Soul and body split, tour cosmos
In Xu Nianci's 1905 tale, the boastful narrator is caught by a violent force on a high mountain, and his soul is torn from his body. The soul drifts into space, visiting planets such as Mercury, where it sees inhabitants performing brain-replacement surgery, while the body falls through the Earth. The two halves have separate adventures before the narrator returns to China, recounting fantastic pseudo-scientific wonders as sober fact.
