Super God Academy: I Joined Demon One from the Start

A pure Super God Academy fanfic: no fantasy cultivation, no immortal heroes, no crossovers, and no random transmigrations.

Have you ever read a Super God story where the protagonist enters Demon One?

Well, this is one.

(Transmigration + golden finger + slow pace + romance + comedy + harem)

The protagonist, Wang Xiao, transmigrates into the Super God world he knows inside and out. Will he serve his country, serve the gods, or become a demon? Or will he cast off all ties and live freely?
