Chapter 145 The holiday is over.

The notebook that Professor McGonagall sent was actually written by Dumbledore?

Mike was so excited that he almost jumped up when he found this. As Dumbledore is currently recognized as the strongest white wizard in the wizard world, there is no need to explain how valuable the notebook he wrote personally is.

Excited Mike couldn't wait to flip through the Transfiguration notebook.

The notebook was not thick, and Mike had read the entire notebook in one morning. But what disappointed Mike was that this notebook should be the experience notes written by Dumbledore when he was studying Transfiguration in school. Most of the records in it were some basics of Transfiguration, and there was no advanced knowledge that Mike expected at the beginning.

It can be seen that Dumbledore was definitely an avid fan of Transfiguration for many years. In addition to the Transfiguration class notes, the notebook also recorded many anecdotes about Transfiguration.

For example, the notebook clearly recorded that Transfiguration was actually a simple version of alchemy invented by an alchemist for combat and daily life at the beginning, but after being supplemented and expanded by countless wizards in later generations, Transfiguration has been separated from the alchemy system and has become an independent spell subject.

Although this notebook cannot make Mike's strength soar in a short period of time, many tips recorded in it have benefited Mike a lot. There are even some training methods that can improve the accuracy of transformation in the long term.

But these methods require unremitting training, and Mike can only take it slowly.

Compared with the long-term Transfiguration Notes, the "Flame Master's Guide" given by Professor Flitwick seems a bit simple and violent.

The "Flame Master's Guide" series of books were all written by Ace-d-Newgate, who was called the Flame Master in modern times, with the help of his father Edward Newgate.

Edward Newgate died before this book was published, and Ace-Newgate also died a few years after the book was published.

When this book was first published, it caused an uproar in the entire European wizarding world. Before that, although many powerful wizards understood the power of the fire spell and often used it in actual combat, no one was willing to teach this knowledge to ordinary wizards.

Therefore, the "Master of Fire Guide" became a sacred book for ordinary wizards, and Ace Newgate and his father Edward Newgate were both given the title of Master of Fire.

But if you think that the "Master of Fire Guide" is a cheap civilian welfare, you are wrong. In fact, the Newgate family sold the "Master of Fire Guide" at a very high price. A set of seven books costs a total of 1,000 gold galleons, and if you buy them separately, you need 200 gold galleons per book.

The Newgate family has made a lot of money from this set of books in the past few decades. Hogwarts discussed with the Newgate family shortly after the book was published to include the "Master of Fire Guide" in the school library, but was rejected by the Newgate family because doing so would affect sales.

After learning about this history, Mike couldn't help but curl his lips. It was because the headmasters of Hogwarts over the past few hundred years were relatively gentle. If it was Ms. Ravenclaw who was still in office, the Newgate family would probably have died out long ago.

But even though it is so expensive, the "Flame Master's Guide" is worth the money.

This set of books records in detail the various variants of the use of the fire spell, including the explosive fireball and incendiary fireball that Mike has used.

This set of books gave Mike a lot of inspiration. Before this, Mike was a fireball maniac who only knew how to use fireballs to blow people up. But after reading this set of books, Mike really understood the art of fire.

The damage that fire can cause is not just burning and explosion. Fire consumes oxygen while burning. As long as this feature is used well, it can cause creatures to enter a state of suffocation.

And when the flame burns, it will heat the air. The hot air rises and the cold air falls. The interaction between the hot and cold air will form wind, and the wind will increase the fire. In this way, a good cycle can be formed, which will infinitely enhance the power of the flame.

But these are easy to say, but to do them requires extremely strong control and countless times of practice. Even if Mike's magic control has made great progress after the Ravenclaw Trial, it is not easy to do this.

Mike spent the rest of the Christmas holiday in the Room of Requirement, practicing the subtle control of the Fire Spell so hard that he forgot the time. It was not

until Penelo appeared in front of him that he realized that the Christmas holiday was over.

"Why are you here?" Mike looked at Penelo in surprise and asked, "Oh! Christmas vacation is over, right!"

Penelo saw that Mike looked like he didn't know what year it was and understood what was going on. She sighed and said helplessly, "You started again. You taught me not to practice spells too hard not long ago, but now you practice so hard that you even forget the time.

You can't even take care of yourself when I'm gone. You look so miserable. You must have not eaten on time these days."

Mike rolled his eyes, raised his hand, cleaned up, and released himself, restoring his messy hairstyle and clothes to the way they were before entering the Room of Requirement.

"You're still not happy. You didn't come to dinner tonight. Luckily I brought you some food." Penelope put a few plates of food in front of Mike and said, "Eat quickly. The first round of the duel competition is about to begin tonight, and I have to participate in the competition soon."

While speaking, Penelope's hand stroked her long hair intentionally or unintentionally, revealing the emerald earrings on her ears.

Mike knew what Penelope meant. Although he was hungry, he didn't even look at the steaming food on the table. He went forward and hugged Penelope's waist and said, "My taste is not bad, do you like my Christmas gift?"

Penelope didn't resist Mike's embrace. She took the ends of her hair and circled them around her fingers, thinking. After a while, she said coquettishly, "Well, it's okay."

"Hehe, as long as you are satisfied." Mike was relieved when he saw a smile on Penelope's face. He went back to the table and ate voraciously. "Let me eat a few bites first, and I will accompany you to the stadium in a while."

Penelope didn't say anything else. She came behind Mike and rubbed his shoulders with a smile.

Penelope seemed to have discovered something while rubbing. The strength of her hands suddenly increased. She pinched the numbness on Mike's shoulder and asked in a sharp voice, "Where is the scarf I gave you?"
