The blueprint was unfurled, revealing the design of a cleverly crafted crossbow arrow.
The crossbow depicted on the blueprint was completely different from ordinary ones. Not only did it lack the conventional crossbow mechanism, but a large wooden box was situated above the usual arrow slot, with a protruding lever positioned at the rear of the box.
In addition to the overall design, the blueprint also included detailed breakdown illustrations.
As an industry expert, Huang Lao quickly grasped the blueprint's intricacies and deduced the purpose of this crossbow arrow.
Upon raising his head again, Huang Lao's eyes were filled with astonishment: "Young friend, can this crossbow perform continuous shots?"
Huang Lao's voice trembled slightly as he spoke.
