The Shadow Lord of the Apocalypse

The end of the world is coming, and 90% of humans have been infected into zombies. The remaining 10% of the lucky ones, if they want to survive in this crisis-ridden apocalypse, must face challenges such as zombies, alien beasts, and disasters... As one of the 10% lucky ones, Shu Mu summoned a shadow servant at the beginning, and from then on he lived a peaceful and upgrading life. Bored? How about raising two pets? Dragon? No, that's just my little lizard that can spit fire! Piranha? No, I just raised a little flower demon. It doesn't eat people, but it eats zombies. What? Will being scratched or bitten by a zombie become infected? "It's okay, the shadow servants will deal with them." What? Is there a zombie outbreak? "The Sea of ​​Man-eating Flowers will take care of them. You can also add dragon flame baptism. By the way, the shadow servant is massaging me, so I don't have time." (Single female protagonist or no female protagonist, the female who appears in the early stage has nothing to do with the male protagonist, please feel free to eat.)
