The reason why P5092 said the two snipers were very powerful was because the two seemingly simple shots were not simple at all.
First of all, the frontline commanders were unable to confirm the snipers' location even though they had covered a very large area during their carpet search. If so many people could not even confirm the snipers' location, then the snipers would have to be at least 900 meters away.
At a distance of 900 meters, both shots had landed right on the barbarians' chests and killed them. This was not something that just anyone was capable of.
After all, the two barbarians had stayed hidden all this while. From the moment they appeared to the moment they swung down their axes, it took only a split second. Meanwhile, the snipers had to immediately calculate the trajectory of their shots after discovering the barbarians when they showed themselves!
