Lin Ping'an, a struggling game designer, accidentally "compiled" himself into Ping'an County at the end of the Great Zhou dynasty while trying to fix a bug. It's a hellhole besieged in turn by 30,000 refugees, 300 bandits, and 10,000 barbarian cavalrymen.
Luckily, he has System No. 9527 from the Myriad Worlds Ping'an Neighborhood Committee. Its core KPI is "save lives in exchange for Peace Points."
One bag of refined salt = 3,000 bandits surrender,
One cement formula = an iron wall built in seven days,
One AK-47 blueprint = ... Forget it, he can't actually build that.
He makes promises, trades for grain, and recruits talent, turning refugees into laborers, bandits into farmers, and a barbarian princess into a financial consultant (though they haven't recognized each other yet).
His motto: "There's a problem with this mechanic, but I can fix it!"
So while other county magistrates are still begging the imperial court for disaster relief,
Lin Ping'an is already using "tree-bark porridge + refined-salt KPI assessments" to get the refugees hauling bricks;
while other prefects are still recruiting troops,
he's already using "cement walls + black-powder land mines" to make the Blackwind Stockade chief kneel and call him Dad;
while other military governors are still worrying about the Iron Wolf Tribe marching south,
he's already plotting to use refined salt to trick the barbarian cavalry into becoming the "Ping'an County Foreign Mercenary Corps"...
From county magistrate to city lord, and then to a warlord in a chaotic age,
others conquer the land with soldiers and horses; he does it with game management, wild schemes, and a silver tongue that can talk the dead back to life.
But the System tells him: "Your ex-girlfriend transmigrated too. She's a barbarian princess, her memories are sealed, and you need 100 affinity to unlock them."
Lin Ping'an: "...Who wrote this plot? Come out and take a beating!"
