When Bai Yu was invited into Bai Shan's room, Manbao was giving them acupuncture treatment.
They lay on the bed, with charcoal burning in the room—it wasn't very cold. They had needles inserted in their heads and their eyes tightly shut. There were no visible injuries on their faces, but they appeared to be seriously ill in their prone positions.
Zhou Silang followed behind and immediately said, "Lord Bai, as you can see, Shanbao and the others are really injured, and quite severely at that. Even though it doesn't show on the outside, their injuries are internal. Look, look, there's even bruising inside their heads, and we can only relieve it by using acupuncture to dispel the stasis."
Bai Shan and Bai Erlang just kept their eyes tightly shut.
