The Weasley brothers, as twins, even their mother Molly can't tell who is George and who is Fred.

At this moment, one of them hugged the other who had fallen to the ground, trembling and crying out to Rorschach for help.

I saw Weasley on the ground, pale and bleeding from the seven orifices, and the blood had already formed a pool of blood around his body.

The other students moved out of the way of the Weasley brothers so that Rorschach could see their plight.

The students were well aware of the Weasley brothers' pranks, but no one would choose to betray them, firstly because of their unity, and secondly because they spent more time with the Weasley brothers.

Weasley, who cried for help, had blood on his hands, and he looked at his brother in horror and held out his hand to Rorschach in need.

However, Rorschach looked at the Weasley brothers with interest, circled around them, and said, "You made a mistake! ”

Rorschach then raised his voice and asked the other students, "Do you know what went wrong with them?" ”

The students shook their heads, saying they didn't know.

Rorschach reached out and split the blood from the ground, gathering it into a blood ball the size of a human head, floating around the Weasley brothers.

Pointing to the Weasleys bleeding from the Seven Orifices, Rorschach said, "First of all, we have to understand a truth, the bleeding of the Seven Orifices and death are two different things. Typically, blood will only come out of these areas if you have suffered a severe crush injury. In the Muggle world, serious car accidents and industrial accidents are usually the main focus. ”

"But just now, what happened here?"

Everyone shook their heads, and even the Weasley brothers were interested, remembering the contents.

"The second point is that a person's blood volume is about 8% of their body weight, and if they weigh 60 kilograms, then the blood is about 4,800 to 5,400 milliliters. Now look at this blood cell, how big is it? ”

Weasley, who was on the ground, looked at the blood he was shedding and said, "About two quarts?" ”

The imperial unit is about 1136 cubic centimeters per quart. Rorschach shifted in his mind for a long time before he figured out how much.

"Use metric units in the future!"

After reminding Weasley, Rorschach said: "When the blood loss reaches 15% of the total blood, the body's compensatory machine is activated, and 30% of the human body will have symptoms of paleness, pale lips, cold sweat on the skin, cold hands and feet, weakness, shortness of breath, and rapid pulse." 50% reaches the theoretical limit of human blood loss, at which time the human pulse is almost gone, the blood pressure is almost undetectable, the sinus pulse of the heart stops, and after 30 seconds, the breathing stops, and the brain is extremely hypoxic. ”

Looking at Weasley on the ground, Rorschach said, "Actually, you were dead before you called for help, Mr. Weasley." ”

Forming a ball of blood, Rorschach handed it to the Weasley brothers, saying, "Write a paper of no less than two thousand words about today's lecture and your pranks." Give it to me next Monday. As for the rest of the students, just take a class note. ”

After class, the other students left happily, the novel knowledge points at least excited them, and after class, as soon as they left the classroom, the blood ball in the Weasley brothers' hands exploded on its own, and the blood evenly stained every inch of skin on the two of them, making the Weasley brothers the new talking point at Hogwarts.

Not long after class, Snape pushed open the door and hurriedly walked in, he said unceremoniously to Rorschach, "You'd better take care of Chisya, she just hurt my student!" ”

"Would you like to hear what your students have to say?"

Rorschach reached out and summoned Chishya to explain to Snape.

"He said I was a mudblood!"

Qianxia's words made Snape unable to ask any more questions.

The name of the mudblood made the former Snape lose Lily Evans, which also became an eternal pain in his heart.

So anyone who dares to say this name will be met with Snape's absolute disgust. As for whether the Slytherin student who was shot said or not, then Rorschach is asked. Slytherin students wouldn't admit it anyway.

Looking at Chisya, Snape was silent for a moment and said, "Huh...... Not an example! ”

With that, Snape turned to leave.

"Hey! Wait a minute! ”

A small cloth bag was tossed from Rorschach's hand, and Snape reached out to grab it, and the bag contained the Philosopher's Stone.

Rorschach said unceremoniously: "I'll go to you at night, I need to get a little potion!" ”

Holding the Philosopher's Stone in his hand, although his heart was excited, Snape still said expressionlessly: "I will not let you dictate!" Mr. Rorschach! ”

I took out a mushroom and threw it over, and the pale orange mushroom still had a red spot on it, which looked very abnormal.

"This thing can be used to configure the life potion you have drunk, and it can also replenish life force when eaten empty, and I have many other magical herbs......"

Tearing off a small piece of mushroom and sniffing it under his nose, Snape put away the whole mushroom and said, "Come early in the evening!" ”

Snape was gone, and Rorschach was getting ready for the next lesson.

In the lower grades, there will be no more cramming education in the upper grades, just let the young wizards recognize the basic tools of the Muggle world, at least not like Arthur Weasley, who learned to make phone calls and was excited for a long time.

Hermione was the last one to appear, hiding behind the curtains while Rorschach was talking to Snape, waiting for the young wizards to arrive before pretending to be late.

Ron took a mechanical camera, took a picture of everyone, and then washed it out in the dark room as instructed.

Looking at the immovable photo in his hand, Ron excitedly said that he would send it to his father.

"Oh yes! It's so much fun! The poor Weasleys are so fond of Muggle stuff that they are ready to move to the Muggle world? ”

A very unpleasant, arrogant-sounding sentence came out of Malfoy's mouth on the side.

Hearing this, the other little wizards who were originally interested in mechanical cameras also gave up their plans to come and try.

Rorschach looked at Malfoy, who was hanging from his right arm in a bandage, the injuries he had suffered in Hagrid's magical biology class had not healed, and the lesson had not been enough.

"Malfoy, you have a problem with my teaching!"

Rorschach's warning didn't make Malfoy relent, he just said to the people next to him mocking the Weasleys.

Suddenly, Malfoy couldn't say a word, and even his mouth disappeared from his face.

A panicked Malfoy opened his jaw desperately, but only let out a whine, which caused those around him to avoid him.

Upon seeing Rorschach, Malfoy stopped panicking and whined at his face.

As soon as Rorschach reached out, his mouth returned to Malfoy's face.

However, Malfoy was enraged, and he said to Rorschach, "If only my father knew!" He'll get Dumbledore to kick you out of Hogwarts! ”

"Oh...... And then what? ”

"What?"

Malfoy suspected that he had heard the wrong thing, that this Muggle professor didn't care about his father, who was a member of the board of trustees, or that he didn't know?

Malfoy then emphatically said, "My father is a school trustee!" He can get Dumbledore to kick you out of Hogwarts! ”

"Mr. Malfoy, I'm asking you how you are going to take revenge on me! Instead of using your father to make these useless threats! If you bring my father with you in every sentence, it will only make people think that you are a waste who has achieved nothing but my father!

Even if you pull out your wand and cast a curse on me now, I'll look up to you! ”
