The defense of Hogwarts was a classic battle-and an utterly one-sided one.
That battle also gave the various factions a clearer understanding of how to fight with Elemental Magic.
So Elemental Magic could be used like this, too.
So Combination Magic using Elemental Magic could be this terrifying.
So they had still underestimated Elemental Magic.
People from factions all over the world began making preparations at once.
They researched and developed more powerful Elemental Magic, Combination Magic, combat strategies using Elemental Magic, and more.
Though they had little time, they had no choice but to press ahead.
Demons in various regions had not stopped wreaking havoc.
Special forces, armies, fighter jets, rocket launchers, and more were already being deployed in an all-out campaign against the demonic forces.
But individual demons were powerful fighters, and could even turn others into demonic servants.
These demonic servants were also fast and quick to react, spreading their ranks as rapidly as a zombie virus.
Some countries therefore sealed off their borders against these creatures and even launched missile strikes to prevent casualties on a greater scale.
Some innocent civilians died alongside the demons as a result.
Besides the demons, marine animals were also being transformed on a massive scale following the arrival of certain powerful beings from other worlds. While mutating some species, these beings also created tsunamis that began flooding the land and attacking humanity.
Battles and casualties occurred every day, while the mastermind behind it all, Thanatos, remained hidden somewhere, savoring the deathly energy gathering from across the world and the souls collected for him.
Almost all the souls of those who died in war were shrouded in fear and resentment.
In the Death God's hands, such souls were the finest nourishment, as well as raw material for creating evil spirits.
