After Marrying the Number One Villain, the Emperor's Adopted Daughter Was Sentenced to Death in the Palace

[Sweet pet + Marriage first, love later + Highlights for all members] Cannon fodder princess? No! He is a top undercover! Shen Qingnian, who lost his parents when he was young and was adopted into the palace, just celebrated his 20th birthday. When he woke up, he found that he had become the "best candidate" for marriage to the Gu family, a wealthy family in Jiangnan. In the name of marrying into a rich family, in reality, she was asked to be the sugar-coated bomb to investigate various crimes of the Gu family. "If you succeed in taking advantage of yourself this time, you will be a hero in the world." As long as we find conclusive evidence, we can justifiably capture the Gu family and improve the livelihood of millions of people in the south of the Yangtze River! Shen Qingnian's blood boiled with enthusiasm and he saluted the emperor and empress: "Everything is for Daliang!" Taking on the task of marrying into the Gu family, Shen Qingnian originally thought it would be a hellish level of difficulty. Unexpectedly—— Her husband, Gu Jinxuan, was handsome and gentle. He took off her hairpin with his own hands every night, doting on her to the point of no principles; Brother-in-law Gu Chengxuan was frantically handing over the list of black materials, fearing that she wouldn't check it fast enough. This is too smooth... Shen Qingnian was thinking hard about a bunch of clues, and accidentally touched the lines on the longevity lock, and was suddenly startled into a cold sweat—— It turns out that what she is investigating is not a case, but the ups and downs and bloody events of more than 20 years ago. It turned out that she was not marrying a man, but an ally whose family was massacred.
