After Binding a Godawful System, I Won by Slacking Off

She was born of humble origins but had sky-high ambitions. She was determined to become the Crown Prince's consort, and dreamed of one day taking the phoenix throne. With careful planning, she pulled off a masterstroke at the imperial selection and became the most celebrated beauty in the capital. That very night, she was assassinated in her chambers. The killer was unknown. When she opened her eyes again, she had been reborn five years before the capital's imperial selection, with a spiritual wood System. Using the System, she could sense plants' joy and sorrow to judge whether something before her was good or bad, helping her avoid many dangers. But when she began plotting for the phoenix throne again, the spiritual wood System stopped working. Sometimes it could only predict half the joy and sorrow, and sometimes it got them completely backward. What a rotten System! She decided she simply wasn't destined for such a life. Heaven didn't want her to enjoy that kind of wealth and status. So she abandoned her former ambition and found new ways every day to lie low and stay alive. She never left the house, tending flowers and plants, playing the zither, and painting. She skipped banquets and stayed out of sight. When she couldn't avoid going, she made a point of arriving late and leaving early, becoming a cautionary tale in the capital. Before the Crown Prince's selection, her father obtained an imperial decree granting her marriage to a suitable match. She chose Prince Duan, an easygoing prince with no ambition. The emperor paid him no mind, and the court officials didn't curry favor with him. Best of all, he had no heirs, and the three women in his household never fought over anything. Hehe, she happily waited to marry into Prince Duan's residence and keep living a carefree life. On the night of the Mid-Autumn Festival, someone tried to kill her again! Heavens, staying alive is so hard! A servant said, “If Prince Duan breaks off the engagement, you'll have to attend the Eastern Palace's selection!” She gritted her teeth. “Break it off? Impossible. There's no place better than Prince Duan's residence to lie low and stay alive!” She peeped at him drilling his troops from the rooftop. A thousand alpacas galloped through her mind: “I thought we agreed I'd marry you and we'd lie low together!” The rotten System: Its malfunction was caused by the transmigrated rival who knows the book's plot. It now begs to be accepted as its master again. She: “Do I have a rival?” He: “Kill the one who came for your life, and you'll stay alive, won't you?”
