"What?" Hermione's voice went up two octaves as she stared at Chen Yu, incredulous.

Her gaze was exactly like the one she gave Harry and Ron after they caused trouble.

"Chen Yu, why would you so unwisely agree to Malfoy's provocation? Have you forgotten how Malfoy stood up Harry and Ron? He's a treacherous villain, you shouldn't pay any attention to his provocations!"

After speaking, she went to pull Chen Yu's arm, wanting to drag him out of there, and glared angrily at Malfoy.

Malfoy was the culprit behind everything.

If it weren't for Malfoy, Harry and Ron wouldn't have been out at night, almost getting caught by Filch.

If it weren't for Malfoy, they wouldn't have stumbled into Fluffy's room in a panic and been scared half to death.

If it weren't for Malfoy, her relationship with Harry and Ron wouldn't be so strained, making her so angry she didn't want to talk to them.

"Hmph, that's because they're stupid!" Malfoy snorted coldly, then continued in an arrogant tone, "It's you 'Mudbloods' who are polluting the 'purity' of wizards. Today, I'll show you the power of pure-blood wizards!"

After speaking, he gestured to his two cronies to block Hermione, not allowing her to leave either.

Hermione's parents were Muggles, so she didn't understand the exact meaning of 'Mudblood' in Malfoy's mouth, but from Malfoy's expression, she knew he wasn't saying anything good.

Chen Yu, however, knew that it was a derogatory term used by pure-blood wizards for half-blood wizards, equivalent to calling someone a "bastard."

It was a very insulting remark.

Chen Yu pulled Hermione behind him; with Chen Yu's current strength, Hermione was completely unable to resist and was protected behind him.

"'Mudblood' this, 'Mudblood' that, you're looking for death, Malfoy. I originally only wanted to teach you a small lesson, but it seems you'll have to suffer a bit more."

After speaking, Chen Yu pushed the two cronies blocking him aside and led Hermione upstairs.

"I know there's an abandoned classroom on the second floor where no one goes. Aren't you going to have a wizard's duel? If you've got guts, then follow me!"

Malfoy's face darkened after hearing Chen Yu's words. He glared at the two cronies who failed to stop Chen Yu and Hermione, then strode quickly after them.

Chen Yu pulled out his wand, ready to act first before Malfoy could make a move.

After he and Hermione went upstairs, they twisted and turned until they finally reached a secluded room that usually had few visitors.

Chen Yu opened the door, dust flew up, and he walked into the room first.

Malfoy pinched his nose and waved his hand to clear the dust in front of him, once again displaying his disdain and arrogance:

"Is this the place you chose? Dilapidated and broken, it certainly has the characteristics of you Mudbloods. Mudbloods, it's best to rot in the mud!"

Chen Yu did not take out the Serpent Spell or the destroyer hat from his backpack; using those two items would be too much bullying for Malfoy.

He raised his wand and said to Malfoy, "Are you done talking? If you're done, can we start? One-on-one or group fight, you choose."

Hearing Chen Yu say one-on-one or group fight, Malfoy cautiously glanced at his surroundings.

He was genuinely a little afraid that Chen Yu would give an order, and a dozen Little Wizards would rush out from behind the desks and chairs to righteously gang up on the three of them.

But after a few glances, he didn't find any place in the classroom where people could hide, so he retorted, "What is one-on-one? And what is a group fight?"

Chen Yu twirled his wand twice like a pen and said, "One-on-one means I'll fight the three of you alone, and a group fight means I'll gang up on the three of you alone!"

These words infuriated Malfoy, who immediately pointed his wand at Chen Yu and shouted, "How arrogant! I'll make you taste my power! Relashio..."

"Wait a moment!"

Seeing Malfoy preparing to cast a spell, Chen Yu quickly called a halt.

Malfoy didn't finish the curse, raising his eyebrows as he looked at Chen Yu, thinking Chen Yu had chickened out.

"I think a simple duel is boring. How about we add a wager?"

"What wager?"

"The loser must do one thing for the winner, how about it?"

"Good suggestion, I agree! Relashio!"

Malfoy revealed a sinister smile. As soon as he agreed to Chen Yu's proposal, he immediately used the Relashio Charm, wanting to make Chen Yu lose face in front of the girl.

Chen Yu had been watching Malfoy closely, and seeing Malfoy use a curse, he immediately cast four spells.

"Protego!"

"Expelliarmus!"

"Petrificus Totalus!"

"Levicorpus!"

The first spell transformed into a transparent wall, blocking Malfoy's curse and deflecting it back.

Malfoy hadn't expected Chen Yu to know the Shield Charm. In his shock, he was hit by the reflected curse.

His face instantly changed, and he felt his intestines begin to cramp violently.

A surge of "primordial power" was about to erupt.

And at this moment, Chen Yu's remaining three spells arrived.

Expelliarmus directly knocked the wand from Malfoy's hand, rendering him unable to fight further.

Petrificus Totalus turned the two cronies behind Malfoy, who were preparing to help, into stiff wooden figures, falling straight to the ground.

Levicorpus left Malfoy dangling upside down in mid-air in a very undignified posture.

By the time Malfoy reacted, he was completely bewildered.

He hadn't expected the "Mudblood" in his eyes to know so many spells. By the time he reacted, he had already lost the ability to fight back.

Though humiliated, Malfoy was unyielding and did not beg for mercy. Instead, he loudly clamored, "Put me down! You damn Mudblood! This doesn't count, you haven't followed the rules of a wizard's duel at all! We're supposed to stand opposite each other, bow to each other, and then raise our wands before a glorious duel!"

"You were the one who attacked first, weren't you, Malfoy!"

Hermione looked at Malfoy, who was hanging upside down, and was furious. She picked up her wand and tapped Malfoy's inverted head twice to make him quiet down.

Judging from Malfoy's initial attack, he had no intention of following the rules of a wizard's duel. Now that he had lost, he was clamoring about not adhering to the rules.

Heh, what an ugly face.

"You damn Mudblood, how dare you hit me! You just wait, I'll have my father get you expelled from school!"

Malfoy tried to continue his rant, but Chen Yu's next words made him shut up completely.

"Shut up, Malfoy. Say 'Mudblood' one more time, and I'll use the Tongue-Tying Curse to make sure you can't utter another word!"

Chen Yu said impatiently to Malfoy.

Then, staring at Malfoy's head, he said, "I remember that in a wizard's duel, one party must be completely defeated to win. You always consider yourself a noble 'pure-blood' wizard. I wonder if sleeping eternally in a wizard's duel counts as an honor?"

Seeing Chen Yu's serious gaze, Malfoy swallowed hard.

This kid seemed to be seriously considering death as the outcome of this wizard's duel.

Malfoy immediately understood a widely circulated proverb from the ancient East: "A wise man submits to circumstances."

Malfoy decisively conceded, "I admit I lost!"

Chen Yu naturally wouldn't let Malfoy off so easily. He grinned at Malfoy, "Since you concede, that means I've won. I remember you 'pure-blood' wizards have accumulated a lot of wealth, right..."

Hearing Chen Yu say this, Malfoy's eyes widened. He thought Chen Yu was going to extort a large amount of Galleons or potion ingredients from him. While his heart bled, he also prepared for Chen Yu's exorbitant demands.

"Then help me get the spell books and notes from your home that record the Fiendfyre, Legilimency, Occlumency, Undetectable Extension Charm, and Confundo. Preferably with annotations!"

Among these spells, Chen Yu hadn't found any relevant records for any of them except the Confundo in the Library.

He had found books related to the Confundo, but the content was quite profound, and he hadn't fully understood it yet.

That's why he wanted books related to the Confundo with annotations, to consult other books' explanations of the Confundo.

After all, stones from other mountains can be used to polish jade; it's always good to consider other people's ideas.

Seeing Malfoy nod in agreement, Chen Yu released "Golden Bell Landing" to cancel the "Levicorpus" state, letting Malfoy drop to the ground.

As soon as he landed, there was a "splat," and something seemed to slide out of Malfoy's pants.

Hermione, Chen Yu, and Malfoy's faces instantly changed.

Hermione and Chen Yu knew the effects of the curse Malfoy had cast.

It was the Relashio Charm, a spell that could make a person drop what they were holding, or cause items to repel internally and separate.

However, Little Wizards often used it as a prank spell to extract accumulated feces from the target's body, causing forced excretion.

A Gospel for those with constipation, a nightmare for those with social anxiety.

Especially in public, once hit by this curse, one would evolve from social anxiety to social death.

Seeing Malfoy agree, Chen Yu pulled Hermione and started to walk out.

He didn't want to stay in this broken classroom for a second longer; he feared that soon, the entire classroom would be filled with Malfoy's scent.

Just as Chen Yu stepped out of the abandoned classroom door.

Malfoy's faint plea sounded in Chen Yu's ear.

"Please... don't tell anyone about this..."

"Then agree to one more thing."

"Okay... okay..."

Malfoy's voice was very faint, but he still managed to agree to Chen Yu's condition with difficulty.

Alas, this poor child.

An ant trying to shake a tree, a praying mantis trying to stop a chariot.

Of all the people to be arrogant with, he had to pick on himself.

Now he's just run headfirst into a brick wall.
