The Potions Classroom is a large classroom located in the basement of Hogwarts Castle, which can accommodate no less than 20 students and various experimental equipment for the students, and the shelves on the walls are filled with various glass jars, which are soaked in a solution of animal specimens, which looks very frightening. There is a blackboard in the teacher with the materials needed to prepare potions and how to prepare them. There's also a magic material storage cabinet that stores all the ingredients that students might use to make potions.

As soon as he entered the classroom, Harper felt the temperature drop suddenly, very cold, and unconsciously rubbed his arms, ready to add a sweater to himself.

At this moment, Professor Snape opened the door through a small door on one side, and his black cloak shook off his handsome arc, and after standing in the center, he picked up the roster and began to take the roll call.

“Blaise Zabini、Cormac Mclaggen、Daphne Greengrass、Draco Malfoy... Ron Weasley... Vincent Crabbe" just as everyone wondered why Harper's name wasn't pronounced.

"Oh yes, Harper Potter, it's our new arrival—the famous one." Snape said with a slight sarcasm.

Draco listened to the professor's tone and felt that it was time for language education, as he used to call himself at home. After the roll call, Snape looked up at the class, his dark eyes without the slightest warmth, only indifference and emptiness, as if they were two dark tunnels.

"You've come here to learn the exact science and rigor of this potion." Snape spoke, almost a little louder than a whisper, but everyone could hear every word he said. Like Professor McGonagall, Professor Snape has the deterrent power to keep classrooms in order. "Since there is no stupid waving of a wand here, many of you will not believe that it is magic. I don't expect you to really grasp the beauty of the simmering cauldron that smoking, the fragrance wafting out, and you don't really understand the magic of the liquid that flows into people's veins, the thrilling and disorienting of the will...... I can teach you how to increase your prestige, brew glory, and even stop death—but one thing has to be, and that is that you are not the kind of fools and fools I often encounter. ”

Listening to Snape's words, Harper fell into deep thought. 'Potions can indeed have many effects, they can make people like a person, they can make people hate a person, they can make people obey their orders, they can make people change their mental age, etc., but death cannot really be prevented by any external force, if there is... How nice that would be! ’

As Harper pondered, he didn't notice Draco tugging at her sleeve, let alone hearing Snape call, until...

"Miss Potter! Miss Potter! Harper Potter！！！ As Snape's voice grew louder, Harper finally came to his senses.

"Hah! Professor Snape, you called me? ”

"Is there a second Harper Potter here? It seems that our Miss Savior is so good at Potions that you don't need me, the Potions teacher, to teach you? Snape was annoyed that she dared to wander in class, and that the person's last name was Potter, even though she had a face similar to Lily's, that didn't reduce her anger.

"What do I get if I add daffodil root powder to a wormwood infusion?"

"Sleeping pills, like?" Harper's mouth was full of words, pausing to give a possible answer.

"Looks like our Miss Savior seems to have a pre-study? Let's see if it's an accident. Snape thought to himself that James Potter didn't have this string for potions, and that his offspring should be just luck. If I asked you to go and find me a piece of dungstone, where would you find it? ”

"In the stomach of a sheep?" She muttered silently again for a moment before replying.

Draco and the others, who had answered correctly in a row, breathed a sigh of relief and prepared to watch the show. And Harper, who answered both questions correctly in a row, Snape didn't seem so angry anymore. At least she is occasionally arrogant, much like Potter, but she still has the good qualities to inherit from Lily. Snape seems to have forgotten that the Potter family, in addition to their flying talents, had ancestors who made their fortune with potions.

Snape, who calmed down, looked at the eyes around him watching the play, and just when everyone thought that he would continue to evaluate (obviously difficult) Harper, suddenly "Mr. Weasley, what is the difference between Aconitum scapulataus and Aconitum lupus?" ”

Ron Weasley, who was suddenly questioned, subconsciously stood up, then lowered his head and whispered, "I don't know." ”

"It seems that the brave Gryffindor doesn't understand the word preview, and Gryffindor deducts 5 points for this." Snape walked over to the blackboard, "Potter, you answer." ”

"Just by the name, you know that they all belong to one plant." Harper is glad to have benefited from the supervision and guidance of his friends in his previous life, and used music to endorse him, otherwise he would really be disgraced in the next life.

"Sit down, Slintlin plus 5 points, and while Miss Potter lives up to her reputation, Slintlin deducts 1 point for ignoring the teacher. Why don't you write it all down? Instantly, there was a rustle of quill pens and parchment in the classroom.

Potions class continued, but the situation for the Gryffindor students did not improve. Snape divides them into pairs and instructs them to mix a simple potion to cure boils. Snape dragged his long black cloak around the classroom, watching them call dried nettles and smash snakes' fangs, and almost all of the students were criticized, except for Draco and Harper, who were mostly handled by Draco and Harper. Just as he showed everyone how perfect Draco's method of steaming tentacled slugs was, a loud hissing sound suddenly came from the underground classroom with an acidic green smoke. Somehow, Nevill burned Seamus Finnigan's crucible into a crooked piece, and the potion in the cauldron spilled onto the stone floor, burning holes in the students' shoes. Within seconds, the class was on the stool, and Nevill was drenched in potion when the cauldron was knocked over, and his arms and legs were covered in red and swollen boils, and he screamed in pain.

"Idiot!" Snape roared, waving her wand to sweep away the potion that had been spilled on the ground. "I suppose you probably put the porcupine thorn in without opening the cauldron from the fire, did you?" He yelled at Nevill.

Nevill sobbed and cried, and boils popped up on his nose.

"Get him to the hospital up there." Snape snapped at Finnigan. He then circled around Weasle and Dean Thomas, who were right next to Nevill.

"Weasle, why didn't you tell him not to add porcupine thorns? Do you think he's going wrong and showing you? Gryffindor lost another point because of you. ”

Weasle was about to retort, but Thomas stopped him in time, and they couldn't deduct any more points.

An hour later, most of the Gryffindors were in a state of low spirits crawling up the steps out of the basement classroom. On the other hand, Slintlin was in high spirits, as if he had won the final victory.
