Song Jian sighed, looking at the thirty-odd blank sword stones on the table, pondering what kind of city defense sword formation he could create with these stones.
If he was using it himself, these thirty-odd sword stones would be enough for Song Jian to use for a few months. However, if they were used to set up a large formation for city defense, he could only create a sword formation that could defend a single city gate at most. This would only increase the defense of the city gate by a few thousand degrees. When compared to the defense of the entire city, it wouldn't be much use.
"The task of ten thousand defense units is merely a baseline, utterly insufficient. If we want the city defense to be easier, we need at least two hundred thousand, or even three hundred thousand defense units!" Song Jian gritted his teeth.
