The Martial convoy departed almost immediately after picking up Rui. Intercepting the alliance Martial force required setting off at once to ensure that they didn't allow the latter to get anywhere near the Shionel Confederation.
Of course, every single Martial Artist knew that the Shionel Confederation was irrelevant in this operation.
Both sides had the exact same two objectives.
The first objective was to prevent the other side from interfering with the battle. The alliance was especially anxious to ensure there was no interference. The Kandrians wished there was interference, but, unfortunately, the Void Prince had leveraged his power to get the fight that he sought.
They could not stop it.
The second objective that both sides universally shared was to protect their black-haired and black-eyed Martial Artist if he won; if he lost, they would kill the enemy Martial Artist.
