After dinner, the students had free time.

Some people will study in the dormitory or library, some will go to the training ground to hone their martial arts and cast spells, and some people will indulge in their own desires and squander their youth.

Charles sat at his desk in his dormitory, sketching a decanter on paper.

In the slime gum that Langsha studied, the easiest way Charles could come up with to remove physical impurities was to use a centrifuge.

It's just that slime glue is only used in this method when it is liquid at high temperatures, so it is quite troublesome to make the corresponding machine.

It's not theoretically difficult to make a small centrifuge for use in the laboratory, but if it is to be industrialized and mass-produced, Charles thinks that the decanter centrifuge used to treat sludge that he has seen in his previous life in a sewage treatment plant can give it a try.

The principle of a decanter centrifuge is simply that a cylinder with a conical front end is reduced to rotate at high speed, and material is continuously added from the middle tube. The heavier solids in the material are thrown onto the inner wall of the cylinder under the action of centrifugal force and aggregated, and then carried away by the spiral blades in the cylinder that have a difference in speed with the rotation speed of the cylinder, and are discharged from the front end to the outside of the cylinder. The lighter slime glue forms an inner ring in the rotating cylinder, which is discharged through an opening at the bottom of the rear end of the cylinder.

Don't look at its simple principle, it also needs to invest a lot of manpower and material resources in research, such as ensuring the temperature of slime glue in a liquid state, the viscosity of slime glue, the parameters of spiral blades, the differential between cylinder and spiral blades, etc., there are still many problems to be solved.

Charles will draw a schematic diagram for later use, and find someone to study and produce when needed.

After that, it is necessary to produce qualified slimes, to bring [REDACTED] countless beautiful legs to this world in red, blue and white snakeskin bags in slime socks, and to solve the problems of spinnerets, looms, and so on.

Alvin arrived a little later than Charles had expected, and Enrico came with him.

As soon as Enrico entered, he locked the door of the dormitory, pulled a chair and sat behind Charles, and then said to Charles solemnly: "You're in trouble." ”

Charles put the paper back in the drawer, turned and sat down, and glanced at Enrico to see that he was serious, and he was still smiling.

So he asked, "What misfortune has found me?"

Enrico said solemnly: "The cake you gave Miss Diana last night was known to her pursuer, and the person said that he would teach you a lesson. ”

Charles rolled his eyes at him, and then said, "Didn't that boy from Conradin not get to school, and his doglegs started to come out and bite?"

As he spoke, he took out two bottles of wine, snacks and a low table from the storage ring, and beckoned Enrico and Alvin to eat and chat.

Enrico poured himself a glass of wine, and then said, "It's Christian from Class 7, and he said he had met Miss Diana or something before. ”

Charles let out an "oh" and said, "I know this, I was there." ”

"Ignore him, he's fighting with his little aunt Margaret for the succession to the throne, and it stands to reason that I am in the same league as Aunt Margaret. ”

"Don't talk about it. ”

He then took out a pair of boots, a necklace, and a belt from the storage ring and handed them to Alvin.

Alvin curiously fiddled with the three antiques that Charles had just bought from the Elf's workshop last year, and asked, "These are all good things, you want me to buy them for you?"

Charles shook his head and said, "The merchants on the island will hold an auction on the next day off, and I'm going to sell these several." ”

"You help me make up a story for them, it's very sensational, it's the kind that arouses people's desire to buy, and when the time comes, I'll give you at least three points of rebate. ”

Alvin looked at Charles with a look of horror in his eyes, and he said, "I've seen a pit man, but I've never seen a pit like you." ”

Charles drank wine and said with a smile: "The auction is a place for slaughtering local tyrants, and those who will buy things there are rich people, and there is no psychological pressure to pit their money." ”

"I've taken it!" Alvin said excitedly, "The most touching thing is nothing more than stories of love and war, just make up a new one with similar routines." ”

After he finished speaking, he returned the three things to Charles, and it was enough to know what they looked like and what they did.

When it was over, the three of them began to drink and talk about the interesting things that happened in the academy.

The brothers and sisters in the academy are also quite capable of making trouble, in recent days, there have been several fights and duels for the right of spouses, and the two student groups that have been opposed since the freshman era staged a good show of "the undercover agent I sent to the opposite side is actually the undercover agent sent from the opposite side", and there are people who owe money and are not repaid by the creditors who are tied up and hung on a tree.

Charles and Christian's upcoming school youth drama is just a drop in the ocean of campus life on the entire island, and it is inconspicuous.

For Charles, the soldiers will block the water and cover the earth, and if the other party comes to find trouble, it will be like those people in the second shift a while ago when they were looking for trouble.

When the three of them were slightly drunk, there was a knock on the door of Charles's dormitory.

Charles was surprised by the people who came.

Hayden didn't expect Enrico and Alvin to be here too, and they seemed to have drunk quite a bit.

He said to Charles anxiously, "Someone will be making trouble for you lately." ”

Charles said indifferently, "You're talking about Christian." ”

"So you know, too. Hayden breathed a sigh of relief, if only Charles had prepared in advance.

Charles continued: "You help me get out of the way, and say that I am in league with Count Margaret of their Kalmar Alliance. ”

Hayden frowned and asked, "Is the relationship between the two of them good?"

Charles smiled "hehe" and said, "On the contrary, they are about to fight." ”

"The king of the Kalmar Union has always been in poor health, and it is the root cause of his illness when he was beaten and seriously injured when he hooked up with his wife in a private interview with his young man. ”

"Twenty years ago, the king wanted to marry his sister Margaret to a bad old man, but Margaret ran away and joined the caravan of the elven princess Elizabeth on the way. ”

A few years later, Margaret received the support of the elves and returned to China strongly, and no one dared to mess with her anymore. ”

"The king is dying all these years, and the jury is still out on whether the throne will be inherited by his sister or his son. ”

Hayden pondered after listening to Charles's explanation, his home was in the west, and he didn't know much about things in the east.

He thought for a moment, and then asked Charles, "Are you close enough to Earl Margaret, will she stand up for you?"

Charles nodded and said, "When she was in the caravan of the elf princess, she passed by my house several times, and my grandfather and parents received her very warmly, and we had a good relationship. ”

These things were only told to Charles a while ago when Margaret came to the South Sea Farm for a meeting, and not long after Charles was born, she went to Charles's house with the caravan.

When Charles was first held by Elizabeth, he was so frightened that he urinated on the elf princess, and then after being washed by Elizabeth in water like a winter melon, it was Margaret who handed the towel on the side.

It's just that Charles's attention was not focused on the surroundings at that time, and he only felt that there was a crowd of onlookers next to him, but he didn't expect that one of the onlookers was Margaret.

Of course, this matter can't be said, but it's enough for Hayden to feel a little more at ease.

Political creatures will not act rashly when dealing with those on the side of their political opponents unless they have absolute certainty or a good interest.

It's just that Hayden still has a concern, he said: "Recently, it has been rumored that Christian recently obtained the sword of the Demon Empress Catherine, and that sword was the weapon used by Catherine to defeat Her Excellency Pendragon, which has been confirmed by Her Excellency Pendragon not long ago. ”

"I'm afraid he'll find an excuse to duel you. ”

Charles was stunned, the sword he had sealed with reinforced concrete had finally been made by Christian.

However, he was not worried, the final winner of the Empress's ancestor to defeat Artoria back then was the ancestor's stuffy stick, and even Artoria's soul was injured by that stick.

He told Hayden: "Don't worry, the most important factor in determining the outcome of a battle is people, and the same weapon plays a different role in different hands." ”

Seeing Charles so calm, Hayden could only sigh and say, "Be careful yourself." ”

After he finished speaking, he was dragged by Charles to stay and drink.
