In mid-March, Brother Jiu returned home in a hurry, hugged Fusuni and threw it high, which scared Fusuni into exclamation.

"Master, what are you doing! Scared the concubine! Fu Suni said angrily, and punched Brother Jiu on the arm.

A few girls covered their mouths and chuckled, and carefully retreated, leaving space for the two masters.

Brother Jiu hugged Fusuni excitedly and said, "Fu'er, it's done, the cement you said is successful!" ”

Fusuni's eyes lit up in surprise: "Really succeeded?" That's great! ”

It turned out that Fusuni and Jiu Elder Brother talked about natural disasters every year in the Qing Dynasty, and said that many natural disasters were caused by environmental destruction.

However, traffic is a big problem.

At that time, although Fusuni jokingly said that with her teleportation array, there was no need to worry about the circulation of materials.

However, the reality is that the number of teleportation arrays in Fusuni is limited by the level, and it is impossible to build too many. Even if they really build so many, it is impossible to spread it, unless they monopolize the circulation of materials throughout the country, but in this way, they are afraid that they will become the public enemies of the powerful in the country!

So, Fusuni came up with a way to build a road!

The roads of the Qing Dynasty were ordinary dirt roads, which were fine on sunny days, but when it rained, the roads were muddy and difficult to walk.

The official road is slightly better, smoother and wider than the normal road, with some gravel. But on the whole, it's still one word - rotten!

With such transportation, how can materials be circulated?

So Fusuni sacrificed the Crossing Artifact...... Cement!

Fusuni's journey through her previous life is not in vain, although she doesn't know the specific production method of cement, but the principle is still clear, that is, limestone and clay are used as the main raw materials, and you can calcine them into powder in a kiln.

As for the specific ratio, firing a few more kilns will naturally be figured out!

After moving, in addition to going to the household department and Wenyuan Pavilion every day, Brother Jiu spent the rest of his time on the research and development of cement.

Yesterday a kiln was fired according to the new ratio, and paved a road after mixing water and sand, and after drying today, the effect came out at once.

"It's really the same as Fu'er said, it's obviously water and sand, plus the powder from the stone and clay, after drying, it is smooth and hard, and it is no different from the bluestone ground, it's amazing!"

Fusuni was also too happy, the cement road was out, is the grass road still far away? In the future, when you travel, you don't have to be shaken like before, and your butt hurts!

Of course, in addition to being convenient for travel, Fusuni also did not forget to point out the role of the cement road in the territory of the Qing Dynasty.

"Master, don't underestimate this cement, think about it, how big is the difference between the walking speed of carriages and horses on the bluestone ground and the walking speed on the official road? If the cement road is built throughout the country, not only can the circulation of materials be greatly improved, but the decree of Khan Ama can also be issued to various provinces earlier, and even the army can go to various places faster! ”

Fusuni channeled her spiritual power into her vocal cords, giving her voice a hint of seduction.

"Master, although the size of a country's territory is inseparable from the country's economic prosperity, political clarity, and strong army, what is more important is the time it takes for the government order to be issued and the time it takes for the army to go to the place. If this time is too long, then it is not within the effective rule of the state. ”
