Since I did not explain the Magic Crystal Cannon and the Magic Dynamic Cannon clearly in my previous article, which caused a lot of questions, I will now explain the two weapons:
Magic Crystal Cannon: A super weapon from another world, made of hollow cylindrical magic crystals, the manufacturing method has been lost. It weighs about 3 tons, has a caliber of about 200MM, and a range of 3 kilometers.
Working principle: Similar to modern laser weapons or other energy attack weapons
Attack method: The magician pushes the energy-gathering magic circle in the magic crystal cannon, using the enormous magic power of the magic crystal itself, plus the gathered external magic power, to generate super strong propulsion force for attack.
Magic Cannon: A combination of magic and technology, closer to modern artillery. The only difference is that the gunpowder used for propulsion and the energy required for explosion have been replaced by magic. Weight 500 kg, caliber 100 mm, range 2 km
Working principle: Use fireball or explosive bomb magic to generate thrust to push the warhead to launch. Then the shell explosion also relies on the magic built into the warhead to attack.
Explanation for not making a larger Magic Cannon (many people think that a larger Magic Cannon could be built to give it a longer range)
The explanation is as follows: Magic is not like gunpowder. If you want gunpowder to produce greater propulsion, you can generally increase the amount of gunpowder to produce greater propulsion, but magic is different. I can't put two magic scrolls in the magic cannon to propel a warhead. Because magic scrolls can only increase multiples, while gunpowder can be freely controlled from 1% to several times. In addition, when detonating, no one can guarantee that the two magic scrolls will be detonated at the same time. The time difference is definitely a problem.
In addition, regarding the logistics of the orc invasion, I will answer as follows (I set the orcs to be a nomadic people).
Fight to support the war. When a troop is preparing to fight to support the war, it only needs to keep moving, robbing, and maintaining victory in the war. In general, it has no logistical worries. For such a troop, as long as it robs a village, then a normal village with 500 people, the looted materials can at least support the food and grass needs of a troop of 10,000 people for more than one month. (All food, all poultry and livestock, and if you are a little more ruthless, even human flesh can be killed and eaten! After all, the book is not a war between the same race)
In addition, because of the lack of information at that time, the villages and civilians in various regions generally had little chance of getting the news and escaping from the occupied areas. . . . . . (To be continued)
