Chapter 557: Emissary of the Underworld

..

Matthew had just stepped onto the porch of the Main Hall when he heard Rheagar bragging about his " narrow escape " from purgatory.

He heard his energetic voice.

Matthew was relieved.

In the office, besides Rheagar and Zeller, there were also the two Construct Knights, Dulin and Asma.

However, their condition was worlds apart from Rheagar's.

Matthew saw them lying limply on the sofa. Although they had not taken off their weapons, they looked lazy, weak, and extremely lacking in energy.

It was as if they had been sucked dry.

"... All in all, I used some tricks to deceive that bad woman, Lutisia. Then, I spread false news and created a diversion. In the end, I successfully returned to the castle and saved Dulin and Asma.

"Under my command, Matthew has successfully obtained the Holy Grail of Sin, so this operation was a great success!"

Rheagar concluded in a refreshed manner.
