Imperial CEO's Overbearing Love - Chapter 1011

A recurring nightmare afflicted Khan's nights since the Second Impact. His dreams replayed the scenes of the crash of the Nak's spaceship, an alien race that the humans had defeated five hundred years ago.

For the man’s promise, Xiao Chen returned strongly, the bodyguard of the body of the beauty president, sweeping the enemy of all directions, composing the legend of the king!

- Description from Uukanshu (translated)

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?

“Young Master Huo, Ms. An said that she wants to be the world’s top supermodel.”

As a result, news of the Huo Conglomerate entering the entertainment industry shocks the entire world.

“Young Master Huo, Ms. An said that she wants to get married at the age of 28.” The man’s gaze deepened as he replied, “That’s too late.”

The little bun behind him secretly hands him a household registration book and declares with a nasal and innocent-sounding voice, “Daddy, I will pay for your nine-dollar marriage registration fee!”
