As Nanli had anticipated, stepping through the archway felt like entering a cold, dark underworld. Dense black mist guarded the area, immediately attacking from all directions upon sensing their presence. The fire talisman extinguished in an instant, and the eerie howls of the black mist added to the terrifying atmosphere.
Nanli swiftly drew her Dark Moon Sword and swung it in a graceful arc. The sword's blade glimmered with golden light, crackling and sparking as it cut through the mist. Despite her efforts, the black mist continued to swarm, attacking in relentless waves.
Realizing the futility of battling the mist head-on, Nanli used the Heaven Star Brush to draw symbols that cloaked her and Ye Siheng, concealing their presence. The black mist hesitated, unable to locate its targets, and soon dispersed.
