Historical records record that Xu Guangqi was a Catholic, and Yang Bo saw that Xu Erjue also made a cross on his chest, and guessed in his heart that the descendants of the Xu family were probably baptized and converted to Catholicism.

This made Yang Bo sigh in his heart, religion is such a thing, confusing people's hearts, the most effective, ancient and modern, Chinese and foreign, no exception.

In the afternoon, everyone came to the Nanxi River bank fort, Han Zanzhou, Zuo Wencan, and a few Dutchmen, Wan Baine, Saunders Hogan, and Billy Lange, had been waiting for a long time.

When Xu Ji saw that the three Dutch prisoners of war were also there, he immediately thought of the task given to him by his father in the letter, so he proposed to Yang Bo that he wanted to meet them, and the reason turned out to be that these Dutchmen were also Catholics, and as Catholics, they should go to visit them now.

Yang Bo didn't stop him, he just pouted, thinking in his heart, if Xu Guangqi had seen what the European whites had done to the Indians in the Americas, he would have regretted converting to Catholicism.

At this time, the Anglo-Saxons of Great Britain were grabbing territory on the American continent, and the missionaries were pretending with Bibles in their hands, while the soldiers were killing with muskets in their hands.

Those who follow me prosper, and those who oppose me perish.

Tens of millions of Indians died at the hands of the whiteskins, and the race was nearly extinct.

The law of the forest is the essence of this world, and religion is often just a beautiful cloak on the colonizers.

However, in the Ming generation, those Western missionaries at least seemed to be sincere missionaries, but in the eyes of Yang Bo, who came in later generations, it was just these people who thought that the time had not yet come to use guns.

Since their time has not come, let it never come.

Xu Ji wanted to talk to the Dutchman Xu Yi about friendship with the church, but it was wishful thinking.

He and the Dutch first did not understand the language, he knew a little Italian, but the Dutch could not, and finally Wan Bain translated the Dutch into English, and Yang Bo translated English into Chinese and spoke to Xu Ji.

The Dutch had no interest in Xu Ji, a Catholic, and a look of impatience quickly appeared on his face.

In contrast, Wan Baine was more willing to talk to Yang Bo.

"Mistyang, I congratulate you, congratulations on your successful sneak attack on the Black Rock Cliff again."

Wan Baine: This is sarcastic, Yang Bo will only engage in sneak attacks.

Yang Bo glanced at Wan Baine, but he was in the sun, and said: "That day, I wanted to fight with you head-on, but there was only Liu Xiang on the sea, until Liu Xiang was defeated, and I didn't see the Dutch come out to show their faces, but why?" ”

"You Chinese talk about the way of a gentleman when you open your mouth, in my opinion, you succeeded twice, using sneak attacks, no matter what, it is difficult to say that it is a gentleman's doing, right?" Wan Baine argued.

"Huh.." Yang Bo's tone was light, as if he was talking to himself, "You let me talk to a group of robbers about how to be a gentleman?" ”

"You.." Wan Baine suddenly froze.

Yang Bo no longer paid attention to Wan Baine, but climbed straight to the highest point of the fort, the wind was strong at the height, blowing on his body, seamless, and like a sharp blade, piercing to the bones.

The shooting range is at the mouth of the Nanxi River, the river here is very open, and the distance between the south bank and the fort, Yang Bo has made accurate measurements, less than three miles.

This distance should be the limit distance for the Dutch cannon to carry out effective shelling, although the cannon run can hit twice this distance at most, but more than three miles, it completely loses its target, and engages people at sea, such shelling is meaningless.

The river formed a thick ice ballast on the bank, but the surface of the river did not freeze.

Lei Zhizi's men were dragging two target boats over, and they had to smash the ice on the shore for a long time before they put the target boats on the river and ran aground, so as to prevent the target ships sunk by artillery from blocking the channel.

On the turret, two guns were placed side by side, one was the latest artillery developed by Shimiao, and the other was a Dutch cannon removed from the Burisem.

Wang Changsheng and his artillery squad were adjusting the angle of the gun barrel, calibrating the ruler, and making final preparations for the shelling.

A group of people, Han Zanzhou, Zuo Wencan, Xu Ji and his son, gathered in a heap, pointing, a few Dutch prisoners of war, around the two cannons, and they were also chattering non-stop.

"It's a donkey, it's a horse, pull it out and slip it."

Yang Bo walked down from the height, but the corners of his mouth were hooked with a smile.

Billy Lange was particularly interested in Yang Bo's artillery, and surrounded it, turning around and around, and finally stopped at the muzzle of the cannon, and knocked it vigorously with his hand, and the barrel of the cannon range sounded, Billy Lange muttered in Dutch, probably not a good word, Yang Bo glanced at Wan Baine, and Wan Baine asked: "This cannon is not a bronze cannon?" ”

"Hmm.." Yang Bo nodded and said, "This cannon is iron, and iron artillery is cheap." ”

"Hah.." Billy Lange sneered, "Mr. Young, you don't want us to die with you. With that, he jumped back exaggeratedly, as if trying to dodge the explosion.

The three Dutchmen laughed together.

"Yang Bo, why is your artillery so dark?" Han Zanzhou was a eunuch and a layman to artillery, and when he saw that Yang Bo's cannon was dark and looked a little weird, he couldn't help but ask.

When Yang Bo heard this, his heart moved, and he smiled: "This is a black tiger cannon, which is naturally black." ”

"Black Tiger Cannon? Black Tiger Digging Heart? Han Zanzhou was stunned, and soon said happily: "This name is good, it sounds mighty." ”

Others don't see it that way, and if you want to talk about might, the Dutchman's cannon run is really mighty.

The tall and black body is stupid, and the copper cannon body shines with a faint cold light, which is daunting.

In contrast, Yang Bo's new cannon is less than half the weight of the Dutch cannon, the body is one size smaller, the barrel is slender and slender, and it looks weak.

The gun body is dark, that is because Yang Bo has a blackening process, that is, a layer of aqua regia is brushed on the gun body, and the iron surface is oxidized by strong acid to form a protective layer of trioxide tetroxide, which is hard and dense and can prevent rust.

This is a technological process that is ahead of the times, and Yang Bo will certainly not reveal it easily.

Iron is rigid and brittle, while copper has much better ductility, and under high temperature conditions, the barrel of the same thickness is more likely to explode, not to mention that Yang Bo's iron barrel is very thin.

For artillery, Xu Ji is half an expert, thanks to his father, Xu Guangqi has always valued ordnance, and Xu Ji also knows something.

Iron artillery is not without in the Ming army, for example, most of the tiger squat cannons are iron, but the charge is small, and the power can not be compared with the canon run of the Dutch, iron tiger squat cannons, the outside of the barrel is usually hoop a few thick protective iron bars, one is to prevent the explosion of the bore, and the other is that even if the bore is blown up, there are protective iron bars, and it will not cause fatal damage to the gunner.

Xu Ji guessed that Yang Bo must have wanted to compete with the Dutch artillery when he pulled the Dutch over today.

But these two cannons are put together, just like a thin and withered little man and a big man with horizontal flesh standing together, the black tiger cannon, no matter how you look at it, I don't think it's enough to see.

Wang Changsheng had already begun to load the ammunition, but the Dutch was stunned, the projectile of the Black Tiger Cannon was not a round solid iron ball, but a cylindrical one, and there was an oval tip in front of it, and it was impossible to figure out what medicine was in Yang Bo's gourd for a while.

Yang Bo replaced the solid iron ball with a cylindrical projectile, which was filled with nitrocellulose explosives, which weighed much lighter than the solid iron ball, the projectile was light, and the range could be longer.

"It's all out of the way, it's fired." Wang Changsheng waved the small flag in his hand and shouted from above.

The target boat on the other side of the river had been towed into place, and a soldier came over and signaled everyone to retreat to safety.

However, the first shot of the Black Tiger Cannon was not loaded with a projectile, and the gun charge was only one-third of the normal amount.

"Boom..."

The small flag in Wang Changsheng's hand waved down, and the black tiger cannon opened fire in response, but there was no projectile, only an empty cannon.

This shot drew a burst of laughter from the Dutch.

"Yang Bo, what are you playing with?" Han Zanzhou asked anxiously.

Xu Ji also looked at Yang Bo, with a worried expression between his eyebrows.

"It's too cold, it's a warm cannon." Yang Bo said casually, but his tone was light and light.

This cannon is also called a test gun, and the purpose is to raise the temperature of the barrel before the official opening of the gun.

Yang Bo was a military fan in his previous life, and often wandered in various military forums, no matter how advanced the artillery is, it is also necessary to preheat the barrel, which is one of the means to prevent the explosion of the bore.

When the Black Tiger Cannon was being tested, Yang Bo remembered this trick and used it when he took it, and after the test, the effect was good, so it was written into the artillery drill code as a standard step and fixed.

"Boom, boom.."

The artillery was fired again, this time, both guns fired at the same time, the Black Tiger cannon on the left, and Ganon ran on the right, but unfortunately both guns did not hit the target, and the shells fell into the river, splashing two water columns, one high and one low.

"Boom, boom.."

In the third round, the Black Tiger Cannon hit the target first, and the target ship on the left was hit, and after a loud bang, the hull was torn apart, and a fire broke out, and it was about to disintegrate.

Ganon ran to the fourth round, and finally hit the side of the target ship, the side of the ship was cut off a large part, and a huge gap appeared, compared to the left, in terms of the degree of damage suffered by the target ship, it was obvious that the results of the Black Tiger Cannon were more significant.

"It's not fair." Wan Baine shouted, "Who knows if you have pre-planted gunpowder on the target ship?" ”

Yang Bo didn't pay attention to it, but shouted at Wang Changsheng: "Fight again, fight at the riverbank." ”

"Boom..."

This time, the projectile landed on the gentle slope on the other side of the river, and in an instant, a violent explosion occurred at the point of impact, ice, snow, and mud splashed everywhere, and a huge crater appeared on the river bank.

Wanbaine stared at the crater with wide eyes, his expression glazed over, and he was silent for a long time, and Saunders and Billy Lange also looked stupid.

"Hahaha."

Yang Bo looked up to the sky and laughed, and the shelling drill was over.

The crowd of onlookers left one after another, each with different thoughts.

"Brother Xiangwen, please stay." Yang Bo stopped Han Zanzhou, walked over, and whispered mysteriously: "I have a big gift to give to Brother Xiangwen, can Brother Xiangwen be interested in listening to it?" ”

"Yang Bo, if you have something to say, don't mess around with our family there."

"Our little heart is still trembling." Han Zanzhou glared and stomped his feet, and when he saw that Yang Bo was unmoved, he said tentatively: "Something to do with the Dutch? ”

"Brother Xiangwen knows everything, and I will give it to Brother Xiangwen as a Dutch prisoner of war."

"Is this your gift? What do we want these Dutch red hairs for? Han Zanzhou suddenly blurted out with a look of resentment, but he was quickly stunned and asked tentatively, "You mean... Take these red-haired ghosts to exchange silver for the emperor? ”

Yang Bo glanced at Han Zanzhou with a look of disdain.

"The Dutch still occupy the Great Yuan, the Great Yuan has been since ancient times, but in the land of China, Brother Xiangwen never thought of opening up the territory for my Ming Dynasty?"

The Da Yuan in Yang Bo's mouth is the Taiwan of later generations, and 'Da Yuan' is very similar to Taiwan according to the reading of Hokkien dialect.

Han Zan Zhouqi said: "Exchange prisoners of war for Dayuan? Yang Bo, do you think the Dutch will agree? ”

Yang Bo shook his head and sighed, and said in distress: "Dare to love my Black Tiger Cannon for a long time, and all of them are busy in vain?" "Black Tiger Cannon?" Han Zanzhou shook his head, raised his hand and raised his orchid finger, pointed at Yang Bo, and exclaimed, "Yang Bo, you want to use this."

"Hmm.." Yang Bo finally nodded and said, "What do you think of my big gift, Brother Xiangwen?" ”
