While Xiao Qi and Mu Xue, relying on the Green Lotus Sword Domain, forcefully slew the second Demon Marshal and continued advancing toward the Demon Nest's deepest depths, in the rear's massive blood pool chamber, the battle had entered a white-hot grinding stage.
Third Senior Sister Liu Yun and Zhao Tiezhu stood like two reefs in a sea of demonic creatures, enduring unimaginable pressure.
Her sword light was no longer as sharp and unparalleled as at the beginning, but had gained more ruthlessness and resolve. Liu Yun's hair was slightly disheveled, her moon-white daoist robe stained with dots of demonic blood and corrosion marks. Her breathing was slightly rapid, but her sword remained steady. Each swing precisely took several demons' lives ordisrupted a lethal attack. Her sword heart, honed through such high-intensity combat, had become even purer. Her sword intent grew more concentrated, showing faint signs of breakthrough.
Zhao Tiezhu had completely become a blood man—most of it from demons, some his own. His dark-golden luster had faded considerably, covered with deep and shallow claw marks and scorched burn marks. But he remained like an tireless war beast, roaring, swinging his fist comparable to divine weapons, shattering and crushing demons that pounced on him one after another. Beneath his feet, demon corpses had nearly formed a small mountain. Elite hunters' bone blades left deep wounds reaching his bones, yet he seemed incapable of feeling pain, becoming even more berserk, pinning those strongest demonsfirmly so they had no chance to interfere.
Their surroundings were an inexhaustible sea of demonic creatures. Shadow demons, space-splitting insects, various grotesque fusion monsters, and resentful soul demons continuously crawling from the blood pool... They surged like tides, fearless of death. Throughout the chamber, demonic shrieks, weapon clashes, energy collision rumbles, and the sounds of flesh being torn mixed together, composing a brutal symphony of death.
The reason these two could persist until now, besides their solid strength and tacit coordination, was that they were not fighting alone.
At the battle's edge, in ignored shadow corners and deep within flesh wall folds, unremarkable metal spheres would occasionally roll out silently, embedding into flesh walls or mixing into demon corpses. These spheres' surfaces were inscribed with extremely fine runes,emitting no energy fluctuations, perfectly blending into the environment.
This was Second Senior Brother's masterpiece—the "Covert Energy Node Disruptor."
These disruptors' function was not direct killing, but continuously releasing a specific frequency of weak spiritual waves. For individual demons the influence was minimal, but they could extremely covertly interfere with the Demon Nest's internal energy network stability. Especially for low and mid-level demons relying on the Demon Nest's unified energy supply, they caused subtle sluggishness in movement and brief energy circulation interruptions.
It was this seemingly insignificant interference that made the demon tide's assault not flawless. At crucial moments, there would always be a trace of uncoordinatedness, giving Third Senior Sister and Zhao Tiezhu precious moments to breathe and counterattack. Otherwise, facing such endless siege, even if the two were powerful, they would have been worn down long ago.
And now, Second Senior Brother's "Iron Coffin" was acting like the most top-tier assassin, silently infiltrating to a hidden layer beneath the blood pool chamber, heavily protected by thick biological tissue and complex demonic pattern arrays.
Here was one of the Demon Nest's secondary energy core nodes!
A massive, like a heart pulsating dark-red tumor occupied most of this layer's space. The tumor's surface was covered with thick energy conduits like blood vessels, connecting up, down, left, and right, continuously transporting pure demonic energy throughout the Demon Nest. Within the tumor was a terrifying,tremendous energy that even disturbed the surrounding space.
The "Iron Coffin" floated before the pulsating tumor, runes on its surface flickering in some complex pattern, performing final scans and calculations.
"Structure analysis complete... Energy flow model established... Core's weakest point confirmed... It's here!" Second Senior Brother's divine sense carried extreme focus and a trace of suppressed excitement.
On the metallic rhomboid's side, a slot silently slid open, extending a mechanically precise arm flickering with cold light. At the arm's tip, not a weapon, but a fist-sized, entirely black, smooth as a mirror polyhedron crystal—the Chaos Annihilation Bomb!
This bomb condensed Second Senior Brother's lifetime of learning and the Alliance's highest technological achievement. Its core principle was not simple explosion, but triggering small-scale chaotic forces, causing complete energy lawchaos and collapse, producing chain reactions, ultimately forming a local "law vacuum" that annihilated all ordered structures within range!
The mechanical arm stably and precisely placed the Chaos Annihilation Bomb at a key node of the pulsating tumor's energy flow, also the relatively weakest "seven-inch" point of defense.
The moment the bomb embedded, its smooth surface immediately simulated surrounding tumor tissue's energy fluctuations and morphology, perfectly concealed.
"Implantation complete! Detonation sequence set—triggered synchronously with specific spatial wave resonance from external Zhou Tian Xing Chen Great Array main cannon strike!" Second Senior Brother swiftly completed the final settings.
This meant that only when the external Zhou Tian Xing Chen Array launched an attack powerful enough to shake the Demon Nest's body would this hidden "poison stinger" within the Demon Nest be activated, delivering a fatal blow from the inside!
Having done all this, the "Iron Coffin" lingered not a moment, immediately returning along the original path. It must reunite with Third Senior Sister and Zhao Tiezhu as soon as possible, preparing to evacuate before the bomb detonated, or... face the final result.
When Second Senior Brother's "Iron Coffin" reappeared at the blood pool chamber battlefield's edge, he immediately transmitted information through divine sense to the two still engaged in bitter battle:
"Task complete! Prepare to shift to designatedevacuation point three! Repeat, task complete!"
Liu Yun and Zhao Tiezhu,gritting their teeth while holding on, upon hearing this news, spirit immediately lifted!
"Well done, Second Senior Brother!" Zhao Tiezhu roared, smashing an elite hunter before him flying with a punch, seizing the chance to catch his breath.
Liu Yun's sword light converged, her gaze scanning the battlefield sharply, searching for an opportunity to break through.
"GO!"
The three no longer engaged resolutely, fighting while retreating, beginning the arduous movement toward thethe previously planned evacuation point threeevacuation point direction, relatively far from the core region. They had attracted attention long enough, created precious opportunities for Second Senior Brother, and most critically, the "Chaos Annihilation Bomb" buried deep within the Demon Nest's energy node was already in position, waiting only for the deciding external strike!
Internal sabotage was complete. Now, everyone's hope rested on the external Zhou Tian Xing Chen Array gathering the power of 365 Nascent Soul cultivators, and the Void Piercing Shuttle carrying final hope. The final piece of the inside-out coordination puzzle had fallen.
