Genshin Impact.

Under the guidance of the old man, Lin Feng and Li Er descended to the mortal world to experience the tribulations. They were in the bustling world, but they were not confused by the hustle and bustle in front of them, and they always had the pursuit of spiritual light in their hearts.

Lin Feng was dressed in a green shirt, with sharp eyebrows and bright eyes, and he looked extraordinary. Li Er was dressed in a pink silk skirt, with a firm look in her lively eyes.

They walked along the way and came to an ancient town. The town was crowded and bustling. Lin Feng and Li'er shuttled through the crowd, trying to find clues to the spiritual light.

"Brother Lin Feng, we have been looking for a long time. Where is this spiritual light?" Li'er frowned slightly, looking puzzled.

Lin Feng patted Li'er's shoulder and comforted her, "Don't worry, since the spiritual light has led us here, there must be a deep meaning behind it."

Just when they were confused, a mysterious figure flashed by at the corner of the street. Lin Feng was quick to notice the anomaly and pulled Li'er to chase after it.

The mysterious figure turned left and right in the alley and finally disappeared in front of a dilapidated courtyard. Lin Feng and Li'er walked into the courtyard carefully and saw an old man sitting on a stone bench in the courtyard.

The old man looked at them with deep eyes and said, "You are finally here."

Lin Feng bowed and said, "Senior, do you know the whereabouts of Lingguang?"

The old man smiled, stood up and said, "Follow me."

They followed the old man to a secret room filled with ancient artifacts. The old man pointed to a painting on the wall and said, "This is the clue to the spiritual light."

Lin Feng and Li'er carefully observed the painting, which showed a mysterious forest.

"This forest seems to hide many secrets." Li'er said softly.

The old man nodded and said, "Yes, the spiritual light is in this forest, but it is full of dangers, so you must be careful."

Lin Feng and Li'er thanked the old man and resolutely embarked on the journey to the mountains and forests.

The forest was filled with mist, and it was eerie and scary. Lin Feng held his sword tightly, protecting Li'er.

Suddenly, a gust of wind whistled past, and a huge monster appeared in front of them. The monster bared its fangs and claws and pounced on them.

Lin Feng was not afraid at all, he raised his sword to meet the enemy. He was agile and his swordsmanship was sharp, he started a fierce fight with the monster.

Li'er cheered for Lin Feng from the side and cast magic to assist Lin Feng.

After a hard fight, Lin Feng finally killed the monster. They continued to move forward and encountered various traps.

But with their firm belief and extraordinary wisdom, they were able to overcome danger time and time again.

Deep in the forest, they found an ancient cave, which was filled with a mysterious atmosphere and the spiritual light seemed to be inside.

Lin Feng and Li'er walked into the cave carefully, and saw a gem emitting strange light in the center of the cave.

"This must be the spiritual light we are looking for." Lin Feng said.

Just as they were about to reach out for the spiritual light, a powerful barrier suddenly appeared and blocked them out.

"It seems that it is not easy to obtain spiritual light." Li'er said.

Lin Feng pondered for a moment and said, "Let's find a way to break the barrier together."

They searched for clues in the cave and finally found an ancient book which recorded the method to break the barrier.

Following the methods in the classics, Lin Feng and Li'er worked together and finally broke the barrier and successfully obtained the spiritual light.

However, just as they were about to leave the cave, a group of mysterious people suddenly appeared and blocked their way.

"Hand over your spiritual light and I will spare your lives!" said the mysterious man in the lead.

Lin Feng and Li'er looked at each other, knowing that a fierce battle was inevitable.

Lin Feng held a long sword and Li'er cast magic, and they fought a desperate battle with the mysterious man.

During the battle, Lin Feng and Li Er gradually gained the upper hand. Seeing that the situation was not good, the mysterious people fled.

Lin Feng and Li'er walked out of the forest with spiritual light and returned to the town.

They handed the spiritual light to the old man, who said with satisfaction: "You have passed the test, and your future immortal path will be brighter."

Lin Feng and Li Er smiled at each other. They knew that this was just a small challenge on the way to immortality, and there would be more difficulties waiting for them in the future. But they were not afraid at all, because they had firm beliefs and a persistent pursuit of immortality in their hearts.

As Lin Feng and Li'er walked further and further away, their immortal journey continued, full of unknowns and hopes...
