Heavenly Dao Engine - Chapter 17 - 00: Single Room

In a world where money and power trumps all, Ahn Soo Ho, A.K.A. Magician, uses his superhuman abilities and his knowledge of the intelligence world to climb to the very top of the totem pole.

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?

She is a top-class spy, a poison specialist, but also a young and cute girl with a sinister temperament. In spite of her sweet and innocent appearance, she can complete any tasks without the slightest hesitation. One day because of an incomplete black magic, she was sent into the body of a girl who was deemed as a good-for-nothing. What kind of change will she bring to this continent?

A Prince said with bitter hatred, “I thought she was weak and easily bullied, therefore I broke off the engagement. I really didn’t expect she is such a shrewd girl. I made an error of judgment.”

The Crown Prince deeply sighed, “She is such a sexy evildoer! Obviously, she has a frail and tender body, but I am not able to overwhelm her…”

Finally, an Emperor hit the nail on the head, “She is just a bit two-faced!”

She answered, “You’re just a big pervert!”

The Emperor carried her into the room and said, “You are predestined to be mine! A two-faced girl and a pervert are a perfect match, right?!”

Fuck me.I was just trying to pull my favorite character from a gacha game — Trafalgar du Morgain. The legendary swordsman. The cursed heir. The tragic side story no one cared to fix.Discarded by his clan. Humiliated by his siblings. Dead by suicide before the main plot even began.Guess who woke up in his body?Yeah. Me.Now I’m stuck in a game world that had zero lore, zero guidance, and zero chance of survival — except for the broken-ass Talent I somehow unlocked.I’ll kill, steal, lie, betray—whatever it takes.If survival means blood on my hands, then so be it.I didn’t choose this world, but I’m not going to let it chew me up and spit me out.I’ll climb over corpses if I have to. I’ll become the villain, the monster, the nightmare they never saw coming.Because in this world, there’s only one rule that matters: survive or die.And I’m not dying again.~~~More tags: no Yuri, no NTR, transmigration, rarebloodline, no dense mc, dragons, dragon girl, dog girl, vampire, succubus, mana cultivation, cursed heir, academy setting, secret identity, hidden talent, demons, death and rebirth, political intrigue, ancient bloodline, dark fantasy, family conflict.
