Zhu Yuanzhang, Taizu of the Ming Dynasty, announced in the 28th year edition of Hongwu's "Emperor Ming Zuxun" that 15 overseas countries such as Korea and Japan would be listed as "countries that do not levy", and warned future generations not to arbitrarily levy them.

The fifteen kingdoms were Korea, Japan, Great-Ryukyu (present-day Okinawa), Lesser Ryukyu, Annam (present-day northern Vietnam), Chenla (present-day Cambodia), Siam (present-day Thailand), Champa (present-day southern Vietnam), Sumatra, Western (present-day Coromandel coast), Java (present-day Java Island), Huheng (present-day Malay Peninsula), Baihua Kingdom (present-day northwestern Sumatra), Sanfuqi Kingdom (present-day Palembang, Sumatra), and Boni Kingdom (Brunei).

If you look at the map, because of the ground, some small countries on the Western side of the Ming really haven't thought about it.

At least Zhu Di didn't think about it.

Because it's not easy to manage.

But Indochina is different.

Bordering Daming!

Maybe Zhu Di hadn't thought about it before, but since Dusk said it in his ear so many times, he had this idea, how can he compare with his father's martial arts?

Lay down the entire Indochina Peninsula, probably enough.

If you clean up Mobei again, it will be exceeded.

If you clean up Yili and Timur by the way, then you can compare with the Qin Emperor and Han Wu, with the temperament of the Yongle Emperor, since there is such a possibility, how can you not operate.

With Zhu Di's will to go to Yingtian, the Daming Jinggi side began to be restless.

The generals after the Jingyan are actually still willing to fight.

Time flies.

At dusk, on Yingtian's side, there was a problem.

The Fuyao Hall is making good progress, and soon there will be three or four hundred talents gathered, after all, if you register in the Fuyao Hall, you will have one or two pieces of silver every month, which is equivalent to a showman, who doesn't want to go to this good thing?

Even several of them who are good at construction have been recruited by Huawei Real Estate and Cement Workshop High-tech, with high salaries, and their lives are more nourishing than those of Xiucai.

But there was gradually opposition from Suncheon's side.

Mostly from readers.

Because many scholars in Shuntian found that in addition to the fifty Luodi Xiucai who were hired as professors to teach the staff of the Fuyao Hall to read and write, it was difficult for other Luodi Xiucai to register in the Fuyao Guild, and there were only twenty or thirty people, and among these twenty or thirty people, there were those who were good at Western dialect, those who were well versed in astronomy and geography, and those who liked to study strange and obscene skills - in short, they were all "not professional" readers.

On the contrary, there are all kinds of talented people who are good at writing articles, and they don't want any of them in Fuyao Hall.

To explain in the words of Zhang Yao, Lin Zhendong and Jiang Nan, the directors of the Fuyao Guild Hall, you are talented people who are good at writing articles, and you are talents who govern the country in the court, and you should go to the department to report and serve the country, and you can't delay here.

That being said, everyone is still jealous of the pie of one or two silver a month, not to mention that the dignified scholars are not as good as the plasterers, carpenters, and blacksmiths of the lower riba people?

It was the voice of criticism that gradually rose.

Dusk ignored it.

just secretly asked Zhu Di to send the elite of Ying Yangwei to secretly defend the Fuyao Hall, beware of some scholarly families making conspiracies to attack the Fuyao Hall.

So the Fuyao Hall is not a problem.

At present, there is no problem with turning into real estate, the early stage is to repair the mud rammed community, the technology and capital are no problem, and the design drawings are mostly in accordance with the traditional way, which has been gradually running.

The problem is on the cement mill side.

The blower can be used, and the temperature of the processing can be reached, but it has not been able to meet the demand, and the evening has been inspected, and Lin Zhendong and other masters have carefully discussed for a few days and nights, and the answer has been drawn: the ore crushing is not fine enough!

The crusher is made by using the principle of grinding discs, limited by the material and process level, the ore raw materials crushed by this crusher are still the size of soybeans.

It's too big to meet demand.

Dusk spent a few days and nights thinking about it, and felt that it was necessary to work on the polo mill.

The ball mill can be crushed more finely, so as to meet the industrial requirements.

But there are too many technical problems in this area: the power unit, the transmission device, and the strength of the crushed parts are all blind spots in the knowledge of Dusk, and the principle can actually be speculated.

The cost of the power plant, if it is powered by manpower, will be extremely high.

To use electricity.

However, the manpower generation can't bring the motor, not to mention the twilight can't get the motor, he is just an ordinary person who graduated from college, not a technical master.

So the power can only be considered hydraulic.

Ditch the electric link.

The strength of the casting of the transmission device and the crusher involves the technical problems of annealing, quenching and special steel, the annealing and quenching is simple, there is an old blacksmith master, and it is possible to meet the demand for more experiments, but the special steel is a little difficult.

Even if it's difficult, you have to do it!

At dusk, he found Zhu Di, and asked for a large piece of land near the river on the outskirts of Suncheon City, and established two large workshops, one for steelmaking and the other for developing ball mills.

Then I went to the Fuyao Hall and recruited the blacksmiths, the masters who were good at making waterwheels, and the masters who had worked in the mining farm for many years into the newly built ball mill workshop.

A respected master was selected as the leader of the research team, and then the ball mill R&D team carefully discussed, and under the impetus of everyone's brainstorming, there was a preliminary idea.

On the steelmaking side, Dusk asked experienced blacksmiths and mining masters to cooperate to find a way to add special elements to ordinary steel - in fact, Daming's steelmaking level is at the forefront of the world, but it still has not reached the level of melting steel into molten steel, so there is still a technical problem to be solved.

Dusk can only let them experiment.

Because steelmaking is a national strategic plan, this steelmaking plant is ostensibly under the name of the Ordnance Institute, and Zhu Di will also transfer people from the Ordnance Institute, but in fact, it is still Dusk who pays alone.

There is only so much Dusk can do, all he can do is pile up with money, and the rest of the technical problems are all up to these craftsmen!

You can only count on these craftsmen.

The research and development of ball mill and special steel is in progress, and the research and development of cement cannot be stagnant.

First, use the crusher designed according to the dusk to crush the ore into the size of soybeans, and then use the pestle nest away from the production of a batch of crushers, and then use the manual way, the principle of leverage, with a large round hammer, with the help of gravity secondary crushing, and at the same time there is a backup plan to produce a batch of small stone grinding grinders, just like grinding soybean milk, the ore the size of soybeans is crushed into powder.

At the same time, experiment to see which solution can meet the needs.

Problems always have to be overcome.

As long as there is money to take, the people in the cement workshop have the spirit to continue, and everyone respects the dusk and is willing to dedicate to it.

Industry is gradually sprouting in Daming.
