In the late autumn of 1933, the city of Nanjing was shrouded in river fog and gunpowder smoke.
When the code of the ancient astronomical map collides with the bloody spy,
The blue sky cracked the silk, and the paper kite held fire and fell into the river.
The ancient pictures hide the edge, and the copper box secretly attracts the stars.
A game of life and death with stars as the code,
Who can turn the bronze key hanging on the fate of the country?
The only thing that can pierce the darkness of 1933,
They are the quenched stars and the unburned hearts.
In the gaps of history, the stars are the only password——
