The people going to the castle this time were all heading into extreme danger. Everyone the Nie Family had stationed there was fully armed and battle-hardened. Mystic Doctors might not be completely helpless, but compared to those people, they basically had no chance of winning.
The people from the Modern Families didn't realize how high the level of danger was at the time, while the Ancient Families assumed that since they were of the same Ancient Family lineage, the Nie Family wouldn't dare make a move on them before things were settled.
So if Beisitian and Luo Xudong hadn't joined forces, both sides' troops would likely have been caught off guard, with a very high chance of total annihilation.
