God Level Demon - Chapter 109 - No. 1 on 3 Charts

William and his college class are ripped from Earth and thrown into Aethel, a world on the brink of collapse. Everyone gains incredible magical powers – except William. Mocked and underestimated, he’s an outcast among heroes. But William has a secret: an SSS-ranked skill that lets him travel to Aethel’s past. Learning lost magic from ancient masters, he’ll surpass his classmates and become the true savior Aethel needs. But can he overcome the dangers of the past and present to forge his own destiny? While others studied about the first mage, William could go back in time and see the first mage himself! While others dreamed of seeing a dragon, William could go back in time, hatch a legendary dragon egg and turn it into his puppy. While others used common materials to craft their items, William could go back in time and mine materials that weren’t find anywhere in Aethel anymore. Is it unfair? Perhaps, but William was not the type of person to not use the powers the universe gave him.

After centuries of ruling the underworld with terrifying power, Lilith dies in an epic battle, only to be reborn in the human world. But instead of a grand rebirth as a queen of darkness, she's reincarnated as something far more mundane—a secretary. Rather than despair, Lilith finds this new life amusing. After all, who would suspect the devil herself to be working a 9-to-5?Settling into her new reality, Lilith embraces her role, living in a luxurious apartment and working diligently in her office. Though her devilish instincts are hard to suppress, she's determined to be the perfect secretary. But when people push her too far, the devil within still comes out to play.When a creep in the office dares to look at her the wrong way, she calmly fixes her gaze on him. “You keep staring like that, and I'll show you what a broken wrist feels like.” The man quickly scurries away, leaving Lilith with a satisfied smirk.Even the rich, entitled girl from accounting isn't safe from her wrath. “You think you can push me around just because you've got money? I've burned entire kingdoms for less. Don't test me.” She says this with a calm smile, her eyes glinting dangerously.The day continued like that—stopping creeps in their tracks, putting rude heiresses in their place, and being the flawless secretary she intended to be. But, of course, her boss—the CEO—had his eyes on her, more curious than ever. And while the entire office might fear her or wonder about her, she remained blissfully indifferent. This was fun. And she wasn't here to impress anyone but herself.Who knew being a secretary could be so... interesting?

An Xu opened his eyes and found that he was in a world with both ABO and supernatural abilities.
She pinched her face hard, but it didn’t hurt at all.
So this female alpha and lightning power user happily thought,
It’s rare to have such an interesting dream, and I’m blunt. (=￣ω￣=)
A painless aristocratic girl who traveled to the world of ABO+ supernatural powers,
The mentally retarded otaku who thinks he is dreaming, lives as he pleases in another world,
I mistakenly hit the promotion and salary to be a unparalleled king.

Female A male O, simple and rude middle school girl (female lead/alpha) X feeds a tiger brain to make up a knight (male lead/omega), cool writing, puppy blood when falling in love.

An Xu: Hey, am I not a teacher of justice?
Chris: ……………
Everyone: (No, no, I don’t think it looks like the villain’s side is better!!)

3. The hero Chris is a growth-type holy father, gradually evolving
The above points should be cautious, if you can’t accept the setting, please let it go
