MTL - Unscrupulous Enchantress: The Young Miss Has Arrived! - Chapter 657

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?

PS. Cover not mine, I just found it on google.

In the mortal world, the grass and trees are in autumn, she thought she could live her own life happily, but she did not expect to shoulder the heavy responsibility of revitalizing the family.

She has a very high spiritual root value, and it is reasonable to say that she is a rare genius. However, Lei Shuimu is such a fucking spiritual root that she can electrocute herself. How should she shoulder the responsibility that the Dao has entrusted to herself?
