Global colonization began with Ming Dynasty pirates.

Lin Hao was very satisfied after completing the test.

He led Lin Chengzong directly to the intact cannons, admiring the cannons that belonged to the Four Seas Gang.

As Lin Hao approached, the gunners immediately knelt down and thanked him.

These men were prisoners of war from the previous campaign, originally responsible for firing the cannons. Lin Hao selected more than ten of them who were willing to work for the Four Seas Gang to conduct this test firing. As prisoners, they never expected to receive a reward, so when Lin Hao arrived, they all knelt down to show their obedience. At the same time, they were also worried that this pirate might turn his back on them.

"Get up, all of you. Since you are working for my Four Seas Gang, you are now one of us. You don't need to do any more hard labor." Lin Hao waved his hand, and then someone stepped forward to hand out silver to the gunners one by one.

"Thank you for the generous gift, Young Master!" the group said again.

"Thirteen!"

"Young Master, I'm here," Lin Shisan stepped forward and bowed.

"These people are now under your command. Set up an artillery research group, and the cannons will be yours for the time being. Conduct as many tests as possible and create an artillery firing training manual. Use this manual for artillery training in the future," Lin Hao instructed the other party.

In the Ming Dynasty, gunners rely entirely on intuition when firing cannons, while the West has integrated a whole set of scientific surveying methods. Although Lin Hao knows the mathematical principles of ballistics, it's all theoretical; he has no idea how to actually do it. He can only leave it to Lin Shisan to figure out.

At this moment, Lin Hao suddenly hoped that his second uncle could find him more skilled men in Macau who could perform sexual acts, so that he could simply copy their methods.

There's no faster way to do research and development than simply copying others.

"Yes, sir." Lin Shisan immediately accepted the order.

"Brother Chunlin, there's something I need to trouble you with." Lin Hao then turned to another person, who was Fu Bo's adopted son, who had previously been assigned to be the steward of the workshop. Fu Bo himself remained the Lin family's steward.

"Young Master, I'm here. Please give your orders." Peng Chunlin was a shy man, not good with words, and like Uncle Fu, he always worked quietly in the Lin family.

"Here are two sets of blueprints. Have your craftsmen make them accordingly, and then test them on these cannons." Lin Hao took out two sheets of paper from his pocket and handed them to Peng Chunlin.

Peng Chunlin carefully reached out and took it, then examined it closely before saying, "Young Master, this seems to be an artillery vehicle?"

Peng Chunlin was a little unsure. The two drawings were very different in style. If it weren't for the fact that they both had the same places for placing the cannon barrel and fixing the cannon ears, he wouldn't have thought they were the same thing.

"That's right, this is a gun carriage." Lin Hao nodded and then explained to the other party.

"The one with the larger wheels is the gun carriage in front, which carries the cannon, and the general-purpose ammunition carriage in the back. The combination of the two allows it to easily pull the cannon. As for the one with smaller wheels, it was designed for the use of the cannon on a ship."

The design Lin Hao presented was the most common single-tailed gun carriage design in later generations, and also the design most commonly used by Napoleon cannons.

When it comes to artillery, you can blindly trust Napoleon.

This type of gun carriage can easily tow away the cannon and is highly adaptable to terrain. In addition, the elevation angle of the cannon during firing is no longer modified by wooden wedges as is the case now, but is achieved by rotating bolts behind the breech.

The height adjustment is easy and quantitative, which can greatly improve the speed and accuracy of shooting.

The other was a small-wheeled gun carriage, which was common in the age of galleons. Its main purpose was not transportation, but to dissipate the recoil by moving backward after firing.

This not only reduces the pressure on the ship's hull when the cannons fire, but also makes it easier to reload.

In comparison, the Ming Dynasty's current method of fixing cannons directly to ships is incredibly stupid.

With the addition of gun carriages, the caliber of cannons that the ship can withstand can be increased further.

"Young Master, the structure isn't difficult. I'll arrange for people to make a trial run right away. How many do you need?" Peng Chunlin replied.

"Build one of each first, then test it on Thirteen, and adjust and optimize it based on Thirteen's usage. Mass production will only begin after it's fully finalized." Although Lin Hao's drawing was very comprehensive, it still needed to be modified based on actual user feedback; it couldn't be copied exactly.

"My son has made thorough preparations, even the artillery vehicles are ready," Lin Chengzong said with a smile.

"Father, I hope you don't think I'm meddling too much. After all, you're in charge of the workshop," Lin Hao said with a wry smile.

"Ah, you're mistaken." Lin Chengzong stroked his small mustache with a smug look on his face and said, "I'm overjoyed to have such a capable son, how could I possibly complain? My son knows a lot, so I, as his father, can finally enjoy my retirement. All of this is new to me, and if I were to arrange it, it would probably turn into a complete mess."

"Ahem, I've just read a little more books, which is enough to point these people in the right direction, but I'm not good at doing the actual work. My father will still need to supervise and manage it personally." Lin Hao resisted the urge to roll his eyes. This old man was trying to slack off again.

"It's alright, there's not much to do right now, you can take care of things first." Lin Chengzong looked around and saw that Lin Hao had finished looking, then continued to ask, "Hao'er, now that the cannons have been test-fired, let's go back."

"Father, what time is it?" Lin Hao shook his head helplessly. He then instructed Li Qiang, "Make another 30 cannons of the same specifications. Also, can you make a larger cannon for Li Neng?"

"May I ask what size you require, young master? The largest cannon I've ever made is a thousand catties, but I don't know what size to use for anything larger," Lin Neng said, forcing himself to speak.

"What is the barrel-to-caliber ratio of a 1000-pound cannon that fires multiple projectiles? That is, the ratio of the muzzle width to the length of the cannon," Lin Hao pressed.

"Well, I only know the general idea of ​​this little guy. He weighs about a thousand catties and is about six feet long. The muzzle is about three and a half inches long. I don't know about the bullets he uses, but they should be around ten catties," Li Neng said cautiously.

Lin Hao did a quick mental calculation: six feet is about 2 meters, the caliber is about 11 centimeters, and the caliber multiple is about 18, which is roughly the same as the batch currently being manufactured. It is not considered a long cannon.

The 11-centimeter caliber, when compared to the current 7-8 centimeter caliber, is roughly equivalent to a 12-pounder cannon.

"Make all the cannons you've made before, and make one 1000-pound cannon. Also, make a longer 1000-pound cannon, keeping the same caliber but increasing the length to 7 feet."

A 7-foot cannon, or 21 times the barrel length, is considered a standard long cannon. Within a certain range, the longer the cannon barrel, the greater the range.

Lin Hao planned to place several long cannons on Dongluozhai and the hills on both sides, so that if the government troops attacked again like last time, they wouldn't even be able to enter the bay.

Lin Hao then gave some instructions on cannon casting before heading to the next location, surrounded by the crowd.
