Chapter 61: Petrified Charm

　　 With the coming of November, the weather became very cold almost overnight.
　　 The mountains around Hogwarts Castle looked gray and covered with snow and ice. A thin layer of ice began to form on the surface of the Black Lake. And when they walked out of the Slytherin common room every morning, there was frost on the ground outside Shimen.
　　 They had to add thick clothes to keep out the cold.
　　 And Matthew Wickfield has also drastically reduced the number of trips to the library or the responsive house.
When he’s okay, he prefers to sit in those soft armchairs in the Slytherin common room, while he is burning by the fireplace, reading a book, or writing homework... Whenever he doesn’t understand a place, he can still stand up to the people around him. Grade students ask for advice.
　　 Just like Hermione Granger’s previous
prophecy
, since the end of Halloween, Professor Rozier once again
no trace
... The official explanation is that her injury has not healed.
　　 And the principal of "Gellert Grindelwald", every morning, lunch and dinner, will appear on time in the main guest seat of the auditorium.
　　 Perhaps Hermione’s previous
guess
was correct. Professor Grindelwald did not have all the authority of the Headmaster of Hogwarts. He could not stay at Hogwarts for long...
　　 And now that they appear in front of them every day, they are dressed up by the Vice President Professor Rozier.
　　 But Matthew's "prophecy" was not wrong. Although the principal who appeared in front of them every day was likely to be a fake; but the "true murderer" who hid in the darkness was still afraid of him, and he dared not create new attacks.
　　 Except for the trivial little "interlude" on Halloween, the castle is peaceful.
　　……
　　Professor Rozier "has not healed from his injuries", so the first grade defense against the Dark Arts class is still temporarily taught by Professor Troka.
　　 Their level of defense against the Dark Arts, under the guidance of Professor Troka, began to improve little by little.
　　 It’s another Friday afternoon, and another Defense Against the Dark Arts class—
　　 "Among all the protection spells, the'petrification spell' is undoubtedly the easiest one... and it is also one of the few, suitable for you little wizards who are new to magic!"
　　 "You know, the younger the wizard, the less easily the magic in the body can be controlled...Blind contact with those powerful protection spells, even if you can learn it with extraordinary talents, the possibility of accidents is great!"
　　Professor Troka's voice is still hoarse, but his face has been pretty good recently, at least better than when he first came to Hogwarts.
"At the same time, the petrified spell is one of the few spells that will not cause any harm... Most of the time, in the face of those plausible'enems', the petrified spell is the spell that should be used most... When the opponent is not an enemy, cause unnecessary damage to the opponent."
"Professor Rozier should have taught you that the mantra of the petrification mantra is:'Petrificus Totalus'! But don't despise it just because it is the simplest protective spell... Remember, you want to use any one proficiently Protection spells require a lot of practice!"
　　 "The stress is on the first P and the second T respectively. Please pay attention to the pause between the two words for about half a second... Don't make a mistake!"
　　Professor Troka’s Defense Against the Dark Arts class is undoubtedly more popular than Professor Rozier. Of course, this is not because of academic level, but Professor Troka is much more easy-going than Professor Rozier, and the atmosphere in the classroom is much better.
　　 "The effect of the petrification spell allows your target to be restrained and unable to move within a certain period of time... Of course, the target of this spell can still maintain the function of the body, so it will not cause any harm."
　　 "In addition, the petrified mantra also has a curse, the mantra is ‘Finite Incantatem (FiniteIncantatem)’. When you realize that the goal of your petrified mantra is wrong, please use it as soon as possible!"
　　 "Remember, the accent of Incantatem is at the end..."
　　 Actually, this is the third lesson after they started learning the petrification spell.
　　 It's just that Professor Troka is still the same as in the transfiguration class, some "talking" repeatedly repeating these details, so that they can remember.
　　 They were also divided into two groups for actual combat exercises.
　　 Matthew’s partner is Draco Malfoy.
　　 He raised his wand, pointed it at Matthew, and shouted, "All petrochemicals!"
　　 There was a sudden explosion at the end of his wand, and poor Malfoy was recoiled by a blow and hit a wall behind him.
　　 Malfoy fell to the ground, groaning in pain.
　　 "Malfoy! Pause for half a second between the two words! Don't forget this!" Professor Troca yelled while helping Malfoy up.
　　 Poor Draco Malfoy, who has nearly two months less courses than other students, is now almost in the tail of the crane in every course.
　　 "Wickfield, you come and try!" Professor Troka pointed to Matthew, UU reading www.uukanshu.com ordered.
　　 Matthew raised his wand and pointed it at Malfoy:
　　 "All petrochemicals!"
　　 A faint red light shot from the end of Matthew's wand, and then accurately hit Malfoy's body.
　　 I saw Malfoy's arms slap against his sides, his legs standing upright, standing straight. His whole body became stiff, and he swayed on the spot a few times before he fell to the ground with a plop, looking like a wooden board. At the same time, his face, the upper and lower gums were locked together, speechless, only his eyes were turning.
　　 "Good job, Wickfield!" Professor Troka praised:
　　 "Now, unlock the petrification curse on Mr. Malfoy!"
　　 Matthew raised his wand again: "The curse stops!"
　　 I saw another red light.
　　 This time, Malfoy's stiff body quickly recovered in an instant. He quickly got up, gasping for breath.
　　 "It's perfect!" Professor Troca also gave Matthew the curse, which was highly praised.
　　……
　　 About ten minutes later.
　　Professor Troka looked at his watch, and then said: "Okay, this class is over, I hope you will practice hard after you go back!"
　　 "The feeling of being petrified is terrible!" Malfoy whispered as he packed his wand.
　　 "Don't be discouraged, you were very close to success just now." Matthew responded.
　　 "By the way, Wickfield!" Professor Troca called Matthew's name again:
　　 "You stay alone for a while!"
　　 Matthew was stunned.
　　 "See you in the auditorium later!" Malfoy waved, and then with Crabbe, Gore and the others, walked out of the Defense Against the Dark Arts classroom.
