Coming to the underside of the beating willow, Nix warned: "Don't come without me, this tree is alive and will attack anything that comes close, I have a special way to keep it from moving." ”

"I see, brother. Are we studying here? Tifa worried.

"No, you wait." Nix could feel it, scattered branches around him. After turning around twice, he collected the remaining branches and said, "Let's go." ”

Entering the tree hole with Tifa, the little girl was very surprised and asked, "Is this the rabbit hole in Alice in Wonderland?" ”

"No, it's a secret passage." Nix replied. "Alice in Wonderland" is a story told when she was a child to lull Tifa to sleep, and most of the scenes in it can be found in the wizarding world.

Finding the mandrake, Nix breathed a sigh of relief, fortunately it was not poached by Old Deng. It seems that the elder Deng did not think that there was a need to return it to Professor Sprout. Without this mandrake, the Knicks' big plans would have been in vain.

Mandrake leaves are essential for the Animagus Transfiguration Ritual, and it itself can be used to make powerful recovery potions to restore the body in the event of a failed Animagus Ritual.

"Do you have your cauldron with you?" Nicks asked.

"With it." Tifa said.

"Take it out, and I'll teach you how to make a potion for boils." Nix said.

Tifa pulls out the cauldron, and Nicks gives her the same materials.

"Smashed the snake's fangs first...... Boiled the slugs...... Join the porcupine spur ......"

All the steps were perfect, but as the potion was about to take shape, Nicks noticed that Tifa was constantly muttering something to his mouth. Listening carefully, what she said was, "Must succeed, must succeed." ”

The Knicks didn't care, continuing to stare at the cauldron. He is extremely sensitive to magic due to its uncontrollable nature.

A wisp of magic slowly floated down the cauldron on Tifa's body, and then the whole pot began to smoke.

The Knicks covered their mouth and nose, but the smoke was getting thicker and thicker, and he couldn't see Tifa clearly. He cast a spell on the cauldron to remove the potion from it.

Without the potion, the smoke gradually cleared, and Tifa knew the consequences of smelling the smoke, so he hid in a corner for a long time.

"You've cast a spell on potions." Nicks affirmed.

"I didn't." Tifa retorted.

"I noticed that a wisp of magic power has entered the cauldron, if you want to brew potions, you must control your magic power not to mess around, otherwise next time it will not only smoke, but may also explode." Nick Dow.

Tifa asked, "Brother, is there any potion to help me control my magic power and not fall into the cauldron." ”

"No, if there were, I would have drunk it a long time ago, and don't forget that my Transfiguration is also difficult to control."

After saying that, in order to prove it, Nyx casts a spell on the crucible on the ground, trying to turn it into a pink pig. As a result, only half succeeded, and the other half was a crucible.

Looking at the pig's head facing up, the two front legs are slipping, and there is still a half-pig with a crucible underneath. Tifa giggled, and Nyx waved his hand, canceling the transformation, and said, "You need to control the mana, don't inadvertently cast spells on potions." ”

After Bontiva finds out the reason, Nyx uses Transfiguration to ripen the mandrake, plucking a few leaves to leave.

Tifa reached out to grab it, and asked curiously, "Brother, what is this?" ”

"Don't move, you'll know later, it's also dangerous, but useful." Nicks grabbed Tifa's hand.

The two of them slowly crawled out of the hole, and as soon as they came up, they saw Professor Snape with an ugly face.

"I don't think you want to burn the beating willows!" Snape said in a grim tone. He saw the smoke and thought the beating willow was on fire, and when he arrived, he found Knicks and Tifa climbing out of the tree hole.

"Of course, Professor, I didn't want to burn the human willows, just practice the potions you taught today." Nicks replied.

"Nick Lestrange, do you need to practice potions dispensing? And there was no Potions class in the second grade today. "Snape thinks the Knicks are lying.

Tifa, who had just come out, said weakly, "Professor, my brother is teaching me potions." ”

Snape's expression became indescribable when he heard Tifa's words, and after a while, he said, "You'd better find a place where people can be noticed, I don't want you to be poisoned and no one will find out, and when I find you, you'll already be a pile of dry bones." ”

"Okay Professor, next time we'll cook potions in the castle courtyard." Nix replied.

Snape grinds his teeth, this is to be angry with him, all he can do is to deduct points for the Knicks, but the deduction is meaningless to the Knicks. Forget about confinement, on the one hand, it's not worth it, and on the other hand, confinement is dangerous according to the level of potions of Knicks and Tifa.

Tifa was scared, and Snape put a lot of pressure on her, and asked in a low voice, "Brother, what should I do, won't I deduct points again." ”

The Knicks shook his head, thinking that it didn't matter if he deducted points, he was afraid of confinement.

"Hmph, you should be glad that there were no serious consequences, otherwise you would have been expelled." Snape frightened.

Tifa was frightened and whispered behind the Knicks, "What to do?" ”

"It's fine." Nick comforted her, and then said to Snape, "Rest assured, Professor, we are measured. ”

The Knicks really wanted to make the beating willow bend down and touch him, but he couldn't do it because he was incapacitated.

Tifa whispered, "Brother, come on." ”

Her voice was small, but both Knicks and Snape heard it, and their faces changed.

Snape didn't feel right to argue with the Knicks, which would undermine his majesty. The Knicks felt that Tifa's words were in trouble, and what could have been just a matter of verbal education was now going to rise to point deductions, or even confinement.

"You shouldn't have given her the ability to cast spells." Snape Road. He was the Knicks' guide, and he knew Tilfa was a Squib from the beginning. He was surprised to see Tifa at the opening party. But it's not surprising to think of Filch, and then to think of the Knicks.

Tifa behaved badly in Potions class, and Snape thought that maybe the wizards made by Potions were much worse than normal young wizards.

Coupled with the fact that Voldemort lurked in the school last year, and now he doesn't know where to hide, it is dangerous for a little girl to become a wizard.

In Snape's opinion, the Knicks could allow the elderly Filch to gain spell-casting abilities, and then it would be better to wait a few years for Voldemort's affairs to pass, and then let the little girl enter the wizarding world.

But Nix knew that Voldemort would eventually lose, and did not let Tifa participate in the battle with Voldemort, and he might be blamed for the rest of his life in the future, and in serious cases, he might not get along with him from old age.

"Her wish, as an elder brother, I have the ability to fulfill it."

Snape gave up his lecture and said to the two, "Now go back to the castle, and don't go near the beating willow again." ”

Nix breathed a sigh of relief, was not deducted points, and was not locked up, and quickly left with Timfa while Snape was pondering.
