Lingzhi was suddenly sluggish, Ye Hongyi asked Juechen to do it. After Juechen's divination, she thought that there were evil spirits and filthy things in the palace, which caused the ganoderma to become slumped and found an abnormality in the northwest corner. Ye Hongyi ordered Ye Junqing to go to the alchemy room to investigate the matter thoroughly. When Ye Hongyi came to the alchemy room, he found that the table was full of fake medicines, and Gong-gong Liu and Gong-gong Li, who were responsible for the supply of medicinal materials, had been taken to the prison.
An Bingshan is torturing Liu Gonggong. Ye Hongyi suspects that An Bingshan's refining medicine is faulty, and reprimands him for doing things badly, fines him a year's salary and hits another 20 board. After Yao Suluan knew about it, he asked An Bingshan to deal with the aftermath to prevent Ye Hongyi from detecting it. It turned out that in order to refine the pill, An Bingshan took the palace lady to try the medicine. Most of the palace ladies who were tested for the drug were dead and a large number. An Bingshan said that he would deal with it without leaving a trace.
In the middle of the night, An Bingshan wanted to destroy the corpse and threw the palace maid who tested the medicine into the dry well. Ye Junqing caught him right there. After verification by the corpse, these palace maids were indeed poisoned by the medicine. Ye Hongyi became furious when he learned about it, but rejected Li Guofu recommended by Ye Junqing, and instead asked Zhang Shaoqing to hear the case. As a result, Juechen was named the new state affairs of Da Chu.
Yao Mowan came to the prison in a black robe and interrogated An Bingshan in person. An Bingshan knew that he had offended Yao Mowan and his life would be hard to save, so he determined to bury him with his back. He told all of Dou Shiming's activities, and Zhang Shaoqing recorded it nearby. It turned out that Dou Shiming privately used black gunpowder from the army to make alchemy at An Bingshan. An Bingshan helped Dou Shiming introduce river officials from all over the country. Dou Shiming sold black gunpowder for profit and used the antique business to transfer dirty money.
Yao Mowan mentioned the death of Yao Moxin again. She thought it was a problem with the anti-fetal medicine that An Bingshan sent, but he did not expect that the instigator behind all this was actually Ye Hongyi. The reason was that Yao Moxin was too capable. Repeatedly intervening in government affairs, and being ambiguous with Ye Junqing, rumors arose in the palace, so when Yao Moxin was pregnant, Ye Junqing publicly thought about the unborn Zhonger before going to the battlefield, and Ye Hongyi was suspicious and thought Zhonger. The origin of the blood was unknown, and she didn't want the child in her womb, so he ordered An Bingshan to put the gum in Yao Moxin's fetal medicine, which also confirmed Yao Mowan's guess.
Yao Suluan meets Ye Hongyi, and Yao Suluan accidentally overheard Zhang Shaoqing's confession to interrogate An Bingshan while delivering him mint soup. After reading the confession, Ye Hongyi became angry and ordered Zhang Shaoqing to lead his troops to Yao Mansion for a thorough investigation. Dou Shiming knew that he could not hide, and he deliberately delayed the time and asked Dou Xianglan to hide the account book. Zhang Shaoqing had no choice but to find the evidence of Dou Shiming's crime.
Just as Ye Hongyi was unable to do anything, Ye Junqing brought a box of gold, which was the evidence of Dou Shiming selling black powder. But Ye Hongyi didn't reward Ye Junqing. On the contrary, because he was too strong, the dike was jealous of him. Ye Hongyi felt a little unhappy and asked Qianmian to investigate the case thoroughly.
Ye Junqing knew that the ledger was the key, and asked Han Jinyi to steal the ledger and bring it to Zhang Shaoqing. Dou Shiming knew that his death was inevitable, and with Thresh's evidence, Qian Mian had already sent someone to stop Dou Shiming. Dou Shiming and An Bingshan were convicted and beheaded for selling arms to show the public. It was also to warn the corrupt officials of the court, to deter them, and to warn them that they would be punished twice if they committed another crime. Later, Ye Hongyi didn't want the internal conflict in the court to affect Da Chu Jiangshan, and threw the list of corrupt officials into the brazier.
