Work together
Fang Tao was more than just aware of her situation, she knew that her family was nothing but a bunch of blood-sucking leeches. They would keep on clinging and sucking her blood until nothing was left in her body- after all, they have done the same thing to her sisters too. Both of her elder sisters were sold off and her mother drove her second sister to a corner until the latter had no choice but to break off her relationship with her maternal family.
Her parents had the prodigal thinking that only sons were good, thus they didn't even treat their daughters like humans. They were just a source of getting money for their beloved sons and before becoming a chip to be sold for a decent price, they all were a means of providing comfort to her brothers.
