Professor of Pharmacy at Hogwarts

"Hey! Alexis-"

Christie chased after him and wanted to say something else. The iron door had been closed by Alexis, and then there was a banging sound, and the iron door was reinforced by Alexis.

Alexis fixed the iron door and turned around. At this time, the outside was densely packed with Dementors, and all the Dementors in Azkaban were rushing towards him.

Alexis squeezed the wand, put it back into his pocket, and took out an elder wand from his arms. This wand looked very old, and the wand was even slightly bent.

The moment he held the elder wand, scenes from the past flashed through Alexis's mind: the salty sea breeze, the golden pumpkin patch, the windmill, the ugly toys, the clumsy stone castle...

"Calling God - Guard"

Alexis opened her eyes and shouted loudly.

Wisps of silver-white starlight emerged from the tip of the staff. They circled and rose halfway up to meet the dementors.

Unlike other people's, these starlights collapse at the touch of a button, and just like their appearance, they look illusory.

"damn it!"

Alexis cursed and gave up hope.

He raised his head and looked at the central tower of Azkaban.

The wand in his hand was slowly waving as if unconsciously, and there was a snapping sound all around.

The next moment, just as the Dementors swarmed up, he disappeared and appeared at the top of the tower.

The dementors jumped away, lingered at the door for a moment, then all turned and rushed toward the tower.

Alexis climbed to the top, looked around, and after silently calculating in his mind, he raised the elder wand again.

"Fire Escape--Protection"

The faint blue flame turned into a fire dragon, flew out from the tip of the wand, swirled in the air, and danced wildly. The fire dragon spread quickly and enveloped the tower at his feet.

Teng——

After the fire dragons merged from both ends, blue flames suddenly rose up.

Alexis raised her wand high and looked through the flames into the distance.

Above the sea, in the pitch-black night, a large black dot was flying towards this direction.

The black spot was quickly obscured by the dementors, and Alexis' field of vision was completely occupied by the dementors.

The dementors densely surrounded Alexis.

The feeling was like reaching out of an ice cellar. Alexis felt that her limbs had been frozen and the blood in her veins had stopped flowing.

A Dementor approached Alexis, almost face to face with him.

Dementors have no facial features, they are just a mass of black smoke.

The dementor stretched out its smoke-formed claw and pressed it against Alexis's left cheek.

Wisps of silvery white light flashed from Alexis's facial features.

The dementor made a sucking gesture, but those silver bands of light only flickered once and then disappeared.

The Dementor lowered its claws and retreated back into the group of its companions.

They still did not let go of Alexis, but kept spinning and flying around Alexis, like a group of hunting lions, looking for a place to bite.

Finally, the Dementors decided, and its body paused in the air for a moment before rushing towards Alexis.

whoosh-

It seemed to be the sound of wind, perhaps mixed with sharp and high-pitched screams, but these were only for a moment, and then the whole world fell silent.

Alexis only felt that her body had become stiff. Strangely, the cold feeling disappeared, and the uncomfortable sound, like fingernails scratching the glass, also disappeared.

The fire escape guard disappeared, and the surroundings were dark.

He wanted to see his wand. Had he interrupted the spell?

Valley</span>The wand is also missing.

His arms, hands, torso, legs, his entire body seemed to be missing.

……

In the prison area.

Lupine and Christie sandwiched Harry on the left and right. There were a dozen fish that slipped through the net outside them, and the two of them took care of them in a few seconds.

"Fire Escape Bodyguard!"

Christie exclaimed when she saw the faint blue flames outside through the gap.

Ever since Grindelwald disappeared, Fire Escape has almost become Alexis's signature spell. There are not many people in the world who can use Fire Escape to protect themselves. Those who can use it so vividly and are still active outside are the only ones who can use it so vividly. There was only one Alexis.

The two looked at the open iron door - the one leading to the prison area.

Although Harry didn't know what was happening, he could feel that both Christie and Lupine were worried.

At this time, he regretted a little, regretting that he had followed him willfully.

If he wasn't here, maybe Christie and Lupine would have followed Snape and Black to find someone, maybe they would have found the person Alexis mentioned.

Maybe they have already begun to retreat!

Without him, Alexis wouldn't have to face such a large group of dementors alone, right?

……

In the prison area.

Snape and Black have already passed the gate leading to the depths. Their cooperation is full of loopholes. Fortunately, they are strong. After long-term imprisonment, the prisoners here have almost become Alzheimer's. So far, they can cope with it.

So far, the two of them still don't understand why their previous plan was to guard Azkaban against possible Death Eater invasion, but now it has become a search for someone, but time is running out, and they choose to believe Alexi Si's judgment.

They also saw the fire escape guard outside.

Alexis doesn't know the Patronus Charm. Harry doesn't know this, but they know it. They don't yet know what Alexis' situation will be when facing the dementors alone, but they know that their time is not many.

"This way!"

Black stopped arguing with Snape. He pointed to the left, casually shot a prisoner who was moving slowly and looked like a zombie to death, and took the lead to run over.

Snape struck back with a sharp strike, slit the throat of the prisoner behind him who was trying to sneak up on him, and followed closely behind.

The two people ran quickly along the dark and narrow corridor. Along the way, they could see that the doors of the cells that should have been closed had been opened. Some of them were empty, and some prisoners were trembling and crawling out.

Black led Snape around a corner again, and a scream was heard, causing the two of them to stop.

A crazy woman wearing a black cloth outfit with hair as curvy as instant noodles was smiling exaggeratedly, walking around a blurry black shadow.

This woman has fair skin, a slender figure, and her beautiful appearance is completely ruined by a crazy and twisted expression, which makes people shudder.

Snape and Black stopped.

As if hearing the movement behind her, the woman turned around.

She lowered her head slightly, her eyes turned around the two of them, and then stared at Snape.

"Look! Who's here!"

"Isn't this dear Severus!"

"Why are you hanging out with my stupid brother?"

"Come here, Severus!"

Snape tightened his grip on his wand and spoke the woman's name syllable by syllable through gritted teeth.

"Bellatrix!"
