It's a historical manhua. All i remember is that the female lead has some divine premonitions or some type of fortune teller powers? And because of this her family saw her as a bad omen and offered her as one of the emperor concubines?, (but nobody really knew of her powers until she tried to beg the emperor no to do something in order to save his life). She clung onto him to warned him and gave him a talisman, this is how she got his attention. She's also not really interested in winning favors for the emperor, instead she rather be a salty fish/just eat and has a small garden farm on her palace (like raising fish, chicken and vegetables). But the emperor starts liking her because he sees her as a woman who doesn't carry ill will against him or is trying to win his favor like his other concubines.
Sorry this all i can remember, but I'll be extremely grateful if someone can help me find this manhua that i forgot to save to my reading list T.T
