The Old Tree Demon expended a little effort to break through the repulsive force of Black Mountain and entered the cave, while Song Changming followed behind, appearing more relaxed and calm.
With the strength of his physical body, the repulsive force would have even less effect on him.
The roots beneath his feet appeared incredibly hard, so there was no need to worry about their stability, and this tunnel pierced through the mountain by the roots must be over ten kilometers long!
The interior was deep and dark, with only some light sources at the rear, and occasionally stones would fall from above.
Moreover, the further inside they went, the more the energy of the repulsive force accumulated, making it increasingly difficult to bear.
"It seems not everyone can come in..." Song Changming felt the repulsive force against him and thought to himself.
Even the Old Tree Demon in the front was gradually slowing down.
