"Rebirth and counterattack" + "combination of medicine and poison". The heroine no longer just wants to win the house fight, she wants to become the "Da Vinci" who can save the world and change the medical environment from the root. She combined the "poisoning/detoxification" experience accumulated in the backyard of the palace in her previous life with the pharmaceutical technology she systematically learned again in this life. Her house fights are no longer superficial fights, but she uses "medical behaviors" such as acupuncture, massage, and diet therapy as means to quietly control, influence, and even eliminate her opponents.
