Song Youliang looked at Donat and said, "I don't remember asking you to bring a priest~"

"They are here on their own, and I am only responsible for bringing them to the East!" Donat shrugged his shoulders

"The Lord will give you strength and wisdom!" Father Bergin is also fluent in Chinese

Donat laughed, "But I think you'll like them, because these two priests are well-versed in ballistics, mechanics, and chemistry. You should really like what they bring~~" Donat pointed to something that several sailors were struggling to move down, "Whoa~ That's the machine tool that makes the barrel of the musket. ”

"Oh?" As soon as he heard that there was such a good thing, Song Youliang's eyes immediately lit up

The corners of Father Thomas's mouth curled slightly, and a sly smile appeared, and then in a flash, he said in a tone of great reverence: "God will only give power to Christians who believe in him." ”

"I am willing to be baptized and permit you to preach and establish churches within my jurisdiction. But you must impart to me your knowledge, and these machines. Song Youliang has long known what these Jesuit priests are doing, Xu Guangqi and Sun Yuanhua are both baptized Christians, and it doesn't hurt to join Catholicism himself.

The arrival of these European craftsmen added new techniques to Haiyangwei, and there were also professional architects among the craftsmen, which made the architectural style of Haiyang Acropolis a combination of Chinese and Western, such as in the design of the enemy tower, the shooting hole had the original single round hole turned into a T-shape. In this way, both crossbowmen and musketeers can shoot at different angles.

In terms of musket manufacturing, the traditional barrel manufacturing technology in China is mainly based on two methods: three-stage joint type and double-layer composite type. The method of three-stage joint type is: the first step is to make the pipe. Prepare a steel core of a cylinder about 30 centimeters long and about 7 millimeters in diameter to make cold bones, first burn the wrought iron to make the pipe until it is red-hot, and then the craftsman takes out the blank that has been burned to a certain temperature, knocks the hot wrought iron outside the steel core with a hammer, and rolls it into an iron pipe. And in the process of cladding iron, the steel core is constantly extracted and cooled with water to prevent the steel core and wrought iron from being welded together. The thickness of the rolled iron pipe should also be about one centimeter. In this way, the gun tube is strong and can withstand more than a dozen consecutive launches.

The second step is welding. Because the long guns of more than three feet are welded in sections, so the guns that are not well welded are easy to be fried and bored, and the craftsmen regard whether the seamless guns are welded as the key to the success or failure of the guns. In the middle of the Ming Dynasty, the craftsmen of the Ming army took advantage of the Japanese invasion and caused many accidents. It is recorded in the "New Book of Ji Xiao": "Recently, I have learned that there are few people who are sick and suffering, and they do not complain and instruct the craftsmen to listen to them roll into iron cylinders, uneven thickness and thickness, and even single cylinders are rolled up, and they are damaged by explosions." "The above method is made of iron pipes and then burned in the furnace until incandescent, and a steel core is also prepared, the thickness is the same as above, and the length should be longer than the length of the gun. Then the iron pipe that has been burned to red and bright is sleeved on the steel core, and the iron pipe interface is vigorously smashed into one by the master craftsman, and at the same time of welding the iron pipe, the auxiliary hammer hand also sprinkles white copper powder on the welding mouth of the iron pipe, and the copper has an affinity effect, which can make the welding mouth stronger, and not to leave a fault or virtual welding. The steel core should also be extracted and cooled at any time, and the iron pipe should be heated while cooling the steel core. The final iron pipe is the prototype of the gun pipe.

The double-layer composite gun body is different from the above method, it is directly wrapped with red iron on a one-meter-long steel core, when the first layer of iron is wrapped, another layer is wrapped on this layer of the gun body, so that the joint of the inner gun is wrapped by the outer layer of the gun body to form a complex. From a technical point of view, the double-layer composite gun is more scientific than the three-stage joint gun, and the gun body joint is stronger, although this kind of gun tube can not make a very long bird gun tube, but the caliber can be made larger than the first bird gun, so the power is also greater in a limited distance.

After the barrel is made, it is time to start polishing the inner wall, the early barrel is often made into an octagonal shape, with one end of the body thick and one end thin, the thick one makes the belly, and the thin one makes the mouth. At this time, the barrel is still a rough embryo, and the craftsman has to drill out the boring again to break the crosshair. Due to the limitations of the process at that time, the steel core section is not pure round, and the core is not straight, and the boring is rough and uneven. In the Ming and Qing dynasties, there was this kind of drilling machine, which was framed with wood, and the round stone disc was used as an inertia wheel, and the leather strip was tied and pulled by manpower to make the stone disc drive the drill bit to rotate. In the Ming Dynasty, good drill bits and frustration knives and other tools made of hard steel were made of fallen steel, and the rigidity was not very hard, so half of the time to make bird guns was drilled and scraped. It can last up to a month. "Ji Xiao Xinshu" recorded: "(Bird) the original hole is very small, drill it with a steel drill, drill an inch a day, until the end, and drill light in January." "When the boring is finished, the inside of the boring is scraped clean with a four-edged steel bar, so that the pipe is made.

In addition, the European immigrants brought Song Youliang many unexpected gifts - tobacco seeds, corn, potatoes and Hessen Jeger rifles. The benefits of corn and potatoes go into detail, just tobacco and Jager rifles

The history of tobacco in China can be traced back to the Ming Dynasty, and in the third year of Wanli (1575), tobacco was introduced to Taiwan and Fujian from Luzon. In 1579, Matteo Ricci brought snuff to Guangdong, and the number of smokers in China soared. In 1637, in order to ban smoking, Chongzhen ordered to punish the smugglers by beheading.

The first ban on smoking in the world was in the 17th century, and the advocates of smoking came from several sources, one is the religious forces, who believe that smoking is the embodiment of the devil. One of Columbus' sailors named Rodrigo de Jerez learned to smoke tobacco in Cuba and continued to smoke it after returning to Spain. The Spanish inhabitants, seeing that he could smoke from his mouth and nostrils, believed that he was the devil's incarnation, and were sentenced to imprisonment by the Inquisition; the second is the medical profession, which believes that smoking steals the doctor's business (because many people think that tobacco can cure diseases); The third is the kings of various countries, who believe that smoking leads to the loss of wealth. The first country to impose a strict ban on smoking was England, where in the 17th century, the king of England sentenced a nobleman who smoked to death. Throughout the 17th century, smoking was strictly prohibited in many countries. For example, the Persian kings burned smokers to death, and some poured dissolved lead into the mouths of tobacco merchants. Turkey publicly executes all smokers, beheading, hanging, and **, and cruel methods emerge one after another; In Russia, for smoking and selling cigarettes, the first offender was whipped, the second offender was put to death, and the nose of the snuff smoker was cut off; Greece's penalties for tobacco smokers are similar to those in Russia; Smokers in Switzerland are beaten or branded; North Korea imposes prison sentences on tobacco smokers; In Japan, property is confiscated for first-time offenders, and jail for repeat offenders; In India, the nose of the trafficker is cut off.

In fact, this popular anti-smoking campaign has little to do with what we call health today, and it is more about wealth. After Columbus discovered tobacco in the Americas, Spain started a tobacco business. Portugal was the first country to successfully introduce tobacco cultivation in Europe. Since then, tobacco has been grown in France, Italy, Germany, etc. In the 17th century, these countries did little to stop smoking because tobacco had become a means of making money, and the British-led countries found that the prevalence of smoking would lead to a massive loss of wealth, so the rulers did not hesitate to use the death penalty to stop the spread of tobacco in their countries.
