Before his rebirth, he was Lin Yan, the feared "Master Yan" on the road, but he was assassinated at the dock and was buried in the river; after his rebirth, he became Lu Niannian, the apple of the eye of the underworld boss Lu Zhenting, a three-year-old girl who was held in the palm of the family.
The cruelty and calculations of the previous life were all hidden in this pink and jade-carved body. In a mafia family full of guns and rules, Lu Niannian plays the role of an innocent and sweet little princess, while quietly using her past life experience to make plans - she can detect the smell of danger from the crib, and uses children's words in the cradle to remind Lu Zhenting of the hidden dangers around him. When her father was attacked and disappeared, she used her three-year-old body to stabilize people's hearts and set up a trap to fight against foreign enemies.
Lu Zhenting felt hurt and curious about this precocious daughter, but he didn't know what kind of old soul was contained in her little body. When Zhao Tianxiong, a powerful force from the neighboring province, covets the territory and his father is in danger, Lu Niannian is no longer just a little princess being protected. She used her identity as a child as a cover, and relied on the power of her father's old gang to get around. Even in her daily life in kindergarten and elementary school, she hid a secret plan.
This is the story of a reborn gangster who grew up as a young boy in a mafia family. He was protected by his relatives and secretly guarded his home and territory. In the intertwining of warmth and swordsmanship, Lu Niannian gradually moved from behind the scenes to the front of the stage, becoming the "little princess" of the Lu family who can truly stand side by side with her father and protect the world.
