Su Li felt that this Undead Mage was more like the tabletop games he encountered in his previous life. An Undead Mage hypothetically has 200 points of magic power, and he has to figure out how to arrange a troop system himself. High-tier, powerful troops might consume magic where just one Corpse Demon Knight can cost up to 10 points, while a squadron of ordinary zombies or skeleton spearmen might only need 10 points total.
As the undead under its control grow stronger, it must constantly increase its black magic energy, almost pathologically pursuing the secrets of death and immersing itself in death magic, only by doing so can it avoid the backlash from the monsters it summons.
And long-term contact with dark magic is bound to cause the body to become cadaverous: skin pale and dry, emitting the stench of grave soil, even needing to rely on a black magic pool to slow aging.
