Three thousand years was a long time for mortal lives.
But for higher-dimensional powers like the Destruction Divine Kingdom and the Mechanical Civilization, it was merely a normal preparation cycle before a major expedition.
The war factories of Gear Time-Space had scarcely ever stopped.
Batch after batch of destruction-adapted Mechanical Legions emerged from the Super Intelligent Factories of the Northern Star Ring Zone.
Their outer armor was no longer a single metallic color, but covered in a layer of dark gray Final Silence coating.
This coating came from Final Silence Ash Crystals, Cube Time-Space sealing runes, and the Mechanical Civilization's independently developed active deposition technology.
It could not completely withstand the Destruction Crystal Tide.
But it could slow the rate at which the Mechanical Cores were eroded.
In an extreme environment like Destruction Time-Space, lasting one more hourglass's worth of time could mean transmitting back one more valuable set of data.
Beyond the ordinary Mechanical Legions, the Mechanical Civilization had also specifically built thirty-six entrance-zone War Fortresses.
These War Fortresses did not pursue high-speed movement.
They were like enormous metal wedges.
Once deployed into the entrance zone beyond the Bronze Gate, they would immediately unfold layers of Rule Anchor Points, nailing down the surrounding space.
Inside every War Fortress were preinstalled Final Silence Ash Seal arrays, Destruction Crystal Tide isolation chambers, battlefield recovery passages, and small Skynet Nodes.
Saine's positioning for them was very clear.
Not to charge.
But to take root.
As long as three War Fortresses could gain a firm foothold in the entrance zone, the Mechanical Civilization would gain a stable observation point.
As long as ten could hold their ground, the Bronze Gate entrance zone could form a preliminary war base.
Saine knew perfectly well that the mortality rate of the first low- and mid-tier legions
