A modern Northeastern girl transmigrates into a discarded concubine in the Cold Palace and binds a system! Facing mad concubines who wail and vent resentfully at night, she doesn’t rely on palace scheming or cruelty; instead, she uses Northeastern song-and-dance duet to relieve stress and heal hearts. When she meets a Cold Palace eunuch drowning in workplace burnout and bullied, she gives online lessons on survival rules for workers and counsels him in all sorts of ways. From then on, the Cold Palace says goodbye to misery—every day is iron-pot stew and chatting, and everyone gets a comeback and healing!
