Time and space turn, spiritual qi revival arrives, and the secrets of immortality reappear. When all this descends upon the modern city, will it bring disaster or hope?

He looked left and right, but he was the tallest one there. Even lying down would not help. Since he could not stay out of it, he would hold up the sky by himself!
