The issue of NPC followers' loyalty has always been a very mysterious domain. Da Fei has not participated in the game's public beta, so he doesn't know much. The common experience among players is simply to ensure good food, good drink, and nice living conditions, or sometimes not care at all since it's rare for bizarre player conditions to occur. Thus, NPC followers give players the feeling of being eternally loyal pets that never betray, allowing players to forever experience the joy of being the 'Bright Lord' in front of NPCs.
In fact, as seen from Da Fei's gaming experience, it is indeed so. Therefore, Da Fei trusts NPCs far more than he trusts players.
However, the current situation shows that high-intelligence NPCs who have defected from the enemy camp present a brand new challenge. Lamia is one such case, and this Prince Hillsea presumably is another.
