Epic of Vampire Dragon: Reborn as a Vampire Dragon with a System - Chapter 417: Clash!

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?

“Mr. Xu, are you really a Heavenly Master?”

“As genuine as they come, more real than gold!”

“I’ve heard that your reputation in the supernatural circle is really bad, even to the point where a ghost once called the police saying you were threatening him?”

“Impossible!”

“It wasn’t me!”

“Don’t talk nonsense!”

Xu Yang clenched the Thousand-Year Peachwood Sword in his hand, and said, “What’s the name of that ghost? Would you dare to let him confront me face to face?”

(PS: This book is also known as ‘This Heavenly Master is too Vicious’, ‘Scaring Ghosts Makes You Stronger’.)

- Description from Novelupdates

This is the story where Urahara Kisuke died after Nel failed to save him inside Askin’s Gift Ball Delux and reincarnated in the world of DxD.

I am not sure if I can capture Urahara’s character properly so I apologize in advance if you are not satisfied.

Also, English is not my native language.

I don’t own any of the characters from the canon.
