Bill Cipher Was Picked Up by a Good-for-Nothing Young Lady

What will happen when Qianxin Qianying gets killed by a heartless author and turns into Bill Cipher from Gravity Falls?

If some other author were writing this, the world might be peaceful and safe. What a shame, what a shame. Not one of the protagonists in my stories is normal. Tremble, quake with fear: a new god has arrived. Too bad the protagonist can't be bothered to rule the world, or Hell would be unleashed here.
