The operation was a complete success.
Ion was dead and the void storm had been completely blown out by Rhode, which meant that he eliminated one of Chaos's abilities to strike. As the void storm couldn't differentiate between time and space, even if one were to use teleportation, it wouldn't work. As long as one were planning to enter the Dragon Soul Continent through the void storm, one would surely head down a road to ruin. This way, there was one less offensive channel for Chaos, and Rhode could deploy his forces to defend elsewhere. Despite all these circumstances, the battle that Rhode planned was perfect from start to finish and could be said to be almost flawless. However, Ion's last words sickened him.
