Cadia's anti-psychic power was exceedingly strong.
This was Cadia's own Blackstone defense activated and amplified to its limit.
These Blackstone Pylons could indeed stabilize realspace while suppressing psychic power, reducing the power of Chaos to the bare minimum.
Elsewhere, Blackstone Pylons of such enormous scale could indeed serve an immense purpose!!!
But Cadia now stood at the Eye of Terror, the domain of Chaos.
It was practically right before the Eye of Terror itself.
This power suppressed the Eye of Terror by drawing upon the power of realspace to jointly restrain the Warp. Under ordinary circumstances, it could have been quite effective, but now the four Chaos Gods were wielding Warp psychic power and ravaging the Warp storms.
The forces of both sides had been locked in confrontation.
It was like two sides standing on solid ground and playing tug-of-war.
The pull between reality and the Warp maintained this fragile balance.
But once some stimulus was introduced between them, such as cutting the rope apart—
Both sides would instantly fall, and the rope would be torn apart as well.
Reflected in realspace, it would mean the entire galaxy being ripped apart.
Cadia's situation was actually extremely awkward now.
To hold Cadia, they needed the Blackstone Pylons to suppress the invading forces of Chaos.
But using the Blackstone Pylons meant bearing the risk of the universe being torn apart.
If they shut down the Blackstone Pylons, the enemy would occupy Cadia. But if they did not shut them down, they would still have to bear this terrifying risk.
Thus, faced with this dilemma where neither advancing nor retreating was possible,
Even The Emperor had to admit that although his power had surpassed that of the four Gods, he had always lagged behind Tzeentch in strategy.
Tzeentch's authority was wisdom and destiny.
