After some explanation by Martin, Karna finally understood where Lorrainburg's success was.

Of course, Lorrainburg developed a cutting-edge building material, cement.

A small amount of cement, which does not help at all.

Lorraine was able to build a fortress all the way to the 'Great Wall' to Gzanti, relying on a set of production systems that could be done to the extreme under the productive forces of the feudal era.

First of all, Martin looted the carpenters, stonemasons, and blacksmiths of the entire kingdom in disguise. These craftsmen, together with their apprentices, numbered as much as 4,000, and this was without their families.

Not only did Martin pay twice as much as the wages of the other lords, but he also ransomed the artisans who belonged to the other lords to become freedmen.

Martin promised them a year later that when the civilian quarters of Lorrainburg were built, they were allowed to bring their families and give each family a two-story house of 1,000 square feet (100 square meters).

With all the perks that come with it, Karna already sounds like a headache.

Although Rick's empire is large, craftsmen are still in short supply and are needed everywhere. Often the rebels or something, if they can't take away the craftsmen, they have to kill them, and it won't be cheap Karna.

Rick City is large, but there are never so many places to house such a number of artisans.

The second is capacity and transportation

For such a large project, the amount of cement consumed is already measured in 10,000 tons. If it weren't for the volcanic ash mine next to Lorrainburg, mixing and transporting it alone would have been a big problem.

Once the cement is wet, it will form a hard lump and cannot be used.

The transportation of this era is really hehe.

And then there's engineering.

Originally, Bakaria's engineering skills were definitely worse than the Empire, but there was Martin, a traverser, who was sacrificed in college. Many of them are secrets and skills that stonemasons and craftsmen need to ponder for half a lifetime, and even only the master will teach, which is normal in Martin's eyes.

Then there are: multi-pulley booms, sleeper rail carriages, and even a shovel whose size and length are rigorously calculated.

These seemingly inconspicuous inventions, made on the principles of modern mechanics, are the secret of such an efficient construction in Lorrainburg.

In the end, it's someone cheating. Using the [Heavenly Lock] to drive piles under the water is simply a unique skill that only Martin can do.

Even if Martin taught Karna a full set of reinforced concrete gameplay and provided enough cement and rebar, she would not be able to build a bridge across the river in Rick City on the south bank of the Rick River, as she thought, so that the Lopez family's troops could directly kill the north bank.

"Hey, you're just letting me understand that I, Rick, can't handle it. Let me know that it is difficult to retreat?" Karna said in a complaining tone, she stood up, crossed her waist, and looked like she was leaving: "In that case, what am I here for? I'll go." ”

Karna...... Has anyone told you that your acting skills are terrible......" Martin choked Karna half to death with a single sentence.

The Empress-elect went out on the spot, and a pink fist went from small to big in Martin's vision......

Hold the grass!What a fight!?

Hell, "100% empty-handed white blade" is launched!

Karna's agility stat seems to be above him, wow!

Just a little bit, Martin is about to turn into a panda eye.

Of course, the old general Ram grabbed her and said, "Wait! Don't be impulsive!"

"Hell, I'm going to beat this bastard to death! How dare I say I'm bad at acting! It's an insult to Rick's Empire! Bastard, I'm going to duel with you! Can't you just be like a man?"

Martin glanced at Karna's trembling twin peaks, and then at the beautiful legs that were clamped without a slit, and said, "Alas, if you understand what kind of man I am, you will regret it."

Garr, who was standing beside Martin, did not squint and counted intently how many ants there were on the ground.

Martin bared his teeth, and then threw out his plan in a dignified and shameful manner.

After listening, General Ram was dumbfounded, Karna was so angry that her teeth were itching, and her good-looking golden eyebrows jumped wildly, deducing what Yan Yi was.

"Yo, my friend, you mean, let the Lopez family send 5,000 elite private soldiers, not a single copper coin, bring their own grain and grass to help you capture the entire wasteland, and give you another 1 million gold coins. In the end, you're just going to help me build a bridge in the southeast of the wasteland, near the former Duchy of Ravenna?"

For a second, Old Ram almost wanted to let go of Her Majesty the Queen-to-be and let this girl with a lot of force beat Martin and his daughter.

"Whew!" Martin sighed, "I think you'd better come and see my bridge for yourself and think about whether it's worth it." ”

The two didn't say a word, followed Martin, and came to the bridge construction site surrounded by personal guards.

Going out from the City Lord's Mansion was already a grand scene of traffic.

"Come and see! The most gorgeous lacquerware in the Rick Empire, only three silver coins, a large amount is preferred!"

"Do you want to take an adventure? Do you want to join the great Lords of Lorraine's crusade in the wasteland? What are you waiting for? The finest silver scale breastplate, 5 gold each. ”

Even though they were passing through a traffic artery where hawking was prohibited, Karna and the others could still hear the cries from the western market, as well as the noise characteristic of the market.

"The west market is a business area, and the northwest is an industrial area. To the east of the avenue are residential areas and vegetable and meat markets. Riding a horse, Martin casually introduced.

"Any idea what I'm thinking right now?" Karna said.

"Huh?"

"Tie you back and take me to my staff office and make me Minister of the Interior. Karna said angrily.

Martin stuck out his tongue and shook his right index finger in a shudder: "You can't afford to ask for me, the Home Secretary." Besides, you're no match for me!"

Karna exploded like a cat on the spot, and casually pulled out her war hammer and swung it: "You try it again!?

"Your Highness, don't be impulsive!" Ram and the other guards hurriedly pulled Karna. After all, this is the street!

The old general smiled bitterly, 99% of the time, his own precious queen was simply wise and martial, why did he suddenly become so immature when he met Martin. Only at such times did she look more like a fifteen-year-old girl, alas......

Of course, the guards on Martin's side knew that the other party was joking, and they didn't squint - I couldn't see it! I couldn't see anything!

When they came to the construction site at Qiaotou, Karna and others were even more emotional.

Two huge bridgeheads are like two giants, majestically guarding this miraculous bridge.

Under the watchful eye of the soldiers above the fort, workers set up horse-drawn wagons and carried huge steel frames made into long strips, as well as bales of cement in double sacks, to the end of the bridge deck.
