Genshin Impact.

Under the guidance of the old man, Lin Feng and Li'er came down to the mortal world to experience hardships. The journey was full of unknowns and challenges.

They landed in a bustling town, where people were coming and going. Lin Feng was dressed in a green dress, with an extraordinary temperament, while Li Er was dressed in a lavender dress, beautiful and charming. The appearance of the two attracted many people's attention.

"Brother Lin Feng, this mortal world is so lively and bustling. It is very different from our fairyland." Li'er looked around curiously.

Lin Feng smiled slightly and said, "Yes, although this mortal world is not as peaceful and lofty as the fairyland, it also has its own unique charm."

The two of them were walking in the town, feeling the atmosphere of the mortal world. Suddenly, there was a noise, and a group of people gathered together, talking.

Lin Feng and Li Er approached and saw that it was an old man setting up a stall on the street, selling some strange items. Lin Feng's eyes were attracted by a jade pendant that was emitting a faint light and engraved with some mysterious patterns.

"Old man, what is the origin of this jade pendant?" Lin Feng asked.

The old man raised his head and glanced at Lin Feng, with a hint of surprise in his eyes: "Young Master, you have good eyesight. This jade pendant is a thing from the immortal family, but now it has lost most of its spiritual power."

Lin Feng's heart moved, feeling that the jade pendant might be related to their tribulations, so he bought it.

Just as they were about to leave, the sky suddenly became overcast and a strong wind blew. A black shadow flew through the air and instantly grabbed Li'er away.

"Li'er!" Lin Feng shouted and chased after her without hesitation.

The shadow was extremely fast, and Lin Feng chased after it relentlessly, eventually arriving at a gloomy valley. The valley was filled with thick fog, making it difficult to see the direction.

Lin Feng walked forward cautiously, and suddenly, a chill came over him, and a group of strange figures appeared around him. These figures bared their fangs and claws and pounced on Lin Feng.

Lin Feng used his magic to fight these strange figures fiercely. But these figures seemed endless, and Lin Feng gradually felt powerless.

At this moment, the jade pendant in his arms suddenly emitted a strong light, and wherever the light went, those strange figures disappeared.

Lin Feng continued to move forward and finally found Li'er in the depths of the valley. Li'er was imprisoned in a huge cage, surrounded by a powerful magic circle to guard her.

"Brother Lin Feng, you are finally here." Li'er had tears in her eyes.

Lin Feng looked at the magic circle, frowning, thinking about how to break it. At this moment, the light in the jade pendant shone again, and a mysterious voice sounded in his ears: "Keep the right path in your heart, and the immortal power will come naturally."

Lin Feng understood immediately, he closed his eyes, adjusted his breathing, and gathered his immortal power. When he opened his eyes again, a determined light flashed in his eyes.

Lin Feng formed seals with his hands and chanted something. Powerful immortal power surged out of his body and rushed towards the magic circle. Under the impact of the immortal power, cracks began to appear on the magic circle and eventually shattered.

Lin Feng rescued Li'er, and they hugged each other and cried.

"Brother Lin Feng, thanks to you." Li'er said.

"As long as you are safe." Lin Feng said with a smile.

However, before they could leave the valley, the dark shadow appeared again, blocking their way.

"Do you think you can leave like this? You are too naive!" The black shadow sneered.

Lin Feng and Li'er looked at each other with determination in their eyes. They knew that a fierce battle was inevitable.

Lin Feng took the lead in launching the attack. The immortal sword in his hand shone brightly and stabbed at the black shadow. The black shadow dodged Lin Feng's attack easily.

Li'er also used her magic, and beams of light shot towards the black shadow. The black shadow waved his hands, and a black barrier blocked Li'er's attack.

The two sides fought back and forth, and the battle entered a white-hot stage. Lin Feng and Li'er gradually became exhausted, but the black shadow was still strong.

Just when they felt despair, the jade pendant in Lin Feng's arms shone again, and a powerful force was injected into their bodies.

Lin Feng and Li'er suddenly felt a surge of strength, and they once again used their strongest magic to attack the black shadow.

The black shadow finally couldn't hold on and was defeated by Lin Feng and Li'er.

"You guys..." The black shadow dissipated unwillingly.

Lin Feng and Li Er walked out of the valley. The sky had cleared up. They looked back, feeling a lot of emotion in their hearts.

"Brother Lin Feng, this ordeal has made me understand a lot." Li'er said.

"Yes, we still have to go through more tests, but as long as we work together, we will be able to complete the mission." Lin Feng said.

The two continued on their immortal journey, their figures gradually went further and further away, but their story had just begun...
