The Supreme Overlord's Earth Reunion

Kael, a man once meant to defend Earth from a monstrous invasion, was instead flung into a cultivation universe. For 100,000 years, he clawed his way to unimaginable heights, transcending every realm and becoming the Supreme Overlord, capable of reshaping multiverses with a mere thought. Boredom, a formidable foe even for him, now compels him to return. Earth, ravaged by the very monsters he escaped, is a shadow of its former self. Kael, with his god-like power that alters the fundamental rules of existence, faces a world that has forgotten him and a war that never ended. Can a being who controls creation itself find purpose in merely saving a world he inadvertently abandoned? His cold demeanor masks a deeper struggle.
