The master of Heavenly River Palace deep down did not want to make the sect a pitiable and lowly entity. Their previous alliance with Pillfire City was made out of no choice. After all, they were neighboring Pillfire City, and if they did not listen to it, Pillfire City had plenty of ways to annihilate them.
Even if they didn't annihilate them, they could weaken them in many ways, marginalize them, and remove them from the ranks of a first rank sect!
Now that Pillfire City was gone, if they still shamelessly sought refuge with the Windcloud Sect, it would be a willing fall from grace.
Last time, Young Master Jiang Chen did not suppress them; this time, perhaps he would not hesitate to do so.
After much contemplation, the master of Heavenly River Palace still crumpled the secret letter, turning it to naught.
