Duke and Michelangelo discussed for a long time in the study, although the two are absolutely opposite in terms of faith, but I have to say that in architecture, the two people have a feeling of sympathy for each other, and they both sigh that the other party is a wizard of architecture!

Needless to say, Duke is a civil engineer in his other world, and his vision and level far exceed this world's level. However, many of Michelangelo's concepts and artistic concepts also made Duke feel a deep impress, worthy of being called the three masters of the Renaissance in later generations, and even created the essence of art in an era, and indeed has a vision beyond the times.

To Duke's disappointment, however, the new way he was looking for did not materialize, and the world was still the same as in the Middle Ages, where high-quality buildings were still mined from the mountains, slowly carved into stone strips, and finally cemented with earth-made concrete.

Although this kind of masonry structure is reliable, it takes too long, even if tens of thousands of people build it at the same time, and want to build a new city with a scale of 100,000 people, although there is no need to wait for the bones to be cold, but at least a few years or even ten years are also required, and Duke can't afford to wait.

Although Storm Castle has accumulated a little wealth due to porcelain sales during this time, it can't afford this kind of expenditure, and if it really has to be built according to the world's methods, it will soon fall into the same financial crisis situation as before.

Duke thought about it again and again, and wanted to build a city in about a year, without relying on any large construction machinery, and there was no disadvantage in quality, and he could only rely on the modern construction method of reinforced concrete. There is no shortage of steel bars in Storm Fort, and it is not difficult to fire red bricks in the Middle Ages, the only difficult point is concrete.

Before the advent of Polante cement in the Age of Discovery, the Romans had been using volcanic ash to make concrete-like binders. Because when the volcanic ash is mixed with lime and water, it can react to form hydrate with the ability to gel hydrate.

In fact, Saint-Michel also has volcanic ash, but it is far from enough to build a city, and the hydration of volcanic ash is not enough in terms of hardness, but Duke knows the horror of the ice demon, not to mention the terrifying magic attack, as well as possible firearm attacks in the future.

Because Duke already knew from Copperbeard that the Dwarves had not only developed steam engines, but also professional firearms warriors such as Dwarven musketeers, and even more mysterious goblin engineers, who had also developed hot weapons such as bombs or cannons.

These things are beyond Duke's expectations, although there is no trace of hot weapons at present, and even the bronze beard of fellow dwarves does not know how far they have reached, but Duke can't help but take precautions, because no one in this world knows the horror of firearms better than him!

Therefore, the construction of reinforced concrete structures is imperative, but fortunately, Duke, as a civil engineer in his last life, is no stranger to cement production, and the production difficulty is not high.

In particular, the early Polante cement was actually calcined with limestone and clay, and then ground into powder, which was the original cement, but Duke, as a civil engineer, finally encountered something that the bank knew very well, how could it be possible to make this kind of early low-end goods? At least it must reach the level of Yasputin's improvement in the 18th century, that is, cement close to modern standards.

In fact, even if it is modern cement, to put it bluntly, it is "two grinding and one burning", mining limestone is ground and then mixed with clay according to the analogy to become raw meal, and then calcined mature material, and finally gypsum and other mixed materials are added to grind into powder, which is the final cement.

There is no problem with mining Storm Fort, Mont Saint-Michel has limestone, and the grinding is now with the addition of hydraulic machinery, the efficiency and strength are almost 100 times better than that of manual labor, and it is not a problem, as long as you dig one more canal and get a few more hydraulic grinders.

The only thing that is a little difficult is calcination, but in fact, this is not a big problem, because the requirements for cement calcination are far less high than those of porcelain and steelmaking, and it can almost be used. Of course, the only way to do this is to use the strategy of a magic blast furnace, using a witch or a magician to control the temperature with a magic array.

However, now that Storm Castle is in short supply of magical talents, it is not yet extravagant enough to let them burn cement, so they can only make do with it.

The plan has been decided, and the entire Storm Castle has begun to operate and execute, in fact, for the adhesive of cement, people in this era don't need to worry about everything except calcination, because this world has long had similar products.

Therefore, the progress of cement is even faster than he expected, and in just two days, the prototype of the cement factory has been built, waiting for the new cement grinder to be successfully assembled and ready for production.

In the past two days, Duke has been almost sleepless, and Michelangelo and Michelangelo have drawn a sketch of the capital construction of Storm City, and after waiting for the cement production to be successful, they can directly follow the drawings for construction. One can imagine the day when Storm City is built, a city of reinforced concrete will appear in the Magical Middle Ages, and what a spectacular scene it will be.

Seeing Michelangelo away, Duke's eyes were bloodshot, but he kept calling for Casmeel to come over.

Because from the discussion in these two days, Duke deeply felt that Michelangelo was an architectural genius, but this guy was also an unusually devout believer, and he was extremely enthusiastic about mission, even when designing drawings, he had nothing to preach the glory and greatness of the Lord to Duke.

If it weren't for seeing this guy's talent, Duke would have wanted Alan to give him a few old punches at that time, so that he could understand the fact that fists are harder than mouths! It also reminded Duke of this incident, if this guy went to preach to the homeless, saying that these are all things given by the Lord, thanking God for His grace, etc., then Duke would simply vomit blood, and someone would have captured the public opinion propaganda position in his lair!

So Duke gave Cassmail only one task, to brainwash Michelangelo as much as he could, so that he could understand that science is the truth. If this can't be done, at least Michelangelo's mission must be stopped, after all, Kasmai still has the identity of a Bishop of Storm Castle, and this is his diocese and territory!

After Kasmai left, Duke sat down in his seat, his eyes closed and full of exhaustion, but at this time a long-lost female voice came to his ears.

"Little Duke, although hard work is a good thing, if it damages the body, it will be worth the loss. ”

Hearing this voice, Duke knew who was coming, so he replied angrily: "Sister, I am very tired now and want to rest early, if you have anything to say, you can say it directly." ”

Hera looked unhappy when she heard this, and walked up to Duke and put her hand on his shoulder: "My little Duke is really a lot haggard, then I won't delay your time." During this time, through my investigations, I have come to know who we were found in Andorra la Vella. ”
