Picking up Girls With My System - Chapter 371 Ghost Town?

I fell into a game world out of nowhere with an instant kill skill.
And then somehow, I became a bigshot.

“P-please let me go..” I stammered and before I knew it, I was word vomiting while crying. “—I won’t return. You won’t ever see me again. I know you don’t want me as a mate. You hate me, so please let me go.” I cried out.Cain’s jaw tightened with each word that left my lips “What gave you the idea that you have the power to choose what you want?” His voice was low, “You don’t get to decide what, how, and when you leave. Only I get to do that. You don’t get to leave me, you don’t get to run! You only leave when I want you to.”“I didn’t ask for this,” I whispered, trembling. “I didn’t ask to be your mate.”Cain stepped back, “Neither did I,” he muttered under his breath. “But the bond doesn’t give us a choice, does it?”~~~~As the only child of her late Alpha father, Avery Jae was meant to inherit her family’s legacy.

Haunted by his dark past, he has vowed never to take a mate, yet the moment he lays eyes on Avery, everything changes.With a single word, Avery is bound to Cain—whether he wants it or not. In a world where betrayal runs deep, can Avery ever trust the alpha who might just be her worst enemy.

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?
