Every civilization goes through birth, growth, maturation, and decline. This is the same as wizards who go through birth, old age, sickness and death. And from the perspective of time, space in any dimension will also be transformed in change. It's just that this dimension is too vast for ordinary life to perceive.

Before the apocalypse. Demon gods rule the entire universe. The world in which these demon gods live is completely different from the world we live in now. They are more free and can fulfill almost any of their desires. Immortal, with endless energy, and with the support of magic, they can even build their own universe.

After countless eons passed, the magic of freedom in this world began to dry up rapidly. The resources that the demon god relied on to survive began to decrease rapidly, which eventually led to the arrival of the calamity.

If you consider the entire wizarding world, or even the entire wizarding world, from the perspective of measuring calamity, it is nothing more than an ant-like existence that is not worth mentioning. All life on this planet, including wizards, could be completely destroyed in the event of a dimensional war.

This may not be clear to other wizards, but Xie An has seen a terrifying weapon like the Death Star with his own eyes, and he has also seen how the Lord of the Star Skeleton fights and destroys between the stars.

Even Xie An's master, the strongest doomsday warrior, could do very little when facing a god-like creature like the Lord of the Stars. Faced with such a catastrophe, mankind can only watch death and destruction befall him.

In the face of such a terrible catastrophe, mankind has no choice but to unite and fight for a glimmer of life. Things in the wizarding world haven't gotten to such a bad level today, and at least for now, wizards haven't encountered completely invincible enemies.

The secret in the Forbidden Forest could not be solved for a while, and after Xie An and Luna Hermione had breakfast together, they were taken to the Quidditch court by their girlfriend Qiu to prepare for the Quidditch national team. Xie An originally wanted to find an excuse to continue to go to the forbidden book area to study the notes, but he didn't expect Hermione to want to see it too. Xie An considered that it would be difficult for him to find anything alone, and because he was very busy during this time, he had little time to accompany Qiu, so he agreed to go with Qiu to participate.

Although Xie An didn't know, it didn't mean that Hogwarts School of Witchcraft and Wizardry didn't take this matter seriously. After coming out of the Great Hall, there were more students, and it seemed that all the students at Hogwarts School of Witchcraft and Wizardry had come out of some hidden place today.

What made Xie An even more strange was that the students changed out of their usual school uniforms and magic robes, and instead put on the uniforms of the Quidditch teams they supported. Some first-year students, who don't have uniforms, bought a badge from the twins that could be constantly changed and pinned to their chests to look like strange man-eating flowers.

"Don't you have to go to class today? These students seem to be quite comfortable. Xie An couldn't help but ask. Except for those sixth-grade graduating students, it seemed that the entire school was in action.

"Haha, Headmaster Albus Dundedo has announced that he can take a day off today, but he will make up for it on Saturday. Cho wrapped a scarf around Shea'an's neck that looked like a clumsy dead snake, which was said to be a memento of the Quidditch team in Northern Ireland.

"What kind of scarf is this? It looks so ugly. Luna couldn't help but laugh.

Cho was not angry, and laughed himself: "I heard that the Irish team thinks that their leprechaun's mascot is not domineering enough, and is ready to use the earthly snake Jörmungandr as their new mascot." ”

Hermione was stunned for a moment, and said strangely, "Isn't that a monster that brings bad luck?"

"No, in the wizarding world, Loki and his children are extremely powerful magical creatures, among which Loki is known as the god of fire magic, and is an extremely powerful wizard in ancient times. Luna explained.

Many legends in the wizarding world are not the same as those in the Muggle world, for example, some creatures in the Muggle world are very vicious, but in the wizarding world they are legendary wizards.
