I Just Became a Priest, and the Perfect Holy Emperor System Is Here!

When I first arrived in another world, the system was thirty years ahead of schedule. [You traveled the continent, made friends, and after more than twenty years, you finally sealed the resurrected evil god with the supreme warrior. Peace is always short-lived, and the minions of the evil god pollute the body of the supreme warrior into a lich. As the honorary Holy Emperor of the church and the imposer of the evil god's seal, you once again pick up the scepter that represents your identity and embark on a journey to eliminate the evil god. [Mission: As the honorary Holy Emperor of Morning Light Church, how can I watch my former friend be humiliated! Please go to the place where the journey begins, purify the lich transformed by the supreme hero, and eliminate the minions of the evil god] [Fixed reward: Attribute point +1 and additional rewards based on the player's task completion. Sitting in the confessional and listening to the chatter of the believers, Ciel looked at the system panel and then at his shabby linen clothes, and couldn't help but fall into deep thought. Am I the Holy Emperor of the Church? Hmm... It seems like the wrong person came to this system! But it looks like it should be barely usable! But who is this supreme warrior? Did he become a lich so long ago? Could it be that I have to turn him into a lich and purify him?
