Does anyone know anything about these chinese multiple - shot crossbows (non-repeating), I mean a crossbow that can fire 2 or more bolts simultaneously (similiar to a volley gun)? :surprised:

Here are some images. The first crossbow is called a Liannu and the other is called a Chuangzi Nu

Chinese repeating crossbow called chu-ko-nu sounds more familiar to me.
