In the tent of the military camp, the people who were shocking the huge profits of the charcoal were blinded by the sudden news of the craftsmen of the ordnance institute. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo。 qВ5//

When Zhao Lei heard the words of the black-faced craftsman, his first thought was to block the news, he immediately threw away the spatula, and as soon as he hit Han Qi beside him, Han Qi politely invited Pan Fusheng and other people who had nothing to do with the new army and the imperial court out of the barracks.

"Black powder has been made!" Seeing Pan Fusheng and the others leaving, Zeng Gongliang, who knew the inside story of black powder, asked in ecstasy about the craftsmen who came to report.

"It worked, it was tested just now, and the power of the explosion was very objective." Hearing Zeng Gongliang's question, the craftsman replied with a happy face.

"Right away!" After Zhao Lei finished speaking the envelope, he couldn't wait for Han Qi to return, and took the generals and court officials of the New Army behind him and walked towards the arsenal workshop that had been moved to the New Army camp.

The military camp covers an area of five miles, and there are not only places for the new soldiers to live and train, but also various warehouses and a secret research institute for the new army's logistics yamen.

The armory managed by Zeng Gongliang is in the secret place of the barracks area of the new army barracks, it is a secret place surrounded by a three-zhang high wall, and the surrounding is heavily guarded, and a battalion of thousands of soldiers take turns to guard near the ordnance station, unless someone has wings, they must not be mixed into the ordnance station.

The ordnance institute in the military camp is not only researching the formula of black powder, but also responsible for the production of rocket cars, fierce fire oil and other confidential items required by Zhao Lei, as for ballistas, various artillery trucks and other things. There was no need for too high secrecy, and the production line was left in the original ordnance station.

When Zhao Lei led a group of new army generals and court officials behind him to the armory, the craftsmen in the armory were shouting to celebrate the success of the research.

"Lord Zhao! You came, the black powder was finally successfully studied, and you didn't expect that the saltpeter would reach seventy-five percent. When the sulfur reaches 10 percent and the charcoal reaches 15 percent, a strong explosion will occur! Seeing Zhao Lei's arrival, an old craftsman with white hair said to Zhao Lei with a look of surprise.

"All researchers will be rewarded with 100 taels of silver, and the salary will be doubled at the end of the month!" Seeing that all the bows and arrows studying black powder in the ordnance institute were tired and black, Zhao Lei said loudly with emotion in his heart.

One hundred taels of silver is almost equal to ten years of income for the craftsmen, and when they heard Zhao Lei's reward, the craftsmen cheered excitedly.

"Tested on grenades and mines?" Zhao Lei stopped the cheers of the craftsmen. asked the old craftsman beside him.

"I've tried it, but the explosion isn't as powerful as adults say! Is it that the research has not been successful? When the old craftsman heard Zhao Lei's question, he immediately frowned and said.

Hearing the word "but" in the old craftsman's mouth, Zhao Lei was startled, thinking that there was something wrong again! But hearing is only a matter of power. Zhao Lei breathed a sigh of relief.

Therefore, it is known that the cause of the explosion of gunpowder is because saltpeter decomposes and releases a large amount. Oxygen, which causes charcoal and sulfur to burn violently, instantly produces a large amount of heat and gases such as nitrogen and carbon dioxide, which expand dramatically due to the volume. The pressure increased violently, and an explosion occurred.

In later generations, the burning of gunpowder generally caused the gas to expand tens of thousands of times, but the refining technology of the Northern Song Dynasty was not up to par. Whether saltpeter, sulfur and charcoal, there are too many impurities in it, so it cannot be fully decomposed and burned, and the gas expands thousands of times at most, so the power of the explosion will be greatly weakened.

"Let's go, let's see!" Zhao Lei knew in his heart that making perfect gunpowder was impossible now, in his opinion, as long as the power was enough, with the financial and material resources of the Great Song Dynasty. It is definitely able to replace quality with quantity and give the enemy large-scale lethality, so he waved his hand to the old craftsman without care.

"What is black powder? What are grenades and mines? "It's good to be happy to sort out the people brought by Zhao Lei, in addition to Zeng Gongliang, Wang Su and Ding Du, Yang Zun, Gao Zunping, Shi Yuanchun, Gan Ling, and Pang Ji still don't know the research of the Ordnance Institute, and they all asked Zhao Lei suspiciously.

"A new type of weapon, from the gunpowder weapons exhibition, the lethality is amazing, you will know when you see it in a moment." Zhao Lei explained simply, and led everyone towards the test room.

The test room of the Ordnance Institute is a specially made room instructed by Zhao Lei, and the whole room is made of thick iron sheets. Crafted from rammed earth and with incredible defense, the room is filled with straw man targets dressed in thin iron armor, a room specially built for testing various gunpowder weapons.

In the empty test room, Zhao Lei and a group of court ministers stood behind a high wall, which neatly divided the test room into two, and there were at least ten door openings without door panels on the high wall for the testers to enter and exit and throw test products.

"Lord Zhao, the black powder has just been successfully made, so only a few grenades and mines have been made!" The old craftsman took three ugly iron peaches and two ugly iron watermelons, handed them to Zhao Lei and said.

Zhao Lei picked up an iron peach that could be held in the palm of his hand, looked at the iron pimple with a pitted appearance, and sighed in his heart that he had come to the Northern Song Dynasty for so long and finally made a strong weapon across the era.

"What kind of grenades and mines are these? What are they for? Pang Ji looked at the iron pimple in Zhao Lei's hand and asked with a questioning expression.

"Just look at it, you're all hiding behind a wall!" After Zhao Lei shouted orders to the others, he saw that everyone was hiding, pulled off the string on the grenade, and threw it towards the middle of the straw man target in the test room.

Rumble! Zhao Lei and the others, who were hiding behind the high wall, heard a dull sound like thunder, and then felt a large wave of air rushing over, and then smelled the smell of gunpowder smoke all over the room.

"It's thundering." Gan Ling covered his ears in a daze and muttered.

Zhao Lei looked at the shocked and open mouths of everyone behind the high wall, smiled slightly, and beckoned them into the test room.

In the test room, Zhao Lei led a group of people to squat on the charred ground, and several straw man targets next to him were staggered and fragmented.

"The range of the explosion flap was almost six meters, but only a fragment of a grenade within one meter was able to penetrate thin armor. One meter away can only kill and injure places without armor, and the heavy armor within another meter is not damaged at all, it seems that the power of the grenade is still too small, and it does not have much lethality against the heavily armored enemy at all. Zhao Lei covered his nose, filtered the smell of gunsmoke, and then said to several ministers of civil and military affairs who were becoming more and more shocked around him.

"It's still too little. Lord Zhao! What else do you want! Look at the target near here, a grenade can cause at least hundreds of scars, there is no regular scattering at all, you can't block it, with this thing, the heavy armor has a fart use, no matter how powerful the armor is, it is impossible to protect the whole body, and when you encounter this kind of irregular grenade, you will be sent to death. Think about it, if tens of thousands of grenades are thrown out at the same time on the battlefield, even if it is an army of 100,000, it will not be able to stop their power! Shi Yuanchun, a young military general in his twenties with a shrewd and calm face, looked at the shattered straw man who was staggered and blown up by the grenade explosion. said to Zhao Lei with a look of emotion and fear.

"it! How can there be such a powerful thing, as soon as this kind of thing comes out, no matter how good the martial arts practice is, it will be in vain, and if a grenade is thrown over, the iron man will not survive! "The figure is slightly lower than Zhu Dali. It is definitely about two meters, tall and large, and looks fierce. Gao Zunping, the sturdy Bianjing Jiangmen's first master of the younger generation, looked at the tragic situation nearby, smelled the smell of gunpowder smoke nearby, and his ears were still buzzing from the vibration just now, and he scolded with a wry smile.

"It's amazing, gunpowder still has such a great potential to be tapped, it has been used as a comblamenary to burn the enemy's grain and grass is already the best way to use it, I didn't expect it to explode, out of such a great power, with this thing. Do I still need to be afraid of Western Xia and Liao! Pang Ji looked at the explosion of the nearby grenade with a shocked face and muttered.

"You look at the grenade too much, think about the attack range of a grenade, how many soldiers can stand, only a few, even if the standing is a little crowded, at most ten people, and the direction of the grenade's attack is not regular at all, that is, if the enemy is lucky, a grenade may not kill an enemy, if we are lucky, a grenade can destroy all enemies in range, but the enemy is not a fool, once they know the power of the grenade, they will definitely maintain a loose formation, If the cavalry that comes and goes like flying, the lethality should be weakened, the official idea, grenade is the best defensive position with rocket vehicles, crossbowmen, trenches and barbed wire, it is a long-range strike weapon, it can never replace the warrior as the main lethal weapon, against the enemy of the Western Xia and Liao, the grenade is only an auxiliary weapon, the most important thing, is the knife and gun in the hands of the soldier! Zhao Lei looked at a group of civil and military officials of the imperial court who had begun to look forward to the invincibility of the Great Song Dynasty, and immediately poured cold water and said, he didn't want the appearance of grenades to make the Great Song Dynasty arrogant and arrogant, and then immediately prepared to open up the country and promote the world.

"This is a grenade, it is really powerful, it is projected by hand, the sound is like thunder, and the power is amazing! Such a powerful thing, the official has to go and tell the official family immediately! Gan Ling, the inner attendant, looked at the power of the grenade in a daze, and suddenly became ecstatic and said.

"Lord Gan, wait, after we have seen the power of the mines, it is not too late to go to the official's house together!" Pang Ji immediately grabbed Gan Ling and looked at Zhao Lei with a wistful expression.

"Mines must be touched to explode, they are more powerful than grenades, but they can't be moved, let's go outside and see!" Zhao Lei greeted the nearby officials and craftsmen and said.

On a training ground in the military camp, the soldiers who were training disappeared without a trace, and on the training ground, more than a dozen sheep were rampage on the fenced training ground, and Zhao Lei and others, behind the wall far away from the training ground, secretly looked at this side.

"Why haven't you stepped on it yet?" Gan Ling looked at the sheep that did not step on the mines buried in the soil, and whispered in a sharp voice hatefully.

Rumble! Before Gan Ling's words fell, an unlucky sheep finally stepped on the mine, with a deafening roar, a huge wave of air, dust and an unpleasant smell of gunsmoke, and at the same time pressed towards Zhao Lei and others.

On the training ground, more than a dozen sheep were completely put down by two, and three or four were hit by shrapnel flying indiscriminately, and they fell to the ground and screamed miserably, while in the center of the training ground, a small pit half a meter high and one meter long, appeared in front of the stunned observers.

"Tell the new sergeant to add vegetables tonight, mutton steamed buns!" Looking at the shocked look of the civil and military officials around him, Zhao Lei said proudly and happily to Han Qi, who returned to the barracks.
