For a month, the Knicks went to Professor McGonagall's office every night to be locked up.

Under Professor McGonagall's guidance, he was able to use Transfiguration correctly, and his mana control was greatly enhanced.

Under normal conditions, it can accurately hit the target.

Magic also doesn't make plants grow or die, that's the power of the medicine man, controlling plants, not magical nature, completely ineffective against living animals.

This reminded the Knicks of the fact that the spell hit Lowe but didn't work.

Professor McGonagall experimented with Nicks, who could control a seed to grow into a tree, but the magic would die if it was depleted and not planted in the soil.

The confinement in Snape's church was even worse, and Snape treated him as a small worker, taught him to handle medicinal herbs, and then threw him a large number of medicinal herbs, which he called "deepening memory".

Nyx found quite a few substitutes when dealing with potions, most of which were Sequence 8 and Sequence 7 potions.

He put them together and asked the Weasley brothers to help them find them.

So far, the Weasley brothers have been paid 30 gold Galleons.

Let Nick get together the potion materials for Midnight Poet and Lucky.

It's a pity that the pre-potion materials haven't been found yet.

Leaving Snape's office, Filch was seen in the hallway cleaning up the big dung bomb.

Filch's hard work made the Knicks feel comfortable and said, "Haven't you figured it out yet? I can give you the ability to cast spells. ”

Filch ignored Knicks' words, he looked at Knicks and said, "It's curfew soon, don't let me catch you wandering around." ”

Nicks: "Think about it, you can cast spells, the stains on the ground disappear with a wave of your hand, and it's not a problem to catch the Weasley brothers." ”

Filch stared at the Knicks with only menace in his eyes.

Nicks' persuasion failed again, and before turning to leave, he said again, "Maybe you can ask Professor Snape or Headmaster Dumbledore if my potions really work like this." ”

Back in the common room, the Knicks are caught by the Weasley brothers, who have been waiting for a long time.

George: "Nyx, do you really have a potion for Squibs to cast spells?" ”

Fred: "It's not like you're trying to trick Filch into drinking something." ”

George: "We can help you. ”

Fred: "Filch doesn't know potions, just add them to the water." ”

Nix: "I'm not sure for sure, but it's likely that the potion will give Filch the ability to cast spells, or at least some special abilities, so you can't give it to him, and you have to pay for the materials." ”

George: "How many gold gallons do you want?" ”

Knicks: "It's not a Kim Galleon problem. ”

Fred: "That's the problem. ”

Knicks: "Of course he was asked to take out all his savings over the years, and the things he confiscated. ”

The Weasley brothers looked at each other, according to Nix, the potion really restored Filch's ability to cast spells, not a prank.

Nicks: "How did you know I was going to give Filch a potion?" ”

Fred: "We were just on the side. ”

The Knicks thought to themselves that he would tell Filch tomorrow that he would go berserk.

George: "If you do have this potion, I mean if, we can sell it for you, for a small cut, trust us, you can get more gold Galleons." ”

Nix: "You're sure you're going to sell it, I don't know what the aftermath of the potion is." ”

George and Fred looked at each other again, and Nicks meant that the potions were still experimental. Something went wrong, and the Knicks weren't responsible.

At Hogwarts, if something really goes wrong, Professor Snape solves it, Professor Snape can't solve it, and Headmaster Dumbledore takes care of it.

They gave up selling potions, and if something went wrong outside, they were going to lose money. The two felt a little pity for Filch, not only becoming a test subject for the Knicks, but also paying the Knicks.

The next evening, the Knicks were locked up in Snape's office.

Snape: "I heard you have a potion to help Filch cast spells. ”

Knicks: "yes. ”

Snape: "Can you configure it now?" ”

Nix: "You make the materials?" ”

Snape: "Yes. ”

Nicks: "You know the recipe, give me some money, and you will make a lot of money selling this potion in the future, and I won't lose much." ”

Snape: "I'm not going to sell it." ”

Nix: "Huh. ”

Snape bruised. "How much do you want?"

Knicks: "I don't need money, and I'm not short of money." ”

Snape suppressed his anger: "And what do you want?" ”

Nix: "Give me some herbs." ”

Snape: "Okay. ”

Nicks rummaged through Snape's private pharmacy, and there were a lot of materials here, including quite a few contraband, presumably obtained by Snape in the Forbidden Forest.

In fact, he can quickly select some materials to make potions, and it is rare to see rare materials, so it is a pity not to look for substitutes.

In the process of identifying potions, he discovered that the Guardian Potions had all been replaced, and that was the Dusk Giant's Path Sequence 5, the highest sequence that could be made right now.

Configure the potion and warn: "This is a high-level potion and cannot be drunk directly." ”

Snape: Still guarding me? "Why?"

Nicks: "If you don't have a pre-potion to drink it, you can go crazy, and if you don't go crazy, you will gain some special abilities." ”

Snape: "You're going to give Filch this potion?" ”

Knicks: "I knew he was asking, don't worry, I won't give him such a high-level one, I don't have those materials, I will only give him the lowest-level one."

By the way, if you're looking for someone to experiment with potions, I'd recommend going to Hagrid, he's a good fit. ”

Snape: "That's all for today's lesson, you can go." ”

Knicks: You can't kill donkeys as fast as you do.

Snape finds Old Deng with the potion. and told all the Nix's words to Old Deng.

Snape muttered, "Why did he let us give Hagrid a drink?" ”

Lao Deng said jokingly: "Maybe it's because he's big, and in the eyes of children, big is powerful." ”

Snape: "Trolls are bigger. ”

The two looked at each other, and there were really trolls in the castle.

Snape subdued the troll in the Chamber of Secrets and poured the potion into the troll's mouth, and after a while the troll went berserk.

Break free from Snape's suppression and try to attack the two. The trolls seemed to have new abilities, and Snape's Blade was unable to cut through the troll's skin.

He stepped up his efforts and finally slew the troll, obtaining something the size of a fist, like a heart, filled with holes and shimmering with the light of the morning light.

The next day, Professor Quirrell received an order from Deng that he needed to prepare another troll, and the previous one died.
