Watching Urimu and Norwen walk out of the room, William took a charcoal pen from the pen holder on the table and a chapter of parchment from the drawer behind him, and began to conceive of his castle structure.

"Hmm...... Urn City ...... This is a good way to consume the enemy's forces and Yin people, there seem to be few such structures here, add it! William muttered.

Urn City, this is a kind of fortification that basically every unit above the county seat in the Celestial Empire will have, he can play a role in consuming the enemy's troops, as well as the role of surprise, Urn City is the first line of defense of a city.

"There should be shooting platforms protruding on all sides, and the arrow tower should not be missing......"

He was engrossed in his desk, drawing a diagram of the structure of his castle, his first castle, and the only castle for a long time, and he could not afford to be sloppy, it was a noble thing to live in.

"The length of the city wall...... Just a kilometer! ”

A thousand meters of city walls is not small here, and the length of the wall of Constantinople in his previous life seems to have been no more than ten kilometers, and it is still a world-famous castle.

And he is a small baron, it is good to be able to have a thousand-meter-long castle, that is, many viscounts, there are no castles, just like William has seen, the length of Viscount Winston's castle is only five hundred meters.

Even the Earl's Denlenburg is only 1,500 meters long, and if William's current number of troops is used, it is a bit reluctant to defend a thousand-meter-long wall.

But he firmly believes that the number of his troops will never be so small, and he will continue to expand and expand his army as soon as the population allows.

And his population growth rate is believed to not disappoint him, ten years later, his population will grow explosively, and in ten years, his population will be more and more.

Looking at the more and more perfect sketches of the castle, William couldn't help but nod with satisfaction, he really wanted a moat, but there was no big river in his territory, even if he dug a ditch, it couldn't be used as a moat.

This is a bit of a fly in the ointment, but William is not too disappointed, after all, the castle alone is a rather large project, and if you add the moat, then the time consumed will definitely not be short.

Truth be told, the construction of a castle is not a cheap job, and most of the nobles who own a castle have been taken from the enemy, or have been built many years ago, and have been improving it ever since.

And William's plan is that it will be completed in two years at most, and the amount of work will be large, the food and lodging of three or four thousand people, and the manufacture of various materials, that is not a small amount, and it will definitely not be less than forty or fifty thousand silver coins.

And William only had more than 60,000 silver coins left at this time, and the speed of making money could not keep up with the speed of spending money in any case, plus other things that William planned to build, the repair of various buildings, and even he wanted to make a waterwheel as a technology to increase agricultural production, and these are inseparable from the support of money.

For the first time, after William made vodka and resold war horses, he felt that he could not make ends meet and was short of money.

Thinking of this, William couldn't help but rub his eyebrows, he was really not used to worrying about money for a long time.

"Looks like it's time for other businesses to be on the agenda!" William picked up the charcoal on the table and said with a sigh.

"And this!" William put down the sketch of the castle and took out a piece of parchment from the back drawer, and since he had decided to use bricks as well, he was to design a brick kiln.

In fact, it is not difficult for him to burn bricks, now that he knows that kind of technology, all that remains is to design a brick kiln.

Soon, William got the design of the brick kiln, the scale is medium, it can accommodate two hundred people to work at the same time, and in the future, there will definitely be no fewer enemies using bricks in his territory, so he will simply make the scale larger now.

With the blueprint in his hand, William looked at the sun outside, and seeing that it was still early, he walked out of the study, called the two guards at the door, and walked to the stables to take out the war horse.

He was going to the village below the main fort of the manor, and found the villagers or the looters to build this brick kiln.

At this time, there were quite a few people in the manor, and after several population buys, the population of this village had exceeded before, and the village chief was also a high-ranking official of William.

The 3,000 people who have been resettled are just a few dozen meters outside the village, and at night they will enter the villagers' houses as families to take refuge from the cold, and as soon as the morning dawns, they will come out again.

Looking at the plundered population that was still idle, William went directly to the head of the village.

"Honorable Baron, allow me, this humble soul, to pay you the highest respect, and do you have any orders to command when you come here?" The village chief stood on the ground, bowed his head, and asked William in a tone that was about to be humbled into the dirt.

"Well, that's right, I have a building that you need to complete, but now you don't need to, you just need to command some idle refugees to complete it, and I'll leave this task to you, I hope to be able to see this complete building in two days, understand?"

William nodded, spoke to the village chief in a dignified tone, and handed him the blueprints in his hand.

"Yes, my lord, follow your orders, and you will definitely see this building in two days!" The village chief opened the parchment in his hand and glanced at it.

"Very well, you can go to Vidal for the materials needed for the construction, or mobilize them to collect them, and if you don't have anything to report, I'll go back!"

After arranging this, William rode back to the main castle.

It is his habit to travel on horseback, and at the same time many nobles are also the same, the reason is that the environment in such a village is harsh, and the feces, urine and sewage of people and animals will be thrown directly on the ground, so if you walk on foot, you may step on a team of disgusting things, so traveling on horseback is basically the choice of all nobles.

Even though William cleaned up his hygiene, so that his people were not allowed to defecate in the open, and at the same time cleaned up the livestock manure in time to become clean, it became his habit to travel on horseback.

When he returned to the manor, and dealt with some of the things that had piled up, and then stayed with Wella for a while, and talked to Lingsi for a while, he took off his noble robe, and lay down on the bed covered with felt, velvet, and linen, and looked comfortably at the ceiling lit by the oil lamp.

There was no good entertainment here, so the lords didn't have much choice but to make people and watch the boring knights, and the athletic tournament was not something that anyone could do, and it required too much money.

So this created the habit of the nobles to go to bed early if they had nothing to do, and William was no exception.

He was tired of seeing those knights, and before going to bed, he drank a glass of water, ate a mouthful of white bread, and then took off his strips and lay down in the quilt, and the whole room became very warm under the roasting of the fireplace, even if it was very easy to cause a fire, but the nobles were still so enthusiastic about the fireplace.
