Before Filch could reach the library, Rov had sneaked out with Hermione and the others.

The movement of the sniffers catching silverfish was so loud that the professors on several floors were probably woken up.

The stairs must not be able to be walked, and Rov led the group to a wall on the second floor, where a portrait of Devonte Simplin hung there.

Devonte Simplin is a wizarding comedian who eats the whole poison tentacle during a bet, and although he does not die, his skin turns purple and becomes a small purple sweet potato.

Rove tapped on the portrait and whispered the command, "Navel Eye!" ”

Purple sweet potato spirit Devonte Simplin opened the portrait, revealing a small secret passage, and Rove was the first to get into it.

The three of them followed, and Hermione looked at the long and narrow space, very surprised, and dumbfounded:

"I've been here several times, and I never knew there was a secret passage."

"Since it's a secret passage, don't you know if it's normal?"

Rove stood in the secret passage, looking at the map at the light of the fireflies, and he had already made plans to deal with the current situation.

He had several routes to get Hermione and Shirley back to their respective common rooms safely without taking the stairs.

In the middle of the night, you can't help but send the two girls out to play a tense and exciting night tour, and let them take the stairs by themselves, and then be caught by the professors, right?

That's too much of a beast.

Even his grandfather, Scamander, couldn't do such a straight man's thing.

Hermione continued, "How did you know there was a secret passage?" ”

The little girl has a strong thirst for knowledge, or rather, her curiosity about Rove is endless, and she always wants to find out all his secrets.

Rov raised the map in his hand and whispered, "This is a gift from Filch to Lady Loris, who has summarized some of the patterns of shortcuts and stairs in the castle. ”

"Would Filch do anything like that?" Hermione snorted in surprise, she narrowed her eyes, looked at the map out of the corner of her eye, and said, "Didn't they all say that he was bad with his students?" ”

Rove raised his head, smiled kindly, and patiently explained:

"Don't let one's appearance and other people's words affect your judgment, that's the most important thing."

The boy added:

"Just like me, many people misunderstand me, but in fact, I am a good boy who is not good at words, loyal and sincere, and has a bit of social phobia......"

"If you don't add the latter sentence, it may be more convincing." Shirley clasped her hands to her chest and gently raised her willow eyebrows.

Hermione couldn't help but smile and nodded vigorously.

Rove gave Shirley a blank look, even you have learned from Hermione, and there was even more threat in his eyes:

Little assistant, subordinates can't be bosses!

Be careful of deducting your salary this month!!

Hearing that there was no movement outside, Rove set off again, making his way through several secret passages to the fourth floor.

As he passed through the restricted area, Rov glanced at the hallway not far away, which Dumbledore had strictly forbidden to enter, as if his attention had been drawn.

"It's off-limits, don't even think about it." Hermione saw the boy's thoughts at a glance, and she warned, "I won't let you in." ”

"I'll just take a look, and I won't go in......" Rove walked unconsciously towards that side.

Rove really didn't go in, it's not that he didn't want to, it's that the entrance is too small...... Stuck.

Literally stuck.

From a distance, Rove saw the smallest head of the three-headed dog, Louvie, who seemed to want to get out of the door, but was stuck in the entrance, unable to get in and out, and let out a whining sound.

As Rove walked over, the three-headed dog immediately let out a threatening sound and sprayed saliva all over the ground, but it was useless, and its head was stuck.

The three-headed dog, which was originally fierce and could not be approached by anyone, suddenly became weak and bullied.

Even Neville, the least daring, dared to take the dog's head with his hands after the initial fear.

What is this card washing machine plot? Or Rove's favorite series.

Rove stretched out his hand and flicked Lore's black nose, and there was a sudden "ding" sound in his brain.

[An adult three-headed dog was detected, triggering side quest 1:]

Help the three-headed dog's stuck head get out of trouble and reward magic:

【Hyperactivity】

Drain your body mana, activate your bodily functions, greatly increase your speed, strength and mental focus, and maintain a state of euphoria.

【Side Mission 2】

Help the three-headed dog clean his teeth and reward magic:

【Beast's Mouth】

Your teeth can secrete toxic substances, and the creatures you bite will have a hard time healing wounds.

【Side Quest 3】

Complete 100% domestication of the Three-Headed Dog, rewarding Magic:

【Three-Headed Dog Seal】

You can grow three heads.

(Mission not completed)]

Rove glanced at the system, which was the most grassy reward he had ever seen, if he could grow three organs, such as **...... He's okay with that.

But three heads are enough.

As for the first two rewards, they are not bad, especially the first [Hyperactive], which is simply a stimulant effect.

In that case......

"We've got to help it get its head out." Rove said.

"But how?" Neville asked.

Rove glanced at the wall and said, "Blow up this wall......"

"Well, good offer." Hermione snorted, "We're going to be fired tomorrow for destroying the castle." ”

"It's really not okay to be so violent." Rove whispered, "We can shrink the three-headed dog's body so that its head can be retracted." ”

"Does the Shrinking Charm work?" Shirley asked.

"With the magic resistance of the three-headed dog's fur, let's use the shrinking spell together, and release it overnight, maybe shrink a little." Rove shook his head.

"What then?"

The young man dug in the black leather box, and after a while, he took out a bottle of bright and dazzling green potion and said:

"It's a shrinking potion that allows the drinker's body to shrink or transform into a more youthful form."

The effect of the shrinking potion is very powerful, it only takes a little bit to work, and it is also the most common way to capture fire dragons in Romania.

"Open your mouth and drink the medicine!"

It was impossible for Rove to pour potion into Louwi's mouth, after all, it only ate the food Hagrid gave, but now that its head was stuck, it couldn't help it.

Rove tapped the Adam's apple on Lou Wei's nose, and the moment the latter opened his mouth involuntarily, he shoved a bottle of potion into it, and several people pressed it down together.

Lu Wei struggled all over, but his body began to shrink, and after only a few minutes, he changed from an adult giant dog several meters tall to a palm-sized puppy form.

Rove walked into the room, and Lowe pounced, vicious dogs tearing at his trouser legs.

Throwing away the big juvenile three-headed dog, without the slightest threat, the young man picked up Lu Wei along the back of his neck, pumped its buttocks, and threw it into his black suitcase.

After the task of cleaning the teeth, send it back in two days.

It should be fine, right?

……

……

Standing at the door of the Potions office, staring at Harry and Ron, Professor McGonagall was so angry for the first time, she suppressed her anger and said:

"Mr. Filch said you two went to the prize showroom on the third floor to wreak havoc, and after being discovered, you ran to the restricted area on the fourth floor, and Malfoy stopped you, and you two beat him?

Explain it yourself. ”

"I ......"

"We ......"

Harry and Ron found that they really had nothing to explain, except that they didn't go to the showroom to destroy it.

Well, it might be worse to say that you are going to a duel yourself, after all, this is the nature of a fight.

Snape smiled comfortably as he said softly:

"Professor McGonagall, I don't know if you recall anything, but Potter's behavior reminds me of his father...... It's exactly the same, isn't it? ”

Harry looked up at Snape, who stared into his eyes and said coldly, "Glaring at the professor, Gryffindor deducts two points." ”

"I'm outraged," Professor McGonagall said, "you're both going to be locked up...... Gryffindor was deducted another fifty points. ”

"Fifty points will be deducted for each person!" Professor McGonagall said coldly.

"Professor...... I beg you ......"

"You can't ......"

"Now that you are pleading, why did you go earlier?" Professor McGonagall said indifferently, "Alright, let's all go back to the common room, I don't want to see you two again tonight, I've never been so ashamed of Gryffindor students as I am now." ”

……

……

4th Floor Restricted Area,

Dumbledore, who was wearing pajamas, pushed his half-moon glasses and looked at the empty cabin, a little embarrassed.

How was he supposed to tell Hagrid.

His puppy ......

Lost.

……

……

(ps The Shrinkage Potion, which had been brewed since Harry's third-year students, wasn't a rare potion.)

Snape also fed the potion made by Neville to Leif at the end of class, and with Hermione's help, Leif was able to turn back into a tadpole after drinking it.

Secondly, the effect of the shrinking potion is twofold: one is to simply shrink the body, and the other is to return to childhood.

As for when and which effect will take effect, this original book does not say, I can only assume that it is related to measurement.

Rowling also added the setting to the official:

Bucky accidentally spilled a little shrinking potion on the lawn outside the house, and the lamb was reduced to the size of a fluffy mouse.

He also gave the Tertius brothers, who shrunk to the size of beetles and hid under the cupboard for days to prevent their cats from picking them up and eating them.

So shrinking potions work for Luwe, that's for sure, many potions are powerful and have wonderful uses. ）
