Ever since Dayu controlled the floods and split Jade Huang, Ye Xuan has been carrying his destiny and wandering through the rifts of five thousand years of history. He saved Bigan Liu's seven-qian ren coin to prove the corruption of the Yin Shang Dynasty, helped Sima Qian to save the Blood Prison Bamboo Slips to record the secret history of the Huns, and even mixed the hallucinogen with meteorite fragments into the tattoo of the word "loyalty" on Yue Fei's back, laying a tragic foreshadowing. And Xiwei, the daughter of the Tushan clan, follows her like a shadow: rubbing the "Book of Mountains and Seas" on the floor tiles of Afang Palace, verifying the list of regicides on dragon scales on the wordless stele, deciphering the African pottery pattern navigation map of Zheng He's treasure ship - she traces Ye Xuan's footprints across time and space with historical writing.
Ye Xuan intervenes in history with weird humor: he gave Li Bai a magnetic levitation jug to fish for Sui Yang Emperor's Shen Yinjing, but he was drunk and chanted "You don't see the water of the Yellow River coming from the sky"; he persuaded Du Fu to open a thatched cottage B&B, but was written in "Song of Thatched Cottage Broken by the Autumn Wind". The jade emperor's carvings became more dense as the centuries went by: **The collapse of rites** (Zhou), **Feminism** (Tang), **Greed and delusion** (Ming)... When the carvings reached 99, the salt pillars by the Humen Burning Pool condensed into Lin Zexu's tearful admonishment (Chapter 98), and Ye Xuan finally gathered the glimmer of humanity needed to mend the sky.
