Qin Mo, a graduate student at the University of Political Science and Law, died suddenly and traveled through time, becoming the Jianwen Emperor Zhu Yunwen who was usurped by Zhu Di. In a desperate situation, he bound to the Chinese legal system and used modern rule of law as a weapon to issue a cross-time and space summons to Zhu Di. He used the rule of law to break the imperial power and use the law to determine the country. He opened courts, tried corrupt officials, froze the treasury, and judged the emperor. He disintegrated Zhu Di's regime with a piece of paper and implemented a new rule of law in the Ming Dynasty. From the deposed emperor on the run to the head of the rule of law, he relied not on swords but on laws, creating a new era of rule of law in the Ming Dynasty, and staged a legal counterattack legend that overturned history.
