Legendary Bloodline Collector - Chapter 8 Concealed Lethal Yin Poison

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?
