Guo Song heard the news that Li Zhengji died violently, this kind of violent death is generally an unnatural death, poisoned or assassinated, he may have been killed by his son, but it is more likely that he was killed by Yang Yu.

Yang Yu told him that one of the most important tasks for him to go to Ziqing to serve as the hall master was to assassinate Li Zhengji, if Li Zhengji was killed by Yang Yu, would he be safe now? Will it be wiped out by the Hidden Sword Pavilion?

Although Guo Song assassinated Tian Shenyu and Li Lingyao, and also captured Lu Sigong, they were different from the feudal towns, they were still courtiers.

The feudal town is a semi-independent kingdom recognized by the imperial court, and the assassination of the head of the feudal town means that the assassination of the king will cause extremely serious political consequences, which will lead to the complete independence of the feudal town, or trigger a large-scale revenge of the feudal town, and dozens of important ministers will be stabbed to death in one day, and even the royal family will be assassinated.

Everyone understands this, so they dare not easily use the method of assassination against the feudal town, and even if they use it, they must not admit it, and they must also exterminate the assassin in time.

This is what Guo Song is worried about, if Li Zhengji is assassinated by Yang Yu, then the Hidden Sword Pavilion will definitely kill all the participants.

It was precisely because of this understanding that Guo Song was worried about Yang Yu.

Guo Song saw that Xiao Yuniang had misunderstood herself, so she smiled and said, "I didn't mean that you were spying on me, but I just wanted to inquire about some things about the Hidden Sword Pavilion, do you have any way to contact the people inside." ”

Xiao Yu Niang thought for a while and said, "I can be contacted, but I have to go to Chang'an." ”

Guo Song nodded, "Then it's hard for you to go to Chang'an!" ”

Xiao Yuniang scratched her head, "The key is what did Gongzi ask me to do in Chang'an?" ”

Guo Song smiled dumbly and said to her: "You go and inquire about Yang Yu's news, you know Yang Yu!" ”

"I know, Ziqing Hall Master."

Guo Song thought for a while and said, "By the way, bring me a letter to Senior Brother Zhang Lei." ”

"I see, pack up and go."

Xiao Yuniang went down, Guo Song remembered something, Gongsun Auntie told him that if the imperial court did not send a supervising army, then the Tibetan Sword Pavilion would definitely send someone to monitor the local military leaders, and there would be no exception.

The Son of Heaven did not send a prison army to himself, so it was obvious that the Hidden Sword Pavilion would definitely send someone to monitor him.

Just like Yang Yu served as the master of Ziqing Hall to monitor Li Zhengji, so is there a master of Hexi Hall to monitor himself?

Guo Song doesn't care about being watched, but he must grasp the movements of the monitors.

He immediately walked out of the inner house and said to a personal soldier: "Go find Wang Yue to come to the outer study to see me." ”

After a while, Wang Yue hurried over, knelt down on one knee and saluted, "See the envoy!" ”

Guo Song asked him to get up, and asked again: "Are there any people of unknown origin in the city, Han people, who know martial arts, and their accents may be from the Chang'an area." ”

Wang Yue shook his head, "In recent months, there have been many Han people who have returned, with a population of tens of thousands, but the humble post has not paid attention to the Han people, but to the Tibetans, Qiang people, or Sogdians. ”

Guo Song said slowly: "I mean, there is a secret agency under the imperial court, and it is very likely that they will send people to monitor me and report my situation to the imperial court at any time, I don't mean to eradicate them, but I want to know that they exist, and I want to know what they report to the imperial court, so find them, monitor them, don't alarm them, but buy the people in them." ”

Wang Yue suddenly said at this time, and hurriedly said: "I understand my humble position, and I will start the investigation today." ”

"Go ahead! Please keep me informed if you have any situation. ”

Wang Yue bowed and hurriedly left, Guo Song walked to the door, and asked a soldier outside the door, "What's the matter?" ”

"Envoy Qi, the historian just sent someone to send a roll of pigeon letters, which seems to be very important."

The soldiers presented a roll of pigeon letters to Guo Song, and Guo Song took the pigeon letter and slowly opened it, with only one sentence on it, "The Tibetan negotiator has arrived in Chang'an." ”

Guo Song suddenly breathed a long sigh of relief, there should have been a change of power within Tubo.

...........

As Guo Song judged, the Tibetan sub-prime minister Shang Zanjie who advocated recuperation replaced the great minister Shang Xijie and became the new Tibetan minister, he persuaded the Tibetan Zanpu to send an envoy to Chang'an to discuss the strike of the army and form an alliance, and the Tibetan envoy Luo led more than 300 people to Chang'an, and was warmly received by Cui Hanheng, the secretary of the Honglu Temple.

In the imperial study, Li Shizheng, the son of heaven, and the prime minister Yang Yan and the confidant Lu Qi discussed the arrangement of the alliance in Tubo, Lu Qi's two tigers fought for great success in Ziqing, Li Jing and Li Na brothers broke out a war for the right to inherit, they each led the army south of Qizhou to fight fiercely, so that Li Shilong Yan Dayue, rewarded Lu Qi with a hundred pairs of white jade, ten palace maids, and more favored him.

Of course, Lu Qi's ascension to the throne is also related to Yang Yan's strong recommendation, in order to get rid of Li Mi's constraints on himself, Yang Yan figured out Li Shi's intention to strengthen the monarch's power, pushed Lu Qi out, and took advantage of Li Mi's opportunity in Bashu to let Lu Qi gradually replace Li Mi's position as the left minister.

The two became the same party, cooperated tacitly, controlled financial and personnel rights, and gradually controlled the government.

Yang Yan bowed and said: "Your Majesty, this is a once-in-a-century opportunity, Tubo wants to recuperate, Hui Hui wants to return to the grassland, basically there is no time to harass the Tang Dynasty, we must ally with Tubo as soon as possible, and the two sides will strike troops to stop fighting, so that the border will be peaceful, so that we will have no worries, concentrate on cutting the domain, and take the Ziqing Jiedu Mansion and Weibo Jiedu Mansion in one go." ”

Lu Qi also said: "Yang Xiangguo is completely right, the alliance with Tubo is a top priority, we must be fast, Weichen believes that as long as the conditions of Tubo are not too excessive, we can all agree, we must solve the Western Front safely, in order to concentrate on dealing with the cutting of the domain." ”

Li Shi walked a few steps with his hand and said: "Tubo has put forward three conditions, the first is to open tea and horse markets in Longyou and Xichuan, which I can agree; second, to give up the Great Dou Tu Valley, this I feel that I need to discuss, and the threat to the west of the river is too great, and at most I can only give up half; The third is to let out Shazhou, this condition is difficult for me to accept, I also hope to meet the alliance as soon as possible, but the other party is too harsh, Yang Xiangguo, you go to negotiate with the Tibetan envoy again, replace the third article, and reduce the second article by half. ”

Lu Qi was about to persuade Li Shi again, but Yang Yan glared at him, Lu Qi had to swallow back the words that came to his mouth, Yang Yan knew Li Shi's mind too well, and the city was boiling when he recovered Shazhou, if they were lost in the negotiations, they would be scolded to death by the world.

"Wechen also thinks that the other party's third condition is too much, but the other party is just offering a price, and I have to fight back strongly, Wechen will definitely fight for it."

Li Shi nodded, "I'm looking forward to the good news from Xiangguo." ”

Li Shi picked up the report on the table again and asked, "Regarding Liang Chongyi's willingness to surrender to the imperial court, what do the two Aiqing think?" ”

Yang Yan said with a smile: "The minister thinks it is completely acceptable, summon Liang Chongyi to return to the dynasty, and give him a high-ranking idle position, even if the Shannan Dongdao is successful, Your Majesty can issue an order for Li Xilie to return to Huaixi and canonize him as the king of Huaixi County." ”

Li Shi said happily: "It is exactly what I want, I immediately issued an order to Li Xilie." ”

.......

The negotiations between the imperial court and Tubo are still continuing, the first round is the negotiation between Cui Hanheng of Honglu Temple and the special envoy of Tubo, the two sides put forward their own conditions, and the second round will enter substantive negotiations, and Yang Yan will personally negotiate with the envoy of the other party, Yang Yan rejected the other party's attempt to return to Shazhou.

After several arguments, the two sides first reached the first condition, opening a mutual market, and the Tang Dynasty also learned the lessons of the Hui Dynasty, insisting on private trade as the mainstay, and the official did not participate, which avoided the situation of buying each other's materials at high prices.

The second condition, the two sides finally agreed, the Tang Dynasty gave up half of the big Dou Tu Gu, this problem is not big, the Tang army occupied all the Da Dou Tu Gu, which also posed a huge threat to Tubo, and the two sides accounted for half of it, which was also a kind of balance.

The third condition, Tubo also knew that it was impossible to claim back Shazhou, so Tubo changed the condition to the Tang army's withdrawal from Shule, on the grounds that the Tubo herdsmen should be concentrated in the Shule area, and the Tang army's presence in Shule was a huge threat to the Tubo herdsmen.

Li Shi didn't say anything about this condition for a long time, he still clearly remembered what Guo Song said to him, once he withdrew from Shule, it would bring serious political consequences, and all countries in Anxi were in the same spirit, and withdrawing from any country would affect the legitimacy of the Tang army in Anxi.

Yang Yan saw Li Shi's hesitation, so he persuaded him: "Your Majesty, Weichen knows the importance of Shule, and he also knows very well that Tubo has cultivated and recuperated for a maximum of ten years, and we are also expedient, just to buy time for the reduction of the domain, and the Anxi channel has been opened, once the situation requires it, we can also recapture Shule at any time, we need to weigh the pros and cons now, which is more important, is Anxi important, or is it important to cut the domain, Weichen is still that sentence, the Central Plains is not quiet, why should we take it away?" His Majesty should focus on the Tang Dynasty. ”

Is Anthy important, or is it important to cut the feudal domain?' ’

This sentence focused on Li Shi's key point, Li Shi was silent for a long time, and finally nodded.
