The experimental factory is located in the north of the first army barracks. It is the most confidential place on the river. The degree of security is only lower than that of Lingfeng fort.


    Many things that only exist in Arthur''s mind will be experimented and improved here until they finally become a reality.


    Like Warcraft bow, black powder.


    The factory covers a vast area, surrounded by fences and stone walls. There are guards inside and outside, patrolling from time to time. At the beginning of construction, it was told that it was a horse farm and warehouse.


    At the gate, Arthur and his party turned over and dismounted. After verifying their identity, the soldiers in charge of their duties sent people to report, and ordered people to lift the barricade and let Arthur and others in.


    The horses were taken to the real stables. Before the party reached the gate of No. 1 factory, the guard captain Badri and factory director Walter hurried to the factory under the leadership of two soldiers.


    "My Lord."


    "Your Excellency."


    They called.


    Badri was once a guard captain of Lingfeng castle. He was tall, with a thick face, a black leather armor and a Silver Knight''s broadsword around his waist.


    Factory director Walter is a thin middle-aged man. He used to be a writer in the town. At least he has been from Shanghe town since his grandfather.


    During the recruitment a few months ago, Gustav first remembered this rare literate guy. At first, he was appointed to the foreign trade bureau, but later, with the arrival of the bachelors, he was transferred to the experimental factory.


    Arthur smiled and nodded at them. The factory director Walter touched Arthur''s short hair with a restrained and excited look.


    Looking at him, Arthur asked, "are you ready for the test explosion?"


    "Yes, sir!" he replied quickly, "everything is ready. The location is in the open space north of the factory. You can start the test explosion at any time. Shall we go now?"


    Seeing that he spoke with uncontrollable excitement and tension, Arthur smiled and said, "well, first go and see the effect of the test explosion, and then we''ll walk around the factory."


    "Yes, yes."


    Under the guidance of director Walter, Arthur and others walked to the North explosion test site. During this period, they also crossed a river originating from Qingfeng mountain and flowing through the workshop.


    The explosion test site was actually an open space. When Arthur arrived, he saw a lot of bound scarecrows lined up in front of him.


    There are seven or eight scarecrows in a circle, ranging in size. There are five places. The scarecrow in the last place is still wearing old armor.


    Looking at the setting and spacing of these scarecrows, Arthur nodded with satisfaction. The bodyguards beside them were full of puzzlement and curiosity.


    "It''s about a hundred meters here," said Arthur. "Let''s start. I hope you won''t let us down."


    "Count, I promise I won''t let you down!" said Walter excitedly. Then he took out a small red flag and solemnly waved it to a knight holding a torch in front.


    Seeing the sign, the knight with a torch took a few steps forward, lit the lead on the ground, immediately ran back and hid behind a shelter built by a wall.


    Arthur had clearly informed him of these operations, so he was not very curious. Instead, he was the Castle Knight who followed him. When he saw that the guy opposite just touched the ground with a torch, he hid behind the stone wall like a honeycomb, which seemed very puzzled one by one.


    The knights had no time to think about whether there was a honeycomb in the ground. At the moment when the lead was lit, the eyes of the people were tightly grasped by the accumulated fire and rising black smoke.


    "Please cover your ears, my Lord."


    The fire rushed into the circle surrounded by the grass man. Walter on the side immediately reminded him, and took the lead in raising his hands and making a demonstration.


    With his fingers together, Arthur covered his ears with his hands and looked at the puzzled Knights around him with a bad smile.


    "Boom!!"


    There was a thunderous roar, and the flash of fire lit up rolling black smoke. Unknown knights, like frightened horses, subconsciously bent down and took swords one by one to defend the enemy.


    This is not simple black powder!


    There is no doubt that black powder is an epoch-making invention. However, if it is used for explosion, the power of pure black powder is relatively limited. Unless it is detonated at close range, it can not form effective killing at all.


    The explosion just now was Arthur''s soil nitroglycerin explosive mixed with castor oil on the basis of black gunpowder.


    "Big, my lord..."


    Looking at the black smoke rising in front of him, a calm and cold Thorne couldn''t help a look of surprise on his face.


    "Go and have a look!"


    Arthur stepped forward. When a group of people came to the explosion point, they saw that most of the Scarecrows originally set up were thrown away seven or eight meters away. The only Scarecrow was also obliquely inserted into the ground at the moment, burning a fire, completely without human appearance.


    Looking at the straws scattered on the ground and the big pit more than one meter in front of them, everyone looked shocked.


    Even Walter and goodry, who had explosion experience, were also frightened by the huge noise just now.


    In the past, they used only a small amount of explosives in several test explosions, but today, according to Arthur''s request, they filled ten kilograms of explosives in the cloth bag.


    Ten kilograms of explosives, I didn''t expect the effect to be so terrible!


    Just imagine, if those scarecrows were them, they must be bloody and flesh blurred now. They can''t die anymore!


    After the shock, the crowd was immediately excited and delighted. Especially the Knights of the castle almost invariably thought of Warcraft!


    "Sir, with this thing, we don''t have to worry about Warcraft anymore!"


    "Yes! As long as this thing is buried outside the fortress, even if it can''t blow up the Warcraft, it can scare them away!"


    "Well, those damn animals should taste our power!"


    ……


    The Knights'' blood was boiling one by one, and the joy on their faces was unspeakable. Even Thorne nodded happily and looked at Arthur respectfully.


    Looking at the excited knights, Arthur joked: "so happy, you were scared like a great enemy just now!"


    Arthur''s words immediately made the Knights laugh, and there was no shame on his face.


    After everyone was happy for a while, Arthur said, "don''t be happy too early. This thing just sounds amazing, but the actual effect is not good."


    Arthur''s words stunned everyone.


    He glanced at the earth pit more than one meter above the ground and stared at him with a serious face. For a moment, he didn''t know whether to agree or disagree - the effect was not good?


    Looking at the crowd, Arthur said, "ten kilograms of explosives are buried here. It is expected that the hole will be at least twice as big as this!"


    Arthur''s statement has fully considered the actual situation.


    The real nitroglycerin explosive is a kind of explosive with great power and high sensitivity. It will explode violently just by shaking gently.


    Although the nitroglycerin explosive he made is a Xibei product, according to the original estimate, the power of ten kilograms of explosive is more than opening a one meter pit.
