Only the outer walls had changed drastically, much to the amazement of all of the Drintle city's fiefdoms and adventurers.
This was because in just one day, a new ten-meter high wall had been built outside the city's walls.
The ramparts were surrounded by a moat and were so magnificent that they looked like the royal castle of some small country.
Looking at the ramparts alone, they are as good as the walls of the royal city of Esfort.
Originally a small city of only two kilometres square, Drintle will grow by two kilometres on all sides to become a large city of six kilometres square.
In terms of area, it had become nine times larger than the other large cities, and it was now as large as any other large city.
Cain asked Alec and Lula to design the general infrastructure and decided to return to the royal capital.
He took classes at the school during the day, and then transitioned to the city of Drintle after school to continue the maintenance.
This is because the area between the old and new city walls is a grassy field and mainly needs to be mowed and cleared.
However, because Cain's magic would be exposed if the lords and ladies entered, a wall of about three meters is built on both sides so that they can proceed in a straight line from the old gate to the new gate, so that the vast grounds cannot be seen.
Cain is using his magic and is incessantly clearing a vast area of land in Drintle.
'I never thought I'd have to work this hard: ...'
Even though the magic power can be used without limit, repeating the same task over and over again will gradually become boring.
As expected, even Cain felt like complaining.
''Cain-sama, we're almost there. Please do your best!''
Alec also has duties as a deputy, so he and Lula and Dalmatia continue to work together as the three of them move around.
Alec has been asked to publicize to the people of the territory and coordinate with the city's influential people. This is because the castle gates have been increased to two at each gate, so the deployment of guards needs to be reconsidered.
The expansion of the city of Drintor and the arrangements for materials, carpenters and other people for the houses that will be built in the future are left to Dalmatia, an excellent steward.
''Leave that matter to me.
Dalmatia replied so, and is relieved to hear that.
While listening to the words of support from Lula, Cain exercises his magic. No matter how much of the work was done after school, the rough work was done in four days due to Cain's substandard magic.
Lula drew a drawing while Cain was attending the school, and a rough infrastructure drawing had already been completed.
Even if I say drawings, it's just a matter of deciding on the road that will stretch straight to the gate and the section where the academy and orphanage will be built.
The new road would be wide enough for carriages and people to pass through without problems.
Moreover, Lula used her knowledge from her previous life to study concrete. Making the best use of Cain's creation magic, the school and orphanage are considering concrete construction.
Concrete buildings cannot be built without Cain, though.
As the day progresses, somehow the amount of wood for construction gradually increases. Within a few days a large amount of wood had been placed on the site.
'Dalmatia, this wood is ...'
Of course we are cutting down the trees from the forest. It's my messengers who are cutting down the trees. Shall I call on you?
Cain's body shook with a bull as he remembered the time he tried to call the messenger in the mansion before.
''No, you don't have to call them. As much as possible, try to avoid detection by the adventurers in the forest. It's not a good idea to have a good time.
Of course. The work will be done at night when you are asleep, so please don't worry. However, when it comes to building a house, it's difficult for me to do so, so I'm planning to ask the Chamber of Commerce to build it. That will allow money to circulate in the city and is essential to the city's development.
Cain nodded at Dalmatia's words. It can't be helped if there are no jobs in increasing the number of lords from now on. It's the same in every world where lords fund and turn jobs around, like public works, to develop the economy. I learned that a little from a class I took in a previous life. More jobs, more people, more sales for the trade association, and more tax revenue.
Eventually, Cain wanted to turn the current population of only three thousand people, including adventurers, into a city of more than ten thousand.
The work was in sight, and he took a break from the tea Dalmatia had prepared for him.
''I think we're almost ready to settle down.
The land has already been cleared and Cain muttered as he looked at the piles of materials piled up like a mountain.
The only thing left to do is to finish the demolition of the old city walls, and then I think there will be a huge building boom. We have arranged for craftsmen to come to the royal capital through the Chamber of Commerce, so I think the number of people will gradually increase.
Dalmatia, who is waiting behind me, tells me. Cain is once again impressed that it is indeed Dalmatia, the all-powerful butler.
Lula sits next to her and looks at the drawings she has drawn.
''Alright, let's demolish the old city walls.
After swallowing the last sip, Cain stands up and declares.
'It's going to be hard to dismantle that kind of thing, isn't it?
Lula says so, but Cain has unlimited magical power. Rather than dismantling it, Cain finds it harder to go around the city of Drintle again for another round.
Cain puts his hand on the old city wall and lets the magic power flow down.
''Demolition.''
With one word from Cain, the castle wall crumbles with a sound. The stone material used for the castle walls is placed in Cain's item box to be used for cobblestones and other items in the future.
''That's too cheesy for ....''
To Lula's dismay, for hundreds of meters, the walls that had protected the city for decades had crumbled away. Moreover, the rubble of the wall that should have collapsed has disappeared. It was so out of the ordinary that no one could hide their surprise.
Although the vicinity of the city wall is marked as off-limits for demolition, a loud noise accompanying the demolition has been heard, and so the lordsfolk gather around.
And they are surprised to find Cain, the lord who exercised his magic, standing on the other side of the demolished city wall.
Cain stood in front and began to speak to the gathered lords.
''I'm sorry to have startled you all. I am the lord, Cain von Silford Drintle. I couldn't help but get in the way of expanding this city of Drintle, so I had to remove the city walls. As you may have heard the rumors, the city of Drintle will be the city of Drintle up to the newly built city wall that you can see behind me. I plan to build the city along the plots in the future. Anyone with experience in carpentry or who can do civil engineering. If you don't have a job, we need your help. I promise to pay you a commensurate salary, of course.
Cain's words pleased the Lords. Since this area was close to the slums, there were many people without jobs. They had been given publicity by the deputies in advance throughout the city, but many of them were skeptical. Directly in front of their eyes, they were given a new job and nothing but welcoming words to the lords who were offering to pay them a salary.
' "'Ooh-oh-oh !!!!!'
Controlling a handful of delighted lords, Cain continued to speak.
'We will also build new homes in this new area. And the current slums will be demolished. Of course, the people in the slums will live in the houses we have prepared for them, and from now on they will be required to work. Please understand that this is all I have to say. That's all I have to say.
Even the slum people in the demolition zone were happy to be given housing and jobs. Cain turned his back on the assembled lords and moved on to the next demolition site.
One by one, the old city walls were demolished, and the debris was housed in Cain's item box. Then the ruins of the wall are cleared and moved to the next location.
Over the course of a few days, the demolition of the old city wall was all done.
Cain and the others returned to the mansion and took a break in the office.
''As for the future, I've left it up to you guys.
Cain gives Alec the cost of the construction from materials. It's a small bag of white gold coins that I've accumulated so far. There are about a hundred white gold coins inside, which translates to about one billion yen.
It's the materials for demons, the money for goods sold through the trade association, and the money for the glassware sold to the royal family is also in here.
Even so, there is still about the same amount of white gold coins in Cain's item box.
''With this much, I think we can manage. I also asked the royal capital to increase the number of guards. I'll start the rest when the craftsmen arrive.''
Alec said after storing it in the safe in his office.
'It's almost summer vacation and I'd like to stay here for a bit longer. However, Teres has called me to the Malbeek territory, so I'll have to go once. I also need to visit my parents in Tijuana, so I don't think I'll be here that long.
The academy has a summer vacation of about two months. The reason why the summer vacation is so long is because the children of the nobility gather from all the territories, and the ones that are far away from their own fiefdoms take a month to travel back and forth alone.
There are some who have mansions in the royal capital, but most of them live in the dormitories in the school.
''All right. I'll leave it to you in the meantime.''
At Alec's words, Cain nodded.
Leaving the three of them to deal with the city of Drintor, Cain transitioned to the royal capital.
After transitioning to the office of the royal capital's mansion, Cain told Coran and Silvia that he had returned.
''--Cain-sama, I have received a letter from you: ...
I take the letter from a horrified Coran and check the sealed wax crest on the back.
It's the same banner that hangs in the royal castle, as it's always called.
Then you open it and check the inside.
The letter has only one sentence written on it.
'Come to the royal castle as soon as you see it, Lex Terra Esfort.'
Cain sighs loudly. He then hands the contents to Coran. Corran checks the contents and seems to think that he was right.
'Corran, I'm going to the royal castle now. May I ask you to take care of the driver?
Very well. I'll have the carriage ready in front of the house right away.
Corran hurriedly left the office, as he was being called from the royal castle, and went to prepare the carriage.
Called by Coran, who quickly finished the preparations, Cain got into the carriage and headed to the royal castle.
The sun had already set, and there was no carriage going to the royal castle except in an emergency. The gate guards had been informed and were able to enter the castle without any problems.
Cain was immediately ushered into the usual reception room.
As he was drinking the tea prepared by the maid, the king and the prime minister soon appeared.
Cain rises from his seat and takes his civility.
'I'm sorry it's so urgent,'
The King sat in his usual seat, with Prime Minister Magna sitting next to him.
Cain had expected to be blamed again for the Drintle affair, but his speculation was off.
''As a matter of fact, a saint from the Marinefort Church State is visiting this country on an inspection tour. It's right around the time the school is on summer break. It is planned to stay for about a week, but the saint of this world is not much older than you. You will be dealing with Telestia and Miss Silk. And you'll be his bodyguard. They are close in age, and the saints will be more comfortable that way.
I was busy with Drintle's internal politics, but I had another new project waiting for me.
