Wang Wei, a modern construction worker, unexpectedly transmigrates into the frail, sickly youngest son, Wang Sanniu, of a poor family of butchers. Every member of the family is as strong as an ox, but he alone is frail and delicate. To survive and help his family enjoy a better life, he begins his journey toward the imperial examinations, starting with identifying medicinal herbs to earn a living and learning to read and write. The humble young scholar wields his brush as a blade, while his family protects him with their strength. Amid human relationships and the turbulent currents of the world, he strives to rise above the tide and make his name in history.
