Starting from the Planetary Governor - Chapter 1173 - 634_2

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?

“What does it feel like to be a shadow?”People say it's bondage — the absence of light, of freedom. But what is freedom, really?The ability to choose whatever you want?Or... just a beautiful illusion masking the void?Strange question, I know.But you'll understand soon enough.Because my lives?They've always been a little... enlightening.— Kaiser

Bai Yuxue floated in the world for decades as a soul, and was reborn once.

Excited, she immediately hugged the baby girl in her arms: “I just want to take my daughter to be beautiful alone!”

In difficult times, she lived in poverty and lacked food and clothing. She was an orphan, a widow, and a mother without support. Can anyone step on it?

Don’t be afraid, there is a simulated ranch management space that you bring with you. Move your fingers, make a fortune, and get rich again, and you can’t climb high in the blink of an eye.

Since then, Bai Yuxue has set a small goal for herself: to make her daughter’s daughter fat and happy as quickly as possible.

But, where did this man come from?

Bai Yuxue: “Sir, my man is already dead, don’t try to pretend.”

Someone: “Because I miss you, I borrowed from the King of Hell for another lifetime.”

Through the wind and rain, overcoming thorns and thorns, just to hold you in my arms again.

Bai Yuxue: “Well, let me slow down first.”

Little girl: “I hate you, don’t rob my mother from me!”

- Description from novelbuddy

One day, I woke up only find out that I’d become a Demon Lord, an individual responsible for protecting a dungeon. The world I’d been spirited away to was one filled with violence. Gigantic monsters wandered through it and competed with each other each and every day for the right to survive. I had no choice but to strengthen my dungeon’s defenses in hopes of living another day—or at least that was what I’d thought. For some odd reason, I instead ended up spending my days in relaxation and bliss.
