The Summoning World of the Great Qin Empire

Chapter 973 Making Gunpowder
Fusu roughly remembered the working principle of the waterwheel in the past, but people in this era basically had only one manpower as the main labor force, even for pounding millet, it was still completely manpower, and even the graphite roller was made by Xu Guangqi In the future, this is what I thought of...

Speaking of Xu Guangqi, Fusu's eyes suddenly brightened, but he encountered a very depressing problem. It is winter now, and the sea has been frozen. It is impossible to call Xu Guangqi back from the enemy-occupied area directly. In this case, the risk is really high. It was too high, and for a talent like Xu Guangqi, Fusu would not be willing to die like this.

There are not many things to do in winter, even if there are some things to prevent snow disasters, they are all done by Fazheng and other six ministers, while Fusu devoted himself to the production of waterwheels.

It took Fusu more than ten days to make a sketch. Fortunately, Fusu could think of the rotating shaft as the axle, otherwise he would not know how to describe this kind of thing to Ou Yezi.

Ou Yezi looked at the sketch drawn by the emperor. Although he felt confused, he still had a general direction.

In half a month, the waterwheel was successfully produced!
The naturally flowing water can pass through a ditch directly from the moat. How to drag the huge hammer in the jack has also become a problem.

There is not much difference between the waterwheel and the waterwheel in Fusu’s impression. It can rotate quickly under the natural and flowing water, and can drive a very large force. As for how to use the waterwheel to mobilize the giant hammer to beat the iron plate, the monarchs and ministers are a little helpless .

In the end, the only way is to use the earth method, directly use the hardwood that makes the gun shaft to make a handle that can be shaken with the waterwheel and tie it to the windmill. It is directly nailed here. When the windmill is driven by water, turn it, and the handle will grow. The power of the car.

If it is in later generations, it may be necessary to do some calculations, but Fusu completely left it aside and went directly to the last step to see if he could move a huge iron block weighing a thousand catties. Putting it into use, in this way, Daqin soldiers can also wear the plate armor covering the entire chest, and their combat effectiveness can show a linear increase!
"Boom!"

"Boom!"

"Boom!"

Fusu was very satisfied watching the water wheel drive the huge iron block up and down for a while, causing the whole earth to shake.

"This matter is done, and the rest will be left to you!" Fusu laughed.

Ou Yezi and other officials cupped their hands one after another: "All this is due to the emperor's credit, and I dare not take credit for it!"

"Hurry up and deploy manpower. If you don't have enough manpower, go to Meng Yi to ask for it, and tell him that I said it. You can give as many manpower as you want, and put it into mass production as soon as possible."

"I obey the order!" Ou Yezi hurriedly surrendered his hands and accepted the order. He felt that this matter was not only serving the emperor, but also to a large extent to realize his ideals.

Soon, the first batch of plate armor was produced. Needless to say, the quality is very good. If a single arrow is shot, only one mark can be left on the plate armor within thirty steps, and the arrow will Get bounced off!

Fusu felt it himself. It should be that after the waterwheel replaced the manpower, the plate armor was subjected to a heavier force than the manpower beating during the forging process, and more impurities in the iron were smashed out, so in terms of density, It's already amazing.

The specific performance is the astonishing endurance. Fusu ordered the soldiers to thrust out this plate armor with their spears, which almost caused the soldiers' hands to bleed, and it took more than ten blows to pierce the plate armor.

Meng Yi watched from the side, and immediately thought of the emperor's report that this method of forging battle armor must not be spread. He suggested that this forging technology should be protected according to the protection method of white sugar and Qin paper.

Fusu nodded: "All technologies will be spread in the future, but this kind of technology must not be spread before the world is unified. You need to spend more time on this matter!"

"Don't worry, Your Majesty, this is a matter of my duty." Meng Yi said seriously.

Fusu is also very relieved of Meng Yi, and Fusu has one more thing to do next—that is to call gunpowder to come to this world in advance!

Although Daqin's productivity at this time is not enough to manufacture things like gun barrels in later generations, Fusu feels that making explosives should not be too difficult.

If there are explosives, some strong cities can definitely be easily breached.

This person really should come down and think about life first, so that he can think of many useful things. Fusu used to only think about unifying the world by relying on the summoning system, but after these years, he realized that unifying the world is far from as simple as he thought. Holding the summoning system in hand is definitely not an easy task.

Fusu returned to the palace and began to recall all the memories of his later generations. After holding back for several days, he finally got together several formulas of gunpowder, mainly potassium nitrate, sulfur, and the last one was charcoal.

But what the specific ingredients look like, Fusu is not very clear.

Sulfur is relatively easy to find, but Potassium Nitrate, Fusu can't remember very clearly, how did this kind of thing come from... Fusu almost tore off all his hair in the end, thinking of plant ash As for the two things, saltpeter, how to deal with them, Fusu was perplexed, thinking too quickly, Fusu would even slap himself twice, forcing himself to understand the knowledge he had learned at the beginning.

Salter, sulfur, and charcoal were quickly prepared in large piles according to the emperor's requirements.

When Fusu arrived in the arsenal, he saw that he was randomly piled up next to the big stove, his face turned pale with fright, if the natural mixture ratio of this thing reached, it might send the entire arsenal to heaven!
Fusu swallowed his saliva, and told people to separate all the things quickly, unless he needed them, and then put them all together, otherwise, these three things must not be mixed together!
Because he had forgotten a lot of chemical formulas, Fusu had to ask someone to fetch equal parts of saltpeter, sulfur, and charcoal.When mixing for the first time, Fusu used a certain proportion, and found that there was not even black smoke, and there was no reflection at all.

Fortunately, Fusu had enough resources, so I tried again. Maybe it was because of the different purity, and I managed to smoke and go off a few times, but then I did the experiment according to the same ratio, but there was no response. .

Fusu finally realized the problem of purity, so he ordered everything to be ground into powder, especially the saltpeter, which had to be finely sieved before it could be used.
