Genshin Impact.

After experiencing all kinds of hardships, Lin Feng and Li'er did not stop their steps after they settled down on the immortal path and returned to their true selves.

One day, they came to a prosperous town. There were shops on both sides of the street, people were coming and going, and it was very lively. Lin Feng looked at this bustling scene, and his heart was filled with emotion.

"Li'er, the mundane atmosphere of this world really makes people feel both familiar and strange." Lin Feng said to Li'er beside him with a smile.

Li'er nodded gently, her eyes full of curiosity: "Yes, Brother Lin Feng, this place is completely different from the fairyland we were in before."

As they were walking down the street, an old man caught their attention. The old man was in ragged clothes, but his eyes were bright and he exuded a mysterious aura.

Lin Feng walked up and asked politely, "Old man, what are you doing here?"

The old man glanced at him and said slowly, "Young man, I see that you two are not ordinary people, but you come to travel in this mortal world. I think you must have a special opportunity."

Lin Feng and Li'er looked at each other, secretly surprised at the old man's insight.

"Old man, you are right. We came down to the mortal world to experience hardships in order to seek a higher realm of immortality." Lin Feng said frankly.

The old man smiled slightly: "If that's the case, then everything in this world may bring you unexpected gains."

After saying this, the old man turned and left.

Lin Feng and Li Er decided to follow the old man's guidance and explore more mysteries in this town. They found that although the people here live ordinary lives, everyone has unique stories and emotions.

In a teahouse, they heard a storyteller's wonderful narration. In the story, there are heroic ambitions and passions, as well as the joys and sorrows of ordinary people. Lin Feng and Li'er were immersed in it, feeling the sincerity and depth of human emotions.

"Lier, these stories made me understand that the path of immortality is not just about the pursuit of power, but also about the understanding and tolerance of all things in the world." Lin Feng said thoughtfully.

Li'er nodded and said, "Brother Lin Feng, I feel the same way."

As the days passed, Lin Feng and Li Er helped many people in need. They used magic to treat diseases for the poor and rebuild homes for those who suffered disasters.

However, their actions attracted the attention of some lawless people who were jealous of Lin Feng and Li Er's abilities and attempted to harm them secretly.

One night, when Lin Feng and Li'er were resting, they were suddenly surrounded by a group of men in black.

"You nosy guys, today is your doom!" said the leader of the men in black viciously.

Lin Feng and Li'er were not afraid of danger. They used their magic to engage in a fierce battle with the men in black.

Just when the battle was at a stalemate, the mysterious old man suddenly appeared. The old man held a cane in his hand and waved it gently, and the man in black was instantly repelled by the powerful force.

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

The old man smiled and said, "You're welcome. This is the reward you deserve for your kindness."

After this incident, Lin Feng and Li Er became more determined to practice in the mortal world. They continued to move forward, helping more people, and in the process, they continued to comprehend the true meaning of the immortal way.

By chance, they learned about a mysterious mountain, which was said to hide a powerful secret book of immortality.

Lin Feng and Li Er decided to go explore. The mountain was steep and rugged, surrounded by clouds and mist. During their climb, they encountered violent storms and steep cliffs.

But with their firm belief and mutual support, they finally reached the top of the mountain.

In an ancient temple on the top of the mountain, they found the secret book of immortality. However, the words on the secret book were obscure and difficult to understand, requiring them to comprehend them carefully.

Lin Feng and Li Er calmed down and studied the secret book carefully. After several days of hard work, they finally understood the secret.

"Lier, the harvest this time is really huge." Lin Feng said excitedly.

Li'er smiled and said, "Yes, Brother Lin Feng, we have taken another step forward on our path to immortality."

With new insights and strength, Lin Feng and Li'er continue to move forward on the immortal journey in the mortal world, facing more challenges and opportunities.
