Are the Three Siblings Villains? It's Okay, Get on the System!

[Travel time + farming + system (not many scenes) + raising children (younger siblings)] Liming Yue traveled through time and became the eldest sister of three villains in a book who died young. Their parents died young. In order to support her three younger siblings, this eldest sister sold herself to a wealthy family as a slave. She was later tortured to death and her body was hung at the door of the house. This was the beginning of the gloomy path of several minor villains. Liming Yue was lying on the rickety wooden bed, looking at the thatched roof that leaked wind and rain, and even the stars could be seen in the middle of the night. Next to her were the cries of three little villains waiting for food. She clapped her hands and sat up suddenly, no! I need to make money to support my baby! Then the last large piece of furniture in the house—the rickety plank bed—collapsed. Through continuous efforts, the eldest brother became a young and promising general, the second brother became the number one winner on the gold medal list, and the younger sister became a shrewd and capable businessman. When Liming Yue saw that the three children had finally taken the right path and were about to let them go without any worries, a certain dishonest grandson of the emperor came up and said ambiguously: "After taking care of the three of them, it's time to settle the score between the two of us~" The male protagonist who looks dignified and polite but is actually cruel and sultry VS the female protagonist who is smart, kind-hearted, brave and resourceful but not brainless and kind.
