The Demon King Decides to Spend Money

I'm back with an update now that things have settled down! 4.8 As a pay-to-win beta tester, Qiao Qiao drew a whole pile of useless cards and furiously blasted the developers, then quickly abandoned the trash mobile game. Not long afterward, she transmigrated into the very same trash game, becoming a helpless Demon King. Now she's tasked with farming materials, clearing dungeons, grinding events, and restoring the demon race to glory! First, she has to face the demons she abandoned, who are now full of resentment... The Demon King before spending money, weak and helpless: I'm sorry, I know I was wrong, please don't hit me, sob sob sob. The Demon King after spending money, powerful enough to kill anything in one blow: What the hell are you saying, kid?! Qiao Qiao: I'm going all in! #I'm diligently restoring the demon race, while all my subordinates are caught up in palace intrigue# Mary Sue, written for my own enjoyment, made up as I go (x). All kinds of nonhuman characters, futanari, and genderless characters, plus a tiny bit of Lovecraftian flavor. The demons have unconventional values, but the author is a good person! Please mind the tags, mwah! Weibo: @BigBattleAnytime, just a goofy internet user. Going premium on 2.7~ Thank you, lovelies, for spending money to support me, an R-rank card QAQ 70%, 36-hour anti-piracy delay~ Thank you, lovelies, for your support.
