After You Drove Your Hated Master to Demonic Fall, You Regretted It

[System + decisive and ruthless + face-slapping + girls' love + cool white-haired disciple VS Blood Demon King master + strong heroine + master is stronger at first, then the disciple, and finally both are strong + a little meme humor + unlocking new skins] I basically wrote this on a whim, so those who love to criticize should stay away. I won't drop it. If there's a day I don't post, it just means I definitely forgot. (A gentlemanly bow.) When people are betrayed, tormented, misunderstood, or about to have their cultivation stolen, they get all aggrieved and teary-eyed. When Yun Qinying faces these things: One self-detonation in each hand. None of you are getting out alive! If I can't have a good time, neither can anyone else. She also unlocks the System. When the System arrives, people are thrilled and fawn all over it. Yun Qinying: A puny little System? Easy to handle. When people fall into demonic cultivation, they're incredibly anxious, desperate to die. Yun Qinying: She gets nervous too. But when trouble comes, she still goes straight to self-detonation. No one's getting out alive. When people learn someone planted a demon stone in the secret realm to frame them, they panic and start figuring out how to explain themselves and beg the System for help. Yun Qinying: She goes straight to find the demon stone and use it to make a demonic weapon. Then she forces the System to give her a drop of beast blood and turns into a beast, going completely wild. After entering the Demon Realm, Yun Qinying inexplicably becomes one of the Blood Demons, the very people she'd always dreamed of joining. And their king acts like she's got a screw loose. She really turns Yun Qinying into a Blood Demon second only to herself. Then who would've guessed this foolish Blood Demon King was actually her master?! Yun Qinying: Seriously, is this right? Then somehow, they end up together. What now? Anyone got a guide?
