Genshin Impact.

In the mysterious fairyland, Lin Feng and Li'er were standing on the edge of a misty cliff, their eyes revealing determination and confusion. The old man beside them had white hair, but his eyes were as deep as the abyss, as if he could see through everything in the world.

Lin Feng, with a tall and straight figure and handsome face, has a look of desire and courage for the unknown. He is dressed in a white robe, with an ancient long sword on his waist, and his long hair fluttering in the wind, like an immortal walking out of a painting. Li'er is beautiful, with eyes like stars, long hair like a waterfall, wearing a light blue dress, holding an exquisite staff in his hand, exuding a mysterious atmosphere.

They came to the mortal world to hone their immortal hearts and find the truth hidden in the fog. The old man was their guide, giving them guidance and help at critical moments.

When they stepped into the mortal world, the first thing they faced was a dense forest. The forest was filled with thick fog, making it difficult to see the road ahead. Lin Feng tightly grasped the sword in his hand and looked around vigilantly. Li'er waved her staff, releasing a faint light, trying to dispel the fog.

"Be careful, there may be many dangers hidden in this forest." The old man's voice sounded in their ears.

They walked forward cautiously, and suddenly, a huge beast rushed out from the woods. The beast was huge, its hair was as hard as steel needles, and its eyes flashed with a fierce light. Lin Feng drew his sword without hesitation and faced the beast. Li Er also quickly performed magic to bless Lin Feng with strength.

Lin Feng's sword drew a graceful arc in the air, and slashed at the beast with fierce momentum. The beast roared, waving its huge claws and rushing towards Lin Feng. Lin Feng dodged to the side, avoiding the beast's attack, and then stabbed the beast's abdomen with his sword. The beast roared in pain, turned around and rushed towards Lin Feng. Lin Feng swung his sword again and started a fierce battle with the beast.

During the battle, Lin Feng gradually realized the essence of some immortal arts. He found that by using immortal power, he could make his attacks more fierce and his defense more solid. He began to try to integrate immortal power into his swordsmanship to create more powerful moves.

Li'er also continued to perform magic to support Lin Feng. Her magic could heal Lin Feng's injuries, enhance his strength, and attack wild beasts. With their joint efforts, they finally succeeded in defeating the wild beast.

After this battle, they became more resolute in their faith. They knew that in the mortal world, they would face more dangers and challenges, but they were not afraid because they had each other's company and the power of immortal arts.

They continued to move forward and came to an ancient town. The town was filled with a mysterious atmosphere, making people feel as if they had entered a different world. They met all kinds of people in the town, including kind people and evil forces.

In the town, they heard a legend about a mysterious ruin. It is said that there are powerful magic and treasures hidden in the ruins, but it is also full of dangers and challenges. Lin Feng and Li Er decided to go to the ruins to find the hidden power.

On the way to the ruins, they encountered many difficulties and challenges. They needed to cross a desert, which was extremely hot and full of wind and sand. Lin Feng and Li Er had to use magic to create a protective shield to resist the invasion of wind and sand. They also needed to cross a wide river, which was fast-flowing and full of dangers. Lin Feng and Li Er used magic to create a small boat and successfully crossed the river.

Finally, they arrived at the entrance of the mysterious ruins. The entrance of the ruins was filled with thick fog, making it difficult to see what was inside. Lin Feng and Li'er walked into the ruins carefully and found that it was full of various mechanisms and traps. They needed to use magic to crack these mechanisms and traps before they could move forward.

In the ruins, they encountered many powerful enemies. Some of these enemies were evil monsters, and some were cursed souls. They all possessed powerful strength and evil spells. Lin Feng and Li'er had to go all out and use the magic they had learned to fight fiercely with the enemies.

During the battle, Lin Feng constantly comprehended new magic skills, and his strength was constantly improving. Li'er also played her own advantages in the battle. Her magic skills could heal Lin Feng's injuries and attack the enemy. They cooperated with each other, fought together, and gradually overcame difficulties one after another.

However, just when they thought they were about to find the treasure and magic, they fell into a more dangerous situation. They found themselves surrounded by a powerful evil force that intended to seize their magic and treasure and destroy the entire world.

Lin Feng and Li Er were in deep trouble, they didn't know how to deal with this powerful evil force. Just when they felt desperate, the old man's voice rang in their ears.

"Don't be afraid, children. You have powerful magic and firm beliefs. As long as you unite and play to your strengths, you will be able to defeat evil."

The old man's words cheered Lin Feng and Li Er up. They decided to join forces to fight against the evil forces and protect world peace. They used magic to create a powerful barrier to trap the evil forces inside. Then, they began to use their most powerful magic to attack the evil forces.

In the fierce battle, Lin Feng and Li Er constantly comprehended new magic skills, and their strength was constantly improving. In the end, they successfully defeated the evil forces and protected world peace.

They found powerful magic and treasures in the ruins, which would help them go further on the immortal path. With these gains, they left the ruins and continued their journey to the immortal path.

During the journey, they met many like-minded people, and together they formed a team to explore the mysteries of the immortal way. They learned from each other, helped each other, and grew together in the team.

As their strength continues to increase, they also face more severe challenges. They need to face more powerful enemies and solve more complex puzzles to move forward. However, they are not afraid, because they have each other's company, firm beliefs, and powerful magic.

They know that they still have a long way to go on the path to becoming immortals, but they believe that as long as they persevere, they will be able to achieve their goals and become true immortals.
