When North Corona and the Great Ruler were approaching, Ange had already detected them. In the pitch-black Void, Ange primarily relied on the Ring of Balance to weigh all things, so as long as they caused disturbances to the surrounding environment, Ange could measure their presence.
Upon hearing that both the Great Ruler and North Corona had arrived, Anthony immediately showed a "just as expected" expression: "He wouldn't dare come here without bringing reinforcements. Lord Nage, according to the plan, it's your move now."
Daring to brazenly sell grain, Anthony, of course, had long prepared a response plan. North Corona showing up alone, compared to bringing along a heap of allies, required a distinct strategy. Now, given the current situation, it's enough to let Negris handle it.
Negris wasn't adept at acting, but Anthony assured him, "No need for 'acting,' just behave as you usually would."
