A War?
Upon hearing Ji Yuyan's words, the initial reaction of several Holy Masters was one of disbelief.
The Immortal Alliance, as a behemoth spanning aeons, had existed even longer than the entire ancient history of the Cangyun Realm.
If there was an enemy within the universe that could make the Immortal Alliance take them seriously, it would only be the Martial Hall.

Moreover, it was not difficult to discern from Ji Yuyan's words that the Immortal Alliance did not even know who their opponent was, which was somewhat ludicrous.
