The Pangu Unit's scanning system activated, and various detection beams swept in sequence over the crater's rim, shattered rocks, and nearby underground collapse zones.
[No intact biological tissue detected on the surface.] [Residual high temperatures detected. Intensity continues to decline.] [No signs of target activity detected.] [No signs of target escape detected.]
Inside the Command Center, everyone stared tensely at the streams of data.
They all knew there was nothing unusual about finding no remains on the surface.
Antimatter would completely annihilate any matter within its contact range, but there was not much antimatter. Its greatest power lay in the enormous energy released when matter and antimatter annihilated each other.
Under that explosion of energy, Aker could hardly have left an identifiable corpse.
Besides, the truly critical area was underground.
"Seismic source nodes deployed!"
The report came over the radio.
Several Attack Helicopters swept past the perimeter at low altitude, dropping sixteen Seismic Source Sensor Nodes around ground zero.
After landing, the nodes quickly deployed anchoring claws and drilled into the shallow rock and soil. They established short-range communications with one another, gradually forming an underground listening network covering the Northwest Defense Zone.
"No new digging signals underground for now."
"Keep listening. Don't stop." Zheng Jinren tapped a finger on the desk.
"Send the Burrowing Robots down."
Four Earth Dragon Type One Burrowing Robots detached from the underside of a Transport Plane and landed at the crater's edge.
The drilling wheels on their heads spun at high speed as they bored down through the strata loosened by the explosion.
Avoiding areas where temperatures were too high, they used internal navigation to search for the old passages previously excavated by the nine Burrowing Earth Dragons.
"Robot One has reached three hundred meters underground."
"Two has reached four hundred meters."
