In addition, Li Jiancheng constantly emphasized that the ultimate purpose of sending students to learn gunpowder technology was to protect the people of the Great Sui in the territory from the threat of foreign enemies, and to suppress the excuse that Li Wenyuan might have to refuse. Although Li Jiancheng has learned Li Wenyuan's final attitude through Wu Niang, after all, it is only Wu Niang's words, if Li Wenyuan changes his mind during the time when Wu Niang leaves Li Wenyuan, then won't the purpose of his trip fail? So in his words, Li Jiancheng still tried his best to cut off the possibility of Li Wenyuan's refusal.

Li Wenyuan looked at Li Jiancheng in front of him, his face was as calm as an ancient well, until his scalp was a little numb when he stared at Li Jiancheng, and then he said slowly: "Gunpowder technology is our secret technology of the Great Sui, and it stands to reason that no matter who comes, we will not agree to teach it to them." However, since the noble envoy has the idea of protecting the territory and the people, and not using it for foreign aggression and expansion. Then it is okay to teach the international students mentioned by the envoy, but the clothing, food, housing and transportation of these international students will be provided according to our students in the Western Regions, but because these international students are some people who have no foundation, if you want to teach them this skill, you have to start from the most basic learning, so if you want to get a musket to protect the territory and the people in a hurry, then don't think about what will happen after these international students return from their studies. In addition, the expenses for this period, including the remuneration of the teachers who teach the most basic courses for these international students, will probably have to be provided by the forces behind the envoys. After all, my life is not easy now, and after the territory is bigger, there are places where money is used everywhere, and I am afraid that I will not be able to afford the related expenses of these international students. These should also be explained to the envoy in advance, so as not to end up with a happy end in this cooperation, and it will not be good to have a misunderstanding at that time. ”

Li Jiancheng did not mean to refuse when he heard Li Wenyuan's words, but further discussed many matters such as other related expenses for international students, and knew that this matter was appropriate. So he nodded hurriedly and said: "This is naturally borne by us, you don't have to worry about this, His Royal Highness Tang Wang only needs to make a list of all the expenses of these international students, and send them to Chang'an City through the envoys, and then their funds will naturally be packed from Chang'an City and sent to Dunhuang County immediately." ”

"Pay with one hand, deliver with the other. Our people are only responsible for sending the list of expenses to Chang'an City, and we don't even ask how the funds are transported from Chang'an City to Dunhuang County in the Western Regions. As long as the funds are sent to Dunhuang County, all kinds of matters have to be troubled and expensive during the period. After Li Wenyuan listened to Li Jiancheng's words, he nodded, and then said to Li Jiancheng.

After listening to Li Wenyuan's words, Li Jiancheng couldn't help nodding, and he agreed with Li Wenyuan's statement, but Li Jiancheng had already scolded Li Wenyuan's ancestors for eighteen generations in his heart: This Li Wenyuan obviously knew that his relationship with Xue Ju was hostile, but he still had to find a way to transport the funds to Dunhuang County by himself, and difficulties and dangers during this period were naturally indispensable. In this regard, he can only make a decision after discussing with his father, but since his father said that he would complete this matter no matter what, Li Jiancheng can only pinch his nose to accept Li Wenyuan's request first, and then think of other ways.

The general framework has been negotiated, and the next details will naturally have the corresponding ministers to negotiate with Li Jiancheng in detail, and there is no need for Li Wenyuan to come out in person here. Therefore, Li Wenyuan was the first to leave the court and prepare to return to his mansion, after all, there are still countless official affairs waiting for him to deal with in his mansion. But on the way back, Li Wenyuan met Empress Xiao who came out of the garden. So after the courtesy of the monarch and the minister, Empress Xiao took the lead in asking Li Wenyuan: "What? I heard that Li Jiancheng came to the Western Regions? ”

When Li Wenyuan heard this, his brain buzzed. Somehow, the Empress Xiao in front of him has always been very unkind to see Li Yuan, and has suggested to Yang Guang many times that he has the idea of depriving Li Yuan of his hereditary title, but it has never been adopted by Yang Guang, as for why he has been so obsessed with stumbling against Li Yuan, no one knows. This time, when he heard Empress Xiao mention Li Jiancheng's visit again, Li Wenyuan said in his heart that it was not good, if Empress Xiao really wanted to stir up this matter, then some things that were easy in the original plan might have to take a little more twists and turns.

Thinking of this, Li Wenyuan shouted angrily to the subordinates who came with Empress Xiao next to him: "Who didn't have a long eye to tell the Queen Mother about this?" She wants to do her best to educate Your Majesty every day, hoping that Your Majesty can take on the important task of governing the country as soon as possible. ”

After listening to Li Wenyuan's words, Empress Xiao hurriedly waved his hand to stop Li Wenyuan's scolding, and then said to him: "None of them blame me, it was when I passed by your court when I heard your words discussing in the court, and then I knew that Li Jiancheng was here." Don't you think that you can take this opportunity to scold a few subordinates to take over this matter in one fell swoop, and tell me what Li Jiancheng is doing? ”

Li Wenyuan saw that the method that had always worked was out of order at this moment, so he could only answer truthfully: "Li Jiancheng should have been instructed by his father Li Yuan to send some students in the Western Regions to learn our gunpowder technology. ”

"I heard the conversation between you and Li Jiancheng outside the hall before, and what you mean in your words is that you have agreed to Li Jiancheng's request and are determined to accept the students he sent out and teach them how to make gunpowder, right?" After listening to Li Wenyuan's words, Empress Xiao continued. Later, he saw that Li Wenyuan had no intention of refutating, so he said with some anger: "As a woman, I still know that gunpowder is a secret among our secrets, and it is also a magic weapon for us to defeat the enemy. How can it be so easily taught to outsiders who may become enemies in the future? What's more, what Li Jiancheng said above the court was too much, as an envoy sent by Li Yuan, how could he make up those nonsense things in the court? Is he not afraid of bearing this reputation for slandering others? ”
