Which crucial outcome resulted from the early Chinese mastery of the investment casting process, when producing complex bronze crossbow trigger mechanisms?

💡 Explanation

Investment casting enabled precise replication of complex shapes with tight tolerances; therefore, standardized parts led to reliable triggering mechanisms, rather than merely reducing material costs or directly improving aiming, because the manufacturing process was more standardized.
