A certain Hogwarts professor of runes

Nighttime, the edge of the forbidden forest.

Harry, Ron, and Hermione hid in the bushes at the edge of the Forbidden Forest, constantly peering towards the castle.

Hermione said somewhat anxiously, "I don't think we should doubt the professor..."

Ron quickly said, "Hermione, we've learned this the hard way. Remember Professor Quirrell in the first year? Who would have thought that this cowardly and weak man actually had a Dark Lord stuck to the back of his head?"

"But that doesn't mean other professors—" Hermione tried to argue her point and defend the professor she admired.

"Think about Lockhart. He may not be a dark wizard, but he's definitely not a qualified professor. Harry, have you forgotten that you played a vampire in Defense Against the Dark Arts class?"

Harry thought for a moment and suddenly felt nauseous.

So Harry whispered to her, "We're not suspicious, we're just curious to see what he's doing in the Forbidden Forest. That way we can eliminate one suspect, and we can even ask Professor Hyp for help."

Hermione remained silent.

The three hid in the bushes. The November night was already a bit chilly, and the thin mist intensified the feeling of cold.

Ron was stiff with cold, and he said tremblingly, "Maybe he won't come tonight. Shall we go back?"

"Wait a little longer," Harry said patiently.

A while later, it was almost midnight.

A tall figure walked out of the castle.

"Someone's here! It's Professor Hep!" The three of them were excited; their wait hadn't been in vain.

On the other side—

Felix left the castle and headed toward the Forbidden Forest.

A cool night breeze felt wonderful on my face.

He reached the edge of the forbidden forest and immediately noticed that something seemed to be watching him.

Small animals? Wildlife from the forbidden forest?

But they shouldn't appear on the edge of the forbidden forest.

Felix took out his wand, and light shot out from the tip of the wand. A dozen milky white light spots flew out and then quickly exploded, illuminating the Forbidden Forest within a radius of a hundred meters.

There was nothing there.

He found it strange and followed his senses to a large tree, where he examined it closely.

After a while, he chuckled softly.

Across from them, the three little ones, draped in Harry's Invisibility Cloak, barely dared to breathe, their faces filled with tension as they stared at the professor.

Harry could even feel his legs trembling, and Ron's hot breath was blowing on his face.

Fortunately, the professor didn't suddenly reach out and lift their invisibility cloaks. He brushed past them and walked into the Forbidden Forest.

"Huff~ Huff!" The three of them were panting heavily.

"Did he find out?"

"Probably not."

"Maybe we should go back," Ron suggested, backing out.

"No, let's continue." At this point, Hermione decided to stick to it.

So the three of them, holding up an invisibility cloak, followed the professor step by step.

Felix wasn't moving fast; he fiddled with his wand, a strange feeling creeping into his mind.

The trio, the main characters, what kind of "plot" is going to happen today?

There were too many flaws: the disordered footprints next to the tree, the faint breathing sounds, and his intuition all gave away the three people's location.

But what truly made him recognize the trio was the smell of his assistant's shampoo.

This is also why Felix didn't expose him on the spot.

Felix continued towards his intended destination, only to find three people following behind him, which surprised him. "Is my target?"

Well, let's take this opportunity to get to know the other two "protagonists".

About half an hour later, Felix arrived at a clearing deep in the Forbidden Forest and stopped.

About thirty or forty meters apart, Harry, Ron, and Hermione also hid behind a large tree. "What is he going to do?"

"Shh!"

Felix raised his wand and flicked his wrist, striking the stones with three crimson spells. To the astonishment of the three people watching from the sidelines, the three stones transformed into three large black dogs.

The large dogs were half a person's height, their fur glossy and smooth, like the finest black velvet. The three large black dogs shifted slightly, then fixed their gaze on Felix, lowering their limbs, baring their teeth, their eyes filled with aggression.

"Quite advanced shapeshifting techniques... Look, they're practically alive," Hermione commented quietly.

"I don't care about his Transfiguration skills, I just want to know what he's doing in the Forbidden Forest," Ron muttered, but he kept his eyes glued to the screen.

However, what happened next took them by surprise: three large black dogs charged at Professor Hyp simultaneously, launching an attack on him. They were incredibly fast, covering the distance of over ten meters in the blink of an eye.

"Ah!" Hermione couldn't help but scream. From her perspective, the big black dog's fangs were less than three feet away from Professor Hyp.

But Felix did not dodge; instead, he uttered a spell with a deft touch.

Hermione was extremely anxious; even if she could block one large dog, there were still two more. Harry and Ron also wore expressions of horror, especially Harry. A year had passed, and yet another professor had died before his eyes?

However, they had clearly forgotten that the three large dogs were all transformed from the professor.

In a split second, the situation on the field changed dramatically.

Felix's figure vanished abruptly, leaving behind a puff of black smoke. The next instant, he reappeared two meters away, and as soon as he appeared, a beam of red light shot out from his wand. His figure disappeared simultaneously, reappearing in another corner, where he also cast a spell.

In the eyes of the three, the professor seemed to transform into three in an instant, simultaneously casting three spells.

"Bang!"

"Bang!"

"Bang!"

The three large black dogs fell to the ground instantly, struck by the curse.

Under the invisibility cloak, they stared in disbelief.

"My God, what kind of magic is that!" Ron exclaimed, his mouth agape, still replaying the scene in his mind.

Amidst the black smoke, the professor's cold, stern face appeared with a flash of red light, then vanished in the blink of an eye in another location. This speed was so fast that it was impossible to dodge or defend against.

Harry's eyes widened as well.

In the center of the open space, Felix, who had just finished casting his spell, shook his head. It still didn't work; he was off by half a meter.

This is only two jumps. If it happens ten or eight times, wouldn't he be more likely to be hit by his own curse?

Felix's reason for emerging was actually to refine his Trinity Raid tactics, which he named the "Instant Kill" technique during his adolescent rebellious phase.

The principle is very simple: the trinity, which means that the three spells are used at the same time and perfectly integrated, so that the effect of one plus one plus one is far greater than three.

The speed of "Apparition", the power of "Petrification", and most importantly, the "Mind Acceleration" that maintains one's balance and reaction ability.

When combined, Felix can unleash spells from a dozen different locations in an instant, creating a magnificent crossfire line, achieving the terrifying effect of one person being a whole squad.

The principle is indeed very simple, but the path is extremely difficult.

The difference lies in how to improve one's reaction speed and how to maintain body balance in an instant.

At the beginning of the semester, he developed the prototype of this magic, or rather, a branch technique—"Mind Hut," but it could only be used as a teaching technique. Now, more than two months have passed, and he has not been idle during this time.

Hermione was practicing runes in the Mindroom, and he was also in the Mindroom devising how to apply them in battle.

Fortunately, he has gained a lot of insights recently.

This is why he ventured deep into the Forbidden Forest for several days in a row—to avoid the ubiquitous Anti-Apparition Spell within Hogwarts Castle!

"Two jumps, barely acceptable." Felix was fairly satisfied, considering there would be improvements later.

Then, he raised his head and looked steadily in the direction of the trio.

"Come out."
