Change In Plans
Hye asked her to just divert the attention of the Toranks away from here and force them to change their route of travel. She brilliantly succeeded in doing so, and yet she missed the goal of forcing the Toranks hands to use the secret weapon.
In fact, Hye didn't intend to let her force the Toranks to reveal that weapon. He wanted her to destroy as many ships as she could, greatly weakening the Toranks fleet. And yet with the short battle that erupted, the Toranks still preserved most of their fleets.
That was bad news for the waiting away pirate king and his fleet. Even if Hye sent more ships and warriors over to the pirate king, the Toranks seemed ready to return backwards again, and go for another route away from these ambushes.
Hye didn't want to see that. He wanted weak and totally exhausted Toranks fleets. Or else the Toranks wouldn't be forced to fight a battle of life and death with the pirate king fleets.
