So apparently from the next chapter, it is revealed that the rest of the kamidogu are different colored daggers as well, each of which have tasted the blood of the One Being and its essence lives within them, and Raiden plans to use their combined force to try and contain Shinnok. Raiden as we know, entrusted one of them to Hanzo, but did not foresee what it would do to his 2nd clan. Raiden sent Sub-Zero to get one of the other ones, and after the fight between Hanzo and Raiden, Raiden came to his senses and then healed Takeda, and all three of them are on their way to find Sub-Zero now since he was never heard back from.

I guess it pretty much confirms now that Shujinko's quest of collecting the kamidogu was retconned.
