It's true that Li Yunzi does not get along with Nan Lingsha.
As for Nan Yuso's relationship with Li Yunzi, it seems a bit elusive.
On the surface, Nan Yuso calls Li Yunzi 'sister' this and 'sister' that, but she seems to always be opposing her covertly, though it's mostly over minor matters.
"Where are you hurt?" Li Yunzi gently supported Zhu Minglang, noticing that he appeared exhausted and weak, his complexion pale without a trace of color.
Zhu Minglang exhaled a breath of air that turned to frost. He glanced at the city wall with lingering fear and said, "I just feel a bit cold. I can't seem to warm up."
"Yuso," Li Yunzi turned back to look at Nan Yuso who was holding the Immortal Rabbit Dragon, signaling her to let the little Chang'e help Zhu Minglang dispel the ghostly chill in his body, "heal Minglang's injuries."
