I Summon the Death Legion

> Betrayed, weakened, and left for dead, he returns with a second chance and a terrifying new system. This time, he will not run. He will summon the dead, conquer the dungeons, and make every enemy fall before him. The world thought he would disappear. Instead, he becomes the most powerful undead mage in history. And when the final apocalypse arrives, only his death legion will stand between humanity and total destruction.
