Kill the Corpse Demon, the Fierce Mage

Six hundred years ago, the sudden appearance of the zombie demon clan broke the tranquility of the world. They were extremely ferocious and could eat people, constantly causing harm to the world, and countless lives trembled under their fangs. Faced with such a disaster, the government secretly organized the Demon Hunting Group, a group of brave and fearless warriors with "Qi". Their mission is to protect people and fight against the corpse demons. The members of the demon hunting group have their own characteristics. Some are good at melee combat, some are good at long-range attacks, and some are good at various tactics and strategies. Under their leadership, people found a way to temporarily suppress the corpse demon clan, but this only temporarily postponed the disaster. The leader of the corpse demon clan is a powerful corpse demon king. His power surpasses that of ordinary corpse demons. He is well versed in all kinds of weird spells and powerful power. Under his leadership, the corpse demon clan became more cunning and difficult to deal with. In order to fight against the Corpse Demon King and the Corpse Demon Clan, the members of the Demon Hunting Group must constantly improve their strength and find new strategies and methods. As the battle deepens, the demon hunting group gradually discovers that the origin of the corpse demons is not simply evil and greed. Behind their history lies an ancient grudge and unsolved mysteries. This history seems to be related to an ancient wizard who used forbidden power hundreds of years ago to try to control the world, but eventually lost control due to his own ambition, leading to the birth of the corpse demon clan. How should the protagonist group fight against and protect the world?
