The most important thing in a cement plant is lime.

Lime is, of course, mined from limestone. Luckily, most of the three parallel mountains of the Crimean Mountains are limestone. And most of the mountains in the rest of the Black Sea are not limestone, so good luck.

Qiao Bao took 200 Slavic male slaves into the mountains on the west side. These Slavic male slaves were taken down by the navy of the Han Kingdom, either explicitly or implicitly. The Han Kingdom, which was in dire need of population and labor, also had to take advantage of the good relations with the Genoese to do some subordinate means to obtain what it needed.

After being rescued, they had to sign a treaty to work for the Han kingdom for three years. Otherwise he will die. And of course they are happy to do this, otherwise they will have to go overseas and suffer for the rest of their lives.

Carrying a pickaxe on his back, Qiao Bao searched for a more vivid limestone at the foot of the mountain.

Soon, he found a mine.

"This is it! Come on! "Two hundred men took out their picks and worked hard to mine the limestone.

The craftsmen went to Xin'anwei, where the Han people who cultivated soon brought food that the craftsmen paid for. Xin'anwei was only a three-hour drive from the Crimean Mountains, and in view of the friendly attitude of the Karaim, Qiao Bao took it upon himself to have the Han Chinese and workers put their temporary food and accommodation in the Karaim fortress. Meals still depend on Xin'anwei, and then Qin Chang'an will allocate the extra payment to Xin'anwei on a monthly basis.

Lime is a very simple process. The most primitive only needs to be separated from the charcoal and weeds, and baked in a double layer for a few days. In order to save time and effort, there was a lot of wood here, so the craftsmen and workers simply built a charcoal factory and ran it together with the lime factory.

If nothing else, the lime has not yet begun to be ready, and the charcoal is selling very well in the Karaim fortress. This has to be said to be an accident. It was the first time for Qin Cang to see a factory that made a profit in the first month of work before it produced products.......

The fortress inhabited by the Kara'im was originally prepared for war. So the rooms were made for war. The Karaim people can only sleep on the floor! Without the bricks trafficked from Chizhou, Lemar's prestige would have been reduced by the rapid growth of the population.

After a large number of refugee shed-like structures were simply built out of bricks, the Kalayim fortress became a fortress on the inside, and a large circle on the outside was like a refugee camp.

People live in semi-underground 'rabbit holes', and they have to eat on the ground. Whether it's a cold rabbit hole or a cramped environment inside the Kalayim Fortress, charcoal is needed for heating. So charcoal sells surprisingly well in the market of this place!

The incredible Qiao Bao is ready to recommend the cement plant's products to the possible future Karaim Gonglemar. Painting the walls with lime will make the interior much brighter and more comfortable. Those dark stone bricks and almost non-existent windows will strike fear into the hearts of everyone who comes here.

A week later, the first lime has been successfully produced. There is no shortage of water and grass here, there is no shortage of charcoal, and the quality of lime is also good.

It should be noted that such a yield is obviously not possible. A shelf is less than 20 catties when put away, and more than 30 shelves are burned to less than 600 catties, not half a ton! The lime process also needs to be improved.

Qiao Bao left the lime in the cement plant. Next, he will not only make lime, but also build a cement kiln. The difference between a cement kiln and a brick kiln is not so big, and the production volume is also very large. According to the preliminary forecast, three or four tons of cement in one kiln should be no problem.

The remaining lime was used for the construction of the new plant. With the newly arrived red bricks, Qiao Bao soon built rows of bright and beautiful houses at the foot of the hill northwest of the Kalayim Fortress. The Slavs were then driven to build a high wall, and a complex of buildings resembling modern factories was born.

The dust from the kiln is very serious. If you work too much in a place like this, your lungs will be very devastating. Qin Cang was okay, and took out the precious wool to make masks and distribute them to the Slavs. But these guys secretly removed the masks and stuffed them into their clothes. When questioned by the craftsmen, their answer was simple: "How can such a precious fabric be made into a mask?" We are grateful for the King's gift, but we cannot waste it. ”

It has been said that the poorer you are, the more willing you are to spend your body to get resources. Moving bricks is also the same, and so is part-time work.

The wind of time blows into July.

The hottest season did not exceed 30 degrees. People still work on the site in single clothes. Especially these Slavs, who according to themselves, were from Ryazan, and they were too hot to be shirtless.

The latest kiln of cement came out, and people brought out these dusty guys, surrounded them with coarse cloth from Chizhou, and put them on horse-drawn carriages. A cart of cement has 500 catties. Dozens of miles of horse-drawn carriages quickly set off from the cement plant. Some of them were cheekily bought by Lemar at the fortress of Karaim, and then they would stop at Desheng County and go to Yanjian in three separate groups, the Tatar settlements in the south, and Chizhou. Finally, a part of it was set aside from Chizhou to reach Linhai County.

Cement and lime were suddenly fashionable on the peninsula. Freedom from the threat of war, it is clear that more habitable building materials are being appreciated.

It is difficult for ordinary people to afford the price of cement lime. These unscrupulous things have been speculated on the black market at a sky-high price of one gold coin per ten kilograms! It's almost a money grab!

Who knew that Kanglado also sent a letter to Qin Cang, sending someone to take several wagons of cement from the cement factory. This further fueled the determination of a large number of local tyrants in Kaffa to compare. They sent people waving bills and crowding outside the lime factory to buy white lime and cement. Lime can paint the walls, while cement saves them from having to build a house with heavy and bulky stones. There are also bricks from the brickyard. Together, these three items brought Qin Cang more than five thousand pure benefits to Hai Peilun in the entire month of July!

Although he knew that this trend would soon fade, Qin Cang still breathed a sigh of relief.

After saving up for two more months, after the summer grain harvest, the new reclamation team will go to Mariupol to build a new town. The coal fields of Donbass are in sight, and the casting of artillery will no longer be just empty talk on paper.

"Khan, your daughter has sent a batch of precious gifts from the Han Kingdom."

"Oh, what is it? Cute saber? ”

"It's not. is a building material. ”
