People are in Hogwarts, What the hell is the flood system?

Accompanying Snape's cold incantation, horrifying wounds suddenly appeared on the suit of armor that Harry had previously hung upside down.

It was as if invisible blades were moving back and forth across the armor.

It wasn't hard to imagine what it would look like if it were a human body.

Harry's face suddenly turned pale.

Previously, he had only heard about the horror of dark magic from the professors' lectures, but only by witnessing it firsthand did he understand how extreme the spells labeled as dark magic were.

Even the "gentle" Sectumsempra that Snape spoke of was enough to cause great harm!

For a moment, Harry hesitated whether or not he should learn this spell.

Frankly, he felt that spells like disarming others were more suitable for him.

At this time, Snape was also watching Harry.

Seeing the obvious hesitation in Harry's eyes, a deep bitterness slowly flashed across Snape's eyes.

Sure enough, he was Lily's child, so similar, with the same resistance to dark magic.

Recalling how dark magic had gradually estranged him from Lily, Snape couldn't help but clench his fists, regret surging in his heart, as he coldly uttered a sentence to Harry.

"If you don't want to learn, then don't."

"Dark magic is only used by dark wizards, they are all scum and dregs, don't associate with them."

"Potter, your choice is correct."

"Alright, today's detention ends here..."

Just as Snape was feeling frustrated and wanted to banish these unpleasant sights from his mind, returning to his small office to "cherish" Lily's photo, Harry seemed to have made some kind of determination and chanted the spell towards the suit of armor.

"Sectumsempra!"

A shallow wound appeared on the armor.

Snape was stunned for a moment, and Harry looked at him with trusting eyes.

"Professor, you are my mother's friend. Although I don't know exactly what happened, I believe that even if you know dark magic, and even if you are the Head of Slytherin, and even if you always deduct points from Gryffindor for no reason, and even if you don't wash your hair..."

As Snape's face grew darker and darker, Harry smiled.

"But I think you must be a trustworthy and good person."

"I will practice Sectumsempra diligently, Professor."

The corners of Snape's mouth unconsciously curled into an almost imperceptible arc.

At this moment, Harry cautiously pleaded.

"Professor, can you also teach Leien Stupefy and Sectumsempra? He is my best friend."

Snape frowned, glanced at Leien, and suddenly sneered.

"When I was teaching you just now, I didn't lower my voice."

"So I think you don't need to worry about your friend. With Leien Snow's talent, he must have already learned it after listening to it once, right?"

Leien, who had been processing potion ingredients, calmly raised his head and nodded to Snape and Harry.

"That's right, I have already learned both Stupefy and Sectumsempra."

In the next moment, Leien gently waved his wand.

"Stupefy."

"Sectumsempra."

The poor suit of armor flew high towards the ceiling, and the next second it was dismembered into eight pieces by invisible blades, falling to the ground with a clatter.

A hint of surprise couldn't help but appear in Snape's eyes.

He had expected Leien's speed in mastering spells.

After all, he was a genius who could master Transfiguration to that extent in the first year, so it was only natural for him to quickly learn these two spells.

But this magic power, it didn't seem like it should be the level of a first-year student.

Even Harry's magic power was inferior to Leien's?

Snape quickly walked towards Leien, his sharp eyes scanned the materials Leien was processing for the Color-Changing Potion, and then fell into silence again.

These materials were not common materials. At least they would only be recorded in potion textbooks for fifth-year students and above, and the processing methods were extremely complicated.

When Snape asked Leien to process them, he was actually prepared to lose everything.

If even one or two materials could be processed to a usable state, he would think that Leien was indeed a promising talent in potions, and for Harry's sake, it would be worth cultivating him a little.

But now, the processing results of the several materials presented in front of Snape were even more perfect than those in the textbook, without the slightest mistake.

Even if Snape himself were to process them, he couldn't do better.

This caused Snape's brows to furrow, and a trace of vigilance and hostility slowly emerged in his eyes as he looked at Leien.

He slowly clenched his wand, imperceptibly moving his feet, using his body to shield Harry.

It wasn't that Snape was jealous or threatened by Leien's talent. As a potions master, he had his own arrogance and was not so petty.

What truly made him vigilant was that Dumbledore had revealed to him that when Harry entered Hogwarts, perhaps the gears of fate would begin to turn, and that person's return would be getting closer and closer.

Perhaps Voldemort was attached to someone in Hogwarts!

And Leien's performance couldn't help but make Snape have such doubts, perhaps Voldemort was controlling this body at this moment!

Then Leien deliberately approached Harry Potter and became Harry's best friend, just thinking about it was creepy.

A trace of killing intent had already begun to churn in Snape's heart.

At this moment, Leien also frowned, sensing the killing intent emanating from Snape, and even the relationship with Grand Supreme Elderly Lord on the system light screen had fallen from friendly to enemy.

It even started with extreme animosity, and was still sliding towards an irreconcilable relationship?

"Professor, are you misunderstanding something?"

Leien looked at Snape sincerely.

"I admit that I'm a little handsome, a little talented, and a little strong in magical talent, but I, Leien Snow, just want to become a social butterfly at Hogwarts, with friends all over the world."

"Don't misunderstand me."

Snape sneered.

"With your potion level, as long as you can get the materials, what is a Color-Changing Potion? Polyjuice Potion is probably also within reach, do you still need me to guide you?"

"You better tell me your real purpose."

Leien sighed.

"That's right, the Color-Changing Potion is not difficult for me, and the Polyjuice Potion is also easy to make."

"What I really need to ask a potions master like you for guidance on is another potion."

In the next second, Leien's body suddenly blurred and appeared beside Harry.

While Harry hadn't reacted at all, not knowing how the atmosphere had become like this, Leien knocked him unconscious with a light chop.

Snape let out a furious roar.

"Let him go!"

"Sectumsempra!"

A Sectumsempra that was much stronger than when he showed Harry flew towards Leien in fury.

Leien took a deep breath, his hair suddenly danced wildly, and a layer of sacred gold appeared on his body.

Sectumsempra? It was indeed a dark magic spell with considerable lethality.

But after obtaining the Vajra Body and not being stunned, plus the Earth Spirit Nascent Soul and the newly acquired Night Wraith talent, Leien's resistance to magic had reached an incredible level.

He casually blocked it, accurately meeting the invisible Sectumsempra spell that was coming.

The Sectumsempra spell, which could easily cut steel, dissipated like a bubble after touching Leien's golden body!

Even with Snape's battle-hardened experience, he felt his worldview was impacted at this moment.

Hard resist the Sectumsempra spell?

Even a fire dragon doesn't have such high magic resistance!

Leien Snow, what kind of monster is this?!
