I, the Sacrifice, Somehow Killed the Evil God

Upon learning that his childhood companion had been selected as a sacrificial lamb for the malevolent deity, Elt resolved to take her place and journeyed forth to the deity’s domain. Confronted with the malevolent deity, he deftly deployed his “Inventory” skill, enabling him to withstand the deity’s attack unscathed. Thereupon, he launched a crushing counterblow that vanquished the deity and laid claim to its trove of treasures, including the “Divine Sword Borumunk.” However, when he attempted to depart using the magical portal he had employed to arrive, he discovered that it was no longer operational.
Faced with no alternative, Elt had no choice but to abscond from the deity’s stronghold and endeavor to return to his village. He soon realized, however, that the deity’s lair was situated quite distantly from his home. Will he successfully journey back to his village and reunite with his erstwhile friend?
