The Princess Is Not at Home

She was an eccentric girl who was good at inventing and making all kinds of weapons. She was rumored to be the third lady of the prime minister's house who was extremely ugly. She married Lord Shura Feng Tianmo and was thrown into a side courtyard without even being worshiped. Don't want to see her? It doesn't matter, she sneaked out of the palace and had a great time. Making a magic weapon? That's her specialty. Accidentally, she became the "ghost hand" that the various forces in various countries and martial arts factions wanted to win over. Her husband, the ruthless Prince Shura, wanted to divorce his concubine, who was herself, and marry her again? Does he know that she is the one he has long forgotten?
