The speed of arrows was extremely fast and also from a tricky angle. Even though it was shot straight from the front, the trajectory of the flight was through a crowd of players. Under the cover from the other players, only a person like Wang Yu who could sense danger would be able to detect this.
Shooting through the gaps between players could easily result in the death of the wrong target. However, the fact that the arrow was able to fly through the crowd of players to reach Fearless proved that the opponent's control of the speed of arrow reached perfection. The level of accuracy was also exceptional. The Archer's confidence in his own ability was also at the maximum.
Otherwise, the moment this arrow had the slightest of deviation, it wouldn't be effective as an ambush.
