The Sixth Tribulation of the Emperor

There is no innate cultivation system. All cultivation paths, realms, and powers were created, named, and perfected by the protagonist Su Jin. He is the only ancestor of the world's cultivation civilization. There is no heroine, no fetters, and no holy mother. He is determined to seize power, create a path, and reach the top. He is extremely cool, decisive in killing, and works step by step. He uses a mortal body to create an emperor's path, and he becomes supreme after six calamities.
