A few light years away from the Imperium border, the huge Warp Route mouth was opened.
Heart of the Forge rushed out with hundreds of ships.
Although Iax used Tyranid Swarm's attack direction to make a rough range prediction, the scene in its field of vision was really beyond comprehension.
There is an extremely vast void area outside Galaxy.
There is nothing here, almost no stars exist.
However, Iax saw for the first time what might be the tentacles of those terrifying creatures of Tyranids.
Less than a light-year away, there is a truly giant thing floating in the void.
It was a huge collection of flesh and blood, with a size of more than ten light-years. Such a terrifyingly large volume did not collapse in mass and became Black Hole, which Iax couldn't understand.
The shape of this mass of flesh and blood is somewhat like the virus on Biology, or similar to a two-dimensional flattened sea urchin.
The huge piece of meat was squirming extremely slowly.
The astronomical-scale tentacles we have encountered are the flagella extending from these terrifying 'giant viruses'.
And the volume of some tentacles has approached the aggregation of the remaining flesh and blood.
The direction in which two of the tentacles extend is exactly the direction of Grendl Stars.
Its distance extends for more than ten light years.
The end is several light years thick.
Iax also discovered that these tentacles would extract nutrients from these huge flesh and blood to further extend themselves and move forward.
According to speculation, the nutrients recovered by these tentacles after invading the nearest world may not be transported back, but directly absorbed by the tentacles themselves and extend further forward to absorb more nutrients.
At this time, these so-called tentacles look more like retractable Vines.
A series of discoveries allowed Iax to understand for the first time how these organisms Xenos spread.
These organisms eat up a river system completely, then gather all the biomass together to form a huge piece of meat of indescribable size, and then step into the empty chasm of the river system and float to another place.
Over the long years, these creatures of collective will have maintained their survival through constant self-feeding.
Eventually when they reach the next river system they will split themselves apart and try to invade and engulf more worlds.
However, Iax does not know that this huge piece of meat that is more than ten light years in size is not all.
This is just a small piece of Milky Way's more peripheral Necron Defensive Line that has slipped through the net.
On a battle front with a scale of hundreds, thousands or even tens of thousands of light years, a fragment of Tyranids organic polymer that is more than ten light years away is not enough to attract Necrons's attention.
The reason why Tyranids has not launched a large-scale attack is not only because of Necrons's defense line outside Milky Way.
There is another more important reason.
They move too slowly.
The terrifying size of Tyranids's biological meat piece also means that it requires extremely terrifying energy consumption to push it forward.
When leaving a river system, these organisms will make an initial push in the form of dispersed daughter bodies. This is the force generated by the spin of the river system.
Then they began to cross the river system divide at an extremely slow speed.
There are almost no celestial bodies in the void area between the river systems, which also means that these super Flesh Continent will not be affected by additional gravity and damage their structures.
The Tyranids flesh-and-blood children that were thrown into the void using the spin of the river system began to gradually merge and form these Flesh Continent that were several light years or even dozens of light years away.
Afterwards, these huge pieces of meat will approach, gather, and devour each other until they drift for billions or even tens of billions of years and gradually reach the next river system.
Under normal circumstances, once they reach the next river system, these super Flesh Continents composed of countless daughter bodies will split into various small pieces, and then go further into the river system to start their gluttonous feast.
However, this ancient technology failed in Galaxy.
They encountered Necrons first.
Then he fell directly into the flames of war in the void.
Necrons cannot provide organic matter supplement for Tyranids, which is a losing battle for Great Devourer.
For this reason, he had to try to rush into Galaxy and start replenishing biomass as soon as possible.
The long journey across the river system chasm has made Great Devourer extremely hungry.
Anyone who has been starved for billions or even tens of billions of years will not have a good temper.
Especially when he arrived at the next table only to find a steel durian that couldn't be opened.
But the torture of hunger drove Great Devourer crazy. He grabbed the whole durian fiercely, trying to taste the flesh and blood smell from the cracked gap with the sharp thorns.
If the defense line is too large, even Necrons will be unable to cope with it.
So after all, there are still some Tyranids fish that slipped through the net and successfully passed through Necrons's defense line and entered the edge of Galaxy.
However, even so, there is still some "toxin" in the durian, which makes Great Devourer, who sticks out his tongue like an anteater and wants to lick some pulp, uncomfortable to eat.
And since Men of Iron appeared, Great Devourer discovered a new problem. Although there was a lot of meat in the durian, the core was still metal. What was even more outrageous was that the core began to reverse attack his tongue that was trying to stick into the gap.
Iax The appearance of Mechanicus Fleet is so conspicuous in the void at the edge of Milky Way.
Especially the huge size of Heart of the Forge.
Although compared to Tyranids, which is more than ten light years in size, Flesh Continent can be said to be tiny.
But in the eyes of Great Devourer, this is like the grit in your shoes and the leaves between your teeth.
Although it is small, it is extremely abrupt and interesting.
Soon the huge Flesh Continent began to move. The huge astronomical-sized tentacles began to move from the base, and a branch tentacle with a width of tens of light minutes quickly extended from the light-year-sized tentacle.
The terrifying biological structure swept across countless voids, sweeping towards the tiny fleet of Iax.
Although the main bodies of these biological structures move slowly in the void, it does not mean that the speed of their sub-bodies is equally slow.
The alarm inside Mechanicus Fleet started blasting like crazy.
Warp Route was deployed, and other ships fled into Warp.
And Heart of the Forge launched a full firepower projection aimed at the trajectory of the tentacles approaching at dozens of times the speed of light.
Especially after the two beams of Annihilation Cannon were shot out, Heart of the Forge penetrated into Warp Route without stopping.
Mechanicus Fleet began to change course and returned to Realspace a few light minutes above the vertical coordinate of the original position.
It is not difficult to start moving in a stationary state, but it is different if you want to change the direction of operation later.
Especially given the terrifying acceleration brought about by its huge size.
The newly grown tentacle branches unsurprisingly hit the attack trajectory predicted by Iax.
The dense explosion instantly broke half of this 'slender' tentacle.
A large amount of blood and huge biological debris were scattered in space.
