"Your Highness, how high and wide do you plan to build this city wall?"

"At least fifteen feet high and six feet wide, enough for four people to walk side by side," Roland nodded inwardly, thinking that the professionals were different. They first asked about the technical parameters before determining the construction plan.

"Then it will need a ditch one person deep to stabilize the upper wall. And if the top is six feet wide and the wall is fifteen feet high, the bottom width should be at least doubled," Karl quickly replied, "This alone will consume a lot of manpower just to dig the ditch. Your Highness, if you can give me one hundred and fifty people, I should be able to dig this ditch before the Months of the Evil."

"A ditch can't stop the Evil Beasts," Roland said noncommittally.

"That's right. If the upper part of the wall is built with stones, it will take three years. If it's only to block the Evil Beasts, the wall doesn't need to be built so high, about twelve feet is enough, and the width can also be reduced by a third, with the bottom reduced to six feet. Digging the ditch and building the wall at the same time, increasing the number of people by two hundred... In this way, I can complete it before the Months of the Evil arrive next year."

Karl paused, then continued, "Please forgive my bluntness, Your Highness, now is not a good time to start construction. If the wall is not built in time, even if the ditch is dug, it will lose its original function after being soaked in rain and snow throughout the winter. Instead, you will have to spend more time and manpower to clean the softened ditch and deepen the excavation again."

"If it's built twelve feet high and four feet wide as you said, how long will it take to dig the ditch?"

"It should take a month and a half," Karl replied.

"Then let's do it according to this plan, digging the ditch and building at the same time, and complete it before the Months of the Evil arrive." Roland waved his hand, interrupting what Karl wanted to say, "I know what you're worried about, take a look at this first, the latest work from the Graycastle Alchemy Workshop."

He naturally didn't have time to glue stone bricks again for the stonemason to see, he just dragged out the two previously glued ones to show them. Fortunately, almost no one dared to question the prince, when Karl heard that this alchemical binder called cement could be transformed from liquid to solid between day and night and produce extremely high adhesion, an incredible look of shock appeared on his face.

Having dedicated the first half of his life to the Stonemasons' Guild, he naturally realized how great this invention was. In addition to bonding stones, more importantly, it can also shape any form at will. Isn't this equivalent to having stones of any shape without secondary cutting and grinding? By abandoning the time-consuming and laborious processing stage, the construction speed of any building will be brought to a new level. This alone is enough to be exciting!

Roland looked at the other party's expression with satisfaction and asked again, "What do you think, are three months enough?"

Karl. Vanbert's voice trembled slightly, "If what you said is true, no no, I mean... if the alchemists' workshop's description of this thing is correct, I... I am willing to try."

"Very good, I will have someone write a detailed manual for you on how to use the cement, and if you need anything else, talk to my minister's assistant," Roland said with a smile, "Mr. Karl, now you are a member of the Administrative Office."

Seeing Nana Wa herself was the next afternoon. The little girl looked at Anna blankly, clutching the corner of her clothes and finally squeezing out a sentence, "Am I... dead?"

The first time he saw her, Roland had to admit that the power of witches not only endowed them with magical abilities, but also changed their appearance and temperament to some extent. She and Anna were completely different types, but both contained a unique charm. This feeling had nothing to do with age or life status, even when Anna was waiting for death in prison, the light she emitted was still undiminished. After searching through his entire memory, he had never had such a feeling, whether it was a street prostitute or a well-bred noble xiaojie in Graycastle. If he had to describe it, putting them together with witches was like colored figures appearing in black and white photos.

Karl. Vanbert, who brought her, retreated tactfully, leaving only Roland, Anna and Nana Wa in the palace garden.

"You're not dead, and Anna is alive and well," Roland said, suppressing his smile, "I am Fourth Prince Roland Wimbledon, and you are—"

"I am Nana Wa. Pine," the little girl heard that she was not dead, and her expression came back to life. She ran straight to Anna and chatted with her, completely ignoring the identity of Roland, the Prince of Graycastle. Roland naturally wouldn't bother with a little girl who was only fourteen or fifteen years old. He sat down by the round table, poured himself some wheat beer, and admired the "daily life" of the two witches.

Anna was obviously a little uncomfortable with the other party's familiarity, Nana Wa would say a dozen sentences before she would respond. Come to think of it, Anna was only seventeen years old, but she already had the feeling of an older sister. Roland couldn't help but wonder, how outstanding would she become when she grew up?

It wasn't until Nana Wa's speech gradually slowed down that he coughed twice and asked, "Pine xiaojie, I heard from your teacher that you have awakened as a witch?"

Compared to what most people said was "falling" into a witch, Roland preferred the word awakening. He wouldn't naively think that all witches were pure and flawless white paper, people with malicious intent would only cause greater destruction after gaining power. This is just like a weapon, it can create violence, and it can also resist violence, the key is who is holding the weapon. Perhaps the witch tusha incidents publicized by the Church are based on facts, but it is too unfair to take this as evidence of the witch group's crimes.

Nana Wa's expression froze, and she asked in a low voice, "Will you hang me?"

"No, of course not, those who go to the gallows are heinous criminals. You are not, and Anna xiaojie is not, so don't worry about this."

She took a breath and nodded, "I'm not sure either... My teacher said that witches have demonic power after being tempted by devils, but, but I haven't seen devils?"

"When did you find yourself different?"

"About a week ago," Nana Wa muttered, "I saw a little bird that broke its leg, and I wanted to help it. Then... I felt something running out of my hand."

"Something ran out?" Roland asked, "Then what?"

"Um... It suddenly surrounded the little bird, like a sticky water," Nana Wa tilted her head and recalled, "Then the little bird's leg was healed."

Could her power be healing type? Roland's heart thumped violently, he knew very well what this ability meant - in an era without antibiotics, without modern medicine, and when wounds and infections could easily lead to death, the ability to quickly heal wounds was simply equivalent to having an extra life. This ability doesn't do much to promote the progress of the entire civilization, but it is amazingly meaningful to individual lives.

He immediately walked to the door and asked the knight guarding outside to find a live chicken. If he could prove that what she said was true, he might be able to use this to change the situation of witches being mercilessly pohài in Border Town.
