My Drill Can Pierce the Heavens

This journey, aside from expending some energy, hadn't resulted in much loss. The troops that suffered casualties could mostly be resurrected at the Resurrection Altar, and the resources spent were just a small fraction of what we're about to gain.

Ji Chen revealed a mysterious smile and, as if walking on calm waters, made his way to the hill.

Yasen and the others, although puzzled, followed behind.

Seeing Ji Chen and Yasen enter, they stopped their activities and saluted Yasen.

"Lord Yasen."
