As early as the beginning of the construction of the cement section burning room, Roland had made plans for the experimental rooms for the following projects. Most of them were built around the North Slope mining area, which could be effectively concentrated and guarded - the construction speed of this kind of earth brick wall and wooden roof bungalow was extremely fast, and it did not affect the construction progress of the city wall.
The saltpeter purchased in large quantities from Liuye Town is transported to nearby warehouses for storage. When needed, it is ground and weighed by servants and sent to bungalows in batches. The same is true for charcoal and sulfur. The handling and mixing of the three raw materials are done by different groups of people, which can minimize the risk of leakage.
Roland weighed out twenty pounds from the prepared black powder and slowly poured it onto a cut sheepskin.
These gunpowder have been soaked, compacted , dried, hammered, sieved and other treatments, and have formed uniform particle shape with excellent combustion performance. In order to prevent static electricity accidents, no metal utensils are used in the entire production process, mostly ceramic or wooden products.
After pouring the gunpowder, Roland stacked the sheepskin layer on top, wrapped it up to three layers, and then tied it tightly with a rope.
Is this enough? "Carter asked. Can this thing in front of him also be called a weapon? Although it is an improved product of snow powder, who can be intimidated by its sound alone? It may be effective against farmers who have never been to the battlefield, and any trained warrior or mercenary will not take it seriously. However... the chief knight carefully considered it. His Highness's recent actions seem unreasonable, but most of the effects are amazing. If the intelligence of evil beasts is similar to that of wild beasts, perhaps this thing will be unexpectedly effective? For example, a loud noise scares them and scatters them, thereby reducing the pressure on the defending team.
Roland stuffed the wrapped gunpowder into Carter's arms, then took a bag of finely ground gunpowder powder for ignition, "It's almost done, let's go outside the city wall, the iron axe should be ready."
About two miles west of the city wall, a piece of open space between the Concealed Forest and the Desperate Mountains is the test area he marked out this time.
Iron Axe and several other hunters had been waiting here for a long time. Except for Iron Axe himself, everyone was a local and one of the best archers. When they heard that the prince had a task for them, they immediately followed Iron Axe eagerly.
Now everyone knows that the new lord of Border Town is never stingy with employment remuneration.
Following Roland's instructions, they set up long wooden poles around them, tied ropes, and formed a security circle for nearly half a mile. Knights were arranged to patrol in the direction near the city wall to prevent anyone from accidentally approaching.
Roland checked around the security circle and nodded, "Did you bring all the prey?"
"Your Highness, everyone is here," Iron Axe dragged a cage forward, and Carter noticed that there were several wild chickens and rabbits inside.
"Very well, place them at a distance of five, ten, fifteen, or thirty steps from the center point, and tie one to each wooden stake."
Carter secretly shook his head and suggested, "Your Highness, I'm afraid the animals you chose won't be tested for effectiveness. They are extremely timid and will scatter at the slightest sound. Even if you can scare them, you may not be able to scare away the demonic beasts."
"Scare away the demonic beasts?" Roland was slightly startled, then reacted, "I didn't intend to scare them away, although the sound of this thing exploding is indeed amazing."
He led the chief knight to the center of the circle, put down the gunpowder bag, made a small incision with a dagger to let the gunpowder leak out. Then he took out a leather bag containing gunpowder powder, sprinkled it from the incision, and retreated while sprinkling.
Today is a windless day, which is very suitable for this primitive detonation method.
After retreating nearly a hundred meters, Roland finally put away the leather bag.
Okay, let's light the fire here, "he estimated the distance repeatedly, confirmed it was correct, and then said to Carter," Go and call the hunters over.
At this moment, Roland was also a little excited. He had already done a small amount of flash test before, and he was not worried about the test results. What he cared about was that this would be a great moment. From today on, the thermal weapon will officially take the stage, and he will be written into history as the leader.
After everyone gathered, Roland lit the gunpowder powder.
Carter lay on the ground, looking at the rapidly receding Mars, feeling somewhat disapproving.
From such a long distance and not being placed in a bronze bucket, it was still a question whether the exploding sound of the snow powder could be transmitted here. His Royal Highness actually made everyone lie on the ground. However, since the Fourth Prince took the lead in doing so, he couldn't say anything more.
The ground in winter is very cold, and you can feel the chill spreading even through the chain armor. Carter moved his body and prepared to turn his chest to the side, when a shocking sound suddenly rang out -
Due to the distance being too close, the explosion and the shock wave almost reached at the same time. He felt his ears buzz and the world suddenly became quiet. The tremor of the earth disappeared in an instant. He looked up and saw a black cloud slowly rising, followed by falling stones and mud like rain.
Roland's impact was much smaller than that of the Chief Knight. Even setting off firecrackers would block his ears, so he immediately prepared for protection after lighting the gunpowder powder. The explosion point was not like in the movies, which would release a huge fireball. The fire flashed away, and a large amount of mud was lifted up by the air wave and rushed into the air about ten meters away. When the dust settled, Roland's only feeling was: the sound was much louder than firecrackers.
As for Iron Axe and the other hunters, they were stunned. Only Iron Axe knew that this trip was to test a new weapon, but he didn't expect the momentum of the weapon to be so amazing.
I'm afraid only the thunder of Heaven's Punishment can compare to it!
Roland stood up and led everyone back to the explosion point. There was a pit half a meter deep on the ground, and the rabbit closest to the explosion center had long disappeared, leaving only a short wooden stake on the ground.
He checked the other animals one by one. The pheasants placed at the tenth and fifteenth steps lay motionless on the ground, obviously dead. Although there were no obvious injuries, Roland knew that they died from the shock wave of the explosion.
The only survivor is the gray rabbit thirty steps away. Blood is oozing from its thin ear walls. When it sees someone approaching, it no longer struggles, as if the loud noise just took away its soul.
Carter swallowed his saliva, and his buzzing ears gradually returned to normal. At this moment, he understood what the prince meant by "not intending to scare them away". Is this really improved by snow powder? Alchemists are afraid to surpass astrologers with just this achievement.
Iron Axe's look at Roland changed completely. "Your Highness, if the militia can have such a weapon, Border Town will no longer be afraid of the threat of demonic beasts. I wonder if it can be mass-produced?"
Roland shrugged and said, "Probably not. When the Month of Demons arrives, it will probably only be enough to make twenty or thirty." The main key is saltpeter . In this era, the nitrate production method is still very primitive, relying on pouring lime mixture into human and animal feces and urine to collect precipitated potassium nitrate crystals. Except for the alchemy workshop and the upper nobility, there are almost no other uses, so there are not many such refineries, and if they are all used to make explosives, they will soon be exhausted.
As a killer weapon, this weapon must be used with firearms and crossbows.
