Being at Hogwarts, something's not right with this system.

Snape should have just been staring at Harry.

But since Lin Yu had offended him, Lin Yu actually received the "honor" that should have belonged to the protagonist.

Fortunately, Snape quickly looked away, as he fixed his gaze on Harry again and asked, "Potter, what would I get if I added narcissus root powder to wormwood infusion?"

Harry glanced at Ron beside him, only to find that Ron, like him, had a clear but foolish look in his eyes.

In fact, it wasn't just the two of them; the entire classroom was completely silent, except for Hermione.

She was raising her hand high.

Lin Yu blinked. As expected of a female academic genius, he was actually also confused.

Lin Yu had flipped through those textbooks before the start of the semester, but he still didn't understand what Snape was talking about.

So it's not that they were too stupid, but that Snape's question was beyond their level.

In fact, Harry did read a few books in his spare time during the month before school started.

However, he still didn't know the answer.

So Harry could only awkwardly reply, "I'm sorry, Professor, I don't know."

Even with Harry in this state, Snape still scoffed, "Looks like fame doesn't work."

Harry immediately sensed the hostility in Snape's tone, and he didn't understand why he was being targeted.

But Snape wasn't about to let him off the hook, and continued, "Potter, if I asked you to find me a gallstone, where would you go?"

Harry could only shake his head helplessly; he clearly didn't know the answer either.

He didn't even know what bezoar was.

So all he could say was, "I'm sorry, I don't know."

Draco and his two henchmen were practically laughing their heads off.

Lin Yu sighed helplessly. Poor Harry, this is truly a case of the son paying for the father's sins.

Lin Yu knew perfectly well why Snape was targeting Harry: it was because Harry's father, James Potter, was a student of Snape's and they were at odds.

Just like Harry and Draco Malfoy are now.

Wait, Lin Yu suddenly remembered something and subconsciously looked at Draco.

Sure enough, Draco seemed to sense something and immediately turned to glare at Lin Yu.

Compared to Harry, Lin Yu felt that the guy was more hostile towards him now?

"It seems you haven't even opened a book before school started, Potter. Your reputation isn't something to be complacent about," Snape's voice came from the front. He said coldly, "I'll give you one last chance. What's the difference between Aconitum carmichaelii and Aconitum kusnezoffii?"

Harry finally couldn't hold back any longer and said, "I don't know, but why don't you ask someone else? Maybe they know? Like Hermione."

Harry turned his head and saw Hermione's hand raised high.

Hermione wasn't very tall to begin with, but she almost stood up.

However, Snape seemed not to see Hermione's hand until this moment, when he turned and roared, "Put your hand down!"

Lin Yu frowned and stood up abruptly.

He didn't want to meddle in other people's business, since he was likely to provoke Snape in the future, and he didn't want to get into trouble for now.

However, he couldn't stand it anymore and shouted, "What? Harry's reputation can't be taken for granted, so you were born more than ten or twenty years before us, and just because you learned these things earlier, you can be proud of yourself and use them to swagger around and suppress others? Before you learned this knowledge, what were you?"

"What did you say?" Snape was shocked and looked at Lin Yu in disbelief, as if he couldn't believe that a student, especially a first-year student, would talk back to him like that.

Lin Yu sneered. He hadn't wanted to speak, but he couldn't bear Hermione's reddened eyes, so he said, "Or you could ask Malfoy? Maybe he knows the answer? If he doesn't, why are you targeting us? Or did the professor who taught you everything he knew at Hogwarts teach you the same way? Did he use advanced knowledge to target you in class, even in your first class of the new semester? And then point his finger at you and say, 'Snape, you're trash.'"

Lin Yu actually has a bit of a bad temper, which can be seen in some things.

For example, on the train, even though it was Draco who was causing trouble, Lin Yu also vehemently criticized what Ron said, which could be considered a warning.

Even at the Sorting Ceremony, he would not compromise, daring to confront Snape in front of the entire school, and even confront all the students of Slytherin House.

He would rather challenge Filch to a duel than be insulted.

In his past life, he was an ordinary person who had no choice but to compromise when necessary and dared not provoke those he could not afford to offend.

But now that he's already traveled through time, if he continues to compromise, wouldn't his time travel have been for nothing?

Having died once and now possessing the second level of Qi Refining, Lin Yu is not about to back down.

More importantly, Lin Yu was personally experiencing this conflict, and he really couldn't stand by and watch.

Before Snape could react, taking advantage of the moment Snape was stunned by Lin Yu's words, Lin Yu shouted, "Just because you got caught in the rain doesn't mean you should tear other people's umbrellas to shreds! Although the British don't seem to like using umbrellas, why drag the grudges and feuds of the previous generation into the next? Besides, you lost your lover yourself; you deserve to lose your beloved forever. Snape, didn't you kill them? Who are you really blaming?"

Harry Potter's parents, Lily and James, were killed by Voldemort.

However, the reason Voldemort wanted to kill Lily and James was because Snape had heard a prophecy that mentioned Voldemort would be defeated.

However, Snape only heard half of the prophecy and never imagined that it would lead to the death of his most beloved woman, Lily.

Snape and Lily were childhood sweethearts, having known each other even before they went to Hogwarts.

Snape was sorted into Slytherin, while Lily was sorted into Gryffindor.

But what hindered them and separated them was not the relationship with the House, but Snape's wrongdoings and words.

Snape was ambitious and pursued the allure of dark magic throughout his life. He had already begun associating with the Death Eaters during his student days.

Many people who haven't read the novels might think that Snape was bullied by James.

But in reality, if James is a petty thug, then Snape and his gang are the truly dangerous ones.

Even the spell James used to bully Snape, the upside-down bell, was a dark magic invented by Snape.

Most importantly, Snape said something to Lily that can never be forgiven, and that was...

Snape once called Lily a "Mudblood".

Therefore, Snape lost his love on his own, he has no one to blame but himself, he deserved it.

(P.S.: I previously wrote that Snape called the protagonist Mudblood, but after readers pointed it out, I made a slight revision. Just to clarify again, because of Lily's incident, Snape should never utter the word "Mudblood" again. Sorry about that.)
