Plague Lord: All My Troops Are Corrupted

Xu Ran, who has been in this world for 18 years, awakened an F-level territory with full growth potential. As he continued to level up, he discovered that there were not only humans but also Zerg in this world. He also slowly learned that there are 13 unspeakable beings in this world: The Lord of Scarlet, the Lord of Corruption, the Lord of Perdition, the Lord of Fall, the Lord of Chaos, the Lord of Greed, the Lord of Desire, the Lord of Exaltation, the Lord of Anger, the Lord of Indulgence, the Lord of Envy, and the Lord of Confusion. Why only twelve? There is another one, no, that is a pervert.
