Genshin Impact.

After successfully overcoming their mental tribulation, Lin Feng and Li Er's mental state had undergone a great transformation. They stood on the top of the mountain, looking at the misty mountains in the distance, with a myriad of emotions in their hearts.

The old man appeared behind them at some point, stroked his beard, and with wisdom in his eyes, he said, "Your heart tribulation has passed, but your immortal path is still long. Next, you need to continue to train in this world before you can truly comprehend the true meaning of immortality."

Lin Feng and Li Er looked at each other, their eyes full of determination. They knew that the road ahead was full of challenges, but they were not afraid.

"Master, where should we go next?" Lin Feng asked.

The old man smiled slightly, raised his hand and waved it, and a map appeared in front of them. "This place is called Canglan City. There have been strange things happening in the city recently, you can go and find out what's going on."

Lin Feng and Li'er nodded, and without any hesitation, they immediately set off for Canglan City. Along the way, they saw many scenes they had never seen before. The prosperous towns, the bustling markets, the hardworking people, all of which gave them a deeper understanding of the world.

After arriving at Canglan City, they discovered that beneath the city's apparent prosperity, there seemed to be a mysterious power hidden. From time to time, a strange atmosphere permeated the city, making people shudder.

"Brother Feng, I feel something weird here." Li'er pulled the corner of Lin Feng's clothes tightly.

Lin Feng gently patted Li'er's hand and comforted her, "Don't be afraid, I'm here. Let's go find out the situation first."

They asked around in the city and learned that many people had disappeared at night recently, and the missing people were all young and strong men and women. For a time, the people in the city were panicked and rumors spread everywhere.

Lin Feng and Li'er decided to wait at night to see if they could find any clues. As night fell, the entire Canglan City was shrouded in darkness. Lin Feng and Li'er hid in the dark, waiting quietly.

After an unknown amount of time, a gust of cold wind blew and a black shadow flashed before their eyes. Lin Feng and Li Er immediately chased after it. The black shadow was extremely fast, shuttling through the alleys in the city. Lin Feng and Li Er chased after it closely, and finally, in front of an abandoned temple, the black shadow disappeared.

They walked into the temple carefully, and there was a foul smell in the air. In the center of the temple, there was a huge altar, which was engraved with strange runes.

"What is this?" Li'er looked at the altar, her heart full of doubts.

Lin Feng frowned and observed the rune carefully. Suddenly, the rune flashed with a strange light, and a huge monster slowly rose from the altar. The monster bared its fangs and claws and pounced towards Lin Feng and Li'er.

Lin Feng and Li Er immediately used their magic to start a fierce battle with the monster. The monster was very powerful, and each attack contained great power. Lin Feng and Li Er gradually fell into trouble.

Just when they were about to collapse, the old man suddenly appeared. He held a staff in his hand, and with a wave of the staff, a beam of light shot towards the monster. Under the illumination of the light, the monster howled in pain and gradually turned into ashes.

"Master!" Lin Feng and Li'er shouted in surprise.

The old man nodded and said, "This is a demon beast controlled by evil forces, and it specializes in sucking people's essence. You did a good job this time, but you need to be more careful."

After defeating the monster, Canglan City returned to its former tranquility. Lin Feng and Li'er continued on their immortal journey. They traveled through mountains, rivers, lakes, jungles and deserts, exorcised demons and monsters along the way, and helped many people.

During one of their trips, they met a mysterious woman, dressed in white, with an extraordinary temperament, as if she was not of this world.

"You are Lin Feng and Li'er, right?" the woman said.

Lin Feng and Li'er looked at each other, their hearts filled with confusion. "Who are you? How do you know our names?"

The woman smiled and said, "My name is Murong Xue, and I am an immortal cultivator. I heard about your deeds and came here to meet you."

Lin Feng and Li Er were wary of Murong Xue's arrival. Murong Xue seemed to see through their thoughts and said, "Don't worry, I have no ill intentions. I just want to go forward with you and explore the mysteries of this immortal path together."

Lin Feng and Li'er thought about it for a moment and felt that what Murong Xue said made sense, so they agreed to her request. From then on, the three of them traveled together, and there were many more wonderful stories on the immortal road.

They came to a place called Qingyun Mountain. It is said that there is a mysterious cave on the mountain, which contains endless treasures and immortal cultivation secrets. However, Qingyun Mountain is steep, foggy and full of dangers.

Lin Feng, Li Er and Murong Xue were not afraid and decided to climb Qingyun Mountain. On the mountain, they encountered various ferocious monsters and complex traps. But with their wisdom and courage, they escaped danger again and again.

Finally, they found the mysterious cave. The door of the cave was closed, and a complex formation was engraved on the door.

"This formation is so powerful, how can we break it?" Li'er asked.

Murong Xue observed carefully for a while and said, "I have some knowledge of formations. Let me give it a try."

Murong Xue used her magic to crack the formation. After some effort, the formation was finally cracked and the door slowly opened.

However, the moment they entered the cave, a powerful force enveloped them. Countless illusions appeared before their eyes, some of which were gold and silver treasures, some were peerless immortal magic, and some were power and status.

"This is an illusion, everyone be careful!" Lin Feng shouted at the top of his lungs.

They tried to stay awake and resist the erosion of the illusion. Finally, with their joint efforts, the illusion was broken. They found an ancient immortal cultivation secret book and some precious magic weapons in the cave.

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

"Leave behind the secret books and magic weapons, otherwise you can't leave!" said the leader of the mysterious people.

Lin Feng, Li Er and Murong Xue did not retreat, they once again used their magic to fight a desperate battle with the mysterious man. The battle was extremely fierce, and both sides used all their strength.

At the critical moment, Lin Feng realized a new magic, and his strength increased greatly. He used the powerful magic to defeat the mysterious man in one fell swoop.

With the secret manual and magic weapon, they left Qingyun Mountain and continued their immortal journey. Their story continues...
