Kevin, Terry, and Mike stand at Hogwarts train station waiting for the Christmas train home, the biting cold wind accompanied by snowflakes blowing at the students at the train station.

Terry and Mike are also going home for Christmas, and it should be said that most of the Hogwarts students are going home for Christmas. Tyried shivered in the cold wind, he wrapped his cloak tightly, and Mike felt his teeth start to fight! Kevin stood in the cold wind but contrasted with Mike and Terry.

"Oh, Kai... Kevin: Don't you feel cold at all?" Mike easily asked the sentence completely, and he tightened his scarf! Terry looked at Kevin as well, and his eyes looked like he was asking, this question.

"I'm not afraid of the cold, I'm used to sleeping anymore!" Kevin replied casually, it was impossible to say, I'm not afraid of the cold, let the ice and snow come more violently!

Terry and Mike complained with their eyes, we are all afraid of the cold, you are not afraid! Kevin was helpless, and pulled out a glass jar from his luggage, which was originally used to hold chocolate, I have to say, Kevin likes to eat chocolate very much, and always carries two on his body every day.

Kevin pulled his wand out of his sleeve and cast a spell on the jar, and a flame half a fist sized flame appeared in the jar, burning in the air as if burning air. Kevin closed the lid and handed it to Terry and Mike, who immediately grabbed the glass jar and began to warm it up.

"You can do this, why didn't you get it out sooner?" Mike spat at Kevin.

"100 Practical Little Magics, if you like it, you can buy it! Also, you can't rely on others for everything, you have to cheer yourself up!" Kevin said helplessly,

As a Ravenclaw, Kevin does not underestimate Terry and Mike, Terry is good at Transfiguration, and Mike is good at potions! Although he is not as good as Kevin now, Kevin's lead is entirely due to his fine magic control, and his magic power is greater than that of young wizards of the same age! Moreover, Terry is a pure-blood family, and there is a family inheritance! Mike is a half-blood, and his father works in the Ministry of Magic and the Department of Political and Legal Affairs.

A figure walked towards Kevin from the group of students on one side, her shaggy hair already telling everyone who she was, Hermione Granger.

"Hey, Kevin, hello, Mr. Bout, Mr. Koena. ”

"Hello, Hermione!" "Oh, hello, Miss Granger. Mike and Terry replied at the same time. After speaking, the two of them walked to the side, talked around the tinder, and glanced at Kevin as they walked, Kevin rolled his eyes and glared at them helplessly.

"Hey, Hermione, what's the matter with you?" said Kevin,

"Well, Harry and I had a problem recently, so I thought I'd ask you. Can I ask you?" Hermione asked, looking at Kevin,

"What's there that can stump our Miss Know-It-All?

Hermione was embarrassed, "Do you know the Philosopher's Stone?" Hermione looked at Kevin, a little cautious.

Kevin quickly recalled the book he had read, "The Philosopher's Stone, also known as the Philosopher's Stone, is an extremely powerful alchemy product, and can also make elixirs, and it is reported that the last Philosopher's Stone in the world belongs to Nicol Lemay, who is now almost 600 years old! That's all I know." ”

"No wonder I couldn't find him in Modern History of Magic and The Great Wizards of the Middle Ages. Hermione muttered, and Hermione came back to her senses, "Thank you Kevin, I know how to find information, thank you." With that, she said goodbye to Kevin and returned to her roommate.

Kevin frowned, Philosopher's Stone, what are they going to do to study such a powerful alchemy product? Kevin was very puzzled, Hermione said that if she wanted to understand, Kevin believed it, but Harry Potter wanted to understand, it would be different! As far as he knew, although Harry Potter was very talented in magic, he was not easy to learn.

"Eh, what is the Gryffindor Miss Know-It-all looking for from you, and what is your relationship?" As soon as Hermione left, Terry and Mike surrounded them with gossipy faces. Kevin rolled his eyes at the two of them again, and just as the train was coming, Kevin walked towards the car with his luggage.

Once in the car, Kevin picks up the books he borrowed from the library, blocking Terry and Mike from continuing the conversation. The two of them sat across from Kevin, muttering some of their conjectures, looking at Kevin as they spoke. Superman's five senses made Kevin hear their words clearly, and Kevin had to use a "closed earbud to listen" to himself to avoid the poison of the two.

Kevin calmed down, thinking back to Hermione's question. Philosopher's Stone ...... Kevin thought about what had happened in the past half a semester, and his eyes lit up! The Philosopher's Stone is at Hogwarts, and the three-headed dog is used to guard the Philosopher's Stone! Only the magic props of the Philosopher's Stone can dispatch the three-headed dog. So, Professor Quirrell was aiming for the Philosopher's Stone, so he introduced the trolls to Hogwarts and lured Professor Dumbledore away. Professor Snape noticed it, so he went to stop it, and was wounded in the leg by the three-headed dog. The more Kevin thought about it, the brighter his eyes became. But why did Professor Quirrell do anything to Harry Potter, why did Dumbledore let a dark wizard come to Hogwarts to teach? Kevin didn't believe that Dumbledore didn't see anything, and the older people get, the more shrewd they become. After figuring out some doubts and washing them again, Kevin was almost scratched to death by his curiosity.

Running the magic, Kevin calmed himself down. If you can't figure it out, you don't want to, the truth will always appear.

Letting go of the doubts in his heart, Kevin looked at the book in his hand seriously, only to find that he was holding the book "The Origin and Development of the Demon Text" that Hermione reminded him of that day, and the train was whining and whining towards London.
