Li Hanjiang, who traveled through time and became a royal guard of the Scarlet Flame Empire, wanted to avoid trouble and live a low-key life, but accidentally activated the system. Starting from a small flag in a remote county town, he worked with his associates to eliminate mountain bandits, thoroughly investigate the conspiracy of officials and bandits, and uncover the secrets behind the Moon Worship Sect. With his extraordinary resourcefulness and fierce methods, he has been steadily promoted in the whirlpool of temples and rivers and lakes, using the law as an edge to punish evil and protect the peace of the country. When the power struggle gradually emerged, Li Hanjiang established his position as a royal guard and walked out on his own right path amidst the turmoil.
