Liu Hua, a modern history enthusiast, accidentally traveled to the late Sui Dynasty and became an unknown boy with natural supernatural powers. He was bound to the "Wanjun Sign-in System" - daily sign-in can obtain rewards such as strength increase, magic weapon map, battle strategy, historical prophet, etc. Thanks to the blessing of the system, his power far exceeded the thirteen heroes of the Sui and Tang Dynasties, but he had to hide his edge step by step, and eventually became the pillar of the Sui Dynasty.
