Old Deng wanted to know what made the Knicks ask him for help in his heart, and he couldn't help but think about the Knicks.

Tifa was at a loss for what to do, bowed his head and said, "I know it's wrong, and I won't do it again." Her words interrupted Knicks' thinking and also interrupted Deng's movements.

"It's okay, kid, it's in our nature to be playful, can you show me your toys? I want a small one. Lao Deng comforted.

Tifa handed a firework she liked very much to Lao Deng, her eyes were full of reluctance, and she asked Lao Deng: "Principal, I gave you my favorite, can you not call your mother?" ”

"Thank you, I won't call your mother. But I want to see how it works. Old Deng winked at Tifa.

Tifa smiled, trying to light the fireworks that made the biggest move.

Afraid that something would go wrong with her, the Knicks snatched it and lit it.

The fireworks quickly exploded into the sky, a beautiful picture appeared in the air, and the explosion resounded through Hogwarts, and both professors and students looked up at the fireworks in the sky.

The Weasley twins were very excited, it was the fireworks they made, this appearance was very good, the beautiful fireworks and the scenery at dusk were the best publicity.

Professor McGonagall hurried to the scene of the incident, followed by a large group of young wizards, who were very excited.

The first to arrive was Filch, who used the Assassin's lightness and agility to make her way, and when she saw Nicks, she exclaimed, "What are you doing?" Want to ruin Hogwarts? It's a good thing the headmaster stopped you, but you're in danger and you're going to be expelled. ”

"We got permission from the principal." Knicks said softly, making Filch angry.

Lao Deng said at the right time: "Filch, don't be impatient, we are experimenting with toys, but the sound is a little loud." He turned to the Knicks and said, "Maybe you should tell the makers to reduce the power, otherwise it's not suitable for school, but I have to say it's beautiful, unbelievably beautiful." ”

Professor McGonagall arrived, and when she saw Nyx and Tifa, she turned ugly and asked Dumbledore, "What did they do?" ”

Dumbledore reassured, "Don't worry, Minerva, we did it together. He shook the fireworks that Tifa had given him and continued, "Take the students back, dinner is about to begin." ”

At dinner, the little wizards were excited. Harry and Ron did something big at the beginning of the school year, and now the Knicks and Tifa are doing it again. It's been a lively semester.

George and Fred sat on either side of Tifa.

Fred was the first to speak, "Tifa Lestrange, we heard you did it. ”

George: "Just arrived at Hogwarts and provoked the professor." ”

Fred: "We admire you. ”

George: "You're a good fit for Gryffindor. ”

Tifa was embarrassed, bowed her head and ate in a muffled voice, ignoring the twins.

Knicks said: "George, Fred, someone has a bad review of your fireworks, he said that your fireworks are too powerful, and the school had better get some less powerful." ”

George: "It must be Snape?" ”

Fred: "Or maybe Filch?" ”

"It's Headmaster Dumbledore." Tifa didn't look at the twins as she spoke. She moved as if she didn't say it.

Hermione exclaimed, "You guys were caught by the Headmaster? ”

Knicks corrected, "Actually, it was they who got caught by the principal, and I happened to see it." ”

The crowd looked at Tifa in amazement, but as if it had nothing to do with her, she ate as if no one was around. All eyes turned to the Knicks.

"When I found out, Tifa and Luna were debating whether to put more power or less power. Headmaster Dumbledore appeared behind us, and he suggested putting the less powerful ones. ”

After the Knicks said this, Dumbledore thought that Tifa's choice was less powerful, but in fact, Tifa's choice of fireworks was the most powerful one, no wonder Old Deng said that it was too powerful.

The twins asked, "And then?" ”

"And then the fireworks went off." Nick Dow. "By the way, Tifa also gave old Deng one, you have to be careful, maybe Headmaster Dumbledore will look for you."

The twins looked at each other and said to Tifa, "Thank you so much, little Tifa, Dumbledore has taken a fancy to our product." ”

Hermione: "You're so optimistic, Dumbledore might ban fireworks." ”

Knicks shook his head: "No, if it is forbidden, it will not let me tell George and Fred to reduce the power." ”

Ginny on one side thought she had fireworks too, maybe she could share them with Harry. The thought of setting off fireworks with Harry made her blush.

Principal's Office.

Dumbledore handed Snape the powerful recovery potion made by Nicks and asked, "What effect does it have?" ”

Snape sniffed and said, "A powerful restorative, the formula has changed, and the effect has been enhanced." ”

"Severus, can you make one out of these?" Deng Sr. took out the mandrake scraps, which the Knicks had left in the hollow of the tree.

Snape examined it and replied, "Mandrake, it's not very well developed and not suitable for making potions. ”

Thinking about it, Deng decided to tell Snape the truth, saying, "Nick Lestrange used it to make that powerful restorative potion. ”

Snape pondered, and after a while, said, "Nice idea, to make up for the mandrake with other materials." ”

Lao Deng emphasized: "Severus, he spent an afternoon making the potion, and he improved it as he did it. ”

Snape was silent, normal people need to experiment to improve a potion formula, and succeed by chance in the midst of failure.

There are lucky people who can succeed at the first time. But the Knicks were not lucky to succeed, and the materials affected each other, and the rest of the mandrake was neutralized.

It's not all put in a pot, just add water and boil it, and it's a lucky success. To make a potion, you need to process the ingredients one by one, and the amount of time invested and the number of times you stir it will have an impact on the potion.

"What do you want me to do? Nick Lestrange was gifted in Potions. Snape asked.

"I hope you can pay more attention to him and don't let him go down an irreparable path." Lao Deng couldn't figure out the Knicks' distress feelings, so he could only wait for a turnaround.

"I will." Snape left.

For the rest of the day, Tifa was quiet, spending her days in the library with Nyx. The heavy pressure of studying left her with no energy to do things.

Nicks latched on a Mandela leaf on a full moon night. He became quieter, did not talk much, and rarely ate, only drinking porridge. Tifa was worried, and Hermione knew that the Knicks had started the Animagus ritual, and she comforted Tifa, telling her that she would be fine in a month.

Ginny eats and goes to class with Tifa every day, and behaves normally, but before she knows it, her face has deteriorated.
