"A world held captive," Shen Hao already had a general understanding of the world's current state, yet he also felt it confirmed his suspicions.
After all, this world couldn't be simple, otherwise, it wouldn't have been chosen as a Trial World. He had even been prepared to encounter worlds completely overtaken by Weird Demons, but now, remnants of civilization still existed, even if captive, and they were of immense value.
Firstly, it would be the height of foolishness for a Civilization System to rely solely on its own power in a battlefield of this magnitude.
The number of indigenous civilizations would be anything but small. Even if their strength was relatively weak, based on their sheer numbers, they could still play a significant role. If they could even slightly reduce the sacrifice of soldiers from the Human Civilization System, it would be worthwhile.
