The Sacred Dragon's Evil Sovereign

Zhang Fan is a peerless assassin, born proud and unyielding, but in truth a kindhearted man who only kills those who deserve it. A single kiss sends him transmigrating to another world, where he possesses the body of a useless wastrel and suffers endless bullying and mockery. When that wastrel suddenly becomes a genius, everyone is left gaping, if they even have glasses to gape through. He climbs to the peak, points his sword at the heavens, stands above all living things, and roars loud enough to shake the world!
