Dragon's blood is indeed a good thing, and after getting the dragon's blood, Ryan made a special trip to the world with extraordinary power that he mastered, and exchanged the dragon's blood for a lot of benefits.

For example, he exchanged a lot of high-quality alchemy raw materials from Teacher Luo Zhen, got several good magic weapons from Uncle Jiu, and finally exchanged the destruction mushroom and frozen mushroom he had just made from Dave. In short, this bottle of dragon blood made him full of harvest, and at the same time, it also provided enough foundation for his next alchemy research.

Just as he was indulging in all kinds of new knowledge, the weekend book club meeting began. Today's book club has two new faces because of the previous recruitment: Ravenclaw's freshmen Main and Celia.

"Why are we so few newcomers?" Ryan asked Hermione, who was standing next to her, curiously.

"No way, we need people who love learning, love knowledge, and have a sense of tolerance and a certain tendency towards collectivism, and there are not many such people. After all, when we choose members, we have always preferred not to recruit people or never recruit people, otherwise if we let them go, your admirers will fill this classroom this year. ”

"You're right, it's better to have less than to overuse. Ryan nodded in approval.

Soon everyone began the daily Q&A activities of the book club, and as new students, Main and Celia quickly adapted to the atmosphere with everyone's help, and Ryan found that their current behavior was no different from that of the old members.

It's just different from usual. A while ago, because Ryan was going to play, everyone held back their curiosity and didn't ask Ryan too much during the free question time. And now the first race is over, and the second race is still two months away. In this case, people began to ask Ryan about some of the things they had been wanting to ask before.

In order to avoid everyone being unable to hear clearly, Ryan asked everyone on the field who wanted to ask questions to write down the question they wanted to ask the most on a slip of paper, and then he would give a unified answer. Soon, a handful of notes were handed to him. Ryan looked at it, walked to the back of the lectern in front of their activity classroom, and began to answer them one by one.

"I think most people are asking me how I got past that age line and what exactly I used to beat the dragons in the fight. Actually, I can answer these two questions together, and that is alchemy. I used alchemy to achieve these goals. ”

"But I've never seen alchemy in the Hogwarts curriculum. Justin asked aloud. "So what should we do if we want to learn?"

"First, Hogwarts has alchemy. "But this course is only offered in the sixth grade, and it is required to apply to the school after obtaining an O in the four courses of ancient magic, arithmetic divination, transfiguration, and potions in the fifth grade, and the school will only offer alchemy." ”

"Oh my God!" "How is this possible?" "I think only the boss and the eldest sister can do it here. There was a sparse argument from below, and Ryan quickly pressed down with his hands to signal everyone to be quiet, and then continued: "Second, I would like you to share the secrets of alchemy, but those who are interested in learning this subject must be recognized by me in the four courses such as Ancient Magic. ”

"Why do you want to do this? Can't you just learn it?" Fred asked.

"Unfortunately, no. Ryan said categorically: "Because once the foundation of alchemy is not strong, the harm will be very great, and it is likely to threaten everyone's life." So, I'll show you how you should know. ”

With that, Ryan took out two pieces of wood from a pile of worn furniture in the corner of the classroom, then took out a pre-mixed magic potion from his bosom and began to write and draw on it. Everyone in the classroom was drawn to this as well.

Ten minutes later, both pieces of wood were painted with runes. Ryan took out two crystal balls the size of ping-pong balls from his bosom and set them on the tops of the two pieces of wood, and then he placed them on the podium and said, "Now, come up and check what is the difference between these two sticks." ”

One by one, the members of the reading club below began to come up to the stage to inspect the two sticks, but they didn't see anything. After checking it, George said, "Don't tease us, I just saw you make these two sticks in the same way." The ingredients are the same, and even when I hold them in my hand, I can feel the magic emanating from the two of them. So I feel like they should be the same. ”

"Really?" Ryan asked the audience, "Do you think so too?"

As a result, most of them nodded, and the corners of Ryan's mouth rose slightly when he saw this scene, and then said, "Then Neville, please come up and help me." ”

Neville walked up a little shyly, and Ryan asked him to pick up the two sticks on the stage, and then said, "Throw them on the ground." ”

"Huh?" Neville opened his mouth in surprise. However, he quickly followed his words, and when the two sticks hit the ground at the same time, one made a metal crashing sound on the ground and bounced twice. The other one fell to the ground like glass and shattered into large and small pieces.

"Here's what's going on. Fred's shout spoke to everyone's heart, after all, everyone had just seen that Ryan was doing exactly the same thing on the two sticks.

"That's what I'm talking about when it comes to alchemy, and the two sticks look similar, but they're actually different. After that, there are slight differences in many runes on the two sticks, but if you are not familiar with ancient runes and arithmetic divination, you will not be able to see the difference here. ”

After speaking, Ryan picked up the fragment on the broken wooden stick and compared it with the other intact wooden stick in the same place and explained, "You see, the angle of this rune is greater than that of the other, because the surrounding wood texture is different, resulting in a difference in the calculation factor of spell distribution, and at the same time inserting Jaber??" Ibn?? Hayan's third formula for the balance of magic in the Book of Balance - "

When it came to what he was good at, Ryan began to gush on the stage, and he continued to talk for seven or eight minutes before concluding.

In this case, even if it doesn't feel like much, it can still produce a completely different effect. Okay, that's all for my explanation, do you understand?" At this time, Ryan glanced at the audience, and found that the people below were either as straight as Hermione, and their faces were confused without understanding. Or, like Neville, he just fell asleep and didn't listen at all.

"Okay Ryan, we know the importance of the foundation. Zhang Qiu stood up at this time and said. "You're right, alchemy is indeed not something we can learn at our current level. At this stage, in addition to the knowledge in the textbooks, it is only right that we understand those ancient magic texts. ”

"That's true. "That's right. "Sure enough, we were a little arrogant because we had learned something. "Everyone's voices came from below.

After that, until the end of the meeting, everyone was learning the textbook knowledge or learning some new runes, and no one asked to learn alchemy.

"It seems that this time everyone understands that the beginning of learning knowledge is to have a humble heart in front of knowledge. In this way, this meeting is still very meaningful. Ryan thought happily as he returned to the tower with the Gryffindor students after the party.
