After Rolf's detailed explanation, Field finally knew what his new invention, the 'Magic Activation Solvent', was. Pen, fun, and www.biquge.info

The 'Mana Activation Solvent' is not a simple potion, it is the product of the combination of alchemy and potions, and the 'No. 3 Mercury Gold Solution' is an alchemical by-product of Field's failed experiment to create an 'artificial sun'.

Mercury gold is the most precious alchemy material in the wizarding world (not the kind of chemical product), it contains rich magical power, and its nature is lively, it cannot be collected in nature, it requires advanced alchemy to convert, and it is an important raw material for many precious magic props (such as time turners), but this kind of ' No. 3 mercury gold solution is different from ordinary mercury gold, it also contains a lot of magic, but the properties are very stable, after Field accidentally made it, he didn't think of how to use it, but it was successfully experimented with by Rolf.

Rolf added the juice of the dragon's head fruit and other materials to the No. 3 mercury gold solution to activate it, thus inventing the 'magic activation solvent', a material that is more stable than mercury gold, but contains a lot of magic power. Field looked at the golden-red viscous liquid in Pingzhong, and immediately thought of a use. "Rolf, this would be the best material for drawing magic circles. ”

"Not only that, but there is also the magical mechanical prosthetic you invented earlier, if you add 'magic activation solvent' to the magic prosthetic, then you can use it even without using magic power. Rolf said as he walked over to his desk and picked up a drawing to show Field, "If you use this seal, you can make it into a 'magic reactor' that will power a lot of things, so that the missing power part of the 'magic robot' drawing you showed me earlier will have it." ”

Field looked at the drawing in his hand, on which a spherical object was drawn, which was Rolf's vision for the application of the 'Magic Activation Solvent', and made it into something similar to a 'nuclear fusion reactor' to provide the power needed for the magical robot designed by Fields and Nick Lemay.

"Thank you, Rolf. Field was impressed, and Rolf always remembered the problems he left behind during his experiments. Last year, when they were making a magical mechanical prosthetic for Professor Kettleburn, Field took out the drawings of the magic robot for reference, and Rolf and Field, who were still interested in the production of magic props, discussed for a long time about the difficulties of making robots, which in addition to intelligence, was the problem of energy supply, (Master Nick Lemay originally envisioned using the Philosopher's Stone for energy, but this was too uneconomical.) ）

"Thank you, if you and your teacher succeed, just give me a robot. With that, Rolf went back to his bedside and went on to eat his supper.

"Definitely. Field said earnestly.

With new things to study, Field's alchemy experiment journey has started again, Rolf's design of the 'magic reactor' has many shortcomings, he needs to revise the design well, and then make a small test first, so that he can take it back to Master Nick Lemay during the summer vacation, so that Field's time suddenly became tight again, fortunately, Hogwarts after solving the secret room time and sending away the magic TV station was very calm, and Field had a lot of time to devote to research.

According to Hermione, Field, who was obsessed with research, became a complete otaku, and in addition to the necessary classes, meals and sleeps, he spent all his time in small clubs doing experiments. Until the final exams come.

"With so much going on this year, is the school still in the mood to organize exams? What about the students in the school clinic. "Field was sitting in the library, trying to make up for Hermione's astronomical notes, and of course, Harry and Ron were the same.

"I would also like to cancel the exam, but it is not possible. Listening to Percy, the students who were attacked will be counted as passing. Ron held his lips and said,

Field reluctantly continued his cramming business.

I have to say that Field's rote memorization is still good, and Field passed the exam a week later, and of course the results cannot be excellent.

"Field, if you had spent the whole year studying like you did last week, you wouldn't be where you are now. Hermione said angrily, pointing to Field's name on the results announcement.

"Oh, Hermione, at least my grades aren't bad, you should care more about Harry and Ron's grades. Field immediately began to distract Hermione.

"Well, Hermione, I think I'm pretty good, I'm a big improvement from last year. That Hermione, I'm going to check my broom, I think there's something wrong with it. Harry ran away in a fit of rage. Indeed, Harry's grades had improved significantly, thanks to the gem ring he had obtained in the Slytherin Vault, which allowed Harry to calm down and study very quickly. (Of course, Field had always thought that Harry had wasted the effect of the ring, and that he had very little time to study.) ）

"Harry, I'm going to help you, knowing I'm an expert at this. Field hurried to catch up with Harry.

Ron froze for a moment before he thought of catching up, but by this time Field and Harry were already far away. He looked at Rolf and Ginny, who were gloating around him. Looking at Hermione's unsightly face again, she could only sigh silently, "It's really careless to make friends." ”

On the Quidditch pitch, Harry caught the Golden Snitch steadily, the Gryffindor players cheered and gathered around, and the Gryffindor lion cubs in the stands cheered. Of course, Slytherin's face as an opponent is not so good-looking. Field even saw Malfoy smashing a wall with his broomstick.

"Congratulations, Seid. Field applauded Gryffindor and said to Cedric beside him.

"This year it's just luck, it's not a good strength. I should thank Gryffindor for winning the Quidditch Cup. Cedric was also clapping.

Although Gryffindor won the last Quidditch match, it was Hufflepuff who won the Quidditch Cup, although Hufflepuff scored more than Slytherin, but as long as Slytherin won the last game, they could surpass Hufflepuff to win the Quidditch Cup, but they were defeated by Gryffindor. Hufflepuff won the Quidditch Cup because of Gryffindor.

"Anyway, this year belongs to Hufflepuff after all. Ernie said cheeringly.

Field and Cedric smiled silently. This year's Quidditch tournament was a tough one, with Hufflepuff's tactics completely restrained by Slytherin, and the lack of quality of the players and Field's revamped broom began to malfunction. This year's Quidditch tournament was in limbo for a variety of reasons.

"Seid, you're going to have to find a way to get a new batch of brooms next year, or you won't have to think about the Quidditch Cup. Field said.

"Field, why don't you sponsor Hufflepuff, you're going to make a lot of money this year. Cedric suddenly looked at Field.

"Please, Seid, you know that although I make a lot of money, I also spend a lot of money, and all my savings have been used up for this year's trial. Field said with a weeping face, and before Cedric could speak, he ran after Rolf and Ernie.
