HP: After binding to the strongest wizard development system

The lazy setting sun in the afternoon never visits the dark Spider End Alley. When Lucius stepped into this small, closed and dilapidated house, his gray eyes naturally showed a bit of disgust.

Lucius covered his mouth and nose with a handkerchief, as if breathing the air in the room for a second longer would make him feel extremely dirty: "Sev, I'm not telling you, you obviously have enough assets to buy a better house."

"If you have something to say, you can leave if you can't stand it." Professor Snape looked at him indifferently, not at all embarrassed by his friend's dislike. He never seemed to take it to heart.

Lucius took a deep breath and tried to calm down his tone. He will not forget the purpose of coming here: "Sev, I heard that you found a few werewolves for experiments some time ago? Let's talk about cooperation, about the wolfsbane potion you have."

"You will never suffer a loss by cooperating with our Malfoy family." Lucius' tone became proud again.

The soft and slender golden hair was carefully cared for every day. At this time, they were spread back because of Lucius's slight upward movement of his head. Even in the room with only dim candlelight, they had a strong presence.

Just like their owner, a nobleman who never lowers his head proudly.

Professor Snape looked completely different from him. The latter looked out of place in this room, but he was no different from the shabby sofa behind him, and seemed to fit in perfectly with the room.

"I'm afraid not." Professor Snape raised his eyes and calmly rejected his surprised friend, "The wolfsbane potion I experimented with was not developed by me, and I have no right to cooperate with you."

If it is just for Professor Snape's private research, or if a werewolf comes to visit, Professor Snape has the right to brew a small amount.

But once he cooperates with the Malfoy family, it means that Professor Snape has to hand over the formula of the improved version of Wolfsbane potion. He does not want to do such a huge profit-making thing.

Although he considers himself not a principled person, potions are special to him and are the only ones that can prove his worth. He didn't want to change his original intention on the potion for the sake of money.

"Come on, Sev, what's the harm in cooperating with me?" Lucius and Professor Snape looked at each other, trying to know if this was Professor Snape's refusal.

After looking at each other for a while, he felt that Professor Snape was not interested in money, so he smiled again: "Then, you can always tell me who developed it, right? I will go find him to cooperate."

"I bought it by accident. I can't find the person." Professor Snape simply replied, hiding Till's role in it without leaving any trace.

It's not time for Till to officially appear in the public eye.

Lucius asked without giving up: "Really can't find it?"

"Yes." Professor Snape nodded impatiently. After checking the time, he directly ordered the expulsion. He had no intention of saying anything to Lucius. "It's time for you to go back. Didn't you say that your child has been very noisy recently?" ?"

The implication is to ask Lucius to go back to see the child quickly, instead of spending time with him for a cooperation that is definitely impossible to achieve.

At the mention of children, Lucius' tight lips relaxed, and it seemed that his attention had indeed shifted. However, he still took a deep look at Professor Snape before turning around and leaving the place where he had been uncomfortable. room.

Before leaving, he left Professor Snape with a message: "In recent years, some people have begun to stop. I think you know which party is worth seeking refuge in."

"Is it worth trusting?" Professor Snape sat on the broken sofa with rusty springs and repeated it with a sneer. No one knew who the sarcasm in his eyes was directed at.

For him, there was never a question of whether it was worth it or not. At the beginning, he had a choice, but now he can only be arranged to move forward.

What does it mean to know or not to know?

"Knock, knock, knock." Several consecutive knocks came from the small window.

Professor Snape was very familiar with this voice, and subconsciously guessed that the old professor had asked his conspicuous phoenix to deliver the message again. Who knew that when he went over and took a look, he saw a familiar phoenix that he had not seen for several months. owl.

Hibby held the box in his beak. When he saw that Professor Snape was just standing and had no intention of opening the window, he came closer and knocked on the glass of the window again, blinking his big eyes in an urging manner.

Professor Snape looked at this stupid and stupid owl, but still chose to open the window and let it in. Hibby had been here before, although not many times, but he quickly found a suitable place and threw the box up.

The box collided with the wooden tabletop, making a dull sound, and the glass tube containing the Billywig worm also shook a few times and made a rustling sound.

Professor Snape frowned. He didn't know what Thiel had asked the stupid owl to bring. He quickly stepped forward to open the box and took a look. His frown deepened.

The Billywig bug is all blue. The wings on the sides of its head can be used to make laughter potions, and the sting at the bottom of its body is also a versatile potion material.

Till gave him such a large jar of Billywig worms... Professor Snape stared in thought for a while, and suddenly remembered that Till had asked him about the eating habits and breeding conditions of Billywig worms before.

This insect, native to Australia, often eats a short, light gray grass called grati.

Grati, a short gray grass that grows only in warm, dry climates with little rain, has nothing special about it except that it is loved by billywig bugs.

But it cannot be ignored that its name comes from the Latin Gratia, which means thanks.

Professor Snape held up such a large jar of Billywig worms in front of him and couldn't help but move the corners of his mouth. If Till was thanking him, thanking him for such a big jar would be too much.

"Oh..." Hibby waited quietly for a while, without waiting for Professor Snape's reaction, he called out, and then tapped his paw with his beak.

"Are you... your claws itchy?" Professor Snape tried his best to guess. For the sake of Hibby's master, he thought about finding a stone so that he could sharpen his claws.

"Oh!" Hibby yelled louder. This time he tried his best to lower his beak, but instead of tapping his paw, he scratched his beak with his paw.

This hint is much more obvious. Professor Snape knows that it is asking for food from him. It is also recognized in the wizarding world that a busy owl should be given some food as a reward, but...

Professor Snape smiled and seemed to be in a good mood. He picked up Hibby and threw the silly owl out of the window when he thought he was taking it to eat food.

If he doesn't give it, what can this owl do to him?

Throwing the owl, closing the window, and going upstairs, Professor Snape performed a series of actions in one go, which made Hibby so angry that he scratched the brick wall of the house several times, and then flew in the direction of his master in aggrieved manner.
