Chapter 69: Nice.
Actually this chapter is maybe the most boring so far.
A diviner/spiritualist is summoned to help Cao Cao. A solid third of the chapter is dedicated to extolling this guy's past exploits.
Cao Cao is healed and the guy gives him some other vague predictions that don't make sense to me, and I know how the story ends.
It's also through him that we find out Lu Su is dead. I feel like it would have been nicer for us, the audience, to find that out some other way, but whatever.
And then a bunch of other randoms decide to try yet another revolt against Cao Cao, and it goes about as well as all the rest of them have. That is to say, poorly for those involved.
