"Of course, prepare the horses. The pen "Fun" Pavilion www.biquge.info" came back to his senses, Xiao Ming shouted loudly.

The graphite mine has been found, and the limestone mine has also been found, although the mine has not yet been established to form a systematic production, but it is still possible to mine some in advance.

However, only a part of the mining is carried out, and Xiao Ming also costs a lot of money, and the people who are transported back and forth in this mining need to be given silver.

That's why Xiao Ming is so eager to cooperate with Liang Dahai this time, as long as there are a large number of slaves, mines, and workshops, there will be enough manpower, and then he will select some young and middle-aged people among the slaves to carry out the transmission of various technologies, and gradually build the industrial base of Qingzhou.

One master and one servant, the two of them went out of the Qi Palace, and now Xiao Ming went to the Governor's Mansion to supervise the implementation of various decrees, and the most he did was to go to the Equipment Division.

In the equipment department, Chen Qi is correcting the production of the crucible steelmaking assembly line, and the technology is available, but there will still be deviations in specific production practice.

During this time, Xiao Ming focused on cultivating Chen Qi, and Chen Qi got the most technology transmission in this science and technology spar.

The reason why Xiao Ming does this is very simple, that is, to prevent the leakage of craftsmen's skills.

It is more insurable for ten people to master the ten parts of a set of technology than for ten people to master all the technical processes.

Moreover, the equipment department has also formulated strict technical confidentiality measures, and if one person leaks secrets, the craftsmen on a production line will be punished.

In the Great Chongqing Kingdom, craftsmen belonged to lowly households and had a very low status, and in order to prevent craftsmen from making weapons privately, the household registration of these craftsmen was made into a separate artisan register, which was supervised by the government.

Controlling these people in and out of Qingzhou is a very simple matter.

"Your Highness, these are limestones." In the backyard of the Instruments Division is a pile of gray-white stones, these are limestones.

In modern times, limestone is not only a necessity for the production of cement, but also a necessary solvent in blast furnace ironmaking, limestone can effectively remove sulfur and silicon impurities, improve the quality of iron, and prevent subsequent steel from becoming brittle.

Xiao Ming went over and looked, these limestones were piled up into a two-meter-high hill, and the limestone was relatively large and of good quality.

The two blast furnaces were working at the same time, with four workers taking turns using blowers to blow the blast furnaces, and some craftsmen poured iron ore, coke, and limestone blocks into the blast furnaces.

The red molten iron flows from one blast furnace to another, and finally the wrought iron flows into crucibles that are assumed to be on a one-meter high shelf, and when one crucible is full, the other crucible is replaced by another.

This efficiency is still 108,000 miles away from modern times, but compared with the previous steel filling method, this is already mass production.

And the formation of high-quality molten steel will be used by different craftsmen to make farming tools, machine tool parts, briquette furnaces and other things.

Chen Qi was instructing the workers to collect the slag at this time, which Xiao Ming had taught him.

Seeing Xiao Ming observing the steelmaking process, he wiped the sweat on his forehead and said, "Your Highness, you said that I will collect this slag after adding limestone, and now there is a lot of this slag, but what is the use?" “

"This slag is a good thing, and it can be used to produce a very powerful material." Xiao Ming said with a smile.

Xiao Ming hadn't told Chen Qi about this knowledge yet, Chen Qi was curious: "Your Highness, this slag has come out, just tell me, otherwise I probably won't be able to sleep again at night." ”

Xiao Ming laughed twice, "Actually, in addition to making iron, this limestone can also be calcined into a material - cement!" Because the slag contains a lot of cement, it can also be used to calcine the cement, so you can collect it so that it is not wasted, otherwise it would be a pity that the slag is discarded. “

"Cement." Chen Qi and Qian Dafu glanced at each other.

Now they are no longer surprised by the strange words that popped out of Xiao Ming's mouth, and they don't know where this prince learned these strange knowledge.

Xiao Ming and the two stood aside, and the knowledge in the science and technology spar was instilled in the minds of the two, and after explaining it, the two of them knew what cement was and what its function was.

"Your Highness, if this cement is used to build city walls and pave roads, wouldn't it be invulnerable." Chen Qi was surprised.

"No, cement is still the most basic thing, and what is made of concrete is really invulnerable." , and then Xiao Ming told Chen Qi about the concept of concrete.

"......", Chen Qi can no longer describe his shock in words, he said: "Your Highness, if the walls of the Great Yu Kingdom are all built of concrete, then the barbarians can only **** outside the city walls." ”

Xiao Ming smiled: "Now you think a little too much, although this concrete and cement are magical, but with our current production speed, it is good to be able to meet our own use." ”

After being excited for a while, Chen Qi suddenly became a little decadent, and he said: "Your Highness, now you have taught me too many things, but you look at this equipment division, there are too few craftsmen, but this little work is no longer busy, and it is estimated that there is no manpower for this calcining cement." ”

During this time, the Instrument Division recruited some craftsmen, and the number of craftsmen in the Instrument Division reached fifty, but it was obviously still not enough, and he couldn't help but feel a little helpless, "I'll figure out a way to do this, take your time, and produce as many things as you can." “

Chen Qi nodded helplessly.

This time, Xiao Ming came over, one was to check the application of limestone and graphite in ironmaking, and the other was to let Chen Qi understand cement and prepare for subsequent production.

As the saying goes, if you want to get rich, you must first build roads, and the smooth flow of traffic can greatly promote production, and because of the characteristics of the people in this era who gather in the city and live, there is no need to build roads like modern times, hundreds of miles at every turn.

The application of crucible ironmaking has matured, and now graphite ore and limestone ore are only in the hands of Xiao Ming, which is equivalent to his monopoly on crucible steelmaking technology.

However, the lack of labor is still his shortcoming, and the current equipment department is generally a small fight.

Thinking of this, he could only increase his investment in Liang Dahai, every year the Great Chongqing Kingdom would be plundered by the barbarians, and many people became the goods traded between the barbarians and the Great Yu State, and many smugglers were active in the slave trade between the Great Yu State and the barbarians.

For slaves, his first choice is naturally the people of Dayu, as for the slaves outside the territory, they can basically only do some hard work, after all, it is also difficult to communicate in language.

After staying in the equipment department for a while, and instructing the craftsmen on the details of steelmaking, Xiao Ming and Qian Dafu went back.

Halfway through, suddenly a man riding a horse suddenly came out of an alley and blocked him, but it was Wang Shijie.
