Iron Skill Bone is sneakily sending messages to Bone.
Mo Hua is standing right behind him, leaning in, silently watching him chat with Bone.
This isn't the first day Mo Hua has done this.
Lately, Mo Hua often spies on Iron Skill Bone and Bone's "private chats" at midnight.
The "Letter Token" they use for private communication is a special bone shard.
Iron Skill Bone uses blood to write on the bone shard; Bone on the other end can receive the message and reply to Iron Skill Bone.
Originally, this Bone Book Order did not belong to Iron Skill Bone.
But ever since Mo Hua differentiated and formed an alliance with the Shugubu, improving relations between the Shugubu and the Danque Tribe, their relationship has eased, and they've been in contact.
Iron Skill Bone must have secretly "met" with Bone at some point, reached an agreement, and exchanged Bone Book Orders for private collusion, secretly transmitting messages.
