The failure of the element fusion furnace test did not cause any impact in the north of the town. Even except for sulun, others did not know about the experiment. The big explosion in the half plane did not affect other places at all.

Although the half plane was bombed with holes, the north city of Zhenbei still looks prosperous. The morning sun dispelled the mist shrouded in the city, and the Northern Pearl also woke up.

As soon as Suellen got up, Angela and Anna brought the breakfast they had already prepared, a delicate fruit salad, a large ham sandwich, and a piece of roast meat with attractive aroma.

"If you eat these things every day, you will get tired of them no matter how delicious they are." Suellen took a taste of breakfast and said.

"When you have time, let Frodo cook the spicy soup, bean curd, fried dough sticks and small steamed buns." Su Lun said while eating.

Having not tasted these flavors for more than ten years, Su Lun suddenly wanted to eat them once.

After su Lun had breakfast and went out, others in the wizard tower had been busy in an orderly way, because the palace in the north city of the town had been demolished. Now Su Lun has moved to the north wind tower.

Although the north wind tower is not as large as the palace, it also has many advantages, that is, the room is close, which is convenient for him to visit at night. When you are interested, you can string all the rooms of Chris, Hathaway and Karina at once.

After breakfast, Su Lun didn't go directly to the laboratory, but went to Beifeng college. During this period, Beifeng college recruited more than ten wandering wizards under favorable conditions. These wandering wizards are generally middle and low-level wizards.

As for recruiting high-level wizards, this possibility is very low. After all, most high-level wizards will choose to join a wizard organization or establish a wizard family.

Compared with low-level wizards, high-level wizards will spend a lot of time on various experiments. These experiments need a lot of magic materials. They only rely on themselves. It takes a lot of time to collect the materials for their experiments.

Wandering wizards need to spend a lot of time collecting materials or earn a lot of money to buy materials. In this way, wandering wizards don't have much time to experiment, which makes their strength and knowledge far behind those college wizards.

Although these low-level wizards recruited by the north wind tower are of average strength, they are enough to teach wizard apprentices. Now it's not necessary for Hathaway and Alex to spare some time to teach them every month.

Now Beifeng college has thousands of wizard apprentices. Of course, according to the normal promotion probability, about 60% of these people will become first-class wizards, and the rest can only be wizard apprentices.

The various resources of the wizard college are limited, and it is impossible to open the supply to all wizard apprentices. Moreover, those wizard apprentices who want to be promoted to become official wizards because of their own qualifications may consume five or even ten times more resources than those with good qualifications.

Like all wizard colleges or wizard organizations, Beifeng college is such a wizard organization. The wizard college does not supply all the resources needed by Wizard apprentices, but requires wizard apprentices to exchange all kinds of work, even knowledge.

To become a wizard is not a simple thing. In addition to their own efforts, other knowledge, luck and so on are indispensable.

Although Beifeng college has only been established for a few years, it has developed very fast with the support of Beifeng tower and Su Lun. Looking at the many wizard apprentices who hurried forward in the college, Su Lun is excited. Looking at these people's eyes is like looking at a group of green leeks.

These wizard apprentices are the important labor force in the floating city in the future. As the era of the arcane Empire, the floating city is also the highest wisdom crystallization of wizards. If you want to give full play to him, you need a lot of wizards to work.

There are a lot of jobs for them in the floating city. Although the taling is very intelligent and can help Su Lun control the whole floating city, the cost of taling is too high. Even Su Lun can't make hundreds of Talings to work in the floating city.

Perhaps there is such a huge city completely controlled by the tower spirit in the legendary mechanical mirror of nirvana. The legend of Nirvana mechanical mirror of clocks and watches is a world created by the great arcane masters in the era of arcane empire.

The world is a magical plane. Its residents are all kinds of magical statues and other constructed creatures. In addition to these constructed creatures, there are Fermi ants. These creatures are not very friendly to outsiders.

It is said that the floating city in the era of the arcane empire is still preserved in the mechanical mirror of nirvana. There is a magic image factory in the whole mechanical plane, where you can produce all kinds of magic image structures by yourself. But since the destruction of the arcane Empire, the mechanical mirror of Nirvana has been closed. Until now, no one has been to that world.

The floating city designed by Suellen will have 500 to 100000 people living, including at least 3000 wizards. At present, there is a large gap of wizards. However, with Beifeng college, as long as it lasts for more than ten or twenty years, these wizards will eventually get together.

After a tour of the north wind college, Su Lun returned to the north wind tower.

Astrology center.

Hathaway's fingers shook slightly, a flash of light flashed, and then a three-dimensional image appeared in front of everyone.

"This is the first phase model of the floating city. In our plan, the city will have a perfect ecosystem, which can simulate the environment in the main material plane to the greatest extent."

"It includes life support system, air circulation system, water circulation system and element balance system."

"The life cycle system is used to transform the garbage produced in the floating city into various nutrients and other substances to maintain the growth of other organisms in the floating city."

"The air circulation system consists of twelve air compartments and six conversion Rune arrays. They can purify, transform and decompose the air, release the air needed by ordinary people's life, and connect the outside of the wind element, which can provide us with sufficient air."

"The water circulation system consists of three artificial lakes. Purification systems will be installed in the artificial lakes to purify various water sources into harmless and drinkable water sources. Of course, drinking water and domestic water are still different. In addition, we have opened up a water element channel to obtain water sources from the water element level."

"The element balance system is used to balance the four elements in the floating city and keep the four elements in balance. There will not be too many elements that will affect the balance and eventually lead to element collapse."
