Back in the day, the governments of nations could still pose quite a threat to Lu Xuan. After all, he nearly died in the south pole after the US bombarded him with a nuclear missile.
Lu Xuan failed to see much of a challenge in dealing with the forces still lurking in the shadows behind the nations. The Vampiric Empire and the Roman Curia were two examples of such forces among many others that could still pose a threat to him.
Even so, it did not matter if he was facing the Vampiric Empire, the werewolves, and the Roman Curia. In his current state, Lu Xuan saw everyone to be nothing more than insignificant insects.
Lu Xuan believed that such forces were not even worth a second of his time at all.
As long as they knew their place, he was willing to leave them be. If they stood in his way and caused trouble, however, he would have had no problems with having to get rid of them.
