Mysterious Walker at Hogwarts

"Godfather, it's not over yet!" Dean shouted unconvinced: "Collapse!"

"Your skills are so poor! Do you only know how to use spells straight away?" Snape sneered after dodging Dean's coma spell.

Dean didn't answer, but the blackthorn wand in his left hand shook quietly.

He quietly did something bad and used a silent "Shen Feng Wu Ying" in the direction of Snape's dodge.

However, Dean knew how to measure, and Shen Feng Wu Ying did not aim at Snape's body, but deliberately missed it by a few points, but it was enough to make Snape aware of the existence of this curse.

Sure enough, after Snape avoided the coma spell, he just sneered, his expression changed slightly, and he turned around again, avoiding the silent Shen Feng Wuying.

"Shen Feng Wu Ying is a magic spell I invented. Do you think it could hurt me?" Snape felt that several of his greasy hair were cut off by Shen Feng Wu Ying.

"I'm just showing you my strength, Godfather." Dean didn't stop, "The birds are flocking!"

A flock of birds flew out of the Thunderbird wand and flew towards Snape's face.

"Split into pieces!" Snape just waved his wand casually, and the flying birds that were coming towards him were accurately crushed one by one without wasting any magic power.

Dean was completely stunned by Snape's extremely precise "roll call" spell casting method. In comparison, his method of using abundant magic to rush forward seemed so crude.

Snape took advantage of Dean's distraction and used a common "Petrified Everything" to end this duel of a school examination nature.

Snape came to Dean, who was petrified and fell to the ground, and looked at him condescendingly: "Dean, I must say, although your magic power is growing very fast, your spell-casting skills are so poor, it is simply embarrassing!"

Dean blushed with embarrassment and anger. The existence of a powerful plug-in called the system had always given him the illusion that no matter which wizard he faced, he could win with force. Just throw in a powerful spell and everything would be settled. If that doesn't work, you can also use martial arts to seize the wand and win by playing rogue.

Today's duel made Dean realize that against a truly powerful wizard, huge magic power alone is not enough. Various ingenious spell-casting skills are also essential, and this is precisely what the system cannot provide.

"Now I understand Dumbledore's intention in bringing me to this era." Snape said as he lifted Dean's petrification state.

"Professor Dumbledore asked you to come?" Dean asked in surprise.

In fact, this is not a secret. Otherwise, how could we explain that the soul time and space potion that Dean handed over to Dumbledore would appear in Snape's hand?

A piece of parchment slipped from Snape's hand and landed next to Dean's.

Dean picked up the scroll and saw the familiar Dumbledore's cursive handwriting on it: "Severus, Dean is in a little trouble. I think he needs to be better taught in spellcasting skills. There is no doubt that you are the most suitable candidate. With the soul time and space potion attached, you know how to use it correctly better than I do. Albus Dumbledore"

"I've left you to worry." Dean got up from the ground in embarrassment. It seemed that Dumbledore had seen his shortcomings from the beginning, so he sent Snape.

So... Dean began to wonder if he was deliberately pretending to be confused when he saw Dumbledore when he used the soul time and space potion last time.

"Dean, I admire your courage." Snape said, curling his lips.

Dean's heart trembled. When Snape spoke in this tone, it often meant that he was very unhappy.

"You're flattered." Dean replied cautiously.

Before he finished speaking, Snape hit him hard on the forehead with his wand - did he use the wand as a pointer?

"Have you forgotten everything I taught you before? Not all potions are suitable for use in the same container!" Snape had veins popping out on his forehead, and he was obviously extremely angry.

"I don't understand - you mean the soul time and space potion?" Dean asked in hindsight, covering his head.

"Don't you understand now?" Snape said with hatred of steel, "The raw material of the soul time and space potion uses precious time and space mithril. This is a raw material that easily reacts with other substances. It is best to use stone vessels to hold the magic potion prepared with the Mithril of Time, otherwise the potion will be easily ineffective!"

Stone vessels?Dean couldn't help but think that on Obsidian Island, Vivian indeed used a stone cup to contain the soul time and space potion.

He originally thought it was on Obsidian Island, and everything was made of obsidian. It turned out that the real reason was here!

Dean couldn't help but look a little bitter. It seemed that his knowledge was not enough, so he made such a mistake.

No wonder he didn't reach the outside of the time and space seal capsule as he wished, but arrived at King's Cross Station at about the same time...

"Godfather, I know I was wrong." Dean bowed his head and said honestly.

He knew that he must not argue with Snape, otherwise he would die miserably - even if Snape was his godfather, he would never let him go easily.

"How many times have you read the dragonskin notebook I gave you?" Snape asked again.

Dean blushed. After he traveled to this time and space, he only had more free time during the time when he was teaching Aesop carefully. Unfortunately, he did not use it to read Dragonhide Notes at that time, but spent it on those books purchased from Flourish and Blotts Bookstore. Medieval magic book.

Now that Snape asked, Dean was a little dumbfounded.

Snape snorted, and he knew the answer just by looking at Dean's expression.

"If you read the Dragonhide Notes carefully, you will see a detailed description of the mithril of time on page 719, and on page 1206 you will see the detailed formula and various taboos for preparing soul time and space potions." Snape Looking a little helpless.

Dean was not stupid enough to take out the Dragonhide Notes in front of Snape to verify his statement. The most important thing now was to calm down Snape's anger quickly, otherwise...

Dean seemed to see the tragic scene of being forced to study by Snape every day.

"Godfather, I understand. I will study the contents of Dragon Skin Notes carefully in the future." Dean smiled flatteringly.

"Well, I'll keep an eye on you." Snape's calm reply made Dean feel like he was falling into an ice cave. What he was most worried about happened.

But Dean couldn't show any resistance, and instead had to pretend to be happy: "That's great. You finally have enough time to teach me this time. - I even thought about the location of the class. Already~"

As he spoke, Dean took out the mini alchemy laboratory on the outside of the toolbox as if it were a treasure, and held it in front of Snape: "Godfather, this is a laboratory that has cast the infinite extension spell. It has all kinds of alchemical equipment. We can have classes here in the future!”

"It seems that you have already guessed that there will be a day of teaching alone~" Snape showed a rare expression of appreciation. It seemed that Dean's "consciousness" successfully impressed him.

No, that's not the purpose of getting this mini alchemy laboratory!Dean screamed deep in his heart, but he didn't dare to show it on the surface.
