I read a lot of transmigration novels, and most or almost all of them are MCs that cross into ancient times or the fantasy world? does not anyone go to modern times? rebirth novels its okay too
Lord of End of World - zombie apocalypse novel where MC came from cultivation world to modern world before the zombie apocalypse Reborn as a System - MC is modern guy but ML is originally from a cultivation world and goes world hopping with MC
reborn as a system (?) has something similar, except the one transmigration is the ancient gong and the shou is the system guide to raising my natural enemy (?) is from modern world to interstellar futuristic
