Kan Ki's personal army of 55,000 pretty much lost the entirety of their infantry force and was whittled down to probably 10% of their original number, if they're now considered less of a threat than the 10,000 or so combined remains of the HSA and GKA.
The core of Kan Ki's clans more or less escaped, but losing the Zenou clan hurt them considerably. Rin Gyoku and Koku'ou couldn't hope to compensate for that kind of fire power.
Of the 140,000 Qin troops that arrived at Gian, I reckon RBK will have buried in the neighbourhood of 125,000:
- close to 100% of the 10,000 Heki Army
- close to 100% of 50,000 Fuu Han Army
- close to 60% of 25,000 HSA + GKA, i.e. ~15,000
- around 90% of the 55,000 Kan Ki Army, i.e. 49,500
Throw the 40,000 buried by the Roumou Army on top of that and RBK has come close to repaying the Qin twofold for Eikyuu.
