The first ceremony lasted until noon, and Roland, who was also the honoree, narrator and host, was exhausted by the end, but the ceremony finally ended with the sound of bells and salutes at noon. Pen, fun, pavilion www. biquge。 Info returned to the castle sweating profusely, and as soon as he stepped onto the third floor, he saw Anna leaning against the office door with a smile on her face.

"What's wrong?"

"You'll know when you go inside," she blinked, her pretty lake-blue eyes.

It can't be some kind of trick show, Roland pushed open the door in confusion, and then froze in place - only to see twelve witches standing in two rows, with Shujuan and Wendy at the front. Seeing the prince appear, everyone lifted the corners of their skirts, bent their knees, and bowed.

"Ahem, you guys are ......"

The scroll was the first to speak, "Your Highness, your actions are proof of everything you have said, and the sisters are deeply grateful for it. No words can describe how grateful we are, and please let us continue to serve you in the future. ”

"I see," Roland breathed a sigh of relief, "I thought you were going to quit en masse." ”

"Poof," Wendy couldn't help but laugh, "how is it possible, Your Highness, this is the sacred mountain that witches dream of." As long as you don't kick us away, we want to be able to live here forever. ”

"And that's what I want to see...... Actually, you don't have to be like this, I'm not only helping you, I'm helping myself. Don't be too serious, I prefer your relaxed appearance. ”

"Well, I'll just say you don't have to be so formal," Lily snorted, "Look, he's still thinking we're being too serious." ”

"How can you say, didn't you just agree to come down in one bite," Miyue muttered in a low voice, "Traitor!"

"Alright, let's go to the dining room first, Your Highness still needs to change your clothes," Shujuan helplessly held his forehead, "By the way, I heard Miss Anna say that you have been sleeping late lately, please take care of your body, you must not fall down until that goal is achieved." ”

"Don't worry," Roland smiled, "I'm fine." ”

After the witches rushed out, only him and Anna were left in the office.

"Why, do you want to thank me too?" Roland teased her.

"Hmm...... I want to say the same as they are," Anna curled the corners of her mouth, "and no words can describe my gratitude. ”

And then ...... Want to live in the Frontier all the time?"

"Not necessarily. ”

Roland was stunned, and his heart jumped, "Why?"

"Because you're not going to stay here forever," Anna said, tilting her head, "...... And wherever you go, I'll always follow you. ”

A warm current suddenly surged in his heart, and her thoughts had never changed since the day he met her. Whether it was in the face of an invitation from the Mutual Aid Society or in a critical moment against the evil beast, she chose to stand with herself.

At this moment, Anna suddenly took two steps forward and hugged him gently.

"Wait, there's sweat. Roland reminded.

The girl didn't answer, but put her head to his chest, as if trying to write down the taste, and took a deep breath. He finally gave up his plan to push her away, put his hands around the other party's white neck, and never let go for a long time.

......

After lunch, Roland took a cold shower and quickly got to work.

He called in Carl Van Burt and spread out a detailed map of the border town, pointing to the location of the Chishui River, "I want to build a bridge here." ”

"Isn't it a pontoon bridge?" Karl Si pondered for a moment before he spoke, "With all due respect, Your Highness, the Chishui River is nearly a hundred meters wide, and it is almost impossible to build a stone bridge, even if it is an arch bridge, it can only cross a third of the distance at most, and the water flow of the Chishui River is so great that the piers cannot be footed at all, and even a stone pile as thick as a person will be washed down...... There is not a single bridge over the entire river, except for raft crossings and pontoon bridges. ”

"It's not a stone bridge, it's a bridge of steel," Roland explained, "and it's three spans, and the middle pier will be solved by a witch." All you need to do is put the approach bridge in place in advance. However, I asked for the bridge to be raised at the head of the bridge so that the river sailing boats could pass through and the mast would not touch the bottom of the bridge. ”

"Isn't that a bridge to the sky?" Karl wondered.

"It's only about six or seven meters above the ground," he sketched a schematic diagram of the three-span iron bridge, "and in order to better develop the south bank and the construction of the dock in the future, there must be a bridge on the river that does not affect the passage of boats." Although the pontoon bridge is simple, it itself is equivalent to blocking the river channel, which is not conducive to subsequent development. ”

Roland's trip to the royal capital of the First Army expedition gave Roland a lot of inspiration - he found that the rivers in the Grey Fort were well connected, and that most of the major cities were built next to several major rivers. If we carry out domestic operations in the future and have several shallow-water heavy gunboats, it will definitely be a sharp weapon for providing fire support and attacking cities and seizing land -- after all, the power of naval guns known for their caliber is far from being comparable to that of field artillery. In order to build a ship, he first had to have a dock, so the plan for a steel bridge came into being.

"But I don't have any experience with bridges......," Carl hesitated.

"Me didn't either," Roland shrugged, "just like the first time you can slowly figure it out, you can first set up a bridge on the shore for testing, and then move to the Chishui River if it's okay," he instilled in him the construction concept of overall prefabrication and one-time hoisting, "It's like installing a water tower, with hummingbirds to reduce its weight, and your student Anna to help assemble and weld, it won't be difficult." ”

"Compliance...... Life, Your Highness. He nodded.

"There's another very important task for you," the prince said, moving his finger to the castle area, "I intend to enlarge the backyard and enclose all the open spaces on the high ground, and build a three-story house here. ”

If all goes well, Tilly's five witches will arrive in Frontiertown next month, and there will be no more rooms left in the castle. Although it can be temporarily changed to a room for three people, there will always be more and more witches in the future, and it is impossible to make do with it all the time. The superior living environment and all kinds of novel and comfortable experiences are also one of his strategies to retain witches, whether it is the luxury of the ancients or the modern sugar-coated cannonballism, a beautiful and comfortable life can always make people indulge in it.

"Three-tiered ...... Brick house?"

"It's not exactly a brick house," Roland smiled, "and it's supposed to be called a brick and concrete structure, and the pillars and beams are made of reinforced concrete, like human bones." This structure allows the house to be built higher, and it is no problem to add four or five floors in the future. ”

"Rebar...... Concrete?" Carl repeated with a confused expression.

"It's a mixture of cement, sand and gravel, with steel bars implanted in the middle to strengthen its flexural resistance," he says, "and of course, the exact amount of each ingredient needs to be rigorously tested, and if the configuration is successful, it is even stronger than natural bluestone." ”

Theoretically speaking, this kind of thing has a very large elastic space in quality, and it is also concrete, and the cement purchased in the countryside is configured by itself, and the metering configuration of the mixing plant is completely different. The same goes for rebar...... Some people build their own houses on their homesteads, even without pebbles, or with wire, bamboo instead of steel bars, Roland has seen several "country houses" rise from the ground when he stayed in the countryside.

And he plans to do the same, after all, it is only a three-story house, and no matter how much you cut corners, it will be difficult to collapse.

In addition, he hopes that through the construction of the witch's residential building, Carl will be able to master this perfect building material that can change shape at will, like artificial stone. As one of the development directions of the construction industry, concrete occupies almost half of the country. He was not proficient in architecture, but only learned the little bit he had learned from the countryside, so it was the right thing to do to broaden the stonemason's horizons and lead him to the right path.

"Uh...... Is this something for me to explore slowly?" he asked.

"No," Roland smiled slightly, "I can teach you this." (To be continued.) )
