This was Bologue's first encounter with the Prayer Believers. Faced with such an existence above his own, he was fully prepared. He knew that just as he had his own cards to play, so would the opponent. And with the gap in tiers, no one knew how the battle would unfold.
Thus, from the very beginning, Bologue knew he had only one chance, either to severely injure or even kill Sandbox, or to hide his edge and absolutely not arouse his warning.
The Decree of Rotting Flesh was a troublesome Secret Energy; Sandbox was practically as if he commanded a Ghoul army. Under the mist created by the Misty Secret Sword, these stitched-together Ghouls protected him like a Forbidden Guard.
If it were Kedening here, his Secret Energy would be of no use. Kedening's vision couldn't even detect Sandbox, but the Bright Light Blade in his hand was different.
Since becoming a Condenser, this was the most lethal Alchemy Armament Bologue had encountered, and its Ether consumption was also astonishing.
