Hogwarts: I have the Kamui Sharingan

Under the strange gazes of everyone, Zhang Xun nodded calmly. Even if Professor Snape had many shortcomings, he would not really persecute any young wizard, and Zhang Xun still recognized Professor Snape's teaching ability.

He stood up and said goodbye to Draco, who could only nod sadly. He originally thought that since Zhang Xun and he were in the same college and in the same dormitory, the two of them could play together every day. But after three days of classes, basically Zhang Xun can only be seen during class and before going to bed at night. At other times, Zhang Xun is either in the library or is called to talk by professors.

He rolled his eyes. He had nothing to do anyway, so he might as well go play with Harry.

On the other side, Zhang Xun followed Professor Snape to his office. The shelves in the office were filled with various glass jars, in which some animal fluids were soaked in colorless, light green or light red liquid. Organs that make you feel inexplicably horrified when you accidentally see them.

Then, Professor Snape pulled out an old hardwood chair from behind his desk. The black paint on it had been rubbed off due to age.Professor Snape looked at Zhang Xun looking around, with an ugly smile on his lips, and said sarcastically, "What? Is there anything you want to comment on, Mr. Dark Wizard?"

Seeing that there was only one chair in Professor Snape's office, Zhang Xun shrugged helplessly, "Oh, sorry Dean, I just thought we might talk for a long time, so maybe I would be more comfortable if there was a chair."

Professor Snape's face darkened, and his words seemed to be squeezed out from between his teeth, "Do you need me to give up my chair to you?"

Zhang Xun immediately bowed and apologized. He didn't even dare to say it, but he couldn't show any apology on his face.Professor Snape snorted coldly. He took out a piece of parchment from the drawer of his desk and said coldly, "I heard from other professors that Slytherin House has a genius this year, so let me see Has your clever brain developed any talent for potions?"

"The potion on this parchment, if you master it within an hour and brew it perfectly in one go, then I allow you to come to my office every night and do some basic work for me."

Professor Snape's idea surprised and expected Zhang Xun. He expected that Professor Snape would restrict his actions and would definitely find an excuse to tie him to his side to prevent him from destroying Professor Dumbledore's plan. , Surprisingly, he didn't expect Snape to choose such a method.

Zhang Xun, who has amazing powers of observation, can extract most of the techniques for refining the potion even just by watching others brew it, let alone a personal demonstration by a potion master.

But this alone is not enough to satisfy Zhang Xun's appetite, "Sorry, Dean, I don't think I can spend all my time on potions. Secondly, just helping you is not enough. I need you to teach me more knowledge." ."

Zhang Xun's greedy and ignorant words made Professor Snape's lifeless face lively for the first time. His anger could be felt even by Zhang Xun who was standing far away.

"Stupid and arrogant Eastern boy, perhaps the praise of others these days has made you forget your respect for magic! This is Hogwarts, not your Chinese Dragon and Tiger Mountain!"

Obviously, Professor Snape was still brooding over the failure that day, but Zhang Xun was like a steadfast pine tree, motionless despite Professor Snape's rage.

He bowed slightly and said, "Please forgive my ignorance and arrogance, but Professor Snape, why don't you trust me and give me one chance at a time, or are you afraid?"

Of course, Professor Snape would not be fooled by this simple provoking method. The anger on his face suddenly disappeared, and then he took out another piece of parchment from the drawer, and then said darkly, "Okay, in that case , I will give our Mr. Dark Wizard a chance."

He threw the parchment into Zhang Xun's arms, "The assessment conditions remain unchanged, but instead of the content on this parchment, and as long as you can refine the perfect potion, I not only agree with you to change the time to every Show up at my office on time on Wednesday, and teach you how to make an additional potion every week."

He raised his chin arrogantly, so that Zhang Xun, who was still a little short, could only see his tall aquiline nose, "Please, our Master Tianshi, if you can't refine the magic potion that satisfies me, you can You will face a month of confinement, and believe me, no one will dare to fish you out of my confinement room."

Zhang Xun nodded silently, then picked up the parchment in his arms, unfolded it and looked up at Professor Snape, "Then can I use your potion equipment?"

I thought Zhang Xun would regret it and was about to ridicule Professor Snape, who twitched his face. He nodded angrily, okay, arrogant boy, you will pay the price for your arrogance!

After Zhang Xun obtained Professor Snape's permission, he had already begun to immerse himself in the contents of the parchment. The problem Professor Snape gave him was the invisibility potion.

The materials are:

Five-color flower nectar, invisible animal excrement, a horned bat, a dried smokeless fruit, and a pile of black sour fruit seeds.

Proceed as follows:

[-]. Use a wooden knife to take out the nectar of the five-color flower and mix it with the excrement of invisible animals to combine the smell of the excrement.

10. Cut off the horn of the long-horned bat with a silver knife. Use only the tip one-third of the horn, grind it into powder, add it to the crucible and heat the mixture with water for [-] minutes.

5. Use the wand to stir the liquid counterclockwise four times until the liquid boils. The stirring speed during the period needs to be even, and then wait for [-] minutes.

……

(Note: The above is made up by the author. Anyway, the refining process of the invisibility potion is not mentioned in the original work. Please be careful when imitating it.)

Below are some key points for material processing that Professor Snape added, densely written on a piece of parchment.

Zhang Xun patiently read it word for word, and then he was ready to start, and said silently in his heart: System, I have designated to increase the success rate of refining the invisible potion.

[Hey, the concept of refining the designated potion with a monthly increase has been successfully used, and it is being corrected for you]

There was a confident smile on Zhang Xun's lips, which made Professor Snape, who was watching coldly, look extremely mocking. He believed that even if there were his notes on the parchment, it was absolutely impossible for Zhang Xun to directly use the potion in one go. Perfectly refined.

But as Zhang Xun handled the potion, Professor Snape's expression became more and more serious, and Zhang Xun copied the steps he wrote on the parchment exactly!

You must know that he wrote four or five methods on parchment just about the stirring methods of invisible beast excrement in different states, not to mention other materials. There are more than 30 processing techniques in total. Zhang Xun actually did it. Can you remember it clearly in less than 10 minutes?

This is naturally not a problem for Zhang Xun, who has the ability to correct the system and strong observation. In less than an hour, Zhang Xun has already put the last cooled potion into the potion bottle. In terms of quality, it is only slightly inferior to It's just a truly perfect invisibility potion.

Although he really wanted to find fault, Professor Snape could use this to attack him, but he really couldn't ignore his appreciation for Zhang Xun's potion talent. He stared blankly at the potion refined by Zhang Xun in his hand, and finally his lips remained motionless and his face remained expressionless. He said softly, "Get out."

Zhang Xun was stunned. He really didn't expect that Professor Snape would give such an answer. He thought that Professor Snape might force him into confinement because the potion was not of perfect quality, but he never expected that Professor Snape would give him such a reply. Professor Nepp would just cheat.

He moved his lips, but still didn't say a word. He nodded silently and left.Just as he opened the door, Professor Snape's deep voice came from the office, "Every Wednesday, Friday, and Sunday afternoon after dinner, come and wait for me outside my office for extra potions teaching. Set for Sunday.”

Zhang Xun looked back in surprise at Professor Snape, who was still facing away from him. He bowed excitedly and thanked, "I understand, Dean. Thank you for your teaching and generosity."

"Go away, don't forget to bring your stupid brain and your damn chair with you next time!"
