Episode 6 recap: The Curse Comes True: Song Ci Launches an Investigation.

Yancheng is now completely sealed off. Lord Wei informed them that it was likely due to a frightening curse. Lord Wei also mentioned the incident involving General Li's murder. Suddenly, someone approached and informed them that the Mongolian envoy had also died, and the manner of death was extremely peculiar—a sword pierced through the chest, killing him instantly. Song Ci quickly rushed to the scene to conduct a thorough investigation. Once again, it appeared to be a locked-room murder. Some believe it must be the curse of Wanyan Mu, a curse known to be practiced by the Jin Dynasty.

The Mongolian envoy naturally felt aggrieved, as they were constantly being accused. Song Ci questioned two young ladies nearby who had initially accompanied the Mongolian envoy. The envoy had expressed a desire to go out for some fresh air, and they had been waiting for his return, but he never showed up. Li Zi Fang was also investigating nearby. Song Ci planned to identify the culprit as soon as possible. The Mongolian representatives promised to give them seven days to solve the case. Song Ci also asked Lord Wei to clean up the crime scene, as they would perform an autopsy the following day.

The remaining individuals gathered in the main hall, providing explanations for their whereabouts during the period when the Mongolian envoy was killed. They all had sufficient alibis. Bai Xue Yan accidentally fell asleep in her room, but fortunately, Qin'er, an attendant from the inn, promptly woke her up when she noticed Bai Xue Yan unconscious. However, Bai Xue Yan completely forgot how she fell asleep.

Qin'er mentioned that she and her brother were planning to close down the inn soon. They were unsure when the imperial court would truly launch the Northern Expedition, which was necessary for seeking revenge. Bai Xue Yan offered to comfort her when the time came. Song Ci mentioned several methods of death associated with the curse of Wanyan Mu. Currently, both General Li and the envoy from the Western Xia Empire were killed in the same manner. The Mongolian envoy, on the other hand, was killed differently. This suggests that a series of murders will likely follow. The Jin Dynasty envoy grew uneasy, as three envoys remained, and the killer would undoubtedly strike again.

At this moment, Alan, as a guard from the Jin Dynasty, naturally arrived since his task was to protect the envoys. However, since the situation had not yet escalated, nobody knew what would happen. The Jin Dynasty envoys initially considered leaving, but Lord Wei stated that if they left now, their suspicions would not be cleared.

Song Ci also informed everyone that the culprit was among them. Bai Xue Yan, having offended someone in this matter, believed that someone was deliberately framing the Jin Dynasty using the curse. Song Ci proposed that they would find the real culprit within seven days, and everyone agreed. However, if they failed to do so within seven days, the blame would naturally fall on the Song Dynasty.

Li Zi Fang felt that Song Ci's request to solve the case within seven days was indeed too tight of a timeframe. He was very worried that they wouldn't be able to find the real culprit. The next day, Grand Tutor Han Wei learned about the major incident in Yanhui City and hurriedly arrived at the scene. After arriving, he first learned about the entire case and, upon hearing that it might be Wanyan Mu's curse, began preparing to investigate the matter.

Zhao Xiao Liu from the Six Doors followed Song Ci and the group in their investigation. However, Han Wei had never heard of a person named Zhao Xiao Liu from the Six Doors. But upon hearing Song Ci's name, he found the matter intriguing. Song Ci first examined the body, as the living wouldn't tell the truth, but envoys would never lie.

Song Ci first extracted the solution from the envoy's stomach contents, which was done to facilitate the investigation into whether the deceased had ingested any poisonous substances. The common characteristic of the two victims was that they didn't struggle much before death, which made Song Ci suspect that they might have consumed poisonous food during their lifetime.

Zhao Xiao Liu couldn't bear it anymore and had to run outside to vomit. Bai Xue Yan, who was actually Han Wei's adopted daughter, learned that another murder had occurred in the capital after she left. Song Ci and the other two went to the military camp to investigate General Li's death. General Li's younger brother knelt on the ground and insisted that they must find the real culprit. Song Ci entered the tent, and nothing in the layout had been disturbed.

Li Zi Fang also looked through some official documents in the vicinity, but General Li's younger brother quickly stopped him and informed him that those were highly important documents that couldn't be casually touched. Zhao Xiao Liu accidentally knocked over a nearby scripture book and was harshly scolded by Song Ci. Song Ci questioned General Li's younger brother about his whereabouts on the night of the incident. He claimed that he was in his room drinking due to being upset about things and that the Mongolian subordinates had seen him, as they had sat together and chatted.

Song Ci also obtained important information that Alan had left the inn on that evening.
