On the third day, Bruce looked at the flat planks, and asked the blacksmith father and son to lead the serfs to make one end of the plank into a wedge shape, and the other plank into a concave part, and at first the serfs only mechanically did what Bruce ordered, but only the elder Warren noticed Bruce's intentions.

"My lord, what are you doing, why did you split the good wood into a gap?" As Eve passed by, she asked Elder Warren in confusion.

"This is not simple, if I am not mistaken, this is the technology of the Pumen Empire." Elder Warren looked at the wood that had been processed into different shapes and whispered to Eve.

"How is that possible?" Eve shook her head in disbelief, the Pumen Empire was a powerful slave empire that once unified the entire Dias continent, and they had many technologies that would astonish people now, such as the huge circular Colosseum in the Holy City, and the magnificent elevated aqueduct.

"In the Imperial Library, there are some books on the affairs of the Pumen Empire, I remember very clearly, there is a passage in it that records that the soldiers of the Pumen Empire would quickly build fortifications with wood during the march, I didn't understand how they were so fast before, but now I seem to understand a little." Elder Warren said to Eve on crutches.

"You've been to the Imperial Library?" Eve's focus is a little different, although the Imperial Library is named to belong to the Empire, it is in fact guarded by the Church, which believes that there are many extremely dangerous ideas and knowledge in it, and it cannot be entered without the permission of the Pope.

"Hahaha." Elder Warren smiled, he didn't answer Eve's question, just focused on Bruce at work, the little lord was full of mystery to Warren at this time.

One end of the wood was processed according to Bruce's instructions, and Bruce taught the serfs to use a ruler to take precise measurements while checking their work until every plank was qualified.

"Now put the planks together." Bruce commanded the serfs.

The serfs picked up the timber of the first section of the wedge and put it on the concave section of the timber, they picked up the mallet in their hands and knocked it down together, only to hear the sound of ping-pong pong endlessly, and the timber was perfectly assembled together.

"Awesome." Eve looked at Bruce's assembled timber and couldn't help but admire.

Most of the wood stockades in this era are cut into logs with sharp ends at both ends, and then inserted into the ground one by one, which is a great waste of wood, and the land of Grington is barren and lacks wood, if you use this method, to build a wooden fortress that is not strong, I am afraid it will cost the whole small forest, but this kind of assembled wood is different, the wood that connects seamlessly with each other forms a wooden wall, but there is still a small problem, that is, the wooden wall is not strong.

"Is this magic too?" Monica hid in the lord's house, leaning against the window and watching cautiously for fear of being discovered.

"What kind of magic is this, it's just a craftsman's skill." Mavis bit down on the apple, and she said with some unconvinced.

"But it's amazing, those boards are like they grow like that." Monica was amazed by the beauty and purpose of the boarding.

"Tsk, this little lord has some skills, maybe he can really help you find a way to restore your appearance." Mavis wasn't sour this time, she said thoughtfully.

Bruce looked at the assembled planks, nodded with satisfaction, and then ordered the serfs to erect these combined planks in the trench, everyone felt inexplicable, they originally thought that Bruce was going to use wooden walls to build the outer wall, but what is the use of this kind of hollow wooden wall with a gap of two meters in between?

"My lord, if you want to build a wooden wall, you should have told me earlier, I am more experienced in this area." Stukov walked up to Bruce and said to him.

"Build a wooden wall?" Bruce smiled contemptuously, was the wooden wall as strong as the thing he was about to build?

While Bruce was worried about James and was trying to start building defenses, James didn't bother to pay attention to Bruce at this time, because Duke Bermessi was about to visit Rock Manor, which was a once-in-a-lifetime opportunity for James.

"How's my clothes?" James kept sorting out his aristocratic clothes, which were made by a tailor invited from the big towns of the Duchy of Bemessi, light blue fine linen, and the edges of the clothes were also bordered with expensive yellow silk, the glittering silk made James full of nobility, this dress was worth almost ten years of territorial taxes, which made James very proud.

"Perfect, Lord Baron." The attendant beside James immediately said flatteringly.

"I have heard that the Duke has ten garments made entirely of silk, and I can only trim them with silk." James bit his lip and said with some discouragement and envy.

Sir Wayne stood behind James, he frowned slightly, in order to appease Duke Bemessey, James collected taxes in the territory three years in advance, which has made the serfs in the territory complain, but because of the failure to remove the title of Bruce, James did not give him a good face, which made Sir Wayne not know how to persuade him.

"Here they are."

Suddenly, a servant of Locke Manor hurried to the gate, and he pointed behind him excitedly and said to James.

"Great, cheer me up." James straightened his back, and his feet dragged the toes of his shoes four or five inches long, the kind of court nobles wore on the advice of his tailors.

"Gotta gotta gotta ~~." At the same time as the servant reported to James, there was a sound of horses' hooves from the forest path outside Locke Manor, and soon the people in the manor saw two knights wearing iron helmets holding flags, the Duke of Bemessy's flag coat of arms was a yellow and red fish scale checker, the simpler the pattern, the more it indicated the antiquity of the duke's lineage, but the flag in the hands of the other knight was a red tower pattern, which represented the other lineage of the duke, which was from the side line of the royal family.

It was not just the illustrious family coat of arms that James envied, but the blue ribbon wrapped around the flagpole, a symbol that only the Duke of Bemessi could use, one of the ten dukes who wielded great power in the Empire.

"Boom~~."

As the leading knights passed, the roar of horses' hooves and carriages was heard behind them, and a team of a hundred men appeared at the edge of the forest, and a smile appeared on James' face, and he finally looked forward to the Duke of Bemessi.

"So many people." However, Earl Wayne, who was behind James, frowned, the Duke brought more than a hundred retinues, which cost a lot of food and resources every day, although the vassals were obliged to bear the hospitality of the lord when he inspected the territory, but this was also a very heavy burden.
