"You're a little unqualified, did you get the position of Defence Against the Dark Arts professor through the back door!" Roger glanced meaningfully at Lupin's ass, "I heard that Dumbledore recruited you at the time..."

Lupin smiled bitterly, not hearing the double meaning of the words: "So I'm a 'former' professor now... And, if it weren't for the Dementors, who would have drunk so many Joy Potions?"

Roger made a 'this is also true' expression, felt his emotions for a moment, and said, "But it finally worked, didn't it? I didn't feel very sad..."

Lupin also moved his body, and then said helplessly: "I think it's right... My whole body hurts and I feel cold, and I can't wait to find a rope to hang myself..."

"Your embarrassing desire to die, it has nothing to do with the Dementors... Don't lie to people at every turn. Roger teased with a smile.

"But I don't dare to say anything, the Xin potion has worked, and as for the side effects it brings...", he glanced at the professor's arm, "Compared to the consequences of kneeling directly when you meet a dementor who is looking at you, it is still easy to bear." ”

Professor Lupin shook his head with a wry smile, and his wand tapped at the plank on the side of the ship: "Anyway, since the potion has worked, let's get to the island quickly... I'm not sure how long the Elixir will be able to hold off. ”

There is another point he didn't say, even if the Dementors basically don't have any physical attack ability, but even if the Dementors with hundreds or thousands of them are rammed, it is a question whether the wooden ship can hold up.

The ships were moving laterally again, after all, they were now only able to pinpoint the position of Azkaban from the side guns. Although it was a bit intimidating to huddle in the cabin and rely on the Elixir of Joy to fend off the Dementors, they didn't come to destroy these difficult evil monsters, but to save people.

However, Lupin was somewhat grateful to the Dementors for coming in time, after all, just now, Roger had already decided to level the prison... He didn't think that the collapse of the entire building would have saved Bellatrix Lestrange's life.

With the ship under the control of the Professor, Roger picked up the barrel again and poured gunpowder into the cannon.

"Hey, what are you doing!!!" Lupin asked, interrupting the boy's movements.

"Rest assured... I'm sober now and know how much to put in. Roger said soothingly, "We'll have to figure out a few ways for ourselves, don't we? ”

As he spoke, the creature stuffed the cannonball in, compacted the gunpowder, and poked his wand...."Boom!"

The sound was much smaller than the one that had just exploded, but it still violently dispersed the two Dementors in their way, and castrated a hole in the blue-gray wall.

Roger looked at the cannon that was emitting green smoke outward, and said with some unfinished feelings: "Although I was a little stupid to do that thing just now, I have to admit that it was still very enjoyable... Why don't we try two more shots?"

"No! The professor said firmly, "I'm surprised that it can kill Dementors, though. ”

"When magic doesn't work, you have to try to destroy the enemy with your fists... This often pays off. "Roger pretended to be nonsense. In addition to magic, he can only use his fists.

And the thing didn't pay any attention to Professor Lupin's words, and still poured a large amount of gunpowder into the barrel.

"Hey!wait!You're pouring too much!" Lupin saw that something was wrong and stopped him.

"Well, almost—" Roger tossed the barrel again, pouring more gunpowder down a handful before stopping.

At this time, the dementors of the same kind seemed to be enraged, and no longer just comfortably absorbing the large amount of happiness emitted by the two people, they began to gather towards the two gaps on the side of the ship, and at a glance there were at least hundred, and the black pressure squeezed into a ball and slid over the sea, like a ghost-chasing demon trying to drag the two into the abyss of hell from the muzzle of the cannon.

Lupin waved his arms quickly and powerfully, "Divine Guard!"

But only a silver ray of light came out of his wand, swaying like a mist in front of him... But with the glimmer of this formless Patronus, the Dementor was kept out of the cabin from the side guns. It can't pass through the silvery mist that Lupin emitted.

"Whose wand is it?, I'm not comfortable with it!" exclaimed Lupin, trying his best to maintain the silver mist. He couldn't care about the moving ships anymore.

"Voldemort's..." Roger pushed the cannon with the cannonball in front of him from the second side of the cannon in front of him, and slammed a Dementor who had already poked in half of his body in place. Facing so unsuspecting against a large number of Dementors, Roger felt the strange coldness seep through his internal organs.

"Eat the Armstrong Boom T After all, Professor Lupin has just taught us by example that it is not advisable to ignite a fire directly with a wand.

"Boooom!!" The familiar loud explosion sounded from the cabin again, and Professor Lupin, whose eardrums had been damaged twice, couldn't maintain the silver mist of the Patronus Charm, and covered his ears with a muffled snort.

But Roger, who had been mentally prepared for a long time, immediately poked his head out of the muzzle of the cannon to watch the effect of the attack, and he didn't feel the pain, and directly ignored the scattered fragments of the rifled artillery.

The excess amount of gunpowder gave the solid iron cannonballs unparalleled power, but the quasi-head couldn't care too much...

The black-pressed horde of Dementors was as if a black drawing had been erased, and a blank diagonal line had been drawn from it. Finally hit the middle of Azkaban, opening a huge hole.

The Dementors stopped, right next to Roger's bodies leaning out of the window, and he could feel them watching him, hearing their gurgling breathing, and the pleasure of a cannon opening a way through the midst of the enemy was quickly vanishing.

While the Dementors were observing him, Roger was also observing the Dementors at real close range for the first time, and the coolness disappeared, and all that was left was unpleasant...

It was a humanoid monster that looked like a shabby black cloak, tall but emaciated, with jagged ribs visible from its cloak body. Its face was completely hidden under the hood, but a hand came out of the cloak, which shimmered, gray, thin...
