In a year of severe drought, the Liu family in Liujia Village, Qingzhou Prefecture, was falsely accused of being a bandit because they offended Li Zheng, and their home was confiscated and expelled.
The three-year-old granddaughter Liu Ya'er is gifted with the ability to read minds and can hear what people around her are thinking. She is also blessed with good luck, turning misfortunes into good fortune and disasters into good fortune.
On the way to escape from famine, Nai Tuanzi relied on his mind-reading skills to detect in advance bandits' ambush, poisoned water sources, and unpredictable people. Nai Tuanzi reminded his family time and time again to avoid disasters in a "childish way".
Passing through Qingshan Pass, the king of Zhenbei, Xiao Yu, led his army to station, and overheard the voice of Xiao Nai Tuanzi - not only could he read other people's minds, but his sentences were also efficacious and his every word was sharp.
Xiao Yu took the Liu family under his wing out of curiosity and profit considerations, and the Liu family has been on the rise ever since.
The whole book is based on the main line of "escape → settle down → take root → start a business → enter Beijing → be crowned", interspersed with the growth and marriage lines of the Liu family, and using Xiao Yaer's good fortune as a hidden thread to connect all events.
In the end, the main plot ended with the situation in the court being calmed down, the Liu family being full of glory, and Ya'er growing up to six years old and sitting on the ridge of his family's hundred acres of fertile land, holding a candied haws in his arms and smiling until his eyes were crooked.
