In the ninth year of Yonghe in the Eastern Jin Dynasty, Ma Wencai, a young man from an aristocratic family, drank poison and committed suicide on his wedding night. He was unwilling to die - he hated Zhu Yingtai for refusing to submit to Ning Huadie, and even more hated himself for becoming a puppet of a feudal marriage. A ray of obsession has been trapped in the netherworld for thousands of years, witnessing the wars of the Tang and Song Dynasties, the rise and fall of the Ming and Qing Dynasties, and the soul attached to armor, celadon, and blood books wandered around until an archaeological excavation in 2026 broke the seal. When he opened his eyes again, he was back in the wing of the academy where he had been when he was sixteen years old. The cicadas chirped outside the window mixed with the scent of ink, and on his desk was a recommendation letter for enrolling in Yishan Academy tomorrow.
