Despite having reached the Nirvana stage, Lu Xuan remained completely unfazed. He had too many means at his disposal, and having his own Spiritual Aether sealed didn't mean that he was entirely powerless.
Lu Xuan still had many ways that he could go about killing people.
Deep down, he was fuming over what the members of the Jiang family did. The common folks of the Holy Sun Continent saw the Liu family as one of the clans who came from the descendants of the sacred ones.
There were many minor clans of such sacred bloodline spread all over the Holy Sun Continent. While the actual number of them remained quite small, they still existed.
In reality, exterminating the Liu family would've hardly been deemed an issue for most people out there.
Countless people went about calling themselves descendants of the sacred ones, after all. However, such claims were deemed utterly pointless if they hadn't awakened their sacred bloodline yet.
