Chapter 33 Improved Processes

Regarding the choice of the castle, Ronan finally chose Leo's plan after thinking about it, that is, he gave up the protection of the double city wall and chose a comfortable living castle.

Because this thing does not have a very good defensive effect, but it will make people living in the castle feel cramped and depressed.

The initial prosperity of the castle stemmed from the political division of the nobles in the major territories, which led to wars between them at any time.Therefore, in order to ensure personal and property safety, the lords began to build castles, the most reliable defensive buildings at that time.

Its military significance far exceeds the significance of life as a residence.

But in the previous life, with the appearance of large-caliber artillery, the original impregnable defense of the castle collapsed, coupled with the economic development caused by the prosperity of maritime trade, people's pursuit began to increase, and the castle quickly fell into decline.

Although gunpowder has not yet developed to that point in this world, the extraordinary existence also doomed the defense of the castle to be lower than expected.

With a flap of bat wings, the vampire can easily leap over the city wall.

Ronan has his own means to ensure safety, there is no need to waste a lot of time and materials building the castle into a military fortress.

After determining the direction of the construction of the castle, the construction of this new town officially started.

A large number of laborers began to travel between here and the nearby stone mountain roads to carry the stone materials needed for construction. The previous generation of Baron Exeter was stimulated by the iron ore business in Iron Stone Territory. He once wanted to find mine veins in Coldwind Territory, so he went Several excavations were made in the mountainous terrain, but all of them were disappointing.

Up to now, the stones excavated from those rocky mountains are just convenient for Ronan's construction.

The craftsmen hold the architectural drawings in their hands, constantly planning the layout of the town, and in the distance, are the daily drills of the soldiers and the management of personnel work.

Ronan is sitting next to a newly dug kiln at the moment, watching the masons burn the stone.

"My lord, why are you here?" Leo, the leader of the artisans, looked at him curiously, wondering why the lord came here.

"What are you doing?"

"We are currently firing the mortar mud needed to pile up the bricks and stones, which can make the bricks and stones coagulate with each other and make the building stronger."

Because he was worried that the lord would not understand, Leo explained in the most straightforward words possible.

Has cement been produced in this era?Ronan's eyes lit up.

He began to observe their movements curiously.

It just doesn't feel right the more I look at it.

The stone was simply smashed into the size of a fist and put into the kiln without further crushing.

Then the masons added a lot of sand and broken bricks to the interior, and started to light firewood to heat the kiln.

Wait, it’s fine if you don’t add iron powder, but what about clay?

And just burning wood like this, the temperature inside the kiln is even 800 degrees Celsius, right?
If the temperature is not enough, the sintering of limestone is not good, and the product must not be full of impurities.

"Everyone stop." Ronan called to stop their work, looking at the puzzled eyes of the craftsmen, he didn't explain much.

"Change all the processes here. After the stone is further crushed, use a stone mortar to continue crushing. Then I will have someone dig clay from the river and bring it back. After you grind it according to the ratio of stone to clay, add iron ore The stone powder is refired."

As the lord, Ronan has the absolute right to say what he says here.

After the order was given, everyone began to act according to his order, whether they understood it or not.

"In addition, replace the firewood with coal as much as possible, and ask the carpenter to come over and make a blower tool. I told him the specific idea, and let people take turns to blow the wind."

The masons of this era have indeed begun to explore cement.

But the main ingredient is lime, volcanic ash plus sand, and broken bricks and stones are used instead of volcanic ash.

The biggest difference from genuine cement is the lack of clay, which also leads to insufficient hardening speed and hardness of the finished product.

Not to mention that low temperature leads to poor sintering of limestone, and quicklime is doped with a large amount of calcium carbonate.

The formula currently used by Ronan is the original version of Portland cement. Although it is far from modern cement due to the technological gap, it is completely sufficient in this era.

The only trouble is that in another month, the cold wind collar will enter winter in full swing.

When the low temperature causes the cement to coagulate, the internal liquid phase water solidifies into ice, which weakens the hydration of the cement and affects the strength of the finished product.

However, this is not impossible to solve. On the one hand, the construction speed is accelerated, and sodium chloride is added to the cement as an antifreeze agent.

On the other hand, stones and river sand can be added to the cement as aggregate to form concrete, and then concrete prefabricated parts can be prepared in advance with concrete and iron rods.

Combined with a human-powered crane made of a pulley block, at least the outline of the castle can be basically completed in winter.

The only problem is the consumption of steel, which will lead to a rapid increase in cost, but after all, it is the castle where I live, so it is completely acceptable for safety.

After letting the craftsmen resume work according to their own procedures, Ronan did not continue to stay here.

He left the crowded construction site and came to a dead tree alone.

Following his call, black dots began to appear in the distant sky, converging towards him from all directions.

There is no doubt that they are Ronan's crows, but this time, these crows have guests under their paws.

"Snow rabbit, wolf cub, fox, um, what's this, mouse?"

Ronan carefully looked at the small animals caught by the crow one by one. They all had wounds on their bodies, and shivered under the crow's claws.

His order to the crows was to capture small animals that could dig holes.

In his next plan, the crow will look for mountains in the sky where there may be mineral veins, and he also needs a prospector who goes deep underground for field investigation.

It's just that the results brought back made him a little dissatisfied.

Speaking of digging holes, Ronan immediately thought of pangolins, but that thing seems to live in the subtropical zone, not here.

Putting the animals aside in disgust, Ronan finally stopped in front of the mouse.

After looking carefully, he found the difference. This mouse had a big and flat head, silver-gray back hair, short and strong limbs, and the most important thing was that the front paws were particularly developed, and the third toe obviously grew a section.

"This is the mole?" Ronan's disgust disappeared instantly, and he took out a bottle of healing potion and drank it to heal the wound on the mole.

Then he put his finger on the mole's head, using spiritual projection to mark it.

Marking costs a quarter of his mana, and the mole can hold up to 2 of his mana.

【Mount Enhancement】

[sharp]

The mole's thick limbs tensed instantly, and the bulging muscles showed a strong beauty.

And the front end of its toes and claws faintly revealed a sharp edge.

Under Ronan's control, the mole easily dug up the ground and continued to dig deep underground.
