A modern loser man was cheated by his friends and traveled to an unrecorded country in history.
Time travel is not scary, but what is scary is that he was obviously a boy but became a girl.
Her father was framed and imprisoned. Before his death, he found a husband for her. This husband was not simple. He had a rich background and was an invincible general on the blood-sand battlefield.
When she found out that she was going to get married, she was completely unwilling to do so, but her parents were so angry that she had to get married even if she didn't want to.
She was so miserable that she married in the border area. She originally thought that she would never fall in love with anyone in her life, but fate made him break into her world.
