So far, there are no defensive spells that can resist the magic attack of the power of the twelve rings, even the most powerful mystery lock in the era of the arcane empire. This power is a big killing weapon developed by arcane masters to deal with the gods, but it has completely disappeared after the collapse of the arcane empire.

Now there are few magic particle railguns like sulun. Many wizards suspect that this is the work of the gods, because this weapon can threaten the gods.

Su Lun's book is not the technical data for making the magic particle railgun, but a theory. However, even the theory is very good. The north wind tower of the magic particle railgun already exists. With this perfect theoretical knowledge, as long as Su Lun is given time, he can upgrade the magic particle railgun bit by bit.

It may not reach the level of destroying heaven and earth in the arcane Empire, but it is still possible to surpass the tenth ring. After understanding the importance of these things, Su Lun put away all these books. The value of these knowledge is amazing. Except Su Lun and Hathaway, others have no right to read them.

In the next few days, Suellen, Hathaway and Alex stayed in the laboratory and began to discuss the next development of the north wind tower while studying the data.

The construction of the floating city has been put on the agenda. Combined with the information in the book, Su Lun finally decided to build a medium-sized floating city, which is also the largest one that the north wind tower can bear now.

As for the big floating city, the resources of the north wind tower are still unable to build. Of course, sulun left room for upgrading the floating city when building the floating city. When he has enough financial resources, he can upgrade the floating city.

Sulun plans to transform the floating city with the current Zhenbei city. Although Zhenbei city is an ordinary city, sulun spent a lot of effort during construction. Basically, hardening technology is used for reinforcement in the city. As long as some materials are added in some places, the tenacity of the city will fully meet the requirements of the floating city.

This will not only save a lot of resources and money, but also reduce the time and energy spent on rebuilding the city. In addition, Su Lun doesn't want to give up the spectacle buildings he has spent a lot of time and energy on. In addition, he can't get the materials needed for the site selection and construction of spectacle buildings for a time. He is not willing to give up the magical effects of these spectacle buildings.

Therefore, the best solution is to build a floating city with Zhenbei city.

The current scale of Zhenbei city can accommodate 200000 people. Of course, this scale has exceeded the standard, so sulun plans to give up some unimportant places. After all, the bearing capacity of the energy center element furnace in the floating city is limited, unless sulun plans to build another element furnace or the technology of the element furnace is improved, An element annihilation furnace that provides more energy than an element fusion furnace can be made.

After deciding to build the floating city according to the North Town, the rest will be much easier. Next, we will upgrade and transform the north town according to the standards of the floating city. The laying of various energy channels and the relocation of some buildings and factories also need to be carried out.

Due to the limited location in the floating city, sulun needs to make full use of the limited space as much as possible. Of course, those unimportant buildings or factories are not completely abandoned. The space of floating city is limited, but these buildings and factories can be moved to the half plane.

Sulun has planned to link the developed half plane with the floating city. This half plane will be used as the production base of the floating city. Of course, the premise of doing so is that sulun needs to develop the half plane well.

It took some time to sort out and record the reconstruction of the North Town, and then these works will be divided by taling galaxy. Some simple and repeated works will be handed over to those wizard apprentices for treatment, such as replacing some parts of the city with obsidian and strengthening. Those wizard apprentices in the north wind tower are just in use.

Some physical work is left to the magic puppets, such as cutting off the underground and earth excavation in the north of the town, as well as the excavation of energy channels in the city.

These tasks are not complicated, but the workload is heavy. It can be handed over to taling to command the magic image to work. As long as the acceptance is qualified.

In addition to these works, important things need to be commanded by several people in Su Lun. This part is not in a hurry yet. Su Lun plans to sort out these works, record the requirements and standards, and let them build according to this standard.

After such a division of labor, the workload of sulun and others will be greatly reduced. And because everyone is only assigned part of the work, it can also be kept confidential. Except for sulun, who knew all the content, others only knew part of it.

Many buildings in Zhenbei city need to be demolished, even sulun's palace can't be avoided. The scope of the palace is still too large, which is naturally no problem in ordinary cities, but it is completely wasted in the floating city with tight space resources.

Su Lun was also distressed to directly tear down the palace. After all, the money he spent was not a fraction, so he planned to move the palace to the outer city as a whole, and the outer city of Zhenbei city will be further expanded.

The construction of the floating city takes a lot of time. Sulun has only sorted out part of it now. In the next time, it needs to be built and improved.

After finishing the work of floating city, Suellen and Hathaway began to fight the eye of the evil eyed tyrant. The evil eyed tyrant got an eye the size of a football.

After special liquid treatment, the eyeball has begun to become a crystal. Next, Su Lun and Hathaway need to work on the eyeball together. If you want to make a powerful omnivision eye, you need a lot of precious resources, including secret silver, Mountain Copper and star silver sand.

Fortunately, there are still a lot of stocks here in sulun. In addition, the underground mine has been mining all the time. It is basically enough to make the omnivision eye, but even so, you must be careful.

The eye is a very fragile part, even after crystallization. Once some small things inside are damaged, Su Lun can't repair them again, and there is only one eye. Once it is broken, it can't be replaced.

Under the careful operation of Suellen and Hathaway, the omnivision eye is made bit by bit.
