Chen Xiaoyun, an orphan from Guangzhou, China, once met a girl who looked remarkably like him. Before he could learn more about her, a deadly virus was unleashed around the globe.Humans turned into creatures straight out of video games and movies, and zombies and mutants roamed the streets with no one to stop them.From tanks to jockeys to even invisible zombies and mutated dogs. The mutations are just endless.“Why is there a zombie apocalypse just as I find my family? And why can I suddenly create things from thin air?”Will Xiaoyun survive the chaos with the new people he meets along the way? Will he use his newfound abilities to bring peace to a devastated world?Or perhaps he will just take another nap in the bed like a lazy pig——“Shut up. How am I supposed to do anything when you keep throwing women at me?”

The alien DNA is the best thing that has ever happened to Ye Shuang because the genetic optimization it offers has made her more beautiful, more formidable, and more brilliant.

But… why doesn’t this unknown alien species have a fixed s*x before adulthood‽ Alternating between both sexes every few days, why‽ For gender equality‽ Thankfully, she still has a chance to save herself. As long as she can settle down with a partner before full genetic assimilation, she’ll be able to carry on with her life as just one specific sex. For the sake of the perfect female body, all the men out there, beware!

But wait, what are all these women up to? Why are you all looking at me like a piece of meat‽ Halt, stop, don’t come any closer… What the hell‽
