He is a human who lives in one of the kingdoms within the Wu Li Empire, and since he is the boss of the mercenary group, he assigned three people to do the job instead of doing it himself. The three men who received his orders were werewolves, and they were formerly soldiers in Dong Lang. Several years ago, the three men were left behind when Dong Lang soldiers went on a dangerous mission in one of the forests.

The person who had saved them when they were in danger was Hong Cheng, and that was why they had agreed to cooperate with that man in the Moon Behind the Clouds.
