This flying dagger, as thin as a cicada's wing, was personally crafted by Xu Nian using nothing but ordinary scrap iron.
However, after his repeated hammering and refining, its quality had nearly come to match that of Xuan Iron Weapons, making it the most perfect weapon Xu Nian had ever forged.
The distinctive feature of this flying dagger was its lightness, with engraved patterns that Xu Nian had meticulously designed. These patterns not only reduced air resistance but also made use of the wind force to achieve greater speed.
Although Xu Nian's Spiritual Sense had not yet reached the level of controlling a Flying Sword to kill, he could easily manipulate a small flying dagger.
As his Spiritual Sense grew, so would the power of the flying dagger, killing enemies unseen.
Xu Nian had forged a total of nine flying daggers like this but with his current ability, he could only wield one; if he were to use two, both their power and speed would significantly diminish.
