Where was the repeating crossbow invented?

The repeating crossbow, also known as the "Zhuge crossbow," was invented in ancient China during the Warring States period, around the 4th century BCE. It featured a mechanism that allowed multiple bolts to be fired in rapid succession without reloading after each shot. This innovation significantly enhanced the effectiveness of crossbow warfare in Chinese military history. The design later influenced crossbow technology in other cultures as well.
