Absolute Regression - Chapter 249

Yang Lujia, a sought-after, handsome, sports-driven, and seemingly perfect man with an outstanding family background was killed in a plane bombing orchestrated by his so-called pals. Before he even knew it, his soul traveled through space, and his supposed-to-be ending unexpectedly took turns.

Unknowingly, he set foot into a world made up of five realms where strength matters most. Then, one day, following a mission, he started accepting disciples.

[Ding! The system has discovered an S-Class Genius! System’s Fifth Ability Unlocked: Disciple Acknowledgment!]

[New Mission: Recruit and acknowledge the Holy Flood Empire's S-Class Genius. The reward will be issued upon acknowledgment from both parties.]

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?
