Lord: Marry the villain's daughter at the beginning?

Gray-collar workers' research on cement and gunpowder gradually got on the right track, especially cement, which directly accelerated the development of gray-collar workers. Many of the original tents were dismantled and people began to build new houses.

And next, Linde plans to start researching steelmaking.

This is a big job, but because Gray White Collar has not found iron ore yet, Linde has not put this item on daily routine before. Now, Linde plans to see how this world makes steel.

As long as steel can be produced in the territory, then with the addition of hydraulic forging hammers, future military needs will definitely be met.

The craftsmen in the territory are now mainly those from the Lars family who followed Lena to Gray Collar.

There are even many low-level professionals among them.

The place where steel is produced nowadays is more like a blacksmith shop than a steel mill.

In the beginning, there wasn't even a blacksmith shop, and it was Lind who assigned work to these craftsmen, although the work content was limited to repairing tools for the people every day.

Hearing today that the lord was going to have jet lag, these craftsmen were gearing up to perform well. After all, when the lord had something to do, he would really spend money, although it was all the Lars family's money.

But after the craftsmen demonstrated their steelmaking method, the lord seemed to be out of shape. After a brief inspection, he left the steel plant.

The old craftsman, who had originally thought that the lord would propose all kinds of fantastic machines and improvement methods like he had done to other craftsmen before, stroked his beard and reflected on whether he had done something wrong and made the lord unhappy. Otherwise, why did he feel that the lord treated him differently?

Linde returned to the tent and began to walk around in circles. He kept flipping through the introductory manual on rune magic circles in his hand and began to study it according to the original owner's memory.

It was too exaggerated. Although Lind had always given the world a little shock from his past life, this time it was the twisted technology tree of this world that gave Lind a little magical shock.

Lind had anticipated that there were many ways to improve the steelmaking technology in this world, such as blast furnace steelmaking. He had read so many time-travel novels that even if he couldn't do it, he could at least talk about it and inspire these craftsmen. However, he didn't expect that this world would directly come up with a way to break all methods with one force.

The temperature is not high enough? The heating is too slow? Impurities are easily generated?

Create a burning magic circle, and a few first- and second-level rune masters can directly use the rune magic circle to increase the temperature and violently solve all problems.

Of course, it is easier said than done. The rune magic circle can only be controlled by a rune master who has learned runes. The rune master himself is also a professional, not an ordinary person. Moreover, the rune magic circle requires constant fine-tuning and maintenance, and the cost is not low.

It can basically only be used for steelmaking and has no practical significance.

But this still gave Linde a little shock of the other world.

There was even a moment when Lind doubted whether everything he did was really meaningful, and whether there was other magic in the world that could perfectly replace his plan.

For example, have cement and gunpowder already had superior substitutes?

Judging from Reina's reaction, there shouldn't be any, but that was Reina after all. Linde, who was worried, went to find Isa again. After asking her in detail, he felt a little relieved.

Afterwards, Linde took Lena into the Giant God Mountains again.

Because today is the day for experimenting with gunpowder mining.

Although Reina had been hunting and playing in the mountains before building the hydraulic forge, she was not idle. There were still many mineral deposits in the Giant God Mountains. Linde now came to the corundum vein that Reina had just discovered not long ago.

Although the scale is not large, to be honest, Linde's main purpose of mining now is just to practice mining for gunpowder.

There are many mineral deposits in the Giant God Mountains, but because the location is relatively remote and the transportation costs are high, they have never been effectively developed.

In addition, the Surd region north of the Northern Snow Territory not only has higher quality ore, but also more convenient transportation and well-connected roads. No one would be willing to come to the Giant God Mountains and spend a higher cost to mine.

Especially when the elves on the other side of the mountains would jump out from time to time to ask for a piece of the pie.

Moreover, with the overall weakening of the Capetian Kingdom and the increasingly extravagant and dissolute lifestyle of the upper nobles, fewer and fewer professionals are willing to come to this remote corner and work hard to use their magic power to help the nobles mine every day.

After instructing a craftsman to use a chisel to chisel a large hole at the designated location, Lind ordered people to put the explosives in, and then stepped back several dozen meters to direct the lighting of the fuse.

Because no craftsman dared to take on this job at first, Susan, who was beside Reina, came to the lead impatiently.

Susan's understanding of the power of these explosives was only at the level of the firecrackers that blew up an iron pot at the beginning. She didn't find it scary at all. She snapped her fingers and the fuse began to burn. Then she posed, waved her cloak, and walked towards the bunker where Lena was.

boom!

A powerful gust of wind swept in, like an angry dragon roaring past, shaking the mountain so that rocks flew everywhere, and deafening explosions echoed among the mountains.

The defenseless Susan was thrown forward by the thrust of the explosion, and the defensive runes on her armor immediately determined that she was under attack and began to operate at full capacity.

"Protect the eldest lady!"

The knights around Reina instantly raised their shields and formed a formation. The explosion was beyond their understanding. They thought it was the enemies of the Lars family attacking.

As the flickering flames in the smoke and dust died out, a messy scene came into view: the rocks were blown to pieces and huge blocks of rock collapsed like a fortress.

Lind looked at the stunned Susan and the knights who were facing a formidable enemy with satisfaction. It seemed that his previous worries were unnecessary. Although there were many things in this world that were beyond his cognition, it seemed that gunpowder was still an invention far beyond this world.

"Record the amount used in this explosion, and the effect of mining."

After reminding the stunned craftsmen behind him, Lind began to observe the explosion scene.

"These gravels are also collected and can be used as building materials with cement, but remember to remind the workers to sort them out first."

Looking at the knights who were still on high alert, Lind just smiled slightly. After looking around, the knights awkwardly put down their shields.

But Reina, who was supposed to be chattering and asking how Linde did it, was now stroking her chin and thinking under the protection of the knights.

"brother."

Reina came to Linde excitedly, but did not show the shocked expression that Linde expected. Reina's mind started to work again.

"Do you think this so-called explosive can be launched using magic?"

"For example, if you use the second-level Strong Wind Technique to send the explosives to the enemy and ignite them, wouldn't that be equivalent to using a second-level magic to create a fourth-level or even stronger magic power?"

Linde blinked and confirmed that he was not mistaken. The person in front of him was indeed Reina.

How come this kid has become so smart today? He has already started thinking about using gunpowder and magic to make a magical cannon.

Before Linde could speak, Reina continued, "The strong wind technique won't work. We should find a more powerful magic that can be accurately delivered."

Have you already thought of the prototype of the missile?

"No, no, this method is not practical at all. We are using high-level magic to deliver the weapon over long distances. Why not just use high-level magic to attack it directly?"

Lena rejected her own plan again, and then she turned her eyes to the craftsmen around Lind.

"Is it possible to reduce the amount of the so-called gunpowder you made, stuff it into stones, and let these stones explode like magic when thrown out? In this way, the stone fragments can also injure the enemy."

Lind looked at Reina in surprise. Did she think of the fragmentation grenade so quickly? And this time Reina didn't insist on using magic.

At this time, Susan, who had gotten up from the ground in a panic, said, "But Miss, if we reduce the weight, we won't be able to cause effective damage to high-level professionals."

"How many high-level professionals does a noble have?"

Reina looked at her knights. Most of them were third-level professionals, slightly inferior to Linde. However, among their peers, they were already considered geniuses. Coupled with their equipment, they would be the most terrifying killing machines in a melee.

"Susan, the power of the explosion just now has been reduced to one fifth of its original power. Do you think you can withstand it head-on?"

In response to Reina's question, Susan tapped the shield on her wrist and said confidently, "If it's a head-on attack, I'm confident that I can block it five or six times without getting hurt."

Then Reina looked at Lind again.

"So, brother, how much gunpowder can the territory produce in a day? If all the alchemical equipment and workers in the territory are used to produce gunpowder, it should be possible for those ordinary soldiers to use gunpowder continuously, right?"

After that, Reina also gave a detailed explanation of the production of the remaining alchemical materials and gunpowder in the territory.

Susan at the side shut her mouth. What she just said was about using a shield to block the attack head-on. When she thought that even ordinary people could use this kind of weapon, and that there might be several of them, Susan began to sweat coldly.

Yes, high-level professionals are not cabbages. The young lady, a sixth-level professional, is already a rare genius-level player that only appears once in a century.

Linde didn't answer, but circled around Reina, as if he wanted to see if Reina was possessed by something.

"What's wrong, brother? Is there something wrong with what I said?"

Reina drew circles on the ground with her feet unconfidently.

"No, absolutely."

Lind encouraged him, "To be honest, I haven't even thought of many of these ideas yet. You've done a great job. I will consider the plans you mentioned carefully."

The beginning and the end are completely correct. To be honest, the correctness is a bit exaggerated. You know, gunpowder in the original world also went through a long period of research and practice before it really became the dominant force on the battlefield. But Lena concluded and predicted the future of gunpowder just by watching the gunpowder mining once. Lind even felt that Lena was more like a time traveler than himself.

After all, in this world where magic really exists, Lind can't guarantee whether gunpowder can still have the same status as it did on the battlefield in his previous life. But Lena's vision is not only not bound by magic, she even relies on magic to start studying how to use gunpowder.

Reina is not only a genius in engineering, she might also be a natural born general.
