"Brother, this security team is no longer more than 100 people, but 500 people. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 info" Chen Dafa said with a smile.

"Five hundred? How did there be so many more people all at once? What is Mr. Zhao recruiting so many people for? Wang Zhutou was taken aback, and he said in his heart, this is all about the number of people in a thousand households.

Thousand households are a kind of military position, is five products, the Ming Dynasty has ten hundred households under the jurisdiction of a thousand households, each hundred households under the jurisdiction of 100 soldiers, ten small flags, two general chess, so a thousand households under the jurisdiction of 1120 soldiers, but in the middle and late Ming Dynasty, political corruption, officers deduct military salaries, sergeants fled seriously, in most cases, a thousand households of soldiers count the old and weak has been less than half of the original people, thousands of households can fight only one hundred and ten families, the rest of the people just make up a number.

When Chen Dafa heard this, his smile disappeared suddenly, and he said: "Brother, you don't know yet, Mr. Zhao's security team escorted the goods to Ji'an Mansion some time ago, and the goods were intercepted halfway, and the goods were robbed, and even the escort personnel heard that there were many dead and injured......

"Huh? Is there such a thing? , why didn't Mr. Zhao come to report the case? Wang Zhutou asked in surprise.

"Well, I don't know about this, maybe Mr. Zhao has his own ideas." Chen Dafa said thoughtfully.

Wang Zhutou thought about it, turned around and left. "Brother, why are you leaving, we two are still going to drink......" Chen Dafa hurriedly said.

"No, next time, I have to go back to the county government and tell the magistrate about this, he values this Mr. Zhao very much." After saying that, he ran out like a gust of wind.

Anxious to enter the county office, Wang Zhutou told Song County Ling and Master Niu about it

"This Zhao Mingyuan, he didn't notify the official when such a big thing happened, it's really ...... Master Niu, you and Wang Zhutou take some people to Mingfeng Village to learn about the specific process of the incident and ask Zhao Mingyuan what he thinks. ”

"It's my lord!" The two of them gave up.

When they arrived at Mingfeng Village, Zhao Guohua took the county government and his party to the brigade headquarters of the security team, served tea, and Master Niu learned the details of the incident.

After listening to the whole thing, Master Niu said: "Brother Mingyuan, I agree with your analysis, this thing is done so cleanly, it is indeed prepared, so let's take us to the scene to take a look, let Wang Zhutou see if he can find some clues, after all, he has handled many cases." ”

"Okay, I'll take you there." Saying that, Zhao Guohua walked out of the team headquarters first.

"Kill! ......" A loud roar came, startling everyone.

Master Niu and Wang Zhutou stood still, looked at the training ground, and saw a team of security guards lined up in a neat queue, under the command of a person in front of the queue, holding a wooden stick, taking turns to shout at the chest and abdomen of the wooden man and stabbing violently, the wooden man was stabbed "tom", looking at the accurate assassination part, listening to the tom stabbing wood, the two of them turned a little pale, and then looked at the sturdy security team members in a neat queue, Master Niu sighed and said: "Brother Mingyuan, you are a good soldier, I can't believe you're so proficient in military training. ”

Zhao Guohua smiled and said, "These soldiers are not elite soldiers, and they are far from the standard of elite soldiers. ”

"Oh, so what is an elite soldier?" Master Niu asked.

Looking at the security guards on the training ground, Zhao Guohua said: "Immovable like a mountain, moving like thunder, under an order, ten thousand people strive to be the first to see death as home, defeat is not discouraged, victory is not arrogant, fight can not be broken and dragged down, this is the elite soldier." ”

"Oh, my mother...... Is there such a soldier? Wang Zhutou said in surprise.

"Yes, there are such soldiers, I have seen such soldiers in Huaxia Kingdom." Zhao Guohua said affirmatively.

Hearing these words, Master Niu sighed and said, "This Huaxia Kingdom is really a magical place. ”

After watching the training of the security team for a while, everyone walked out of the playground and rode towards the place where the goods were robbed.

Half an hour later, the group arrived at the scene, looked around at the environment, Wang Zhutou said: "It seems that this is a case done by a veteran, and he is very familiar with the terrain, this place is at the junction of Yongxin County and Ji'an Mansion, and the officials on both sides can blame each other for this matter after the accident, it seems to be a powerful character." So saying, he dismounted and went to survey the scene.

Everyone looked at him quietly. Wang Zhutou walked while looking at the marks left on the ground, and sometimes squatted down to observe carefully, carefully looking for the traces left after the crime. After a long while, Wang Zhutou slowly walked over.

"Can Wang Zhutou see some eyebrows?" Master Niu asked.

Shaking his head embarrassedly, Wang Zhutou said: "I'm ashamed, these thieves are too cunning and meticulous, and they can't see many valuable clues." ”

Looking at Zhao Guohua, Master Niu asked, "Brother Mingyuan, what should you do about this?" ”

Zhao Guohua said: "Thank you Lord Song, Master Niu and the county government brothers for their concern, I am investigating the whereabouts of the thief in the near future, once there is progress, I will ask you for help, this is a little meaning, please accept it." After speaking, he asked Zhang Chong to take out one hundred taels of silver, Master Niu and Wang Zhutou each thirty taels, and the rest of the catchers each had five taels.

Everyone excused themselves and accepted it, and then they said goodbye and broke up.

Back in the security team, Zhao Guohua began to think about how to make granular gunpowder.

Gunpowder is a mixture of three powders, potassium nitrate, sulfur, and charcoal. This mixture is extremely flammable and quite intense to burn. This is because potassium nitrate is an oxidizing agent that releases oxygen when heated. Sulfur and carbon are susceptible to oxidation and are common reducing agents. When they are mixed and burned, the redox reaction proceeds rapidly, releasing high heat and producing a large amount of gas. If the mixture is wrapped in paper, cloth, skin, or stuffed in a clay pot or stone hole, and when burned, the volume suddenly expands and increases to several thousand times, and the explosion will occur. This is the principle of the incendiary explosion of black powder.

In the early days, gunpowder was powdered black powder in barrels, and due to the relatively light mass of the toner during transportation, the toner floated due to factors such as bumps and vibrations. Resulting in the inhomogeneity of the composition of black powder. The problem of delamination occurs, and the sulfur is often deposited at the bottom of the barrel after long-distance transportation, and it must be stirred again before use, otherwise it will greatly affect the power and it is very troublesome to use. Moreover, powdered black powder has strong water absorption! (Activated carbon or saltpeter are strongly absorbent). And black powder with a water content of more than 2% is basically unusable. Therefore, whether the powdered black powder can detonate or not, and what it will look like, is completely up to fate. The water absorption of granular gunpowder is greatly reduced.

Granular gunpowder is more powerful than powdered gunpowder, one is the uniform proportion, which is conducive to the combustion of gunpowder, because gunpowder granularity, there is enough air between the particles, and the reason why the granularization will burn better is because there are gaps between the particles, and the flame will spread between the gaps when the gunpowder is ignited, so the combustion is sufficient, and the powdered gunpowder burns only on one side, and the particles are all burned at the same time, so the combustion effect will be better, which increases the thrust and improves the range and hit rate.

And because of the full combustion, the residue in the gun boring will also be greatly reduced, the reliability of the gun will be greatly improved, the blockage may be reduced, the time spent cleaning the gun boring will be reduced, the granule gunpowder will be loaded faster, and the firing rate will be increased.

Although the flash velocity of granular gunpowder, that is, the combustion speed is not higher than that of powder gunpowder, sometimes it may be lower, especially for powder gunpowder of loose charge, the flash speed is very high. But the flash velocity of powder gunpowder was uneven. Flash speed is not always better. Some parts of the powder gunpowder have a high flash velocity and react first, while other parts cannot be burned completely, and there will be a large amount of residue. In addition, those high-speed parts, although they release most of the explosive energy, can be regarded as a small-scale reaction in a low-pressure cavity because there is no reaction in the surrounding area, and the detonation power is weak. However, the flash velocity of the granular gunpowder is the same, the overall reaction is complete, and it is constrained by the container together, so the detonation power is stronger.

As an arsenal firearms administrator, Zhao Guohua knew that the manufacturing process of high-quality granular gunpowder was quite complex. It is not so simple to make: first of all, the black powder powder is pressed into a high-density and uniform composition of the medicine cake, then the medicine cake is broken to obtain particles, the powder and too fine particles are removed through sieve, and then polished, and then sifted to obtain the particle gunpowder of basically the same size.

Granulated black powder is good for maintaining the uniformity of the ingredients during transportation, so it is relatively powerful. The optimal ratio of modern black powder is 75% nitrate, 10% sulfur and 15% charcoal;

"Let's try to do it first, it's better to do than to wait, time waits for no one." Zhao Guohua rubbed his head and muttered to himself.

As soon as he said it, he first sent people to the county seat, sold a weighing instrument for gold and silver, and began to make a small amount of granular gunpowder.

In order to train the firecrackers, Zhang Shun selected ten security guards from a squadron according to Zhao Guohua's requirements, and under Zhang Shun's guidance, the security guards slowly became familiar with the operation

"Charge...... Raise your gun...... Aim...... Ignition...... Shoot......" Zhang Shun shouted the order, directing ten security guards to practice shooting in a valley outside the village.

"Smack...... Syllable...... The sound of ...... firecracker rang out one after another......

A member of the team loaded the gunpowder, took a look, and asked cautiously: "Captain, this firearm has been hit so many times, it won't blow up, right......?"

"Snap", Zhang Shun patted him on the head with his hand, and scolded with a smile: "This is what I and the captain have carefully checked one by one, not those rags are comparable, you can fire with confidence, the chamber is blown up, Lao Tzu will pay you for your life......"

"Okay, so I'm relieved...... Hehe...... "The security guard smirked.

Besides, after Niu Huan and Ma Bao accepted the task of investigating and intercepting the goods and attacking the traces of the thieves in the escort team, the two changed their original clothes and pretended to be hunters and wandered around the mountains near Jinggang Mountain.

"Niu Huan, our brothers ........." I have also run a lot of Lu these days, and the larger mountains near here have also been explored, except for the Qinglong Village at the five major whistles, there are no more large bandits, it won't really be the people of Qinglong Village." Ma Bao sat on a clump of dead grass on the mountain path and ate pancakes, and said that there were two pheasants and three hares that had been shot dead on the ground.

Looking at the mountain peaks in the distance, Niu Huan said: "What you said is not unreasonable, after our investigation during this time, I also think that Qinglongzhai is very suspicious, eat something, wait for the two of us to go over and have a look." Let's see if I can get a little bit of news out of the mouth of the little minions guarding the gate. ”
