Doomsday My Phone Mutated

Doomsday is coming, and zombies are rampant.Survival has become the most difficult thing, and as an ordinary otaku, Li Yi is even more difficult to do.
Fortunately, my mobile phone has mutated, and I can improve my strength as long as I play games.
Super Mary, get a physique boost, clear the level, and a gene-enhancing potion?Run cool every day, get a speed boost, and still have god-level parkour skills after customs clearance? .........
When others were still worried about food, Li Yi played a few games and became invincible.Killing zombies, occupying land is king, raising a beautiful woman, and living a leisurely life like a fairy.
"Is the Zombie King very powerful? When I finish cleaning this dungeon, I will hack you to death!"
