As the only "New Humanity" researcher in the Dajing Dynasty who relied on staff for a living, Yunqi's daily life consisted of drinking tea, reading newspapers, and writing some fishing reports on "Why New Humans generally have one extra toe than ordinary people" while waiting for retirement. Unexpectedly, with a transfer order, she was "assigned" to guard the newly discovered relics of the former dynasty in the suburbs of Beijing.

Yunqi (adjusting his non-existent glasses): Don't ask, asking is science. This is a story about how knowledge changes destiny and turns the cold-faced King of Hell into a loyal dog and fanboy. Others rely on supernatural powers, but I rely on mathematics, physics and chemistry to travel around the world. Lu Yan: Master Yun,
