Archy's arrows were coated with a layer of his chi which not only sharpened his projectiles but also had the effect of slightly paralysing the target. Furthermore, the rope arrow had a mechanism which opened up the moment it ledged into the flesh, causing more pain for the underling since its spikes were entrenched into the muscles.
Compared to the Nian itself, the underling did not have dragon scales, thus allowing the Panda Archer to easily penetrate its flesh. Once hit, Bu Dong and Yue Han quickly tried to pull the 'Sui Lion' as it was called on their interface towards themselves while it cried out for help.
