THE KING!?!! DOES HE MEAN JIN WOO OR AOTHER PERSON/THING!?!!

SPOILER
That statue ( the architect of the system) is trying to "resurrect"(but he is not dead though) the Shadow Sovereign into Jin Who's body.

SPOILER AGAIN
In the future the Shadow Sovereign will give up his life and give all his powers (including immortality) to Jin Woo so that he can "carry on his legacy".

Ps: I don't know if it's understandable because English is not my first language, so sorry (〜￣△￣)〜

as a person whos first language is English i can say that it was very easy to understand what you were saying and thank you for the information
