Hogwarts: The Savior's Strong Cousin

"No way, I did it strictly according to the instructions."

Dudley scratched the back of his head, pulled out the stirring stick, which had also turned black, and threw it on the table.

The wooden table soon began to make a hissing sound as if it was corroded.

The corners of Severus' eyes were twitching, and he pointed at Dudley tremblingly, but when he thought of his "heroic appearance" of beating Goyle and Crabbe that day, he couldn't help but take a step back.

"Recite the steps again."

Forcing his tone to be normal, Snape began to laugh at Dudley's joke.

Is it okay if I can’t humiliate you in person and let you suffer a little in front of your classmates?

Sarcasm is a traditional virtue of our British wizarding world and it is something that must be savored.

Dudley cleared his throat.

"Put two drops of water from the River of Forgotten into the crucible and heat it for two minutes."

"Now add two valerian sprigs and stir clockwise three times."

"Wave your wand and leave it alone for an hour."

"Ten minutes in advance, add two parts of standard ingredients and four parts of parasite berries to a mortar and pestle, crush into a fine powder, and divide into two portions."

"Add both powders to the crucible, stir counterclockwise five times, and wave your wand."

"Have I made myself clear enough, Professor Snape?"

Snape had a dark face and said nothing, because the steps described by Dudley were completely correct. He even took the effects of the medicine into consideration and ground it in advance. The finished product at this stage was also a perfect work with the best medicinal strength.

However, even if a Muggle were to do this step, there would be no problem. How could it turn into such a - hideous liquid?

Snape looked at the strange liquid in front of him and found it hard not to think of the asphalt that Muggles used to pave roads.

"Try it. Maybe it tastes good but doesn't look good."

Dudley sat down. The waiting process was so long that he almost fell asleep.

In fact, he did oversleep, but Hermione, Harry and others were busy making medicine in the distance, so which student dared to mess with him? Naturally, after an hour and a half, the potency of the medicine had reached a strange level.

Severus gritted his teeth. He was definitely going to lose this point from Gryffindor today.

Touching the antidote on his chest, Snape gritted his teeth, stamped his feet, reached out and scooped out a spoonful of "forgetfulness potion".

"You are so rude, professor. You should use a serving spoon!"

Dudley soon made the expected sound, and the students couldn't help but laugh - even in the class of Professor Snape, who had a sullen face.

Snape ignored him, swallowed his saliva, and drank the potion in the bowl with his head tilted back.

Then, the students nearby saw an extremely rare scene.

Snape's face first turned red, then turned visibly black. Strange wisps of white smoke floated out of his mouth and nose. Severus' eyes turned red. He immediately took out the antidote, trembling, and drank it in one gulp. His complexion immediately returned to normal.

Then, the head of Slytherin, an experienced Potions teacher, drew out his wand, pointed it at his head, and a ray of silver light flowed out like a snake.

"I know this. This is a spell to extract memories."

Miss Granger was an encyclopedia indeed, and she quickly spoke up to tell the confused students around her.

Snape shook off the memory, coughed twice, and stared at Dudley with burning eyes.

"Damn, what the hell are you?"

Feeling that the taste on the tip of his tongue seemed to have not yet disappeared, Severus casually got a pool of clean water and rinsed his mouth.

"Potion of Oblivion, Professor."

Dudley shrugged.

"Look, isn't this memory gone from you now?"

Severus Snape froze in place.

Indeed, a normal amnesia potion can make people forget certain things that happened during a certain period of time.

After the students realized what was happening, they burst into laughter that almost broke the roof.

After the commotion, Snape didn't even check other people's homework and just flew away.

However, Dudley managed to pass the Potions exam.

The last class, History of Magic, was all rote memorization. Our dear Mr. Dursley apparently only memorized one answer, so he naturally passed it easily.

After all, a feather pen that prevents cheating cannot prevent spoilers.

"It's so refreshing. I never thought I would be able to pass the exam one day."

Dudley touched his shiny bald head and took out a wine flask filled with mead from his arms.

After all, butterbeer was just a sweet drink with a little bit of alcohol. With Dudley's body, even if he drank it with extremely high-purity alcohol, it wouldn't make him too drunk.

Judging from the popular drinks in Hogwarts, it is still difficult for students under the age of seventeen to get some fire whiskey, so Dudley can only enjoy this "children's drink".

"Are you satisfied with this? You have to know that there will be OWLs exams in the future. Your mentality is wrong."

Miss Granger, the queen of rolls, naturally has a different opinion.

Although she still didn't understand why Dudley, who was so smart, would pretend to be so strong.

However, for some psychological reason, Hermione did not expose Dudley's disguise.

This was something even his cousin Harry hadn't noticed.

“What are OWLs?”

Harry was curious about everything in the wizarding world, and this time, Ron was the one who answered his questions.

Generally speaking, this is the "Ordinary Wizarding Level Test", or in Dudley's words, the "professional qualification certificate". For most wizards who need to "take the civil service exam", that is, to work in the Ministry of Magic, the results of OWLs are particularly important.

There are many standard subjects for measuring performance, most of which are astronomy, care of magical creatures, spells, defense against the dark arts, divination, herbology, history of magic, potions, transfiguration, ancient runes, etc. The more talented the wizard is, the more certificates he will choose to obtain.

"Anyway, I won't take the Divination exam. It's an inaccurate subject."

Hermione muttered.

Dudley secretly complained in his heart, wondering whose Arithmancy Divination class could get an "O" which represents excellence.

Although arithmetic divination is more similar to Dudley's previous life's "divination", reasoning about things based on hexagrams or numbers, overall, it still tends to be metaphysical.

"Wait, I suddenly remembered..."

"Why is it that Hagrid, who wanted a dragon the most, happened to win the bet in the tavern?"

"And that stranger happened to have a dragon egg in his pocket?"

"And who are the people who walk around with dragon eggs every day? That's against wizard law!"

"Isn't it too coincidental?"

Harry suddenly spoke up, finally realizing the answer he had been struggling to come up with these days.

Everyone was shocked, except Dudley, who took a sip of mead and burped at an inopportune time.
