Because of the tragedy of the Horcrux missing on the first day of school, Li Yang looked in good spirits in the next two months, and Harry and the others thought that he had diarrhea in the first few days of school, and they gave sympathy and comfort.

Ron also lent the mouse to Li Yang for a while to play, but when Li Yang asked to buy it again, he was snatched back by Ron's calf.

The beginning was not good, and the dog was still someone else's.

Thinking of the three-headed dog in the forbidden area and the level behind, Li Yang couldn't help but feel a headache, and even the praise from Mrs. Hodge and Professor McGonagall in class couldn't comfort him at all.

Maybe it's bad luck.

"Longbottom!" Snape snarled and strode down from the podium to Neville's desk, his black robes whipping up a gust of wind.

"Teach...... Professor. Neville shrunk his head.

Snape's wand was like a whip, pointing at the steaming cauldron on Neville's desk, "Tell me, what are you doing?" ”

"Scabies Treatment Potions."

"You're a scabies treatment potion?" Snape said in questioning tones.

The whole class was silent.

Neville asked weakly, "Yes...... Is there something wrong? ”

Snape's face sank, "I heard that your grandmother sent you a memory ball, and I think she should send you another brain." ”

As soon as the words fell, the crucible on Neville's desk bubbled, and then cracked, and drops of green juice splashed in all directions, and Neville, who was close, was splashed on the spot, and patches of red and swollen scabies immediately surfaced on the skin that was splashed.

Neville screamed in pain.

There was also some liquid, splashing towards Harry, Hermione, Ron, Seamus, and the others who were closer to Neville.

With a flick of his wand, Snape was gone, including the cauldron.

Then the wand pointed at the podium, and a bottle of finished potion that had been used for demonstration flew over from the podium, reached out to catch it, uncorked it, and sprinkled the potion drop by drop on Neville's red and swollen area.

After a while, the redness and swelling disappeared, and the scabies were gone.

"Thank you, Professor, thank you......" Neville thanked Snape, tears in his eyes from the pain.

"Bang!" Snape didn't appreciate it, and with a calm face, he slapped the small half-bottle of potion that was still in his hand on Neville's desk.

"This is the scabies treatment potion."

"Know...... Got it. Neville lowered his head, not daring to look directly at Snape, his voice choking.

"Potter." Snape suddenly turned his head to look at Harry.

“…… Professor. Harry didn't expect Snape to pick up on him, and he replied with some sluggishness.

"Why did Neville's potion go wrong?" Snape asked.

Harry replied, "It's because he didn't put the pot on the pan and put in the porcupine thorns." ”

Hermione next to her nodded, she thought the same thing.

The answer was obviously correct, for instead of saying no, Snape said, "If you know, why don't you alert Neville?" ”

That's what I didn't know until now.

Before Harry could say this, Snape said directly, "Because of your indifference that led to this mistake, Gryffindor deducted five points." ”

Ha?

Harry was stunned.

He didn't expect to be able to deduct points like this.

As he was about to argue, Snape flicked his robe and turned away from the table.

"Harry's group of people will be punished for copying the formula of the scabies treatment potion thirty times, and when they will make a bottle of finished potion they will be allowed to leave, and the rest of them will leave the class."

Li Yang, who had been silent on the very edge, twitched the corners of his mouth, and finally had a reaction:

He teamed up with Harry......

Ron shouted at Snape on the podium, "Professor, we're going to have a Halloween dinner in a moment." ”

Snape gathered up his tools on the podium, replied without looking up, "The Halloween dinner can be held without the five of you", and then left with the rest of the students who had left class.

"My Halloween dinner." Ron cried out feebly.

"You know how to eat, I didn't make a mistake, but I will also be punished for copying, what did I say." Hermione huffed.

"I think Snape is deliberately finding fault with us." Harry was not angry.

"I'm sorry." Neville apologized, then lowered his head and took out a pen and paper, admitting punishment.

Li Yang then sat down as well, Guan Newei asked for some paper, and wrote it in a hurry.

Of the five, two took the lead, and even if the three of Harry were not convinced, they had to pinch their noses and admit it.

For a moment, the class was completely silent, except for the rustle of quills.

Thirty times is good to say, after all, it's just a simple potion formula, and it's not a long article, but the bottle of finished potion that is required to be dispensed is a bit troublesome, not only to boil it step by step, but also to guarantee a one-time success, if you are unlucky, it is very likely that it will not be possible to configure it successfully this night.

The luck of the five was not bad.

And the first one to finish it was not Hermione, but Neville.

"Well, I'll have another bottle." Neville finished writing and dispensing the medicine, but looking at the four people who were implicated by him, they were still buried in the cauldron and writing hard, and he was really embarrassed to leave.

Hermione didn't speak, as if stimulated to dispense the medicine harder.

"Okay." Ron smiled unceremoniously.

Soon, Hermione was also ready for the medicine.

In this way, Harry became the last.

Don't count Li Yang's words.

"I'm fine too." Harry let out a sigh of relief.

Now only Li Yang is left.

"What's the matter with you?" The four of Harry all looked at Li Yang in disbelief.

You must know that Li Yang's academic performance this month has been very good, especially in the flying class and Transfiguration class, and he also performed well in other classes, although there are no outstanding results in the Potions class, but he has never made a mistake, what happened this time?

"Bad luck."

Li Yang shrugged his shoulders and said helplessly: "You guys go first, the dinner shouldn't be over yet, I'll do it myself for a while." ”

"What's so embarrassing about that?"

"yes, let's go together."

"Come on, I'll do it for you."

"Harry, you're cheating, it's not right."

Li Yang waved his hand to stop the four of them, "This is not a sword mountain and a sea of fire, there is no need to live and die together, you go now, you can still catch up with the meal, it's late, I'm afraid you'll be hungry this night." ”

Li Yang didn't mention this stubble, but when he mentioned it, the four of Harry all felt hungry, and Ron's stomach screamed even more angrily.

"Go ahead, Hermione is right, if you really want to help me, you shouldn't help me cheat, you can help me pack some food, I don't want to go hungry tonight." Li Yang said with a smile.

"Okay then."

"Don't worry, I'll leave you a copy of everything that's delicious."

"Good luck."

"We'll come back to see you later."

The four of them didn't insist anymore, and after saying goodbye to Li Yang, they hurried to the restaurant.

Li Yang was the only one left in the classroom.

"I finally got a chance to be alone in Potions class, but I didn't expect it to be in this way." Li Yang shook his head, not knowing whether he was happy or bitter.

He didn't rush to dispense the medicine, but closed it first, and Harry and the four of them left in a hurry without closing the classroom door.

Then, Li Yang still didn't go to dispense medicine, but went to the podium and rummaged through the lectern.

Didn't find it.

"Where?" Li Yang muttered in his mouth, restoring all the things in the lectern and eliminating the traces he had rummaged through.

He looked to the rest of the room.

In the back corner of the teacher, there were a few empty tables and chairs that were not used, as well as a locker, which was mixed with some Potions class tools, very old ones, and I don't know how long they had been stored here, and finally it was here that Li Yang turned out a book:

Advanced Potion Preparation

The book was very worn, the pages were yellowed and dusty, and it had not been left for long, and the badly discolored cover could barely make out the words of Liberasius Polage.

Turning it over, there is a very eye-catching line on the first page:

This book belongs to the half-blood prince!

"I've finally found it." Li Yangle put the book away.

I've finally picked up a piece of equipment.

After removing the rummaging marks of the desk and locker, Li Yang returned to his desk and made it according to the recipe of the scabies treatment potion.

It was made in just one pass.

Li Yang bottled the potion, packed up his homework and dispensing tools, and left the classroom.
