An Lin and Xu Xiaolan immediately came to the decision to beat the Dark Spirit King and the Divine Bat Emperor into submission first.
This operation was going to be focused on speed and stealth, so it would not be a good idea to deploy too much of their forces.
Xiao Tu and Xiao Ze were vital to the eastern front and could not stray far away from the Kingdom of the Nine States. As for the phoenix, Little Huang, it had to replace Xu Xiaolan and defend the northern front.
The defenses of the northern front were extremely fragile compared to the other fronts. Even with the likes of the Great Empress and the High Priestess among their ranks, it would still be too much for Xu Xiaolan and the phoenix to leave at once, so during the time in which Xu Xiaolan was going to be away, Little Huang had to defend the northern front.
