Collectibles was one of the ways Xi Wei motivated his players to complete their daily quests, among these collectibles were things like dances, various accessories that didn't take up an equipment slot, and some other fun tools that didn't have much practical use.
He believed that the players who had gotten bored due to the recent peacefulness would start grinding through their daily tasks again.
Of course, Xi Wei wasn't spending his time in the Divine Kingdom conjuring up ways to get players addicted, aside from digesting the remaining bits of the Aquatic Lord's divinity still sitting in his stomach, he was wondering how he could improve his players' skills.
After all, the enemies his players faced before weren't really deities like him, they were more like lesser gods that didn't have any godly blessing.
But as his players' territory expanded, it was inevitable that they were going to face believers of much more powerful deities sooner or later.
