Genshin Impact.

Lin Feng, Li'er and the mysterious old man were on a cloud, looking at the vast world below. This descent to the mortal world was a great test for them.

The three of them landed in front of an ancient mountain range. The mountain was rolling and shrouded in clouds and mist, and bursts of beast roars could be heard from time to time.

"This is a place of trial," the old man put his hands behind his back and looked at the mountains deeply, "Once you enter, life and death will be determined by fate."

Lin Feng's eyes were firm, and he bowed and said, "Don't worry, senior, I will do my best." Li'er also nodded, with a hint of determination in her eyes.

As they entered the mountains, the air around them seemed to become heavier. Lin Feng walked in front, holding his sword tightly in his hand, carefully observing the movements around him. Li'er followed closely behind, holding a jade flute in her hand, in case of emergency.

Suddenly, a huge python jumped out from the woods next to them, opened its bloody mouth and pounced on them. Lin Feng flashed, drew his sword, and with a flash of sword light, the python's head fell to the ground instantly. However, before they could breathe a sigh of relief, countless poisonous snakes appeared around them, spitting out their tongues and approaching them.

Li'er held the jade flute horizontally and played a wonderful melody, which turned into rays of light and shot towards the poisonous snakes. Under the shining light, the poisonous snakes turned into ashes one after another.

Continuing forward, they came across a broken bridge. Under the bridge was a bottomless canyon filled with thick fog.

"The bridge is broken, how can we get across?" Li'er frowned.

Lin Feng looked around and found some vines nearby. "We can use these vines to swing over."

After saying that, Lin Feng took the lead and grabbed a vine, swung it hard, and flew to the other side. Li'er followed closely behind. However, when they were halfway through their flight, a strong wind suddenly blew in the canyon, blowing them left and right.

Lin Feng tried hard to keep himself steady and finally reached the other side. However, Li'er was unable to grab the vines due to the strong wind and fell into the canyon.

"Li'er!" Lin Feng was horrified and jumped down the canyon without hesitation, wanting to save Li'er.

During the rapid fall, Lin Feng kept casting spells to try to slow down the speed of descent. Finally, when they were about to land, Lin Feng hugged Li'er and used magic to form a cushion on the ground, and the two landed safely.

"Lin Feng, thank you." Tears flashed in Li'er's eyes.

"It's okay, as long as you are safe." Lin Feng smiled slightly.

The two continued to move forward, and soon they came to a cave. A strange light flickered in the cave, and bursts of low roars could be heard from time to time.

Lin Feng walked into the cave carefully, and saw that the cave was full of various traps. He accidentally triggered a trap, and countless sharp arrows shot from all directions.

Li'er quickly cast a spell to form a shield that enveloped the two of them. The sharp arrows hit the shield, making a tinkling sound.

When the arrows stopped shooting, they continued on. Deep in the cave, they found a huge sarcophagus. The sarcophagus was engraved with mysterious runes and exuded a powerful aura.

Just as they approached the sarcophagus, it suddenly shook violently, and a black shadow jumped out of the sarcophagus and pounced towards them.

Lin Feng took a closer look and found that it was a powerful demon spirit. The demon spirit exuded a black aura and its eyes flashed blood-red light.

Lin Feng and Li'er fought side by side and started a fierce battle with the demon. Lin Feng's swordsmanship was sharp, and each sword contained powerful magic. Li'er's music magic also played a huge role, and rays of light continued to shoot at the demon.

With the tacit cooperation of the two, the demon gradually lost the upper hand. Finally, Lin Feng stabbed the demon's vital point with a sword and completely destroyed it.

After dealing with the demon, they continued to explore the cave. At the end of the cave, they found a stone door. A sparkling gem was inlaid on the stone door.

Lin Feng reached out and touched the gemstone, and the stone door slowly opened. Behind the door was a huge secret room, in which were placed various precious magic weapons and secret books.

"Are these all rewards for the trial?" Li'er looked at the magic weapons and secret books curiously.

Lin Feng shook his head: "I don't think things are that simple."

At this moment, a voice suddenly sounded in the secret room: "Congratulations on passing the first stage of the trial. Next, there will be more severe challenges."

As the voice fell, the secret room began to shake violently, and countless cracks appeared on the surrounding walls.

"Oh no, this place is going to collapse!" Lin Feng and Li'er quickly picked up some magic weapons and secret books, and then rushed towards the exit.

As soon as they ran out of the secret room, the cave collapsed completely. They looked at the ruins in front of them, their hearts filled with emotion.

"What should we do next?" Li'er asked.

Lin Feng looked into the distance: "Keep moving forward. I believe that as long as we work together, we will be able to complete this trial."

The two walked hand in hand towards the front, and what greeted them would be unknown challenges and opportunities...
