Zhang Guoan, the owner of the island, carefully read the reports of the two of them, and he didn't care about their gains...... Goryeo is too poor, and this may be one of the reasons why they have always been able to avoid annihilation??

He looked at the process and results of the battle, as well as their understanding, and felt that his influence on the half-sized children was still quite large, and he did not cultivate them in vain. Pen & Fun & Pavilion www.biquge.info

Very well, that's it, let the branch of the Sambetsu army grow bigger in secret, so that the Tatar bandit group will not be at peace in the northern region, they can't care about it there, otherwise they wouldn't have sent troops to attack Goryeo nine times in succession.

He recognized the proposal of the two captains to increase the supply of their arms, and he would also increase the supply of food, and they could take the initiative to attack Hepucheng, which was a real vote.

Jeju Island and the Bangyo area of Shandong Province have successively sent male and female laborers, which not only balances the proportion of the Badaohe area in terms of gender, but also makes the geographical characteristics of the labor force diverse in terms of origin.

Although the owner of Zhang Guoan has accelerated the speed of development, he waved the banner of commerce and trade, and used profits to attract others to come, but even in the Great Song Dynasty, which claimed to have the freest movement of the people, the population flow here was not satisfactory, and the population was still too small.

Of course, he must admit the gap between the times, compared with the fact that there were roads to walk in the Yuan and Ming eras, Zhang Guoan was already secretly happy.

To be honest, he was really worried at first that the Great Song Dynasty government had taken a fancy to his development and suddenly wanted to be nationalized...... Over time, however, he discovered that the Great Song was indeed a government that never inhibited land annexation and recognized individual private property rights.

And when the merchant and the government are in a lawsuit, they can even let the merchant win. All of this put him at ease.

As for the Lu family group, they did not rely on their own strength, so they had bad intentions and wanted to use robbery to solve the problem, and they could also pay 10% of the customs tariff according to the agreed conditions.

Zhang Guoan, the owner of the island, felt his cautious eyes...... Otherwise, he wouldn't always be able to integrate some other types of people as a team member.

But. He is still firmly developing in the direction of a hodgepodge and does not follow a single one.

He had to start recognizing the slave trade, and when he came, he was a slave, and when he came to him, he didn't have to treat them like slaves, right?

As a result, now, the frequency of the Great Song Dynasty people is still the same, and there is no way to speed it up, but there are more whites and blacks. Of course, the quantitative level is not the same.

Captain Guo Beyu's Halong Bay actually sent personnel at this time, and these were all prisoners.

When the black pikes were trained, Zhang Guoan sent them there as soon as possible...... Although it is a sparsely populated place, it is the land of other people after all, and at this time, the Jiaozhi people are not very kind to the Great Song Dynasty.

However, he needs coal. The more the merrier, and the firing of cement accounts for the lion's share.

A river of coal in the area. It is more suitable for firing into coke, which is reserved for steelmaking and ironmaking.

The gang of pirates who turned into regular ones on Zhenming Island at the mouth of the Yangtze River have not found coal mines in the Huainan area until now, so coal is the first thing that restricts the development of the Badaohe area.

There are also coal mines in the Ezhou area, but they are too small...... After the Lu family group pulled into the power of Ezhou City and Jiangling City. Although it was suppressed by civil officials and seized the distribution right of cement in the form of state monopoly in the name of prohibition, the Great Song Dynasty government did not fail to give returns. For example, it is exchanged for salt quotation or other non-hard currency.

When the people in charge of Ezhou City found that there was an urgent shortage of coal here, they of course remembered the coal mines, and asked if they could exchange the coal for some goods here...... Of course, the owner of Zhang Guoan was willing, and he also gave a price that seemed very suitable to the other party, which was higher than the price he offered to the government of Annan.

As a result, the white cotton in the Xiangfan area and the black charcoal in the Ezhou area were sent to Liuqiu Island along the Yangtze River.

Of course, people are still profitable.

In this way, it is far from enough, because Zhang Guoan had to put on a steam boiler.

This steam boiler is low-pressure and the oldest of its kind.

Zhang Guoan was designed as a cylindrical fire-tube boiler and called it a shell boiler.

The structure of this kind of boiler is simple, and the whole boiler body is composed of the shell, the head, the front and rear tube plates, the fire tube and the furnace bladder.

In this way, it is possible to take advantage of the craftsmanship of the craftsmen of the Great Song Dynasty.

In order to be safer, he also built the outside of the pot shell with a furnace wall, and the furnace was cast into a wavy shape that could withstand a certain amount of thermal expansion.

Zhang Guoan tested the thermal efficiency of this internal combustion boiler is only about 55%, and the evaporation rate is less than 30kg/(m2.h).

However, it has small fluctuations in pressure and water level during operation, large steam space, less steam with water, good quality, and low requirements for water quality, and if you add a hydraulic blower, its flue gas resistance is small.

Of course, the most important thing is the simple structure.

Even the director of Hu Zhenbei can see its structure...... Isn't this just a large teapot with a shell?

Zhang Guoan, the island owner, gave him a blank look and said, "Then why didn't you get it out earlier?!" ”

"If it's just for boiling hot water...... You don't need to go through that hassle, do you? ”

After they were casting, they spent a lot of time to close the pipeline, in addition to the precision of the parts, they also used the method of copper and tin soldering...... The result can only be low pressure.

Even if it is a low-pressure type, they immediately show a big effect.

Don't look at it, there is no problem with bringing three distillation kettles at the same time, and the distillation is better and faster.

The production of alcohol, camphor and perfume increased all at once.

Director Hu Zhenbei immediately understood, he nodded to show that he understood, wouldn't it be better if it was bigger? !

"There's no need to use the precision casting method, in that case, the so-called furnace is not big enough, I'm a talented person, I can rivet it."

As a result, it failed the first time, and the sealing did not work well...... He had no choice but to think about it honestly with the other great craftsmen.

The boiler is very useful, so he needs a lot of fuel...... Only using charcoal, it's really distressing, this is also a bestseller in Da Song, as long as it is cheaper, it will be snatched up immediately.

Therefore, the coal economy, he must develop, even if it is a war with other countries!

When Captain Guo Beyu took the hired labor force to develop Halong Bay, more than half a year had passed, and there was no figure around, but when there were more and more sea ships coming and going here, it was the government of Annam who discovered it.

In fact, they had already sent someone to Jiaozhou to apply to the local officials, and they also brought a truckload of salt, all of which was refined salt.

As a result, the refined salt was detained, and the people were driven out!

During the reign of Song Chunxi, the Great Song Dynasty canonized Li Rixian as the king of Annam, and then renamed the Kingdom of Annam.

Later, the male heir of the Li dynasty was cut off, and his daughter succeeded to the throne and gave birth to a son, Chen Rixuan, who was then transformed into the Chen dynasty, and in addition to claiming to be the king of the Great Song Dynasty, he was called the emperor both internally and to other countries.

Now Chen Rixuan is also in the half-size period, and their country is in Jiaozhou, which is Hanoi in later generations.

One day, he received a report that an overseas Great Song Dynasty was digging for charcoal in the bay, and thousands of people had gathered. (To be continued.) )
