Cement is what Ye Chunqiu cares about the most at the moment, because the magic of cement lies in its ability to smooth the road surface. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

In this era, although the carriage has appeared for thousands of years, it is still not popular enough in the transportation of dignitaries and even many goods, not because of the cost, the fundamental problem is the road, because of the unevenness of the road, even if it is an official road, it is only paved with gravel, which leads to the comfort of the carriage is reduced to a minimum, and those who can afford to sit in the carriage, who is willing to endure the violent shaking of the carriage all the time? If you encounter a big pothole, it is enough for the whole person to bounce up in the car and hit the head full of bags.

Therefore, the most convenient carriage has become a despised means of transportation, which is not counted, and because of the desire to avoid bumps, the carriage often does not go fast, and the result is that the person sitting in the carriage is even slower than the sedan chair, and because of this, the vast majority of the official family would rather hire manpower to sit in the sedan chair, but not that everyone enjoys the so-called 'privilege', it is really a last resort.

The same is true for using a horse-drawn cart to pull goods, if there is too much load, the road with potholes is difficult to pull up, and as a result, once it is deep in the mud, and I don't know how much effort it takes to pull it out, it is not as convenient as using a man-powered cart.

It is precisely because of the problems of the road that the use of horse-drawn carriages is not widespread, and the horse-drawn carriage technology of the East is far behind that of the West, which is why Ye Chunqiu attaches great importance to cement.

With cement, this smooth and mirror-like road can reduce bumps to a minimum, greatly improving the comfort of horse-drawn carriages and road transport capacity, and laying a good foundation for the transportation of goods in this economic development zone in the future.

With the road, the next step is to improve the structure of the carriage, the original wooden structure, can be appropriately replaced by rolling bearings, not only to increase the speed of the carriage, but also to work on the load capacity of the carriage.

These plasterers carefully took the shovel blade to smooth the cement poured into the roadbed, and the cement concrete is made of fine sand, and the shovel blade shoveled, and it was immediately smooth like a mirror.

After a few days, a section of several hundred meters of road was finally completed, and this is only the early test section.

After the sun came out, the entire cement road had already hardened, so Ye Chunqiu ordered someone to pull the carriage and let the carriage walk back and forth on this section of the cement road.

At present, Ye Chunqiu has made a long list of workshops, in addition to the clock workshop, steel workshop, carriage workshop, and cement workshop that are still in the plan, the most popular one at the moment is a secret workshop specially set up by Ye Chunqiu, the workshop is very small, only seven or eight people, more like a small laboratory, they mainly make gunpowder.

For the current black powder, Ye Chunqiu is not very interested, because of the production needs of crystal workshops, as well as the construction of cement workshops, roads and town mansions, mining has become the biggest problem for suppliers at present, and a large number of manual mining ore is time-consuming and laborious, and the difficulty is not small, so if you want to open the mountain and chisel stone, the best way is to use gunpowder to blast it.

Ordinary black powder is not easy to preserve, and it is a forbidden object of the imperial court, and the stability is also very poor, not to mention that the power is too small, and it is useful to deal with ordinary mines, but when it encounters rocks, the effect is minimal.

Therefore...... Whether it is for the new army of Zhenguo or for the needs of other workshops, a new type of gunpowder must be produced quickly, Ye Chunqiu specially hired a group of craftsmen, and after signing a contract with them, he began to develop it secretly.

Ye Chunqiu has very high requirements for this kind of gunpowder, on the one hand, it is stable, otherwise once there is a collision or improper storage, there will be a BAOZHA accident, wouldn't it be a hell?

In addition, it was required that its power was much stronger than that of black powder, and in the end, Ye Chunqiu chose ********.

It was developed by Nobel Prize three hundred years later, and it is a very powerful explosive, but because it is very sensitive, it will be BAOZHA when it is shocked, impacted and cremated, and it is very dangerous, so it lacks practical value.

Think about it, what will be the consequences of a bottle of ******** that looks inconspicuous suddenly explodes just because of carelessness, and it is ten times more powerful than black powder?

Ye Chunqiu could almost not think about it, this was death.

However, after that, Nobel found that the ******** will become very stable after adsorption with diatomaceous earth, whether it encounters an open flame or a collision, it will not produce BAOZHA, so the problem arises again, don't let you explode, lightly collide, you have to explode, but now it's okay, when you explode, you are dead, and you don't explode.

Well, ******** is actually good to refine, and there is no shortage of diatomaceous earth, so Ye Chunqiu must come up with a detonation device-****.

Since the cement road was paved, it is located in a temporary building in the Zhenguo Mansion, which is surrounded by high walls on all sides, impermeable, Ye Chunqiu's secret laboratory is set up here, and at this time, Wang Shouren came here with a few new soldiers of the Zhenguo early in the morning.

Xu Jie, who came with Wang Shouren, didn't know what was going on, only knew that the palace counselor took him and a few colleagues here, there were four high walls here, but there was only a small doorway, and there were special people at the door to inspect, and when they passed the doorway, they saw Ye Chunqiu wearing a unicorn suit and a few craftsmen muttering something, Xu Jie and a few people hurriedly stepped forward to salute.

Ye Chunqiu looked at them with a smile and said, "Please try a new thing today, well, there may be some dangers, if you don't want to, you can quit." ”

Xu Jie and the others stood still, without the intention of retreating in the face of difficulties.

Wang Shouren was actually confused, but looking at Ye Chunqiu's serious appearance, Wang Shouren couldn't help but be a little worried.

I saw that in the middle of the high wall of a few acres square, a big pit was dug in the middle, and the big pit was two feet deep, and in the corner of the wall, a pergola was built, and several craftsmen carried pens, as if they were recording and discussing something, but other than that, there was nothing.

Wang Shouren and Ye Chunqiu arrived at a corner, and couldn't help but say: "Chunqiu, what is so dangerous that you have to let Xu Jie and them do it?" ”

Ye Chunqiu replied simply and clearly: "Gunpowder." ”

Gunpowder......

Wang Shouren was relaxed, he had been to the border town when he was young, and he had an understanding of the gunpowder used by the Ming army, what about this thing...... Well...... OK.
