After the mist of the Gate of the Abyss dissipated, Roy found himself back at his starting point in the Abyss, but Demon Lord Rogeros had already disappeared.
Due to this, Roy had no choice but to bring Fat Tiger back to the place of refinement where he had promoted and then contact the high-rank demon Edrach to submit the mission.
The place of refinement was still the same. From time to time, low-rank demons would come and enter the pool to complete their promotion. As for those who failed to promote, once they left the barrier, they would immediately be hunted down by the middle-rank demons loitering outside. Such a unique ecological cycle, who knew how many existed in the Abyss…
After arriving here, Roy poured his magic power into a demon gate according to the method that Edrach had left. Soon, the demon gate was 'living' again, and the aura of the high-rank demon Edrach appeared.
