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. Sun Hao, please introduce yourself briefly!

Hmm…how should I say it?

It should be said that among writers, I am the best at singing; among musicians, I am the best at acting; among actors, I am the best at directing; among directors, I am the most handsome…

As far as our appearance is concerned, it doesn’t matter if it’s Xiaogang Yimou Kaige in China or Cameron Spielberg in Hollywood, one word, it’s all instant kills!

Uh… Mr. Sun, let me remind you weakly, “Seckill” seems to be two words! ?
