Someone actually leapt down from the rooftop beside the road, and their target was none other than the emperor's carriage, parked right in the middle of the street!
Due to Emperor Yingzong of Qi's need for a low-profile escape, he did not take the city's main roads, and the street was already quite narrow. As a result, when the person leaped down from above, they were less than ten meters from Emperor Yingzong's carriage.
Ten meters, by all accounts, was still a very difficult distance to succeed from.
On the ground, whether using crossbows or any other ranged weapons, they would be blocked by the guards putting their bodies on the line.
While in the air, it was hard to guarantee the accuracy of arrows or crossbows.
Moreover, the emperor was behind layers of curtains within the spacious carriage, making it very difficult for a single arrow to accurately pierce the window and strike a vital spot.
