Deity-binding nets are expensive magical tools capable of trapping gods, demons, spirits, monsters, and humans. The golden threads are thin, but difficult to break except when a weapon or tool of superior spiritual power is used on them.
Jiang Cheng purchased four hundred deity-binding nets and set them up all over Dafan Mountain to aid Jin Ling , but all four hundred were broken by Lan Wangji, who considered such an act as going against the rules of night-hunting. The rural cultivational clan that Wei Wuxian met on the way to Dafan Mountain fell into the nets' trap twice. Although Jin Ling refused to release them after the second time, they were ultimately freed by Lan Wangji's sword, Bichen.
