I think the devils and demons are satiated with just the dark elements so i think they didn't bring food with them. And bruh that's satan not some puny four nation alliance that could be easily sneaked lmao

After we reach this chapter, I realized one of the effects Satan went to destroy all the cities in Barren Land before they go to Rising Sun City: the Rising Sun City would be tightly isolated. Actually, if the devils really didn't know about the map of Barren Land, underground cities, and its underground passages... If SYX has at least one more free city, she can send some group of people through the passage and look for supplies for more war resources from that city. It's never mentioned before that the devil has touched the other four main cities of Barren Land. But, meh. 🤷‍♀️ I hold no much hope someone would use this information to their advantage. Regardless the devils attacked those cities, those cities might have been destroyed before all of the manpower to guard it were transferred to Rising Sun City.

Thank you for the hard work i mean..😅
