Doron decided to pay the bill because the royal family was really rich. He hesitated before, because the bill was a bit scary. You know, he promised Anna that 20% of the bills were to pay the bill with gold coins.

In contrast, gold coins are the least valuable in the eyes of the strong, but for a noble, there must be enough gold coins in the territory.

The financial business in this world is relatively simple, but not in the primary.

However, this little gold coins would not make the Marshal. After all, such an expensive position is worth the money. Anna Li was not a scam. Anna did not leave before, and she was asking the magician to strengthen the position day and night.

All of these are in the cost and are not surprising at all.

For example, after entering the tunnel, there is a solid ice blocking the road, which prevents the enemy from forming an impact formation.

This piece of ice was reinforced by the magician day and night, and it was as hard as metal and difficult to destroy. Can you use it as an ordinary ice cube?

As for various long-term magic traps, they are automatically identified badges and have huge network computing power.

The royal family also has a similar magical structure, which can act as a computing core and deal with traps spread out by this network. The magic tower itself also has this ability, but the magic tower's biggest function now is to support all locations.

Half-piece magic tower and Void Magic Monument, these two are the most valuable things.

As mentioned before, the Void Magic Monument was originally a universal model, but after installation, the magician sacrificed day and night, and the level was greatly improved.

The important thing is that it is well integrated with the half-magic tower and can exert its maximum power.

On the third day, Anna Li received the money and started a handover business with the royal family. Her own more than 30,000 people crossed the Ice Wall, avoided the army of the God of Magic, and headed east. The army of the God of Magic did not chase this army, but still attacked the Royal Legion.

This made Li Anna feel worthwhile. She sold her position and the army of the God of Magic cooperated to let herself go.

Anna Li marched all the way, and after a few days, she returned to Mithril City.

After returning to Mirsin City, Anna Li quickly came to meet her two senior brothers.

The fourth senior brother's face was a little round. Although he was not that fat, he was still affected by this face. However, he looked kind and looked harmless.

Seeing Anna Li, the fourth senior brother smiled happily and said, "Little Anna, I'm finally back. I'm still afraid that you will be cheated by the royal family."

"What kind of tricks are there? The royal family is following the rules. If they can't cheat me, I don't dare to cheat them. I just say something and follow the rules. It's very boring."

"That's good. Look at my design and arrangement of Mithril City these days."

"Okay." Anna Lee nodded to Lynn, sat down and began to investigate the documents.

The design of Miltese City is really adapted to local conditions. Because it is rich in Miltese and geothermal heat, the construction here may not be that cheap, but the operating cost is very low.

The Mirsilian Cave itself is connected to the underground world, but the passage is narrow and it is impossible to mobilize troops.

There are three passages in total, two of which are arranged with tracks and reinforcing, and metal trains can be carried out. Transportation is not a problem. The remaining one is too narrow and blocked with magic. If there is no identity verification, it will kill step by step.

The underground passage is not very meaningful, mainly to prevent the enemy from entering Mirsin City from the underground world.

Therefore, the export of the three channels has been built for military chemical fortifications. Anyway, no large-scale transportation of materials cannot be carried out. Just use it as a simple channel for exchanges, and safety is the first priority.

Then the fourth senior brother heard that Miltsilver City was going to become a center and a military base, so he simply played a big Miltsilver City's new design extending upward from the underground cave, like a towering tree, taking root underground.

The material of this big tree is Mithril ore. If the mitril content is low to a certain extent, the ore will not be worth refining. However, the properties of this ore itself are also very unique. The mage of the Duke's leader simply developed a fusion method and added other substances to it, so that the ore with extremely low mitril content can be redissolved and turned into a hard artificial stone.

This is much stronger than artificial stone made from raw coal, and its attributes are also stronger than obsidian.

Therefore, this is a huge magic city, with the underground part being mixed in structure, and the above part being the core is a huge building with a diameter of nearly kilometers, rising upwards, like the design of Mount Vajra. However, Mount Vajra is a structure that gradually narrows upwards, while Mirsin City is a bit like the Demon Worm Forest.

The huge core city, like a banyan tree, drooping many thick stone pillars downwards.

Such artificial buildings completely protect the entrance of the Miltese Cave, and the ground surrounds the Miltese City, and builds an outer city.

The outer city is made of ordinary artificial stone, with only the key locations, and new Mithril artificial stones were used.

It’s not that Mirsin City cannot afford this money, but that Mirsin artificial stone has to be provided to other large buildings under the Duke’s rank, which every city needs.

In this way, the financial problems of Mithril City were also solved.

Anna Li was also shocked when she saw the construction progress. The ancestors really spared no effort to support herself. The only 100 Taoist priests in this world were sent, and then the students from Asla Academy were also sent to do tasks.

The above-ground part of Mirsin City has begun to take shape. Although the underground part is much different, it is not too anxious. The magic array that uses geothermal heat has been completed, and the rest can be taken slowly.

The Mirsin City on the ground has a huge core building mask, which is no different from a small city, five miles away.

Then the outer wall extended another two and a half miles away.

Outside the outer walls, many mountain bags were flattened, leaving behind the prototypes of Mithril Fortresses. The material replacement has been completed, and the most troublesome parts of the refining work have been completed.

All that remains is to work slowly and work hard, enriching the city's heritage bit by bit.

This Miltese City is not as big as a Duke's, but the diameter is more than ten miles. If you consider the various Miltese fortresses on the periphery, the diameter is almost twenty miles.

The fourth senior brother said: "The outermost periphery itself is within the protection range of the magic shield."

"Why is the city wall not built outside?" Li Anna asked.

"When I built this city wall, I used the terrain and underground structure. This circle of city walls is the most solid. Even if the outer side is built, it will be as prominent as other cities at most. Besides, when Mirsin City needs a larger territory in the future, it will be expanded to the city wall."

"A second waste."

"We shipped a lot of raw coal, and the royal family also sent a lot. What I asked for was part of the payment. The royal family was very happy to use raw coal to pay the bill. I needed a lot of raw coal to build. After the construction was completed, there would be a lot of coal slag to make artificial stone. The foundation of the outer wall could be repaired now. As for the completion, there was no hurry. After the construction of the Mithril Academy, let the students build slowly."

Anna Li went to look at the pictures again and found that the City Lord's Mansion, the Misilian Academy, and the Misilian Legion's garrison had all been planned.

"Fourth Senior Brother, the city lord's mansion is so luxurious, you are using your power for personal gain!"

"Anna, of course I have to use my power for personal gain. From now on, I will take root here and do things for you. I have to be ashamed. Moreover, this design must consider safety issues. My combat effectiveness is not as good as you two, so I have to keep the place where I live and build it high-end enough."

"Okay, if you die, it will be a huge loss for me." Anna also admitted that the design of Mithril City is still very good, adapted to local conditions and is strong enough. On the design drawings, after the final completion, it will be beautiful.

The Mithril walls are enough to attract attention.

But in fact, the amount of mitral contained in a mile-long city wall may not be enough to create an alloy dagger.

So beautiful, it uses silver and various experimental alloys.

In the future, Mithril City may be a commercial city and a strategic location. If others believe in you, you have to show enough strength. This is like a businessman who needs to get a few luxury carriages when he meets a customer.

The Mirschin Tower in the core has now become a giant with a diameter of kilometers, and of course the internal facilities are complete.

This is much more powerful than an ordinary magic tower. The Mirsier Legion simply stationed directly inside to connect to underground caves.

Anna Li looked at the bills casually, which was quite scary, but it was worth it. The fourth senior brother designed all this, but in practice, Xiacheng helped Xiacheng, the computing core of Mount King Kong, to help calculate and build this city, without wasting time and strength, nor energy.

For example, the refining of the core Mithril City uses a large amount of magic furnaces. These magic furnaces consume raw coal.

The used raw coal and residue are transported directly to the periphery to create artificial stones. These artificial stones will be further processed in the future and will all be replaced with Mithril artificial stones.

Now it is just a key node to ensure the city's defense.

As for the Mithril Fortress on the periphery, it is purely the result of artificial transformation of various mountains on the original surface.

The fourth senior brother said, "After the protective cover is supported, the soil I want will arrive. When the entire formation is running, the magic plants can be planted on the ground."

"This artificial lake is a little small, right?"

"When water is supplied to the underground world, although there is water in the underground world, it is best not to use it, and it will change the geological structure. When there are more people in the Mithril Cave underground, you can only send water from the ground. Fortunately, it is an ice field and there is no shortage of water, so I built a small reservoir on the ground."
