Ming: Retire After Becoming Grand Secretary

Transmigrated as a low-ranking official, Lu Yuan witnesses a fellow transmigrator beaten to death by Zhu Yuanzhang. System activates: [Survival Rate 3%]. Safest path: play dumb, slack off, be invisible. Lu Yuan does so. But Zhu Yuanzhang thinks otherwise: 'This man is deep and must be a pillar of the Great Ming!' Liu Bowen: 'Your Majesty, he's too honest.' Zhu: 'No, he's wise as if foolish!' So Lu Yuan is dragged into investigations, forced to be a double agent, and promoted against his will. Lu Yuan internally: 'I just want to lie low until the end, stop overthinking!' System: 'Congratulations, host becomes Grand Secretary, survival rate 99%.' Lu Yuan: 'Can I retire now?' Zhu Yuanzhang: 'The crown prince hasn't ascended yet, work another fifty years.'
