Once you bite it, the world is yours.
When the doomsday comes, Tian Yi, who becomes a zombie, gets a biting system, which is a bit different.
"What, you said that as long as I bite someone, I will have all the abilities of that person. If I bite a girl, that girl will become mine."
"Mikasa, don't run away. Just let me bite you, just one bite. Hey, Himiragi Yukina, haven't I already bit you? Why do you want me to bite you? I already said I'm not a vampire, ah! Second Miss, why are you biting me? Don't think that if you bite me, I will bite you back."
