Xu Luo glanced at Sui Yan and said, "Alright, go ahead and activate the defense."
Sui Yan said, "It's already active!"
"Huh?" Xu Luo was genuinely stunned this time. He stared blankly at his courtyard walls, which hadn't changed at all. Then, he released his Divine Sense, intending to sweep it over the area, but it was blocked right above the walls!
All Xu Luo could perceive was a chaotic void. This astonished him. "This Black Tortoise Array… it can even block Divine Sense?"
Sui Yan laughed. "It seems you don't even know what a miraculous book that Mechanical Skill tome you gave me was, Third Brother... That's right. As long as the array is active, not even a fly can get in! Even a mighty expert at the Sword Saint Realm wouldn't be able to penetrate it with their Divine Sense!"
"Hiss!" Xu Luo couldn't help but suck in a sharp breath. He felt utterly shocked. Only now did he finally understand just how precious this great gift from Sui Yan truly was.
