As soon as Lu Zheng and Li Wu returned to the Zhenfu Division, Jin Yiwei came to report, and Si Xiangnan interrogated the rebellious party and got hundreds of names. In the school grounds, Si Xiangnan handed over the confession to Lu Zheng, saying that he ordered people to search the house of the Water Transport Envoy of the Gyeonggi Metropolitan Water Transport Department last night. Lu Zheng came to the palace and handed over the confession to Yuan Zhongdao. Yuan Zhongdao said that he was fighting, and who should be used after all the people were taken away. Lu Zheng thought that once the old people left, there would be new ones. Yuan Zhongdao said that he had to think about this matter carefully.
In front of the palace's Dengwen Drum, Li Wu said that all the censors knelt here before dawn, and they should pay attention to their bodies, otherwise they would easily miss important events, and asked the royal guards to bring futons and tea. The leader took out the blood letter written by the villagers of Zhaojia Village for Wang Kegong. When he stood up, Li Wu stepped forward to help him, stole the blood book in his sleeve, and said that he had to report to the officer first.
Zhen Fusi, Li Wu came to Lu Yulin. Lu Yulin thought that they took out the blood letter to bite Lu Zheng back. With Lu Zheng's temper, he would definitely reverse the case for Wang Kegong. If Wang Kegong wasn't a rebellious sage, he shouldn't be sentenced to death, and Lu Zheng shouldn't be pardoned either. As he said that, Lu Yulin couldn't help covering his face and weeping, fearing that no one could save Lu Zheng. At this time, Li Wu asked Lu Yulin what he should do, and Lu Yulin told Li Wu that the blood letter must be suppressed no matter what, and Lu Zheng must not be allowed to reverse the case for Wang Kegong.
In the room of the mansion, seeing Lu Zheng insisting on asking about the affairs of the palace, Li Wu deceived him, and the palace officials went to Dengwengu to make trouble because they had not paid their salaries for two years. Seeing that Lu Zheng became suspicious again, Li Wu hurriedly asked him to teach him how to write. Lu Zheng taught Li Wu by hand, and Li Wu cherished the note and put it in the pouch on his waist.
In the middle of the night, when it was raining heavily, Li Wu looked at more than 30 people kneeling in Zhao's yard with their fingers cut off. Jin Yiwei arrested the patriarch, and Li Wu burned the blood book in front of him. The head of the Zhao family shouted that Wang Kegong saved himself and the whole Zhao family in the imperial prison in the year of Hongwu. Jin Yiwei covered the head of the patriarch. Li Wu apologized secretly and cut off his fingers.
In a trance, Li Wu came to the restaurant in Ji'e Lane, ordered a jug of wine and began to drink heavily. Li Wu told Song Tianyi that he also wanted to save a very important person, and hoped that he could help him. Song Tianyi took the fish lock from the table and secretly handed it to Zhang Junqing.
Jin Yiwei told Lu Zheng that he had found Shannong at the market. When Lu Zheng arrived, he found that Jin Yiwei had fallen to the ground. Seeing Ye Bushou with a ghost face, Lu Zheng quickly drew his sword and moved forward, and they fought Ye Bushou. During the fight, the sachet fell from Ye Bushou's body, and Ye Bushou fled in a hurry. Lu Zheng smelled the scent of the sachet and thought about it. At Zhang Ji's silk and satin shop, Li Wu saw that Zhang Junqing had returned to his room, so he searched around, and actually let him come to the secret room of the bell tower.
Yuan Zhongdao was very satisfied with Li Wu's handling of the Zhao family's blood book, but he was dissatisfied that Li Wu reminded Song Tianyi and tampered with his sachet. Yuan Zhongdao told Li Wu that he had already made arrangements. Song Tianyi died in Lu Zheng's hands as a ghost face. There is no doubt that Zheng will die. Li Wu hurriedly begged Yuan Zhongdao to save Lu Zheng's life. Yuan Zhongdao expressed that he had to dispel Lu Zheng's suspicion of Zhang Junqing, and asked him to lead Lu Zheng to kill Song Tianyi himself.
On the other side, Lu Zheng has arrived at Zhangji Silk Shop. When Lu Zheng broke in, Li Wu said that he wanted to make a winter coat because Zhang Junqing had it tailored. Lu Zheng asked Zhang Junqing to recognize the sachet worn by Dai Guimianyebu. Zhang Junqing admitted that the flower was indeed only available to him. Li Wu helped explain that Zhang Junqing had bought and sold the flower. Lu Zheng believed the two and apologized for his misunderstanding of Zhang Junqing. .
Li Wu came to the Lantern Festival and saw Song Tianyi disguised as a porter. Song Tianyi told Li Wu where he lived, drank and left. Li Wu bought a river lantern, and after writing Professor Lu Zheng's words "Together with horses, no doubts and no failures" written on it, he and Lu Zheng set off the river lantern together.
In the middle of the night, with heavy rain, the two came to Song Tianyi's residence in Ji'e Lane and found that the building was empty. On the way the two left, Lu Zheng suddenly called Song Tianyi, who was pretending to be a watchman, to inquire. Just as Song Tianyi was about to leave, he actually exposed his identity as a ghost. Lu Zheng looked at his weapon and recognized him as the murderer who killed Wang Kegong and Xie Kengran. The two fought. Li Wu stepped forward to block Lu Zheng's sword, and Lu Zheng successfully killed Song Tianyi. Lu Zheng left with Li Wu on his back, while Song Tianyi watched the sachet in his hand die.
On the cruise ship, his subordinates told Li Dongfang that Song Tianyi, the traitor who intended to murder him, had died. Li Dongfang walked into the cabin and saw Shu Tang who was eating and drinking. Shu Tang told him that Zhang Junqing saved him.
