Understanding the Lung race
Lung characters draw from East Asian dragon mythology, featuring antler-like horns, serpentine tails, and sometimes whiskers or scales. They differ from Vouivre dragons and hold historical prestige in the Arknights lore. Chen Qianyu embodies these traits as a disciplined martial artist from Endfield Industries, trained in Chi Xiao swordmancy.
