The three envoys took the box, carefully wiped the dust on it, and opened it nervously, as if it contained some treasure more important than their lives.

The box opened, and inside was a stack of paper with clear patterns drawn on it, which could be seen on a closer look.

This box contains the blueprints of the Shenwu cannon!

This is the treasure that Tubo has dreamed of!

When the Tubo State was founded, when it was about to sweep the Eight Wildernesses, it was this Shenwu cannon that blocked the expansion of Tubo's territory.

If Tibet also had Shenwu cannons, there would be no gap between the two countries.

Some of the Tang Dynasty also have Tubo, and some of the Tubo ones are not necessarily available in Datang.

In recent years, Datang has entered a period of peace, relying on Shenwu cannons, foreign enemies dare not attack, so a large number of disarmament and saving expenses. Moreover, the army is also negligent in training, and the army's combat strength is much worse than before.

Moreover, the Tubo soldiers are already better at fighting, and in recent years, for the sake of the Shenwu artillery of the local Tang Dynasty, the army training has not been relaxed for a moment.

As long as the technology of the Shenwu cannon mastered by Tubo, the next eastward advance will inevitably be like a broken bamboo and go straight to Chang'an.

This is the important task of the envoys of the Tubo Kingdom, I didn't expect to make a deal with Princess Danyang and complete it so quickly.

After not believing their eyes for several hours, they looked at each other for a long time, and then asked, "Your Royal Highness, there is still cannonball making." ”

"It's all in the box, just rummage through it."

A few people looked through it for a while, and finally found the blueprint for making the shell hidden at the end.

The three envoys were so excited that their hands were shaking, and they kowtowed to Princess Danyang again and again in thanks.

Princess Danyang didn't care, as if it was just a beautiful woman who was sent out, and said casually: "Take it back to study it yourself, if I deceive you, the cooperation between us can be terminated at any time." ”

"Thank you, Your Royal Highness, thank you, Your Royal Highness, if there is nothing else, Your Majesty will leave first."

Princess Danyang nodded and beckoned them to leave.

The three envoys didn't dare to stay, they had the treasure in their hands, and if they got it, it would be miserable if they couldn't send it back.

Watching the three envoys leave, Hou Junji was a little worried: "Your Royal Highness Princess, the Shenwu cannon is the foundation of my Tang Dynasty, and now it is handed over to foreign people, will there be trouble in the future?" ”

"What this palace wants is to have an accident!" Princess Danyang said with a smile, "A pool of stagnant water in the Tang Dynasty has been too long, and an external force is needed to break the balance. Wasn't this Shenwu cannon made by Bai Song? Since he can make a Shenwu cannon, he must know how to deal with it. Even if the army of the Tubo Kingdom really used the artifact cannon, it would only be a temporary danger to the Tang Dynasty, and Bai Song would be able to beat them back one day. As long as Bai Song leaves Beijing, there will be more variables in Chang'an, and perhaps when Bai Song returns to Chang'an, this world will be a new world. ”

……

A carriage came from the palace of Beiding, and a man and a woman got off the carriage.

The men were thirteen or fourteen years old, and the women were only sixteen or seventeen.

The subordinates of the royal palace went up to communicate, and after confirming the identities of the two, the subordinates hurried to the outside of Bai Song's house to report.

"Li Zhi, the king of Jin, and Princess Chengyang are out asking to see each other."

Inside the house, Bai Song was training the lord of Mingzhu how to be obedient and sensible, and the little girl crackled and cried bitterly, and when he was in high spirits, he heard the unexpected visitor, and Bai Song was also very surprised.

"Husband, let these two wait, and we'll see you later."

It's the prince and the princess outside, let them wait outside?

Bai Song has this confidence, but it is a little strange that these two suddenly came.

The key is Li Zhi, this is the orthodox heir.

Li Chengqian is now annoying Bai Song, and he originally wanted to help him change history, but he actually robbed his sister.

Now how Li Chengqian will go in the future, Bai Song will not intervene again.

But he can't help but think about the future of the Bai family, and he still wants Li Zhi to inherit the unification in the future, and his relationship with Li Zhi can't be bad.

Thinking of this, Bai Song also dressed up and arrived at the gate of the palace.

The prince and princess who were high up elsewhere, standing in front of the Beiding Palace, were obedient children, saying that they would wait, there was no impatient emotion and action at all, and when they saw Bai Song coming out, the two stepped forward and bowed: "I've seen Mr." ”

The two of them are called Mr. Bai Song, that's right.

As early as when Li Chengqian was teaching in the East Palace, there were other younger royal children who were listening.

Li Zhi and Princess Chengyang are two of those young royal children.

Although I don't come to the class every day, I am definitely a student of Bai Song.

It's just that Li Zhi and Princess Chengyang in my memory are both children, and they have grown up in a blink of an eye.

Especially Princess Chengyang, she looks so slim and elegant, and the rules are very decent, and Bai Song didn't recognize it.

"Why did you come to the Beiding Mansion today?"

"The student has some questions and wants to ask Mr. Li Zhi is very well-behaved, with a waxy voice, and at first glance he is the type of student that the teacher likes.

Bai Song looked left and right, and found that the two of them were not brought by anyone, and the key was not the palace clothes they were wearing, but the civilian clothes, as if they had come over secretly.

Bai Song didn't ask questions immediately, and motioned for the two of them to come in with him.

In Bai Song's eyes, these two were still children, so he took them directly to the garden pavilion in the inner courtyard and sat down.

In the past two days, the county lord of Mingzhu has behaved very well, and he actually prepared tea in the small pavilion first, and took care of the affairs of his subordinates by himself.

But she also had a purpose, that is, to dismiss all the maids, to stay outside the pavilion by herself, and if she had anything to serve, she went.

You can hear something from the outside, and you can learn something.

Bai Song gradually understood the county lord of Mingzhu, and knew that her careful thinking originally wanted people to take it away, but he felt that he was not so vigilant, and the family didn't even have a trust, and it was awkward.

I just let it go.

What can two children say when they ask questions?

Bai Song took the two of them to sit down under the pavilion, drank a few sips of tea first, and then asked: "King Jin said that he wanted to ask questions, but I don't know what questions he wanted to ask?" ”

Li Zhi is too young, and he is still a little dazed, but he can see that there is worry in his eyes, and there seems to be something unspeakable.

On the other hand, Princess Chengyang suddenly got up and knelt down: "Sir, my brother is in a critical situation, please ask Mr. to protect him." ”

"Huh?" Bai Song was stunned for a moment, and first helped Princess Chengyang up, "Why do you say this?" Don't be in a hurry, get up and speak slowly. ”

"We got the news that we heard that the prince made a big fuss in the East Palace and injured his legs and feet, and I am afraid that it will be difficult to hike in the future. When the fourth brother heard the news, he had moved his heart to win the prince, the eldest brother and the fourth brother competed, and the younger brother was young and had no one to rely on, but he was afraid that one day he would become a victim between them. ”
