Even if Wu Detao attempted to commit crimes against Li Xing and the others in the middle, he was beaten by a fierce counterattack to make Prince Wu suffer, and did not lose much of the good mood of Yang and the others in signing up for school. In Yang's memory, the admission of similar universities on Earth is also a major event that every student is extremely excited about, marking that they stay away from their parents, grow up, and start a colorful youthful period.

They are now standing in front of the registration office for freshmen, and only then do they find that there are several long queues for enrollment. Every year, Minel School enrolls students from all over the mainland. Except for Yang and others who are related to the back students, most of them are poor students from poor families and want to be admitted to the school. For this reason, some of them came here to work and wait a month or two earlier, waiting overnight at the entrance of the admission office. Yang and others were running to watch the float parade in the middle, and naturally fell to the end of the team.

Yang was not in a hurry, and looked at the famous scene at the school gate with interest. It was a three-dimensional sand table simulated by illusion. The lifelike floating towers above were the most dazzling. Like the earth, the latest achievements of mainland spells were also the earliest to be reflected in the military. The three-dimensional sand table in front of him came from the military's three-dimensional map technology.

There have been sand tables in ancient times. At first, sand or wax was used to shape the mountains and rivers, so that the commanders could make timely and accurate judgments on the battlefield. The three-dimensional sand table generated by illusion can allow the commanders to change the terrain at any time according to intelligence, and can also enlarge and reduce the specific terrain. This is incomparable to ordinary sand tables. Once launched, they were quickly popularized into the military forces of various countries in the mainland.

However, in the past, using illusion to generate three-dimensional sand tables required a large amount of expensive spell materials, and only the military could use them on a large scale. Later, the most important energy provider, the nuclear ore vein, appeared, which greatly reduced the cost of this three-dimensional sand table. Many private enterprises took a fancy to this technology to show the appearance of the product in detail without worrying about being stolen, and soon became popular throughout the continent.

The long-distance power projection of the strong net was derived from the three-dimensional sand table, and the magic curtain of the Dandelion Chamber of Commerce and other technologies are indispensable in many important occasions. However, despite the reduced cost, it still costs a lot of money to maintain a three-dimensional sand table for a long time. Therefore, this sand table can only be 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 landform environment of the entire school all year round is always on the gate of the Miner School, which can display the entire school’s urban landscape environment in real time, becoming a tourist attraction that attracts audiences from all over the world.

This three-dimensional sand table is extremely fine, with mountains, rivers, flowers, birds, fish and insects inside, just outsiders watch the excitement, and the experts look at the tricks. Yang's focus is not anything else, but the magic towers with different shapes floating above the academy city, which reminds him of a famous computer tower defense game on earth.

Tower defense game is a game where the enemy has to pass through a war tower with different attack effects, and then wait for waves of enemies to enter the attack range and let them die. It is very popular among the public. However, the game is not realistic. The biggest problem with this tactic is that if the enemy does not attack the tower, even in the magic world of Nine Realms, no enemy will foolishly allow the tower to attack without fighting back. Before pushing down these towers, they will hurried to die.

However, the mages here are very smart and actually built magic towers that can hang high in the sky. This way I can hit you, but you can't hit me, forming a real tower defense tactic. The magic towers come from magic towers. In ancient times, due to geographical restrictions, magicians rarely travel far away. Most of their time spent meditating to improve their levels and pondering various new magic. Magicians meditate and conduct magic experiments are very annoying to others to disturb them. For this reason, building a magic tower that is independent and not harassed by outsiders has become a compulsory course for every magician. 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 is even more free and easy.

Each magic tower condenses the material and spiritual wealth of the magician's life, and the location of the magic tower is generally located in the place where the energy of heaven and earth is strong. The magic tower itself is made of solid materials and is also engraved with various magic arrays that enhance abilities. Not only does it have super strong defense, it can also greatly improve the magician's own abilities. With sufficient magic power support, the magician can easily kill hundreds of people, and even cast spells above the level, and fight against opponents with much higher realm than themselves.

A magician, a magician stayed in the magic tower, was like wearing a thick turtle shell, standing invincible. This benefit was quickly favored by mages of other schools, and he copied it and created his own magic towers. Even martial artists who have never liked defense have the custom of cultivating their tombs into Tallins after death, which is also considered an alternative magic tower.

There is defense and attack. Spell towers are indeed easy to defend and difficult to attack, but their fatal weaknesses are quickly exposed, that is, they are all built on the ground, and the tower itself is difficult to break, so you can find a way on the foundation. If you don’t attack the spell tower head-on, then dig the tunnel, hollow it out, or use soil to create a large-scale mudslide or meteor shower to knock down the magic tower. Of course, the fastest thing is to use large-scale siege equipment to siege, and no spell tower can support it for long. The long and linear city walls cannot stop the attack of siege equipment. There is only one point in the spell tower. Because it is difficult, facing the attack of dozens of catapults or siege crossbows, the spell tower often ends with a bitter end.

The magic tower was not saved until the alchemists found a technique from the old paper pile, that is, the magic tower was used to lift the magic tower into the air. Legend has it that when the Goblin Empire was at its peak, nearly a hundred floating cities were floating in the sky of the empire. These cities that could drift everywhere, and the high above were huge sky fortresses.

Throwing a small stone from the sky can make it penetrate steel plates even with gravity acceleration. What's more, the floating city is covered with large war machines such as magic cannons, trenchers, etc. The arrow flying stones fired after landing are no less powerful than the explosion of large-caliber artillery on the Star Warrior. Such a floating city can suppress rebellions in a huge area. It was the confidence that the goblin empire almost conquered the continent and became the mainstay of the resistance to the demon race in the early stages of the First Demon-Subduing War.

However, the records of the core machinery of the floating city have long been lost, and the energy used is the Sage Stone that the mainland explicitly prohibits. Generations of alchemists have spent so much energy and material improvements to barely let several floating islands take off. However, the huge energy and the fact that it requires a large number of manpower to maintain makes it impossible to recreate its majesty as it was back then. These floating islands are in the hands of several powerful countries and professional unions on the mainland, and only they can afford the consumption of the floating city.

However, repairing the floating island also brings an advantage. Alchemists get inspiration from it, so a new generation of magic towers that can take off and move slowly was born. This kind of magic tower can rise to a height that most siege weapons and earth-type magic can't reach. Since there is no support from the earth veins, it can only absorb the energy of the sky. The magic tower itself needs to adapt to the needs of the lifting, and cannot use too heavy materials. It is obviously much weaker than the magic tower fixed on the surface to defend.

However, compared to the ground spell tower that can only be used as a fixed target, the floating tower has too many advantages. Its condescending attack power has greatly increased and it can avoid ground attacks. The only ones that can cause damage to it are flight spells and air force. However, in the three-dimensional space of the sky, the magic tower that moves while fighting can challenge the dragon, and the flight speed is only a little slower, and is regarded as a very perfect defensive weapon by various countries.

The emergence of the floating tower has quickly developed a set of tactical floating tactics to fight around it. Although due to speed and materials, the floating tower cannot be used as a large number of offensive weapons to fight on the front line, it is extremely effective as a defensive weapon to protect the key areas. Now, floating towers can be seen everywhere in the capitals of several powerful countries. As an alchemy center, the magicians of various departments in the Miner School are competing to build their own floating towers, and only before Yang's eyes will the projection of a large number of floating towers appear.

Yang Chu slightly estimated the number of floating towers, and was really shocked. Compared with the number of floating towers he had seen above the capitals of other countries in the mainland, if he really played tower defense games in war, he was afraid that one side of the attack would need a million troops to barely get close to this place. This did not add the effect of "Dungeon of the Gods". The City of Miner is indeed a city that does not require city walls to defend!

"When I designed the Science Alchemy 1, I also had the idea of ​​letting it fly. Now its internal independent space is very complete. It should be a certain kind of magic tower. I wonder if I can turn it into my own floating magic tower after learning alchemy here?" Seeing the steam locomotive and floating tower with my own eyes, Yang had a deeper understanding of the vastness of alchemy. While dreaming of letting the star chariot float in the air, he strengthened his determination to learn more alchemy.

There are more and more freshmen queuing at the gate of Miner School. Even students like Yang and others who rely on Pu’s relationship to enroll without exams must be honest. There are crowds of people in the middle and three floors in front of the registration office. If the guard team had not set up a long cordon, the chaotic scene of the float parade would have been staged. At this moment, the clowns at the gate of the school, who originally thought they were statues suddenly moved, attracting cheers around. Many people in the crowd surrounded the clowns, reducing the pressure on the freshmen queuing a lot, but the freshmen at the front all showed a look of uneasiness.

Yang was very interested in this. When asked the tour guide around him, he realized that the clowns were some kind of magic puppets. It is said that they came from the most mysterious temple of fate among the twelve main gods. At that time, the president of the professional union, Trunzaha, personally gave them to the school. They said that they were mysterious because no one had repaired them for nearly a hundred years, and they still acted as usual and jumped around. Every year before freshmen entered the school, they would assign the colleges to their students based on their personality and hobbies, especially their predictions of their destiny. The legend is very effective and over time it became a very popular show at the Winter Festival.
