Outside the wall tower 23, Sam.
The initial surprise and caution were gone. Now both sides were fully engaged. Only powerful physical and aura attacks were effective against the barrier; their enemies had figured that out.
Spells did not work. But portals would.
Sam had maximum firepower of the wall focused on the individual in the red robe, the portal priest. But the man just moved left and right outside the barrier, punching it till lasers focused back on him. Odd, he could just use the portal to cross. Sam had no idea why that was, but the priest could not enter the barrier using his spell for some reason.
It was a small relief. If even a tiny amount of the barrier broke, the priest could enter and then open a portal for the rest of his army. That man was the priority. An enormous red dragon was headbutting the barrier from above as well. The emperor did not sit still for even a moment. When his fire breath ended, he changed to brute force.
