Being Chased by Zombies at the Beginning: This System Is Really Bad

"I almost went through reincarnation again just now..." Coming to this world where zombies are rampant and spiritual energy is revived, Ye Xuan often deeply suspects that he is the most unlucky time traveler in history. He was chased by zombies as soon as he woke up. "System, system, are you there? I'm being hunted!" "Hey, hey, I'm playing mahjong. If the signal doesn't work, I'll tell you later." "What's the reward for today's mission? System?" "Yes... I'm defaulting on it for now because I lost your reward spirit sword while playing mahjong..." However, despite the unreliable system, Ye Xuan still fought wits and courage with the evil as a little expert in killing zombies and ghosts. Just kidding, what does it have to do with me, a serious person, if the system is so stupid?
