This is actually a bit similar to Ken Cheng's thread in the past (too bad I can't find it) about how many soldiers can a Great or the Sweeper Monk handle. Anyway, in LXF novel, XMCS threatened to team up with YGC to wreak havoc in the Forbidden City. The imperial guards were quite frightened, I guess. If they did team up, do you think they could really bring devastating destruction to the palace?
Edit: found Ken Cheng's thread Maximum number of soldiers that a great martial artist can handle
