There are three kinds of wizard towers, the largest of which is the wizard tower built in Zhenbei city. In the era of the arcane Empire, this large wizard tower usually existed as the control center of the floating city, that is, this wizard tower is usually to upgrade into a floating city.

Of course, because by now, the construction technology of floating cities has long disappeared in the dust of history. Perhaps these floating cities still exist in some remote corners of the multiverse. After all, the original war arcane empire was not completely destroyed.

The arcane empire is nominally an empire. In fact, it is a bit like city-state autonomy. Each floating city is an arcane organization. The big arcane in this arcane organization is their leader and decision-maker, responsible for managing the affairs of the floating city. All floating cities are the arcane empire. Of course, the binding force of the empire is not strong.

Usually, floating cities with similar relations will jointly explore the plane. Of course, there is also a single floating city to explore and conquer the plane. At the beginning of the war with the gods, the arcane Empire did not pay attention to it in the early stage, and many people ignored it. By the time the arcane Empire united in the middle stage, they had begun to retreat. Otherwise, the war was expected to be more fierce. It was not certain who would lose and win.

Although there is no way to upgrade this top wizard tower to a floating city, the equipment is still powerful, so usually only those large wizard organizations will build it, and then take this wizard tower as the main tower of the college.

The second kind of wizard tower is about 60 meters high. It is usually the residence of legendary wizards. The cost of this kind of wizard tower is also not low, usually 5 million jinnars. Of course, local tyrants and wizards will spend more. In this kind of wizard tower, there are usually magic image legions to guard. A wizard tower is equivalent to an army.

The last kind of wizard tower is the small wizard tower. It is usually a caster at the level of Archmage and costs millions of dinars. However, although it is much smaller, although the sparrow is small and has all kinds of internal organs, there are still some things that should be. This kind of wizard tower is also the largest among the major wizard organizations.

Hearing that Phyllis said to build this kind of wizard tower, Suellen thought about it and agreed. After all, in the future, there will be wizards sitting in the city of San ferto all year round, and a wizard tower can meet their experimental needs.

After Suellen rested in San ferto for a few days, Hathaway also completed the construction of the transmission array. The transmission array cost more than one million ginals, which can connect the north city of the town and can transmit up to 30 people at a time. If the element pool is full of energy, it can be transmitted about 60 times.

Of course, if it is transmitted from Zhenbei city to here, the number of times will be more. After all, the element pool in Zhenbei city has several times more energy than the element pool here.

After the construction of the transmission array, the Wizards of the emerald tower also invited Suellen and Hathaway to exchange spells. Of course, Hathaway is the one they want to invite. After all, a legendary witch has too much knowledge. Su Lun was still very curious about the emerald tower, so after receiving the invitation, he took several barbarian predators and Hathaway to the emerald tower for communication.

The emerald tower is located in the southwest of San ferto city and on the thorny wasteland, about 500 kilometers away from San ferto city. The thorny wasteland can be said to be sparsely populated. In ancient times, the thorny wasteland was also a battlefield. The aftermath of the battle caused the barren land here, but the element energy here is very rich, and many demonized creatures live in the wild, There are also some plants that mutate because of spell radiation.

For ordinary people, this land is a dangerous place. Entering it is ten dead and no life, but for wizards, it is a treasure land. The elements here are full of energy, suitable for wizards to meditate, and there are many mutated plants, which are also suitable for planting all kinds of magical plants. Because of the magic energy radiation, many demonized animals live and provide them with a lot of magic materials and experiments.

......

"I'll make a flying prop in the future." Su Lun looked at the white clouds passing through the window and the mountains under his feet. He was very envious of the airship.

He is now riding in the transport airship of the emerald tower, which is more than 100 meters long. With a width of more than 40 meters and five floors, there are more than 200 large and small rooms, which can fly in the air at a speed of 300 kilometers per hour. According to the working principle of this airship, Hathaway speculates that it should be a floating array, and the energy is energy crystal. This crystal is made of magic crystal after special treatment.

It can store a large amount of element energy and release it slowly like a battery. After the energy is exhausted, it can be used again as long as it is sent to the element pool for recharging. It can be said to be very convenient. Although the airship uses wood materials, all of them have been hardened. The hardness is not inferior to that of steel, but the weight is much lighter than that of steel. This is one of the reasons why airships can be built so large.

As for the combat capability of the airship, because they didn't show it, Su Lun didn't know, but it should not be weak. There is plenty of food on the airship. There is a restaurant and even an entertainment room on the airship to kill time.

Such an airship is far superior in all aspects except that its speed is not comparable to that of previous aircraft. Although Tianma can gallop in the air, this airship is a very good tool for transporting troops and materials. Even if it is not used in the military, it is much more comfortable to sit in an airship than riding Tianma.

When he came to the thorn wasteland, Su Lun found that the environment here was very bad. There were many violent wolves in groups on the wasteland, Saber Toothed tigers, and even some traces of Velociraptors. Giant elephants, wild cattle, stone clawed animals and so on, with a high degree of danger.

It took almost two hours by airship. Sulun and his party came to the emerald tower on the thorny wasteland. It is said to be the emerald tower. In fact, it is almost a city here. After passing through the illusion barrier used by wizards to hide, a town appears in front of us. The most striking one is the large wizard tower 100 meters high in the center of the city.

A large amount of obsidian was used to build the city walls around the city, and a winding moat flowed. In addition to the tall wizard tower, there are 67 wizard towers of more than 60 meters in the city. The buildings built around the wizard tower are the same. The more you go outside, the more messy the buildings will be. The outermost area should be the area where ordinary people live.

These ordinary people are basically servants of wizards, planting food and providing all kinds of materials for wizards. Of course, if their children and grandchildren have wizard qualifications, they will also be paid by the emerald tower.

"This is our city, the city of emerald!"

"This city has a population of 80000 and has a history of 2000 years. It is a city built by the first generation of tower owners of our emerald tower, and then continuously expanded in the following hundreds of years."

"The highest wizard tower in the city is the emerald tower, and it is also the most powerful wizard tower in the whole kingdom of Florence!" Edmund said proudly.

Sulun did not speak. He is really the strongest now, but as long as the north wind tower is built, you will be the second.

As the airship approached, people also saw many stone carvings on the wall, including stone statues and ghosts, and some soldiers with weapons. The whole body is composed of obsidian, which seems to be a kind of structural life.

"There is the greatest building of the emerald tower [Emerald Heart library]."

Edmund said, "this library has hundreds of thousands of books and a lot of valuable knowledge."

"The first floor is free, and everyone can enter and check. The second floor is only accessible to wizards."

"Well, we're coming!"

As Edmund's voice fell, the airship began to slowly reduce its height, and finally the airship stopped in a spacious field.

Su Lun and Hathaway got off the airship with several attendants. They were curious to observe everything here. Around the site, Su Lun saw a lot of Obsidian Statues. In addition to stone ghosts, these statues also had a lot of human statues, which were very similar to the stone ghost statues in the north of the town. They should be combat puppets.

After they got off the airship, Suellen saw some wizards looking here not far away.

"Those are the Wizards of the plastic school, a group of bad tempered guys."

"See those buildings with green leaves? Those are witches who study plant magic. They are good at planting all kinds of magic drugs. Many of them are magic drug masters. Of course, if someone thinks they are weak, they will suffer a great loss."

Then Edmund introduced several other wizard schools, and Suellen was still very interested in these schools.

Led by Edmund, Suellen and his party came to a house.

"This house is where you live, and the conditions are poor. Please forgive me. The hut next to it is the servant in charge of your accommodation. You can tell them if you need anything. If they can't be the master, they will also report it to us."

"You are a little tired today. You can have a rest first. Of course, if you are interested in here, you can also visit the city, but please note that you should abide by the regulations of our Emerald City here."

Edmund went back to reply after he had explained the matter. Suellen and Hathaway didn't stay in the room.

The Emerald City covers a large area. It presents a completely different style from the city of San filto. Suellen and Hathaway are going to visit the city, and they are also interested in the Emerald Heart library.

If there are hundreds of thousands of books in it, there must be a lot of knowledge sulun didn't master. After wandering in the street for a while, they went to the library.
