The location of the city of Dole is delicate.

The city originally belonged to the Frankish kingdom and was located in the northern part of the Frankish kingdom, near the border between the Frankish kingdom and the Maro Empire.

Because the northern part of the Frankish Kingdom and the Maro Empire is also divided by a mountain range, and the city of Dore is stuck at the exit of a valley with different levels of this mountain range, which can be regarded as holding the throat position of this communication artery connecting the Frankish Kingdom and the Maro Empire.

Previously, the Frankish Kingdom and the Maro Empire had always had a good relationship and could be regarded as an alliance, so the city of Dole only served as a transportation hub.

And now, with the fall of the Frankish kingdom, the area where the city of Dore is located has been divided under the name of the Duchy of Drac, and the city of Dole has been transformed into a very strategic location.

If the Maro Empire wants to invade again, Dore is a point that is impossible to ignore.

Therefore, Xu Yi cooperated with the Duchy of Draco this time, preparing to build a complete urban defense system for the Duchy of Drak, and with this defense against the invasion of the Maro Empire, Dore City became the first choice.

As Xu Yi said, the purpose of developing this system is first to provide the entire city with a complete set of magical protection systems based on military magic machinery, which can easily resist the attacks of the army of the Maro Empire.

The ultimate goal is that when the other party even dispatches a magister, they can complete the defense task and make Dor City impregnable.

But there is a serious problem with this system, which is that it is too expensive.

If Dol City, a not very large city, wants to fully arrange such a system, according to the budget made by the Xinfei Chamber of Commerce, it needs to invest at least more than eight million gold coins.

Therefore, even if the New Flying Chamber of Commerce makes a move, there is no way to arrange such a system for all the cities currently controlled by the Duchy of Draco in one go, and can only pick out the final few cities to be arranged.

The city of Dore is just one of them, and it will be installed in several cities near the northern border of the Malo Empire in the Duchy of Drake. Completely block the route of the Maro Empire's southward invasion of the Duchy of Drake.

For this reason, the Duchy of Draco is expected to invest a total of 70 million gold coins.

Although the Duchy of Draco has made a financial income guarantee by vigorously developing the magic industry over the years, it has not been able to come up with such a huge investment.

Therefore, according to the agreement between the two parties, the Duchy of Drake will sell one-third of the various mineral resources in the newly acquired 170,000 square kilometers of land in the former Frankish Kingdom to the Xinfei Chamber of Commerce, and cooperate with the Xinfei Chamber of Commerce in the development of the remaining mineral resources. This is considered to be used as payment.

Because the mineral resources involved in this agreement are too huge, there are even some discordant voices within the Duchy of Deraar, claiming that the Grand Duke Caroline is simply using the hard-won mineral resources to please the Xinfei Chamber of Commerce, and it can even be said that he is betraying the country!

However, from a practical point of view, with the current ability of the Duchy of Drake, there is no way to effectively develop and utilize these mineral resources, but it is handed over to the hands of the New Flying Chamber of Commerce to cooperate in the development, but it can be fully utilized.

And the most important thing is that the Duchy of Draco is inseparable from the Xinfei Chamber of Commerce at all.

If you lose the support of the Xinfei Chamber of Commerce. It is impossible for the Duchy of Drake to develop to this point, and it is impossible for it to confront a behemoth like the Maro Empire.

Therefore, compared to the voices of doubt and opposition, the Principality of Drake is still the most vocal in favor of Archduke Caroline.

This time, the Duchy of Draco directly annexed as much as 170,000 square kilometers of huge land in the Kingdom of Franks, which expanded the territory of the Duchy of Draco by nearly twenty times at once, which can be said to have completed the greatest feat in the more than 300 years since the establishment of the Duchy of Draco, and even the former Grand Dukes of Dedraco did not dare to imagine.

With the support of such merits, the prestige of the Grand Duke Caroline is naturally beyond doubt.

Because of this, there are now many nobles in the Duchy of Drake who have raised their voices. hoped that Archduke Caroline would be crowned king directly, but was vetoed by Archduke Caroline.

"I don't understand what these guys are thinking. Archduke Caroline smiled disdainfully on her still flamboyant face. "They are nothing more than expecting me to be crowned queen. Then it's just a matter of re-sealing. Hmph, these guys are staring at this new land. These uninformed fellows must be thinking about getting a bigger piece of territory right now. ”

"It's normal, it's an aristocracy after all. Gaining more territory was originally a tradition of the nobility, and it also represented the glory of the nobility. Xu Yi said with a smile.

"Cut. Even if I give them a large amount of territory, will they have the ability to defend it?" the mockery on Archduke Caroline's face deepened. "It's like you. Xu Yi, you still seem to have a title of earl in the Duchy of Stantin, right? How many territories you have under your name, does it have any impact on you? Who will judge you because your territory is not big enough?"

"I've been emphasizing that I'm a businessman, a nobleman. Magicians or not, it's just incidental. Xu Yi shrugged his shoulders and said with a relaxed face: "It doesn't make sense to compare the size of the territory with me, it's better to compare with me who makes more money every year." ”

"How much money do you make every year?" Grand Duke Caroline glanced Xu Yi up and down, narrowing his eyes slightly. "Xu Yi, can you tell me how much money your Xinfei Chamber of Commerce can make in a year now?"

Xu Yi suddenly laughed: "This is not an unsightly secret, you don't need to ask in this tone." To tell you the truth, last year, our chamber of commerce earned about 150 million gold coins a year. ”

"150 million gold coins!" Archduke Caroline suddenly gasped. "The gods are above! I always knew that your Chamber of Commerce made a lot of money, but I never expected that it would make so much! The annual financial revenue of our principality is less than 20 million gold coins!"

"That's when you were just a small principality. Now that you have acquired this large territory, as long as you operate it well, I think that in a few years your annual financial income can easily surpass ours. Xu Yi smiled. "In addition, I also need to tell you the fact that our Chamber of Commerce's income statement at the end of this year is probably going to be ugly. ”

"This is not surprising, after all, this year, your Xinfei Chamber of Commerce escort team also directly participated in the battle. Fighting a war is a very expensive thing, if it weren't for the absolute combat power advantage of the military magic machinery you produce. If the war continues for a long time, whether it is our principality or your chamber of commerce, it will definitely be dragged down by the two huge empires of the Maro Empire and the Candela Empire in the end. ”

"You're right, so we can't delay, we have to end this war in the shortest possible time. Xu Yizheng said.

"How?" said Archduke Caroline, frowning. "The Maro Empire and the Candela Empire are too deep, and they both have so many mages in charge. We can only be completely passive when facing them, and it is up to them to decide when to end the war. ”

"Not necessarily. As long as it hurts them and lets them know that continuing to be in a state of war will only hurt them more, they will actively choose to end this war. Xu Yi smiled dangerously. "First of all, I need to tell them that the Magus is not so safe. ”

Grand Duke Caroline looked at Xu Yi suspiciously.

In the past few years of getting along, Xu Yi has shown more than once that she doesn't care about the Magister, and even dismisses it, which makes her very strange.

It stands to reason that Xu Yi himself is already a magister. Then he should know better than anyone how terrifying the Magister's abilities are.

Although the military magic machines developed by the Xinfei Chamber of Commerce are also powerful, the most terrifying thing about the Magister is that he is far more flexible than the military magic machines, and it is difficult to really limit them.

Moreover, a magister is not as laborious as a great mage, and once a mage is allowed to do it with all his might, the damage caused is extremely terrifying.

If it's just defense, maybe you can think of a way. But if you want to counterattack, it will be a big headache for the powerful destructive power caused by the Magister.

This is one of the main reasons why Grand Duke Caroline believes that although they easily defeated the regular armies of the Candela Empire, the Maro Empire, and other countries on the frontal battlefield, they still have an absolute disadvantage in the overall situation.

With the military magic machinery produced by the New Flying Chamber of Commerce. They can easily defend themselves against the attacks of the two imperial camps, but it is almost useless to counterattack.

Don't talk about the Magister. Judging from the background of the two sides, it is too far apart.

"Our best choice now should be to consolidate the results we have so far, absorb them well, and then improve our own strength, so that we can have the capital to truly compete head-on with the two empires. Words of rash action. I don't think it's a good choice......" Hearing the hint of madness revealed in Xu Yi's words, Grand Duke Caroline couldn't help but persuade.

"It's your choice as the head of a nation, and that's right. But ......" Xu Yi smiled and patted her on the shoulder. "Have you ever thought about the question, what is the reason why our side can easily defeat the two empires on the battlefield now?"

"Of course, it's relying on the military magic machinery provided by your Chamber of Commerce. What else?" asked the Grand Duke Caroline, puzzled.

That's true, but it's not entirely accurate. Xu Yi shook his head slightly. "In fact, in this many battles with the two empires, we can find that in fact, the two empires have also done a certain amount of research on military magic machinery, and many military magic machines have been put into practical use. And we were able to defeat them easily, relying on the current technological superiority of our Chamber of Commerce in military magic machinery. Have you thought about it, if after a long time, our chamber of commerce has no technical advantage in this area, what will be the result?"

Grand Duke Caroline's face changed slightly: "No...... Your Chamber of Commerce's military magic machinery is obviously so much stronger than them, how can they catch up. ”

"Nothing in this world is impossible. Therefore, we must take advantage of the fact that their technology in this area is still at an absolute disadvantage to win enough benefits for ourselves. ”

"Are you going to ......," Caroline looked at Xu Yi in disbelief.

Xu Yi smiled again and patted her on the shoulder: "Wait for my good news." (To be continued......)
