After the Duke's experiments, he was quite satisfied with the Breaking the Sky feature, as it provided him with an additional attack method.
The Sword Qi of Breaking the Sky not only had an intense slicing ability but also contained explosive energy bursts, making it a powerful attack method.
More importantly, it filled the gap in the Duke's mid-to-long-range attack repertoire, as he previously could only resort to long-range attacks with a bow and arrow.
However, bows and arrows were easy for Knight-level experts to defend against, and rarely yielded good results.
Typically, by donning full-body armor, one could essentially ignore the threat of ordinary arrows.
But the Breaking the Sky Sword Qi was different; ordinary armor could not defend against it, and if hit, it would cause severe injuries.
Subsequently, the Duke conducted further testing and concluded that the effective attack range of the Sword Qi was thirty meters.
