A bronze cannon, three masonry workshops, a rusty iron scale, and a messy bag of gunpowder materials made up Deng Haonan's first workplace after his reincarnation.

Deng Haonan circled around the bronze cannon on the ground a few times, and took a felt to clean it thoroughly.

Next to him was Yan Siyu, staring at Deng Haonan angrily. Looking at her posture, if Deng Haonan can't give her a satisfactory answer, he may turn his face and take revenge on himself.

Deng Haonan said in his heart: This ancient lady looks like she has a lot of temper, and now she can't fight her, so don't talk back to her again!

After Deng Haonan's judgment, the artillery in front of him should be equipped with a "tiger squat cannon" in the Ming Dynasty Army. The head and tail of this cannon are 2 feet long, and the head of the cannon is erected by two iron claws, and the shape resembles a crouching tiger, which looks very majestic. However, a tiger scratches and breaks. Deng Haonan had to order someone to cut off his other paw and replace it with a pair of hardwood shelves.

According to Deng Haonan's estimates, the bearing capacity of the barrel of this artillery is not bad, about one kilogram of ** explosive yield. Before firing theoretically, first load hundreds of lead bullets or stones weighing 5 yuan, and then press the top with a large lead bullet or large stone bullet weighing 30 taels, and when firing, the large and small bullets fly out together, and the lethality within one mile is still very amazing.

The light weight and small size of this cannon made it very suitable for cavalry to carry directly with war horses, which gave birth to the cavalry artillery of the Ming Dynasty Army. Deng Haonan thought that this should be the main equipment of the artillery when Qi Jiguang resisted the Japanese. It was also the first cavalry artillery in the history of mankind, about 200 years ahead of the West.

Compared with today's artillery, the bronze cannon of the Ming Dynasty is very far behind, and Deng Haonan's cognition of this kind of artillery is limited to books.

This tiger squat cannon weighs about 40 pounds as a whole, and although its appearance is a little older, it has become more beautiful under Deng Haonan's washing.

Yan Siyu and several gunpowder field workers stood aside, ready to give Deng Haonan a hand. The workers are stealing from the master in disguise, after all, the work of the gunpowder master at this time is very fashionable and popular for the pirates! But Yan Siyu watched Deng Haonan concentrate on his work and wandered every time, not knowing what he was thinking! However, at this time, her cheeks were still red, and it seemed that the aftermath of watching Deng Haonan's striptease just now was still there!

After cleaning up the tiger squat cannon and making sure that it could still take on the shooting mission, Deng Haonan began to sort out the artillery propellant.

There were a lot of gunpowder materials piled up in the room, which made Deng Haonan embarrassed. Xindao: These people are really idiots, so many gunpowder materials are piled up like this, if one is not careful, encountering an open flame, there is not a single scum left.

The simplest black powder is nothing more than one sulfur, two nitrates and three charcoal, which will be matched with middle school students in later generations, Deng Haonan naturally thinks that it is pediatrics. Immediately ordered someone to take the three materials, and then Deng Haonan divided five by two, and wrapped the first package of propellant.

After loading the propellant into the tiger squat cannon, Deng Haonan then loaded some gravel in turn, because there was no 30 taels of lead bullets, Deng Haonan had to replace it with an iron ball of about 25 taels. I checked the tightness, and it was reasonable.

It's just an experiment, Yan Siyu doesn't have high requirements for Deng Haonan, as long as he can let this gun fire. However, Deng Haonan was an expert in naval artillery in his previous life, and once he started working, his meticulous appearance made Yan Siyu's evaluation of him a little higher in his heart.

Sure enough, it's a talent! Although Deng Haonan's first shot has not yet been fired, in Yan Siyu's heart, after seeing Deng Haonan's professional way of working, the doubts about him in her heart have disappeared, and she is glad that she was lucky to meet him.

At this time, Deng Haonan revised the light door of the tiger squat cannon again and made a simple three-point-one-line aiming device.

"That's it! Succeed with flying colors! It's time to test the gun! Deng Haonan clapped his hands and glanced at Yan Siyu demonstratively.

Yan Siyu was also looking forward to it in her heart, and immediately nodded at Deng Haonan with a smile, and at the same time covered her ears with both hands.

Although he couldn't see the expectation behind her veil, judging from the fact that she was willing to hire him at a high price, Deng Haonan could feel her mood.

Deng Haonan picked up the torch, lit the fuse, the fire rope burned out, and there was a muffled sound, but he saw that the tiger squatting cannon spit out thick black smoke, and the cannonball cut out the barrel of the cannon, rubbing out dazzling sparks, and then the cannonball and gravel fell three hundred meters away.

"It worked!" Several nearby gunpowder field workers cheered loudly and were overjoyed. Since the ransacking of the town of Beimao three years ago, more than half of the gunpowder workers have been killed, and the rest have been captured by other pirates. Since then, there has been no more gunpowder available in Bei Tan. Li Ping spent a lot of money to rebuild the gunpowder field, but all the forces controlled the gunpowder workers extremely strictly, and Li Ping only got back a few workers who knew nothing. At best, these workers know what to use for the powder field, but they don't know how to put it together. As a result, there are now mountains of gunpowder materials in the house, but none of them are ready.

For them, being able to explode gunpowder and fire cannonballs is already the greatest luxury.

Similarly, although Yan Siyu had seen more powerful artillery than this, his brother's Twenty-Eight Brothers Alliance had actually been overturned by Zheng Yiguan and others, and key workshops such as gunpowder fields, shipyards, and ironworks were all controlled by them. Yan Siyu couldn't get the information and technology in it at all, so he would collect talents everywhere, and he had very big expectations for Deng Haonan.

"Congratulations!" Yan Siyu walked up to Deng Haonan and said, "You were able to dispense gunpowder in half an hour, and the test was successful, I really didn't misunderstand you!" ”

Then Yan Siyu saw Deng Haonan's unhappy look, and thought that he was still worried about his revenge on him, so he said: "The previous things are written off." If there is anything offended, I hope that Deng Gongzi Haihan! Siyu has made amends to Deng Gongzi! Then facing Deng Haonan is a blessing.

In fact, Deng Haonan didn't think about being unhappy with her, but annoyed that he had miscalculated, the original maximum range should be about two miles, and the effective range should be about one mile. And at this time, the result was only 300 meters, which really embarrassed him, a top artillery expert!

At this time, Deng Haonan saw Yan Siyu, who was still fierce just now, and his attitude changed greatly, not only calling himself a son, but also gently taking the initiative to apologize to himself, which also made Deng Haonan's heart happy, and the previous grievances were also a little lighter, after all, are they girls? Good men don't fight with women, as Deng Haonan, who thinks he is the best man in the Ming Dynasty, he still has to be generous at this time, isn't it?

Deng Haonan smiled slightly, and said very gentlemanly: "Miss Yan is too worried!" I was just a little disappointed because of the miscalculation just now, and the shell was supposed to hit two miles, but it turned out to be only three hundred meters away! ”

Yan Siyu didn't know how far three hundred meters was, but he knew what it meant for the cannonball to hit a distance of two miles! At the moment, he said in surprise: "Deng Gongzi means that this forty-pound tiger squat cannon can hit a distance of two miles?" Although Siyu hadn't heard of it, he had seen the thousand-pound cannon on the Dutch battleship, which was several times larger than this, and it could only hit two or three miles away! ”

Deng Haonan just smiled faintly, his eyes were full of disdain, and he was confident in himself. said: "Miss Yan, there is still half an hour before the time you specified!" Why don't you try the cannon again in the next one, and let the young lady see how effective this tiger squat cannon is for two miles? ”

In Yan Siyu's surprise, Deng Haonan had already turned around in a dashing manner and re-devoted himself to the test work.

Looking at Deng Haonan's back, Yan Siyu was stunned. Just now, he was still a hooligan, but at this time, he was judged to be like two people, and he suddenly became polite and polite, like an aristocratic temperament!

"What kind of person are you? Why can't people see through you? Yan Siyu muttered, and her thoughts couldn't help but recall every picture since the two met. Compared with the respectful title of Miss Yan, Yan Siyu hoped that Deng Haonan would call her Death Sanba, a crazy woman, although she didn't know what it meant to die Sanba, but she had a strange happiness at that time.

O woman! Always curious about the unknown!

Here, Deng Haonan had already ordered someone to re-obtain the various ingredients of gunpowder and began to check them one by one. These workers seemed to respect Deng Haonan like a god at this time, compared to their previous disdainful attitude, it was simply a world of difference. One by one, they stood not far from Deng Haonan in a respectful manner, watching quietly, and at the same time executing every word of Deng Haonan cleanly, usually they served the master and did not serve the master so quickly!

After gently tasting the taste of various raw materials with his fingers, Deng Haonan suddenly realized that he had forgotten the most basic truth. One sulfur, two nitrate and three charcoal are indeed the correct configuration of black powder, and the power is also quite large, instantly producing a high temperature of 1,000 degrees, and the destructive power is extremely strong. At this time, the saltpeter has a slight alkaline smell, and it is obvious that the workers are just painting gourds to purify it, and the content of ** is not high. The sulfur is okay and has a high purity, but it has a little more butter, which obviously affects the combustion value. Although charcoal is possible, there is too much bark residue in it, and it is obvious that the workers did not peel the wood, which will cause a large amount of smoke after the gunpowder burns, reducing the power of the gunpowder.

It's just that Deng Haonan ignored the most critical factor, that is, this configuration is a theoretical configuration, even under the developed storage technology in later generations, it is impossible to truly achieve the maximum explosive power under this configuration, not to mention the ancient times when the storage technology is extremely backward?

Deng Haonan tasted the ingredients one by one, and he could not reach the purity of black powder in later generations, so it was naturally impossible to achieve the ideal effect according to the combination of one sulfur, two nitrate and three charcoal.

At this time, if Deng Haonan wants to deposit these materials, it is obviously not enough for half an hour. immediately came up with a solution, so after ordering someone to take a large number of materials, Deng Haonan arranged and combined these materials according to the proportion, prepared about thirty groups, lit them one by one, and then observed the burning situation by himself.

It happened that the fifteenth combination had a high combustion value and took a short time, so Deng Haonan immediately prepared a new propellant according to its configuration, weighing about two kilograms. Deng Haonan did not increase the weight of gunpowder for no reason, because if there is too much gunpowder, it may explode. At this time, Deng Haonan found that the tiger squat cannon was not cast, but artificially polished. The craftsmen of the Ming Dynasty originally made artillery by manual polishing, not casting in batches, so the strength of artillery-polished artillery was about ten times higher than the strength of cast artillery, so Deng Haonan dared to increase the amount of gunpowder.

After cleaning the chamber of the Tiger Squat Cannon, Deng Haonan further crushed the gunpowder, mixed it thoroughly and loaded it into the chamber, and then gently put the shell inside. At this time, Deng Haonan didn't dare to be arrogant anymore, because after the system check just now, he knew that he was too careless for the first time. Because charcoal contains a large amount of powder after burning the bark, gunpowder is the most likely to explode. So this time, Deng Haonan carefully sealed the gunpowder and shells.

After adjusting the door and inserting the fire rope, Deng Haonan signaled to Yan Siyu and everyone that he was going to open fire.

Yan Siyu smiled and nodded, covered her ears again, Deng Haonan smiled back to her, and then picked up the torch and lit the fuse again.

Sneer-thump!

There was a loud bang, and I saw the tiger squat cannon roaring, and the cannonballs flew out of the barrel of the cannon at once, hitting the distance. The crowd shook violently, and several workers were immediately frightened. Compared with the test gun just now, this time the power is several times greater.

After the sound of the cannonball, Yan Siyu quickly ran to the point where the cannonball hit, and then walked towards the tiger squat cannon again.

A moment later, Yan Siyu walked to the muzzle of the cannon and immediately shouted with joy. More than 1,900 steps, about two miles up and down.

When everyone heard this, they immediately cast an extremely admiring look at Deng Haonan, Deng Haonan just smiled faintly, stretched out his right hand into the air and snapped his fingers, and said, "Little meaning!" ”
