town regained its former vitality. Lin Feng and Li Er stood on the ruins, feeling deeply moved. They understood that this disaster was not only a test for them, but also a kind of growth. Through this experience, they strengthened their faith and were determined to use their own strength to change the world.

As time went by, Lin Feng and Li'er's experience became deeper and deeper, and their minds became more mature. In the process, they gradually solved the mystery left by the old man and found their own answers.

"Lin Feng, what should we do next?" There was a hint of confusion in Li'er's eyes.

Lin Feng looked into the distance with a determined gaze and said, "No matter what, let's learn more about the situation in this town first, maybe we can find some clues."

As they ask around town, trying to find information about their mission, they encounter an odd merchant.

The businessman looked at Lin Feng and Li Er, with a shrewd look in his eyes: "You two don't look like locals, but are you looking for something special?"

Lin Feng's heart moved, thinking that this businessman might know something, but he didn't dare to easily reveal his purpose, so he just said vaguely: "We just traveled here and were curious about this place."

The merchant chuckled and said, "I don't think so, but I have lived in this town for many years and I know a lot of strange things."

Li'er quickly said, "Then could you please tell me about it?"

The merchant nodded and began to tell some legends about a mysterious place near the town. Lin Feng and Li'er listened carefully, trying to find useful clues.

However, it is difficult to tell whether the businessmen's words are true or false, and they need to distinguish them carefully.

After leaving the merchant, they continued to explore the town. In a corner, Lin Feng found a mysterious symbol that was somewhat similar to some of the patterns they saw in the mirror.

"Lier, look at this." Lin Feng said, pointing at the symbol.

Li'er came over to observe carefully: "Could this be the clue we are looking for?"

Just as they were thinking, a strong wind suddenly blew and the surrounding scene became blurred in an instant.

When the wind died down, they found themselves in a strange place, surrounded by a barren desert.

"What's going on?" Li'er was a little panicked.

Lin Feng comforted: "Don't be afraid, we will definitely find a way out."

They trudged forward in the desert, thirsty and exhausted. But just when they were about to despair, they found an ancient temple.

The temple gate was closed, but a mysterious power emanated from inside.

Lin Feng hesitated for a moment, but finally decided to push the door open. The scene inside the door surprised them, as it was filled with all kinds of strange runes and magic weapons.

Just when they wanted to explore further, a mysterious figure suddenly appeared.

"Why did you break in here?" The figure's voice was low and majestic.

Lin Feng said respectfully: "We have no intention of offending you, we are just looking for the truth on the way to immortality."

The mysterious figure was silent for a moment, then said: "In that case, then you will accept the test here."

After saying that, rays of light shot towards Lin Feng and Li'er, and the test began...

Can they pass the test and find the true meaning of immortality? Everything is still unknown.
