Global changes, calamities come, and monsters plunder.

In order to resist monsters, the global data will be digitized, and everyone will get a combat occupation or auxiliary occupation through awakening and transfer at the age of eighteen, and they will become stronger by killing monsters.

Lu Yan awakened the weakest fighting professional undead mage at the beginning, but obtained the professional support system, and the second awakening concealed the professional undead monarch.

“Hahaha, I have awakened the Paladins, your Almighty King is here.”

Soon after, Lu Yan was wearing undead ghost armor, holding a ghost scythe, with an army of 100,000 undead behind him, and a scythe split the epic monster in half.
