By the time the smoke cleared, the iron cannon had already been pushed up to the other side of the cabin by the recoil of the explosion, the thick barrel had turned into an iron horn, and the excess gunpowder had blown up the antique weapon.

The wooden hull was full of holes made of broken iron, and Lupin's stockpiles were so black that the wizard's robes, which were already patched, were torn out even more.

His body bones were obviously no better than his clothes, the arm that lit the fire was directly drenched in blood, the bones on his wrists and the back of his hand were exposed, and his thighs and body were also cut by fragments, and now they were slowly bleeding outward.

"Cool~" Roger, who was also covered in black smoke, stood by the muzzle of the cannon and stared at his eyes and smiled wantonly, his exposed teeth looked particularly white against the background of his black face.

Although it was not him who ignited the fire, he was much worse than Lupin's luck, and the lower abdomen on the right side was directly inserted into it by a sharp patch, and it was visually estimated that at least the waist needed to be replaced, not to mention the rest of the small wounds.

After giving a thumbs up to Professor Lupin, who was dressed in a tragic appearance, the creature looked at Azkaban with the greatly enlarged port muzzle, not feeling that it had any bad effect on the Professor's injuries.

"Hah! hit!" Roger laughed excitedly and beckoned to Professor Lupin, "Come and see! we've made a big hole in that frustrated building!!"

However, Lupin didn't move, just stood in place and held up his arm that had been blown into flesh and bones, and said with a smile and frustration: "Look... My wand! it's broken, and a Muggle's wand is stronger than a wizard's..."

As he spoke, the professor turned his head to look at the cannon that had been blown up in the back, and then the smile on his face won the victory, and he said cheerfully, "But Muggle wands are not better!haha..."

"Don't worry about that, there are several more in the cabin, we need to have a few more shots!!" Roger saw Lupin looking back at the exploding cannon, grinned and pulled the professor to another side gun port not far away, and quickly untied the fixed cannon.

"How about we say we just blew up Azkaban? I think that's a good idea!!" the thing shouted excitedly.

Lupin's hand, who was pulled away, finally looked at his student, tilted his head and said puzzledly: "Uh... Roger, what are you doing? Why don't you just open your mouth and not speak?"

This kind of close-range explosion directly blew up the two people into temporary deafness, Roger was okay, this small injury was no longer affected in the blink of an eye, but Professor Lupin was miserable, and his ears were left with a little blood, but it was not conspicuous on his blackened face.

Hearing this, Roger understood what was going on, and raised his wand to point at Lupin: "I often beat people with magic, but I haven't repaired people's eardrums... But what's the difference? It's all magic. You're right, Professor?"

"What are you pointing your wand at me, like me?" Lupin stared at the wand on the tip of his nose, still joking inappropriately.

"Hurry up and recover!" The light of the spell hit the professor's head, and he shivered twice, slowly raised his head sluggishly, and opened his mouth wide in pain: "Ah... Yes... Ahh

Roger dodged the spit that sprayed at him, stared at Professor Lupin for a moment as he sneezed, shrugged his shoulders irresponsibly, and turned to carry the powder keg.

"How much do you think we're going to put this time? Anyway, there are more guns here and less gunpowder, and the rest is also a decoration~" He put up the new cannon and said as he poured gunpowder into it.

Professor Lupin, who was about to spew his brain out, walked to the muzzle of the cannon while sneezing, looked out, and said indistinctly: "Look at this power, I want to... If you want to destroy Azkaban, at least... Ah Qiu!!!Raise a hundred... Ah Qiu!

Anyway, Lupin could hear the sound, and the little sneeze didn't have to care.

Roger shook the powder keg, these stocks could not even reach ten times, let alone a hundred times. The expression on the face of this thing was closed, and before his brows could be furrowed, he immediately became frowning again.

"It doesn't take a hundred times!Look what this is~" He snapped his fingers, took out the old parchment that Dumbledore had given him from his pocket, and exclaimed excitedly: "Azkaban's architectural drawing! As long as you find the load-bearing wall, it will collapse in a few shots!" haha..."

"Load-bearing wall...?" Professor Lupin said he didn't know what it was, and that wizarding buildings didn't need it at all... And he didn't delve into it with curiosity, because something more important caught his attention.

"You say... Have we forgotten something?" said Lupin slowly, not even sneezing again.

"Forget what—" Roger was barely halfway through his sentence when the already chilling temperature around him suddenly reached a new low, and a long, slow gasp sounded quietly outside the cabin, shivering, as if trying to suck in something other than air from the surroundings.

Both of them felt a chill rush over their bodies. The chill penetrated through his skin, cold to his brain and chest, and Roger felt something in his body be robbed of it by the sound of gasping... The warm feeling brought by the elixir immediately weakened, and the excited brain also calmed down for a while.

Lupin carefully picked up his injured hand with some trembling care, gritting his teeth and gasping for air.

Roger blinked, lowered his head and pulled out the piece of iron from his stomach and threw it to the ground, a tall black shadow fluttering past the muzzle of the cannon.

"It's the Dementors! they've already discovered us!" Roger was startled, and quickly pulled out his second wand from his waist and threw it to Professor Lupin, "Take this, my Patronus Charm is not home yet!"

He remembered that Lupin's wand had been blown off.

The professor took his wand in severe pain, poked his arm to heal the wound, and then stared warily at the other open muzzle.

However, the Dementors didn't seem to have any intention of rushing in directly, floating around outside the cabin, inhaling one after another.

"I didn't expect this effect from drinking too much of the Elixir of Joy..."Even though the Dementors had already surrounded the place, Lupin still muttered to himself about the performance he had just done.

"yes, I didn't expect it to have a mental reduction effect... By the way, you, a former professor, don't even know this?" Roger said with a helpless expression rubbing his face with one hand.
