Three Kingdoms: Beginning with Engagement in the Zhen Family

(This book does not contain gunpowder, aircraft, cannons and other black technologies. Readers who are very strict about history should read the Three Kingdoms.) Time travel and become Liu He, son of Liu Yu. The system says that it can be activated only by engagement, so make five. He intercepted famous ministers and powerful generals from all walks of life. When Xianbei troops came to the city, Liu Yu became terminally ill and died soon after. Liu He took over the army on behalf of his father and defeated Xianbei twice, beheading thousands of people before returning. Using water power forging, cold forging technology, and using the knowledge given by the system, he returned to the Central Plains from the abandoned frontier county. Troubled times are coming, and I, Liu He, will be the one who determines the fate of the country. In this life, I will serve the great man for another four hundred years. The places where the horses' hooves tread are all Han soil, and the flags pointing to are all Han officials.
