MTL - Black Dragon Kingdom - Chapter 423 trembling all vested interests

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?

A Wicked Witch, trailed by vengeful spirits and curses.“Hey, Tin Can! Did I not tell you to stop causing trouble?!”A Courageous Lion, descended from the bloodline of a hero.“Uh, no matter what, this seems like a bit much, no? Huh? Whatever doesn’t kill you only makes you stronger? Um, Sir Knight? Sir Knight!?”A Scarecrow, sealed away for pursuing the taboo.“Despite appearances, I’m quite capable from the shoulders up. Below that, you say? Let’s see, if I had to give a cold self-assessment… perhaps an emergency shield?”A Solitary Tin Knight, forever barred from human warmth.[The ‘Tin Knight’ urges everyone to initiate the boss battle, saying the cut scene is over!]This is a cruel, fairytale-like adventure story told by twisted protagonists.…Maybe!

He died on the wedding of the girl he had a crush on, after a long and successful career. After convincing Yama to send him back to the world, he decides to fix the areas in which his life went wrong. Realizing the lack of love and romance in his past life, he sets out to conquer the hearts of various women.

In his previous life, Tang Shi was a cannon fodder. For a jerk, he even turned down a blind date his father arranged for him, but finally died in the hands of his lover and half-blooded elder brother.

Before he died, his elder brother told him that the one that always went against him, teased him and used him as a bait was the one who truly loved him, also that blind date his father had arranged for him—Yan Xu.

Feeling regretful?

What would have happened if he hadn’t made that kind of choice from the very beginning?
