Demon King & Hero - Chapter 7-1: Haaaah… I don’t even know.

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?

In a magical Middle Ages, it was difficult to stick to your beliefs…or even to be alone.

But… people’s constitutions cannot be generalized.

Lan En touched the two hearts and three lung sacs under his chest.

It is estimated that not only in this world, but also in other worlds connected by the intersection of the celestial sphere, I can maintain a healthy view of good and evil.

——Then get rid of all those hopeless scum!
