The density of limestone is generally 2.93 g/cm3, and the volume of a limestone ball with a diameter of 12 cm is about 900 cm3, so the stone ball they are now testing is about 2.6 kg. Pen, fun, pavilion www. biquge。 info

If a 2.6 kg stone ball flies at a speed of fifty meters per second, then the striking force it produces is one-half of the mass multiplied by the square of the velocity!

Then this striking power is considerable, and it can even be used on bronze artillery.

For them, lead is still a valuable commodity that cannot be easily wasted, unless an adversary comes in a large sea vessel.

Wanshida had people push the standard Acacia wood cannon to the bank of the Badao River and fix it.

Then Wanshida adjusted the landing gear, and he adjusted the muzzle of the gun to forty-five degrees, roughly to see how far the maximum distance could go...... After all, you can't rely on calculations on paper.

He first asked people to put in the red silk medicine pack, this medicine is a fixed amount, he doesn't want future gunners to add black fire/medicine by feeling......

After compacting with the cannon shaft, and then pushing the stone ball wrapped in deerskin hard, after feeling the same, he used a long iron awl, through the cannon hole, to pierce an eye on the red silk bag, plugged the fuse, of course, if this type of artillery is safe enough, then you can use the long red iron awl to directly ignite the medicine bag!

After lighting the fuse, he led the gunner to retreat twenty meters away...... and with a "bang", the wooden cannon jumped, and a stone bullet flew out, although it was visible to the naked eye, it still fell quickly to the left bank of the Badao River, where it stirred up a piece of sand!

Oh, the onlookers were happy, I really didn't think this could be too!

It's a good weapon!

Ignoring their excitement, Wanshida immediately carefully checked the position of the tail that served as the powder room.

He saw that the position of the cannon hole was a little burned, and next time he hit an iron mouth? Let's take a look at the final limit test......

The surface of the wood on the entire tail did not change, there were no cracks, and then he reached out and touched the chamber of the gun, which was a little hot, but there was no deformation in it......

When he tested the second shot, he lowered the muzzle to see how effective it would be when fired flat.

He asked the gunner to remove the debris from the barrel, which smelled of burning skin.

After clearing it, he had the stone bullets loaded again.

This time, the stone projectile hit the center of the river directly, causing a long splash!

Wan Shida thought, well, this thing may not be effective against a half-meter to one-meter-thick sea ship, but against a small boat or a person on a sea boat, if it hits, it will also be a heavy casualty.

When it comes to casualties, it has to be shotguns!

In the third stone shell, he slightly adjusted the angle of the muzzle of the cannon, and asked people to install the iron bowl holder that had been cast earlier, and it was filled with pebbles of similar size, which had been simply picked......

As soon as the cannon hit, the center of the river stirred up countless waves.

Wan Shida nodded, good, don't look at the group of stones in the air is slow, but as long as it hits the body, it will either be dead or injured!

The following is the limit test, he has been ordering to insert the fuse, which he made by hand, and there will never be a rapid ignition.

The final result was that after twenty shots, the tail that had been used as a powder chamber could not withstand the explosion of gunpowder, and finally after the twentieth shot, it cracked, and the wood stubble flew everywhere, but fortunately no one was injured.

Wanshida said to Captain Bowie, "What do you see? ”

Captain Bao Wei's face was flushed at this time, and he said, "Ten Thousand Lords, if there was already this...... Even if thousands of people come, we are not afraid! ”

Wan Shida said: "Silly boy, the progress of materials is the progress of mankind, and you will look at the bronze cannon in the near future...... After all, this is for temporary use......"

Captain Bao Wei argued: "Wan Zhu's family, it can't be said to be used temporarily, if dozens of such cannons are fired together, there is no need to hit twenty times in a row!" ”

Wan Shida smiled, this half-sized man didn't understand what he meant, but he didn't need to understand it now, wait until he looked at the bronze cannon.

Huang Zu watched all the test processes without blinking at that time...... He didn't show the excitement like others at that time, but in his heart, he was turning the river and the sea.

In his mind, the so-called formation he had been studying, and he felt that he had finally found the true direction!

Artillery, as long as there is this kind of artillery that moves freely, what long spears and short knives, plum blossom fish scales, and Tiangang gossip are all in vain...... He drew on the ground with a tree branch, and felt that his thoughts were getting clearer and clearer.

In the end, he couldn't calm down anymore, and this night he went to the bamboo building in Wu Dapeng City.

Huang Zuxiang said: "Lord Shibo, the sea-proof embankment has been built, and the adults said before that the completion of this matter is the completion of eighty percent of the overall work...... Moreover, the excavation of the first-class salt pan will be completed immediately, as for the second-level salt pan...... I don't know how to use the mule and horse cement in the next place, and it can't be of much use, so it's better to let someone else do it, and I want to practice the formation now...... This is a big deal......"

Wu Dapeng Shibo kept looking at the young Huang Zu's head and said, "You let that Nana come in first, don't act like blocking my door!" How bad the impact is......"

Okay, Huang Zuxiang summoned Nana in and asked her to find a place to sit down.

Wu Dapeng stared at Huang Zu's eyes and said, "Talent, what does a real talent need?" ”

"Talent, of course!"

"! I've seen too many talented badas...... You say it again. ”

"German word first!"

"! The more you emphasize that others should be virtuous, the more virtuous people are...... Again! ”

"Benevolence, righteousness, courtesy, wisdom, honesty and trustworthiness ......"

"Huang Xiangshou, it's better to change that benevolent character to a human person......"

“……”

Wu Dapeng smiled after seeing his embarrassment, and said, "What I said is simple common sense, not advanced at all...... A talent, he should treat himself as a person when he is not as good as others; When you are on par with others, treat others as human beings......"

Huang Xiangshou took a breath and said, "The old and the old, the young and the young? It's a sure ......."

"But it has to come first...... For example, if you can let that Nana survive, I appreciate it, humanity is the most important thing for a talent......"

Huang Zuxiangshou made an expression that I had been taught at that time, and immediately said, "What I want to say next is ......"

Wu Dapeng Shibo knew that he was a hypocrisy, so he immediately interrupted him and said, "There is a second one, that is, faith, which should be ranked second...... We've agreed before, and we'll talk about it until you've built the salt works......"

Huang Zu said: "It is true, but there are big and small things...... If the formation I envisioned is useful, it's hard to say that Lord Ichibo can go down in history......"

Wu Dapeng said with a smile: "Without real human civilization and the true spirit of contract, all history will be revised...... It's a joke that goes down in history, and everything is constantly arguing and changing......"

Huang Zu was speechless, it was the first time he was so excited to see Wu Dapeng......

"So, you still have to do your job well, and then we'll talk about other things, whether things are important or not, it's really up to you to judge......"

Huang Zuxiang looked at his resolute appearance and turned around helplessly.

The Nana immediately trotted to follow, not wanting to stop for a second.

Wan Shida said to Wu Dapeng: "His thinking is all set, it seems that it is difficult to change ......"

Wu Dapeng said: "Let time convince everything...... However, this time is just to improve the authority of Bao Wei and Guo Beyu in the company......"

Wan Shida suddenly understood Wu Dapeng's true intentions, and thought about it for a while, it was right to do so, but the two of them were only half the size, and they might not be strong enough at that time.

Wu Dapeng said meaningfully: "What are you afraid of? They command the guns, and we gave them to them. Besides, it's terrible at this level at the moment, and with the salt field we have potassium chlorate...... It's the killer that defeats Black Fire/Potion......"

Now, Wang Defa is teaching Zhang Guoan and his family to hang up the phone and use the laboratory method to process sulfuric acid.

Although there was not much sulfur left with them, because they had seized a batch of inferior black fire/medicine, if the amount was increased, it could still be used to open stones, but they did not dare to use it on arquebuses and artillery, and they did not count what others had made.

The feasibility of the laboratory method for processing sulfuric acid is that it can allow Zhang Guoan to have an intuitive understanding of sulfuric acid production and better understand the soil method of sulfuric acid designed by Wang Defa.

As early as the 8th century, Chinese Taoist priests were able to process sulfuric acid.

The oldest production method is to use alum, that is, ferrous sulfate, as raw material, and calcined it in a distillation kettle to produce sulfuric acid.

Therefore, ancient alchemists called sulfuric acid "alum oil".

During the calcination process, the alum decomposes and releases sulfur dioxide and sulfur trioxide, of which sulfur trioxide and water vapor condense at the same time to obtain sulfuric acid.

However, they just use it to refine all kinds of terrifying imaginative pills, and they also give people to eat, claiming to be able to achieve something...... It's not intentional murder, it's a well-intentioned murder because everyone believes it's useful.

Wang Defa directly designed it to be produced by the contact method, and everything was produced by the local method.

The specific idea is to burn sulfur directly in a cast iron reactor to generate sulfur trioxide vapor and react with water directly into an elevated porcelain tank...... They don't have a catalyst, they don't have a way to guarantee a charge reaction, everything works with just a sense of principle.

Under the guidance of Wang Defa, Zhang Guoan tried it with a small amount of sulfur, and then his face turned a little pale, and said: "No, no one can stand this sour mist......"

Wang Defa said: "There is no way, I can't find a better way to close it, you can arrange for Xiaoliu to beg those people on the island to process it specifically, don't teach half of the children to do this......

The captives were sent to the island of Xiaoliuqiu, where they were given tools for labor, and then they were given food for three days, and they were required to deliver it once every three days, and during these three days they had to do corresponding work, such as mining struvite, such as burning lime, such as taking care of peanuts that were originally grown by the natives...... The natives were repatriated because they found that they still had some ability to process bamboo.

Song Ziqiang was worried that they would be able to run, such as making wooden chops or something......

Wu Dapeng assured: "It is impossible to escape, the indigenous people can tie up bamboo rows and run to Pinghu Island to steal dry rice, that is driven by profits, but they have no way to escape...... Running back to Huangdao on a raft? Even if it did, how would they explain where the Tatar officers went? Are they not afraid of each other having informers? Running back alone? Laugh and talk, I'll let them keep an eye on each other to the death......"

Wu Dapeng smiled slightly, very sinister.

Wu Dapeng gave them an order that if there was one person missing, he would select ten people to hang them!

The person in charge of Xiaoliuqiu Island is still Yao Mai...... Let him find a few assistants and equip them with a few knives.

Later, Wu Dapeng's judgment was proven, and they really watched each other very closely.

Wu Dapeng commented: "The kindness in human nature can be used; The evil in human nature can also be exploited. ”

Song Ziqiang said: "You are really bad......"

Wu Dapeng said: "It's not bad, we don't want to achieve a bad result, that's it." ”
