"Chichichi..."
A piece of paper fuse rolled with some gunpowder was burning rapidly, emitting sparks and making a "chichi" sound. In a blink of an eye, the flame was sent into a copper kettle with a wooden tube and silk cloth blocking the spout. .
Inside the copper pot, there is a full half pot of powdered gunpowder. It is not a "high-end gunpowder" made of higher-purity potassium nitrate, sulfur powder, and carbon powder evenly mixed according to a formula of 7.5:1:1.5, nor is it a mysterious granular black powder.
Instead, the Han craftsmen from the Kingdom of Jin used the formula of Tribulus terrestris gunpowder in the "Martial Classics General Essentials" that the Liao people had spent a lot of money to obtain from the Song Dynasty as a basis, and referred to the recipe brought back by Xiao Zhonggong. The new gunpowder prepared after making powdered gunpowder in the pot - actually removes tung oil, small oil, wax oil, yellow wax and other things that may make the gunpowder sticky. After all, the gunpowder poured out of the copper pot is dry. of. However, the two traditional Chinese medicines Zhuru (a traditional Chinese medicine used to treat coughs) and Maru (a traditional Chinese medicine used to treat dizziness) are still retained.
Apart from the two very expensive Chinese medicines, I don’t know what they are used for? The ingredients of this half pot of gunpowder include flame salt, sulfur, charcoal powder, asphalt, dry paint, etc. The ratio is 40:20:5:2:2. The proportion of fire saltpeter is too low, the proportion of sulfur is too high, and the proportion of charcoal powder is too low.
In addition, the purity of fire saltpeter and sulfur is not ideal, and it is not as good as Zhao Kai's "Made in Luoyang".
However, these formulas are wrong, and the purity of the key materials is not ideal. The gunpowder is still extremely easy to burn! When they encounter an open flame, they are quickly ignited and burn violently, producing a large amount of gas and heat.
Since these gunpowders are burned in a closed container, the large amount of gas generated when the gunpowder burns cannot be dissipated in time, which will increase the air pressure in the container... When the air pressure increases to a certain level, the container The shell cannot withstand the huge pressure and will be crushed, which is an explosion!
The formula of gunpowder is not right, and the purity of fire salt and sulfur is not very high, which will affect the burning speed of gunpowder and the total amount of heat and gas released.
However, the total amount of heat and gas can be increased by increasing the charge.
The burning speed of gunpowder, that is, the release speed of heat and gas is too slow, can only be compensated by a strong shell - burn it for a while, as long as there is enough gunpowder, enough will be burned to cause a big explosion. The high pressure gas required for the explosion!
In fact, a strong shell is a key to the creation of the big bang!
If there is no such shell, such as a paper shell, leather shell or paper shell, it does not take much high-pressure gas to tear it into pieces. Therefore, no matter how good the black powder is filled in "paper bombs", "leather bombs" and "porcelain bombs", it is difficult to generate enough high-pressure gas to push the fragments and various fragments or projectiles filled inside the bomb.
Only gas with high enough pressure can give enough kinetic energy to the fragments and projectiles, allowing them to fly in all directions at a fatal speed, causing fatal damage to all creatures that stand in front of them!
Of course, the bigger the shell strength of the bomb, the better. If it is too strong to be broken, or if there are too few fragments, the effect will not be ideal.
Therefore, the performance of the cast iron shell under the current smelting technology is not as good as that of the bronze or brass shell. The quality of the current cast iron is difficult to control, and it is hard to say how much air pressure it can withstand, so the appropriate amount of charge has become a mystery. Already......
"Rumble..."
Somewhere in Yehuling, there was suddenly a loud sound that shook the mountains, and then a cloud of thick smoke rose up!
This momentum and movement far exceeded a group of Wanyan's understanding of gunpowder weapons. Even Wanyan Zonggou, who came from Kaifeng Mansion, had never seen such a shocking scene of firearm explosion. He opened his mouth like a bear who had never seen the world.
"It exploded, it exploded, it finally exploded... Your Majesty, did you see it? This gunpowder is indeed much more powerful when it meets copper!"
A group of people watched the explosion of the fried pot, but Wanyan was still calm, but Xiao Zhonggong, a loyal minister, couldn't help but cheer.
Because before this bomb exploded, there was already a bomb that failed to explode due to insufficient charge and became a "dumb pot" - the amount of charges in the previous bomb was based on the original bomb Xiao Zhonggong brought back. It came from a pot, but it failed to explode because of the poor quality of the gunpowder.
Seeing that the frying kettle didn't explode, a group of Wanyan all had long faces, as if they were very unhappy after being deceived.
Xiao Zhonggong was frightened when he saw the faces that were about to bite someone!
She quickly asked the craftsmen to double the charge. The original charge for the explosive pot was too much (because the performance of powdered gunpowder is relatively poor, and there will be delamination during transportation, which further affects the performance, so Wu Meiniang Just increased the amount), and now Xiao Zhonggong has doubled it. The craftsmen below were also afraid of death, so they secretly added some more. It turned out that the fried pot that had just exploded contained two kilograms, two or three ounces of medicine... almost half of it was wasted!
Oh, it's not a waste. When Xiao Zhonggong saw Wanyan's expressions, he knew that the gunpowder was added correctly.
No one among Wanyan looked at Xiao Zhonggong now. They all came out from behind a newly built earth wall and walked towards the place where the explosion had just occurred.
In the grass, a big pit suddenly appeared! Around the pit, there were dozens of scarecrows lying in random directions.
In order to test the actual lethality of the explosive pot, Wanyan Wu Qimai also had dozens of straw men wearing iron armor placed around the explosive pot, but now they were all blown over.
Not only were they overturned, but most of the scarecrows had a piece or even a few pieces of explosive pot fragments or iron sand embedded in their bodies. When the iron armor on their bodies encountered these fragments and iron sand, they seemed to be almost made of paper, and they were all penetrated.
If this scarecrow had a life, he would definitely not be alive now!
"This, this is so powerful, isn't it?" Wanyan Xiebao squatted down and looked at the scarecrows that had been blown up by the bomb one by one. His face became livid the more he looked at it, "A pot is so powerful, if there is a How can our Jurchen heavenly soldiers defeat one hundred and eighty thousand bombing pots..."
"Xiebao, stop saying a few words!" Wanyan Zonghan heard his son Xiebao talking nonsense again, and quickly yelled at him - this boy's crow's mouth is so evil, it is too lethal to the Kingdom of Jin, and it is too harmful to the Kingdom of Jin. The Song Dynasty was of no use... Wanyan Zonghan often asked him to curse Zhao Kai these days. That boy was also obedient. He said that Zhao Kai was going to die every day, but it was of no use at all!
Wanyan Zongbi didn't know how powerful Xie Bao's crow mouth was, so he still spoke for him, "Nianhan, Xie Bao is right... I'll knock down dozens of people with just one pot, how can this fight be done?" beat?"
"This fight... is not going to happen!" Wanyan Zonghan shook his head repeatedly - his son's crow's mouth had already said that and he still slapped him!
"No fight?" Wu Qimai frowned deeply, "Is this trip in vain?"
"Your Majesty," Xie Bao suddenly interrupted, "Actually, it's not that we can't fight... It's just that we have to be on the defensive in Hebei to avoid running into the elite Song Army equipped with a large number of explosive pots."
"On the defensive in Hebei?" Wanyan Zongbi asked, "Then where to take the offensive? Hedong?"
"Hedong will naturally be attacked," Wanyan Xiebao said, "but that is just a feint attack, allowing Hebule to send troops... to attract Zhao Kai to return from the northwest."
Zong Bi asked again: "Then where should we fight?"
Wanyan Xiebao smiled and said: "If we can't attack the center, of course we have to attack the two wings! The left wing goes out to the northwest, and the right wing goes to the southeast. No matter how powerful Zhao Kai is, he can only take care of one end. We can always succeed at the other end."
"When we go to the southeast, we are going to fight Zhao Huan..." Wanyan Zongbi asked again, "Who are we going to fight when we go to the northwest?"
"The German troops came out of Tianjin, and then went along the Yellow River to Xingqing Mansion. After arriving at Xingqing Mansion, they helped the party members to counterattack Lingzhou." Wanyan Xiebao said, "Zhao Kai sent troops to Lingzhou all the way to conquer Xixia. Are you going to be out? Since he only wants Xixia to be out, then we will do the opposite and prevent Xixia from being out!"
I have to say that this oblique guard not only has a powerful crow's mouth, but also knows some strategic layouts!
Xie Bao added: "But this road is just a diversion... After all, Zhao Kai's advantage in the northwest has been established, and we can't really send out a large army to support Xixia. So our real goal should be two The land of Huaihe!"
"Take Lianghuai?" Wanyan Zongwang frowned, "Lianghuai is so hot in summer, how can it be a place where my Jurchen will stay for a long time?"
Half of his life was "killed" by the heat, and he is still frightened and reluctant to go south.
"I'm not afraid of the heat!" Wanyan Zongbi patted his chest, "I'm going to attack Lianghuai... Lianghuai is a prosperous land!" He glanced at Wanyan Zonggou again, "And there's Wuli sister leading the way. It won't be bad."
Wuli sister, Wanyan Zonggou, felt a little complicated after hearing this... Of course he wanted to be the emperor, but it was too ugly to lead Jin Bing to fight Lianghuai. And now that Zhao Huan is not dead, it is not his turn to be the emperor!
"What about Zhao Kai?" Wanyan Zongwang asked, "Do you really want to ignore him? He is getting bigger and bigger now and is becoming more and more difficult to deal with!"
Xie Bao said with a smile: "We just want to make him run northwest and southeast for a while! And we have a purpose for sending troops to the southeast!"
"What?"
"Robbing for copper!" Wanyan Xiabao said, "There doesn't seem to be much copper on our territory! And the southeast of the Song Dynasty is the place where copper is produced and smelted in the world. If the future conquest of the world is to be won by exploding pots, The winner or loser depends on who has more copper! Zhao Kai already has more copper than us, and Zhao Huan also gives Zhao Kai 6 million yuan a year. If this continues, how can we get it?"
Zhao Huanzhen was sitting in the east of the Yangtze River, and disaster came from the pot... Moreover, the annual salary he gave to the "emperor's brother" Zhao Kai was not all money. Three million was in rice, and one million was in rice. It's silk, one million is tea and silver, and only one million is copper coins!
But Wanyan Xiebao ignored the facts and regarded all the six million as copper coins!
