The moment Roy swallowed Kha-Beleth's soul, the first chain reaction he caused was the collapse of the demon army.
Among the surviving high-rank demons, especially the ones who were the commanding heroes of the army, strange flames suddenly appeared in front of them and burned to ashes their contracts… Almost all of them had signed a demon contract with Kha-Beleth to protect their interests. But now that Kha-Beleth was dead, one of the parties of the contracts was naturally gone, and it could not continue to take effect. Thus, the moment the contracts burned, the repulsive force of the world started acting on them.
These commanding high-rank demons had suffered injuries in the battle with Julia and Benia. As the repulsive force of the world surged over, someone was sucked into a Gate of the Abyss that suddenly opened!
They were directly expelled from this world!
