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?

Before she met the system, Bai Yu always thought that she was a girl who was incomparably innocent who can’t understand.

After encountering the system, she dragged the sour and tired body day and night, greeting the system and the man for a thousand lives and 10,000 times.

– The final conclusion is that the body is fragile, and it need to be cherished.

This is a story of being crushed by one male after another.

And he even has the misfortune on the side that the retainer that he secretly gives his heart to, was stolen away from him.
