Shi Yan followed Yang Lao, as the two headed for a valley between the two holy mountains.
When there were still some miles away, Shi Yan faintly felt a wave of ferocious and evil consciousness from the valley.
Above the valley, an extremely strong demon energy and Underworld dark energy came through unusual thick indigo and black clouds. The two totally different flavors singularly gathered together and both seemed to be coming from a monster.
"Howl!"
As if it felt someone was approaching, a loud roar that can shake heaven and earth was heard from the valley all of a sudden.
Just as the roar came out, varieties of captive demon beasts in the nearby valley prostrated on the ground in succession, they looked quite scared and didn't dare to straighten up.
