Chapter 148: Fishing In Troubled Waters
There were several methods for a siege.
One of them was called a Xue.
It involved digging a trench directly under a castle wall, installing a bomb, and detonating it to destroy the walls' foundations and collapse them.
After all, if one couldn't break through the main gates, one could simply break through the wall next to it and enter through the space created.
However, the Xue was a siege method.
In other words, it was a method only used by imperial government troops, who were accustomed to sieges and defensive fortifications. This wasn't something used by those of the murim.
To begin with, the concept of siege or defensive fortifications itself was unfamiliar to them.
Neither the Nine Sects and One Gang nor the Five Great Ancient Families, or any sect or family for that matter, had anything like a fortress in the first place. Moreover, if they were to construct something like that, the imperial government would likely suspect them of treason and send troops to investigate.
However, there were some who still had this knowledge that was buried within the murim.
