Arc 2Lan Yu and the Poisoning
Zhu Yuntong navigated Lan Yu’s arrest, earned authority in the army by executing Lan Yu’s adopted sons, and outmaneuvered Zhu Yunwen’s attempt to portray him as cruel. After discovering he had been poisoned, Zhu Yuntong pushed Zhu Yuanzhang to investigate and secured permission to move out of the Eastern Palace, though Lü Shi’s involvement remained uncertain.
- Zhu Yuntong arrested Lan Yu, but after Lan Yu’s followers blocked the escort, he released Lan Yu’s bonds and ordered him to bring them back into line.
- At a court hearing, Zhu Yuntong tested Lan Yu’s loyalty by ordering him to attack Zhu Yunwen, then pleaded with Zhu Yuanzhang to spare Lan Yu when officials accused him of treason.
- Zhu Yuanzhang kept Lan Yu alive but ordered Zhu Yuntong to kill Lan Yu’s adopted sons and win the Huai-Western Generals’ support, so Zhu Yuntong executed the sons and released Lan Yu.
- Zhu Yunwen and Qi Tai tried to cast Zhu Yuntong as cruel, but Zhu Yuntong’s poem impressed Zhu Yuanzhang and left Zhu Yunwen overshadowed.
- At the Imperial Medical Bureau, Xu Shu diagnosed Zhu Yuntong with lead and mercury poisoning, prompting Zhu Yuanzhang to seal the Eastern Palace and investigate its servants and the Imperial Food Service.
- Jiang Jue reported that Zhu Yuntong’s cook had poisoned him with blue gold and mercury, and Zhu Yuanzhang ordered the cook and others punished while sparing Liu Liu at Zhu Yuntong’s request.
- Xu Xingzu admitted responsibility for the poisoning and received a reduced punishment, while Zhu Yuntong continued to suspect Lü Shi and asked to leave the Eastern Palace.
- Zhu Yuanzhang ordered two houses beside the Imperial College prepared for Zhu Yuntong and Zhu Yunwen, while the evidence remained insufficient to determine whether Lü Shi was involved.
