Quickly Travel, I Leave Traces When I Come and Go in Other People's Worlds

System 010 is a ghost-like existence under the door of the quick travel department. It comes and goes without a trace. Because it cannot take the host to travel to many different worlds like other systems, it can be said to have no sense of existence. Other systems can leave many traces with the host, but it can only be admired and imagined by the audience... Until Cha Sheng, the department head, arrived, the world of 101 finally began to change... Cha Sheng: It just so happens that my promotion reward is an energy ball that can repair your flaws. Are you willing to absorb it? The condition is that you can only have one host, me. 010: I obey, Master Cha Sheng! Let's set off to another world now! I can't wait to leave our own chapter! In a different world, the girl who stretches out her hands in the school playground, the general who protects the country with socks hidden in the cupboard, the mischievous male protagonist who cultivates immortality but cannot fly up the cliff, the journey of loss in the end of the world, the magical isolation molecular membrane of the interstellar... Cha Sheng: Then let's set out to save the world! People in another world: I feel lucky countless times just to meet you.
