The universe is a guesthouse for all living beings, and time is a traveler from the past to the present. The difference between life and death is like the difference between dreaming and waking, ever-changing and unfathomable. What awaits us beyond life and death, beyond the universe, outside the flow of time? This is the sixth long novel by Er Gen, following 'Reversing the Dao', 'Seeking Demons', 'I Want to Seal the Heavens', 'Eternal Thought', and 'Three Inches of the World'.
