Chapter 157: 94. Underground Encounter_2

The dark green pollutants that tainted the river water were sprayed out from the round holes in the riverbed.

Although the pollutants were soon diluted by the flowing river water, the lingering murky green hue still worried people about the future of the river.

"Click-clack click-clack..."

Light footsteps approached from a distance, passing by the jetting chemical emissions at the bottom of the river.

Noland Lee glanced at the greenish hue in the river water and silently lamented, "Polluting the environment is shameful."

He tried to lighten his steps as he moved northward along the underground river, putting aside his distraction and focusing on the task.

He was in the underground space in the southern part of the Legion Fortress, with the vast steam boiler room right above him.

Going from here to the north, he would pass under the steam train station, the fortress main road, and the armor workshop before reaching the area right beneath the Legion Castle.
