So I think I'm looking for two bl novel (idk maybe the could be the same novel). So iirc this two novel is a Quick Transmigration (I love novel full of arc). One novel have the arc with a storyline where its set in the future (interstellar). Where the MC woke up in a mech and he kind of became paralyze and then he met ML. ML took MC as a prisoner because their country like enemy. The MC woke up in a mech because he flee from his home country. His family was frame. MC is like a super genius technician. His enemy is a technician from the future iirc. The other novel i think is from wattpad idk. So one of the arc is also set in the future (futuristic setting) where there is apocalypse. One thing that I remember vividly is the MC survive in the apocalypse because some kind of wharehouse or supermarket. Land, water, and food is contaminated but its safe to eat from the supermarket. Because the supermarket make food automaticly and they kind of use a purified resource. Ps. English is not my first langauge
The first one is: Cannon Fodder Cheat System - Arc 8 - War of Mechanics (Ch. 96-113) As for the second... I'm sorry, I can't remember having read anything like that
