Everyone in the capital knows that Pei Che, the third young master of the Duke of Dingguo's household, is a useless wastrel who does nothing but cockfight, chase birds, eat, drink, and have fun.
To earn him some military merit, his father kicks him off to the northern frontier.
But the moment Pei Che arrives at Shuofeng Pass, he's dumbfounded.
Wasn't he supposed to be sent there for an easy promotion? Why are barbarian cavalry already right on top of him?!
Fortunately, in his previous life he was an elite special forces tactical instructor. He knows military strategy, can build firearms, and is an expert at all sorts of underhanded tricks.
Just wanting a good night's sleep, he casually upgrades the city's defenses, and the enemy army charges straight into a death trap.
Just wanting a roast whole lamb, he takes his men out for a picnic beyond the pass and casually wipes out 3,000 elite northern cavalry.
Pei Che: "I'm really not a god of war! I just want to coast for three months and go back to the capital!"
Frontier soldiers: "The young marshal has kept his true abilities hidden. We swear to follow him to the death!"
The ministers: "This young man has the makings of a pillar of state!"
Later, the northern barbarians tremble at the mention of Pei, and the whole realm knows the Great Jing has produced a young god of war.
But when Pei Che sees the mountain of military reports piled on his desk, he completely breaks down.
"Seriously, I just wanted to be a wastrel. How did I end up becoming a pillar of state?!"
