Zhang Ziyu has just come out of the monster ranch and is going to go to the kitchen to ask the house-elves to make some food.

As soon as he walked out of the corridor, he heard a cold voice behind him.

"Professor Zhang, wait."

Zhang Ziyu turned his head to look and found that it was Snape, it was okay, this guy's voice was so cold, but it didn't have any malice.

"Is there anything going on, Professor Snape?"

Snape nodded, looked at the students around him, his face was slightly gloomy, and said seriously, "I want to talk to you about Lamus Lupin, I don't think he's suitable to stay at Hogwarts."

Lupin and Snape had a big feud, Sirius Black wanted to play tricks on Snape, so he deliberately exposed his tracks on the night of the full moon so that Snape could follow, strayed into the screaming shack, and was almost killed by Remus, who turned into a werewolf.

Well, although it's all a good thing done by the paranoid cub of Sirius.

But there is no doubt that Lupin, the great wrongdoer, is responsible for the black cauldron, so that Snape not only knows Lupin's identity, but is also wary of his danger.

"Do you want to tell him about his werewolf status, that's just a minor issue."

"Minor questions?"

Snaprap's voice became more serious, "Professor Zhang, that's a werewolf, I can't let something so dangerous appear at Hogwarts and put my students in danger."

"Isn't it very easy to pour the enhanced sleeping potion when the moon is full, and then lock it up in a secret room?"

Snape was skeptical of this, and immediately retorted, "No way, life and death water and tranquilizers don't work against werewolves."

"Coincidentally, the enhanced version I refined, the kind that can turn over the fire dragon, do you want to see it?"

Snape was stunned for a moment, Zhang Ziyu's rhetorical question happened to touch his domain - potions, if it weren't for Lupin's matter, he should have come to discuss the potions with Zhang Ziyu today.

Between Lupin being a werewolf and a magic potion, Snape stepped back and said, "I'm going to see the potions first."

"Let's go, go to your office."

The two of them came to Snape's office together, the office was not large, but there were many potions and materials, and it was definitely one of the richest rooms in the whole of Hogwarts.

"Look at it, just take a look at the effect, if it doesn't work, the full moon will have to use physical means to give Lupin a rest."

"I suggest using physical means directly."

Snape's face was still cold, but he was clearly interested in physically stunning Lupin.

Zhang Ziyu took out the potion and handed it to Snape, who took the potion, uncorked the bottle, and sniffed it lightly.

"The improvement based on the water of life and death, the magic power is so rich, and there are different potion materials.......

Snape looked up at Zhang Ziyu, his eyes full of praise from his peers, and said, "It's a very powerful potion, and it does have a sleeping and calming effect."

"That...... Professor Snape, all of your new potions are so straightforward to smell and what if they're poison?"

Zhang Ziyu asked curiously, and Snape's face suddenly darkened: "Boring question, I want to try the effect."

Snape couldn't say that he had been so curious that he had forgotten his normal protective measures.

Snape cast the spell, and suddenly a cage appeared in front of him, containing a Motra rat, struggling in panic.

He didn't have any mood swings from the panic of the Motra Rat, if it weren't for the fact that some materials were needed to refine the potion, the Motra Rat would have died long ago.

He carefully poured out a drop of the potion, then turned his head to look at Zhang Ziyu.

"Can I dilute it with water?"

He wasn't refining the potion, and he wasn't sure if it could be diluted with water, so he asked cautiously.

"Yes."

After getting Zhang Ziyu's nod, Snape soon added a large amount of water and began to dilute it, and a drop of blue potion liquid quickly turned the entire inside of the container into a blue liquid.

Snape expertly took out a drop and poured it into the mouth of the Motra Rat, and it wasn't long before the Motra Rat began to sway before falling to the ground.

"Shadowless!"

Snape used the most convenient way to verify the effect of the entire sleeping potion, and a hole appeared on the body of the Motra rat in an instant, and blood flowed out, but the Motra rat's body only moved slightly, but it still did not wake up.

"Not bad"

Seeing this effect, Snape was already very sure of this potion in his heart, the Motra rat is not an ordinary animal, it is a magical creature with magical power, but after diluting it hundreds of times, it can still turn over the Motra rat, which is equivalent to a small bottle of life and death water, and there must be no problem with the original version.

"Let him drink a whole bottle when the moon is full, I don't want to catch a werewolf in the middle of the night."

Snape handed the potion back to Zhang Ziyu, his face still cold, but he agreed with it.

No, this is just for you as a gift."

Coming out of Snape's office, Zhang Ziyu also carried several books on potions in his hand, which were all Snape's return gifts.

Snape didn't expect Zhang Ziyu to give gifts, and he was still a particular person, so naturally he also had a return gift.

I have to say that Snape, the old boy, has still studied werewolves, because Zhang Ziyu saw a research material on how to poison werewolves and restrain wolf venom.

Oh, watch out for the old man.

"Boss, you're finally here."

Lupin had been waiting for him for a long time, and Lupin's face was a little pale and he looked a little uncomfortable.

To be precise, he's been pale for a few days, and it's almost full.

"The course is arranged, the student registration is almost done, and the class starts next Wednesday."

Zhang Ziyu nodded: "Good job, I'll ask Dumbledore to give you a teaching assistant bonus."

Lupin rolled his eyes when he heard that this pie was drawn, he had already recognized that his boss was a fish monster, and he was familiar with painting pies.

"Boss, I'm going to take a leave of absence, it's almost full moon, and I feel very wrong."

Zhang Ziyu also knew this, nodded and said, "Okay, let's go to the box world, and then sleep well for a few days, it's not a big problem."

Lu Ping also knew about Zhang Ziyu's arrangement, and this time he was not worried about what would happen after he transformed, because the existence of the box world could completely restrict him.

Zhang Ziyu asked the Patronus to inform Dumbledore, and then entered the box world with Lupin, "intimately" prepared a stone house for Lupin with Transfiguration, and then handed the sleeping potion to Lupin.

Lupin drank it all, didn't say a word, and fell straight into a deep sleep, and the effect was outstanding.

Zhang Ziyu lifted him to the bed, and then went out, the moon was full in the past two days, just to observe the changes in Lupin.

Zhang Ziyu came to the place where the werewolf wizards were imprisoned, and the wizards were already emaciated and imprisoned in the cage.

"My lord, please let me go."

As soon as he got closer, the wizard began to beg for mercy, not at all as unruly as he had been.

Looking closely, they all looked haggard, pale, and looked like they had been hollowed out.

It's not that Zhang Ziyu doesn't give them food, that is, a small experiment is a loss of things.

"It's impossible to put it down, cooperate well, and if a cure for werewolves is developed, the wizarding world will remember your name." By the way, what's your name?"

"Williams Vickers"

Williams looked desperate, and only asked the name now, can this big pie be believed?

"My lord, I am willing to be a cow and a horse for my lord, and become a vassal of my lord, and I beg my lord to spare me."

"Really?"

"It's true!"

"Alright, Williams, give me another tube of your blood."
