Together with Meng He, the three of them went out of Xianyang Palace, and went straight to the Rewu Fang in Shanglin Yuan, and at the same time asked Meng He to send someone to call Gong Gong together.

Along the way, I saw a lot of people who were surveying the new city, and the original plan was to plan out the drawings of the new city this spring, but it involved two palaces and two temples, and the Daqin business and trade I asked for were too large, so I couldn't draw the new city plan for a long time. Simply told Bai Chong, don't worry, take your time, building a city is not an overnight thing, it is better to plan carefully.

When he arrived at Rewufang, the new Rewu Commander Zhou Qi was busy making nitrate.

"How much saltpeter has been made now?" I looked at the nitrate field in front of me, and there were several large cauldrons piled up next to it, and there was a drying area.

Zhou Qi bowed and said: "Back to Your Majesty, there is only one vat of saltpeter available, and the rest is still being boiled." ”

A few people went into the house to take a look at the saltpeter that had been made, and there were clay jars about half a person high, all of which were sealed with mud to prevent moisture.

"You don't have to open it to see it, you've tried the purity, right?" Just looking at their crystallization method, there should be no problem, but it is inefficient, and it takes several times of cooking to obtain crystals that reach the specified concentration of potassium nitrate.

Zhou Qi replied: "Back to Your Majesty, there is no problem, it is completely able to meet the requirements of making gunpowder." ”

I nodded: "How much stone flow yellow and charcoal powder are there?" ”

"Shiliuhuang is not available yet, charcoal powder has been made enough, this is easier to obtain."

As he was talking, Gong Jin walked in from outside: "I've seen Your Majesty!" ”

I waved my hand, frowning slightly: "Zhang Han, do you know Shi Liuhuang's progress?" It's been half a year, and there is nothing at all? ”

Zhang Han arched his hand and said: "Your Majesty, Shiliuhuang can only be found in places with natural hot springs, and the right prime minister according to the location told us by His Majesty, combined with the national chronicles, found that it is mainly concentrated in the Lingnan area." Now we have found many places where you can collect stone flow yellow, one is difficult to mine, and the other is difficult to transport from Lingnan, so it is a little slow. ”

I sighed lightly and looked at Gong Zhi: "How is the flintlock pistol made?" ”

"Back to Your Majesty, because the parts need to be polished a little bit, so the flintlock pistol that has not yet been formed has been made......" Seeing that my brows were furrowed more and more tightly, Gong Jinjin hurriedly added: "However, the lathe drawings given by His Majesty to the minister, the minister has organized people to study them carefully, as long as the lathe is made, the process of grinding the parts will be much easier, and the progress will definitely be accelerated." ”

I glanced at the two of them and said unhappily: "I know that it is difficult to create these things, but Shi Liuhuang has been half a year now, and he has not collected any of them; Not to mention the flintlock pistol, I gave you the drawings in the second year of the establishment of the Jiangzuofu, and it has been three years now, right? Not even a single sample was made. Is the mind not on it? Or is it really difficult? ”

The two hurriedly bowed down and said, "The minister is guilty!" ”

I glanced at Meng He: "Go and call Li Si to me." ”

Then take the two to watch the process of making nitrate.

Half an hour later, Li Si hurried over.

I looked at Li Si and went straight to the point: "Although I handed over the matter of making gunpowder to Zhang Han, Shiliu Huang Zhen handed it over to you to find, right?" Why is the progress so slow? ”

Li Si said embarrassedly: "Your Majesty, this, there have been recent wars in the North Huhu City, the Western Regions, and the border passes...... There are a lot of things, the minister, the minister is slightly negligent, please Your Majesty to surrender! ”

"The reason why I established Rewufang is because I don't want to rely on business, allies, and numbers to make those barbarians submit. You still don't really realize the power of thermal weapons bombs, guns, cannons, and the power of bomb explosions, but I tell you, compared to guns and cannons, bombs are just powerful, and the bombs you make are unstable, so you can't let soldiers carry bombs that may explode at any time to fight the enemy, right? ”

I continued: "But guns and cannons are different, Daqin has guns, and when you fight against the barbarians, it's like you fighting against a person with an iron sword empty-handed, and the gap is so big. ”

I was just about to continue to tell them about the power of the hot weapon, when a soldier suddenly came outside: "Your Majesty, three truckloads of goods have come to Shanglin Yuan, saying that they are goods sent by Ba Shi Taoyao, and there is a handwritten letter issued by Your Majesty." ”

"Oh?" My eyes lit up: "Let the leader come in." ”

Not long after, a tall man walked in, and at first glance it was from Bashu, because of the straw sandals on his feet, which were hot and humid, and he was used to wearing straw sandals.

Speaking in a Bashu dialect: "Zunjia, the master let us find the stone flow yellow and saltpeter, saying that he took the handbook and sent it directly to a place called Shanglin Yuan, dare to ask but here?" ”

I was overjoyed: "Yes, here it is." Zhou Qi, quickly send someone to pull the goods in. ”

While asking, "How much stone flow yellow and saltpeter are there?" ”

The man said: "There are more saltpeters, and there are two carts." Shi Liuhuang only has one car, and the head of the family told me that this thing is not easy to find, and I don't know if it is enough to drive. ”

"Hahaha, okay." I excitedly said, "It's not enough, but you've done a great job!" Tao Yao too! I want to reward you well! ”

The man smiled honestly and said: "The honorable driver said that he laughed, and the master said that doing things for the court is doing things for his own family, and he should do his best!" ”

I nodded with satisfaction and instructed Li Si: "Li Xiang, pay the Ba Shi at double the market price!" ”

Li Si arched his hand and said, "Yes, Your Majesty." ”

The man was surprised, and hurriedly arched his hand and said: "It turned out to be the emperor of our Great Qin, and the villain was disrespectful." The villain is just a delivery person, and when he goes back to the head of the house, he will go to visit the prince in his own account room! ”

I said three times in a row: "In that case, you can go, I will let people reward you!" ”

After the man retreated, I looked at the three truckloads of goods pulled in, and did not forget to teach the three of them: "Look, as an important minister of the court, you are not as conscious and neat as a businessman!" ”

The three of them were embarrassed.

Looking at the expressions of the three people, I don't care if they listen to it or not: "Zhou Qi, start making gunpowder immediately." Li Xiang, Zhang Han, I will give you two more months, you must find ...... Like such a cart of stone flow yellow and saltpeter, no less than ...... Four cars! ”

It is estimated that there are more than ten carts of bombs that can be made by five carts of Shiliuhuang, which are definitely enough to blow up the Huns and Huqi!

With Tao Yao's Shi Liuhuang here, the two of them were embarrassed to complain, and immediately responded.

"As for you......" I stared at the male input, it is indeed not easy to make a flintlock pistol, that thing is easy to explode if it is not done well, and it is easier to accidentally injure people than a bomb, after all, no one is stupid enough to carry a bomb every day to train and fight.

Gong Yi was conscious, and immediately bowed down and said: "Your Majesty, as long as the lathe is made, you will definitely be able to make a flintlock pistol as soon as possible." The principle of the flintlock pistol is already very familiar with it, and the minister will definitely be able to do it in half a year, half a year! ”

I nodded, within my acceptable range: "Go ahead and do it as soon as possible!" ”
