Instant array -2
Old Gu looked around for a few seconds to see if anyone understood what Robin was talking about, but silence dominated the hall. Old Gu sighed in disappointment and bowed slightly, "We apologize for not being able to see. Please, Your Excellency, enlighten us."
Robin smiled, still looking at the field hospital, "Tell me, what is the biggest problem with this design?"
Old Gu took a long look towards the field hospital before answering, "In short, he has two big problems. The first is that it takes a large number of people to activate the array, which means it is impractical in high-end battles. The second is that the array will disappear if a single banner moves just a little bit, and as long as the banners are fixed in the ground like a normal banner, this will inevitably happen."
