Time Travel: The True Heiress Has a Pinduoduo System

Jiang Yuan and Pin Xixi transmigrate into a historical novel they've read, becoming an orphaned girl who is bullied and the male protagonist's blood bag.
Jiang Yuan, who had just transmigrated and was immediately informed that she would be engaged in three days: What the heck?!
The original owner's wife ran away to her old husband who had four elderly parents and four young children. Let whoever wants to marry her marry him. She doesn't want to be a mother without pain. She wants to go to university and go to the capital to trample the awful male and female protagonists under her feet!
[This story is set in a completely fictional world.] [If you criticize the female lead, you can't criticize the author.]
