Chen Yu seems to have returned to his youth, studying those obscure mathematics, physics, and chemistry day and night, and he doesn't understand and won't ask, and no one asks, only he can study and find the answer by himself, the only difference between him and when he was young is that he no longer learns those mathematics and formulas, but mysterious spells! He was very glad that he had such an experience when he was young, otherwise he would have to be the year of the monkey if he wanted to figure out the basic books of these spellcasters, and he hoped that he would not understand the question. No kidding, with a speed comparable to a snail, he will figure it out by the time it arrives, not to mention, he is a little allergic to those "dong dong" sounds, and he feels uncomfortable when he hears it!

After seven days of studying, Chen Yu finally ate the three books left by Dong Dong, which made him unconsciously relieved, at the beginning, he studied extremely hard, so hard that he wondered if his IQ had decreased, but fortunately, after the first few days of adaptation, the progress suddenly accelerated.

He now has a deep understanding of spells. If you want to cast a spell, you must first know how many spell runes the structure of the spell is made up of. Spell runes are a very esoteric script, and the meaning contained in them is even more obscure, and it is difficult to learn if you are not a master who has been immersed in this way for many years. But if you want to learn spells, you don't need to learn runes, you just need to know what the runes that make up this spell look like, and when you use it, you can cast a spell by drawing a scoop according to the gourd, and the degree of thinking activity determines the speed of rune condensation, which also determines the speed of spell casting, such as Chen Yu, with his perfect level of thinking activity, he can condense forty-four runes in one second!

After figuring out what spells were and how to learn them, Chen Yu felt that he was a beginner and could move on to the next step, so he shouted into the air, "Knock knock!" ”

I don't know what principle the iron puppet Dongdong relies on, but Chen Yu knows that as long as Dongdong is in this castle, no matter where it is called, it can hear it and arrive at the first time, of course, with its speed, you don't expect how fast this "first time" is.

About ten minutes later, an annoying "dong dong" sound came from far and near, and dong dong really came!

"Boy, what do you call me for, do you know that I am cleaning the room for the great and beautiful master?" Dong Dong leaned against the wall, squinted at Chen Yu, and said: "If your question is still as in-depth as before, I will refuse to answer, it is too disrespectful, you know, I am a servant with status!" ”

"I've learned the three basic books you left behind, what are you going to do next?" Chen Yu said for a long time: "I don't know if this question is considered deep?" Knock Knock Adult? ”

"Impossible! It took me three years back then, uh-" Knock Knock immediately covered his mouth, whew, so dangerous, he almost told his black history, "Ahem, I mean, you probably didn't just read it and didn't understand it at all, right?" That's not going to work, I'll tell you—"

"Just tell me what to do next!" Chen Yu interrupted Dong Dong, who was about to make a tirade, if he let it continue, he didn't know when he would have to talk about it, he didn't have so much time to waste.

"Ha, you kid who doesn't know the hearts of good people, I don't listen to my free advice, don't look for me when the time comes!" Dong Dong was very angry, angry that his kindness was regarded as superfluous, and even more angry was that this boy who fought five scum actually dared to interrupt his own speech, this is the master's patent!

Dong Dong stretched out his hand and pointed, and two more books flew from the bookshelf to its hand, it tore open the light film on it and fell in front of Chen Yu, and said in a bad tone: "If you don't learn it, don't call me, I won't pay attention to you if you call me, I'm a servant with status, not everyone is qualified to call me, hum!" ”

After Dong Dong finished speaking, he left arrogantly, leaving behind a series of "Dong Dong Dong" sounds.

Chen Yu didn't bother to pay attention to Dong Dong, and picked up one of the two books, this book has a fiery red cover, and the four corners of the cover are decorated with metal patterns, which looks very high-grade, I don't know how much stronger than the previous three, just looking at this cover makes people look forward to it, not to mention that this book is called "The Art of Hilphas!" ”

Although Chen Yu didn't know what "Hilface" was, that didn't prevent him from knowing that it was a skill book! To be honest, his heart was a little excited at this time, after all, this was the first skill he learned, and the most important thing is, if he learned the skill here, then, can he use it in the real world? If it did, what would the world look like? Probably endless chaos!

Chen Yu stopped thinking nonsense, opened the book and looked at it seriously.

"It turns out that the technique of Hilface is the fireball technique!" After reading this skill book, Chen Yu realized that this is a skill book of fireball technique, and there is nothing to say about this skill, which is to attract the power of heaven and earth to send a fireball to the target, and the damage depends on the physique.

Since the fireball technique is a primary skill, it is only composed of thirteen runes, and with Chen Yu's perfection-level thinking activity, theoretically speaking, he can launch three fireballs in one second, of course, he also knows that this is just a theory, in fact, he is not even sure if he can learn it now.

It took him half an hour to memorize all the runes and structures of the Fireball Technique, then stretched out his hands, closed his eyes, and began to condense the runes needed for the Fireball Technique according to the method introduced in the basic book.

The moment he closed his eyes, his thoughts extended like needles along a certain medium floating in the air, and the higher the activity of his thoughts, the more thought needles were separated, and the limit was forty-four, and since it was the first time, he only divided thirteen. And that medium is the power of heaven and earth, of course, Chen Yu prefers to call it magic! After the mind strung together the passing magic, he controlled the mind to bend the string into a required rune.

Since it was the first time he had done it, it took him nearly a minute to condense the runes needed for the Fireball Technique. After that, he controlled the runes to form the structure of the book according to the writing of the book.

At the moment of composition, he suddenly felt that Dao's hands were a little hot, and when he opened his eyes, he saw a fist-sized fireball suspended between his hands, and the heat came from it.

[System Prompt: Congratulations, you have learned your first skill, the Art of Hilface!] 】

"Well, it turns out that the skill is not so difficult to learn!" Hearing the prompt of the system, although Chen Yu was a little surprised, he felt that it was reasonable, after all, he was a genius!
