Before them stood a gigantic wall nearly a hundred zhang high, enclosing the area ahead in a semicircle and stretching beyond the limits of sight. Flags fluttered atop it. The entire wall was built from enormous ten-thousand-jin boulders, with huge openings spaced along its length. Glossy black barrels protruded from them, apparently belonging to spirit cannons. More importantly, numerous cultivators patrolled back and forth atop the wall, which glowed faintly black. Clearly, its restrictions had already been activated.
Above the wall, they could faintly make out a tall tower piercing the clouds dozens of li away. Li Xiaoya naturally recognized it as the Heavenly Earth Tower, the headquarters of the Heavenly Earth Demon Sect!
Li Xiaoya and the others had already investigated thoroughly. This wall appeared to be the Heavenly Earth Demon Sect's second defensive line. Precisely because this enormous wall stood behind it, security at the first defensive line, the Heaven-Flipping Waterfall, had been so lax. This second line was much harder to cross, but with Dong Santong, that heaven-defying fellow who could ignore restrictions, they naturally thought little of it.

That would run counter to their original plan.
At present, Li Xiaoya and his four companions were invisible, hiding behind a huge boulder!
"Hey, senior brother! We can't
