After a top modern assassin dies, she travels through time to become the ancient orphan Hu Feier. The original owner was abused by a vicious grandmother and nearly sold, hitting her wall and nearly perishing. Feier, after rebirth, is mature in mind, using her combat skills to tear apart extreme relatives, and smoothly divides the family under the village chief's witness. She enters the mountain to hunt, unexpectedly awakening the spiritual spring space, relying on spiritual medicine and game to exchange for silver, doing business, buying land, and building houses, pulling her younger siblings along to study and practice martial arts. Along the way, she rescues the assassinated noble young master Murong Jin, and the two support each other and grow fond of each other. She punishes the villagers who spread rumors and do evil, relieves and supports the neighbors who help their own family, and uses self-made healing medicine to open up the sales channels for medicinal materials, finally settling down and building her career, waiting for the returning Murong Jin.
