I Have the Inheritance of Li Cunxiao in Three Kingdoms

The modern soul Liu Feng traveled through time and became Liu Feng, the young concubine of Liu Yan, the shepherd of Yizhou (no historical record, fictional identity). Just as Liu Yan was about to enter Shu, Liu Feng asked to stay in the Central Plains on the grounds that he was "frail and needed to rest", secretly activating the "Late Han Dynasty Hegemony System". Gift package for newbies: Inheriting Li Cunxiao's military heritage, 1,000 cubic meters of system space (no living animals allowed), Liu Feng will not tell anyone about the system even if he kills him. This is Liu Feng's biggest secret, not even his father can tell him, "Basic Military Training Minutes". - Chapter 11-30: Liu Feng used his prophetic knowledge of history to convince Liu Yan that "in the future he could help his father stabilize Yizhou", and through Liu Yan's connections and financial resources, he purchased the fictitious position of "Chenliu Prefect" (Chenliu belonged to Yanzhou at this time, which was relatively stable before the Yellow Turban Rebellion). Although Liu Yan had doubts, he cherished his young son and secretly left 500 private soldiers and food to support him.
