Lightning Wrath of Heavenly Turtle
"Defend with all your might!" Krune shouted as he condensed a gigantic layer of ice by expending all his Godly Energy, also increasing the size of Pestlor to create a second layer. After that, he sent out a bolt of tribulation lighting using his Spiritual Mark, intending to weaken the beam of tribulation as much as he could.
As for Sterlena, she exhausted her Godly Energy, infusing everything into Krune's abilities, reinforcing them to the limit. In any case, strengthening them was better than erecting more barriers. After all, having a stronger barrier was necessary as compared to multiple barriers in such a scenario.
Moreover, she had morphed the ice barrier in such a way that it would only give in after the entirety of it was destroyed. A hole couldn't be poked through. So, this meant that the tribulation beam would have to fully overpower their defenses and absolutely destroy it before striking them.
