Traveling Through Another World, I Am Zhenjun Ziwei

Yun Kai, a migrant worker, died of exhaustion, but traveled to a new urban world with supernatural powers. In this city with supernatural powers, Yun Kai survived the Tomb of Ten Thousand Swords, entered the supernatural department, broke through the strange deserted building, and visited the ancient cemetery... "Ziwei! True Lord Ziwei!", "Why do you call me True Lord Ziwei?", "How do you know that I want to be called True Lord Ziwei after I become an immortal?" "Because, this is what luck tells us!"... Yun Kai has never been here, but he was known by several immortals. This must not be a coincidence... "You must be Mr. Yun Yuan, the beginning of all changes in luck." "You said that yin and yang are the beginning of everything, and yin and yang implies transformation! This, this, what does this mean?"... How does Yun Kai travel through time, why does he travel through time, and what are the changes in yin and yang? Let us see the truth in the story! (If there is anything you can learn from the story, please share it! Thank you!)
