I Have No Choice but to Use Zombies to Prove My Truth

System: "Damn it, if there wasn't another S13 system competing with me to delay the process, host you wouldn't have turned into a zombie." Xia Xia: "Ouch, ouch, ouch~ (These are useless, the magical system, please change it back to me quickly~)" System: "Host, what did you say? I don't understand. Wait... I'll load the zombie language." Xia Tian: "Ouch! (Stop talking nonsense, I just want to change back. I also want to find a girlfriend!)" System: "Host! Don't be stubborn! Love between children is a taboo in cultivating immortals. Even if you want to fall in love, you have to wait until you are successful in cultivating immortals!" "In order to prevent you, host, from being addicted to the love game, we will use the zombie form to prove the truth!" No, no, no, how can a human fall in love with a zombie?
