From Bullets To Billions - Chapter 179: The Colors Spread

A useless prince, yet brimming with kindness and compassion—his smile as warm as sunlight, illuminating this darkened era.But that was merely a mask, hiding the poisonous and mad nature beneath.A monster lurking behind a gentle shell.A system that feeds on stolen Heroines.He will outplay destiny—and rise as the world’s ultimate villain.

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?

There are times—far too many times—when you feel that uncontrollable urge to kill someone.For Kaya, this… this was exactly that moment.“Repeat what you just said?”She’d seen hell on the battlefield—second-in-command of a military unit, dodging bullets, dragging traitors by the collar, and coming out alive with grit under her nails.But nothing, absolutely nothing, prepared her for the sight of her spineless husband flirting with her own sister. Right in front of her.“I could never marry a barbarian like you. The one I... I like is Meera—”Blah blah. The same pitiful nonsense again.You think—what could possibly be worse than this?And then, right on cue, your idiotic sister chimes in, completely serious, “I just poisoned you.”Wow.BANG.Before anyone could even react, Meera collapsed.Dead.Her so-called husband gasped like a fish dragged out of water.“Y-you…”He dropped to his knees, staring at Kaya like he was seeing a monster rise from the dark.“You killed your sister?! How could y—?”BANG.Second bullet.Same spot.He dropped like a puppet with its strings cut.Silence....Just when Kaya thought her story had finally reached its bitter end, the universe—no, god himself—decided to throw in one last, ridiculous twist.“Wife… wife, didn’t you say you were gonna eat me? Why’d you stop?”A snake beast, ridiculously charming and glowing like some immortal fantasy, clung to her, eyes gleaming.Another voice interrupted.“Shut up! My wife wants to cuddle me now—”A sparrow beastman leapt into her arms, like that made any sense.“Hic… wife, don’t you want me anymore?”A panda-like beastman sat beside her, huge, sniffly, and wronged like a child abandoned at a festival.Sitting in the middle of all this, Kaya was absolutely dumbfounded.‘When the hell did all of this even start?’
