As early as the beginning of the building of the cement section, Roland made plans for several subsequent project test rooms. Most of them were built around the north slope mining area and could be effectively concentrated to guard the houses - this kind of bungalow with a brick wall and wooden ceiling was extremely fast, and it did not affect the progress of the city wall construction.

The saltpeter purchased from Liuye Town is transported to nearby warehouses for storage. When it is needed, it is ground and weighed by the servants and sent to the bungalow in batches. The same is true for charcoal and sulfur. The handling and mixing of the three raw materials are all done by people in different groups, which can minimize the risk of leakage.

Roland weighed twenty pounds from the prepared black powder and slowly poured it on a cut sheepskin.

These gunpowders have been soaked, compacted, dried, crushed, screened, etc., and have become evenly granular, with excellent combustion performance. In order to prevent accidents caused by collision sparks, no metal utensils were used in the entire production process, and most of them are ceramics or wood products.

After pouring the gunpowder, Roland stacked the sheepskin layer on top of the layers, wrapped it to three layers, and tied it tightly with a rope.

"That's all?" Carter asked. Can this thing be called a weapon? Although it is a modified product of snow powder, who can it be scared by sound alone? It may play a role in dealing with farmers who have never been to the battlefield. Any trained warriors and mercenaries will not take it seriously. However... the chief knight carefully considered it. What Your Highness has done recently seems to be unreasonable, but most of them have amazing effects. If the IQ of the evil beast is similar to that of the wild beasts, perhaps this thing will be unexpectedly effective? For example, a thunderous sound caused them to be frightened and fled, thereby reducing the pressure on the defending team.

Roland stuffed the wrapped gunpowder into Carter's arms, then took a bag of fine grinding powder for inducing the fire, "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 Hidden Forest and the Desperate Mountains is the test explosion area he set out this time.

Iron Axe and several other hunters have been waiting here for a long time. Except for Iron Axe, everyone is a local and the group with the best archery skills. When he heard that His Highness the Prince had a task to them, he immediately couldn't wait to follow Iron Axe.

Now everyone knows that the new lords in Border Town are never stingy with the employment rewards.

According to Roland's instructions, they set up long wooden poles around, tied ropes, and formed a guard circle nearly half a mile. Knight patrols were arranged in the direction close to the city wall to prevent anyone from approaching unexpectedly.

Roland checked around the guard circle and nodded, "Have you brought all the prey?"

"Your Highness, all are here," Iron Axe walked up to drag a cage, and Carter noticed that there were several pheasants and rabbits inside.

"Very good, put them at a distance of five steps, ten steps, fifteen steps, and thirty steps from the center point, and tie one to each wooden stake."

Carter shook his head secretly and stepped forward to suggest, "Your Highness, the animals you chose may not be able to test the results. They are extremely timid and will scatter and run away if there is a slight noise. Even if they can scare them, they may not be able to scare away the evil beasts."

"Scare away the evil beasts?" Roland was slightly stunned, and then reacted, "I didn't plan to scare them away, although the momentum of this thing when it exploded was indeed amazing."

He took the chief knight to the center of the circle, put down the gunpowder bag, and cut a small hole with a dagger to let the gunpowder leak out. Then he took out the leather bag containing gunpowder powder, sprinkled it from the break, and sprinkled it in a direction and retreated.

Today is a windless weather, which is very suitable for this primitive detonation method.

After leaving for nearly a hundred meters, Roland put away his leather bag.

"Okay, just light the fire here," he repeatedly estimated the distance and confirmed it was correct before saying to Carter, "Go and call all the hunters over."

Roland was also a little excited at this moment. He had already done a small 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, thermal weapons would officially take the stage, and he would be written into a milestone in history as the leader.

After everyone gathered, Roland lit the powder.

Carter lay on the ground, looking at Mars that was quickly moving away, feeling a little dissatisfied.

At such a long distance and not placed in the bronze bucket, it is still a question whether the sound of snow powder can reach here. His Royal Highness actually made everyone lie on the ground. However, since the Fourth Prince took the lead in doing this, he couldn't say anything more.

The ground in winter is full of coldness, and you can feel the spreading chill through the chain armor. When Carter moved his body and was about to turn his chest sideways, a shocking sound suddenly rang out-

Because the distance was too close, the explosion and shock waves reached almost at the same time. He felt his ears buzzing and the world suddenly quieted down. The tremor of the earth was fleeting. He raised his head and saw a black cloud slowly rising, and then gravel and mud fell one after another like rain.

Roland was much smaller than the Chief Knight. Even setting off firecrackers would block his ears. He immediately prepared to protect himself after igniting the powder. The explosion point was not like the ones performed in the movie, and it would free up a huge fireball. The fire flashed and a large amount of mud was lifted by the air waves and rushed into the air about ten meters of air. When the dust settled, Roland's only feeling was: this sound was much louder than the firecrackers.

As for the Iron Axe and several other hunters, they were already stunned. Only Iron Axe knew that this trip was to test a new weapon, but they did not expect that the weapon's momentum was so amazing.

I'm afraid only the Thunder of Heavenly Punishment can be compared with it!

Roland stood up and took everyone back to the explosion site. There was a pit half a meter deep on the ground. The rabbit closest to the explosion center was no longer visible, leaving only a short piece of wooden stakes on the ground.

He examined the other animals one by one, and the pheasants placed in ten and fifteen steps were lying motionless on the ground, apparently dead, and although there was no obvious trauma, Roland knew they died from the shock waves of the explosion.

The only survivor is the gray rabbit thirty steps (about 15 meters) away. Blood oozed from its thin ear walls. When he saw someone approaching, he no longer struggled, as if the loud noise had just taken away its soul.

Carter swallowed, and his ears gradually returned to normal with constant buzzing sounds. Only then did he understand what His Highness said, "I didn't plan to scare them away." Is this really improved by snow powder? The alchemist is afraid that he will be far superior to the astrologers with this result alone.

The Iron Axe looked at Roland completely changed, "Your Highness, if the militia could have such a weapon, the border town would no longer be afraid of the threat of evil beasts. I wonder if it could be made in large quantities?"

Roland spread his hands and said, "It probably won't work. When the Demon Month comes, it's probably only enough to make twenty or thirty." The main key is saltpeter. In this era, the method of making nitrate is still very primitive. It relies on pouring lime mixture into the urine circle of human and animal manure to collect the precipitated potassium nitrate crystals. Except for the alchemy workshop and the upper nobles who have demand, there are almost no other uses, so there are not many such refining sites, and if they are all used as explosives, they will be consumed soon.
