Who is not a night watchman these days? This area is under my control! My name is Xu Qing! Delivering food in Daxia District, Jiangzhou City. Delivery during the day, but not at night! The drunken father left the mess to Xu Qing, leaving behind a unicorn beast and an iron halberd for subduing demons. From then on, he guarded a demon cave and restored peace to the Great Xia!
