As three aerospace fighters flew over the mountain peaks, a sturdy barrier came into view amid the interweaving of black-and-red earth and verdant hills. It stood thirty to forty meters high, was built entirely from M3 Alloy, and stretched for over a hundred kilometers, coldly marking the border between the two regions.
Above the barrier, countless light and heavy cannons had been arranged in orderly arrays of overlapping firepower at every corner.
The light from countless formation patterns and talismans gathered, like electronic imprints carved into the barrier's surface, as the core spirit-energy amplification device continuously powered them.
Two intersecting formation energy barriers took shape over the base, their spirit-energy fluctuations and particle rhythms joining together as tightly as lacquer and glue.
Though the Mountain Spirit Eternal Array was originally only a Second-Tier upper-grade formation, with the support and enhancements of technological devices, it had reached the power of a Third-Tier lower grade or even middle grade.
Beneath the grand formation, a base like a fortress nestled in a mountain ravine appeared before Bai Yi's eyes.
The entire base covered nearly one hundred square kilometers. Aside from the monitoring tower at its very center, clusters of buildings with many different functions stood all around it.
A logistics support center, a warship repair and maintenance center, a resource extraction and recycling center, a virtual combat simulation center...
The buildings, rising and falling across the landscape, formed a complete forward combat base.
Along the transit rails, countless base personnel rode hovercars and hoverboards between buildings.
Deep in the mountain range behind the base, over ten thousand labor and engineering robots were mining a First-Tier resource deposit. They loaded the ore onto trucks and continuously delivered it to the Cangshan Small Realm's main operations base, as well as
