Before Jack and Daisy go out, they find a college professor and spend a lot of money to bring him to their home and ask him to take a break from Christmas to teach Seamus.

Although Seamus had been reviewing the math he had learned before, he had returned it to his teacher as early as after graduating from high school. His current level of mathematics may not be as good as when he was in the third year of high school in his previous life.

The professor, though agreeing to put aside the Christmas holidays, was skeptical about teaching an eleven-year-old child, and he did not think that a child could learn such profound knowledge.

Seamus also didn't intend to learn much during the Christmas holidays, as it was clearly not something that could be successful in a short period of time, and it was not yet aided by the ability panel. The main purpose of this time is to learn how to apply it simply, because there is only one last level left in the magic array tutorial book, which is to independently design a complex mobile magic array.

The magic array used on the Vulcan cannon was only drawn by Seamus according to the information on the cat, so the bomb could only be fired in a straight line. It looks like enough on the Vulcan cannon, but it can only walk in a straight line, which will undoubtedly cause a lot of trouble.

In order to ensure the progress of this study, Seamus also prepared a lot of intelligence enhancers in advance, this is not a troublesome potion, there is a recipe in the fourth-grade potions textbook, and he can now make a wisdom enhancer, but there is no way to ensure the success rate, and the effect of the intelligence enhancer made by a clever potion master will be better.

It's a pity that Slughorn doesn't lack money for this, he has always only sold high-grade potions, otherwise he could have bought some.

The Wisdom Enhancer is only a short-lived potion that will make your mind clearer for a period of time, your brain will be more active, and it will even have a certain effect on resisting the Confusion Charm. But it doesn't really increase a person's intelligence, it only increases the speed of your brain for a short period of time.

It's not uncommon for potions to really increase intelligence, but their recipes have long since been lost in the wheel of history, and no one can refine them anymore.

Currently, only alchemical items that increase intelligence exist, such as Nicol Lemay, who made a head ring that has the same effect as a stellar but can last for a long time.

Legend has it that the elves who once existed also had similar items, and their sacred place had a tree of life, which was their sacred tree. The Tree of Life condenses the water of life, which drip down the roots of the tree and fall to the ground, allowing anyone to drink the water of life and gain a chance to increase their wisdom.

Unfortunately, the elves have long since disappeared from the war with the wizards, and the tree of life has since withered, and there is no more water of life. Naturally, Seamus couldn't get it, and as for the headbands made by Nicol Lemay, in his more than 600 years of life, he only made three.

It must have cost a lot of money to make it successful, and Seamus no longer had the luxury of expecting it, and the last one is the well-known Ravenclaw tiara. It was crafted into a Horcrux by Voldemort and stored in the Room of Requirement, where legend has it that wearing a crown can lead to infinite wisdom.

Seamus had already searched for it, and on top of a cabinet, above the head of a statue, lay the Ravenclaw crown, rusty, dusty, and cobwebs.

Even so, Seamus didn't have the idea of getting it, and even Professor Dumbledore would be tempted by the magic on the resurrection stone, let alone him. Although it was made when Voldemort was in school, the dark magic on it should not be underestimated, and Seamus would never take the crown without absolute certainty.

So after finding the crown again, Seamus only glanced at it twice and left, and now the intelligence enhancer is his best choice.

"Knock knock", there was a knock on the door, Seamus hurriedly went to open the door, now he can't use magic at home, because Daisy may have arrived in Switzerland now, if he uses magic again, within a few moments, the owl of the Ministry of Magic will send a letter of dismissal.

Although he had known this was the case, Seamus had Daisy and Jack go to Switzerland, after all, the two of them might have had less time off than he had for more than a year.

Opening the door, there was not the white-haired and bald old man he imagined, but a middle-aged man, but his hairline made Seamus not doubt his math skills at all.

"Please come in, is it Professor Charles Carter?" Seamus stepped out of the way, smiled and brought the middle-aged man into the house, and poured a cup of black tea on the coffee table.

"Is it me, you're going to come to me to study math?" Professor Charles sat down and took a sip of black tea, "It tastes good." ”

Seamus looked at the man in front of him, the top of his head was a little reflective, he didn't wear glasses, he was wearing a trench coat casually, his hair was messy, and his beard was very casually shaved, "Yes, I want to be able to learn the math of space." ”

Charles scratched his head and asked, "Are you sure you want to learn these things?" Although I am very impressed by your attitude that you want to learn mathematics, I always feel that it is still too early and you should learn simpler things at your current age. ”

Seamus had expected it this time, after all, not everyone can cross it, and at this age to study advanced mathematics, although such people are not nothing, they are also extremely rare. He took out what he had prepared, a workbook for advanced mathematics, and pushed it in front of Professor Charles, "This is my current level, in fact, I don't expect to learn it in a short time, what I urgently need most is someone to lead me through the door." ”

Professor Charles picked up the workbook and looked at it, this is the result of Seamus these days, and it is really a very difficult task to teach advanced mathematics on his own. He only hoped that he would be able to make his math level reach the level of being able to design a mobile magic array these days, and he didn't need to be able to use it flexibly.

"It's unbelievable. Professor Charles put down the workbook, his face full of surprise, "If this is really your level, then you don't need to go to secondary school at all, there are many college students who are not as good as you." ”

"It's over. Seamus achieved his goal and gained the professor's trust, stood up, and pointed to the classroom that had already been set up, "Then let's start now." ”

"You're in a hurry. Professor Charles also stood up, "That's right, if it weren't for such a high level of action, then no matter how talented a person is, it is impossible to reach such a level at the age of 11." ”

......

Time flies, the time has reached 6 o'clock in the evening, and today's teaching is over, the learning process is not so good, and Seamus also understands why Professor Charles has a reflection on his head.

The process of learning mathematics is much more abstract than learning magic, but with the help of intelligence enhancers, Seamus can barely keep up. During the learning process, Seamus took a sip of the enhancer from time to time to maintain his active thinking.

The enhancer had long been put in a thermos cup by Seamus, and it would not be noticed by Professor Charles, at most he was just wondering why he was drinking such a bad thing?

The taste of the enhancer is extremely strange, although it looks transparent, it tastes extremely bitter when drunk in the mouth, and it also has a strong fishy smell. This is the taste of armadillo bile inside, which is the main ingredient of intelligence enhancers, and the effect is fantastic.

The comparison before and after drinking the enhancer is like the grogginess of not sleeping for thirty hours and the energy after a good rest, although it does not have the magical effect that Seamus imagined, which can achieve the effect of changing thinking, but whether it is in memory or calculation ability, it is not the same.

Brain boosters do not have huge defects like brain awakenings, which are made from fox feces and will become fools if taken for a long time. But the enhancer does not have such a flaw, and the effect is not so powerful, but it only makes the body a little weak, which is caused by the brain thinking too quickly.

So Seamus has also prepared a variety of nutritional elixirs in case of emergency, although there are no side effects, but taking intelligence boosters for a long time will make you rely on this feeling, and the feeling of always having a clear mind is fascinating.

"You were amazing today, I'll be back tomorrow. Professor Charles said goodbye to him at the door.

Seamus didn't stay at his original home today, they bought a new house as a place for him to study these days, and they prepared all kinds of things they needed, and hired a Chinese cook, which is why Professor Charles didn't stay here to eat, this is a person from Sichuan.

"Uncle Zhang, is dinner ready?" asked Ximo in Chinese, and the dishes at noon today were boiled fish fillets, Mao Xuewang and Jiangyou fat intestines. Of course, Seamus is very happy to eat, this is the authentic taste of his hometown, Professor Charles really can't bear it, although Professor Charles can eat spicy, but after chewing a green peppercorn, he was completely defeated.

"Your Chinese is really good, and you have the accent of Xiangxi. Zhang Bo couldn't help but admire, and while serving the dishes to the table, he cleaned up the kitchen, "Wait for two minutes, and there will be a bowl of soup at the end." ”

No matter what Uncle Zhang thinks, it is impossible to know that I spoke Chinese in my last life.

"Alright, don't clean up, let's talk about it after eating. Seeing that Uncle Zhang was about to clean up the kitchen just after cooking, Seamus hurriedly asked him to eat first.

The two of them sat at the table like this, eating and chatting at the same time, "Your craft is really good, this rabbit is fried, hey." ”

"That's it, I rely on this craft to eat. Uncle Zhang looked proud, took a sip of wine, and was indescribably comfortable.

"Pour me a glass too. Seamus handed the cup over and yelled for one.

After eating and drinking, Uncle Zhang put away the dishes and chopsticks, and the two nestled on the sofa together to watch TV.

"Uncle Zhang, you teach me how to cook. ”
