Reviewing History's Regrets, Starting with Wuhou's Northern Campaign

A historical recap System descends, reviewing the regrets of history across the ages! When the scene at Wuzhang Plains appears, everyone erupts in an uproar, then falls silent, tears streaming down their faces! The handsome eight-foot-tall man of old, the Longzhong scholar whose wisdom seemed almost demonic, now sits slumped in a wooden chair in a plain carriage. The wind stirs the sand, his long robe hangs empty, and the wooden chair seems far too large for him. Between two trails of cloudy tears, Zhuge Liang says, "I can no longer take the field to quell the rebels. Vast heavens, why have you treated me so unfairly?" Beneath the towering buildings in America, Li Hongzhang struggles to hold back his sorrow. "These buildings look very sturdy. Surely they can withstand any storm?" In a Southern Song prison, Yue Fei looks at the executioner before him and cries out with a bitter smile, "Heaven sees all! Heaven sees all!" On the platform at Shaqiu, the First Emperor lies ill inside his carriage. "The Great Qin must be placed in Fusu's hands! May China endure for all time." "If only I had ten thousand mansions," "Don't wait until your hair turns white, only to grieve in vain," "Before the expedition could succeed, the general died"... A review of five thousand years of history and its regrets: who is the greatest heartbreak in your eyes?
