Genshin Impact.

After going through many hardships in the Immortal Fate Secret Realm, Lin Feng and Li Er finally found an opportunity to break through. They successfully improved their cultivation and strength, but this was only a small part of their journey to immortality.

After leaving the secret realm of immortality, Lin Feng and Li Er, under the guidance of the old man, began their journey to the mortal world. They landed in a bustling mortal world, where there were a lot of cars and people coming and going, which was completely different from the immortal world where they had always lived.

When they first arrived in the mortal world, Lin Feng and Li Er were full of curiosity about everything around them. The streets were lined with a wide variety of goods, and the sounds of shouting and bargaining were heard one after another. They shuttled among the crowds, feeling the atmosphere of fireworks in the mortal world.

"Brother Lin Feng, it's so lively here." Li'er's eyes sparkled with excitement.

Lin Feng smiled and nodded, "Yes, but we must not forget our mission when we come to the mortal world to experience disasters this time."

During their time in the mortal world, Lin Feng and Li'er began to learn to adapt to the life of mortals. They found a simple residence and began to be self-reliant. With the skills he learned in the immortal sect, Lin Feng set up a stall on the street, writing letters and drawing portraits for mortals to earn a living. Li'er helped the nearby residents to mend clothes and do housework.

However, their peaceful life did not last long. One day, Lin Feng and Li'er met a group of hooligans on the street. Seeing Li'er's beauty, these people had evil intentions.

"Young lady, come back with me and I will ensure that you have good food and drink." The leading gangster said with a lewd look on his face.

Lin Feng protected Li'er behind him, with a hint of coldness in his eyes, "You bunch of scoundrels, stop being so presumptuous!"

Seeing this, the gangsters burst into laughter. "Hey, kid, you're quite brave. Brothers, come on!"

Lin Feng was not afraid at all, and used his immortal magic to beat the gangsters in an instant. However, his action attracted the attention of the local government.

The government sent people to arrest Lin Feng and Li Er and put them in jail. In jail, Lin Feng and Li Er did not give up. They used magic to try to find a chance to escape.

Just then, the mysterious old man appeared.

"You two really cause me a lot of worry." The old man shook his head helplessly.

When Lin Feng and Li Er saw the old man, they felt as if they had seen a savior, "Senior, please save us."

The old man smiled and said, "Don't worry, I'm here."

The old man used his magical powers to rescue Lin Feng and Li Er from prison. However, their troubles did not end there. Their magic was exposed, which aroused the covetousness of some evil forces in the mortal world.

These evil forces began to search for the whereabouts of Lin Feng and Li'er, trying to get the secret of immortality from them. With the help of the old man, Lin Feng and Li'er fought desperate battles with these evil forces one after another.

In a fierce battle, Lin Feng was unfortunately seriously injured. Li Er was extremely worried and used all her magic power to heal Lin Feng.

"Brother Lin Feng, you must hold on." Tears welled up in Li'er's eyes.

Under Li'er's careful care, Lin Feng's injuries gradually improved. After this ordeal, their mental state was also greatly improved.

As time goes by, Lin Feng and Li'er's experience in the mortal world is gradually coming to an end. During this time, they have experienced the joys, sorrows, anger, and happiness of mortals, and have also experienced the test of life and death, which has deepened their understanding of the immortal way.

Finally, on a full-moon night, a strange light appeared in the sky. The old man told them that this was a signal to return to the Immortal Gate.

Lin Feng and Li Er smiled at each other and set out on the journey back to the Immortal Gate. They knew that this descent to the mortal world would be a valuable experience in their immortal journey and would also lay a solid foundation for their future cultivation.
