Discovered?

In a dark and dense forest area closest to the battlefield, a team of four scout students were carefully moving through the trees, trying to go around the whole battlefield by skirting the edges of the forest ...

They could clearly hear the violent sounds of artillery and explosions not far away, and every once in a while, they could feel the sudden tremors of the ground when a mecha crashed from the skies into the ground. Each time, they would be frozen in terror, afraid that some stray artillery or even mecha would just fall directly on them.

"You guys, still okay?" Qi Long swiped off the sweat on his forehead, and turned back to ask his teammates behind him.
