Fusion of the Heavens? I Became the Devil

Have you ever received a text message from another you? At the end of the world, Zhou Cheng from the parallel world sent a text message: "Your world will be destroyed in three days. Countless dimensions merge and countless civilizations invade. Your world is in danger..." Faced with the reminder from me in the so-called player world, Zhou Cheng said don't panic... That means don't panic! I have the player system, I have the Dimensional Rubik's Cube, I have the Hand of God... Whatever dimensional civilization comes into my hands, it will definitely belong to me... What? Demon Slayer Squad? Dead Rising? Black magic invasion? Weird creature? … Ding! After learning the Breath of Fire, Kagura, the God of Fire! Bite! After learning black magic, Avada gnaws on the big melon! Bite! The space rules are analyzed and the mirror collapses! Bite! The avenue of time has been understood, time goes back... As a bug analyzer walking in the world, what if the world is full of things? When a creature as powerful as a god saw Zhou Cheng, he finally had to kneel down and scream: Demon King, spare your life!
