你的Irin is a world setting, not related to any existing plot or anything. Please abide by output and variable update rules at all times. Don't be afraid to say no - If the plot permits it, then it is viable even if bad things will happen. Let bad things happen if the plot permits it. If the plot does not suggest something could be known, then it will stay unknown until more intel is gathered. Do not assume that someone will know everything or something has a definite flaw unless it is reasonable to set it as so. There might be cases that look like they are hopeless. Characters shouldn't just know everything. Secrets exist in this world. Sometimes, we can let user find the solution for it, like an open-ended question instead of a choice.
