If one day something strange happens and all things are destroyed, and you can live with your relatives and friends, or you can die for the sake of the world, what choice will you make? Not an AI article! This is the author's first work. This article tells the story of Li Muran who traveled to the Xuantian Realm due to a space rift and practiced at the same time as Meng Yanzhou, a young boy on the earth, and finally uncovered a strange conspiracy. This article is written in two lines of the story of Li Muran and Meng Yanzhou. It is a novel writing method. I hope everyone will come and appreciate it. If there are any bad things, point them out to me and I will correct them. I hope everyone will like my work.
