Tian Doudou transmigrates into a book, becoming a doomed cannon-fodder character in a period novel. All she did was complain about the plot, and suddenly she was in the book. She wasn’t the heroine or even a supporting character, just a minor cannon-fodder character who died young. Tian Doudou thinks life is just too hard. Every day feels like a year. She has to do housework despite being so young, and the food is truly hard to stomach. There’s no meat, and she can’t even get a bowl of plain white rice. What’s more, she transmigrated without a single golden finger. Every day feels like a year. Then one day, her grandma gets into a fight with someone, takes a blow to the head, and passes out. When she wakes up, everything has changed… Thanks to her grandma’s hard work, Tian Doudou finally becomes a dazzlingly wealthy third-generation heiress!
I feel like I haven't written a lot of it.
To put it simply, the heroine has traveled through time, but there is no golden finger. Grandma is reborn. Grandma is the biggest golden finger of the heroine and the whole family.
