In the age of rebellion when gunfire and salty winds intertwined, Qin Lan used a forged military medal to navigate the rifts of power. She is not an ordinary treasure plunderer, nor an adventurer favored by fate - but an exile wanted by both pirates and revolutionaries. The legendary sunken ship "Night Crow" is said to contain relics that subvert the secrets of the empire. Whoever can find it can reshape the troubled times. Qin Lan embarks on a journey of pursuit. Her motive is not greed, but the last clue to find her missing relatives. However, she forms a sinister alliance with a rebel leader, a disgraced noble, and a cold-faced sailor at the edge of the deep sea. Every betrayal comes like a tide, and every piece of gold and silver hides a broken oath. The mystery of the shipwreck is not only about treasure, but also a purgatory of faith and loyalty. Qin Lan must rebuild himself in the cruel struggle, or be swallowed by darkness. This book depicts the struggle and redemption of marginalized people with life-threatening writing in the storm, making every page impact the soul like artillery fire.
