Well I don't know what to say but maybe I can narrating some part.
Firstly mc is spaceship with intelligence soul and bro ran away because the human want to dismantling his body (battleship) cuz of his body was made of various rare metal and they think it's not cost effective after the test . Then bro ran into blackhole and ended up on earth and bro made a clone to earth and stuck there cuz of meteorite smash the spacecraft bro was in and then bro ended up as a toy car .bro become stronger from toy car to a motorcycle ,sport car , transformer , fighter plane and etc . Damn I'm too lazy to write more so just read it yourself
I knew you guys would look at review first before reading so I just tell you directly. In early plot mc foundation is solid and when protagonist come only to be bullied my villain mc because heroine already reserved by villain mc and some even become his women . When the plot start bro only need to harvest villain point and the rest of middle plot ? I’m too lazy to write more so just read it your self 😁
