“Mr. Zhang, it is said that you often make zombies work overtime without pay, is that true?” Zhang Ye, enraged, snatched the microphone that was pushed to his mouth and said righteously: “Who said that?” “I’ll sue them for defamation!” “Someone’s defaming me, you know!” As he spoke, he turned and grabbed a zombie, “Did I force you?” The zombie, silent, just went “Ugh ahhhh—” Zhang Ye immediately said, “See!
