When Wang Yi, a doctor of science and engineering, woke up after his death, he found that he had become a cat and was possessed by Wang Zhenyi, a female scientist from the Qing Dynasty.
The lifespan of a cat is only more than ten years, but Wang Zhenyi herself only lived to be twenty-nine years old.
She decided: Instead of being sad about the spring and autumn, it is better to use this limited "shared life" to realize the unfinished experiments, unfinished papers, and unpromoted scientific knowledge in this ancient time and space.
Purpose: Wang Zhenyi still passed away at the age of twenty-nine, but left behind scientific works that were more systematic and widely disseminated than in history. The cat "Xue Tuan" died peacefully on the day Wang Zhenyi died. In a modern museum, when a young researcher was sorting out Wang Zhenyi's manuscripts, he found a well-preserved white cat hair in the folder, with beautiful small words next to it: "My friend Xue Tuan is also my teacher."
