I'm an Apprentice Creator God

In this world, divine immortals and Buddhas, demons and monsters, the Old Ones, Outer Gods, anomalous containment objects... all take turns making an appearance. Humanity lives on ice floating in the sea, liable to melt at any moment, waiting for a savior to change its fate. An ordinary man acquires the Creator God System and raises a cat who claims to be the Demon Emperor. As he solves murder cases committed by inhuman beings and meets beautiful women from every corner of the world, he gradually makes his way to center stage.
