A modern supply-chain risk-control manager wakes up as Li Jinglong, son of a famed Ming general. From the start, Zhu Xiongying is gravely ill, the Jinyiwei have sealed the gates, Zhu Yuanzhang is personally interrogating him, and everyone in the hall is waiting for him to take the blame. Fortunately, a straight-laced Doubao has come along in his mind. It can organize historical records and assess risks, but it cannot make decisions for him. Whether saving the imperial grandson, his father, or the crown prince, Li Jinglong just wants to stay away from military power and keep himself safe. But the harder he tries to prove he cannot command troops, the more Zhu Yuanzhang believes he is up to the task. Then the Prince of Yan arrives at Jinchuan Gate, and Doubao reminds him again: according to historical records, you are not suited to command a large army. Li Jinglong looks at the city gate and replies with just one sentence: This time, it stays shut.
