Modern youth Li Chenze travels through time to become the Great Han's Seventh Prince, King Jing'an. His biological mother was born of humble origins, possessing zero foundation in the imperial court. When heading to Jiangnan to investigate a case, he witnesses powerful noble families trampling on human lives with corruption running rampant, leaving commoners with nowhere to appeal their grievances. Faced with oppression and heavy obstruction from the powerful and noble, he bravely steps forward, enforces the law impartially, punishes evil and promotes good, and fights for justice for innocent commoners. From Jiangnan to the capital, he fears neither power nor death, investigates corruption, reforms administrative governance, protects the people's livelihood, and wins the support of millions with a purely sincere heart. Seeing his commendable loyalty and bravery, the emperor entrusts him with heavy responsibilities at the border.
