Howard didn't know Yang Feng's sinister intentions, but if it was really like what Yang Feng said, he might need a large number of slaves in the future, then it was obviously not cost-effective to transport it from Africa to this side, mainly because the mortality rate was too high, after all, they were all bought from those kings and chieftains in Africa for a penny, and a slave was a few pounds, and the distance from East Africa to China was far greater than that from West Africa to the Americas, so the mortality rate on the way would definitely exceed that of the Americas, and the mortality rate of the transportation to the Americas was already very high.

In this case......

"Maybe we can try, but I don't know if the sultans are willing to sell their prisoners of war, and you know it's a matter of faith."

He said with a shrug.

"I don't care, but there is one thing, the first must be a male slave cut by Yan, and the second must not be Chinese, don't think I don't know what the Dutch are doing."

Yang Feng said.

At this time, the Dutch have been playing or hiring pirates to capture Chinese to Java as coolies, because the local natives are too bad and stupid, on the contrary, the Chinese are smart and diligent, very suitable for them to work, and many of the Chinese who died in the famous Hongxi tragedy were captured in this way, Yang Feng did not want to buy his own compatriots in the end, he wanted these colonists to help him empty Southeast Asia to the maximum, not just for a few slaves.

"Of course, we're not Dutch."

Howard said.

That's it.

In fact, at this time, China's population is more than 100 million points, and there is no need for slaves in theory, Yang Feng did this purely to harm his neighbors, anyway, he didn't need to pay much cost, it was nothing more than to let Lin Qian OEM some aluminum alloy, stainless steel, plastic utensils, zircon, some messy gadgets, pocket watches, in short, they were all worthless bits and pieces, and then he could lure these colonists to kill in Southeast Asia.

Catching slaves is very bloody, and behind a slave is a lot of blood.

As for the other problems of the two, there was nothing to say, and soon Yang Feng prepared another box of messy treasures for them, and then sent Howard and Wallace away, and on the same day that the two left, the Ming fleet set sail again under the personal leadership of their marshal, and a few days later this huge fleet appeared in the chicken coop, and then the accompanying army battalion landed to officially seize the land, and the only resistance encountered came from a clouded leopard.

As for the reaction of the local Kedagran people......

This one is not worth mentioning.

In fact, these familiar fans have long been accustomed to the nominal rulers here and there, in the past few decades, this small place has changed the Spaniards, the Dutch, the Zheng family, the Qing Dynasty four rulers, as long as it does not affect their fishing and farming, they are not interested in care, plus Lao Chen knew several tribal leaders when he was in the Zheng family, although it has been many years, but at least he can speak, and there is no obstacle after contacting.

Besides, it's useless if they don't agree.

As for the coal mine, it is simpler, and the main coal mine in Keelung is not far from the sea in Badouzi.

Originally, the first machine coal mining in China in history was the Badouzi Coal Mine, which has been mined in small quantities since the Ming Dynasty, and the Spaniards and Dutch have done it, and Yang Feng just took it over again.

"Next, your main job is to build roads, repair docks, and cultivate coke plants, the latter I will give you a full set of technical information, in short, my request is that after three months, I must load the first ship of coke, now there are not enough people, do not require you to produce too much, as long as you can produce it, it will be successful." In the future, you will be the prefect of Jilong Mansion, the three battalions will stay here as guards, and the navy will also leave you three battleships and six cruisers, and the little sailors under the Taiwan General Army are not worth mentioning, and then you can contact the old department of King Yanping in Taiwan while engaging in construction, these warships will patrol around Taiwan, and if someone wants to defect, they can be directly transported here on the ship, and then sent to Zhoushan. ”

Yang Feng said to Lao Chen while walking on the mountain road.

It is impossible for him to preside over the work here, and in the future, all the things here will be handed over to Lao Chen, anyway, he is familiar with everything here as the old department of the Zheng family.

"Okay, Dashuai, you can rest assured."

Lao Chen nodded and said.

As he spoke, Yang Feng looked at the group of natives in front of him, the latter was obviously very interested in the team of soldiers behind him with bayonets on their shoulders, wearing plate armor and steel helmets, and they were pointing there, he smiled and walked to a huge rock in front of him that weighed at least nearly a thousand catties, this big stone was blocking the road, and several Qing prisoners of war who were taken as coolies were under the custody of the Ming soldiers, trying to pry it out and push it aside.

Yang Feng walked over and waved them aside, then pushed the rock and shook it a few times, easily lifting it out.

Those natives were shocked when they saw it, obviously frightened by his terrifying power, but a scene that made them scream even more appeared immediately, and they saw Yang Feng hugging the rock that could be hugged over, just like hugging a bundle of firewood and grass. Then he roared very imposingly, and then raised it directly above his head, and looked proudly at the natives who had turned pale with fright, and threw it out at once with a long roar, and the huge rock flew out more than ten meters directly by means of the height difference, and smashed on another rock like a cannonball, and with a loud bang, the two rocks were instantly shattered.

This force is quite powerful, these natives don't understand cannons, they are full of awe of Yang Feng's style, when he finished throwing this rock and then walked in front of those natives, many people even trembled involuntarily, and they didn't dare to look up at him.

The next thing will be completely handed over to Lao Chen, Yang Feng will return to Zhoushan directly, anyway, the two places are a thousand miles apart, as long as it is not a typhoon, it is only a few days to sail by boat, and you can come back at any time if you need to. At this time, Kang Mazi no longer has the ability to compete with the Ming army at sea, and the sailors in his hands are those who defend the Bohai Sea, and those are absolutely not daring to be sent to the south, in fact, at this time, Kang Mazi's biggest headache should be how to resist the Ming army from the sea to Dagukou. Therefore, the entire East China Sea is completely under the control of the Ming army, and there is no need to worry about any danger in the communication line between the two places.

After returning to Zhoushan, Yang Feng immediately went to guide his hydraulic boring machine work.

Relying on the largest river in Zhoushan, this boring machine builds a dam to raise the water level, uses the impact of the water flow to drive the wooden water wheel to provide power, and then turns into a high-speed rotating force through the gear set to drive the boring tool to do the simplest inner wall boring. Now the most important work is being done, all the guns currently used by the Ming army are re-boring the breech, this kind of casting cannon inner wall will always have some errors, even not regular enough, and not smooth enough, but the boring machine can solve these original defects.

Don't underestimate these flaws.

Everything else remains the same, and if these minor flaws are solved, the range of the artillery can be greatly improved.

"Four miles, the nine-pound cannon that I just tried, one shot hit four miles."

Shao Tingcai said excitedly.

The nine-pound cannon he said is a twelve-pound cannon, and Yang Feng is used to it, now the Ming army is based on the weight of the cannonball as the model, the nine-pound cannon is the largest number of artillery in the Ming army, and the previous maximum range is more than three miles, that is to say, the range of these old-fashioned artillery has increased by one-third after boring through the barrel, and now it is at the same level as the newly cast army field artillery. Of course, this is the maximum range, and if you want to penetrate the planks of the opponent's warship at sea, you still have to get a few hundred meters closer, but it is very useful to use flowering shells against infantry.

"What is this, I still have a good thing that I haven't played, and if I get this kind of good thing out, I can play ten miles."

Yang Feng said casually.

The caliber of the nine-catty gun is actually 120, such a large caliber, the firing range is on the same level as that of modern large-caliber machine guns, and it is indeed very speechless.

"What's that?"

Shao Tingcai said very eagerly that the current orthodox head of Xinxue is obviously interested in technology, in fact, not only him, but also Huang Baijia and Yan Hongkui are also interested in technology, which is obviously completely different from those masters of science, after all, this is also a character like Xu Guangqi.

"We use rifled guns, so why not use rifled guns?"

"But the copper cannon rifle is easy to grind!"

"Then cast a cannon with steel."

"But now our steel casting cannon is not better than copper, I tried it with those craftsmen, I don't know why, after casting, the steel doesn't seem to be as good as before, and then a master said that it might be a cooling problem, and I haven't figured out what is going on."

Uh, then you need the inner mold to be water-cooled.

Yang Feng thought to himself, he didn't expect his subordinates to progress very quickly.

However, this problem is easy to solve.

"Then make a steel-bore copper cannon."

He laughs.

"The inner steel chamber is rifled, and the outer bronze bears the power of gunpowder?"

Shao Tingcai's eyes lit up and said.

"yes, I guess it's not very new, is it?"

Yang Feng said.

"Yes, it's just that it used to be a wrought iron-bore copper cannon, and there is no rifling, in fact, it is not stronger than a pure copper cannon, that is, slightly lighter, it is indeed no problem to replace it with a steel bore at our level, but in this way the cannonball can't use a round one, the round cannonball is the same with or without rifling, the cannonball has to be changed to a bullet-like tip, but if it is changed to a pointed head, the weight of the cannonball must be increased, and if you want to achieve the range, you have to increase the ******, and if you ****** increase, the thickness of the bore must also increase, so is the cannon too heavy?"

"Why do you have to make a nine-pound cannon? Can't you make a four-and-a-half-pound cannon first? ”

Yang Feng looked at him speechlessly.

"That's right, we can build four and a half catties of cannon first, so that even if it sinks again, it won't exceed two thousand catties."

Shao Tingcai patted his head and said as if he had come to an enlightenment.

This Confucian is different.

Yang Feng looked at his cheerful back with some emotion.
