The Three Treasures of the Moists Head to Heaven Official's Blessing

What would happen if the protagonists of The Scum Villain's Self-Saving System and Grandmaster of Demonic Cultivation all gathered in Heaven Official's Blessing? Pairings: Hua Cheng and Xie Lian as the main couple; Luo Binghe and Shen Qingqiu as a secondary couple; either Wei Wuxian and Lan Wangji or Lan Wangji and Wei Wuxian are fine. If you can't accept that, please take note! Um... Well, actually, while writing this, I couldn't decide whether it should be Wei Wuxian with Lan Wangji or Lan Wangji with Wei Wuxian. Since they're both strong, and I ship them either way, I don't really care which one tops. Read whichever version you prefer. Most fanfics of this pairing get a bit too intense, and I don't want the comments about them to get just as intense. As long as they're together in the end, that's all that matters. Read whichever version you prefer. If anyone brings real-life celebrities into the comments, I'll chase you down and curse you out for three days straight, and that's putting it mildly! The synopsis is already perfectly clear. If anyone still disrupts the peace in the comments or keeps harassing readers, I'll come after you too if I find out! If you like it, stay. If not, maybe we'll meet again another time. This follows the original Heaven Official's Blessing, with some Grandmaster of Demonic Cultivation and The Scum Villain's Self-Saving System storylines mixed in, though I've forgotten a lot of the plot. Please bear with me. It's an honor if my work can keep you readers here. Thank you for crossing paths with me, and here's to the things we love! A friendly reminder: If anyone seems out of character, please tell me right away, because it bothers me even more!
