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?

Tired of the schemes and strifes of city life, Bei Feng finally returned to his hometown in the countryside

While picking asters ‘neath the Eastern fence;

My gaze upon the Southern mountain rests;

Rearing a few chickens and ducks, I shall lead a simple and leisurely life!

However, who would have thought that fate would play a huge joke on Bei Feng? All kinds of magical items and beings of the Myriad Worlds could actually be fished out of the Ancient Well in his yard!

Even a chicken reeled out of the well ended up chasing Bei Feng all over the yard and beating him black and blue! Speechless and aggrieved, he asked the Heavens: if, that day, he’d fished out a Dragon instead of a chicken, what would’ve happened to him!
