That was ... almost anticlimactic with how silly everything around it is. (Just how deep is that river? How long was Yu submerged? Apparently long enough for Ruantao to make eventually abandoned rescue attempts, all while the Emperor waits for diner? Can anybody even swim in those clothes to begin with? And how much blood do you need to lose in a running, disturbed stream?)
Plus, there is still a chance the Emperor finds some weird excuse that Yu'll eat up, as she did the last times.
