Has the Tyrant of the Troubled Times Corrected His Evil Ways Today?

A female college student majoring in history traveled through time and became an amnesiac girl who was pushed to block a knife by her brother when she was in China. She disguised herself as a man to escape, accidentally picked up a ten-year-old Han military genius, but accidentally entered the battlefield of the Jie tribe tyrant and became a prisoner. In order to survive, in the name of "Han Military Advisor", she used modern knowledge to help the tyrant solve the food shortage and stop the butcher's knife, becoming a smart and annoying existence in his eyes. He regards the Jie people as wolves and the Han people as sheep, and wants to use the blood of the Jie people to improve everything; but she wants to be the knife that protects the sheep in this troubled world. Food shortages, suspicions, and ruptures followed one after another. The young men picked up in the past grew up to be famous anti-Hu generals and ran counter to her. The Han ministers of the tyrant also rebelled, and the Han-Hu confrontation intensified. When she sacrificed her life for a brief check and balance in the troubled times and returned to modern times, she realized that he would repent of her madness and massacre the Jie clan. Later, he finally met his military advisor again on the streets of the real world.
