After Li Er received the news that Dafeichuan besieged the 60,000 troops of Tuyuhun, Fu Yun hanged himself, and his son Fu Shun led his troops to surrender, the excitement did not last for three days, and another report sent back from Tubo instantly knocked his good mood into the dust - Tubo gathered a large army in the area of Jishi Mountain, and his intentions were unknown!

Located at the source of the Yellow River, Jishi Mountain used to be the dividing line between Tubo and Tuyuhun, and later the two countries were defeated by a war over pasture. Since then, Jishi Mountain has become the territory of Tubo, and Tuyuhun has also been driven all the way north by it, entering the territory of Datang, and an invasion of Liangzhou has occurred.

And now, Tubo is stationing troops in Jishi Mountain, and what his intentions are are really difficult to figure out.

Because of its extremely special geographical location, it occupies the geographical advantage, whether it is to the west or to the north, there are very convenient conditions, if you rush down the mountain, it will not take a few days to enter the territory of the Tang Dynasty and launch an attack on the border states of the Tang Dynasty.

Thinking about these things, Li Er once again thought of Li Chengqian, and thought of the bastard boy who was neither in tune nor reliable, but also remembered what to eat and not to beat.

When he first moved into the Taiji Palace, Li Chengqian said that Tubo would be a problem for the Tang Dynasty in the future, and now it seems that the original prophecy has been confirmed little by little.

It took only three years to quell the aristocratic rebellion in Tubo, and after quelling the rebellion, there was still the strength to take most of the territory of Tuyuhun in one fell swoop, and there was no way to chase the lord of Tuyuhun to the sky, and there was no way to enter the ground, so he could only run into the Tang Dynasty to try to cross the state to find a glimmer of life.

It's only been three years, and a doll who was only thirteen years old at the time has grown to such an extent in three years. I have to say that Li Chengqian, a bastard boy, seems to have chosen a good opponent for himself.

"Come, make a copy of this request and send it to the prince." Thinking of Li Chengqian's bold words in the Taiji Hall at the beginning, the corners of Li Er's mouth twitched slightly, intending to see what Li Chengqian would do if he knew about this matter.

After three years, the Tang Dynasty's flying pigeon biography has been fully rolled out, and if the information is not a particularly cumbersome official document between the various state capitals, it will generally be communicated in the way of flying pigeon biography, and even in the people, there are some businessmen who are very interested in this way of delivering letters quickly, and plan to invest in an information company.

Li Chengqian didn't care what these businessmen wanted to do, nor did he care whether the information companies invested by these businessmen would make a profit, and at this time he was taking the information transmitted from Chang'an and looking at it carefully, and he was in no mood to care about those messy things at all.

"Childe, what is this? It's all numbers, what the hell is written? Tianzuo and Tianyou stood behind Li Chengqian, craned their necks and looked at the note in his hand, trying to discover some major secret.

"Do you know Tibet?" Li Chengqian put down the note in his hand, turned his head to look at Tianzuo who was standing on the left, and asked.

With the ability to never forget, some people don't need a code book at all, all the passwords out of someone to remember a copy, the Tao is to save a translation!

"Tibet?" Tianzuo frowned, glanced at Tianyou, thought for a while and said, "Is it the place where you don't take a bath and feed the eagles when you die?" ”

"Well, it's pretty much the same, but it's not that they don't always take a bath, they also wash a few times a year, such as when they are born, when they get married, and when they die." Li Chengqian corrected Tianzuo for a moment, and then said thoughtfully: "Tubo is going to do something to my Tang Dynasty, if nothing else, it will be in this and next year." ”

"They're crazy, aren't they? A group of dirty natives also want to attack the Tang Dynasty? This time, Tianzuo and Tianyou were talking together, and it sounded quite three-dimensional.

"The human heart is insufficient!" Li Chengqian took a deep breath, looked at the note on the table, and said to Yang Yuxin, who was in a daze on the side: "Take a piece of letterhead, and by the way, take another dipping pen." ”

The manufacture of dipping pens is very simple, Li Chengqian used to make a lot of supervisors when he was fine, and later it was discovered that this thing can improve the writing speed after being proficient, and it slowly began to become popular in Datang.

A moment later, Li Chengqian wrote the letterhead that Yang Yuxin brought full of numbers that Tianzuo and Tianyou couldn't figure out, and then handed it to the little girl: "Let the arrangement be sent to Chang'an immediately." ”

"Whoa!" The little girl agreed, took the note and walked out of the room to find someone to deliver the message, while the twin brother asked curiously, "Childe, what did you write just now?" Isn't it some code? ”

"Those are the special code words of the intelligence department, you are not familiar with it when you just join, and when you return to Chang'an in the future, you will have the opportunity to come into contact with it." Li Chengqian patiently explained, and at the same time told the twins what he had just written.

As a result, as soon as Li Chengqian spoke, the question of the twin brothers came again: "Childe, how do you know that the Tubo people will definitely attack Songzhou?" Is there any basis for this? ”

Basis? Li Chengqian was stunned for a moment, his basis was the records of later generations, Tubo failed to ask for marriage, and sent 50,000 troops to fight with Niu Jinda in Songzhou City, and was later defeated by Niu Jinda.

However, there is no way to say such a basis, and no one will believe it, so Li Chengqian can only vaguely analyze the position of the Tubo army and the position of Songzhou in the Tang Dynasty.

After Tianzuo and Tianyou were defeated and exited the room, Li Chengqian let out a long breath, sighed and picked up the note from Li Er on the table again.

History records that Tubo only broke out its full strength after the ninth year of Zhenguan, and defeated Yangtong, Dangxiang, Bailanqiang, Tuyuhun, and the Songzhou battle against the Tang Dynasty launched in the twelfth year of Zhenguan.

But now it's only been six years of Zhenguan, and Tubo already has such a strong strength, is it really so powerful for his 'Colombian butterfly'? Just buying some hair from the Tubo people can make the Tubo strong so quickly?

If that's the case, I wonder what will happen if Datang sells some scalpers? Will it become stronger in a short period of time?

This time the contemplation lasted about two hours, and it was not until Yang Yuxin reminded him that it was time for dinner that Li Chengqian was awakened from his contemplation.

"Childe, there may be an unexpected surprise in a while, don't be too surprised." On the way to the dining room of the post house, Yang Yuxin had a mysterious smile on her face and whispered to Li Chengqian.

Li Chengqian said abruptly, and teased indifferently: "Don't worry, your young master has passed through many winds and waves, and it is by no means a little surprise that can scare me." ”
