Surrounded by Dementors, Snape's face remained unchanged, and it seemed that he could easily save Magos in the next second, but he was actually extremely impatient.

There were so many Dementors gathered around, not to mention that there was a significantly more powerful Dementor at the very end. When the number reaches a certain level, it will cause qualitative changes, especially the disembodied dark magic creatures in front of them, and the changes caused by their numbers reaching a certain level will be more obvious. Judging by the frost crystals that began to appear on Snape's magic robes, it was clear that he was not as calm as he appeared. Although they were not yet a threat to his life, he couldn't do it if he wanted to quickly repel them and save Magos, at best he was evenly matched. And looking at Magos's current state, he was worried that if he didn't save him quickly, he might be sucked up all hope by the Dementor and become a walking corpse full of despair, so he didn't even have time to break the Dementor's blockade and rush back to call people.

No longer hesitating, Snape pulled out his wand as fast as he could, and the Dementors around him no longer just warned and trapped him, but surrounded him with Snape as the center of the circle, and then used their best Dementor kiss.

The Soul Kiss used by nearly a hundred Dementors at the same time was a hundred times more powerful, and if it weren't for Snape's perennial Occlumency, he might have to rely on the Patronus Charm to protect himself now, but now it was different, he still had the strength to spare.

"The flames are blazing!"

A huge wall of fire appeared out of thin air at the location of the Dementors, although the fire was not very lethal to the Dementors, but they were naturally averse to light and quickly dodged and used their natural talent to reduce the temperature of the surroundings to extinguish the spell as soon as possible, in addition to aversion to light, it was also to prevent Dumbledore's gaze from being drawn.

The Dementor's actions were expected by Snape, he sneered, Dumbledore would definitely be aware of the magic fluctuations generated by so many Dementors, and all he had to do was to let Dumbledore know about the problem faster, but it was not enough, he didn't want to pin his hopes on Dumbledore to find out first, so he also needed a 'person' who could inform him.

"Divine Guard!"

A dazzling white light shot out from the tip of Snape's wand, and a huge deer with a silver glimmer appeared in an instant, and rushed towards Mygoth with Snape's will.

The Dementors, who had begun to disperse with Snape's Patronus Charm, seemed to have received some order, and instead of surrounding Snape, they gathered together and hovered in front of the more powerful Dementor to defend it against the damage of the Patronus Charm.

The deer's pace was stopped by the large number of Dementors, and when it saw that they were about to freeze like this, the deer turned around and galloped away in the direction of Hogwarts at a faster speed than before.

For the first time, the special Dementors, who knew they had been deceived, let out a scream similar to a wail, and ordered the nearby Dementors to stop the deer.

But how could Snape allow them to interfere with the deer, I saw him take out a starry potion from his arms, pull out the magic plug, and don't drink it, just swaying it directly in front of him.

The moment the potion was spilled, the little starlight seemed to absorb all the light of the moon, and the whole world seemed to have those starlights left, except for Snape, who had been in the Occlumency Technique, and even the huge Dementors who were attacking Magos were in a trance.

However, Starlight's effect lasted for a short time, and it returned to normal almost instantly, but by this time the deer had already run away, and the Dementors had no chance to catch up with it.

The Grand Dementor let out an angry wail again, realizing that Dumbledore would soon know what was going on. Normally, they should retreat when they know that an enemy they can't resist will soon be coming, but the reason why dark magic creatures are called dark magic creatures is because their hatred, hatred, and desire to destroy and destroy are always dominant, so instead of letting the Dementors leave, they let them abandon Snape and attack Maghus all.

Snape sensed that the deer had already arrived at the school, and he didn't need it to go to Dumbledore, knowing that Dumbledore must have found out what was going on.

Removing the Patronus Charm, he raised his wand again and used the Patronus Charm against the black pressure in front of him, not hoping to repel them, as long as he could stop them for a moment.

The Dementors had no choice, they couldn't resist the deer's contact without defense, so they had to let Magos go and turn around to defend themselves against the deer.

Dumbledore, who was concentrating on what was going on in the Headmaster's office, suddenly raised his head, he had just sensed Snape's Patronus.

With a wave of his wand, Dumbledore instantly appeared at the school gate from the Headmaster's office, and then he immediately saw the red flames and the magic fluctuations of the Dementors.

With another wave of his wand, he vanished, and he appeared next to Snape.

"Severus," Dumbledore had just called out Snape's name when he spotted Magos being attacked by the Dementors.

Dumbledore's calm gaze was quickly replaced by anger, and the raging flame seemed to be substance.

"Presumptuous!"

A loud roar was heard throughout Hogwarts.

Dumbledore's magic robes were windless, and he floated slowly, his wand pointed at the Dementors.

He quickly chanted the spell, which would have felt both familiar and unfamiliar if McGoth had been awake by now.

A red point of light slowly appeared on the tip of Dumbledore's wand, seemingly unharmed, but in the next second, the whole world seemed to turn red.

A crisp chirp suddenly sounded in the air, and then a large bird of flames was seen rushing towards the Dementors with an unparalleled momentum.

Seeing this, the giant Dementor let out an inexplicable wail, and then let go of Magos and floated towards the firebird, while the other normal Dementors fluttered around without resistance, unable to control themselves.

Snape walked up to Magos and took out a bottle of potion for him to drink, then helped him to look up, only to see the huge Dementor slowly dissipate like black smoke after touching the firebird, and he was so surprised that he couldn't maintain his expression unchanged for thousands of years. He didn't expect that the Patronus Charm that Dumbledore had obviously changed would be so powerful, and it would directly destroy a powerful Dementor, knowing that it could only dispel those dark magic creatures, except for making them weak for a while, it was impossible to threaten them.

However, after the resistance of the great Dementors, the size and momentum of the Firebird also dissipated a lot, but even so, the Firebird flew around them in a circle, and destroyed nearly half of the ordinary Dementors, and the rest of the Dementors were driven away by the afterglow for a long time.

McGoth actually saw this scene in his eyes, but after the attack of the Great Dementor, although Snape gave him an unknown potion, but he was still a little confused, and his brain didn't understand what was going on, only that the firebird was really beautiful and majestic.
