Genshin Impact.

Under the guidance of the old man, Lin Feng and Li Er descended to the mortal world to experience various setbacks. At this time, they stood in front of an ancient town, ready to meet new challenges.

The town was bustling with people coming and going, but Lin Feng and Li'er had no intention of appreciating the prosperity of this world. They knew that every step might hide unknown tests.

"Li'er, you must be extra careful during this ordeal." Lin Feng said to Li'er with concern.

Li'er nodded gently, "Brother Lin Feng, you too."

As they walked into the town, they were greeted by the strong smell of the daily life. In the streets and alleys, the sounds of shouting and bargaining could be heard one after another.

Suddenly, a little boy ran by and accidentally bumped into Li'er.

"Ouch!" Li'er cried out softly.

Lin Feng quickly supported Li'er. The little boy looked at them in horror, "I'm sorry, I'm sorry!"

Lin Feng said gently: "It's okay, little friend, why are you in such a hurry?"

The little boy had tears in his eyes, "My mother is sick, I want to find a doctor."

Lin Feng and Li Er looked at each other and decided to help the little boy. They followed the little boy to his home and saw a woman lying on the bed in a dilapidated house with a pale face.

Li'er stepped forward to feel the woman's pulse, "Brother Lin Feng, this lady is overworked and has caught a cold. She needs some herbal treatment."

Without saying anything, Lin Feng went to look for herbs. In the process of looking for herbs, they met a mysterious old man.

The old man looked at Lin Feng and Li'er with deep eyes, "Young man, this herb is not easy to find, why are you taking so much trouble?"

Lin Feng bowed and said, "Old man, we feel sorry for this family and want to do our best to help them."

The old man smiled and said, "Good, good. There are herbs you need on the nearby mountain, but the mountain road is rugged and dangerous."

Lin Feng and Li Er walked up the mountain without hesitation. The mountain road was just as the old man said, steep and difficult to walk on, and wild animals appeared from time to time.

Li'er accidentally stepped on a loose stone and was about to roll down the mountain. Lin Feng was quick to grab Li'er and said, "Be careful!"

After a difficult climb, they finally found the herbs.

When they returned to the boy's house with the herbs, the woman's condition had improved.

"Thank you, you are such nice people." The little boy burst into tears of gratitude.

Lin Feng and Li'er smiled at each other and continued on their journey of experiencing tribulations.

Soon, they came to a temple where a senior monk was preaching.

Lin Feng and Li'er sat quietly by the side and listened. The monk's words were like a bright light, illuminating the doubts in their hearts.

"The mortal world is like a dream, and the path to immortality is also like a dream. Only by keeping your original heart can you be liberated." said the monk.

Lin Feng seemed to be thinking about something, while Li'er fell into deep thought.

After leaving the temple, they encountered a group of robbers. The robbers blocked their way and said, "Leave your money and I will spare your life!"

Lin Feng stepped forward and said, "How dare you do such an evil thing in broad daylight!"

After a fierce fight, Lin Feng and Li'er successfully repelled the robbers.

Through these experiences, Lin Feng and Li'er's state of mind gradually changed.

They began to understand that the path to immortality is not just about pursuing the improvement of strength and realm, but also about the understanding and perception of human nature and all things in the world.

At this moment, a strange light suddenly appeared in the sky.

"This is..." Lin Feng looked at the sky in surprise.

Li'er said, "Perhaps this is a new test."

They followed the light and came to a mysterious valley. The valley was filled with fog, making it difficult to see the road ahead.

Lin Feng and Li'er walked into the valley carefully. What challenges and opportunities were waiting for them...
