Captives

Everything in the Radiant Fort's puppet base was automatized, but that place was the best masterpiece of a Heaven Rank powerhouse. The power needed to run the base was stolen from the Abyss via the Radiant Fort's array.

The Grey Beastmen's fort didn't have anything that outstanding. There wouldn't be enough power in the long term if they used mana crystals, so they could only use hydraulic power or some other type of mechanical power. But hydraulic power would need very heavy water consumption.

The fort was now sealed, so how could they still dare to use water without restraint?

After surrounding the Grey Beastmen's fort, Lin Yun discovered that their fort was built on top of a huge piece of granite. That way, they wouldn't be attacked from underground, and with the anti-air towers and the city walls, they simply didn't need to worry about defense.

But that also made them lose their access to groundwater. How could they continue to use water like that?
