If Sterl were aware of the thoughts running through the minds of the legendary warriors and demigods, he would probably chuckle. To them, the Celestial Stars—which could even challenge gods—were the monster's ultimate power, not to mention the Divine Light of Destruction.
But in reality, the Celestial Stars was merely one of the most basic area-effect abilities that Sterl had mastered. As for the Divine Light of Destruction, it was a powerful single-target attack that, honestly, was a bit of a waste against these lesser beings.
The ability Sterl truly favored was a combination of the Temporal-Spatial Law and Moon Law, which he used to first immobilize his enemies and then, with the terrifying power of space, immediately crush them!
