Last year, half of the students in the class participated in Silver's after-school cram school for the Black Magic Defense Arts. They had learned protective spells such as the iron armor spell. However, none of them had recited this spell without making a sound. It is conceivable that the following was a lot of cheating. Many students were chanting the spell in a low voice, but they just didn't amplify the sound.

However, in addition to the ordinary black magic defense tutoring class, Silver also has a higher fee (black) after-graduate class and the ultimate class. As expected, in ten minutes of class, Malfoy, Hermione and a Lavenclaw girl successfully cast a silent spell - Snape added 20 points to Slythering, while Hermione and the Lavenclaw girl's performance was ignored.

Harry and Ron were separated, Harry was arranged to compete with Silver by Snape, and Ron was assigned to a Hufflepuff boy. So far, they had not cast any successful silent spells, and Harry and Ron's faces were red, fearing that they could not resist the temptation and recited the spell softly.

"Potter, I have to say you're doing a bad job." Snape dragged his robe to Harry and Silver who were practicing. "From now on, you haven't even been able to cast a successful silent spell. Silver, let's attack."

"As for orders, Professor Snape." Silver waved his wand, and Harry was knocked to the ground by the spell before he could react.

Harry fell to the ground, not that he didn't have the strength to stand up, but he didn't want to face the ridicule of Snape and others.

But Snape obviously would not miss any chance to ridicule Harry.

"Oh, it's so bad. Potter." Snape's face smiled, and Malfoy laughed at Harry's clumsiness loudly. "I have to say. You really don't have any talent in this. Silver, go there first, let me come and practice Harry Potter."

The anger in Harry's heart ignited, and he climbed up from the ground, pulled out his wand to prepare to defend.

"Very good, Potter, so you look fighting spirit." Snape's tone still emphasized that Harry was angry.

It was soon after that. Snape suddenly turned his wand to Harry. Harry reacted instinctively, forgot all the silent spell, and shouted: "Armor protects you!"

His armored spell was too powerful, and Snape was hit and lost his balance and hit a table. The whole class turned his head and watched Snape struggle to gain a foothold, his face full of anger.

"Do you remember I told you, we are practicing the silent spell, Potter?"

"Remember," Harry said stiffly.

"Obviously you haven't understood the minimum classroom discipline yet, Porter." Snape said with a stern face.

"Do you want me to add a sir after remembering? Professor?" Harry said.

"Potter, confinement, Saturday night. In my office," said Snape. "I don't allow anyone to be rude to me, Potter...even if you are a savior."

———————————————————————————————————————————————————————————————————————————————————

"Harry, you shouldn't be so impulsive," said Ron. "Snape must not catch you."

"It's just a confinement. I'm not afraid at all." Harry said stubbornly.

During the break after lunch, Harry and Ron racked their brains to do Snape's homework. Before they could finish halfway, the bell for Potions class in the afternoon rang.

"Okay, Harry, Snape also has an advantage in teaching black magic defense. Now the potion teacher is not him. We can finally take the Potion class improvement class for Potion class," Ron comforted Harry.

"Yes." Harry said with a stern face, "Otherwise, if I am not satisfied with the three improvement courses, I will have to go back to Aunt Penny's house."

As they spoke, they rushed to the underground classroom along the familiar road, which had been dedicated to Snape for a long time.

They came to the corridor outside the classroom and saw only twelve or three students coming to improve. Obviously, Crabb and Gore's O.W.Ls scores did not meet the requirements, but four Slytherin students passed the exam, including Malfoy. There were four Ravenclaw students and one Hufflepuff student - of course, Silver and Hermione. Harry was a little unhappy. Silver's silent spell made him lose face, so he pretended not to see them say hello to him.

The door of the underground classroom suddenly opened, and before the Slughorn man showed up, the big belly had already emerged. The classmates walked into the classroom, his walrus beard trembling on his smiling mouth, and he looked particularly enthusiastic when he greeted Harry and Silver.

Unlike usual, the underground classroom was already filled with steam, filled with all kinds of strange smells. Harry and Ron walked past the big bubble cauldrons and smelled with interest. Four Slytherin students sat at a table, and four Ravenclaw students were the same. Silver and Hermione sat at a table, and no one dared to sit on the same table with them. Harry and Ron had to sit with the only Hufflepuff student Ernie McMillan, who was the chief of Hufflepuff and was quite acquainted with Harry and Ron. They picked a table closest to a golden cauldron, and the scent radiated from the cauldron.

"Okay, okay, okay, okay," said Slughorn. Looking through the hot steam, his big figure looked fluttering. "Students, please take out the balance, the medicine bag, and don't forget to take out your "Advanced Potion Making" textbook..."

"Sir?" Harry said with his hands raised.

"What's wrong, Harry?"

"I don't have books, I don't have a balance, I have nothing - too - because, we didn't expect to be able to go to the improvement class-"

"Ah, by the way, Professor McGonagall mentioned this...Don't worry, child, don't worry at all. You can use the raw materials in the storage cabinet first, and you can lend it to you today. There are some old textbooks here, you can use them first, and then you can write to Lihen Bookstore..."

Slughorn strode to a storage cabinet in the corner, fumbled for a while, took out two ragged books, Libashe Pollage's "Advanced Potion Making", written by Libashe Pollage, and handed them to Harry and Ron together with two sets of dark and faded balances.
