Chapter 58: New features, excavating.

Far away from the battlefield, several hundred kilometers east of Blue Cloud Mist City, another scene was unfolding deep beneath the earth.

Near the eastern border of the Great Yan Kingdom, which faced the Thousand Wind Mountains, a large underground chamber had been excavated several hundred meters beneath the ground.

The place was hidden from the outside world, with only a narrow entrance leading down into the depths.

Inside, Chen Yuan and Chen Feng were busy preparing the place.

The stone floor around them had been carefully cleared, while piles of excavated rocks had been pushed toward the sides of the chamber.

Chen Feng was examining one section of the underground chamber while Chen Yuan worked on another, occasionally moving a pile of stones out of the way or inspecting the walls to make sure everything was suitable.
