After they entered the hilly area, countless black shadows emerged from the hills in all directions and rushed towards them. Their numbers were endless, and each and every one of them was extremely crazy.
No wonder LAN Feng and the others suffered heavy losses the last time they came in. If they didn't make preparations, they really wouldn't be able to take it.
However, things were different now.
When the black shadows collided with the flames, they melted like ice and snow, turning into black smoke and dissipating.
Their speed was extremely fast as they kept charging forward. After an hour, they finally made it past the hilly area.
After charging through the hilly area, the surrounding black shadows disappeared without a trace.
As for them, they did not suffer any losses at all.
