Yang Guang saw that the topic was a little far, so he waved his hand and said, "Let's discuss the collusion between the north and the south first, and we want to plot rebellion." Gao Yuan's order for Pan Dan to carry a letter to Gao Qinglian, coupled with Li Jinglai's report of Gu Sheng, who pretended to be Liu Jushi, sneaked outside the border to lobby the Turks, all kinds of signs show that the north and the south are gradually converging, rushing to it, what good strategies do you have to deal with it? ”

Pei Yun replied: "Gu Sheng sneaked from Chang'an to lobby the Turks, and soon after, his party went north from Jiankang to join him, which shows that there must be a secret channel between Chang'an and Jiangnan to transmit news, so that the remnants of the 'Wild Goose's Nest' hidden in the two places can cooperate with the action at any time, and according to Li Jing's inference, since Jiankang went north to the customs, it is possible that it was Zhang Zhongjian himself who killed Gu Sheng, which shows that the person who hid in Chang'an and instructed Gu Sheng to go out of the customs should be above Zhang Zhongjian. If this is the case, the lower officials think that they should start at the same time from Chang'an, Jiangnan, and Guanwai to thoroughly investigate the case. Moreover, under the current circumstances, it seems inappropriate to suggest that the imperial court should use troops against Goguryeo. ”

Yang Guang asked Li Jing thoughtfully: "I just heard you mention that your father appointed Feng Lun to envoy Goguryeo and return Yan Thirteen, I don't know if you ever learned the result of Feng Lun's envoy to Goguryeo when you set off from Bingzhou?" ”

Li Jing replied: "When the last general left Bingzhou, although Feng Lun did not return from Liaodong, it was reported that Feng Lun's envoy to Goguryeo this time was similar to the situation of the last general's envoy to the Turks with General Changsun, and the progress was relatively smooth. ”

"Well, even so, I still have to remind my father in the last chapter that I must be more vigilant against Goguryeo." Yang Guang paused, and then discussed with Pei Yun, "At present, the Juntian system has not yet been widely implemented in all parts of Jiangnan, although this king intends to return to Chang'an to face his father and emperor to collude with the north and south, and want to be unfavorable to my Great Sui, but he can't pull away for a while, it's better to be like this, Chongzhi, you will temporarily hand over the mission to preside over the investigation of the remnants of the 'Wild Goose's Nest' in Jiangnan to Jin Cai, and you will return to Chang'an in person with the previous chapter that this king gave to the imperial court. As for the investigation of Zhang Zhongjian No. 1 Middle School outside the Guan, I will write to Gao Ying, asking him to assign competent people to start working at the same time, what do you think? ”

Pei Yun reminded Yang Guangdao: "Chang'an, Jiangnan, and Guanwai are carrying out an investigation at the same time, and they must exchange information at any time and unify their command. ”

"You take the first step, and after the situation in Jiangnan remains stable and the Juntian system is generally implemented in the six counties and thirty states in the south of the Yangtze River, this king should ask for a return to the court, and then discuss this matter." Yang Guang had his own considerations because of the situation in the Chang'an Dynasty that Li Hun reported to him not long ago, and did not adopt Pei Yun's suggestion.

"Since the prince is unwilling to take charge of the general investigation of the case, if after the lower official returns to Chang'an, it is found that the person who instructed Gu Sheng to rebel has a noble identity, and it is not appropriate for the lower official to directly report to the saint, what should he do?" Pei Yun asked pointedly.

"Are you referring to Uncle Chen?" Yang Guang simply picked out the words and asked Pei Yundao.

"According to the expectations of the lower officials, now in Chang'an, this person is the only one who can instruct Gu Sheng." Pei Yun nodded and replied, "But Xia Guan was originally an official in the Southern Chen Dynasty, and Chen Shubao's identity is extremely special, if it is found out in the future that he is the mastermind behind the scenes, it seems that it is not appropriate to directly explain the identity of the lower official to the saint, and I hope that the prince will understand." ”

"Uncle Chen?" Hearing Pei Yun say this, Yang Guang couldn't help but see Chen Shubao's excessively drunk, slightly puffy pale face in front of his eyes, and subconsciously shook his head and questioned, "If he had cheered up earlier, Nan Chen would not have died in his hands, how could he only think of using the 'Goose's Nest' to seek restoration after the death of the country?" Chongzhi, don't care about what you just said, after you return to Beijing, if you really find out that the mastermind behind the scenes is Chen Shubao, then this king will go to his father to make it clear. ”

Yang Guang made a clear statement, Pei Yun had nothing to say, so he had to take the order, and that night he drafted a recital to the imperial court on behalf of Yang Guang in the county guard office, and the next day after Yang Guang saw it, he resigned to Yang Advertisement, set off with the recital, and went straight back to Chang'an to meet Yang Jian.

Under the protection of Li Hun, Li Jing, and Guo Yan, Yang Guang went deep into the eastern part of Zhejiang to inspect the people for nearly a month, until Zhang Heng sent someone to report to Yang Guangyu, and the imperial court adopted Yang Guang's suggestion, and more than 30 Juntian prison envoys selected from various places to implement the Juntian system in Jiangnan had arrived in Guangling, and were waiting for Yang Guang's reception.

After returning to Guangling and meeting with these 30 people, Yang Guang specially ordered Zhang Heng to equip each of them with a secretary office, two account offices, and 10 guards, and sent them to various places in Jiangnan to take up their posts, urging the local governments to earnestly implement the system and promptly report to the problems and difficulties encountered in the process of implementing the system so that they could be properly resolved in a timely manner.

It is said that Pei Yun traveled thousands of miles from eastern Zhejiang to return to the imperial capital Chang'an with Yang Guang's concert, and wanted to submit the chapter through Zhongshu Province and ask to see Yang Jian, the ancestor of Sui, but he did not want to be told by the officials of Zhongshu Province on duty that he had to meet the prince Yang Yong first, and only after clarifying the reason for returning to Beijing could he see the emperor.

Although Pei Yun did not participate in Zhang Heng and Yuwenshu's conspiracy to promote Yang Guang to enter the East Palace, and also understood the reason why Yang Guang was ordered to return to the court last time, he heard that the officials of Zhongshu Province wanted to go to the prince Yang Yong to explain the reason for returning to Beijing first, and he was a little reluctant in his heart, and he was thinking about finding another way to get past Yang Yong and directly present Yang Guang's recital to Yang Jian, the ancestor of Sui, but saw that the official of Zhongshu Province on duty had introduced himself to the subordinates of the East Palace who were responsible for guiding the officials in Zhongshu Province to meet the prince. I had no choice but to follow the man to the East Palace to meet the crown prince Yang Yong.

At that time, Changsun Sheng had already sent an envoy to return to the Turkic court, and made it clear to Yang Jian that Gu Sheng had actually lobbied the Turks to raise troops to attack Sui under the guise of Liu Jushi, and reported the news that Liu Jushi and his person had been killed by unknown traitors, so that the truth of the case of Liu Jushi's rebellion, which caused a sensation in Chang'an, was revealed to the world, and Li Jing, Yang Xuangan, and other generals and eunuchs who were implicated in this case also recovered their reputation and freedom.

Although the crown prince Yang Yong can be said to have found nothing in the investigation of Liu Jushi's rebellion, he was appreciated by Yang Jian, the ancestor of Sui, who believed that Yang Yong was not afraid of offending people and could loyally run errands for the imperial court.

The crown prince Yang Yong firmly seized this opportunity and instructed Zhongshu Province that all vassal kings and officials returning to the court from other places, except those who were transferred back by special order of the emperor, must first go to the East Palace to explain to him the reason for returning to Beijing, and then he would decide whether to arrange for this official to meet the emperor according to the situation.
