Liu Shi'an transmigrates to the Great Chu dynasty and becomes a butcher.
He discovers that the original owner became a butcher after being framed by fellow officers in the Guard Against Martial Forces.
Looking at his own greasy appearance, he thinks he'll be stuck slaughtering pigs for the rest of his life.
Then he awakens the Butcher System and gains a variety of skills from pigs.
Active skill: Slaughter pigs to absorb their vitality and restore your health.
Passive skill: Pig's Retaliation. Whenever someone injures you, you enter a berserk state and your power increases tenfold!
Active skill: Pig's Sense of Smell. A slight sniff lets you identify an enemy's scent, even their killing intent.
So he takes up his butcher's knife and returns to the Guard Against Martial Forces.
He can't stand the court oppressing the people and preying on the common folk, so he sets the constables straight!
He can't stand his superiors colluding with bandits for personal gain, so he sets them straight too!
Wherever he goes, he takes down corrupt officials from top to bottom.
In the end, he earns countless titles:
"Liu One Slash"
"The Strongest Butcher"
"The Court's Honey Badger"
"Great Chu's God of War"
A deputy centurion has more influence than the emperor.
