[I have flown a mecha before, so I am not writing randomly, nor am I taking it for granted. ]
[There are many female protagonists, not the Virgin. The protagonist is decent, but not the traditional image of greatness and uprightness. He will not be kidnapped by morality and will not be selfless. ]
Jiang Miyue is a medical student, but has never learned any medical knowledge and does not know how to treat diseases.
Just because a brand new 'virus' has come to the earth from the outside, animals or humans infected by this 'virus' will turn into man-eating monsters.
Jiang Miyue's mission is to use the mecha as a scalpel to physically save these monsters with "viruses".
But as Jiang Miyue continued to eliminate monsters and become stronger, he discovered that there were two races that came to the earth. The kings of the two races were twin sisters, who were in charge of "power" and "power" respectively. However, they could not gain complete "power" by devouring their own sisters, so they had to find other ways... And Jiang Miyue was involved in this whirlpool.
"It's okay to save people, just get some medicine and cure the disease!"
"As long as I stand here, no one can take away my power."
