Chapter 316: Chapter 310 : [Void Opening Key]

"Please...enough." The demon weakly begged.

While it truly didn't want to admit defeat, the broadsword of light that Sato had used to inflict injuries on the demon had crumbled its will. The injuries it had received would require it a few dozens of years to heal and it wouldn't be able to store energy as quickly as it did before. This in turn would extend its sentence in this void prison and this was something the demon didn't want to see happen. Because of this, even if it were just for a moment, it decided to lower its head in front of Sato.

"Good." Sato withdrew the gigantic sword and dispersed it into particles.

The system notification had already alerted him that the mission was completed with even the demon begging him to stop. Attacking further was pointless unless Sato had a sadistic taste in torturing non-humans.
