Liangyu used his dagger to cut open his sleeve and saw that a copper bullet had lodged into the flesh just above his shoulder blade. The bullet hadn't penetrated deep, with only a small amount of blood seeping out around it.
The muskets of Europa are known for their formidable power, typically killing upon impact.
