Her Character as a Sickly Daughter Has Collapsed Again

The system taught me to be green tea. Who would have thought that the pitiful eldest daughter of the Li family, who looked delicate, frequently vomited blood, and fainted from time to time, could kill without blinking an eye, and was equipped with various killing skills such as close combat, tracking, and poisoning. Who is not the reincarnation of a killer? It's just that this system only teaches people who are cute and pitiful, coquettish and beautiful, weak and boneless... Oh my God! Let me cut you guys into pieces!
