"Now, Why Did I Transmigrate Into a Protagonist?!?"

Liú Zhēn, a certified novel junkie, He'd also torn into bad writing before, but Heaven's Rule? That steaming pile of cultivation nonsense had him seeing red. The protagonist, Mèng Yīchéng, had it all-perfect family, a rare Heavenly Spirit Root, and a spot at the top of the sect. Meanwhile, Mèng Xīngyào, the so-called villain, crawled through life like a cockroach only to get squashed and tossed aside like yesterday's garbage.
So why was Liú Zhēn, a 20-year-old college student with a schedule more messed up than his sleep cycle, so invested? Simple: the novel sucked (╯°□°）╯︵ ┻━┻, and tearing it apart gave him life (•̀o•́)ง.
Fueled by rage and caffeine, he ranted online before going to sleep, feeling victorious. That was, until the next morning when karma decided to slap him in the face. No homework? check. Running late for class? Of course. Raining like the heavens were out for blood? You bet. (╥﹏╥) To top it off, his family ditched him, leaving him to trek through the downpour like a wet rat.
In his brilliance, he chose a shortcut through an alley, where a puddle of doom awaited. In his rush, he missed the live wire lounging in the water until it zapped his sorry ass straight to an early grave. (╥﹏╥)
When he opened his eyes again, he wasn't in the afterlife. Nope, he'd been dumped into the same godforsaken novel he'd just trashed. And to top it off, he'd been reborn as the protagonist.
Lucky, right? Wrong. Liú Zhēn didn't want to be some hero-he just wanted to nap. But fate had other plans.
Instead of a Protagonist System, he got the Villain-Biased System. Mission: rewrite the villain's ending. Plan: "Follow the damn steps." (╯°□°）╯︵ ┻━┻.
Now, stuck with a snarky system and a villain smarter than he was, Liú Zhēn realized surviving the novel was a whole different nightmare. Can he fix the villain's fate and still get a happy ending? Or will another twist knock him down? Either way, he's in for it
