Liu Huiben was an ordinary science and engineering college student. When he and his girlfriend from the agricultural college went to Shennongjia to collect plant samples, they encountered ball lightning. When he woke up, he found himself naked in Daikin in 1141. After going through all kinds of hardships, he returned to the Southern Song Dynasty and started a small business with the help of Queen Mother Wei. He thought he could be a wealthy country squire for the rest of his life, but was framed by Qin Hui. He was first sent to the frontier, and then demoted to the Jiyang Army. At this point, Liu Hui was completely disappointed with the Southern Song Dynasty court and recruited capable officials to separatize Hainan, determined to destroy the Song and Yuan Dynasties.
