Just beat this guy. I thought I would maybe be OK with him and the Ming General in Cloudspire surviving, but now that I've played it I really don't like it, it was definitely better before.
Regarding quest breaking, I skipped He Youzai completely in the Shaft. He and Fang Yao showed up in the teleport menu for being at the refugee camp now so I assume it's fine for the quest. I skipped them there though since I already have the shrine which was ahead of them unlocked. If this doesn't brick the quest in Chapter 4 then it might be possible that you can completely skip He Youzai in almost all his locations and still get the good ending.
