Three Kingdoms: The Cao Family's Tiger, Slaying Sima to Claim Zhen Ji

Cao Shu knows he is Cao Cao’s illegitimate son. To protect his biological father’s legacy, he wipes out the Sima clan from the start with the Tyrant System. When the court condemns him, he presents the curved-plow, solving the military food crisis, then captures Dong Cheng and exposes the plot behind the imperial edict hidden in a sash. After acquiring the Black-Armored Cavalry, he defeats Yuan Xi at the Battle of Dangyin. His strength, just shy of that of a Martial Saint, intimidates the warlords, and he becomes a key force helping Cao Cao unify the north.
