Hello, dear reader, based on the plot you described, I highly recommend the novel,"I am a Painter in the Apocalypse"! The protagonist Shang Ming had a Quantum Magic Brush in the apocalypse. He could draw anything he wanted. This magic brush was simply a divine artifact in the apocalypse! He could draw immortal robots, mutated pets, kinetic skeletons, and so on. It was enough to help Shang Ming find hope in the apocalypse. This novel was a sci-fi space-doomsday crisis genre. The female protagonist, Shang Ming, was a strong woman. There was no CP, but the pace was fast and compact, which was very attractive. I hope you like this novel~
