Ning Sheng, an inhuman being with a lifespan of three hundred years, developed a desire for the "human heart" after seeing the warm life of the Lin brothers and sisters on a rainy night. He moved next door to the Lin family under a pseudonym, and gradually integrated into the lives of the brother and sister in the name of learning swordsmanship and reading. After receiving the "heart stealing" technique taught by his old servant Ji Bo, Ning Sheng created many "heart-stealing" incidents in the city in order to verify this method...
This joke is probably an extension of a dream I had after reading Hua Xin.
Concept: Human nature is not a static heart, but a flowing light that can be extinguished and rekindled.
