To be honest, I didn't know when it started... perhaps it was since Yila arrived. The Demon King Territory started to become lazy, or to put it nicely, the intelligence of the leaders started to drop.
The leaders gradually began to give up on their own initiative and willingly waited for Yila's instructions. Just like Vera, who had already given up, said – just listen to Yila.
However, the main reason Vera said this was to avoid listening to Yila's nagging.
After all, once Yila started explaining his actions, he would offer highly detailed plans and countless contingency plans, along with some strange terms and explanations.
Things like "in the short term XXXXX" or "from a long-term perspective XXXXX" were understandable, even "optimal solution," "secondary solution," and "compromise" were barely understandable.
