Pure potassium nitrate has no taste.


    Gustav smelled the pungent smell because the maonitrate contained impurities and was not purified.


    "This is not salt, but fertilizer."


    "Fertilizer?" Gustav said. "That''s what''s in those caves? The cave you''re talking about?"


    Seeing Arthur nodding, Gustav picked up and smelled again. This time, the pungent smell was much lighter.


    Looking at Arthur, he asked curiously, "as long as you use this thing, you can make crops grow better? Harvest more food?"


    A few months ago, when Arthur asked him to send someone to look for the nitrate hole, he briefly mentioned the role of the hole nitrate with him, but Gustav stared at the pile of things in front of him. No matter how he looked, he didn''t feel like fertilizer.


    "Practice is the only criterion for testing truth!" said Arthur. "Wait until this wheat harvest, you will know the answer."


    "Hey, I don''t doubt you, my friend!" Gustav said quickly. "It''s just that it''s so beautiful. It''s also fertilizer. Those manure won''t be put on the table. It looks as beautiful as salt!"


    Because of the problem of purification, the salt in this world has a light yellow color and large particles. The salt eaten by serfs and the people even has an obvious bitter taste.


    "He can be more beautiful than salt," Arthur said. "In addition to being used as fertilizer, it can also be used to make gunpowder after purification. Then it will be as white as snow."


    "Gunpowder, what is this?" Gustav asked hurriedly.


    Now he is full of curiosity and expectation about the new things made by his friend.


    Arthur couldn''t help laughing at Gustav''s appearance. This guy probably thought of gold coins again.


    "You fat man, the treasure is in front of you, but you don''t see it. I tell you, if it''s not for the production limit, the nitrate in front of you is not much worse than the wine just now!"


    "It''s just fertilizer," Gustav disagreed.


    In this world, the vast majority of land is in the hands of nobles. For nobles, as long as there is enough food, they don''t care much about the life and death of civilians and serfs.


    Compared with starvation everywhere, as long as they do not threaten their rule, nobles will care more about their enjoyment.


    Arthur knew that the value of cave nitrate was not something that could be explained simply, so he didn''t bother to waste time explaining it.


    "I can''t understand a word or two. Let''s continue talking about gunpowder," he said. "In short, gunpowder is a kind of thing that can burn violently. It can be made into powerful explosives with strong lethality. We can use it to resist Warcraft. You can think of it as a smaller thunder."


    "Thunder!" Gustav thought, not curious. "What do you need me to do? Is it to arrange reliable hands to make gunpowder?"


    "It''s still early!" said Arthur. "The hole nitrate in front of you is only one of the raw materials for making gunpowder. I need you to import sulfur from businessmen!"


    Sulfur is different from nitrate. It generally exists only in places with relatively active geology, such as volcanoes and hot springs.


    There must also be sulfur in Shanghe collar. The reason why Arthur asked Gustav to import from businessmen is that people in the world have mastered the purification and use methods of sulfur, such as using sulfur to prevent insects, dye cloth, dye hair, etc.


    Compared with their own laborious manufacturing, it is much more convenient to buy directly.


    "No problem. How much sulfur do you need? When I get back, I''ll immediately tell the people in the foreign trade bureau to do it." Gustav asked.


    He would not ask why sulfur was needed to make gunpowder. In short, as long as Arthur ordered, he Gustav would do it as quickly as possible.


    "For the time being, we don''t need too much. We buy it from businessmen in several times, and buy a few hundred kilograms at a time. It''s said that we use it to prevent insects."


    "It''s easy!" Gustav said with a relaxed smile. "I''m afraid those guys will be disappointed at this amount."


    Only a few hundred kilograms at a time. With this amount, a businessman can meet their needs.


    ……


    ……


    To the north, ligppus county.


    In a hotel called loregg, which is located beside wilderness Avenue, men were laughing.


    Ligopos county is the territory of the Davidson family, and this hotel called loreg is located in the southeast of the place. As long as it goes all the way south along the Avenue outside the hotel, it is the East.


    Because of its geographical location, most of the guests of this hotel are businessmen and mercenaries.


    It was getting late. In the lobby of the hotel, several circular oil lamps were hung from the wooden beams. Under the oil lamps, dozens of mercenaries and businessmen from the north and East were sitting around more than ten wooden tables.


    The mercenaries never spoke as politely and politely as the bachelor. They drank wheat wine and ate food. They talked loudly about the gossip of women and nobles. When it came to interesting places, they laughed together, knocked the wooden table with their wine cups and signaled to raise their glasses together.


    At this time, a middle-aged mercenary wearing a black cloth coat and a long sword at his waist stood in the center of the hall with a wine cup in his hand. Under the eyes of the people, he told the story of going to the river to lead the war half a month ago.


    "I tell you!" he bent over and shrunk slightly, glancing at the crowd in front of him.


    "Just when those guys in the East thought they would win, a horn suddenly sounded on the mountain! Then, thousands of knights appeared on the hillside, all of them holding javelins. Under the command of the count of Shanghe, those javelins were like arrow rain!"


    With that, the mercenary drank a mouthful of wheat wine, pulled the corners of his mouth and looked at the mercenaries who were listening to him attentively.


    "Then what? What about the people and horses in the East!"


    "Smelly feet, you fucking say it! What happened later?!"


    "Did you dodge them all? None of those javelins hit!"


    ……


    The mercenaries were excited to hear it. When they saw him stop, they were immediately urged by dissatisfaction.


    "Hide? Hey!" smiled contemptuously at the mercenary who said he had escaped, and the mercenary with the nickname smelly feet continued to say, "I tell you, I was lying on the opposite hillside, for a moment, for a moment! Hundreds of people were killed at once when they were chasing the count of Lingfeng castle!"


    "You didn''t see it, but I saw it with my own eyes! I can smell the bloody smell scattered by hundreds of people and horses when I lie on the mountain. The land is dyed red. The blood flows into the river, and the whole river has become a blood river!"


    "The count of Lingfeng Castle rode on his horse. Although he was too far away to see his face clearly, he was at least eight feet tall, holding a huge axe in his hand. When he roared, he turned around and rushed to the people and horses in the East! Under the fighting, even his beard was dyed red! Beside him -"


    "-- hahaha!"


    Just as the knight named smelly feet was talking hard, a burst of laughter suddenly came from the corner of the hall.


    Before smelly foot got angry, a mercenary who was not strong directly mocked: "smelly foot, you are really boasting! The count of Lingfeng castle is clearly a teenager! And he has no beard at all!"
