Reincarnated into a World from 0 to 1

What if a person who has armed his mind with knowledge encounters a world that is completely opposite to his own knowledge? Can wisdom be applied everywhere? Should he stick to his own theory or integrate into the existing society? Does what most people think must be correct? When time and space change and theories turn upside down, will you change yourself or the world? This novel and its characters are purely fictitious.
