Li Xinchen smiled and waved his hand, of course he knew that Yang Su couldn't be fake, because even if it was something else, Yang Su's eyes and the temperament beyond ordinary people couldn't be imitated by ordinary people.

Moreover, the current Yang Su has not gone through the battle to destroy Chen, and he is not a really important person in the Northern Zhou Dynasty, so even if he is pretending, he will not pretend to be him.

Li Xinchen's eyes fell on Yang Su's body, and he said with a smile: "This person also knows, I didn't expect that your country would send Brother Dao to come." ”

In addition to expressing his surprise and surprise, Li Xinchen naturally ridiculed Yang Su's talent. Of course, Yang Su couldn't not understand the meaning of this pun, and immediately bowed slightly: "Yu has always been talented and virtuous, and the imperial court sent Yu to solve the task of solving some minor problems with General Li." ”

At this time, Li Xinchen was holding a teacup, and his hand stopped in the air, he didn't expect Yang Su to come back so directly, this guy is really an out-and-out straight man like in history. Maybe this is why he rises and falls again and again because he can't control his mouth, or maybe it's one of the reasons why he was kicked to Li Xinchen to take charge of such a thankless task.

After all, it is not a glorious thing to come to Li Xinchen to contact here, what is done is only the secret decree of the Northern Zhou Emperor, and even the official uniform cannot be worn, and once there is a deviation when transmitting the message and conveying the meaning, the fragile balance between Li Xinchen and the Northern Zhou Dynasty is completely broken, then this responsibility must be borne.

Therefore, Li Xinchen felt that the Northern Zhou Dynasty court let Yang Su, a guy with a poisonous tongue, come to him, which was somewhat exclusionary.

After Yang Su finished speaking, he smiled and looked at Li Xinchen, in fact, what he said just now was also a bit deliberate, he also wanted to test Li Xinchen's depth, if Li Xinchen was angry because of this, then Yang Su would feel a lot easier, because his new friend and new opponent were not as big as he imagined, and he was easy to deal with if he had weaknesses.

And Li Xinchen obviously didn't let Yang Su get his wish, he just bowed his head slightly, and said in a deep voice: "Brother Daoist is true, Brother Daoist should be a careful person, and it doesn't hurt to let Brother Daoist do the supervision and implementation of some small things." ”

Yang Su was slowly tasting tea at this time, and when he heard this sentence, he almost squirted out the tea in his mouth. I don't know if Li Xinchen understood what he meant, but Yang Su knew very well that Li Xinchen was clearly mocking him, and he was even worse.

And Li Xinchen didn't seem to give Yang Su a chance to breathe and fight back this time, and then said: "According to the previous agreement, our army will defend Jiameng Pass and Sword Pavilion and other places, but if we don't strengthen the defense of Jiameng Pass, this should have been seen on the road where Brother Dao came." And it stands to reason that your army should retreat to Hanzhong and go to Fangling instead, but why is Li Xunbu still at the entrance of Shu Road now? ”

These oral agreements between Wei Xiaokuan and Li Xinchen are called "oral", in fact, they are all on another secret agreement, which is the biggest secret between the two parties, and only Xiao Shilian and Pei Zilie know on Li Xinchen's side, and on the Northern Zhou side, it should only be limited to the high-level Northern Zhou officials above Wei Xiaokuan and Wei Chi Yuan, and of course Yang Su, the envoy.

According to these "verbal" agreements, Li Xinchen could only repair and strengthen the defense of the Sword Pavilion, while the entrance fortresses of Langzhong, such as Jiamengguan and Zitong, could only be guarded by troops, but could not continue to repair and reinforce, thus weakening their role as Xiongguan.

In exchange, the Northern Zhou army was supposed to retreat to Hanzhong and Xinzheng, and gradually move to Xiangyang. But now Wei Chi's troops have arrived north of Fancheng, and Wei Xiaokuan has also moved his Chinese army to Fangling in the upper reaches of the river, but Wei Xiaokuan's general Li Xun still led seven or eight thousand soldiers and horses to garrison at the entrance of Shu Road.

This is certainly not the way it was promised.

Yang Su obviously expected that Li Xinchen would have this problem, and his address to Li Xinchen became serious: "General Li doesn't need to worry, since the agreement is so, then our Great Zhou will not violate the agreement, but when Li Xun's department retreated, there was a lot of grain, grass and baggage that needed to be transferred, so it would take a certain amount of time to evacuate and return." ”

Li Xinchen sneered, of course he didn't believe such a clumsy excuse. And Li Xinchen also knew that even if Li Xun slowly and leisurely led his troops to retreat to Hanzhong, he would definitely leave a certain number of troops at the entrance of Shu Road, otherwise Li Xinchen would directly lead the army to rush out of Shu Road, and there were really not many barriers in Hanzhong.

The weaknesses of places such as Chushui and Dingjun Mountain are too obvious.

Of course, correspondingly, Li Xinchen will not abide by the agreement, the reason why he brings up this matter now is because Li Xinchen has not enough manpower and material resources to mobilize to repair some dilapidated Zitong and Jiamengguan and other places, so now take this opportunity to force the Northern Zhou first, if Li Xun can retreat quickly, it is good, even if Li Xun really depends on Li Xinchen or not, he doesn't care.

After all, once he starts to repair these fortresses and barriers on the north side, the soldiers and horses of the Northern Zhou Dynasty will also be moved, and there is not much difference from the current situation.

The so-called contract was originally meant to give everyone a chance to breathe, and then take it out and tear it up, Li Xinchen is very clear about this truth.

And Yang Su obviously knew what Li Xinchen wanted to express, which was expected by Wei Xiaokuan and others, so Yang Su didn't feel strange, and said on this topic: "The imperial court has agreed to the matter of exchanging merchants before, but it is limited to Hanzhong, and the caravan is only Yangping Pass and Fangling. ”

Li Xinchen then responded: "We have also selected Zitong and Langzhong, and the caravan is no more than the Sword Pavilion and the Heavenly Palace Courtyard. ”

Yang Su nodded, and the scope delineated by Li Xinchen was also expected.

Everyone knows that the main purpose of the exchange of merchants between the two sides is of course not to facilitate exchanges and communication between the two places, but to be able to send spies and spies more easily, so it is necessary to exchange businessmen, but it is impossible to open up the whole territory, and it is enough to demarcate a range.

Something is better than nothing, and you can't get an inch.

Withdrawing troops and communicating with merchants are two important contents of the secret agreement, and now whether the two sides want to fulfill it or not, at least the face project has been completed, which also makes Yang Su breathe a sigh of relief. He had to admit that Li Xinchen was indeed a difficult character to deal with, and this young man showed a very strong desire to attack, which made Yang Su more vigilant.

Of course, for Yang Su, this time he came not only for the implementation of the secret agreement between Beizhou and Li Xinchen.

He had other things to discuss with Li Xinchen, not as a courtier of the Northern Zhou Dynasty, but as the head of the Hongnong Yang family.

This is one of the reasons why Yang Su did not have the slightest objection to the arrangement of the imperial court.
