One Experience per second. I am the Undead Scourge.

Kael had been ridiculed and ostracized in his past life for choosing the Trash Class of Necromancer, ultimately falling victim to a sinister plot and meeting a tragic end! He was reborn, returning to the very day of his class selection three years prior. This time, armed with the secrets of the Necromancer, he got his wish and once again selected the profession deemed a "joke"—the Necromancer! He also awakened a supreme System. While others still struggled with EXP and Level Up, he had already surged far ahead!
