Charles lived in the castle for three days.

Not to mention the castle looks very high-end, the castle living environment built for the war is not flattering.

Charles was sitting on a bed about the size of the student dormitory and reading a book. The room he was in was less than ten square meters. If it weren't for the decorations—that is, a few tapestries hanging on the wall—it was not bad, he thought himself in the cell.

The only large room in the castle was occupied by Antoine II, and Charles and the others could only live in such a room.

However, they were not restricted from freedom, and it didn't take long for Gennaro to come to visit.

It was already night, and the bright moon hung high outside the narrow window.

After Gennaro came in, he looked at Charles' bedside lamp with interest for a while, pulled up a chair and sat beside him, and then said to Charles, "Louis ran away."

Charles, who was reading a book, let out an "oh", and then continued to pick up a book in his hand that recorded earth magic.

This book was borrowed from the castle's library. Earth-based magic and its advanced stone-based magic are mostly used for defense and field control, and they are also good for offense.

Louis was forced to escape from the castle, but Charles and Gennaro didn't expect it. He was "protected" by the fierce and murderous Praetorian guards all day long, and even going to the toilet was no exception. The ghost knew that he was going to be killed next. Still being done.

The next thing Charles and the others can guess without thinking. It is a sure thing for Louis to "run away in fear of crime".

I'm afraid Louis's political intelligence is not as good as half of Gennaro's. If he judges Antoine II's thoughts, he will stay and make things clear, instead of giving people a chance to take the blame.

This has nothing to do with IQ, but with the content of education received. Obviously, Louis did not go to make-up classes during the period of recovery of IQ.

Gennaro continued: "I have inquired about it in the past two days. Grandpa Beretta's housekeeper and Grandpa Beretta have a secret conflict."

Charles turned a page of the book and said, "This is not important. Now that Duke Beretta's body and life are ruined, it is useless to say anything."

"Now everyone is most concerned about the person who can drive the beast."

Gennaro nodded. Charles had a game with him the day after the war. If these monsters scattered around the city and attacked the village, they would not fight to the death with the crusade. Without foreign aid, most cities in the world would will be trapped.

The emergence of the city relies on the provision of food from the surrounding farms and the convenient transportation of food to the city.

If these two points are destroyed, the city can only eat the stored food, and everyone will starve to death after eating the stored food.

Charles can be sure that Antoine II's real idea at this time is to secretly find this person, and then take it under his command. A baron or even a viscount can be used as a bargaining chip.

There are many more monsters in the mountains than the Schberg Kingdom, and the same is true on the border. If this person can be used by Antoine II, then the army of monsters can be used as the first wave of cannon fodder to open up the situation in the future.

Charles continued: "You have to learn from what happened to Duke Beretta. Beauty can kill people."

Gennaro's face suddenly turned red.

Charles continued: "I'm not qualified to say anything to you. You know there are reasons. You can control yourself."

Duke Beretta's strength is not weak, but he doesn't know what kind of magic he has or what medicine he has taken. The piston movement for many days can actually produce the effect of burning the soul.

Had Antoine II arrived the next morning, the Duke of Beretta would have been a corpse.

At this time, Gennaro said embarrassedly: "Charles, how about adding another person to our team?"

Charles put down the book and looked at Gennaro like that, scratching the back of his head a little embarrassedly.

"Which girl did you kidnap again?" Charles asked.

"No, no!" Gennaro waved his hand quickly, "It's Sister Lucia from that day. She is traveling around now, so we can just be with her when we leave."

Charles touched his chin and asked, "Do you like her big sister type?"

"No no!" Gennaro waved his hand again, "I just..."

Charles didn't listen to him, interrupted him and said, "You can settle the relationship within your squad."

"When His Majesty has left, we will also leave, and then I will go all the way west to Trapani, where I will take the boat south."

"My suggestion is that you stay in Trapani for the winter. The adventurers there make a living in the woods, and see how much you can learn from them."

Gennaro thought for a while and nodded.

Charles quipped: "Can you help Deborah decide?"

Gennaro fooled the past with a smirk.

After driving Gennaro back to rest, Charles lay on the bed for a while, feeling that the place was really cold.

So he left the room and went to the bathroom at the back of the castle, intending to take a hot bath to warm up before going to sleep.

To Antoine II's blessing, there is now hot water in the bathrooms throughout the day.

It's just that Charles didn't expect someone in the bath. He was about to leave, but was caught.

"Oh, the cost is not small." Antoine II teased Charles.

It's just that he looked at Xiao Xi with cold eyes. It is estimated that if it wasn't for the magic that could restore a person's damaged limbs, Xiao Xi would have left home.

Charles sat down by the four- or five-meter-diameter bath, and then asked, "Has your majesty rested yet?"

Antoine II sighed and said, "I'm old, I suffered too many injuries when I was young, and now the weather is cold and my whole body is sore."

After listening to Charles, he smiled and said, "I have a secret recipe from the elves for the treatment of body injuries. I don't know if you dare to use it."

Antoine II sneered and said, "Could it be some way to overdraw the body?"

Charles said indifferently: "Don't you hire an elf doctor, let them see if there is any danger."

Speaking of the elf doctor, Antoine II's expression suddenly became solemn, and he asked Charles: "Do you remember our poisoning?"

"Remember." Charles nodded.

Antoine II said: "It's not just our family that was poisoned, the entire Qiqiu City was poisoned."

Charles looked at Antoine II opposite the bath in surprise, and then asked, "Someone poisoned the water source?"

The most effective way to poison people in a city is to poison the water source.

Antoine II asked: "Have you ever heard of a method of poisoning, that is, the poison is infiltrated into the stone, and when the stone is thrown into the water, the poison will slowly dissolve into the water? "

Charles thought for a moment and said, "This method... I don't seem to have heard of it."

"I'll write to you and ask Aunt Victoria and Aunt Leif, who are well-informed and may know."

"Don't you know?" Antoine II was a little frustrated.

As a king, people in the entire capital have suffered from chronic and poisonous incidents, and the pressure is naturally enormous.

He continued: "Actually, thanks to you, it was the people you found in the cave who were poisoned."

"Now all we can do is make the antidote cheap and tasty and make it a popular drink in town."

Charles looked at Antoine II with a little surprise, this method is not bad.

He thought for a while and asked, "How many people live in Qiqiu City?"

Antoine II glanced at Charles, this question is not a secret, it is easy to estimate, so he replied: "About 200,000 people."

Charles nodded, then counted in his heart.

According to this number plus 10% and rounding up to 220,000 people, and then calculating the current consumption of 50kg of water per person per day, the entire city consumes 11,000 tons of water per day. If you add 5% of public water and 15% of pipeline leakage, then if you want to build a water plant in Qiqiucheng, the scale of this water plant will reach 13,282.5 tons of water per day, then the scale of 20,000 tons per day Come to count.

After the calculation, he curled his lips. The difficulty of this water plant is there, but it is not an insurmountable difficulty.

Compared with the construction of flocculation tanks, clear water tanks, filter tanks and pumps, etc., the design and pipeline construction of various facilities and water supply pipelines are the troublesome places.

Fortunately, there are related books in the golden thigh sent by Mrs. Zhang. It is enough to design it according to the design manual. When a certain person was doing course design in college in his previous life, he designed the process of a waterworks, and his graduation project was about the management of an urban area. web design.

The magic-powered water pump is no longer a problem, and Charles's hair dryer has been changed to a water pump.

The flocculant is not a big problem. Pyrite and bauxite are already available, and so is the chlorine gas for disinfection, and the rest is

3FeS?2+11O?→Fe?O?+6SO?

SO?+H?O→H?SO?

Al?O?+3H?SO?→Al?(SO?)?+3H?O

and

2NaCl+2H?O→Cl?+H?+2NaOH

The thing is ~lightnovelpub.net~ There are also ways to disinfect by other methods, whether it is to use corona to produce ozone or to use the magic lamp of lighting to change the ultraviolet disinfection lamp, all of which have been registered and patented by Diana.

The filter tank is better, and the filter material is sand.

Although water plants cannot solve toxins in water, the protection of water sources is much more convenient than scattered wells and rivers, and it can also reduce the occurrence of other infectious diseases.

However, Charles does not intend to touch the business of the waterworks, because it is too involved. Presumably Antoine II would not dare to put the lifeblood of a city in Charles' hands. At that time, he will let the Jiuyang Chamber of Commerce sell the faucets.

"What are your plans?" asked Antoine II, a faint expectation in his heart.

Under the expectant eyes of Antoine II, Charles finally shook his head. He decided to leave this matter to He Dou Dagger and the others to do it. The dwarves can rest assured when they do such a project.

Charles found that his soul of infrastructure has begun to awaken recently. With the development of the industrial level of the Rurik Kingdom and the Elf Royal Court, many things that could only be thought of before are no longer the flowers in the mirror and the moon in the water.
