Because the terrain in the secret place has not changed much, Su Lun can repair it according to the data given by taling 1 without changing the terrain and environment, which greatly reduces the difficulty of repairing the secret place.

The biosphere construction in the secret realm is more difficult. Ordinary animals are OK, but there are a lot of Warcraft in it. Taling 1 also has many biological genes here. If sulun can use gene breeding technology or cloning, he can directly make them.

But these two spells are eight ring and nine ring spells, which need legendary wizards to master. Even Hathaway is still one level behind.

Su Lun also found some dragon genes here. Of course, these dragon genes are not real dragons, but dinosaurs that have long been extinct in his previous life. There are some dinosaurs growing in the wild of the world, such as Velociraptor, Spinosaurus, Tyrannosaurus Rex, etc., but most of these dinosaurs live in the South.

In some wilderness areas of the southern continent, these dinosaurs can be called overlords. It is said that these dinosaurs first ran out of the secret land. There were no dinosaurs in this plane. The arcane masters captured a large number of dinosaurs from other occupied planes for research.

The strength of these dinosaurs is not bad, such as Velociraptor. Their biological level is level 10 and their challenge level is level 5. It needs several knights to solve it. However, Velociraptor is a social creature, and basically lives with three to six heads. To solve the problem, there is no big knight to lead the team.

As for the most powerful Tyrannosaurus Rex, the biological level is as high as level 17, which is stronger than many Asian dragons. Of course, there are not many dinosaurs at this level.

Some dinosaurs can no longer be called dinosaurs. They have some giant dragon blood in their bodies, and their bodies have mutated. I don't know whether ancient arcane masters have carried out blood transformation experiments on them, but Su Lun guesses that the probability is very high.

Although the secret environment will be serious, the equipment in some places has been preserved and can be reused as long as it is repaired. In order to create a corresponding environment in the ecological park, it often needs various Rune arrays. These Rune arrays have fallen into a state of stagnation because of the original energy interruption.

After a long time of aging, many Rune arrays have become unusable and need to be remade. Su Lun has mastered a lot of runes during this period of time. He has repaired many Rune arrays under the repair standard given by taling 1, and reconnected these Rune arrays to the energy channel.

After staying in the secret place for a period of time, Su Lun returned to the north town to have a rest. The workload of the secret place is huge, so he can only do it bit by bit. Su Lun doesn't want to be busy every day. There is no time for rest.

After this period of work, an open space has been cleared next to the Lord's castle. The open space is now busy. Workers are digging the foundation. The foundation of the wizard tower is naturally very important. The basement of Hathaway's wizard tower has three floors. The lowest floor is a dungeon to hold some prisoners or Warcraft. The second floor is an element pool, The first floor is a sundry room and an ordinary warehouse.

The wizard tower above the ground is divided into seven floors. The first floor is the living room, including the place where servants live, the second floor is the room for guest rooms and wizard apprentices, the third floor is the battle training ground and magic training ground, and the fourth floor is the place for teaching apprentices and storing magic statues.

The fifth floor is Hathaway's laboratory, the sixth floor is where Hathaway lives and is also the location of the treasure house. The seventh floor is the star viewing platform of the wizard tower and the control center of the wizard tower. The weapon system of the wizard tower will also be installed here.

The drawings of the wizard tower have long been determined. According to the strength of Zhenbei City, it will take at least several years to build such a huge wizard tower. The theme construction of the wizard tower is not too difficult. The difficulty is the runes and various energy channels engraved on it. The workers and slaves in Zhenbei city can't do this work, but the wizards can do it themselves.

However, Su Lun soon found that not only ordinary people but also half elves and drow elves built the wizard tower. Although they are not wizards, they also have some spell casting abilities. Now these elves also joined the construction of the wizard tower, which surprised Su Lun a little, but they soon reacted. Whether Karina or grace are also spell casters.

Although they are blood warlocks, they can also build wizard towers after entering the fourth level. Just because of their strength and resources, they don't have wizard towers at all. Even if they join Zhenbei City, it's impossible for Su Lun to support them in building wizard towers.

The construction of a wizard tower almost bankrupted the North Town, let alone three towers. Now Hathaway built the wizard tower, they naturally want to share some profits. Although they can't become the owner of the wizard tower, some areas of the wizard tower can still be used.

Hathaway naturally agreed to their request, on the condition that they needed help to build the wizard tower.

The foundation of the 120 meter wizard tower is 30 meters long. Thousands of construction teams work under the supervision of the drow elves. These soil will be transported to other parts of the city. Under the foundation of the wizard tower, all use the magic of turning mud into stone to turn the original soil into rock.

In some places, hardening is even added to increase the strength. Here, it will be built as the base of the wizard tower, and the wizard tower will be connected with the base with structures. These are reserved for the wizard tower to be upgraded into a floating tower in the future.

The upgraded form of wizard tower is floating tower, which is the initial mode of floating city. Since the destruction of the arcane Empire, the construction technology of floating city has been incomplete, but the technology of floating tower has been preserved.

It takes huge energy to make the wizard tower fly. Although the element pool can not support the consumption of the floating city, the consumption of the floating tower is still OK. The wizard towers of legendary wizards in the world are basically floating towers. The construction of floating towers requires a lot of secret silver, which is not difficult for sulun, who has the associated secret silver mine.

According to the calculation of the grey dwarf Bach, this silver mine belongs to a large rich mine, and there are still a lot of secret silver in it. Now, except some of these secret silver are used for the restoration of the secret environment, all the rest are stored in the treasure house of the Lord's Castle and used when the wizard tower is upgraded to a floating tower.

A large amount of steel is transported from the blacksmith's workshop. These metals melted in the blast furnace and processed by the grey dwarf are already steel. The construction of the wizard tower requires a large amount of steel. The steel skeleton is erected one by one, and a large amount of obsidian is transported. If you have enough money, you can use Obsidian to build all of them, just like the kingdom of Lorens, Rich enough to build walls with obsidian.

Although Su Lun also wants to build a wizard tower entirely with obsidian, considering that repairing the secret place also requires a lot of money, he can only reduce the use of obsidian in the wizard tower. Obsidian is only used in some important areas of the wizard tower, and ordinary marble is used in other places.

In fact, some wizards who really don't have money will use ordinary stones to build wizard towers. Of course, they can also use soil. First turn mud into stone to turn the soil into rock, and then perform hardening on these rocks. Although this is more troublesome, the strength of wizard towers is also very high.

Of course, in this way, the workload of wizards will also increase many times. The workload can make a wizard chop his hands. Generally, wizards with a little money will not do this. Only those poor people will use this method. The effect of hardening is permanent. The great wizard level wizard can make the wood have the strength of steel. If it is rock, the strength will be higher.

The wizard towers that can really travel in the star world are built with a large amount of obsidian, and then add hardening on the basis of obsidian. In this way, the strength of the wizard tower will reach an extremely amazing level.

Sulun sent two thousand dog headed men to the underground world to mine obsidian, but it was difficult to mine Obsidian because of its hardness. In addition to mining Obsidian from the underground world, Zhenbei city also purchased a large amount of obsidian from the kingdom of Lorens.

The craftsmen built according to the drawing requirements. The half elf caster and drow elf caster began to turn mud into stone on rocks and obsidian, while Hathaway performed blessing hardening on those rocks, as did Karina and grace.

In order to speed up the construction of the wizard tower, Hathaway pulled out the clay and rock magic statues she made. When these magic statues first appeared, they frightened the workers. The arms of the rock giants up to three meters were thicker than their waist, and the ground shook slightly when walking, full of oppression.

Those workers were very worried and accidentally trampled to death by these magic statues. However, after a period of familiarity, these workers were no longer afraid of the puppet magic statues. Now they became very curious about these puppet magic statues.

If it weren't for the reputation of wizards and the power of these magic puppets, these people would have climbed up to see it. I have to say that human adaptability is really strong.

Because Zhenbei city began to eliminate monsters in the wilderness, the slaves in the territory began to increase significantly again. In less than a month, the army of Zhenbei City arrested more than 10000 dog headed men, goblins, jackals and orc slaves. Therefore, although a large number of people were used for the construction of wizard tower, the construction of Zhenbei city also did not slow down.

Various public facilities in the north of the town have not been improved. According to sulun's requirements, all roads need to be slate roads or gravel roads. Now the main roads of the city have basically been completed, but some roads in the square city have not been completed. Some parts of the city began to build street gardens or green parks. In the past, in order to catch up with the progress, priority was given to the construction of other buildings. Now with sufficient manpower, they have also started a large number of construction.
