As early as the beginning of his reign in the northern countries, Caesar had prepared for a rainy day and made a series of follow-up urban plans, such as assembly line factories, card workshops and even the new weapons research institute, which were located in the suburbs and built around the king''s city, so that they could be concentrated for effective observation. With the help of the caster, the research institute built on earth brick and rock was very fast, And it will not affect the construction progress of other works of the Empire.


    The power of money is boundless. In just half a month, Caesar ordered the caravan to purchase a large amount of saltpeter from zedi kingdom in the southwest. Now they are all transported to a nearby warehouse for storage. When they are used, they are ground and weighed by human servants and sent to the Weapon Research Institute of Honglian goblin in batches. Of course, the same is true for charcoal and sulfur, However, these two materials do not need to be imported and can be obtained locally in Beidi.


    The handling and mixing of the three raw materials are completed by the monsters of the black wing clan, and other people are not exposed to this stage. The benefits of this operation can minimize the risk of disclosure, but it is only reduced. If it really attracts the attention of the gods, the black dragon will not hide it for long. The magic power of the empire is far from that step.


    According to the chemical rules in Caesar''s memory, the best composition ratio of sulfur, charcoal and saltpeter should be 1:1.5:7.5. However, this is only a formula derived based on the material rules of the earth. Whether there is a better proportioning scheme in ayladia needs further experiments and exploration.


    Caesar was very interested in the development of gunpowder. This guy personally came and sat outside the new weapons research institute, watching the wild boar people weigh 20 pounds from the prepared black gunpowder and slowly put them on a huge parchment.


    According to the requirements of Heilong, these gunpowder have been subjected to a series of fine treatments such as crushing, soaking, pressing, drying and screening. Now they are presented as particles of uniform size, which are extremely dangerous, flammable and explosive in theory.


    In order to prevent accidents, the whole production process is independent, and the assembly line production mode has not been introduced into the manufacture of black powder.


    The process of pouring and weighing gunpowder was repeated four times, and the weight gradually increased. The last one weighed a hundred pounds. When everything was finished, Caesar helped the wild boar people fold the sheep''s skins layer by layer, and then watched them tie them tightly with ropes.


    "That''s all?"


    Luna opened her eyes wide. Is this what Caesar said? The black dragon didn''t hide it from her, so the little guy knew the whole process of making gunpowder, but how can gunpowder without magic support be turned into gunpowder?


    Rely solely on sound to intimidate the enemy?


    After careful consideration, the little guy found that it was feasible. Although she didn''t know how others were, she would still be frightened if the voice was loud enough.


    "Hum."


    The big black dragon shook his head and ignored her. He hummed twice and stuffed four portions of gunpowder into his claws: "you''ll know later."


    More than 30 miles south of the kaki border, the vast no man''s land in the tuhala desert is the test explosion area designated by Caesar this time. Some red lotus goblins and troops have been waiting here for a long time.


    Hogg also came. As the most powerful supporter of the Black Dragon Emperor, Caesar felt it necessary to let Hogg know about similar things, so that when he fell asleep again in the future, Hogg, the temporary ruler, could use these new weapons more reasonably.


    According to the order of his majesty, the army of the black wing clan has already set up a long cordon here, and there are flying dragons and men and horses patrolling near the center to prevent all outsiders from approaching.


    Caesar took Luna around in the air and checked it. After confirming that there were no mistakes, he nodded and landed roughly in a very elegant way: "are you ready?"


    "At your command, your majesty."


    The boar man came with an army. They guarded several huge mobile cages. Luna noticed that there were snake owls, claw fearing beasts and rock giants in it. In addition, there was an adult Mamen lizard in the rear.


    Another Mamen lizard


    Luna wiped her forehead. Anyway, as long as it wasn''t good, there were Mamen lizards. In addition, there were some prisoners from the dark area. The large-scale war under the royal court continued. However, since Caesar appeared, the monsters of the underground clan fled back to the underground cave one after another.


    Caesar didn''t want to chase these guys, so after recruiting the Tauren clan, he handed it over to the "dark twin" with a weak sense of existence, and sent Garon and blackhia to integrate the power of this dark area.


    The two little dragons are very happy about this. They have been with Caesar for so long. They have known that their brother developed and thrived savagely from a closed dark area, which gives them great expectations and vision and tries to pursue Caesar''s track.


    After accepting the transformation and excluding the divine influence of Tiamat in the body, Caesar can still give them some trust. The two dragons are not stupid... At least Garon is not stupid. They should not do anything to ask for trouble.


    "Very good. Bring the weakest one first."


    Waiting for everything to be ready, Caesar took the minimum dose of the bag to Hogg and asked the Jackal to make a small hole in the sheep''s skin bag with his sharp claw to leak the black gunpowder.


    Even the smallest bag has a full 20 pounds. If it is placed on the earth, it is an extremely terrible dangerous goods, but the world of Aladia can not be measured by common sense. The larger the equivalent, the better.


    The black dragon ordered everyone to step back and keep a safe distance. He didn''t move and stared at the ferocious snake owl in the cage with little Luna.


    The large-scale production and trial explosion of gunpowder is not Caesar''s reckless act on a whim. Long before that, under his guidance, the red lotus goblin had done a small amount of ignition test. Facts have proved that it is feasible according to the formula. Although it is not known whether there is a better proportioning scheme in ayladia, at least for now, there is no problem with such manufacturing.


    Therefore, Caesar is not worried about the results, but he still has emotional fluctuations - compared with the improvement of his own strength, this is a completely new feeling. From now on, the rolling wheel of history or the turning point in the future, and the thermal weapons purely following the laws of matter will embark on this stage dominated by supernatural forces.


    What kind of spark will appear after the prelude is opened is unknown, but Caesar tangrian and a black dragon will be the unveiling of this remarkable beginning.


    After waiting for everything to be ready, the black dragon squeezed out a flame jet from his teeth and ignited the gunpowder.
