At night, on the edge of the Forbidden Forest.

Harry, Ron and Hermione hid in the bushes by the Forbidden Forest, looking towards the direction of the castle.

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

Ron said quickly, "Hermione, we have suffered losses in this regard. Remember Professor Quirrell in the first year? Who would have thought that he, who was timid and cowardly, actually had a Voldemort stuck behind his head?"

"But this does not mean that other professors--" Hermione tried to argue and defend the professor she admired.

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

Harry thought about it and suddenly felt nauseous.

So Harry whispered to her, "We are not suspicious, but curious. Let's see what he is doing in the Forbidden Forest. This can also eliminate a suspect, and we can even seek help from Professor Hep."

Hermione stopped talking.

The three of them hid in the bushes. The November night was already a little cool, and the thin mist aggravated the feeling of coldness.

Ron was so cold that his body was a little stiff. He said tremblingly, "Maybe he won't come tonight. Otherwise, let's go back first?"

"Wait a little longer." Harry said patiently.

After a while, it was almost midnight.

A tall figure walked out of the castle.

"Someone is coming. It's Professor Hepp." The three of them were excited. Finally, they didn't wait in vain.

On the other side,

Felix left the castle and headed towards the Forbidden Forest.

A cool breeze at night blew on his face, which felt very comfortable.

He came to the edge of the Forbidden Forest and immediately found that something seemed to be watching him.

Small animals? Forbidden Forest creatures?

But they shouldn't appear at the edge of the Forbidden Forest.

Felix took out his wand, and the tip of the wand sprayed light. More than a dozen milky white light spots flew out and then exploded quickly, illuminating the Forbidden Forest within a radius of 100 meters.

Nothing.

He felt a little strange. He followed his feeling to a big tree and looked at it carefully.

After a while, he laughed softly.

On the opposite side, the three little ones were wearing Harry's invisibility cloak. They didn't dare to breathe and looked at the professor opposite with nervous faces.

Harry could even feel his legs shaking, Ron's hot breath spraying on his face.

Fortunately, the professor did not suddenly reach out to lift their invisibility cloak. He brushed past them and walked into the Forbidden Forest.

"Hoo~Hoo!" The three of them panted heavily.

"Did he find out?"

"Probably not."

"Or, let's go back." Ron backed out.

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

So the three of them held up an invisibility cloak and followed the professor in small steps.

Felix's speed was not fast. He fiddled with the wand in his hand, and a strange feeling arose in his heart.

The trio, the protagonist group, what "plot" is going to happen today?

There are too many flaws. The disordered footprints next to the big tree, the subtle breathing, and the intuition brought to him by the dark, all exposed the location of the three.

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

This is also the reason why Felix did not expose them on the spot.

Felix was heading for his intended destination when he found that three people were following him. He was a little surprised. Their target was me?

Well, he could use this opportunity to get to know the other two "protagonists".

About half an hour later, Felix came to an open space deep in the Forbidden Forest and stopped.

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

"Shh!"

Felix raised his wand, waved his wrist, and three red spells hit the stone. Under the astonished eyes of the three people outside, the three stones turned into three big black dogs.

The big dogs were half a person tall, with shiny fur all over their bodies, like the finest black velvet. The three big black dogs moved their bodies slightly, then aimed their eyes at Felix, with their upper limbs lowered, their teeth bared, and their eyes full of aggression.

"Very advanced transformation skills... Look, they are almost like alive." Hermione commented in a low voice.

"I don't care about his Transfiguration skills, I just want to know what he is doing in the Forbidden Forest." Ron muttered, but he also watched intently.

However, what happened the next moment surprised them. Three big black dogs rushed towards Professor Hep at the same time and attacked him. They were extremely fast, and they broke through the distance of more than ten meters in almost the blink of an eye.

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

But Felix did not dodge, but cast a spell lightly.

Hermione was very anxious. Even if she blocked one big dog, there were still two others. Harry and Ron's faces were also filled with fear, especially Harry. After a year, another professor died in front of him?

However, they obviously forgot that the three big dogs were all transformed by this professor.

In a second, the situation on the field suddenly changed.

Felix's figure suddenly disappeared, leaving a cloud of black smoke on the spot. The next moment his figure appeared two meters away. As soon as he appeared, a red light shot out from his wand. His figure disappeared at the same time, and reappeared in another corner, casting the same spell.

In the eyes of the three people, the professor seemed to be transformed into three in an instant, casting three spells at the same time.

"Bang!"

"Bang!"

"Bang!"

The three big black dogs were cursed and fell down instantly.

Under the invisibility cloak, they were stunned.

"Oh my God, what kind of magic is this!" Ron opened his mouth wide, and recalled the scene just now in his mind.

In the black smoke, the professor's stern face appeared with a red light, and in the blink of an eye, it appeared in another place. This speed was too fast to dodge or resist.

Harry also widened his eyes.

In the center of the open space, Felix, who had just released magic, shook his head, but it still didn't work. He deviated half a meter.

This was only two jumps. If he jumped eight or ten times, would he be hit by his own spell?

The reason why Felix came out was actually to perfect his Trinity raid tactics. At his age, he named this tactic "Instant Kill" technique:

the principle is very simple, Trinity, that is, three magics are used at the same time, perfectly integrated, and 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 "Thinking Acceleration" to maintain one's own balance and reaction ability.

When they are combined, Felix can release spells from more than a dozen different positions in an instant, forming a gorgeous cross-line of vitality, thus achieving the terrifying effect of one person being a team.

The principle is indeed simple, but the road is extremely difficult.

The difference lies in how to improve his own reaction ability and how to keep the body balance in an instant.

At the beginning of the school year, he developed the prototype of this magic, or a branch technique - "Thinking Hut", but it can only be used as a teaching technique. Now more than two months have passed, and he has not been idle during this time.

While Hermione was practicing runes in the Thinking Hut, he was thinking about how to apply it to combat in the Thinking Hut.

Fortunately, he has gained a lot of experience recently.

This is why he went deep into the Forbidden Forest for several days in a row - to avoid the ubiquitous anti-Apparition spells in Hogwarts Castle!

"Two jumps, barely acceptable." Felix was quite satisfied, after all, it will be improved in the future.

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

"Come out."
