Capital tycoon Yuwen Zhao transmigrates as Yuwen Chengdu's younger brother. When his beloved, battle-hardened elder brother is on the verge of a gruesome death, he activates the System and starts ruthlessly milking the great clans: he makes a fortune stockpiling grain and short-selling, then opens factories to feed the refugees! When the Wagang Army and Li Shimin come knocking, he uses modern business-war tactics to stockpile grain, manufacture weapons, and recruit skilled craftsmen and soldiers. He stands firm against the elite Tiance Cavalry, vowing to pull the Yuwen family back from the brink of annihilation and pave an emperor's road with money!
