[Demon Master + High Martial Arts + Invincible + Cool Writing + Relaxing + Funny + Passionate + New Theme] If you are asked to be a teacher, all your subordinates will be world-destroying monsters? Yan Xuan traveled through time and became a teacher. But under his command are all terrifying demon students. Face the demon students causing trouble. Yan Xuan suddenly awakens the "teaching you how to be a human being" system! Students causing trouble = parents being struck by lightning! Nine-tailed fox cheating? Qingqiu Patriarch's tail hair was shaved off by the calamity! The beast boss skipped class? The ferocious beast Qiongqi tap dances in the thunder tribulation! The gold-eating beast wastes food? Ancestor Taotie's hair was burnt bald by lightning! What the teacher can't control, the ancestor does! The teacher only cares about the ancestor! ....... Yan Xuan: "If you continue to cause trouble, I will let your whole family dance in a thunderstorm!" Yan Xuan waved his hand and let the legendary and terrifying demon ancestor come out to educate his descendants. From now on: Zhulong uses the World-Destroying Dragon Flame to grill BBQ (the heat is accurate to milliseconds) Representatives from the Corpse King Section control 100,000 puppets to help lonely elderly people harvest autumn crops. The gold-eating beast ate up all the school's leftovers and won the title of "Compact Disc Pacesetter" ... The originally unruly ferocious beasts and monsters. They were all educated by Yan Xuan to be good demons who promoted civilization and established new trends. Many years later. Because Yan Xuan secretly cultivated the world-destroying demon Heaven is angry and punishes—— The thirty-third heaven was suddenly enveloped by tens of thousands of thunder tribulations! The sealed world-destroying demons roared collectively: "Whoever dares to touch Teacher Yan, I will tear this broken heaven apart first!" ... ▼Click to watch the online parenting group of Thunder Tribulation Survival Parents Group▼
