On Wednesday, William went to the auditorium to preview his homework as usual after class, and there were frequent discussions in low voices everywhere in the auditorium.

William was flipping through a book called "The Brain of the Magician". The author of this book, Cobb Nicholas, is an aristocratic magician in the United States. He is a magician who loves human experiments, especially brain experiments. If he is in the Muggle world, this person will definitely be a top scholar in the field of brain nerves in the medical field. This book starts from why Muggle can become a magician and gradually discusses how magicians should enhance their abilities. And William agrees with his main point.

The development of the human brain allows people to have different abilities. Many Muggles have created great miracles in history. The development of the human brain will make some people smarter, while very few people will have that special power, supernatural power, which cannot be explained by science. For magicians, the level of brain development of magicians is not necessarily higher than ordinary muggles, and magicians are not necessarily smarter than Muggles. However, the power that magician owners Muggles do not have. Since ancient times, many magicians have given up their identity as magicians and joined the Muggles world, and married Muggles, causing the magic-carried "gene" to be passed down in the Muggles world. For thousands of years, with the increasing population of Muggles in the world, more and more people have such abilities. It can be said that most Muggles have magical "genes" in their blood.

Magicians have magic powers inherited from blood. Muggles have abilities, which can be said to be a blessing from God, because the chance of obtaining a magician-like mind is too small, much less than one in ten thousand. The nobles oppose Muggle bloodline because they believe that hybrid blood will weaken the power of the next generation. They believe that the magic energy contained in Muggle blood is not pure. If this continues, one day there will be a large number of squints, and there will be no future in the magic world. The reason why mixed-race wizards like Voldemort is so powerful is inseparable from the inheritance of Slytherin in his blood.

If a magician wants to enhance his abilities, he must constantly develop his potential, develop his brain, and constantly break through himself in desperate situations.

The rest of the content in the book is mainly about Muggle wizards, and even talks against Muggle, which run contrary to William's philosophy. This is an academic work that promotes aristocratic theory, providing some theoretical basis for the aristocratic opposition to Muggle wizards. Even if many of the content in the book makes sense, it does not mean that it is correct.

Whether the magic world can survive William does not seem to be what kind of blood flows in his blood vessels. A powerful magician will never rely solely on the power in the blood, but more on his heart, his will, and his ideals. The nobles should have played an active role in the changes of the times, accepting Muggle wizards and establishing cooperative relationships, rather than resisting Muggle, opposing Muggle, and being self-satisfied. This is exactly what William hopes to change, turning this somewhat decaying and profit-first magic world into a world where Muggle and pure blood understand each other.

The biggest enemy in the magic world is not Muggles, but themselves.

William closed the book and let out a long breath. Whenever he read this kind of book, William felt that the burden on his body was very heavy. He let the pure blood accept Muggles and Merlin's beard! At this time, the sound of wings flapping came from the auditorium, and it was time for the owl to deliver the letter.

William didn't care. Avi and Bill rarely delivered letters on Wednesday. But today was an accident, and a red envelope fell in front of William. William opened it curiously:

"Dear William, before telling you this, I hope you know that Bill and I will love you as always, and our love for you will only increase. My mood is very excited now, my child, I still remember how happy I felt when I learned that I had you! William, you have a sister! We decided to call her effy. Love your vi and bill forever."

William couldn't believe his eyes, his heart was beating very fast, he felt that he could not think anymore. William pinched the letter paper with his thumb and index finger.

"effy? My sister? Sister!" William stood up suddenly and muttered to himself.

The people around him were startled and the auditorium suddenly became quiet. William didn't look at it, and he kept muttering "effy" repeatedly, as if he was the only one in the auditorium.

William's eyes were wide open, his hands were shaking, his face showed a surprise expression, and his mouth was half open. He turned around and wanted to leave the auditorium, but he forgot the existence of the stool and tripped over the stool. No one in the auditorium laughed, but in fact they were very scared, especially Hermione and the other Malfoy beside William. This was too "William".

"William, are you okay?" Hermione rushed over and helped William up. Malfoy also stood up, but he didn't say anything.

"effy, Hermione is effy! Called effy!" William stared at Hermione in surprise, grabbed Hermione's arm tightly, making Hermione painful to grab hermione's pain.

"Who is effy?" Hermione didn't blame William, she asked nervously.

"Brother, are you okay?" Ron asked.

"What happened at home?" Malfoy interrupted

"Oh no, it's not what you think." William laughed and shook his head, looking a little crazy

The eyes in the auditorium stared at William in unison, very quiet.

"Who else can it be, woman?" There was a sound coming from somewhere. The sound was very small, as light as a needle falling on the ground. However, in this occasion, even if the needle falling on the ground, it was very clear and loud.

William suddenly transformed into Longkinus, waved his hand and saw a white light, followed by another sound of breaking through the air. The speed was too fast, and there was not even a blink of an eye. Suddenly, a man flew out of the table and fell to the side. Many people screamed. The person who flew out didn't even have a chance to scream. The poor man was Justin. At this time, he was already unconscious. William was still taking care of him and didn't take any heavy measures, but it seemed that he would have to sleep for a day or two.

"William!" Hermione covered her mouth. She didn't expect William to be so irrational. However, the next second she was like she was frozen, and the whole auditorium felt very cold. William's hair was messy, and his clothes were not neat after falling down just now. His face was tight and his muscles were tight. William completely released his momentum. He was very angry now. Hufflepuff people wanted to come out and shout, but no one dared to look at William's eyes. At this time, William's eyes were glowing with a faint golden light. Everyone saw it. William's face was completely gone without the excitement he had just now. The expression was the anger of "Don't mess with me". William held Longkinus tightly, his eyes swept the entire auditorium flat, and many people swallowed their saliva in fear.

Hermione shivered in fear. She stretched out her hand to go to Ray William. William ignored him and threw away Hermione's hand and walked out of the auditorium. Hufflepuff's men hurriedly sent the guy lying on the ground to the school infirmary. At the same time, Qiu Zhang's figure disappeared on the long table of Ravenclaw. Qiu Zhang didn't care about Hermione or others at all. As soon as William went out, she chased him up. Why do she care so much at this time?

"What the hell is going on? I was so scared just now." Ron felt his head was blurred

"I don't know, I feel this way. It's better to calm William down now," Harry said
