On Saturday afternoon, while on his way to the library, Jon returned the Cutting-Edge Transfiguration Guide to Mrs. Pince.

Back at the dining room for dinner, an owl appears and tosses a small box to Jon.

Jon took the box and pocketed it.

......

After dinner, he walked to Professor Snape's office.

In the past few years at Hogwarts, he has had to visit Snape's office almost every year due to some accidents, and Jon has even gotten used to it.

When he knocked lightly on the door, Snape's cold voice came from inside: "Please come in!"

Jon hurriedly walked in, "Professor Snape!"

At the same time, he glanced at the glass bottles of various colors on the shelves......

"You've arrived. Snape looked up, glared at him, and looked back at the cauldron, "The toad in the bucket, get rid of it!"

Jon then noticed that in the middle of his office, there was a large wooden barrel.

"Quack...... Wail...... Wail...... The sound kept coming from inside the barrel. ”

When I walked over, I saw that it was filled with dense toads, strange-looking toads, because they all had horns on their heads......

"Bohemian longhorned toads!" Snape coldly ordered, "Hart, take out their hearts and livers......"

As he spoke, Snape tossed over a silver knife.

"Yes, Professor!" Jon nodded, picked up the knife, and after a closer look, he finally put it back on the table.

Jon then took out the small box from his pocket that the owl had brought him for dinner.

As early as Tuesday, when he was notified of his stay at school, Jon wrote to Eric and asked him to buy two scalpels and a box of blades to send to himself.

After all, with his Bohemian long-horned toad, this creature has a very thick coat...... It's not easy to pierce with an ordinary knife.

Now, he had taken out a scalpel and loaded it with a blade.

There was no doubt that this was a tool that he had already mastered, and that it was obviously much more comfortable to use than an ordinary silver knife.

Easily grabbing a toad from the barrel with his left hand -

"Quack ......"

With only one scream, Jon easily plunged the scalpel into the toad's stomach and then lightly disemboweled.

It took more than ten seconds to discern the location of the heart and liver, and then put them in two glass bottles, and Jon tossed the dead toad into another empty barrel, and then took out another ......

At first, it was a little rusty, but after dissecting a dozen or so, the movements became proficient!

Snape looked up in amazement, watching Jon's skilful knife plunge into the toad's belly, as he easily removed the herbs he needed, and watched as he removed a somewhat dull scalpel blade and replaced it with a new one......

......

Only an hour and a half had passed, and the barrel, which had been empty before, was now full of toad corpses.

The other barrel, which had been full before, was empty.

"I think I'm done, Professor!" Jon picked up two glass bottles filled with horned toad liver and heart, respectively, and stood up.

"Put it on my shelf!" Snape said calmly, his eyes still fixed on the crucible in front of him.

Jon followed the initials on the herb shelves and placed them separately.

When he looked back, he heard Snape whisper, "You just ...... Show me the blades!"

Snape's voice was not as cold as before, but a little curious.

"Yes, Professor!" Jon quickly pulled another scalpel out of his pocket, as well as a new blade, and handed it to Snape.

Looking at Snape, it took several minutes to jerkily put the guard blade on the scalpel......

"Fragile and very easy to break...... But, it's sharp, too!" said Snape, staring at the scalpel in his hand as if to himself, and then lightly rubbed the blade on his finger.

With little effort, the blade easily cut a deep wound in his hand, and blood gushed out little by little.

"Reparo!" Snape lowered the scalpel as he pulled out his wand with his other hand and aimed it at his injured finger.

After almost a dozen seconds, the wound on his finger disappeared little by little......

Then, Snape put his wand on Jon's hands and whispered, "Scourgify!"

The blood stains left on his hands, as well as the internal organs of the toad between his fingernails, fell off little by little, and his hands became clean in an instant.

"Professor!" Jon preemptively said before Snape could speak, "I have two of these knives, if you don't mind, you can put this one in your hand here!"

Snape narrowed his eyes and didn't speak.

Jon quickly took out the blade box and poured out a dozen or so brand-new scalpel blades on Snape's desk.

Snape still didn't speak, he just waved his wand...... The scalpel and blade flew into his drawer.

......

"Now, do me another favor!" Snape said coldly, gesturing to the cauldron in front of him.

"Professor, what are you making here?" Jon asked tentatively.

"Wolf Poison Potion!" Snape said coldly, "A certain werewolf still needs my help to stay sane on a full moon night...... Hmph, if it weren't for Dumbledore's request......"

This wasn't the first time Jon had seen Snape's wolf poison potion, but the last time Snape had been to hint to him that there was a werewolf in the school, and this time, he showed almost all of the steps.

"For some of the more advanced potions......," Snape said slowly.

Jon quickly pricked up his ears.

"The difficulty in their formulation is not in the process or in the ......handling of the material," Snape continued, after a pause, "but in the last step." ”

"Even if it's the same potion, different wizards have to deal with it differently...... It depends on shamans to figure it out, and it needs a little inspiration, and it will never get it by reading books and seeking advice......"

"So I've always thought that potions require talent, and the kind of fools and fools I often encounter will never really be able to achieve real results in potions!" Snape sneered, "And this final step of processing, we call it a sequence of potions...... For any kind of high-grade potion, if you can't find a sequence that belongs to you, you'll never succeed in concocting it!"

Jon nodded thoughtfully.

At the same time, Snape's cauldron was emitting black smoke little by little......

Jon looked up and asked with some boldness, "Professor Snape...... Can I be locked up by you a few more times in the future?"

Snape gave him a cold glance and said sarcastically, "Whatever you want...... If you'd like to come here and do some dirty work as you did today!"

"Once a week!" he added, after a pause.
