Inside the Fortune's Biological Laboratory, Father Anthony addressed the hundreds of biological researchers under his command:
"Based on the samples recovered by the collection teams, we can now confirm that the Tyranids have developed antibodies against Bioweapon No. 1. It's time to deploy Bioweapon No. 2.
Bioweapon No. 2 primarily attacks the Tyranids' respiratory systems. Once it's deployed, the collection teams are to depart immediately and retrieve infected samples for us to study."
The sample solution for Bioweapon No. 2 was injected into culture dishes by the staff for replication.
Once replicated, the solution was loaded into specially designed Macro Cannon shells and fired toward the surface, where they exploded in the atmosphere.
This time, it took about eighteen hours for the plague to break out among the Tyranids.
On the battlefield, amid the roar of artillery, Blade Bugs and Gun Bugs coughed incessantly, thick white foam seeping from their mouths and nostrils.
Large Tyranid war beasts-the tanklike Hive Tyrants and the Spore Cannon Bugs that resembled self-propelled artillery-vomited mouthful after mouthful of purple blood.
Across the entire planet, every component of the Tyranids' offensive system was weakened as their lungs became infected, congested, and clogged with mucus.
One day after Bioweapon No. 2 was deployed, Father Anthony received the biological samples he wanted: a dozen or so Blade Bugs and Gun Bugs.
A dozen Fleet Iron Guard members chained these Blade Bugs and Gun Bugs together, their limbs broken, and delivered them to Father Anthony's laboratory.
Father Anthony personally took his place at the dissection table and removed the swollen, congested lungs from the Blade Bugs and Gun Bugs.
His assistant stared at the ravaged lungs and exclaimed:
"My lord, your weapon worked! With their lungs rotted this badly, they've essentially lost the ability to breathe!"
