Duke Yoroc was very frustrated.
According to the plan, the Nais Clan could have taken the succession right of Falling Star Kingdom and reclaimed the Roman Sword in one fell swoop.
But now, the situation was a mess due to the death of Prince Henry, which had firmly pitted them against the king. If they were not careful, even the Nais Clan, which had intended to stay behind the scenes, might be forced into the open.
And as for the Roman Sword, that was even worse. What could have been a successful negotiation to reach an agreement had ended up angering the other party!
From a factual standpoint, cooperating with Count Castel and choosing her to sabotage the Roman ceremony might have been somewhat ill-considered, but it was still within a controllable state.
On the side of Moon God Island, however, they had completely bankrupted the entire plan!
Thinking about this, Yoroc was so angry he couldn't stand it.
