Two massive Black Jade ruins are located in Swamp City and many of their secrets remain hidden even after many years. In Swamp City, players will find the Swamp City Mansion, the headquarters of the head of Baihu's Life Guard and its associated institutions. As the residents of Swamp City face the harshest conditions and struggles, the government here has extremely important responsibilities. Among the important places of Swamp City are the streetcar terminal, which is responsible for transporting resources and personnel to and from Swamp City, and the Yuheng Department, which has played an increasingly important role in recent years thanks to its tactical leadership in the fight against darkness.

Wanderers can also look forward to a brand new boss and story in the 3.3 update. Xingtian, a well-known and high-ranking darkness, appears along with Swamp City. Capturing her in the dungeon has taken many casualties, and now wanderers have a chance to go up against her in battle. Wanderers can also experience the new main story, Swamp City at Frost, where they help Swamp City rid itself of darkness and speed up the modification of the Infinite Sundial.
