Lu Heng transmigrates into the body of a disgraced official's son, banished to the frontier wastelands. All he inherits are three thousand refugees, seven days' worth of rations, and a stretch of saline-alkali land nobody believes can be farmed.
The frontier army is waiting for grain, powerful local families have their eyes on the water, the court cares only about collecting taxes, and the northern tribes are watching from the shadows.
Everyone says Baishi Garrison is a death trap, a place of exile where no one can survive.
But with his farming expertise, Lu Heng repairs old canals, reclaims barren fields, organizes the refugees, builds granaries and workshops, and trains troops to protect the harvest.
Starting with nothing but a hoe, he manages to grow the first storehouse of grain in the war-torn frontier, and plants the seeds of a way forward for the north.
Years later, as the lords of the realm fight over land and grain, they finally realize that the small-time farming official they exiled has already turned his place of banishment into the empire's granary.
