It makes sense if we assume Zhao and Qin are still close in military might (Even though Qin’s military is united under Sei while the Zhao military are split because of their King)
Imagine Zhao invading Qin, and Qin wasn’t defending themselves from other states like Wei and Chu as they are now. The Zhao would have to find a way around Ousen, Kanki, Yotanwa, Moubu, Tou, as well as the new Qin Trio now, and even before the new trio they’d have had Duke Hyou, Mougou, and Choutou to fight.
And the Zhao wouldn’t have been able to invade with their full army either, at best only around 60% or so of their army could invade or else they’d leave themselves open against attack from behind.
What I’m trying to say is, I think it makes sense that the Qin has struggled as much as they have. The 100K elites of Kantan under Kochou probably have very capable commanders under them in addition to Kochou.

My point was these 3 same Generals that presently got occupied by Zhou for a year, will Later on (with Tou maybe) defeat Zhou at it's best i.e Riboku, Shi Ba Shou and new allies that former talked about. That underwhelms Riboku n Shi Ba Shou.
More so, RIboku whose character highlight in itself is of Great General who stood as the Biggest Wall between Zhou and Qin victory, if not entire China Unification. But here they doing just fine on their own without Riboku, while former suffered a loss before.
Anyway, Hara never fails to deliver. He might have a solution for this, maybe Qin will almost annihilate Kantan Royal Elites, or Wei Generals will help later on. But one thing is clear we have been underestimating Zhou Kantan Elites forces.
