Out of the palace gate, I thought about it for a while, and said, "Meng He, go and call Li Si together." In addition, go and get all the saltpeter from Taoyao. ”

It didn't take long to arrive at the Jiangzuo Mansion, where Li Si was already waiting.

Seeing that Li Si was a little nervous, I smiled and said, "Li Xiang came fast enough." ”

Li Si hurriedly bowed down and said, "Your Majesty summoned you, and you don't dare to delay a little." ”

"Let's go." I walked towards the house.

Li Si followed beside him, was silent for a while, and then spoke: "Your Majesty, about the matter of the Xue Palace......

I waved my hand: "You are all for the country, there is no right or wrong, you are all loyal ministers." However, if you have an idea in the future, you can say it directly, and you don't have to say it through others. ”

Li Si hurriedly thanked: "Your Majesty, the minister obeys the order." ”

Feel a little at ease, Lu She's matter is indeed something he doesn't consider, everyone knows that Lu She is his close attendant, let Lu She open his mouth Isn't there no three hundred taels of silver here. However, he is also helpless, he rarely communicates privately with other people on weekdays, and in his opinion, the only person he can trust is Lu She.

'Alas, since he had already collided with His Majesty at that time, he should have spoken out at the court meeting, and maybe he could get the name of a direct minister. Now it's not human ...... inside and out'

Regardless of what he thinks in his heart, Gong Chuan is already waiting for me in the house.

I didn't sit down, and instructed: "Gong in, go and prepare a few clay pots of the size of the circle with both hands, and then prepare some stone flow yellow, charcoal powder with hemp stalks, and a zhang long twine, not too thick, prepare five or six sticks, in addition to the solidified grease, and then bring accurate scales and copper rights of one catty, one tael, and one baht." ”

Gong Yi bowed his hand and said: "Back to Your Majesty, there are not many Shi Liuhuang generals in the mansion, only one can, or those Fang Shi left behind back then, they are all placed in the general mansion, I don't know how much Your Majesty wants?" ”

"One can is enough, go get ready." The proportion of sulfur is not large, one can is enough.

After a while, Gong Yijin came over with a few people with things, and I looked at it to see that there was no problem.

"Let's go, go to Shanglin Yuan."

Gong Yijin glanced at Li Si strangely, although the status of the two was very different, but Li Si knew that I valued Gong Zhijin very much, and he was okay with his face, so he shook his head and said that he didn't know what to do.

Out of the mansion, the people sent by Meng He had already taken back the saltpeter, and there were three jars, all of which were sealed with mud. I nodded, it seems that the Qin Dynasty has really begun to use saltpeter, I didn't explain the details too much, the clay pot was sealed by themselves.

"Meng He, find another carriage, let one drive it, put these saltpeters in the other car, and stay away from my car. Be careful not to drive too bumpy. "I don't dare to put these three jars of saltpeter by my side, in case they explode, not to mention the death or injury, Fusu's appearance is still relatively handsome, don't be disfigured......

Li Si was startled, pointed to the jar and said in a panic: "Your Majesty, this is saltpeter?" ”

He still remembers the horror of saltpeter that I popularized to Feng Zheng and the two of them last time, but he didn't expect him to be so close to saltpeter, and he was scared.

I smiled and said, "What are you afraid of, it's not so easy to blow up, let's get in the car." ”

If pure saltpeter is so easy to fry, there is no need to add charcoal and sulfur.

Li Si glanced at the saltpeter jar suspiciously, and hurriedly followed it into the carriage, Gong Jinjin had obviously heard of saltpeter, and was not so afraid.

Not long after, the group left Xianyang City and arrived at a dirt mountain near Shanglin Garden, and Afang Palace was built in Shanglin Garden.

Looking up, the Temple of the Son of Heaven that was being built not far away had completed the rammed earth foundation and began to erect pillars, and a group of people were pulling a thick wooden piece of wood to the high platform.

With the help of pulleys, the manpower required has been reduced a lot, and more people are next to the brick kiln and mud, preparing the mud needed to fire the green bricks, and some burned green bricks have been piled up next to it.

Before the saltpeter came, I stopped at the top of the artificially built mountain, pointed to the Temple of the Son of Heaven in the past dynasties and said: "Li Si, after you go back, tell Bai Chong that the main building of the Temple of the Son of Heaven in the past dynasties uses green bricks, and Shinto uses stone as usual, but the road from the Temple of Heaven to Xianyang does not use green bricks, but uses red bricks instead." ”

Li Si arched his hand and said: "Your Majesty, it was originally planned to use rammed earth to build roads, do you want to change it to brick paving?" ”

I nodded: "I think that this Temple of the Son of Heaven will play a great role in rallying the hearts of the remnants of the Six Kingdoms, so everything must be done to the best." ”

"In that case, you can use green bricks instead, why use rough red bricks?"

I sighed softly, "If possible, I would like to use stones, but how much food and manpower will be costed. Red bricks are more convenient to make, although they are not durable, and they are paved once every two years in the future, and the effect is the same if there are more layers. If Great Qin can really achieve the prosperity and strength I imagined in the future, it will not be too late to rebuild. ”

Li Si praised: "Your Majesty's heart is the head of Qian, and the ministers can't hope for it." ”

"In addition, you discuss with Bai Chong, now that the land in Xianyang City is not enough, I hope to choose a piece of land outside the city and start a new Fang City. The road in Xianyang City should also be repaired, and the envoys from the Western Regions may come next year to show the prestige of our Great Qin. ”

Li Si arched his hand and said: "Obey, what Your Majesty hopes for is exactly what the emperor wants to do, the emperor has already planned to expand Xianyang City, but Lishan and Afang Palace employ a lot of people, so they can't make the trip." ”

"The city does not need to be expanded first, the Xiongnu are far away, the four seas are stable, Xianyang has no major threat, and the official offices are also in the city, so solve the problem of land use first. If the experiment is successful, the city walls will be of limited use. ”

My plan is to expand Xianyang according to the idea of Geng Gong to develop Datong in the future, and build a two-axis twin city. This timeline Weishui passes through Xianyang City, the area is larger than in history, to the south is the Qinling Mountains, there is no threat, you can build a new city in the south, if you renovate the old city, the cost is too great. When the time comes, the Shanglin Garden will be dismantled, and the Temple of the Son of Heaven is located in the center of the axis, and the overlook is more perfect.

Li Si was a little curious: "What does Your Majesty want to test?" Can you threaten the city walls? ”

I smiled, and was about to start speaking when the wagon carrying saltpeter was slowly approaching.

"You'll find out in a moment."

The carriage approached slowly at a very slow pace, for fear of blowing up the saltpeter. By the time we got down the mountain, a few of us had already picked up a bunch of bits and pieces.

I said to a few craftsmen: "Let me explain the concept of percentage first, for example, saltpeter, charcoal, and stone flow yellow are mixed together to add up to 100 catties, then the proportion of 78 catties of saltpeter is called 78 percent of the mixture, if saltpeter is 50 catties, then it accounts for 50 percent, you can understand, right?" ”

Gong Yijin thought for a long time and asked, "Your Majesty, what if the three of them add up to less than a hundred catties?" ”

I patiently explained: "The concept of percentage is to divide something into 100 parts, and then the proportion of something in it. ”
