Iax had anticipated the Tyranids' counterattack.
When the fleet arrived and began smelting the fragments of Leviathan's tendrils, the Shipyard beneath the Industrial Ship had already sprung into action. Countless materials were fused together, and a gigantic bomb six kilometers long was under construction.
Its original target had been Leviathan's main body, whose size remained unknown, rather than its tendrils.
But the incoming, interwoven tendrils of Leviathan still fell within Iax's computational limits.
After modifying the Imperium's Cyclonic Torpedoes earlier, Iax had gained some understanding of the weapon.
The weapon being built beneath the Industrial Ship was a massively enlarged version of a Cyclonic Torpedo.
This torpedo likewise employed a plasma-locking structure from the Old Era, and was charged using the Pectaro's Antimatter Energy supply.
Compared with an Atmospheric Incineration Cyclonic Torpedo of the same volume, it was nearly six times as powerful.
And this gigantic bomb was almost thirty times the volume of an Imperial Cyclonic Torpedo.
Its energy content was more than a hundred times that of a standard Imperial Cyclonic Torpedo.
Iax had calculated that its detonation would shatter at least half a star system.
Its effective range could reach ten light-seconds.
Though the actual effects remained unknown, that did not prevent Iax from making a cautious assessment of the damage it could inflict.
Iax watched the three rapidly approaching tendrils.
The retaining mechanisms beneath the Industrial Ship slowly released. After putting several hundred kilometers between itself and the bomb concealed among the Flesh Fragments, the fleet activated its Warp Engines.
The veil of the Warp slowly opened, and the fleet filed through.
The Great Devourer's shadow roared through the Warp, stirring up violent waves.
Immense energy pressed against the Gellar Fields of every ship.
Having never encountered such extreme energy tides in the Warp before, Iax
