What Bad Intentions Can an NPC Like Me Have?

I am a powerful NPC. I don't have to do anything. I just need to issue tasks to the players who have traveled through time. As an NPC and a guide for players, what bad intentions can I have? Don't I just want everyone to level up quickly and clear this world quickly? What's wrong? But the system just refused to give it, saying that it must be gradual and gradual, and it cannot be improved too fast all at once, otherwise no one will play their game! Each world has its own system, and as long as I meet the requirements of these systems, I can get a vacation and return to the real world. It's so difficult for me! I work as an NPC all year round, from morning to night. I just want to marry a virtuous wife and start a family. What's wrong with me? But these players don't allow it! "Are you the guide of this village? You must be the final boss, let me show you your true colors!" A Bagua mirror appeared in the player's hand and shone on Yang Hao's face. Yang Hao completely ignored it and silently reduced the rewards for the tasks he was about to accept to single digits. This novel and its characters are purely fictitious.
