Chapter 151: Infiltrator

?　　 After separating from Professor Horace Slughorn, Matthew Wickfield began to go to the greenhouse to have class.
　　 And in the next herbal medicine class, Professor Pomona Sprout told everyone an exciting news
　　 That is, after more than a month of hard work, the pollination of Flor flower has basically been completed.
Although it will take at least several months for them to fully mature... But at least it means that they don’t need to be carefully taken care of every day; they don’t have to be close to the drama in every herbal medicine class. Poisonous pollen, and those stings that store a lot of venom...
　　 After all, wearing a full four-layer thick mask on his face is really too tossing.
　　 And if you accidentally get stabbed by those stings, you have to go to the school hospital to spend a difficult night.
　　 Everyone couldn't help but cheer.
　　 They followed Professor Sprout, left the third greenhouse, and returned to the first greenhouse with only ordinary plants.
　　 They took off their masks and dragon leather gloves one after another, looking at the different kinds of mushrooms in the greenhouse, everyone felt a sense of intimacy inexplicably.
　　 Matthew was picking mushrooms while thinking back to Slughorn’s actions before--
　　 I have to say that he showed too many doubts... Just as Miss Agnes Lestrange reminded me, this Slytherin dean is likely to be a "dangerous person".
　　 "Wickfield!" Professor Pomona Sprout let out a soft cry, interrupting Matthew's thoughts.
She walked over with grief and looked at the mushroom in Matthew's hand: "I should have taught you last semester... When picking mushrooms, pay attention to digging out the entire bottom, otherwise it will cause breakage, easy to infect bacteria, and The preservation time will be shorter...Oh my God, have you all forgotten?"
　　 "Sorry, professor..." Matthew quickly apologized.
　　 Then he lowered his head and began to concentrate on picking mushrooms.
　　……
　　 The weekend is quickly approaching.
　　 In the last potions class on Friday afternoon, the students from Gryffindor and Slytherin gathered in the underground classroom.
　　 At the beginning of this class, as usual, there were about twenty crucibles standing between the wooden tables, and brass balances and pots of ingredients were placed on the table. But before the course started, Professor Slughorn went to Matthew again and talked to him about the Sunday night dinner.
　　 The content of this lesson is a potion called "swelling agent".
　　 Its effect is that it can make the parts of the wizard's body touch it, and it expands rapidly like a balloon, until it rises several times... Honestly, Matthew can't think of any use for this kind of medicine.
　　Professor Slughorn was patrolling back and forth in the smoke, and at the same time, from time to time, he offered some opinions on the work of the students.
　　 Matthew was grinding dry nettles and puffer fish eyes, while instructing his partner (or assistant) Naville to cook the bat spleen... The preparation process of "tumor agent" is a bit troublesome, but the formula is actually very simple.
　　 Ten minutes later, Matthew suddenly noticed that he had boiled the "swelling agent", which was a little thinner, and it looked like a clear soup with fresh water.
　　 It may be that something has made a mistake before, which is quite rare for Matthew in the past.
　　 At the same time, because of Matthew's mind at this time, he put more important things on it.
He was thinking...whether to find an opportunity to overturn the crucible and get a "swelling agent" on his body... Then, using the excuse of being hospitalized in the school hospital, he put it again at the Slug Dinner in Slughorn on Sunday He pigeon.
　　 But if you do that, it seems a bit too deliberate and obvious.
And it’s hard to get any effect... After all, Mrs. Pomfrey’s medical skills, everyone is clear... Dip some "swelling agent", such a small problem, maybe you don’t need to spend a few hours in the school hospital overnight. Can be completely resolved.
　　 More importantly, according to the description in "Magic Potion and Potion", the injured skin will be very, very painful when it is stained with "swelling agent"...
　　 "Neville, Matthew..." At that moment, Slughorn bypassed the crowd and walked to them.
　　Looking at the "clear broth and fresh water" in the cauldron, Slughorn opened his mouth in surprise: "You didn't treat the bat spleen properly..."
　　Navigate was taken aback first, and quickly bent down, removed the cauldron from the fire, and repeatedly apologized to Professor Slughorn:
　　 "I'm so sorry... I forgot..."
　　 "It seems that no matter how smart the little guy is, there are times when a horse strays..." Professor Slughorn didn't blame or criticize them, but just said with a smile over there:
　　 "Mr. Wickfield, don't worry about anything..."
　　 "I see, Professor." Matthew nodded quickly.
　　……
　　 The semester is getting anxious.
　　 As they exchanged a pot of cauldrons with Professor Slughorn. This potions lesson also means that it is over.
　　 When Matthew and Neville left the potions classroom together... Suddenly, they were surprised to find that many students of all grades began to run upstairs along the stairs.
Did something happen?
　　 Finally saw a familiar face, Matthew quickly called her: "Miss Krivat, may I ask, what happened?"
　　 "It's from the principal's office, UU reading www.uukanshu.com" Penello Krivart replied, "It is said that something went wrong over there. Someone tried to break into the principal's office and it even seemed to have caused some loss."
　　 "Let's go over and see," Matthew said hurriedly.
　　 But when Matthew reached the eighth floor of the castle, he found it was crowded with people.
　　 There are many students in each grade, they are talking very eagerly
　　 Matthew squeezed a road with great difficulty. After crowding out the crowd, he suddenly understood why some people would say "An accident happened!"
　　 The real situation, the principal’s office seems to have nothing to lose...but the ugly ""winged beast" outside the office is very tragic, as if it had been severely destroyed.
　　 "Professor Rozier is here," someone said, everyone hurriedly came in line, and at the same time allowed a way.
　　 Principal Waita Rozier didn’t seem surprised, and didn’t even care if anyone broke in... In a sense, she was almost prepared...
　　 Matthew frowned suddenly.
　　 "Did those Azkaban fugitives do it?"
　　 "What are the Aurors doing..."
　　 "The fugitives actually sneaked into Hogwarts..."
The people around 　　 are all curiously discussing.
　　 Matthew didn't stay too much. Soon he turned around and returned to the Slytherin common room.
