Genshin Impact.

In the world of the original God's Path, Lin Feng and Li'er have come to a critical node after experiencing countless hardships and dangers. Their journey to the mortal world is full of unknowns and challenges, and the mysterious old man is always like a beacon, guiding them at critical moments.

Lin Feng stood tall, his eyes revealing determination and courage. He was dressed in a green robe, with a sword shining with cold light on his waist. Li'er was like a fairy descending from the earth, beautiful and charming, with a lively light flashing in her eyes, and a white dress fluttering in the wind.

They came to an unfamiliar valley, which was filled with a mysterious atmosphere. The valley was shrouded in mist, and some ancient ruins could be vaguely seen. Lin Feng and Li'er stepped into the valley carefully, always keeping alert.

Suddenly, a huge flame lion rushed out from the side. The flame lion's body was burning with raging flames, and its eyes were flashing with anger. Lin Feng immediately drew out his sword and prepared to fight. Li'er also used magic to bless Lin Feng with strength.

Lin Feng used a set of sharp sword techniques, the sword shadow flashed, and stabbed at the flame lion. The flame lion opened its bloody mouth and spewed out a stream of blazing flames. Lin Feng quickly dodged and looked for the flame lion's weakness.

After a fierce battle, Lin Feng finally found the weakness of the Flame Lion and defeated it with one blow. They continued to move forward and encountered many other dangers in the valley.

Once, they accidentally stepped into a trap and fell into a huge cave. The cave was dark and damp, filled with a pungent smell. Lin Feng and Li'er carefully explored the cave and found that there was a mysterious monster hidden here - the shadow spider.

The shadow spider was huge, pitch black, and its eyes flashed with strange light. It could hide in the dark, making it difficult to detect. Lin Feng and Li'er immediately became alert, as they knew that this monster was very dangerous.

Suddenly, a shadow spider rushed out from the darkness and attacked them. Lin Feng waved his sword to try to resist the attack of the shadow spider. Li Er used magic to illuminate the cave.

Under the illumination of Li'er's magic, Lin Feng finally saw the position of the shadow spider. He used his strongest swordsmanship and stabbed the shadow spider. After a hard fight, they finally defeated the shadow spider.

After climbing out of the cave, they continued to explore the valley. In an ancient relic, they found a mysterious fairy secret book. The secret book recorded a powerful fairy art, but it was very difficult to practice.

Lin Feng and Li Er decided to practice this secret book of immortal arts together. They found a quiet place and began to practice with concentration. In the process of practice, they encountered many difficulties. The practice of immortal arts requires strong spiritual power and mental strength, and they must constantly challenge their limits.

Lin Feng practiced hard every day, practicing the moves of the immortal arts over and over again. Li'er cheered him on and also constantly improved her own strength.

After a period of practice, they finally mastered the immortal arts in this immortal arts secret book. Their strength was greatly improved, and their hearts were filled with joy.

However, their adventure was not over yet. On the way forward, they encountered a huge storm. The storm was mixed with powerful spiritual power fluctuations, which made people feel palpitations.

Lin Feng and Li'er huddled together, using magic to try to resist the storm, but the storm was too strong and they were blown all over the place.

In the storm, they saw a mysterious figure. The figure flashed by, which made them very confused. They decided to chase this mysterious figure to see who it was.

After a difficult search, they finally found the mysterious figure. It turned out to be a mysterious immortal who was fighting a powerful monster.

Lin Feng and Li Er immediately joined the battle. They used their magic to fight against the monster together with the immortals. The monster was very powerful and its attack was hard to resist. But Lin Feng and his friends did not back down. They worked together and finally defeated the monster.

The immortal praised Lin Feng and Li Er for their bravery and strength. He told them that there were many powerful enemies and challenges waiting for them in this world. Only by constantly improving their strength could they go further on the immortal path.

Lin Feng and Li Er were deeply inspired and decided to continue practicing. Under the guidance of the immortal, they came to a mysterious place full of rich spiritual power.

Here, they began a more arduous training. Every day they immersed themselves in the world of immortal arts, constantly exploring and breaking through their own limits.

During the cultivation process, they also met some other immortal cultivators. These immortal cultivators came from different places, and they all had their own stories and goals. Lin Feng and Li Er communicated and exchanged ideas with them, learned from each other, and made progress together.

After a period of training, Lin Feng and Li Er's strength was improved again. They decided to leave this place and continue their adventure.

In the following journey, they encountered many more dangerous challenges. Once, they came to a mysterious island. The island was filled with a layer of mysterious fog, making it difficult to see the road ahead.

Lin Feng and Li Er stepped into the island carefully, and they found that there was a powerful monster hidden here - the Thunder Dragon. The Thunder Dragon was flashing with lightning all over its body, and its eyes revealed a majestic light.

Lin Feng and Li Er immediately prepared for battle. They used their magic to attack the Thunder Dragon. The Thunder Dragon was not to be outdone, and it spewed out a powerful lightning bolt, attacking Lin Feng and the others.

During the fierce battle, Lin Feng discovered that the Thunder Dragon's weakness was its head. He decided to take a risk and take the opportunity to attack the Thunder Dragon's head. He exerted his fastest speed and rushed towards the Thunder Dragon's head.

Li Er was protecting Lin Feng and using magic to restrain the Thunder Dragon. After a tough fight, Lin Feng finally succeeded in attacking the Thunder Dragon's head and defeated it.

They continued to explore the island and found some precious immortal medicines and magic weapons, which were of great help to their immortal cultivation.

With a full harvest, they left the island. On the way back, they met an injured cultivator. The cultivator told them that an evil force was rising not far away, and they were trying to destroy the whole world.

Lin Feng and Li Er decided to step forward and stop this evil force. They came to the base of the evil force and found that it was full of darkness.

They carefully sneaked into the stronghold and started a fierce battle with the members of the evil force. During the battle, they found that this evil force was very powerful and their magic seemed to have little effect on them.

Just when they felt desperate, Lin Feng suddenly remembered a mysterious magic that the old man had taught him. He decided to take a risk and use this mysterious magic.

The power of the mysterious magic was so strong that it instantly broke the defense of the evil forces. Lin Feng and Li Er took the opportunity to launch an attack and finally defeated the evil forces.

They successfully stopped the evil forces' conspiracy and saved the world, and in the process, they also gained a lot of valuable experience and growth.

Back to the original place, Lin Feng and Li Er found the old man. The old man was very satisfied with their performance. He told them that they had completed the mission of descending to the mortal world and could return to the fairyland.

Lin Feng and Li Er were filled with emotion. They had gone through countless hardships and obstacles during this journey to the mortal world, and also gained many valuable things. Their friendship had deepened, and their strength had also been greatly improved.

Under the guidance of the old man, they returned to the fairyland. In the fairyland, there was brilliant light and a peaceful atmosphere. Lin Feng and Li'er knew that their fairy journey was still long, but they were ready to meet the challenges of the future.
