A magic airship slowly fell from the air.

As soon as it was settled, Princess Caroline... Oh no, Grand Duke Caroline, who has already taken over the position of Grand Duke, led a group of subordinates to meet him.

The cabin door of the magic airship opened and Xu Yi walked out of it.

"Hey, my dear Xu Yi, you are finally here. I've been anxious for a long time." Grand Duke Caroline walked over and gave Xu Yi a big hug. Then, without caring about the gazes of everyone around him, pouted and leaned towards Xu Yi's face.

Xu Yi quickly turned his face and avoided her mouth, but asked her to kiss her face, and then kissed her cheek, which was considered to have completed this obviously more intimate etiquette.

"Hey, Caroline, you are the one who will be married next month, why are you still so bold?" Xu Yi whispered in Caroline's ear.

"Bold? Is there any?" Grand Duke Caroline chuckled and let out a gentle breath, making Xu Yi's ears itch. "If you promise me now, I will go back and get the marriage back immediately, what do you think?"

"Nothing." Xu Yi retorted lightly, let go of his hands, gently pushed Grand Duke Caroline's body away, then coughed lightly, and said seriously: "Are you ready?"

Grand Duke Caroline shrugged: "I don't have much to prepare here, anyway, I'm just waiting for the people you sent to come."

"Um."

Xu Yi nodded and waved behind him. A group of people wearing various uniforms of the Xinfei Chamber of Commerce came out of the magic airship one after another.

"This is some of the personnel responsible for initial exploration and mapping that I came here with. Come, let me introduce you, Gustalo, the manager responsible for the magic defense project of the Door City system, this time."

A tall middle-aged human man walked up and bent down to Grand Duke Caroline and bowed.

"I've met your grand lord."

Grand Duke Caroline looked him up and down, and stretched out his hand with a smile.

"Since President Xu sent you here, I fully trust you. Director Gustalo, please give me all the overall defense of Dore City."

Gustalo hesitated for a moment, held Grand Duke Caroline's stretched out hand and kissed it gently, and responded respectfully: "I will serve you wholeheartedly."

"Very good." Grand Duke Caroline's eyes circulated, and he glanced around the other employees of the New Flight Chamber of Commerce behind Xu Yi, making an invitation gesture. "I have set up a banquet in the city. Please ask President Xu and everyone to follow me."

Xu Yi shook his head and looked at Gustalo and said, "Time is tight. They don't have so much time to attend any banquets. Gustalo, you should hurry up and check the situation of the city wall and try to get out the approximate data today. The R&D center is still waiting."

"Yes." Gustalo immediately nodded and responded, then turned to Caroline's justice: "Hisser Dagong, please send some people familiar with Dor City to do this work with us."

Grand Duke Caroline was a little stunned: "Don't you need to be so anxious, right? You come here so far, at least you have to have a meal first to adapt."

"No need, we don't actually have that much time. I don't know when the next wave of attacks from the Maru Empire will come. And as long as they come again, they will inevitably be a very fierce attack. You don't want the precious land you just got to be snatched back by the Maru Empire in the blink of an eye, right?" Xu Yi said.

Grand Duke Caroline sighed softly and waved backwards, and two officials from the Duchy of Drake who followed her to greet him quickly walked over.

"Supervisor Gustalo. These are two officials in charge of the overall defense of Door City. If you have any questions, please ask them."

"OK."

Superintendent Gustalo was no longer polite and went up to talk to the two officials.

"Xu Yi, I'm very surprised many times. How did you train all the employees of your chamber of commerce to look like this? It seems that they only have work in their eyes, nothing else." Grand Duke Caroline looked at Gustalo and another group of New Flight Chamber of commerce employees who also came over to discuss it in a lively manner, and couldn't help but sigh.

Xu Yi smiled and said, "It's not as exaggerated as you said. The employees of our chamber of commerce are very good at playing when they are idle, but they are always very serious when they work. This is my strict requirement for them. Of course, they can accept and consciously do this, mainly because they feel that their work is very fulfilling."

"Sense of accomplishment?" Grand Duke Caroline frowned slightly. "What kind of sense of accomplishment?"

"Think about it, because of their efforts, the inconspicuous small city of Dor City can resist the attack of the huge Marlow Empire. Isn't there a sense of accomplishment?"

Grand Duke Caroline was silent for a moment and asked back, "Xu Yi, you answered me seriously. After the magic defense project of this city system is built, can Dor City be extremely stable and enough to withstand the attack of the Marlow Empire?"

"City defense has never been solved by relying solely on a system, but I can tell you that as long as there is no problem with Dor City in other aspects, this defense system is enough to keep Dor City for at least one month and will not fall into it no matter how many troops the Marlow Empire sent." Xu Yi replied seriously.

"What if the Malo Empire dispatched a magician?" Grand Duke Caroline asked again.

"Magic?" Xu Yi laughed. "Hey, if the Malo Empire is willing to risk the taboo of all magicians on the continent and send a magician to attack other countries in violation of tradition, then he will have lost half of it. As for the Malo Empire, I admit that the magician's personal ability is very powerful, but you have to remember that a person plays a very limited role in war. Even if the Malo Empire really dispatches magicians, it will not be possible for this magic defense system that our Chamber of Commerce has carefully created after long-term research and development."

Grand Duke Caroline looked at Xu Yi in confusion, not understanding why he was so confident.

The magician has always been the most top combat power on this continent. In the historical wars on the Continent of Sainz, as long as the two sides can have more magicians of the great magician level, it is enough to decide the outcome of a battle.

Once even the magician appears, it will be enough to quickly turn the victory or defeat of this battle to the side with the magician.

The reason why the Marlow Empire and the Candela Empire were able to stand on the Continent of Seines for so many years was that in addition to the fact that their national strength remained absolutely strong most of the time, when they declined, there would be magicians in charge, which made it very important for other countries to fail to truly defeat them.

The magician union determined at the beginning of its establishment that the tradition of magicians not being allowed to participate in the war of invading other countries. Although it ensured that these two empires could not easily invade other countries, it also allowed these two empires to stand firm.

However, this tradition is just an unwritten rule commonly known as the agreement. If the Malo Empire really breaks this tradition, except for the Candela Empire and the Mana Magic Kingdom, which has the third largest number of magicians, can restrict it, other countries and forces will not be qualified.

This time, the Kandra Empire and the Malo Empire were extremely rare to unite, and even joined forces with the Mana Magician Kingdom and other countries to declare war on the New Flight Chamber of Commerce, which made the New Flight Chamber of Commerce’s most worried about the issue if the other party dispatched magicians to participate in the invasion war.

Although the other party has not broken the tradition so far, no one can guarantee that the other party will never be able to do this.

After all, even something almost impossible like joining forces between the two empires has happened, and it is not completely impossible for some other incredible things to happen.

However, Xu Yi now told Grand Duke Caroline that the role of the mage in war is very limited, and it doesn't matter if the Malo Empire really dispatches the mage, which makes Grand Duke Caroline unable to understand for a while.

"Tell you the truth, Caroline, the ultimate goal of our Chamber of Commerce in developing this urban defense system is actually the magician that may appear. For any conventional army of the two empires, even if we do not include our New Flying Chamber of Commerce's guards, even the Duchy of Delar's own army is not very afraid, right?"

"Well..." Grand Duke Caroline nodded slightly.

Before, when the Duchy of Drake joined forces with the army of the Kingdom of Lampari to fight with the Marlow Empire and the Frank Kingdom coalition forces, the other party had no power to fight back on the front battlefield.

Under the huge combat power gap between the two sides, the so-called gap in military strength is simply irrelevant.

In fact, even if we did not join forces with the Kingdom of Lampari, the army owned by the Principality of Drake itself would be removed, not to mention that the regular army of the Marlow Empire would be eliminated at least there would be no pressure to face the army of the Kingdom of Frank.

"So, the reason why I will assist you in building this city defense system in Dore, not far from the border of the Malo Empire, is to put it bluntly to defend against possible attacks by the Malo Empire, or even defend against possible magicians." Xu Yixu said. "Think about it, if even the mage cannot capture this city, what do you think the Malo Empire will think? What will other countries on the mainland think?"

Grand Duke Caroline thought for a while, then smiled.

"If even the mage can't do anything to us, it means that this land will truly fall into the hands of our Drake Principality and no one can take it away."

"That's right. At that time, you will no longer be just the Grand Duke of the Duchy of Drake, but Her Majesty the Queen of the Kingdom of Drake." Xu Yi smiled. (To be continued...)
