Do you expect them to clash and have another few chapters of fighting. Or will Shin end this here since he is on a time constraint and needs to end the battle quickly? It could end this chapter or in a few chapters, but my thinking is that the Han army is going to lose moral and quit fighting like the Wei army did once their Generals are defeated. It won't be like what Ri Boku said about Qin losing Ou Ki during the Battle of Bayou.
Do you recall the Buddha fight? I think we're in for something similar, with the chapter opening on Shin winning the clash and cutting down Haku.
idk what follows that, but I am increasingly more confident in a) Haku surviving, and b) Shin being the reason why.
In my mind, this plays out with Shin cutting him down and then loudly calling for the medical unit, i.e. Saki clan, to show up and show out with their medical expertise.
I think such an act, combined with the Nanyou stones (

) could take the fight out of Han. Even more so if Haku is still conscious to speak with Shin - likely within earshot of his vets and lieutenants.
Shin pacifying the Han could then result in Raku losing very quickly. Yoko might retreat back to his position if necessary, but I would prefer Kyou Kai kill him. It's been 500 chapters since she killed anybody that was a somebody in terms of martial ability.
