Zhang Zheng was a little incredulous, how could such words come out of the mouth of Li Jing, a killing god. This is unscientific, unreasonable, and unreasonable.

If it weren't for his father shaking his head slightly, Zhang Zheng would have wanted to refute Li Jing: "Your existence is really hurtful to the heavens and the peace." But Zhang Gongjin knew Zhang Zheng's temperament, and hurriedly gave him a slightly calm look.

Only then did Zhang Zheng suppress the swear words that he almost wanted to blurt out in his heart. As soon as Li Jing's words came out, not to mention Zhang Zheng's disbelief, even Li Shimin, who was on the throne, cast a surprised look at Li Jing.

The generals were even more surprised in their hearts, you Li Jing said this, aren't you afraid of being struck by lightning? But it was only for a moment that the generals understood that Li Jing's words had a profound meaning.

There are four words that hurt the sky and sound, which sounds critical. But digging deeper, Li Jing, the old fox, is playing Tai Chi.

It seems that everything has been said, and it seems that nothing has been said, neither expressing a position to stay, nor saying that it will not stay.

Zhang Zheng didn't think of this stubble, but he was misled by Li Jing's words in a hurry, and thought he didn't agree.

"Your Majesty, the minister thinks this thing is good, it's a good thing. If you can equip the army on a large scale, you will see who dares to touch my Tang Dynasty's tiger whiskers. It's just that I don't know how much this thing costs, but there is the possibility of large-scale production, and I asked Zhang Xiannan to answer for the old man. Li Ji's eyes showed a gleam, and he didn't pick up Li Jing's words, but stood up and aimed the conversation at Zhang Zheng.

"I'm curious, this thing shouldn't be cheap." Li Shimin was noncommittal to Li Jing's words, and handed the small clay pot in his hand to the generals for circulation, and then continued Li Ji's words.

Zhang Zheng stood up, thinking to himself that this is right, how can there be a reason to put it away if it is too powerful.

If the Tang Dynasty is so open-minded, what is the difference between it and wild boar skin, and what qualifications does Li Er have to be praised as the first emperor of the ages by later generations.

"Your Majesty, the cost of this thing is about five cents."

"What, five cents, are you sure?" Li Ji exclaimed, a little incredulous, how could such a powerful weapon cost only five cents?

You must know that the Tang Army's conventional standard weapons, even the cost of an arrow is more than five cents.

"Zhang boy, are you serious?" Li Shimin glared at Zhang Zheng suspiciously. Zhang Zheng saw that everyone had an expression of disbelief, and said with a serious face: "Of course the minister is serious, this thing was made by the minister, can the minister still offer less?" Of course, Zhang Zheng did not offer less, but quoted more.

In terms of the purchasing power of copper coins in the Zhenguan period, five coins were enough to make two such small clay pots filled with gunpowder, plus the cost of manpower.

And the most expensive of them are nothing more than sulfur and small clay pots used to hold gunpowder. The other two ingredients, charcoal and pins, are everywhere in Datang, and they are simply given for nothing.

Of course, this is just the case of doing one or two as a cannon battle. If you want to make these things in large quantities, then you must find someone to buy them, and people need to pay for them to collect these things.

But even so, the cost of one will not exceed three cents. As for why he overreported, well, Zhang Zheng did it on purpose.

"Good! Good! Good! Such a sharp weapon, and the cost is so low, if my Datang whole army is equipped ......" Li Ji was so excited that he said three in a row.

He really wanted the Tang Dynasty army to be equipped with such a sharp weapon from the bottom of his heart. Needless to say, what nonsense the general is useless for, didn't anyone make this thing explode on its own?

As soon as Li Ji's words came out, Niu Jinda, Chai Shao and others also figured out the joints, and said, "Your Majesty, Weichen seconded it." ”

"Your Majesty, the minister also thinks that this thing is good, and the army should be equipped on a large scale." Zhang Gongjin spoke, his own children, of course, must be supported.

And at this time, no one cares whether this thing is left or not. Except for Li Jing, who kept silent, everyone else thought that their army could be equipped with this new weapon.

Li Shimin nodded: "I understand what you mean, but this thing is a big matter, whether to hand it over to the ordnance superintendent, or to re-establish a department, you still need to think about it." ”

"Of course, it is to re-establish a firearms bureau, dispatch craftsmen from all over the world, and immerse themselves in the research and development of firearms with greater power and more explosive power, Your Majesty will not think that this is the greatest power of firearms." Zhang Zheng, who listened for a long time, finally couldn't help but speak.

What is there to think about in this matter, from the perspective of confidentiality, from research and development, from funding, to independence, etc.

They should all set up a separate department and hand it over to the ordnance superintendent, do they know firearms?

"Firearms?"

"That's right, Wechen calls this new weapon a firearm." Since he had accosted him, Zhang Zheng simply let go of his words, and then bowed his hand to Li Shimin, and continued.

"Your Majesty, the firearm was discovered by Weichen, and the minister thinks he knows a lot about this firearm. According to Chen's research, the power of this firearm is more than that. The most important of these was gunpowder, the core of the explosion in the clay pot. If enough manpower can be mobilized and the gunpowder recipe can be improved after many experiments, it may be possible to create more powerful firearms. But this requires the financial cooperation of the court, as well as the strong support of the elders. Therefore, the minister's opinion was that this item could not be handed over to the ordnance superintendent. After listening to Zhang Zheng's general argument, everyone looked at him, and Li Shimin couldn't help but ask curiously: "Oh, in this way, you already have a manuscript in your heart?" And according to you, firearms are not enough to be so powerful now? Zhang Zheng nodded, since the words have been said about this, he must come up with something real, otherwise how to shock this group of turtles.

"However, Your Majesty should know that in the ancient wars, the tools used by our human race were nothing more than wooden sticks and stones. However, when the Three Emperors ruled the world, there was a mature metallurgical method, so bronze became the main war tool of the human race. Even in the Spring and Autumn Period and the Warring States and Pre-Qin periods, chariots, bows and arrows, swords, guns and halberds were popular. The times are developing, and in my Tang Dynasty, bronze weapons have gradually been replaced by weapons made of stronger steel due to their soft texture. And now, Weichen has developed a firearm with even more amazing power, and how lethality is compared to the sword is what His Majesty has seen with his own eyes. Now that firearms have just appeared, even Weichen does not dare to guarantee that the development of firearms will come to an end. Take a clay pot as an example, whether it can be replaced with an iron can, and if the iron pot is not good, whether it can add iron thorns to the gunpowder, or add steel balls. Everything is difficult at the beginning, but it is even more difficult for a traveler to persevere. This thing was handed over to the ordnance superintendent, and Datang could only get a small clay pot with an amazing sound. If a separate department is set up and studied by a special person, Datang may obtain ten or twenty new types of firearms. I hope Your Majesty will think twice. ”
