Hi I am looking for a BL novel I do not remember much of it. A boy transmigrates into a new world in which he a student of an academy. He is supposedly a student that is in a program of mechanical like robots. He and his group need to complete a test but are ambushed by their enemy I think they are called zerg. And he and his classmates band together together to try and save as many class mates as they can. He ends up catching the ml eye. I know it is not a lot of info but if someone can figure it out. Thank you in advance.
