Traveling through the Republic of China, I became a small cultural relic restorer in Shanghai. Immortal swords and steam locomotives run side by side, and demonic pawnshops purchase mortal souls. When I discovered that this world was actually a testing ground for advanced civilization, and that all practitioners would eventually become energy batteries, I decided to use mechanical engineering to rewrite everything. The rotation of gears replaces hand-knotting techniques, and the calculation of the differential engine replaces the deduction of heavenly secrets. Joining forces with foodie Feng Shui masters, we are not trying to defy heaven and become immortals - but to build a "lie machine" that can deceive the gods' system and steal a real future for this captive world.
