Luo Feng, accompanied by the Sector Beast Morosa, had passed through reincarnation and arrived at the Land of Origin....

For others, apocalypse means running away, killing zombies and upgrading.

For Shi Lingxi, it means not only running away, fighting zombies, and upgrading but also public display of affection!!!

It’s not that he is weird, but that he has a weird system that requires him and his forcibly bound target to reach a certain love index of sprinkling dogfood. In order to survive in the apocalypse days, he can’t not do it.

Shi Lingxi: Dear Lou Yuan, come here, muah~~

Lou Yuan: Muah~~

Shi Lingxi: What’s wrong with showing my love for Lou Yuan? Hmph.

This is a sweet story where Xiao shou seduces the Xiao gong and they sprinkle dog-food together.
