After a Hundred Years of Qi Refining, I Became an NPC?

After transmigrating into a game world, Xiao Hong was stuck at the Qi Refining stage for a hundred years. Facing all kinds of unknown dangers, as well as the impending Fourth Calamity, the players, Xiao Hong decided to become an utterly ordinary NPC and use every means possible to survive until the end. As an NPC, it is perfectly normal for him to issue quests to players, right? What, he is exploiting the players? That never happened. That is pure slander! What, someone discovered that his health bar was thicker than the final boss's? Slander! He is only a little Qi Refining cultivator! Player: Yeah, right, your Qi Refining cultivator can instantly kill a Mahayana cultivator!
