Luo Mancheng is a genius inventor of Xindi. When he was young, he relied on ancient blueprints to rub a hand-made purifier to protect Xindi from the invasion of mutant plants. Not only that, he is also an avid mecha enthusiast, but his status as an omega is destined to prevent him from driving mechas.
By chance, he received an invitation to participate in academic activities on Planet Blue, the center of the galaxy. Although it was the first time he left his hometown, the deputy captain of Star Guardian fell in love with him at first sight and was even willing to hide his identity to protect him secretly.
The deeper they get along, the more strange Luo Mancheng feels. The scientific research report that everyone avoids talking about, the star core stolen from Star Blue ten years ago... All of this seems to be related to the vice-captain.
But when he asked, the other party asked: Teacher, don't you remember me?
What the hell, where did his own student appear from?
Purpose: Protecting the environment starts with me
