Pungyoui Yeosingwa Cheonjae Mangnani Sadonim

Earth’s life force is depleted, and it’s dying. Humanity’s only hope lies with Dispatchers, heroes sent to otherworldly realms to retrieve energy for survival. Chan-Su Oh is one of them, but despite his legendary father, he has zero talent. However, things change when Chan-Su is sent to the Block-Style Territory Expansion World as the Apostle of a forgotten, weakened Goddess of Abundance. Armed with nothing but a modified harvesting skill and a desperate drive to find his parents, Chan-Su must reclaim his territory block by block. From wretched outcast to genius apostle, the hunt to restore his Goddess begins now!
