Avoid Yandere Constellation - Chapter 131:

Hutson, a man reborn into a ruthless and dangerous world, now inhabits the body of a young hunter in a small barony. With no connections and nothing to his name, he must rely on his sharp mind and cunning to rise through a medieval-like society. As he climbs the social ladder, he uncovers a terrifying truth: wizards, beings far more powerful than any knight or noble, rule over the world. Driven by this discovery, Hutson throws himself into the pursuit of wizardry—a path darker and more brutal than he could ever have imagined. In a world where betrayal lurks around every corner, Hutson seeks what all others desire: immortality. With his intellect and ruthlessness, he will stop at nothing to claim it for himself.

There’s SIS in great Britain, CIA in the US. In Huaxia, there’s Dragon Division, known as the mysterious power of the East.

When a soldier that originally failed to be selected to join, appeared on the Dragon Division’s list again, no one noticed, that this inconspicuous and humble looking guy was actually the Dragon King of the division, the one that’s most difficult to deal with.

He was a man, whose appearance gave every one existential crisis, including a fly that was consecutively caught by him with a pair of chopsticks.

Of course, this story is hilarious as well.
[Shen Yao laughed. “You think I would help you? For what reason?”

Xu Cheng sighed. “Shen Yao, to be honest, you are really pretty.”

“Humph.” Shen Yao snorted coldly, “Can you elaborate on that for me?”

“I don’t know how to get into details, but I can only say that when I accidentally tore your skirt today, I got a boner.” ]

[Character Deleted.]I deleted the character I had been raising for over 5 years.To finally defeat the final boss of Demon Fantasy—the one I could never quite beat.For the sake of defeating ‘Baal’.“…I can just start over. I can do it.”And then…[Special reward has been granted!]“What? A mythic-tier trait?”The perfect opportunity had arrived.“This time, for sure!”I’ll raise the strongest mage and take down Baal!At least, that’s what I thought when—[Welcome to Demon Fantasy.]I found myself inside a world teeming with 666 kinds of demons.And I had the ‘special reward’ I just received!“…Fine. Let’s see who wins this.”I was confident.After all, I’ve been a veteran of this game for 10 years.

I’ve had enough of being transmigrated into books.
