Charles stayed in the castle for three days.

Not to mention that the castle feels very classy, the living environment of the castle built for war is not pleasant.

Charles sat on a bed about the size of his student dormitory, reading a book, in a room less than ten square meters, and if it weren't for the decoration—that is, a few tapestries hanging on the wall—he would have thought he was in a prison cell.

The only large room in the castle was occupied by Antoine II, and Charles and his wife could only live in such rooms.

However, they were not restricted in their freedom, and it wasn't long before Genaro came to visit.

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

When Genaro came in, he looked at Charles's bedside lamp with interest for a while, pulled a chair and sat aside, and then said to Charles, "Louie is gone." ”

Charles, who was reading a book, let out an "oh" and continued to read a book in his hand that recorded earth-based magic.

The book was borrowed from the castle's library, and the earth and its advanced stone magic were mostly used for defense and field control, and it was also good for offense.

Louis is forced to flee from the castle to the surprise of Charles and Genaro, and is "protected" by the murderous Praetorian Guards throughout the day, even when he goes to the toilet, and the ghost knows whether he will be killed or fucked next.

The next thing Charles can guess without thinking about it, and Louie's "absconding in fear of crime" is a sure thing.

I'm afraid that Louis's political wisdom is not half that of Genaro, and if he judges Antoine II's thoughts, he will stay to make things clear, rather than give people a chance to cut the blame.

It's not about IQ, it's about the content of the education he received, and apparently Louie didn't go to make-up classes during the time he regained his IQ.

Gnaro continued: "I have inquired in the past two days, and Grandpa Beretta's butler and Grandpa Beretta have a conflict in secret. ”

Charles turned a page of the book and said, "This doesn't matter, now that Duke Beretta's body and life have been ruined, it's useless to say anything." ”

"Now everyone's main concern is the person who can drive the monster. ”

Genaro nodded, and the day after the battle, Charles had a rehearsal with him, if these monsters scattered around the city and attacked the village, and did not fight with the raiding party, most of the cities in this world would be trapped and killed without foreign help.

The emergence of cities relied on the surrounding farms to provide food, as well as convenient transportation to transport food to the city.

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

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

There are more mountains and monsters in the kingdom of Schberg, 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 in foreign wars in the future.

Charles continued: "You have to learn a lesson from what happened to Duke Beretta, beauty can also kill. ”

Genaro's face flushed.

Charles continued: "I'm not qualified to say anything about you, you know some truths, you can control yourself." ”

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

If Antoine II had arrived the next morning, the Duke of Beretta would already be a corpse.

At this time, Genaro said embarrassedly: "Charles, how about one more person in our team?"

Charles put down the book and looked at Genaro, scratching the back of his head a little embarrassed.

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

"No, no!" Gnaro waved his hand hurriedly, "it's Sister Rucia that day, she's traveling around right 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!" Gnaro waved his hand again, "I'm just ......"

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

"When His Majesty has left us will also depart, and then I will sail all the way west to Trapani, where I will sail south. ”

"My advice is that you stay in Trapani for the winter, where the adventurers make their living in the woods, depending on how much you can learn from them. ”

Genaro thought for a moment and nodded.

Charles quipped, "Can you help Deborah?"

Gennaro smirked and fooled over.

After driving Genaro back to rest, Charles lay on the bed for a while, feeling that the place was a little 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 himself up before going to sleep.

Thanks to Antoine II, the bathrooms are now stocked with hot water all day.

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

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

It's just that he looked at Xiao Ru's eyes coldly, and it is estimated that if it weren't for the magic that could restore people's missing limbs, Xiao Ru would have run away from home.

Charles sat down on the edge of the bath, which was four or five meters in diameter, and then asked, "Your Majesty hasn't rested yet?"

Antoine II sighed and said: "I am old, I was injured too much when I was young, and now my whole body aches when the weather is cold. ”

Charles smiled after hearing this, and said, "I have a secret recipe from the elf clan to treat the dark wounds of the body, I don't know if you dare to use it." ”

Antoine II sneered and said, "It can't be some way to overdraw your body, right?"

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

Speaking of the elven doctor, Antoine II's expression suddenly became solemn, and he asked Charles, "Do you remember what happened to us being poisoned?"

"Yes. Charles nodded.

Antoine II said: "It is not only our family that has been poisoned, but the entire people of Seven Hills City have been poisoned. ”

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

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

Antoine II asked, "Have you ever heard of a method of poisoning, which is to infiltrate a stone into which the poison slowly dissolves into the water?"

Charles thought for a moment and said, "This method...... I don't think I've heard of it. ”

"I'll write to help you ask Aunt Victoria and Aunt Lef, they are so well-informed that they might know. ”

"Don't you know that either?" said Antoine II.

As the king, the people in the entire royal capital have been poisoned by the evil ** of chronic poison, and the pressure is naturally huge.

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

"Now we can only make the antidote cheap and delicious, and make it a popular drink to promote in the city. ”

Charles looked at Antoine II in a little surprise, this is a good method.

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

Antoine II glanced at Charles, the question was not a secret, it was easy to estimate, and replied: "About two hundred thousand." ”

Charles nodded, and then made a silent calculation.

According to this number, 220,000 people are rounded up, and then calculated according to the current water consumption of 50kg per person per day, then the entire city consumes 11,000 tons of water per day. If you add 5% of the public water and 15% of the pipeline leakage, then if you want to build a water plant in Qiqiu City, the scale of this water plant will reach 13,282.5 tons per day, which is calculated according to the scale of 20,000 tons/day.

After finishing the calculation, he pouted, the difficulty of this water plant is there, but it is not an insurmountable difficulty.

Compared with the construction of flocculation tanks, clean water tanks, filtration tanks and pumps, etc., the design and pipeline construction of various facilities and water supply networks are the troublesome places.

Fortunately, there are relevant books in the golden thigh sent by Mrs. Zhang, and the design manual is on the line, and someone has designed the process of a waterworks when he was doing course design in college in his last life, and his graduation project is to design the pipe network of an urban area.

The magically powered water pump was no longer a problem, Charles's hair dryer was changed to a water pump.

Flocculants are not a big problem either, pyrite and bauxite are already available, as are chlorine for disinfection, and the rest is the rest

3FeS?2+11O?→Fe? O?+6SO?

SO?+H? O→H? SO?

Al ? O?+3H? SO?→Al? (SO?)? +3H? O

and

2NaCl+2H? O→aOH

It's a thing.

There are also ways to disinfect with other methods, whether it is the production of ozone with corona or the ultraviolet disinfection lamp converted from a magic lamp, which has been patented by Diana.

The filter tank is easier to do, and the filter material can be made of sand.

Although water plants cannot solve the toxins in the water, it is far more convenient to protect the water source than scattered wells and rivers, and it can also reduce the occurrence of other infectious diseases.

However, Charles didn't plan to touch the business of the waterworks, it involved too much, presumably Antoine II didn't dare to put the lifeblood of a city in Charles's hands, and when the time came, he would let the Jiuyang Chamber of Commerce sell faucets.

"What are your plans?" asked Antoine II, a faint hint of anticipation in his mind.

In Antoine II's expectant eyes, Charles finally shook his head, and he decided to throw this matter to the Dagger and them to do, and everyone was relieved that the dwarves would do such a project.

Charles found that the soul of his infrastructure had begun to awaken recently, and with the development of the industrial level of the Rurik Kingdom and the Elven Court, many things that could only be thought about before were no longer flowers in the mirror and moons in the water.
