Bai Yi traveled through another world, awakened the only SSS-level professional Shadow King during the job transfer ceremony, and took charge of the power of shadow. From dungeon experience to joining the Dragon Kingdom's strongest alliance, he continued to expand the Shadow Army. Facing powerful enemies and treacherous copies around the world, he turned the enemy's shadow into a soldier and used the shadow to devour the light. Whether it's the hidden BOSS of "Tidal Disaster" or the unreturned mystery of "Honolulu", they all become his ladder to the top. This is a journey to become a king with shadow and shine for the Dragon Kingdom.
