The time for a few people to talk soon came to the dinner, and Fang Xuanling naturally stayed in the palace, which was not uncommon for the prime minister of a country.

"I've heard that you've used a new thing on the grasslands, isn't it the gunpowder you mentioned earlier?"

After talking about serious things, the emperor began to inquire about gunpowder, originally Li Xiang was going to dedicate it to the emperor, but because of the Tuyuhun matter, this matter was delayed, not to mention that the emperor didn't take it to heart at that time, thinking that this thing was not so powerful, it was purely Li Xiang's exaggeration.

What is his grandfather's mind, Li Xiang also has an idea in his heart, gunpowder is a monopoly in this era, although Li Xiang is willing to make Datang live a little better, but the current Datang is not Li Xiang's, so gunpowder must be grasped in his own hands.

"It's indeed the gunpowder that my grandson used to say."

According to Li Shimin's thoughts, Li Xiang, this kid must be more cunning, even if he takes the initiative to ask, this kid will never admit it, but he didn't expect to admit it like this, but Li Shimin didn't know how to say it.

"Weichen has also heard that this kind of gunpowder is very powerful, which is also a reason for His Highness's victory on the grassland, if all my Datang armies are equipped with this gunpowder, then in the future, the national strength of my Datang will at least more than double, if the surrounding countries see such powerful weapons, will they dare to have a dispute with my Datang?"

Of course, Fang Xuanling knew what Li Shimin was thinking, so he immediately turned into this matter.

"Fang Xiang is right, but gunpowder is expensive, not inferior to gold, if all the armies of the Tang Dynasty want to be equipped, the cost is not a little bit."

Li Xiang said a word, and immediately extinguished the heat of these two people.

If the value of gunpowder is equivalent to gold, it is indeed impossible to equip it on a large scale, and the value of gunpowder has also guessed, it must be very expensive, but it is definitely not equivalent to the value of gold, but now they have no secret recipe, all of them are in the hands of Li Xiang, and naturally Li Xiang is what he says.

However, according to the reports of the spies on the front line, gunpowder is indeed very precious, officers at all levels are strict with their subordinates, usually all gunpowder is weighed, any loss of gunpowder must be explained in writing, if the explanation is not clear, no matter what kind of origin you have, you must accept strict punishment.

"Don't believe it, grandfather, what the grandson said is the truth, this is the material of gunpowder......"

Li Xiang immediately took out a piece of paper from his pocket, which was recorded as the material of gunpowder, of course, the material on it was half-true, and some of it was added by Li Xiang himself.

Li Shimin hurriedly asked Wang De to take it, such as the treasure in his hand, although Li Shimin has not heard of some materials, but among the several materials he knows, it is indeed very expensive, if it is configured according to this formula, although it is not equivalent to gold, but it is not far behind.

"There are several materials that are extremely rare, even if we bother to buy them, it is impossible to buy too much, so in the matter of Tuyuhun, Sun Er is in favor of negotiating with them, if there is enough gunpowder, Sun Er will definitely immediately lead the troops south and set foot on Tuyu Hun."

What Li Xiang said is also a half-truth, in fact, he has enough gunpowder, but at that time, when the major families seized Li Xiang's fruit in Tuyuhun, Li Xiang was already arranging this matter, since you want to swallow this apple, then I have to make this place into a poisonous apple.

"You can collect this thing first, the court craftsmen probably can't make it, but you must not leak it out, since it is so rare, then it will stay in your army for the time being, as for the consumption and report directly to the household department, but on the city wall around the palace, can you place some?"

Li Shimin thought of the Xuanwumen Revolution back then, if someone wanted to launch a coup d'état again, although Li Shimin was now fully sure of suppression, but if there was such a strong thing, wouldn't it be a little more certain?

"Shooting condescendingly on the city wall, this is indeed a very good way, the grandson immediately arranged for someone to buy it in the dangerous place of the city wall, but the grandfather has to find a proper person to guard, especially gunpowder, if you don't weigh it every day, once it falls into the hands of people with bad intentions, the safety of the palace ......"

Gunpowder is a double-edged sword, Li Xiang put all the gunpowder in the hands of the system soldiers, so there is no need to worry about the gunpowder will flow out, or even one or two will not flow out, but in the hands of Li Shimin's people in the palace, I am afraid it is difficult to say.

"Then you prepare for the time being, and I'll arrange the rest."

Although Li Shimin has not really seen the power of gunpowder, he has already received a part of it, and he can naturally speculate that it is natural to be careful and careful when placing such a thing in the palace, and no one who is not his cronies can use it.

Fang Xuanling was a little disappointed beside him, although he knew that Li Xiang might be making trouble, but anyone would probably do it, after all, this is not a gadget, if it can be convenient for the entire Tang Dynasty, then the border guards can be reduced by more than half, and the expenses of the imperial court can be reduced accordingly.

Now that the Li Xiangyuan is also placed in the Imperial City, this can be regarded as giving them a chance, if the craftsman can develop it, the cost may be lower.

Of course, Li Xiang also knew what they thought, so what he took out were some rudimentary black powder, this kind of thing has limited power, even if you can develop it, it will be ten or twenty years later, and we will have already replaced it with smokeless gunpowder in the middle, naturally we are not afraid that you will master this technology, we will definitely lead the world in terms of science and technology, and we must all be in our own hands.

Although the meal did not meet their respective requirements, it was also very perfect, and Li Xiang was given thirty days of vacation, including his soldiers, and thirty days later he went to the Beiya Forbidden Army to take up his post.

"Your Highness."

Li Xiang and Fang Xuanling left the Qinzheng Hall together, Fang Xuanling basically didn't take the initiative to speak, but after walking down the hall, Fang Xuanling still took the initiative to stop Li Xiang.

"Can you give me some advice?"

In the face of Li Xiang, the think tank of the Tang Dynasty, he bowed down very modestly to ask for advice, this person influenced almost all the policies during the Zhenguan period, but he was not an ordinary person......
