I, the King of a Subjugated Country, the System Asks Me to Liquidate History

Murong Xiang, the late Emperor of Yan who passed through the Five Hus and Sixteen Kingdoms, started out in a dead end - his capital was besieged by the Northern Wei Dynasty, and there was a food shortage and people died of starvation all over the place. The powerful ministers hoarded food in the hope that he would die early. Even the history books crucify him: in the first month of his reign, he was addicted to bloodshed and subjugated the country, and died without a complete body. What's even more deceptive is that it is bound to the "Dynasty Liquidation System" and instead of sending gold fingers, it collects debts: "Recover the 100,000 stones of grain secretly hidden by Murong Lin within 3 days and distribute it to the people, otherwise the life points will be reset!" "Rescue the 5,000 Han people kidnapped by the Northern Wei Dynasty within 7 days, otherwise a historical killing move will be triggered!" In order to survive, I can only play the role of a "crazy tyrant": On the surface, I behead corrupt officials, attack enemy countries, and weld to death a murderous device; secretly, I use the cleared grain and grass to open a porridge shed, rely on the Mo Dao Formation rewarded by the system to strengthen the army, and use historical information to poach the corners of the Northern Wei Dynasty. The refugees called me Living Bodhisattva, and the nobles recognized me as the Lord of Ming. Even Tuoba Gui of the Northern Wei Dynasty was confused: "Why is this Murong Xiang different from the idiot in the history books?" It wasn't until I stood at the top of Pingcheng City and looked at the surrendered Hu and Han people that I understood: the so-called liquidation was never about wiping the old dynasty's butt, but was asking me to personally change the "script of national subjugation" into the beginning of a prosperous era for the Hu and Han family! (Graduate student in the history department + anti-routine system + unpopular and troubled times, no Holy Mother, intensive fun, watch the king of the subjugated country take on history!)
