How Is the Demon King Made?

The more I read it, the more I think it's a novel about the immortal king's reskin.

Nice setting. The characters in it are always reminiscent of Albedo in Overlord. I'll collect them first.

By the way, let me ask, according to the way it works, which school of magic is here (rules system, philosophy system, dimensional system)? For example, using magic to make fire, the rule system uses rules to make particles move at high speed, generate heat through friction, etc., And there is even no air in high and deep places. It can start a fire; the philosophy department changes the surrounding environment and physical parameters to make fire, such as the ignition point of a certain substance (this school generally consumes belief in merit and luck, not magic power); the dimensional system redefines the rules by changing the spatial structure, making the matter of making fire in this case feasible.
