As for Kasin City, Karina is indeed quite familiar with it. She was the one who discovered this city and found the Moving Fortress here, so there's no need for a lengthy introduction about the city.
So, when Rocky asked her about it, Karina stood up as well and stood beside him in front of the sand table.
"It's too big, bigger than Mist Mountain City."
Looking at Kasin City on the sand table, Karina recalled her previous trip to Kasin City and then pointed out a key issue: the city is too big.
What she said was the truth and, more importantly, the main point.
Although Kasin City is located in a remote area, it is a major city of the Wanzhong Kingdom, with an area twice as large as Mist Mountain City, which will be key to whether Rocky can control Kasin City.
As the battles from this counterattack war show, capturing a city is not particularly difficult. The real challenge lies in how to defend a city once you have taken it, and that is the true hurdle.
