Beyond the world known to humans, there is an extraterrestrial space, where a species that can enter the world line was born. They call themselves Wanderers.
Each wanderer will have an identity and the memory of his "original body" after entering the world line. And everyone has their own "superpowers".
Due to the strength of the Wanderers and their lack of fear of death (the reasons will be discussed later), some Wanderers become extremely arrogant, arrogant, and greedy, and their desires are infinitely magnified, eventually causing irreparable disasters and even destroying the world line.
In order to maintain the normal operation of the world line, the Extraterrestrial Space established the "Outer Space Administration", and some powerful wanderers became enforcers and executives, entering various abnormal world lines, arresting and executing wanderers who violated the "Ten Regulations of Extraterrestrial Space Wanderers".
As an official, Ye Ming entered the first world line in search of the lost "World Line Selector", but unexpectedly discovered a huge secret that had laid the foundation for the disaster many years ago - the other world. This seemed to be related to the Wanderer. In order to solve this disaster, Ye Ming and his team entered it every day to investigate.
But... Who is this high school classmate who is always following us!
You can't drive them away, you can't fight them.
Forget it, you understand me so well, then you can follow me if you want.
In the past, Ye Ming only cared about cats and the moon, but since he met this person, he began to like and care a lot. He would donate money to street singers, save little girls in danger, take into account whether others are sad, feel good because of seeing the clear sky, and feel sad for others who have lost their loved ones...
I don't know if you have any magical powers, but these memories in my mind tell me that I love you
Purpose: Humanity, faith and love, to discover the beauty of the world
