Apocalyptic Fusion: Pick up the Girl with a Red Umbrella at the Beginning

The seven apocalypse collided suddenly and turned into a bloody purgatory. Rules and evil ghosts whisper in the shadows, and strange beasts from the mountains and seas trample on the earth. The fallen brave man held up the blood-stained holy sword, and mechanical natural disasters weaved a death formation. When others were struggling to survive under the claws of natural enemies, I had turned their strength into food for my evolution. From supernatural powers to physical training, from trickery to technological weapons... I am a walking natural disaster! (Seven fused worlds: the supernatural world, the ghost world, the ancient world, the tyrant world, the deep sea world, the brave world, and the machine abuse world)
