Li Yongfang did not dare to come back and talk to Huang Taiji about this matter.
He just reported the nine-shot fire door gun he picked up and got into trouble. Huang Taiji asked him to copy it because he had all the firearms of Jiannu. If he didn't agree to the job, Huang Taiji would definitely find an excuse.
, set up a separate firearms force to share his power. This is what he does not want to see.
However, the imitation that followed would kill him.
The barrel kept exploding, and he didn't understand why Yang Fan could make it so thin and light, but he kept thickening it and it still turned out to be unsafe.
Only then did he realize that although this thing seemed simple, there were actually many tricks in it. And through practice, he understood that this thing and the casting cannon are actually the same technology. If he can break through this technology, he can break through the casting.
Cannon technology.
In this era, the Western cannon casting technology had a yield rate of only 15%. The Qing Dynasty could not cast cannons at all, and their technology was far behind the Ming Dynasty.
Huang Taiji urged him urgently. Fortunately, he later established a relationship with the Zheng family in Fujian. The Zheng family's merchant ship shipped to Yingkou a ship of open-hearth steel obtained from Zunhua. This solved the material problem.
These gun barrels made of open-hearth steel never exploded. But they could only be forged into gun barrels, but drilling couldn't be done. They didn't have high-hardness alloy steel tools, so naturally they couldn't drill holes. In the end, they had to make these barrels.
The steel pipe is made into a blunderbuss.
These blunderbuss made of open-hearth steel are one-quarter lighter than the original barrels made of wrought iron, and can be loaded with twice as much propellant, and the range can reach an effective range of one hundred meters. This is what made him famous in Huang Taiji
Got a job there.
After this incident, he would not say a word about Yang Fan's firearms even if he died. Therefore, he did not mention the gunpowder-propelled grenades that he had seen during the Battle of the Grasslands.
Huang Taiji knew at first sight that something was wrong. Every time a new weapon appeared that exceeded his knowledge, it would inevitably lead to huge casualties. This time it was probably not a good thing either.
Seeing the front row, there was a bang, and a carriage was blown into the air. The entire heavy carriage flipped backwards and got stuck in the array of infantry and archers holding shields and big bows.
The cart was so heavy that it suddenly destroyed the array behind it. There was a burst of dust, the wooden shield of the cart cracked, wooden blocks flew across, and the sand and dust inside almost obscured the realization.
The first shot set the benchmark, and the next fourteen shots followed one after another, with stacks of fireballs reported from the front row. These explosives fried with fertilizer and sugar were more powerful than the previous sawdust, fertilizer and explosives. This is the latest recipe from Syria in the Middle East.
.
White sugar explosive is 1.5 times more powerful than TNT. Under certain circumstances, the power of sugar explosive can be made into an explosive equivalent to the power of an aerial bomb.
After boiling the white sugar into syrup, and mixing it with an unnamed fertilizer in an unspeakable proportion, you can use a frying spoon in the kitchen at home to make a high explosive with an explosion speed of 3200 meters/second, or mix it with an unspeakable fertilizer in an unspeakable proportion.
An indescribable substance can be made into rocket propellant.
And these methods have been verified. In the Syrian battlefield in 2012, the opposition used sugar to make explosives when they lacked weapons. The fool has been active in the Middle East recently and has obtained these formulas. Now Yang Fan’s Congreve
The rocket has been discontinued.
The rocket arsenal in Xincheng has begun producing Syrian version rockets made from scrap steel pipes. The warheads of hand grenades, naval fire rounds, and gunpowder-assisted grenades have all been replaced with this new type of filled explosive. The power has increased from 60% to TNT.
, increased to 1.5 times.
Chief Engineer Chang Zhu presides over the Small Arms Design Institute, and their research on fragmentation has made another breakthrough. Now the fragments of explosives are more uniform and denser, and the number of fragments produced per unit area has tripled.
The charge of this grenade reaches two kilograms, which is equivalent to three kilograms of TNT explosives. This is quite powerful, equivalent to a 105mm modern artillery shell. It is just a trivial matter to blow up a car.
The bridgehead suddenly exploded into a sea of fire. The huge power of these explosions blew up the attacking military formations. Some fell on the carriages, and some jumped over the carriages and fell into the military formations behind. Every explosion,
Huge fireballs rose up, thousands of fragments swept around, and all living things within a 25-meter radius of the explosion were torn into pieces by the shock wave. Many people fell off the bridge and fell into the cold river.
Now that the climate is getting warmer, the river ice is beginning to melt, and there is only a thin layer. Once a person falls, he will directly break through the ice and fall into the zero-degree ice water. He will soon freeze to death. This is why the positive red flag must be passed.
The reason why they attacked the bridge but did not cross over from the trench.
One is that they don't know how deep the water is, and the other is this mixture of ice and water, which is the coldest. People will get cramps if they go in, and then their limbs will freeze and they will drown in the water. If they don't drown, they will freeze to death.
Huang Taiji silently looked at the mess on the bridge. There were dead bodies on the ground, most of them with broken limbs. The snow-white bridge deck was burned black. The carriages were broken into pieces of wood and were still burning. There were also injuries everywhere.
The person was not dead for a moment, but was still writhing and wailing.
This bridge seemed to be a terrifying Shura field.
This was the first time that the Eight Banners saw what the people who were killed by the intensive explosion looked like. There were no whole bodies, they were all in pieces.
Although they were savage and fearless of death, they were hacked to death with knives and stabbed to death with spears. Although blood flowed everywhere, it was far from the visual impact. There were burning car wrecks and broken limbs all over the place.
The bridge was burnt black.
The attacking troops collapsed all of a sudden. They turned around and ran away in fear, throwing away all the carriages and ladders. It was useless for the officers to kill several of them. Instead, they were pushed down by the swarming troops, and countless big feet stepped on them.
, and soon turned into a puddle of mud.
Huang Taiji sighed, the first round of attack was defeated.
While Zheng Hongqi was attacking the main gate, the Mongols also began their attack on the shantytowns in the northwest.
Balu saw that Zhenghongqi had begun to attack the main gate. He squatted on the street corner and looked carefully for a long time. There was no one there. There was a street, not even a barricade. At the end, he could see a small stone bridge and a tall wall.
The small door on the top. Entering the small door is the industrial area.
"Charge over, hurry up." Balu waved his hand, and five hundred Zarut men, holding shields in their left hands and scimitars in their right hands, rushed into the street quickly. The street was paved with bluestones, and there were two or three people on both sides.
It is a small red brick building with two floors. The doors and windows are blocked with bricks, which looks very strange.
There was no one, and no one fired at them. There was only the rustle of their footsteps on the street. Balu was a little confused, maybe he was lucky and found an unguarded passage.
