Shadow's Hand - Chapter 11: Link

Before her rebirth, Wei Luo was an innocent little girl.

“I'm a fox girl, Master!”

Leveling up is not tedious if you have adorable girls by your side!

Leon started his second life with a challenging and callous test to receive a system, only to begin his first steps in another world with an adorable fox girl by his side.

How would these two start their journey, and who else will join them? What will Leon achieve in a different world? He may find more than just new happiness.

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?
