Several workers carried the concrete in the animal skin bags to the hillside as ordered by Knight Colin.

Several people, led by Knight Collin, followed the steps of the workers to the top of the hill.

"It's a good ambush spot, and you're pretty discerning. Carolon looked around at the terrain and complimented.

"Hahaha, thank you Lord Carolin for your compliment, this is indeed a natural place!" Murphy laughed heartily twice, he was usually used to listening to lich-style dialogue, and he was ridiculed every day, and it was rare to hear a serious kind word.

The South Gate Pass is a hilly terrain, with a variety of hills of several hundred meters or so, and the road to the core of Remlos Fort from the south side is only a long and winding road, while the South Gate Pass is just blocked at the junction between the hills and the small plains, and the location is naturally dangerous, which is the main reason why Murphy decided to build a sniper fortress here.

However, in recent centuries, although there have been frequent territorial wars in the country, they have basically not expanded to the border areas, which means that their territory will border with the enemy country, so it has been safe.

Therefore, even though the location of the South Gate Pass is dangerous, the lords of successive generations have not built defensive fortresses or checkpoints here.

The hapless Murphy was thrown to Remlos Castle, which perfectly attracted the attention of the mob, intending to rob a royal bloodline for benefits.

Taking a step back and thinking about it, even if you can't get a ransom, killing it directly can have a huge impact on the royal family, and if you frustrate the morale of the aristocratic army, no matter how you choose, you won't lose, so why not?

The workers had already begun to move, transporting the proportionally adjusted concrete to the top of the cliff and placing it on a pump-like circle, yes, a mobile and high-tech circle made by Carolen.

The magic circle is activated, and the concrete placed on it is pumped to the part that needs to be poured, because it is a magic pump array, so the whole process is transparent, and the concrete seems to float into the air by itself, and then enters the predetermined template position, the problems that traditional pumping needs to worry about, there is no need to worry about now, this is the convenience of magic.

The speed of pumping with magic is very fast, and there is no need to worry about the blades getting stuck or blocking the pipe, because this tube is generated by activating the magic circle and urging the elemental power, which is not visible to the naked eye at all, unless it enters the spell casting state or the fighting state of fighting energy.

It's already April, and the snow has melted in Remlos Castle, which should have been the beginning of spring ploughing, and the peasants are busy in the fields, but now the whole north is in chaos because of a rebellion.

The concrete fort was built at a rapid pace, the overall shape was a bit like a cylinder, and a large opening was made in the face of the cliff, so that the shooters could shoot downward, and the shooters who were in ambush could evacuate at any time without fear of being intercepted.

The first fort took only a few hours to completely solidify, and the main work after that was to maintain, as time went on, the strength of the concrete that had been poured would become stronger and stronger, because its interior was constantly reacting, and Carolon also sprinkled some "catalytic" potion powder in these concretes, as well as some enchanted powder that strengthened the strength and reaction speed of the concrete, which further ensured the strength and stability of the fortress.

After all, he didn't study civil engineering in his previous life, and he didn't know much about civil engineering, he only knew the proportion of concrete and the pouring method, and it was already very good to be able to make such a fortress, anyway, he himself was very full.

"Your Highness, this, this, this is incredible!" Marshall's eyes widened when the template was removed, and Carolon next to him was still a little surprised even if he had tested the material of this material during the experiment.

Marshall took a few steps forward excitedly, his hand trembling and stroking the walls of the fortress, feeling the roughness of the concrete, his eyes full of shock, and his heart constantly calculating the value of this thing.

"Your Highness, we're going to get rich!" Marshall turned his head to look at Murphy, his eyes reddening and both eyes turning into the shape of Kinnaso.

"Comrade Marshall, I understand what you are thinking, these concrete are not intended to be sold to the outside world at present, at least not for half a year, because now it is like steel, saltpeter and sulfuric acid, which is our strategic material. Murphy rubbed his temples and gagged Marshall's mouth before he could say anything.

"Comrade?" Marshall said that he didn't quite understand this new word made up by His Highness, but it should be a good name, after all, His Highness is not scolding himself now.

"The reason why I want to ask you for help is not because I want to sell this thing, but after this war, I want you to mobilize the people to carry out large-scale construction, this concrete, and these steel bars, cement and concrete, are our weapons for this large-scale construction!"

Murphy looked forward to the future and said impassionedly.

"It is foreseeable that with the construction value of these concretes, Fort Remlos will have a tall and impregnable wall, and the majestic castle will stand in the center of the city!" Marshall thought of the future, and his heart was infinitely excited, and he couldn't help but praise Murphy.

"No, Marshall, you're wrong again. Murphy shook his head and denied Marshall's claims.

"In the near future, I will tear down the walls of Remlos Castle. ”。

"What?!"

The wind in late spring was very warm, blowing away the snow that stretched for thousands of miles in the north, but it made Marshall fall into an ice cave at this time, and he could not have imagined that His Royal Highness the Prince would have the idea of demolishing the city wall.
