BOOM!
A sudden, deafening boom echoed from several kilometers away, making the ground tremble gently.
The soldiers in the fortress camp looked up, turning their gaze toward the north of the canyon passage. Billowing clouds of dust surged into the sky, kicking up a sandstorm that blotted out the sun. The earth shuddered continuously like an earthquake, causing the camp's wire fences and steel plates to rattle.
"What's going on?"
"An earthquake?"
"It doesn't look like it. It seems like the ground over there collapsed..."
Discussions rippled through the camp. Up in the watchtowers, the sentries raised their binoculars to investigate, their expressions grave.
WHOOSH! WHOOSH! WHOOSH!
Drones streaked quietly through the air, heading straight toward the source of the tremors.
Superpower Commanders like Yue Zhenhong appeared one after another. With solemn expressions, they gathered around Lu Chao.
"Inspector?"
"Let's go take a look."
Several kilometers away.
BOOM!!
