"Your Majesty, the renovation of the castle has proven that this tap water system is effective. Are you going to install this system in already built apartments?"

If he really plans to vigorously promote this tap water system, Gita will have to allocate some manpower from the department and organize them to mass-produce supporting water tanks, water pipes, faucets and other copper products.

"I also hope that the people in my territory can use tap water as soon as possible, but unfortunately, it is not possible yet."

Owen shook his head regretfully, the key problem was Copper.

There are many advantages to using copper to make components such as water pipes and water tanks.

First of all, the material is not easily corroded, can withstand high and low temperatures, will not break or deform easily, and has good stability.

Secondly, copper ions also have the effect of disinfection and sterilization, and will not produce toxic or harmful substances to the water quality.

In addition, there will be no dirt inside the copper pipe, keeping the water clean.

Finally, it is durable and has a long service life, which can last for decades.

The above are all the benefits that Owen learned from Winston, and the shortcomings are caused by the current situation.

"Although Bianzhu Town also produces copper ore, compared with iron ore, the output is still too small."

It is precisely because of this that copper is called a precious metal and is eligible to be minted into currency and circulated in the world, even if it can only be minted into copper coins of the lowest value.

Installing such a running water system in the lord's castle can make the lord look very high-class.

If you want to promote it comprehensively and let the residents use it, the cost will be too expensive.

"Moreover, the copper produced must be used to make more important things - bullets, so we cannot divert too many copper resources to build people's livelihood."

The current situation in Border Guard Town is not stable, and it is necessary to ensure that the People's Army has enough bullets to deal with external threats.

In addition to bullets, copper is also used in other places.

For example, the piston rings that seal the inside of the cylinder of a steam engine and the gaskets outside the cylinder are all made of copper.

"It is mainly these two reasons that restrict the comprehensive construction of the tap water system." Owen said.

"Then the comprehensive installation of the tap water system can only be postponed." Weiru said with regret.

"It turns out that the Marquis has such deep considerations." Gita nodded in understanding, "The problem lies with copper. Iron rusts easily and is not suitable for making water pipes. It would be great if there were chromium ore in the mining area of ​​Bianshu Town.

"

"oh?"

Hearing this, Owen looked at Gita curiously and asked: "Why did you say that?"

"Your Majesty, the book you gave me mentioned an alloy called stainless steel. It is corrosion-resistant, will not rust, and is hard enough. It is very suitable for making water pipes and replacing copper in the tap water system.

Tube."

Gita told the truth: "However, to produce this kind of stainless steel, iron and chromium are essential."

"Well, that's good! Gita, your study progress has accelerated a lot."

Owen praised Gita unstintingly, and he absorbed new knowledge as quickly as himself.

"As you said, stainless steel is indeed an ideal material."

The reason why Gita's learning progress suddenly accelerated is probably because the Ministry of Industry has been relatively well-staffed recently, and he has more time to learn new knowledge.

That's fine, if the actual operations are left to others, Gita can calm down and expand research in other important fields, such as the field of alloys.

"Thank you for the compliment, Lord Marquis." Gita scratched the back of her head in embarrassment.

Mapel glanced at Gita, she also really wanted to get Owen's praise.

"The dwarves are the best at exploring new mineral veins." Owen folded his arms, "Tilion has been back for so long, I don't know if he can invite the lord of Nuva here."

Chromium, mainly found in chromite.

Owen wanted to ask if the dwarves' new underground city was near Nuva. I heard that they would thoroughly survey the mineral veins near the city.

In addition, Irving also wanted to ask them to investigate the Hengwen Mining Area and Tianqiong Mining Area near Bianzhu Town.

There has never been a comprehensive and thorough survey in these two mining areas. God knows if there are still some unknown new mineral veins hidden there.

"Okay!"

Irving said to the people present: "The water system has been tested. Everyone should go back and do their own things. Don't gather here."

Hearing this, everyone nodded and evacuated the room in an orderly manner.

When Owen walked to the door, Angelica, who was leaning against the door, suddenly spoke in admiration: "I didn't expect that the Marquis of Essen was a knowledgeable nobleman who could design such a convenient tap water system."

During the previous test, Angelica remained silent from beginning to end, and Owen thought she was not interested in the tap water system.

It now seems that she was listening carefully to everyone's discussion.

In response, Owen raised the corner of his mouth slightly and asked, "Didn't you hear that I invented many things when I was in the Holy Kingdom of Caleb? For example, paper, cement, muskets, etc."

"Have heard of it."

Angelica responded calmly: "Seeing is better than hearing. In the past few days, seeing you directing everyone to renovate the castle, and finally successfully sending water in, really opened my eyes."

"Then I guarantee that you will see more eye-opening things in Border Guard Town in the future."

Owen showed a confident smile and walked past Angelica.

Watching Owen's retreating back, Angelica thought to herself: The church was interested in this man's ability to make humans and demihumans live in harmony, but it ignored his more powerful aspects.

Marquis Eisen, the knowledge he possesses may be enough to subvert the world.

"No wonder Freya also asked me to pay more attention to Marquis Essen. This man is indeed extraordinary." Angelica murmured in a low voice.

Then, she got up and caught up with Owen.

The mission assigned to Border Guard Town was to protect Owen, and Angelica did not forget it.

It was temporarily impossible to lay all the tap water pipelines in Bianzhu Town. Irving specifically asked Winster and quickly found a replacement plan.

The next day, Owen summoned Gita and Vilu again to inspect and confirm that there were several wells that had been drilled in Bianzhu Town.

Within a few days, a new gadget appeared next to all the wells - a hand-operated water pump.

After the construction was completed, Owen gathered the residents around the well and demonstrated it to them in person.

Just pour some water into the hole and keep pressing the lever to create a pressure difference, and the well water will be pumped up quickly.

When they saw the water pouring out of the pipe, people couldn't help but exclaimed and said it was magical.

After that, Owen selected a few civilians to come over and use it himself. Every time the water came out, the people around him would make a cry.

It can be seen that they are all very interested in this water pump.

Although it is not as convenient as the tap water system, it is much better than before. As long as you keep pressing it, water will be drawn up continuously. You no longer have to go to the well to draw water from the bucket.
Chapter completed!
