In the Age of Mythology, I Evolved into the World-Destroying Dragon

In White America, a cyborg code-named "Gun Demon" landed on the west coast, killed a million people in five minutes and then disappeared; In the South Ocean Islands, a black hole egg codenamed "Gravity Demon" hatches in the sky, allowing billions of tons of seawater and land to fly into space; In the capital of Elvi, a rotten giant codenamed "Zombie Demon" walks on the streets, turning the entire city into a doomsday purgatory of the living dead. In this era, humans have withdrawn from the top of their ecological niche and become food for the devils. Legend has it that all demons come from hell, but Bai Mo accidentally got a lizard clone in hell that can evolve infinitely... (Ps. The original name is I have a demon dragon clone in hell and cannot pass the trial...)
