Transmigrated as a Farmer's Step-sister in a Book, My Big Brother Bosses are a Bit Pampering

When her mother married for the second time, she gained a villainous stepbrother. When her mother married for the third time, the male protagonist became her stepbrother, along with a pair of cannon fodder step-siblings—an elder sister and a younger brother—who were destined to die young. As a piece of cannon fodder, her mother spent every day frolicking in front of both the villain and the male protagonist, unaware that those two had already arranged hundreds of ways for her to die. To survive, Qin Huiyin decided that she must cling to the male protagonist's thigh, but she also had to cling to the villain's thigh. By attacking from both sides, she might actually manage to grab onto a thick thigh. It was just that both the grassroots villain and the grassroots male protagonist were so difficult to raise; trying to nurture them was truly life-threatening. Later on, looking at the villain, the male protagonist, and the originally short-lived cannon fodder step-siblings whom she had raised to be plump and healthy, Qin Huiyin prepared to retire in glory and hide her achievements. As the richest woman under heaven, she wanted to find an ancient young gentleman to be her live-in husband and reach the pinnacle of life, but as it turned out... All the matchmakers in the capital closed their doors to her. Damn it! Throw money, she must throw money.
