Zhu Yuntong

Biodata

Background / History

Transmigration and the succession crisis

Zhu Yuntong transmigrated into Zhu Biao’s third son around the time of his father’s death. From his inherited memories, he learned that Zhu Yunwen was about to be invested as imperial grandson and heir. His historical foreknowledge warned him that accepting this outcome would lead to confinement under Zhu Yunwen, further confinement under Zhu Di after the Jingnan Campaign, and eventual sudden death. These were futures he intended to avert, not events he had already experienced 1.

He entered court carrying a sword, wounded two guards who tried to stop him, and asked Zhu Yuanzhang to grant him death. He challenged Zhu Yunwen’s claim by emphasizing that Chang Shi had been Zhu Biao’s properly married principal wife, whereas Zhu Yunwen’s mother, Lü Shi, had originally been a concubine. He also raised suspicions about the deaths of Chang Shi and his eldest brother, Zhu Xiongying; Zhu Yuanzhang maintained that the earlier investigation had found no wrongdoing by Lü Shi 1 2.

When Lan Yu openly challenged the emperor, Zhu Yuntong slapped him and ordered him to kneel. The intervention both protected Lan Yu and demonstrated that Zhu Yuntong might be able to control the powerful general. He then argued that appointing Zhu Yunwen would endanger the Huaixi nobles and imperial princes. Zhu Yuanzhang put away the investiture decree, leaving the succession unsettled 2 3 4 5.

Afterward, Zhu Yuntong apologized to the wounded guards and requested medical treatment for them. In private discussions with his grandfather, he declared that he would compete if Zhu Yunwen remained the intended successor, but would accept a carefree princely life if the throne went to his second or third uncle 5 6.

Securing allies and protecting his sisters

Zhu Yuntong obtained pledges of support from Zhu Shuang, Zhu Gang, and Zhu Di by invoking their affection for his deceased parents and their shared concerns about Zhu Yunwen. Privately, he regarded Zhu Di as the greater threat and encouraged Zhu Shuang and Zhu Gang to watch him 11 12.

Within the Eastern Palace, Lü Shi controlled the servants and kept Zhu Yuntong and his four sisters on inadequate meals. Zhu Yuntong first took a lavish dinner intended for her household, distracting Zhu Yunjian with a paper airplane. The following morning, he brought his sisters to Zhu Yuanzhang, exposing their hunger and securing breakfast at the emperor’s table 10 13 14.

Zhu Yuanzhang refused Zhu Yuntong’s request to move out, but placed the four girls in Consort Guo’s care. Zhu Yuntong entrusted them to her and reassured Zhu Linghua that he would visit 16 17.

Lan Yu’s arrest and loyalty test

While helping Zhu Yuanzhang read memorials, Zhu Yuntong discovered a report accusing Lan Yu’s adopted son, Zhang Zhou, of sheltering a remnant of Hu Weiyong’s faction. He confronted Zhang Zhou, overcame resistance from Lan Yu’s household troops, and had Lan Yu detained at the Embroidered Guard headquarters under strict restrictions on access 20 25 26 27.

At the joint hearing, Lan Yu pledged unconditional obedience to Zhu Yuntong. When Zhu Yuanzhang instructed him to test that pledge, Zhu Yuntong ordered Lan Yu to kill Zhu Yunwen. Lan Yu brought his sword to Zhu Yunwen’s throat before Zhu Yuntong stopped him, establishing that the general would obey even an extraordinarily dangerous command 31 32.

Lan Yu survived but lost his title as Duke of Liang, retaining his military post. Zhu Yuanzhang counted the test as passed and assigned Zhu Yuntong a further task: divide the Huaixi military bloc rather than allow it to remain an unchecked source of power 35 36.

Executions and the reputation campaign

Zhu Yuntong took custody of Lan Yu’s sworn sons and private troops and brought them to the Skinning Temple. After their crimes were publicly announced, he personally killed Tang Da, Li Liangping, and Zhang Zhou with Jiang Jue’s saber. The Embroidered Guard executed the remaining condemned men 37 38.

These were his first killings across both lives. He suppressed fear, nervousness, and the urge to vomit because he believed losing composure would undermine the authority he was trying to establish 38.

Qi Tai and Zhu Yunwen subsequently used a classroom debate about Han Xin killing a woodcutter to portray him as cruel. Zhu Yuntong recognized the attempt and ended the argument with an ostensible concession rather than supplying more material for their attack. Rumors nevertheless spread outside the palace branding him bloodthirsty and comparing him to Zhu Yuanzhang 40 41 42 43.

Poisoning investigation

Zhu Yuntong became suspicious of incense sent by Lü Shi, believing it might contain a slow-acting poison. His later visit to the Imperial Medical Bureau revealed accumulated lead and mercury poisoning, prompting another attempt to leave the Eastern Palace 22 45 47.

Zhu Yuanzhang sealed the Eastern Palace and Imperial Food Service while investigators searched for the culprit. A cook confessed to poisoning Zhu Yuntong with “blue gold” and mercury, claiming revenge for past abuse by Zhu Biao. The suspected evidence in Zhu Yuntong’s quarters had disappeared, and the investigation produced no evidence establishing Lü Shi’s responsibility 47 49.

Zhu Yuntong requested that Liu Liu be spared from the emperor’s punishment of palace servants. He also used praise and teasing to ease Zhu Yuanzhang’s anger 49.

Appearance

• Thin, small, and physically weak: Zhu Yuanzhang notices that his build reflects the inadequate food provided in the Eastern Palace 14 36.
• Young-looking: Zhu Yuntong worries that his youth makes him appear unreliable to the military commanders 36.
• Poor stamina: He becomes exhausted after only a few steps when attempting to run; he later turns to broadcast calisthenics to strengthen himself 36 44.

Personality

Zhu Yuntong is audacious but calculating. His plea for death is a deliberate gamble based on Zhu Yuanzhang’s attachment to family, rather than a straightforward wish to die. He openly admits that he expects his grandfather not to kill him, while still fearing a beating 1 5.

He distinguishes between using powerful allies and depending on them. Although he wants Lan Yu and the Huaixi generals to survive, he understands that their military influence could threaten any young successor, including himself. He also refuses to trust imperial relatives solely because they profess familial affection 6 12 35.

His protection of his sisters is practical and affectionate: he secures food, promises them better futures, and arranges their care outside Lü Shi’s household. He likewise acknowledges his wrongdoing toward the guards injured during his entrance into court 5 10 14 17.

His ruthlessness is purposeful rather than effortless. He endorses executions for corrupt officials and personally kills condemned men to establish authority, but his first killings leave him frightened and nauseated. He later asks Zhu Yuanzhang not to kill too many people during the poisoning investigation 20 38 47.

With Zhu Yuanzhang, he is unusually informal and playful. He questions him directly, sits comfortably beside him, rejects performative dawn visits, and jokes about the emperor’s reputation for killing—behavior that helps their relationship become warmer 6 36 49.

• Uses knowledge of future conflict between Zhu Yunwen and the princes to undermine the proposed succession 3 4.

Relationships

• Zhu Biao — Deceased father. Zhu Yuntong’s claim rests on descent from his legitimate line 1 6.
• Chang Shi — Deceased mother, Crown Princess Jingyi, and legitimate daughter of the Prince of Kaiping. Zhu Yuntong questions the circumstances of her death in childbirth 1.
• Zhu Xiongying — Deceased full elder brother. His unexplained fatal illness forms part of Zhu Yuntong’s suspicions against Lü Shi and Zhu Yunwen 1 2.
