Zhou Gan, a social animal, transformed into a human in the Water Margin, but was tricked into Liangshan by the "children's song system". He threw his handkerchief when others were angry with him. When the enemy attacked the city, he sang "Two Tigers" and became the most evil military advisor in Liangshan. Watch modern thinking collide with classical heroes, use performance evaluation to rectify copycats, use PPT to fool Song Huizong, and even negotiate a super contract for the "Shandong Loyalty Army" for the brothers - obey the instructions but not propaganda, be autonomous but not pay for food, and professionally fight against gold. When a children's song turns into a charge on the battlefield, can this outrageous army find a new way to survive on the eve of Jingkang?
