"Send in the drones and high-rank robots," Zheng Jinren ordered immediately.
"Pangu Unmanned Mecha formation, escort the Manned Antimatter Mecha inside."
"Confirm the Demon God's condition first. Don't expose the manned crews prematurely."

"Tell them not to bring antimatter bombs."
"If Baroque can still move, any bomb-carrying unit approaching will alert it and make it flee again."
"Have the Kona Legion lead the way first and confirm where it is."
Once communications were established, the Kona Civilization quickly responded.
Both sides' drones and robots changed direction simultaneously, descending through the widest underground entrance.
After reaching the bottom, the Pangu Mecha retracted their propulsion systems, while searchlight equipment on their tops and sides continually scanned the rock formations and surroundings.

Ranged units that spat fireballs, hurled projectiles, and so on attacked continuously from behind.
Great Xia's Unmanned Combat Units immediately opened fire. Plasma beams tore through the darkness, and electromagnetic rounds blasted rows of Demon Creatures to pieces at close range.
Kona drones swept overhead, their undersides opening to drop dozens of miniature warheads into the demonic horde.

The Unmanned Legion seized the opening and advanced.
The Demon Clan did not scatter to evade them as they had in the surface battle. They kept plugging the breach with sheer numbers.
