A murder case. A fractured frontier. A path back to Chang'an.
Year 863. Zhang Yichao has retaken Liangzhou after a brutal campaign, but Hexi remains a land of old wounds, competing loyalties, and unfinished reckonings.
For nearly a century, this frontier has stood cut off from the Central Plains. Yet even here, people still raise the banner of return. What are they truly fighting for - home, power, survival, or a memory that refuses to die?
Longing for Chang'an begins with a single murder and unfolds into a historical mystery shaped by investigation, political maneuvering, and branching choices. Gather clues, expose lies, weigh factional interests, and decide how far you are willing to go. Each deduction reshapes the people around you; each choice leaves its mark on the fate of Hexi and Beiting.
