The richest man in modern times, Gongsun Jie, accidentally traveled through time and became the father of the Zhao Kingdom. In order to save Zhao State, he bought grain at a high price, but was framed by the treacherous minister Guo Kai and deposed by the coward Zhao Qian. King Yingzheng of Qin, who remembered his old kindness, invited him to join the Qin Dynasty as a gift from six cities. Gongsun Jie was worshiped as the prime minister of the left and the Taifu. He used his advanced knowledge to promote papermaking, improve weapons, and promote agriculture and mulberry trees, which greatly helped Qin's national power. Later, he cleverly used counterintuitive tactics to drive a wedge between Zhao Qian and Li Mu, secretly rescued Li Mu and recruited him into Qin. In the end, Gongsun Jie led the Qin army to Handan, rejected Zhao's peace proposal, and asked Zhao Qian to kneel down and surrender. This not only avenged the past, but also helped Qin start its hegemony of unifying the six countries.
