Genshin Impact.

When the immortal calamity came, Lin Feng and Li Er were drawn into the mortal world by a powerful force. When they opened their eyes again, they found themselves in a strange world.

There was a dense forest all around, and the sun shone through the gaps between the leaves, forming patches of light. Lin Feng stood up, patted the dust off his body, turned his head and looked at Li'er, only to see that her face was also full of confusion.

"Brother Feng, where are we now?" There was a hint of fear in Li'er's voice.

Lin Feng gently held Li'er's hand and comforted her: "Don't be afraid, since we have come down to the mortal world to experience tribulations, this must be the mortal world. I just don't know what will be waiting for us next."

At this moment, an old man suddenly appeared in front of them. The old man was wearing a gray robe, his hair was gray, but his eyes revealed a wise light.

"You two little guys are finally here." The old man's voice was low and hoarse.

Lin Feng looked at the old man warily and asked, "Who are you? Why are you here?"

The old man smiled slightly and said, "I am your guide in the mortal world. In the days to come, I will guide you through your tribulations."

Lin Feng and Li'er looked at each other. Although they still had doubts in their hearts, there was no other way at the moment, so they had to trust the old man temporarily.

The old man led them out of the forest and came to a small town. The town was bustling with people, and people's faces were filled with ordinary and happy smiles.

"Here, you have to learn to integrate into the life of mortals and experience the ups and downs of life. Only in this way can you complete your tribulation." said the old man.

Lin Feng nodded and took Li'er to explore the town. They found a job and helped out in an inn. As the days passed, Lin Feng and Li'er gradually adapted to the life of mortals.

However, the peaceful days did not last long. One night, a group of mysterious men in black suddenly appeared in the town. They burned, killed, looted and committed all kinds of evil.

When Lin Feng and Li Er saw this scene, they felt a sense of justice and decided to step forward to protect the residents of the town.

Lin Feng used his magic to fight the man in black fiercely, while Li Er cheered him on and used her magic to treat the injured residents.

With their efforts, the men in black gradually lost the upper hand and finally fled in disgrace. The residents of the town were grateful to Lin Feng and Li Er and regarded them as heroes.

However, their actions also attracted the attention of some people. A mysterious man appeared in front of them, wearing a silver mask on his face, making it difficult to see his face.

"You two have ruined my plan." The man's voice was icy cold.

Lin Feng frowned and asked, "Who are you? Why do you want to hurt these innocent people?"

The man sneered and said, "It doesn't matter who I am. What matters is that you are in big trouble."

After saying that, the man turned and left. Lin Feng and Li'er knew that a bigger crisis was coming.

The old man appeared again. He looked at Lin Feng and Li'er and said, "You have taken the first step in your tribulation. The road ahead will be even more difficult. Are you ready?"

Lin Feng and Li'er nodded firmly. They knew that no matter how many difficulties lay ahead, they would not back down.

Under the guidance of the old man, Lin Feng and Li Er embarked on a new journey. They walked through mountains and rivers, crossed deserts and wastelands, and encountered various challenges and tests along the way.

During one of their adventures, they strayed into a mysterious valley filled with thick fog and filled with eerie laughter.

Lin Feng and Li'er walked forward cautiously, when suddenly a huge monster rushed out from the thick fog, with its fangs and claws bared, and pounced on them.

Lin Feng and Li Er were not afraid, they fought side by side and fought a desperate battle with the monster. After a fierce battle, they finally defeated the monster.

However, before they had time to catch their breath, another group of demons came from all directions. These demons were powerful, and Lin Feng and Li'er gradually fell into trouble.

Just when they were about to collapse, a beam of light descended from the sky and dispersed all the demons. It turned out that it was the old man who came to their aid.

"You have done well, but it is not enough. The test of the immortal calamity is still going on, and you need to work harder." said the old man.

Lin Feng and Li'er wiped the sweat off their faces and nodded. They knew they still had a long way to go.

As time went by, Lin Feng and Li Er's strength continued to improve. Their experiences in the mortal world also greatly changed their state of mind.

However, they never forgot their mission. They knew that only by successfully surviving the immortal calamity could they return to the immortal world.

By chance, Lin Feng and Li Er got a mysterious ancient book, which recorded a powerful immortal method that could greatly improve their strength if they could practice it successfully.

They decided to practice in seclusion, striving to master this immortal technique as soon as possible. During the seclusion, they encountered many difficulties, but they never gave up.

After months of hard work, they finally succeeded in practicing this immortal technique. Their strength has been qualitatively improved and is now sufficient to cope with the next challenge.

At this time, news came from the Immortal Realm that the Immortal Tribulation was about to enter its final stage. Lin Feng and Li'er knew that the time for the decisive battle had arrived.

They bid farewell to the old man and set out on the journey back to the fairyland. On the way, they encountered countless enemies, but they defeated them one by one with their strong strength and firm belief.

Finally, they returned to the fairyland. The final test of the fairyland was for them to face a powerful demon god. The demon god had the power to destroy the heavens and the earth, and was the enemy of the fairyland.

Lin Feng and Li Er did not retreat at all, and they fought a world-shaking battle with the demon god. In the battle, they supported and cooperated with each other, and exerted their strongest strength.

After a hard battle, they finally defeated the demon and successfully survived the immortal calamity.

Everyone in the fairy world cheered for them, and they became heroes of the fairy world. However, Lin Feng and Li Er knew that all this was hard-won. Their experience in the mortal world would become the most precious wealth in their lives.
