He found out that he is in a world similar to our own with a timeline akin to early twentieth century.

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?

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

After being a young master for more than ten years, he was reborn overnight became a ger who had nothing. This ger was still a lunatic!

Crazy people were hated in the tribe! He was also bullied and robbed! In the end, he was forcibly betrothed to a beastman that he didn’t even recognize.

After accepting the facts tremblingly, Wang Jin began to use the golden finger to reverse the adversity.

Being disliked by others and then becoming everyone’s favorite, snatching back everything that was robbed, as for… the beastman who was forced to marry…

Wang Jin looked at the man who had been standing by his side, and the man felt his gaze, looking back at Wang Jin, his indifferent eyes suddenly became warmer. He stretched out his hand and clasped Wang Jin’s ten fingers tightly, and said softly: “In this life, I only want you alone, no matter whether you are a little lunatic or not.

Wang Jin’s heart skipped a beat.

Forget it, this man… is quite interesting, so let’s keep him!

Years later, Wang Jin was pregnant with a big belly, gnashing his teeth with hatred when he saw the gentle and flattering man in front of him.

We agreed to only be together, and never get pregnant!

A man’s mouth, except for himself, was a deceiving ghost!
