As far as the thousand blades sect's disciples were concerned, even Foundation establishment stage disciples with average aptitude could control more than a dozen weapons at the same time. If their aptitude was better, it wasn't impossible for them to control dozens of weapons at the same time. However, it was very difficult for them to improve after that. When they reached the level of the nascent Soul Stage, they could generally control a hundred weapons at the same time at most.
Lin Yi had only briefly studied the thousand blades sect's practitioner's Arts, but he knew where the difficulty lay-the biggest one was multitasking. Controlling each weapon required a part of one's focus, and it was hard for normal people to do two things at once-to control a hundred weapons at the same time required a hundred things at the same time. It was an inhuman level of difficulty.
