The Tyranids' chain of command actually relied on psychic power.
Where the army attacked and what bugs were hatched behind the lines—all of it was dictated by the hive mind.
Those orders were transmitted through psychic power to synapse creatures of various ranks. These creatures were essentially signal towers of different sizes.
The Brain Bug Tyrant was a large signal tower, Zoanthropes were medium-sized towers, and Tyranid Warriors were small ones.
If they could find a way to kill the Brain Bug Tyrant, the psychic shock wave unleashed by its death would blow apart every Zoanthrope and Tyranid Warrior on the planet.
The Tyranids across the entire planet would go from a tightly organized army to feral bugs fighting on their own!
The Psychic Reversal Bruce Crocodile had mentioned meant finding a way to disrupt the Brain Bug Tyrant while it was casting, preferably just as it unleashed a major attack.
It was like someone working out, doing a clean and jerk with a 300-kilogram barbell.
Just as the guy jerked the barbell overhead, every muscle in his body tensed, you suddenly came up behind him and jabbed him right in the ass!
Even if he were the Hulk, he would lose his strength in an instant, and the barbell overhead would come crashing down and kill him.
Moreover, the Tyranids were all connected through psychic power. This would not only kill the Brain Bug Tyrant, but also blow apart the other Zoanthropes and every Tyranid Warrior on the planet!
Then the Tyranids would truly be finished, unable to pose any further threat. The billion-plus Astra Militarum troops on the planet could march north and wipe them all out!
Li Qinwu was sorely tempted, but just then, the Brain Bug Tyrant finished charging another attack and unleashed a Psychic Blast
