Everything is mana and everything belongs to the monarch
The first lightning struck at high speed and with ridiculous force. It was an attack that the previous Kayden wouldn't have been able to handle easily, it would have taken a lot of effort on his part, but now? His domain absorbed the lightning completely and distributed its attack force easily across dozens of kilometers.
Kayden didn't even blink at the first bolt. The second came even stronger and suffered the same end. He was at a much higher level of strength than before. Your choices were correct. Your constant maximizations were correct. He was walking a perfect path. The third ray had the same result.
Merlin was not impressed by this. The first rays weren't powerful. He was slightly surprised when Kayden did the same with the fourth ray. Not even two seconds had passed from one lightning strike to the next, yet Kayden's dominance remained undefeated.
