Staying up late transmigrating into a book, opening one's eyes to become a short-lived cannon fodder, inner complaints all heard by the master and three senior brothers. The scheming female supporting character relies on the system to steal luck, sequential poisoning to seize opportunities, each time poked through on the spot by the heroine's inner spoilers. Subduing the ancient phoenix in the secret realm, the villain suffers thunder retribution from multiple tasks, and also bewitches the fourth senior brother to be the demon lord's container. The heroine finds the dragon soul sword restraining the demon lord in advance, the eldest senior brother born with sword bones, the second senior brother with true phoenix bloodline, the third senior brother holding a divine sword, the three joining forces, slicing and destroying the demon head with one knife, directly counter-attacking to become the darling of the heavenly way group.
