"Is that really good...... Ahh ”

Ricardo added another invisibility charm to himself, and walked to the door of the fourth-floor corridor in a trembling manner, with a note in Dumbledore asking him to help Harry's trio through the level.

"I guessed right! Dumbledore wants me to clear their way! What else to say just in case! ”

He opened the door with a little pathos as a tool man, and confronted a giant dog.

The dog was so big that it filled all the space from ceiling to floor. It had three heads, three pairs of dripping and turning vicious eyes, three noses twitching and trembling in their direction, and three drooling mouths that hung from the yellowed dog's teeth like slimy ropes.

It stood motionless, all six eyes staring at them.

"Hey, big guy, the sun is setting...... Depend on! ”

Ricardo tried to lull the three-headed dog to sleep in the same tone that Black Widow had coaxed the Hulk, but the three-headed dog rushed up with a loud roar, his eyes bloodshot red, and he seemed to have a tendency to go berserk.

"Hey big guy, how do I think you're a bit the same as the fire dragon I solved a few months ago......"

Ricardo dodged the attack, "split" and stabbed out, pointing directly at the eye of the middle head of the three-headed dog, the three-headed dog dodged, and the left head bit Ricardo's shoulder, he dodged in embarrassment, and the three-headed dog immediately stretched out his claws and grabbed Ricardo;

Ricardo rolled on the spot, and quickly jumped up, "fainted" pointed directly at the right throat of the three-headed dog, the three-headed dog wanted to repeat the old trick, the middle head bit Ricardo, he turned his head and took a deep breath, and actually spit out a fireball, wrapping the middle head of the three-headed dog, and it took a long time to struggle out.

Ricardo's move remained the same, pointing directly at the right throat of the three-headed dog, but the three-headed dog roared, the throat became thicker, and his magic spell was shot to no avail, and at this time, the right paw of the three-headed dog had grasped Flot's body, as if it was about to be disemboweled.

"Ricardo Silva is flying!"

Just then, the door suddenly opened, and Kassandra walked in and rescued Ricardo. Then, she raised her wand and uttered several dark magic spells, and several scars appeared on the three-headed dog's body. Ricardo also reacted quickly, and one rolled over and continued to wrestle with the three-headed dog.

"You know for sure how to subdue the three-headed dog!" Kassandra whispered as she brushed shoulders with Ricardo.

"That man drove the three-headed dog crazy." Ricardo also explained in a low voice, using a spell to interfere with the three-headed dog's attack.

"Okay. Unexpectedly, the famous dragon slayer Ricardo couldn't beat a three-headed dog. Professor Snape immediately regained his poisonous tongue nature.

"I'm going to save some mana, and there's going to be a big battle later."

Ricardo didn't have the heart to talk to Kassandra now, so he took advantage of Kassandra's release of Kukulkan to attract the attention of the three-headed dog in the front, and another stick came east, and the blade slashed at the waist of the three-headed dog without a shadow.

It is said that canines are copper-headed and iron-boned tofu waists, and the waist is the biggest weakness of dogs, and the three-headed dog is naturally no exception, it howls and rushes towards Ricardo, Kukulkan takes the opportunity to bite the back of the three-headed dog somewhere, the three-headed dog is in pain, and the tail is flicked, and there is actually a dragon swinging tail, throwing Kukulkan against the wall, and viciously pounced on Kassandra.

"Burn!"

At this time, Ricardo couldn't care less about saving, a fierce fire spell shot out, smashing the three-headed dog and screaming, and then being hit by Kassandra's weather spell lightning strike, finally unable to bear it, fainted on the ground.

Before they could catch their breath, there was a commotion outside, and Ricardo immediately opened the trapdoor and looked at Kassandra:

“you jump…… No, this can't be skinned to students, go down or stealth? ”

Kassandra ran to Ricardo's side, and the two of them jumped down together.

"Yugadim Leviosa! *2”

For a while, Ricardo thought he had crossed over again, and now the third prince of Loki, the kingdom of the gods, Asgard, was being forcibly tortured by Doctor Strange for half an hour. He couldn't stop falling down, falling, falling, and .........

"Plop!"

With a single impact, Ricardo and Kassandra freefell for nearly twenty meters, finally landing on solid ground.

"Looks like I guessed right," Ricciardo held out his hand and grabbed Kassandra, "Dean Sprout's devil's net was dismantled by Voldemort. But you gave me a levitation charm first, which really surprised me. ”

"Don't be pretentious," Kassandra's voice grim, "I just don't want to be charged with the professor's murder." Besides, Kukulkan will ...... Hey? What about Kukulkan? ”

Ricardo looked up at the stamp-sized hole and guessed, "It'...... Maybe it's on it, and it's used as a gatekeeper. ”

“……”

Kassandra pursed her lips and didn't speak, took out the card, whistled, and Kukulkan, still covered in thunder and lightning, came out of the hole and pounced on her master.

"Don't come here!" Kassandra's tone was angry, "You still have thunder and lightning on you. ”

The little feathered serpent suddenly stopped, and shrunk into a ball in the air in a sullen manner.

Ricardo cast an invisibility and silence spell on her and herself, and it was only when her lightning was put away that Kassandra took back the little Feathered Serpent.

"You don't seem surprised at all by my involvement." Kassandra asked in a whisper.

"Didn't you say so much before just to probe me?" Ricardo waved his wand and cast a levitation charm on the three people who fell, "I don't care what you want to do, but if you really want to fight, don't blame me for throwing you out of the battlefield." ”

By this time Harry, Hermione, and the redhead had reached the surface, so they stopped talking and followed the trio.

They walked down the hallway. It was quiet, except for the sound of the trio's footsteps, except for the sound of water droplets dripping down the walls.

There seemed to be a light ahead, as if there was a soft rustling and clanging sound—like the flapping of wings.

Finally, they made it to the end of the hallway. In front of it is a brightly lit room surmounted by a high vault-shaped ceiling. Countless small birds, as brilliant as jewels, flapped their wings and flew around the room, and there was a heavy wooden door opposite the room.

The trio walked over to the door and found that it wouldn't open at all.

"We're looking for a big antique key. It may be silver and shaped like a doorknob. ”

The red-haired boy said.

So, they got on a corner broomstick and began a chase, which Ricardo watched with interest, even though he was not interested in Quidditch.

Kassandra next to her yawned, but luckily they didn't hear it.

When they opened the door and left, Kassandra walked to the door a little drowsily.

"Wait a minute."

Ricardo stopped Kassandra and handed her a broomstick.

"Let's go to the theater on a broomstick, I'm sure it will save us a lot of time. It's a pity that Professor Flitwick's trick wasn't discovered by Miss Granger. ”
