Genshin Impact.

After successfully sealing the evil power and saving the town, Lin Feng, Li'er and the old man did not stop. They knew that the journey to the mortal world had just begun, and there were many unknown challenges waiting for them.

On a sunny morning, the three decided to leave the town and continue their experience in this mortal world. Along the way, they walked through mountains, rivers, lakes, and dense forests, appreciating the beautiful scenery and customs of the mortal world.

One day, they came to a mountain range shrouded in clouds. The peaks were towering into the clouds, and there was a faint glow of light between the mountains, revealing a mysterious atmosphere. The old man looked at the mountain, a strange color flashed in his eyes, and he said softly: "This mountain is unusual, perhaps there is an opportunity related to our tribulation hidden in it."

Lin Feng and Li Er were excited when they heard this, and the three of them immediately stepped into the mountains. The mountain road was rugged and difficult to walk on, and there were bursts of beast roars from all around. But with their immortal cultivation, these dangers were not a big deal.

As they went deeper into the mountains, they found a hidden valley. In the valley stood an ancient ruin, the door of which was tightly closed and engraved with mysterious runes and patterns.

Lin Feng stepped forward and gently touched the door, and a powerful force bounced him back. The old man stepped forward and carefully observed the runes on the door. After thinking for a moment, he said, "This is an ancient relic. The runes on the door are a powerful seal. We need to find a way to break it before we can enter."

The three began to look for clues around the ruins. Lier found a broken stone tablet under a boulder with some vague words engraved on it. After the old man's interpretation, they learned that the key to breaking the seal was to find the five spirit beads scattered near the ruins.

So, they split into three groups and began to search for the spirit pearl. In a deep forest, Lin Feng encountered a powerful guardian monster. The monster was huge, exuding a strong demonic aura. It rushed towards Lin Feng with its fangs and claws bared. Lin Feng was not afraid of danger, and used his magic to fight the monster fiercely. After a hard fight, Lin Feng finally defeated the monster and found the first spirit pearl in the monster's lair.

Li'er encountered many traps in a cave on the edge of a cliff, but she cleverly avoided the traps with her agility and wit, and found the second spirit bead deep in the cave.

The old man found a hidden underwater palace at the bottom of a turbulent river. The palace was filled with various formations. With his profound attainments in immortal arts, the old man cracked the formations and found the third spirit bead.

After the three of them had collected three spirit beads, they continued to search for the remaining two. At the top of a mountain, they found a mysterious formation with a glowing light in the center. When they got closer, they saw that it was the fourth spirit bead.

However, the whereabouts of the last spiritual bead remained unknown. Just when they were at a loss, a sharp bird cry suddenly came from the sky. A huge divine bird fell from the sky, holding a spiritual bead emitting colorful light in its claws. It turned out that this divine bird was the guardian of the ruins, and it had been testing Lin Feng and his team. Seeing their courage and wisdom, the divine bird decided to give them the last spiritual bead.

After gathering all five spirit beads, they returned to the gate of the ruins. The old man inserted the spirit beads into the rune grooves on the door in a specific order, and with a flash of light, the gate slowly opened.

Stepping into the ruins, there was an ancient and mysterious atmosphere. In the center of the hall stood a huge stone platform, on which was placed a magic weapon that exuded a powerful aura. Lin Feng approached and saw that the magic weapon was shaped like a sword, with a crystal clear blade, a jewel inlaid on the hilt, and a wisp of fairy air surrounding it.

Just as Lin Feng was about to pick up the magic weapon, a low roar suddenly sounded from the ruins. Then, a black shadow rushed out from the darkness and rushed towards Lin Feng. The old man was quick-witted and waved his sleeves. A stream of immortal power was released, and the black shadow was repelled.

The shadow revealed its figure, and it turned out to be an ancient demon beast. Its eyes were red, and it exuded an evil aura. It had coveted this magic weapon for a long time, and had been guarding it in the ruins.

A fierce battle began. Lin Feng, Li Er and the old man cooperated with each other and displayed various magical skills. The monster was powerful, spewing black flames from its mouth and waving its claws, bringing gusts of wind. But with the concerted efforts of the three, the monster gradually fell into a disadvantage.

Finally, Lin Feng saw the right moment, held the sword, and launched a full-strength attack. A flash of light passed, and the monster was completely defeated. After the battle, Lin Feng picked up the magic weapon and carefully felt the powerful power contained in it.

The old man said: "This magic weapon is called the 'Star Sword'. It is an ancient artifact with great power. In the next tribulation, it may become a great help to us."

The three of them left the ruins with the Star Sword and continued their journey. However, what they didn't know was that their acquisition of the Star Sword had attracted the attention of some evil forces in the mortal world...
