Lin Che traveled to the Ming Dynasty during the Hongwu reign and became a tribute student participating in the imperial examination. Knowing how difficult it was to be an official in the Hongwu era, he longed to return to his previous life. However, the system demanded that he be executed by Zhu Yuanzhang to return to the modern era. So, in his imperial examination essay, Lin Che eloquently wrote "A Treatise on the Misleading Nature of the Imperial Examination System", aiming for death! Old Zhu was furious and threw Lin Che into prison, sentencing him to death in autumn. Thinking he would suffer, Lin Che befriended a second-generation nobleman in prison. He lectured him casually, not only avoiding suffering but also enjoying himself. "Mr. Lin, what is 'Capitalism'?" "Mr. Lin, can 'officials and gentry sharing responsibilities and taxes' really solve land annexation?" "Mr. Lin, what are 'commodity circulation' and 'equivalent exchange'?"
