The Secret of the Silk Road

Retired special forces soldier Ling Feng reinvents himself as an archaeological expert and is tasked with finding the scattered fragments of a Tang-dynasty armillary star map.

During an explosion on Hong Kong's antique street, he sees through a fake-artifact scam and unexpectedly obtains a clue to the star map.

An expedition into Turkish caves is hit by a collapse, and Ling Feng digs a thousand-year-old bronze box out of the rubble with his bare hands.
