Please help me find this novel. I have been searching for a really long time. The female lead is reincarnated into a book as a child. She escaped from the mansion after growing up but gets kidnapped and ended up married to the male lead. The kidnappers were then who did not want to marry their own daughter to the male lead were killed by the bandits, so the family had to take care of the funeral at the start of the novel. Female lead uses her modern knowledge to come up with novel things. I think she also has a space, not sure. Then, her husband goes to the imperial examinations. She develops her business. The emperor is kind and intelligent. When she is framed one time, she uses her space to make the weapons in her shop disappear and escaped. She also helped the eldest brother in law to become a kang builder and second brother in law to become a carpenter.
