After confirming that it was safe, Rosie closed the map and walked out of the prize room with the three of them.

After walking along the corridor to the north for about half a minute, the group finally came to the door of a locked room outside the corridor on the fourth floor.

From what I've seen before, this is the way to get to Harry's location.

"Strange, how can this place be locked? Didn't Harry, they get in from here? ”

Rosie was puzzled, but the wand in his hand pointed at the steel lock without hesitation:

"Alaho Cave Open!"

The iron lock opened.

"I'll fight the outpost."

With that, Ah Bai stepped forward and pushed the door open.

As the heavy wooden door creaked open, a low, frantic barking was immediately heard.

"Quick! Go inside and close the door, lest the barking of the dog attract others. ”

After Ah Bai finished speaking, he took the lead in getting through the crack in the door that could only be passed sideways.

Seeing this, the three of Rossi could only follow him into the door.

As soon as he entered the door, he saw Ah Bai blocking the front as if he were facing a great enemy, and the wand in his hand was pointed straight ahead.

In front of the four, a three-headed vicious dog that stood up almost to the ceiling was staring at them.

"Three-headed dog, level: 81, HP: ? /？ ”

His territory was invaded by others one after another, and the angry three-headed dog finally turned completely red-eyed.

For a moment, it just wanted to rush over and bite the strangers who had intruded into its territory to pieces, and it didn't care about any promise not to hurt others.

"Protect them all!"

Ah Bai immediately placed a defensive charm in front of him, trying to defend himself against the three-headed dog's attack.

Seeing the three-headed dog rushing towards him and the others, the feeling of oppression brought by the huge size made Rosie a little frightened.

"The grade difference is too much! Don't try to resist it with magic, spread out! With a broomstick! ”

As he spoke, Rosie wrapped his left hand around Jiang Jing's waist, and pointed his wand in his right hand in the direction of the three-headed dog:

"Faint!"

However, although the spell entered the body of the three-headed dog without accident, the three-headed dog did not pause for even a second.

"Click!"

The barrier that had been protected by all of them instantly turned into fragments of magic in the sky, and the sharp claws of the three-headed dog scratched towards the four of them with the sound of whistling wind.

"Quick! Hurry up! ”

Seeing the sharp claws glowing with cold light coming towards him, Luo Xi's left hand on Jiang Jing's stomach couldn't help but pinch it hard.

"Lift, lift!"

At the same time as the spell was recited, Jiang Jing reflexively hugged her slender waist, and in her stunned eyes, the two of them rose from the ground like rockets.

Just as the two were about to hit the ceiling, Jiang Jing's body slammed into the horizon, and the wand in his right hand had been replaced by a golden broom at some point.

"Fast enough?"

Hearing his playful tone, Rosie couldn't help but glance at him.

"I remember that the weakness of the three-headed dog seemed to be music...... Well, there's a harp near that trapdoor on the ground, and we can use it as well......"

Thinking of this, Rosie immediately shouted loudly to Erin, who was hiding on the other side without a shadow:

"Irene! ...... with that harp."

Before he could finish speaking, the three-headed dog that missed the blow roared even more frantically.

"Whew-"

The three foul-smelling mouths opened wide at the same time, and in the next second, an overwhelming blizzard raged through the room.

“-198”

“-134”

“-88”

……

"How can these three-headed dogs still cast magic ???"

Seeing that his blood volume was declining, Rosie immediately looked at Jiang Jing in fright, and the wand in his hand shook rapidly at the same time.

"Armor protection!" X3

"Protect them all!" X3

"Quick Treatment!"

Several people immediately used magic to protect themselves, and in order to prevent the lower-level Jiang Jing from being seconded, Erin even used healing magic on him.

But Rao is like this, when the blizzard stops, the blood of the four people is still bottoming out.

"Sissy—"

Erin clasped her hands to her lips and shouted loudly, "What did you just say? ”

"That harp! With that harp! ”

Rosie replied loudly, reaching out to point out the location of the harp to the other party, but was suddenly dumbfounded.

But the harp had been torn apart by the three-headed dog's blizzard.

"What harp?!"

Erin asked again.

As he spoke, Jiang Jing had already flown to Erin's side with Rosie.

"It's nothing, you can sing it a song!"

"Huh?"

Now it was Erin's turn to be dumbfounded, "Do you want to hear what you're talking about?" ”

"The weakness of these three-headed dogs is music!"

Rossi explained.

At this moment, the three heads of the three-headed dog turned, and the original side head suddenly changed to the middle, and then, its front paws slapped heavily on the ground.

"Boom!"

Ice picks rose one after another like hills, stretching towards the four of them.

Rosie sat behind Jiang Jing, watching him skillfully dodge left and right on a broomstick, calmly shuttling between the crevices of ice picks, and couldn't help but admire his flying talent.

"That's amazing, when will I be able to fly so well. No, no, now is not the time to think about that. ”

"If the weakness is music, I don't know if I can sing......

Rosie was thinking about it, but she heard Erin, who was not far away, suddenly open her voice and sang loudly:

"Dada, da! Da! ”

Erin's voice is clear and pure, even if she just hums a song without lyrics, but the emotions in it are still intoxicating.

As the melodies of the song drifted through the room, the chasing icicles immediately stopped.

I saw that the three big heads of the three-headed dog kept dozing little by little, and the six pairs of eyelids were also drooping down, and they fell into a deep sleep in a blink of an eye.

"Don't stop!"

Rosie jumped lightly, jumped off Jiang Jing's broomstick, and slowly leaned towards the sleeping three-headed dog with his eyes closed.

The trapdoor that led to the space between the floors was next to its three heads.

Rossi, who didn't dare to breathe, looked at the three-headed dog vigilantly, endured the smell of its body, and gently pulled the pull tab on the door.

In an instant, the trapdoor leading to the bottom opened.

It was pitch black below, and it was impossible to see how much space it had at all.

Rosie tried to light her wand with a glowing charm, but as soon as the light penetrated under the trapdoor, it was immediately engulfed in darkness and did not have the effect of illuminating it.

Seeing this situation, Ah Bai couldn't help but be amazed.

Jiang Jing groaned and judged:

"It looks like there's magic applied down there, and we'll have to jump in to see its environment."

"Well, let's go down quickly, although Erin doesn't need to breathe, but if she continues to sing like this, she won't be able to stand it."

As he spoke, Rosie took out her broomstick and jumped down.

As she fell, the cold, moist air rushed to her face.

Seeing himself through the door, Rosie immediately turned around and rode a broomstick in the air.

"Fluorescent flicker!"

A soft glow instantly illuminates the surroundings.

She was in a bottomless passage of a cube, surrounded by damp stone walls.

"Isn't this between the third and fourth floors? How deep is it? ”

Ah Bai stopped next to Rossi and said suspiciously.

Jiang Jingfei, who jumped behind him, came over and said, "It should be some kind of magic that can expand the space." ”

"Whew, Sissy, you're so good, you can judge from a harp that the weakness of the three-headed dog is music, you really deserve to be a detective!"

"Why!"

Rosie brushed her hair embarrassedly: Can I say that I know the plot?

Changed the topic and said: "Erin, it's still your credit, you sing so well, you can become a star idol!" ”

"Hey, is there?"

……

"You two don't blow each other, pay attention to the following, it seems that something is jumping up."

Hearing Jiang Jing's reminder, Rosie immediately looked down.

With the glowing light of the Glowing Spell, she immediately saw countless dark green plants surging upwards in clusters of each other.
