The next morning, the sky was drizzling, Augustus, Lilian, and Malfoy were talking about the main points of the fifth-grade promotion exam under a dripping terrace.

Regarding the Potions OWLS exam, Augustus didn't have any extra worries, after the sixth grade, the Potions of this world must be chosen, after all, the two worlds, about the general direction of alchemy, there will still be some commonalities.

The bell rang, the first was Snape's, and when I walked into the smoky classroom, the huge basement was already overcrowded. Even though half of the students who came to class were Slytherin students, they were still in awe of the dean of their house.

"Quiet." Snape said coldly, slamming the classroom door behind his backhand.

In fact, there was no need for him to order everyone to be quiet, as soon as the whole class heard the door closed, they immediately became silent, and all small movements stopped. Normally, the presence of Snape was enough to silence the entire class.

If nothing else, in the first class of the semester, Snape should mention the relevant considerations for OWLS exams, as well as the requirements for entry into the advanced NEWTS class. Augustus twitched his fingers and tapped lightly on the tabletop, waiting for him to offer it.

"Before we begin class today," said Snape, who walked briskly to the podium and looked sternly at them all, "I think it is important to remind you that next June you will be taking an important exam where you will prove how much you have learned about the preparation and use of potions. Although it is true that several people in this class are mentally retarded, I hope that you will be able to barely "pass" o.w.Ls the exam, otherwise I will be very angry. ”

Neville's face was pale, and his eyes were erratic.

Lillian pursed her lips slightly, it was obvious that Augustus would definitely choose to take the NEWTS class in Potions class, which meant that this semester, in Potions class, she must show better grades in order to be selected by Snape.

Malfoy looked at Potter in the corner of the classroom, and with his disgust with Snape, he probably wouldn't be seen again in Potions class after this school year, and of course, it would be boring to rely on Snape's important program to insult Harry.

"Of course, after this year, many of you won't be able to take my classes anymore," Snape continued, "and I'll only pick the best students for my N.E.W.TS Potions class, which means some of us will have to say goodbye." ”

"Today, we're going to prepare a potion that often appears in ordinary wizard level exams: the Tempering Feather, which calms and soothes irritability and anxiety. Note: If you put the ingredients in a so-so way, it can put the person taking the medicine into a kind of dead, sometimes irreversible lethargy, so you need to pay extra attention to your behavior. Lillian straightened up, trying to remember the precautions Snape had described. Ingredients and recipes" Snape waved his wand, "on the blackboard" (and it appeared) "the one you need" he waved his wand again, "in the locker" (the door to the locker he said opened at once) "You have an hour and a half, let's start." ”

Moderator? Glancing at the materials on the blackboard, Augustus took out his wand and pointed at the storage cabinet, moonstone powder, sneezing syrup, and bezoar and other important materials, cleaned up the crucible, first put in the moonstone powder, stirred counterclockwise three times, waited quietly for boiling, and after three minutes, put in two drops of sneezing syrup, weighed three grams of bezoar, cut it into granules, and added to the crucible.

Countless clouds of steaming smoke rose from the basement, and Snape walked up to Augustus, looked down at the pale silver liquid and steam in his cauldron, and nodded in satisfaction, a faint smile passing through his dark pupils.

"Very well, at this time, the potion in your cauldron should be as it is now, with a shimmering silver-white vapor." Snape's slightly penetrating voice echoed through the classroom.

Hermione looked up at the cauldron in front of Augustus, and compared her potion again, except that the color was lighter, it was almost identical.

Snape walked briskly past Hermione, his hooked eyes looking down at Hermione's cauldron without commenting, which meant he couldn't fault anything.

Lilian at this time the color of the potion in the crucible is a little yellowish, indicating that there should be a problem in a certain step, repeatedly check the previous steps several times, and the correct method prompted on the blackboard, if there is no deviation, it should be in the step of cutting the bezoar, its particles are a little too large, which will lead to uneven heating of the whole agent when heating. In this way, he needed to start over, and he emptied the crucible rather angrily, and the corner of his eye suddenly skimmed to a sticky black solid object in the Malfoy crucible, and his mood brightened up in an instant.

Beside Harry's cauldron, Snape stopped and looked down at the cauldron with a terrible sneer on his face. "Potter, what is this?" Moderators. Harry said nervously.

"Potter, sue me," Snape said softly, "do you know words?" Draco Malfoy laughed out loud.

Lillian shook her head slightly, Malfoy could still laugh, didn't he pay attention to the pile he boiled? Medicament?

"Augustus, you have come to sue Sù Potter," Snape's calm face was expressionless, "how did he come up with this pot of waste?" ”

Augustus glanced at the semi-solid potion with dark cyan gas bubbling from the Potter Crucible, "Obviously, the third step is not mixed with sneezing syrup, and the liquid is solidified. The bezoar should weigh more than five grams, resulting in a darker color. ”

"Well, Potter, did you hear me clearly, did you do these two crucial steps that Augustus said?" Snape stared coldly at Potter's face.

Harry lowered his head and whispered, "No." ”

"I'm sorry, please say it again."

"No," Harry said, raising his voice, "I,"

"I know you've forgotten, Potter, and that means this crucible garbage is useless. Disappear without a trace. ”

Harry's potion vanished in an instant. He stood stupidly beside an empty cauldron.
