Scene 1: A demon beast charges into his sickroom, he raises a rolling pin; result: the beast dies, he vomits, and Sun Erniang scolds, "Useless!" Scene 2: Qi Xuan steals rice, he doesn't kill him; result: half a bag of rice cooks into porridge for the whole pavilion, and the first grain rule is established. Scene 3: Refugees kneel outside the fence, he grits his teeth and takes them in.
