This battle didn't require Ashu and Ymir to inflict significant damage on this Grand Swordmaster.
They only needed to speed up the exhaustion process; victory was just around the corner.
Therefore, Ashu tried his best to attract Demons.
Ashu wasn't worried that the Grand Swordmaster would ally with the Demons and gain a foothold in the Netherrealm.
Because if that happened, it would mean the Grand Swordmaster had sided with Demons, changing the nature of the conflict entirely. At that point, applying for a Demon Huntress Nun from the Holy Cultivator Guild headquarters would be a natural step.
He just needed to file the report, and plenty of people would approve the request.
Following the plan, the two saw the enemy's energy nearly drained, then performed a feint before quickly retreating.
By the time Grand Swordmaster Alonso Tiersha realized their intent, it was too late; the two had already used the convenience of being Death Devotees to swiftly return to the mortal world.
