Even though there was an incident in which Wu Detao attempted to molest Xing and the others, the fierce counterattack made Prince Wu miserable and did not dampen the good mood of Yang and the others in enrolling. In Yang's memory, similar college admissions on Earth are an extremely exciting event for every student, marking the beginning of a colorful period of youth away from their parents, as they grow up and become adults. They are now standing in front of the new student registration office, only to find that there are already several long queues waiting in front of them to register. Every year, Miner School recruits students from all over the mainland. Except for the well-connected junior students like Yang and others, most of them are poor students from poor families who want to be admitted to the school with full board and lodging. For this reason, some of them came here a month or two early to work and wait, and waited overnight at the entrance of the admissions office. Yang and the others were still running to watch the float parade in the middle, so they naturally fell behind the queue. Yang was not in a hurry and looked at the famous scene at the school gate with great interest, which was a three-dimensional sand table of the entire school simulated using illusion magic. The lifelike floating towers above were the most dazzling. Like the Earth, the latest achievement of continental magic was also the first to be reflected in the military. The three-dimensional sand table in front of you is the three-dimensional map technology from the military. The sand pan has been around since ancient times. It was first made of sand or wax to shape the mountainous landforms, allowing commanders to make timely and accurate battlefield judgments. The three-dimensional sand table generated by illusion can allow the commander to change the terrain at any time based on intelligence, and can also zoom in and out of the specific terrain. This is unmatched by ordinary sand tables. Once launched, it quickly became popular among the armies of various countries in the mainland. It¡¯s just that in the past, using illusions to generate a three-dimensional sandbox required a large amount of expensive magic materials, and only the military was able to use it on a large scale. Later, the most important energy provider, the Fahe Mine Vein, appeared, which greatly reduced the cost of this three-dimensional sand table. Many private companies took a fancy to this technology, which can specifically display the appearance of products without having to worry about being robbed or stolen. It soon became popular across the continent. From the three-dimensional sand table, the long-distance power projection of the strong net is derived from the three-dimensional sand table, and the Dandelion Chamber of Commerce¡¯s magic curtain three-dimensional theater and other technologies are indispensable for many important occasions. This kind of display device is indispensable. However, despite the reduction in cost, maintaining a three-dimensional sand table for a long time still requires a lot of money. Therefore, this kind of sand table is generally only seen in royal families, shopping malls, large entertainment venues and schools. As the birthplace of the illusion three-dimensional sand table, this three-dimensional sand table that can display the urban landscape environment of the entire school in real time has been standing at the entrance of Mineer School all year round, becoming a must-see attraction for audiences from all over the world. This three-dimensional sand table is extremely finely made, with mountains, rivers, flowers, birds, fish and insects all distinguishable inside. It¡¯s just for a layman to see the excitement, but for an expert to see the doorway, the focus of Yang¡¯s attention is not on other things in it, but on the floating seats above the Academy City. The spell towers with different shapes reminded him of a famous computer tower defense game on Earth. The tower defense game is a game that builds war towers with different attack effects on the places where enemies must pass, and then waits for waves of enemies to enter the attack range and wipe them out. It is very popular among the public. However, games are not reality. The biggest problem with this tactic is that it assumes that the enemy will not attack the tower. Even in the magic world of the Nine Realms, it is estimated that no enemy will stupidly allow the tower to attack without fighting back, and will never tear these down. Before reaching the tower, he hurried to die. It¡¯s just that the mages here are very smart and actually built a spell tower that can hang high in the sky. In this way, I can hit you, but you can¡¯t hit me, forming a real tower defense tactic. The spell tower comes from the magic tower. In ancient times, due to geographical restrictions, magicians rarely traveled far and spent most of their time meditating to improve their levels and pondering various new magics. Magicians hate being disturbed by others when they meditate and conduct magic experiments. Therefore, it has become a required course for every magician to build a magic tower that is independent and free from harassment by outsiders. If the magician's strength reaches a certain level, he can open up his own independent space and move the magic tower into it, which makes him feel free and at ease. Each magic tower embodies the material and spiritual wealth of the magician's life, and the location of the magic tower is generally in a place with strong vitality. The magic tower itself is made of solid material and is also engraved with various magic arrays to enhance abilities. Not only The defense is super strong, and it can also greatly improve the magician's various abilities. The magician who stays in the magic tower can easily kill a team of hundreds of people with the support of sufficient magic power, and can even cast spells beyond the level to fight against opponents whose level is much higher than themselves. A magician staying in a magic tower is like being covered with a thick layer of turtle shell, making him invincible. This advantage is quickly favored by other magicians, who plagiarize and create their own inventions. Even martial artists who never like to defend themselves have the custom of building a tower forest after their death. It can be regarded as an alternative magic tower. Where there is defense, there is offense. Spell towers are indeed easy to defend and difficult to attack, but their fatal weakness is quickly exposed. That is, they are all built on the ground. The tower itself is difficult to break. You can find a way on the foundation. If you don't attack the spell tower head-on, then dig it.To attack, hollow it out or use the earth element to create a large-scale mudslide or meteor shower to knock down the magic tower. Of course, the fastest way is to use large siege equipment. No magic tower can last long. Even the long linear city wall cannot stop the onslaught of siege equipment. The magic tower only has one point. Due to its difficulty, the magic tower often ends up in despair when faced with the onslaught of dozens of trebuchets or siege crossbows. The spell tower was saved until the alchemists dug out a technology from the pile of old papers, which was to use the Goblin Empire's floating city technology to make the spell tower rise into the air. Legend has it that when the Goblin Empire was at its most powerful, there were nearly a hundred floating cities floating in the sky of the empire. These cities could drift everywhere, and the high-altitude cities were giant aerial fortresses. If a small stone is thrown from a high altitude, the acceleration of gravity can cause it to penetrate the steel plate. What's more, the floating city is covered with magic cannons, trebuchets and other large war machines. The arrows and flying stones fired are no less powerful after landing. The large-caliber artillery on the Star Chariot exploded. Such a floating city could suppress rebellions in a large area, which was the reason why the Goblin Empire almost conquered the mainland and became the mainstay of the resistance against the demons in the early stages of the First Demon War. It¡¯s just that the records of the core machinery of the floating city have long been incomplete and lost, and the energy used is the Philosopher¡¯s Stone, which is expressly prohibited by the mainland. Several generations of alchemists have spent countless efforts and material improvements to barely allow several floating islands to lift into the air. However, the huge amount of energy and the fact that it requires a lot of manpower to maintain make it impossible to regain its former glory. These floating islands have fallen into the hands of several major powers and professional unions in the mainland, and only they can provide them. Increase the consumption of the floating city. But repairing the floating island also brought a benefit. The alchemists got inspiration from it, so a new generation of spell towers that could lift into the air and move slowly was born. This kind of spell tower can rise to high altitudes that most siege weapons and earth spells cannot reach. Since there is no earth vein support, it can only absorb the vitality of the sky. The spell tower itself must adapt to the needs of lifting into the air and cannot use materials that are too heavy. The defense from the spell tower fixed on the ground is obviously much weaker. However, compared to the ground spell tower that can only be used as a fixed target, the floating tower has many advantages. The power of attacks from a high position is greatly increased, and it can also avoid ground attacks. The only ones that can cause damage to it are flying spells and air forces. However, in In the three-dimensional space of the sky, the magic tower that moves while fighting can challenge the giant dragon. Only the flying speed is a bit slow, and it is regarded as a perfect defensive weapon by various countries. The emergence of floating towers allowed the military of various countries to quickly develop a set of tactical floating towers for fighting around them. Although due to speed and materials, floating towers cannot be used as offensive weapons for large numbers of battles on the front line, but as a defensive weapon for protecting key areas. Defensive weapons are extremely effective. Nowadays, floating towers can be seen everywhere in the capitals of several powerful countries. As an important town of alchemy, magicians from various departments in Minier School are competing to build their own floating towers. There will be a dense projection of a large floating tower. Yang Chulue estimated the number of floating towers and was really shocked. Compared with the number of floating towers he had seen over the capitals of other countries on the mainland, if he were to play a tower defense game in a war, the attacking side would probably need It took a million troops to barely get close to this place, and this still did not include the effect of "Twilight of the Gods". Miner City is indeed a city that does not need city walls for defense! "When I designed Scientific Alchemy No. 1, I also had the idea of ??letting it fly. Now that its internal independent space is perfect, it should be some kind of magic tower. I wonder if I can make it fly after learning alchemy here. "Build your own floating magic tower?" Seeing the steam locomotive and the floating tower with his own eyes, Yang gained a deeper understanding of the profoundness of alchemy. While dreaming about making the star chariot float, he became more determined to learn more. Alchemical determination. There are more and more freshmen queuing up to register at the gate of Mineer School. Even students like Yang and others who rely on Pu's connections to get in without taking the exam still have to queue up to enroll. There are huge crowds of people on the three floors in front of the new student registration office and on the third floor outside. If the police had not set up a long cordon, I am afraid that the chaotic scene of the float parade would still happen. At this moment, the clowns who originally thought to be statues on the balconies at the school gate suddenly moved, causing cheers from around them. Many people in the crowd gathered around the clowns, which reduced the pressure of the freshmen lining up a lot. , but the freshmen at the front all looked uneasy. Yang was very interested in this and asked the tour guide around him to find out that those clowns were some kind of magic puppets. It was said that they came from the most mysterious temple of destiny among the twelve major gods. At that time, the president of the professional union, Trang Zaha, personally They were given to the school. They are mysterious because no one has maintained them in the past hundred years. They still act as usual and are lively. Before new students enter the school every year, they will allocate their grades based on the students' personalities and hobbies, especially their predictions of their fate. Academy, legend has it that it is very efficacious, and over time it has become a very popular show at the Winter Festival.
