Genshin Impact.

Under the guidance of the old man, Lin Feng and Li Er embarked on the journey of descending to the mortal world to experience tribulations. This tribulation is crucial to their immortal journey, and it is related to whether they can comprehend the great way and ascend to a higher realm in the future.

They plunged into the human world, Lin Feng became an ordinary scholar, and Li'er became his personal maid. At first, their lives in the world were relatively peaceful. Lin Feng studied hard every day, and Li'er took good care of him. However, as time went by, Lin Feng gradually discovered that this tribulation was not as simple as he had imagined.

In the human world, anime culture prevails, and a mysterious force called "second dimension" quietly emerges. This force distorts people's cognition and thoughts, causing the human world to fall into chaos. Lin Feng realizes that this "second dimension" power may be the key to their tribulation this time.

One day, Lin Feng ran into a mysterious old man on the street. The old man was in ragged clothes, but his eyes revealed a deep wisdom. He held Lin Feng and whispered, "Young man, this two-dimensional world is a catastrophe. If you want to survive this catastrophe, you must understand the true meaning of it." After that, the old man disappeared.

Lin Feng fell into deep thought, and he began to study the "two-dimensional" culture in depth. He found that the "two-dimensional" world was full of various fantasy stories and characters, which seemed to have their own life and will. In the process of exploration, Lin Feng gradually became addicted to it and forgot his identity as an immortal and his mission to experience disasters.

Seeing Lin Feng so obsessed, Li Er was extremely anxious. She tried to wake Lin Feng up, but was repeatedly rebuked by him. "What do you know? This two-dimensional world contains great truths. I must understand the secrets." Lin Feng roared.

Li'er was heartbroken. She didn't understand why Lin Feng, who was once devoted to Taoism, became like this. However, she did not give up. She decided to find a way to survive this disaster on her own.

Li'er asked around and learned that in a deep mountain, there was a hidden master who might know how to solve the "second dimension" calamity. She set out on a journey to the deep mountain despite the dangers.

After several days of trekking, Li'er finally found the master. The master told her that the calamity of the "second dimension" was the calamity of the inner demon, and only by sticking to one's original heart can one survive this calamity. Li'er suddenly realized it, she thanked the master and hurried back.

When Li'er returned to Lin Feng, Lin Feng had completely fallen into the world of the "second dimension" and could not extricate himself. Li'er burst into tears, she hugged Lin Feng tightly and said, "Brother Lin Feng, wake up, we can't be trapped by this inner demon."

Lin Feng gradually regained some clarity under Li'er's call. He looked at Li'er, feeling full of guilt. "Li'er, I was wrong. I shouldn't have indulged in it." Lin Feng said.

With Li'er's help, Lin Feng began to re-examine his inner self and tried to get rid of the temptation of the "secondary" world. They practiced and explored together, trying to find a way to break this calamity.

After countless days and nights of hard work, Lin Feng finally had an epiphany during a practice. He understood that the "two-dimensional" world was nothing but an illusion, and the true path was to stick to one's heart and follow nature.

Lin Feng opened his eyes, and a strong aura emanated from his body. He successfully survived the "second dimension" calamity and realized the true meaning of Tao. Li'er looked at Lin Feng with a gratified smile on her face.

At this moment, a roar was heard in the sky. The old man appeared in front of them. He looked at Lin Feng with satisfaction and said, "Yes, you finally realized the truth in the calamity. You have gained a lot from this calamity."

Lin Feng and Li'er smiled at each other. They knew that after this ordeal, their path to immortality would be smoother.
