Only My Flame Explosion Spell Shall Endure

Long ago, there was an age known as the Golden Age. Humanity's footsteps reached across several galaxies, and it colonized more than a million planets. A true mage's every basic attack is a Pyroblast. Xu Duo got saddled with an unreliable System that couldn't cast a single spell, except Pyroblast. “Die, you great Slime Demon King!” Xu Duo shouted. “??” The Slime. A Pyroblast shot over the Slime's head. Starting at Doran Academy, Xu Duo restores the academy, uncovers the secrets of the past, changes the empire's order, unites humanity's forces, and fights back against the Void's attacks. Above the Suspended World lies the Void, and below it lies the Abyss. The world is no more than a speck of dust in the vast universe. Laying the groundwork for mythical technology in a world of magic, then conquering countless worlds with the empire as his foundation: humanity will be great once again. This novel incorporates many elements from Warhammer 40K, League of Legends, Warcraft, Cthulhu Mythos, and more.
