Liu Muhun, a young man from the 21st century, transformed into the Emperor of Great Xia, and was accidentally bound to a system for intercepting and killing time travellers. Only by killing time travelers of the same generation can he strengthen himself and stabilize the imperial power. He used the imperial power to set up layers of bait, and successively uncovered all kinds of passers-by in the harem, court, and army - eunuchs who tried to seize power, talented men who plagiarized poetry, counselors with systematic plans, and fanatics who coveted the harem. They were either subdued and used, or killed on the spot. He personally conquered the Yellow Turbans, used his strength to eradicate the aristocratic family, and then sent his troops north to fight against the alien traveler rebels. He fought decisively along the way, swept away all threats, firmly secured the throne, and restored the power of Great Xia.
