The first Quidditch game of the school year ended with an unexpected ending.

Draco got a long joke. He kept imitating the dementor in front of Harry, performing Harry's embarrassing look on the broomstick.

Ron finally couldn't stand Draco's provocation, and in the potion class, he threw a huge, slippery crocodile heart on Draco's pale pointed face, causing him to stand unsteadily and throw him into Crab's arms. As a result, Snape deducted Gryffindor fifty points.

Harry seemed in a bad mood because he once again saw the big black dog that represented "unknown". Moreover, his 2,000 light wheel was blown to the side of the beating willow by the fierce beating willow, and he was beaten into more than a dozen pieces by the fierce beating willow.

The only thing that made him a little relieved was that the unknown seemed to have failed and failed to let him die. He thought with self-deprecatingly that the dog food he sent might be quite suitable for his unknown appetite.

In the divination class, Trelawney's eyes, which were so huge that she was placed in glasses, were filled with tears. She made Harry's face turn ashen.

Hermione's cheeks were so angry that she confronted Trelawney again, and then she threw the door and left after the bell rang.

In the Dark Magic Defense Class, Professor Lupin came back. Although he looked even more sick, there was a heavy shadow under his eyes. This made Draco and the others feel a little regretful.

Brian was still studying step by step. During this period, he continued to study potions every week at Snape's office, and began to learn how to cast spells without spells. Now he has successfully started.

His level of potions successfully reached the mastery level. According to Snape, he can now easily pass the O.W.L. exam. Some time ago, he easily made a series of potions including joy agents that he would only come into contact with in the sixth grade.

One night, Snape also specially taught him to configure Wolf Poison, a potion that is very complicated to configure and requires expensive medicinal materials, but Brian still cooked it successfully.

"Brian, tell me the effect of the wolf poison potion?" Snape's voice was deep and genuine as he looked at the potion that Brian had cooked.

"Wolf poison potion is a potion that can enable werewolf to maintain sanity on full moon night. If taken one week before full moon, the werewolf will remain sanity even if it becomes a wolf." Brian blinked and said.

"It's just that because the wolf poison potion is difficult to configure and the preciousness of the medicinal materials required, it has always been expensive, and it's hard for a werewolf to really afford it." Brian added slowly.

Snape nodded in slightest, his dark eyes appearing empty and indifferent.

"Your current level of potion science is in a serious state of bias," he changed the topic. "The memory and magic level are excellent, and the control of magic is quite stable. When configuring potions, it is like an extremely sophisticated machine, and there is almost no mistake. So as long as you have a formula, you can cook the finished potion well, and even the wolf poison potion can be successfully configured..."

Brian nodded slightly and listened seriously.

"But you are still at the stage of learning from others and are far from the ability to innovate yourself. This is the most important step toward potion experts and even masters." Snape said, "A master of wise potion can always make the most suitable potion according to his own needs..."

Brian nodded deeply. He understood that if his level of potion science needs to be improved from mastery to expert level, he should need to analyze the poison and create potions based on the properties of the medicine.

"To go beyond this step, talent and hard work are indispensable. You need to master more knowledge, understand the medicinal properties of all medicinal materials and their interactions, and make continuous efforts day after day..." Snape said slowly, "But for most people, it is completely enough to reach your current level."

"So, are you going to continue to study potions and explore the ultimate truth, or are you limited to daily use? So far?"

"I want to continue to study in depth, Professor Snape." Brian said seriously.

"Then you should understand that it will take a lot of your time and energy. People's energy is limited, and you have to make choices and specialize in one or two fields, otherwise you will only become mediocre in every aspect." Snape seemed very strict and authentic.

"I understand, sir." Brian said firmly. With his current ability, he was enough to study knowledge in multiple fields, and the witness point also gave him more confidence.

"Very good." Snape was silent for a long time, concise and authentic.

He took out a thick old note, which was written in a messy manner, and some parts were even dark because of the smear, and the handwriting seemed very blurred. He stroked the note gently and handed it to Brian.

"This is my research notes when I was studying potions, make good use of it." Snape said indifferently.

Brian took the notes and looked at the dirty cover, the corners of the book that had been rolled up due to long-term use and the dense thoughts and thoughts about potion cooking inside, and looked at Snape in surprise.

Of course he knew how precious the research notes of a master of potions were, which could almost be regarded as inheritance.

Snape maintained an indifferent expression and pulled out a book list of more than one meter long from the drawer and handed it to Brian: "This is a book you need to read and even remember. Some of them are in the forbidden book area, and here are my licensed signatures..."

"I'll examine the contents of your top ten books next week." Snape said slowly.

Brian took the long list of books with shame and nodded heavily.

"I understand, Professor Snape." Brian said softly, his eyes shining brightly. The professor shouted with unprecedented true feelings.

However, Snape did not let his touch stay for long, and directly rudely drove him out of the office.

Standing in front of the closed office door, Brian smiled in confusion, bowed slightly to the office door, and slowly left the place.

It was a little late, and it took a long time to boil the wolf poison potion. He came to the secret room lightly and went back directly for five hours.

"So, let's start." Brian walked around the castle model and rubbed his hands excitedly.

He plans to make a homemade map of live spots.

He can directly draw the castle map using the castle model. After so long observation and research on the castle model, Brian also mastered many secret passages and entrances and exits of secret rooms.

It is not too difficult to display the names and locations of people in the castle. It only takes a tracking spell.

After all, the map of the live spot was made by several students who had not graduated. In fact, the alchemy level contained in it is not too superb, and it is copied with Bryan's level.

But there is another problem. The map of the live spots can reveal human disguise and show its real name. For example, it can show the Petr who turned into a mouse, and Barty Crouch who used compound decoction.

Even the castle model under the secret room could not see through the real name.

For example, Brian's eyes fell on Harry's dormitory, and there were only a few names, as well as mouse spots, Toad Lafur, etc.

Through discussions with Slytherin’s portrait, they agreed that the map of the Live Spot was used as a special improved tracking technique, which may be one of the secret heritages of the Black or Porter family.

Slytherin's portrait believes that the shadow of the God-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-Snap-

Brian thinks this kind of analysis is more reliable, but he has not started to learn to capture the mind, so he only plans to use ordinary tracking techniques at present. In fact, this is enough for him.

He first made a map with special materials, and then used a pen to carve runes to draw the castle map on it. Under the command of Brian's magic wand, the pen tip quickly wandered on the paper as if there was life, and the accurate map was quickly formed.

Finally, he attached a tracing rune to it, and after more than seven hours he finally completed it.

Brian held the map and compared it with the castle model. There were successfully small black dots with names on it. Most of the small black dots were lying honestly in the dormitory. Pipi ghosts were moving back and forth in a corridor on the second floor, and mice were staying in Harry's dormitory.

Brian also found a small black dot showing "black dog" in the Beating Willow. Then the small black dot entered the secret passage below the Beating Willow and left the map range.

"It's successful." Brian exhaled softly.

"Congratulations." Slytherin's portrait blew.

Brian packed up his things, said goodbye to the portrait, avoided the patrol of Felch and Mrs. Loris, and returned to the dormitory smoothly.
Chapter completed!
