The most worrying thing still happened.


    Lux''s heart suddenly twitched.


    She didn''t want to see Su Chen and her brother fighting against each other, guarding each other like thieves, they should be honest like friends... and brother Jiawen...


    Maybe it''s because I''ve always thought of things too simply, in this troubled world...


    Lux sighed bitterly.


    How many secrets does her fiancé still hide?


    Before, she felt that Su Chen''s dual cultivation of magic and martial arts was incredible. After all, both magic and martial arts are worth immersing in for a lifetime.


    Now, he has shown extraordinary alchemy again!


    Such a terrible weapon as gunpowder was made!


    This thing is much more terrifying than those toners in the alchemy workshop...


    How on earth did he do it?


    Lacus was puzzled.


    "Go."


    "Try not to be discovered by him."


    Galen waved his hand.


    philip. Church and Gore were ordered to resign and went to arrange to monitor Su Chen.


    "Um?"


    Sudden.


    Galen faintly sensed the direction of the tall buildings of the main castle, and a pair of eyes were watching him.


    Turn around sharply!


    He stared at the window of Su Chen''s bedroom!


    But I didn''t see anyone standing there.


    "Is it an illusion?"


    Galen frowned and withdrew his gaze.


    Ashe leaned against the window sill. The chest rises and falls.


    "It''s dangerous, I was almost discovered..."


    "horrible!"


    "It''s really scary!"


    "Is that really me... the weapon I participated in making?"


    Ashe was stunned for a moment.


    It would not be an exaggeration to say that the explosion just now was devastating!


    Even from hundreds of meters away, she could feel the extremely terrifying destructive power from the trembling bedroom... It was as if the doomsday had come and destroyed everything!


    A few minutes later.


    Su Chen is back.


    Ashe stared at him for a long time, her cherry lips parted slightly, "Then... what is it?"


    "gunpowder."


    "Improved from the toner in the alchemy workshop."


    Su Chen was working at his desk. He took out a ruler and pen, buried himself in drawing something on a piece of white paper, raised his head and smiled, "The saltpeter you extracted from the nitrate soil is an important raw material."


    "so……"


    Ashe pondered for a while, "Aren''t you afraid of being arrested if you expose the gunpowder? I mean, those nobles who are keen on war may find a way to ask you about the production method of gunpowder."


    "I am the Marquis of Lucifer personally appointed by His Majesty."


    "Who dares to force me?"


    Su Chen shook his head with a smile, "Besides, with my strength, two holy rank might not be able to keep me."


    "oh."


    Seeing that he was so calm, Ashe didn''t say anything.


    Brother Su must have thought more than himself.


    "What are you drawing?"


    Seeing that Su Chen was so serious, Ai Xi couldn''t help walking over curiously, and leaned to his ear, and found a long tube-shaped structural diagram on the white paper.


    "This is called a fire door gun."


    "Combined with lead pellets, it can concentrate the power of gunpowder and accurately destroy the target."


    "the most important is……"


    Su Chen said while drawing: "It is very simple to operate, even an ordinary peasant woman. After a few hours of training, it can easily kill a well-trained knight in armor."


    "ah?!"


    Ashe froze.


    An ordinary peasant woman killed a heavy armored knight?


    How is this possible!


    With her intelligence, she really couldn''t understand it, it was simply a fantasy.


    "Perhaps Big Brother Su can really create a miracle."


    Ash was silent.


    Su Chen also stopped talking and concentrated on drawing.


    In the library of Chuzhou City, he once read some design materials of medieval Ouzhou guns. Using black powder as the raw material, even the lead pellets shot by the most primitive and garbage Huomen guns can easily penetrate knights. The armor on his body.


    The musket is the simplest musket.


    It has numerous shortcomings.


    When shooting, the barrel emits a lot of smoke. Unable to get shooting feedback.


    There is no rifling, which leads to poor accuracy. Hitting people from 20 meters away is all about luck.


    The failure rate is high. In the Middle Ages when there was no high-precision lathe processing, the barrel structure was purely hand hammered by blacksmiths, and the quality was difficult to guarantee. Misfiring and bombing are often encountered, and the failure rate can reach up to 4%.


    In addition, it is very troublesome to clean the barrel and refill the gunpowder after each shot. A well-trained gunner can shoot three shots a minute is already very good.


    but.


    Even so, the Huomen Spear is still an epoch-making weapon, and its power is far beyond that of a crossbow.


    We often see it in movies. Medieval royal musketeers lined up in gorgeous and colorful costumes when fighting. Stand densely, and move forward fearlessly under the drummer''s horn.


    After entering the shooting range of 3m ~ 6m. They raised their guns and fired at each other.


    Many people sneered at this tactical offensive method of "queuing up and shooting".


    But in fact, the intensive positioning is to ensure accuracy by increasing the shooting density-under an indiscriminate attack, the bullets will be concentrated in one area, causing effective damage to the enemy.


    This is called equipment determines tactics.


    Bullets whizzed past the ears, and the comrades around were killed one by one. Can you still keep the formation in order? This is a great test for the psychological quality of the soldiers.


    The defeated side is often the one whose formation collapses first.


    Line tactics are a test of the psychological endurance of soldiers, and deserters and draft evaders abound.


    And once in the army. The officers will use whips and boring training to turn you into a numb animal that can move forward firmly under the fire of cannons and bullets.


    "The firearm is the most primitive and simple firearm."


    "It only needs to create a qualified barrel, add a wooden butt, and a fire door that communicates with the breech chamber of the gun. You don''t even need a front sight."


    "It''s better to start from the simplest, step by step, it''s impossible to make ak47, m416..."


    While drawing with a ruler and pen, Su Chen was thinking in his mind:


    "The subsequent matchlock guns, flintlock guns, and flash cap guns are not very technically difficult. Then, the primer is more troublesome. It is necessary to get the mercury fulminate primer and produce the needle percussion gun..."


    Ten minutes later.


    The barrel structure diagram of the simplest fire door gun is vivid on the paper.


    The ratio is 1:1, and various instructions are marked on it.


    For example, the barrel steel must be hammered tightly without trachoma and pores, and the inside of the barrel must be polished extremely smooth without any slight protrusions. Any slight deficiency may cause the barrel to explode!


    After drawing the picture, Su Chen told Ai Xi to stay well, and he went to the blacksmith shop in the city.


    But as soon as he went out, he was keenly aware that someone was following him!


    After leaving the gate of the castle, the tracking team changed from one to three...
