I recommend that you do not grow a crop.
It will be the biggest shit you will do with the novel, technology should never be combined with cultivation in this way.
If you sent him to another technological universe or directly to the land of this one, it would not open so much problem, but when people see a transformers fanfic what they want are robots fighting and technology not cultivation.
this is pretty cool.
a lil moth tho.
these nine chapters could easily become 90 if you make it more story-like. (more interesting system function, dealing with becoming a robot, extra tid bits or story arcs) everything is just so fast.
theoretically if he copies a human body he would get a human form and this could allow the development of meridians and dantain but it will be made of mechanical wires or circuits for meridians and his core could be his dantain
