The difficulty of the Spatial Seal Barrier increases with the teaching difficulty, but Xu Huo had already completed the content of Lesson Three, so he quickly dug a hole in the Space Barrier and crawled out, followed by Qiu Xiangming.
"The air outside is so much better." Back in the previous city space, Xu Huo spoke as he prepared to head to the next destination.
Qiu Xiangming walked behind him, a bit surprised, "You still want to try again? Don't you need some rest?"
Controlling Spatial Power for long periods is exhausting, both physically and mentally. You can barely restore stamina with a Potion, but mental energy isn't so easy to fix, especially since you're learning as you go, which makes it even more draining... His mental stamina is that good?
Xu Huo touched his chest. The wound had healed, but his internal organs still ached faintly.
"Have you ever met the dungeon mini boss of the Metal City?" he asked.
"Have you?" Qiu Xiangming retorted.
