Although Qin Ji did not hesitate to bite his tongue and commit suicide on the spot, he refused to confess who was behind him to murder Mei Er, but the glance he subconsciously looked at the east before he died, Yang Guang still saw it in his eyes, and a suspicion arose in his heart, but because there was no evidence, it was inconvenient to continue to make more conjectures, so he ordered someone to carry Qin Ji's body down and bury him, and released Zhao Geng, who was blamed by Qin Ji, from the prison, and returned to the Jin Palace.

When he returned to the Jin Palace, he still didn't see Pei Yun coming back from Shangshu Province, and Yang Guang was anxious to find him to discuss what was the intention of someone to instruct Qin Ji to murder Mei Er, so he ordered Guo Yan to personally go to Shangshu Province to invite Pei Yun back to the mansion to discuss matters.

After Guo Yan received the order to leave, Yang Guangzheng wanted to order Li Jing to personally take someone to investigate Qin Ji's interactions with people during his lifetime, and wanted to find clues about the person who instructed him to murder Mei Er, but at this time, he got a report that a school captain who had stayed in Daxingshan Temple on Pei Yun's order to investigate the case of Gu Sheng's rebellion was now outside the palace gate, claiming that he had something important to ask to see Pei Yun.

When Yang Guang heard the report, he ordered Li Jing not to leave for the time being, and sent the captain to the palace to see him.

After a while, I saw that the captain walked into the main hall of the palace with a young man who looked like a miscellaneous servant, and saw that Yang Guang had finished the ceremony, and the young man who followed behind him reported: "Lord, when Gu Sheng was a miscellaneous servant in Daxingshan Temple, he lived in the same room with him, and when he asked him at the end of the day, he told the general an unusual thing, and the general thought that it might be related to the person who instructed Gu Sheng to rebel, so he took him to the palace to explain to Pei Duji's room. ”

Yang Guang looked at the young man, waiting for him to come forward and report to him.

The young man was not stage frightened, and stepped forward to bow to Yang Guangshen, and said, "The little one's name is Zhang Xiaoqi, and Gu Sheng lived in the same room with the little one when he was doing a miscellaneous job in Daxingshan Temple. Today, the military master found the little one, and asked the little one about Gu Sheng's situation in the Daxingshan Temple, the little one remembered this matter, and maybe it would be useful for the court to investigate the case: I remember that it was not long after Gu Sheng went to the Daxingshan Temple to do miscellaneous labor, and it was the time of the fourth watch, and the little one got up at night on the way back to the house, and vaguely heard the sound of sweeping the floor from outside the courtyard that was only one wall away from the small accommodation room, thinking that Gu Sheng had just come to the temple not long ago, in order to behave well, he got up so early to clean the temple, so he thought about asking him to come back and sleep a little longer, did not go back to the house, and walked straight out of the temple through the side door. However, as soon as the little one walked out of the side door of the temple, the shadow saw Gu Sheng sweeping the floor while talking to a man in white, and when he heard the sound of the small footsteps, Gu Sheng immediately separated from the man in white and walked over to the little one. Lord Wang, you also know that although the incense of Daxingshan Temple is extremely prosperous, no one will come to the temple to worship the Buddha, and as soon as the man in white saw me, he immediately turned his head and left, which naturally aroused a small suspicion, so he ignored Gu Sheng's dissuasion, called the man loudly, walked in front of him, and interrogated him. The man seemed to be very unhappy that the little one stopped him, and ignored the little one, but Gu Sheng ran over to explain to him that this person was not a native of Chang'an, and he got up early in the morning and found the wrong way, so he came here by mistake, and he had already shown the way to this person. Because Gu Sheng said this, the little one didn't think much about it at the time, so he let the man in white leave, but now that he thinks about it, Gu Sheng's reaction that morning seems to be too enthusiastic......"

"So, did you see the face of the man in white?" Yang Guang listened to Zhang Xiaoqi's words, perked up, and asked.

Zhang Xiaoqi nodded and recalled: "The man in white is about thirty years old, more than eight feet tall, and he looks pretty white, but he was very cold to the little one at that time, and ignored it, oh, when the little one walked in front of him, he seemed to be very vigilant, and his right hand was always on his waist, as if he was carrying a weapon......

"Have you not seen him since that day?"

Zhang Xiaoqi shook his head without thinking.

"If you were to describe the man in white in detail, would you be able to do it?" Li Jing suddenly interjected and asked Zhang Xiaoqi.

Zhang Xiaoqi nodded at Li Jing firmly.

"Lord Wang, the last general would like to ask Yang Xuangan, the eldest son of the Duke of Yue, to help him, and according to Zhang Xiaoqi's description, paint a portrait of the man in white, so that he can find the man in white according to the map." Li Jing clenched his fists and said to Yang Guang.

Yang Guang thought about it, it seemed that there was indeed no better way to find this mysterious man in white from the hundreds of thousands of residents in Chang'an City besides what Li Jing said, so he nodded and agreed.

Li Jing got Yang Guang's permission, and personally went to the Yueguo Mansion to invite Yang Xuangan, and asked Zhang Xiaoqizai to carefully explain the appearance of the man in white to Yang Xuangan, and asked Yang Xuangan to draw a portrait of the man in white according to Zhang Xiaoqi's description. Yang Xuangan previously said in Bingzhou that he had successfully painted a portrait of Liu Jushi and helped Gao Ying quickly find Liu Jushi's body, although this time he could only paint a portrait of the man in white according to Zhang Xiaoqi's description, Yang Xuangan also cheered up very energetically, and tirelessly changed seven or eight drafts successively, until the evening of the same day, Zhang Xiaoqi was satisfied, pointed to the last draft of Yang Xuangan's revision and said to Yang Guang: "Lord Wang, it's him." ”

Out of prudence, Yang Guang ordered the lieutenant and Zhang Xiaoqi to be temporarily placed in the palace, and personally accompanied Yang Xuangan to draw more than a dozen portraits of the white-clothed people overnight according to the draft approved by Zhang Xiaoqi, and the next day he ordered people to hang and post them in the twelve city gates of Chang'an City, and awarded a thousand "five emperors" to arrest the white-clothed people.

At the same time, Guo Yan, who was ordered to go to the Shangshu Provincial Government Office to ask Pei Yun, brought back a handwritten letter written by Gao Ying to Yang Guang, Gao Ying said in the letter that when he checked the case file, he found that there were still many doubts in the cat ghost case that Pei Yun had been ordered to preside over the investigation, and had suggested to the emperor that he planned to thoroughly investigate the case, in order to facilitate the rapid and thorough investigation of the cat ghost case, Pei Yun was still entrusted to preside over the investigation, in order to avoid the leakage of the case, Pei Yun was temporarily left in Shangshu Province, and Pei Yun was released back to the Jin Dynasty after the cat ghost case was investigated, and apologized to Yang Guang for the inconvenience caused to Yang Guang.

Yang Guang didn't mind Gao Ying's practice of cutting off first and then playing, and almost forcibly leaving Pei Yun in Shangshu Province, after all, Gao Ying was not only the first assistant in the court, but also assisted his father Yang Jian to open the Great Sui Dynasty for many years, pacified the rebellion between the north and the south, and created the prosperous era of the emperor, and has always been deeply respected and trusted by his father and mother, if there is no sufficient reason, he will never leave Pei Yunqiang in Shangshu Province, but Yang Guang has heard Pei Yun report to him in person about the investigation of the cat ghost case. I vaguely heard that Pei Yun's words alluded to the fact that the cat ghost case might involve the East Palace, and he acquiesced to Pei Yun's approach of investigating Xu Ani and ending the case out of consideration to avoid direct conflict with his eldest brother Yang Yong.
