Yang Zhenshan, holding a telescope, looked at those crossbow arrows, and faintly smiled, "The timing is still too tight, the design is not very reasonable!"
Those pieces of paper wrapped around the crossbow arrows were his own requirement.
A simple paste job was enough; there was no need for it to be too secure, and to allow the paper to fall in the air, the pasting had to be done on only one side.
Due to the rough manufacturing, these crossbow arrows had many problems, such as the paper coming off before reaching the skies above Chongshan Pass, while others remained tightly attached to the arrows even after landing within Chongshan Pass.
Although there were many defective crossbow arrows, there were also quite a few that successfully completed their mission, scattering a large amount of paper in the air.
Paper filled the sky, carried by the wind, scattering into every corner within Chongshan Pass.
