Strike while he was weak. Finish him off.
This had always been Rex's rule for survival. Show enemies no mercy, and once victory was assured, press the advantage.
Countless films and television shows from his previous life had taught Rex that lesson.
Those infamous figures, ruthless and immensely powerful.
Those classic villains were often stronger than the protagonists, yet they still suffered crushing defeats at the protagonists' hands. Why?
Because at the final, critical moment, they always found some excuse not to press their advantage and finish the protagonist off. Instead, they started talking endlessly, giving the protagonist a chance to turn the tables and stage a desperate comeback.
If those villains had simply embraced the principle of finishing an enemy off while he was weak, what chance would the protagonist have had?
Rex would never make such a classic villain's mistake. His armor had just given him the advantage, catching Neptulon the Tidehunter off guard and dealing him a heavy blow. What was he waiting for instead of using that advantage to secure victory once and for all?
Thus, the moment Neptulon the Tidehunter's body began to crumble, Rex shot straight toward him through the sea like a cannonball. The Ashbringer in his hand blazed with dazzling light, shining golden like the sun.
Neptulon the Tidehunter's vision was severely impaired.
The holy light was already an exceptionally brilliant form of energy. When it erupted, it was practically a miniature sun. Anyone who saw that dazzling radiance would instinctively close their eyes at first glance.
Ordinary people, however, truly could not fight this way. Making the holy light shine as brightly as the sun required an enormous amount of it.
Expending so much holy light merely to produce that effect was an extravagant waste that most people would never consider.
