"Do it," Allen commanded through the mental link.
"Understood~" In the underground tunnel, Black Sperm's countless small heads simultaneously revealed sinister smiles.
Deep underground, Black Sperm's myriad split bodies surged like a tide, gathering into dense black streams that silently infiltrated the underground structure of the Hero Association Headquarters' command center, following intricate pipes and crevices.
"Hehehe~ Let's give them a surprise from below~"
"Tear down the foundation and make those guys fall~"
"Lord Allen's command is truly interesting~"
The front of the black streams could already see the thick concrete foundation and alloy reinforcement layers ahead, as well as the dense energy sensors and vibration monitors embedded within.
Just as a few small Black Sperm at the very front extended their tiny tentacles, preparing to silently dissolve the first layer of sensors...
Buzz—!
A piercing high-frequency alarm suddenly blared throughout the entire underground network!
Almost simultaneously, the rock layers and pipe walls ahead of all advance routes lit up with dazzling blue-white patterns, instantly forming dense energy grids that blocked their path!
The high-temperature energy field instantly vaporized dozens of the small Black Sperm individuals at the very front!
"Oh no! An ambush!" Countless small heads exclaimed in unison.
Black Sperm's main body suddenly paused, and its countless split bodies rapidly retracted.
"What is this? Did the Hero Association anticipate we would attack from underground?"
Ahead, more layers of energy barriers lit up, completely sealing all paths leading to the underground of the command center.
At the same time, the rock walls on both sides suddenly opened, revealing dozens of muzzles, and high-energy lasers rained down on the gathered Black Sperm split bodies!
Chirp, chirp, chirp—!
As the lasers swept across, large swathes of black individuals were evaporated.
"So troublesome!" Black Sperm complained, its split bodies rapidly dispersing, attempting to find weaknesses in the barriers or bypass the routes, but Drive Knight's defense system was clearly meticulously designed, with virtually no blind spots.
On the surface battlefield, Drive Knight's electronic eye flickered: "Underground infiltration unit has been successfully intercepted; they are temporarily unable to breach the defense network."
Inside the command center, Sitch's spirits lifted upon hearing this: "Excellent! Continue to suppress them! They cannot be allowed to break through from underground!"
However, before he could even let out a sigh of relief, the battle situation on the main screen suddenly changed dramatically!
Gouketsu, who had been on the defensive, suddenly let out a deafening roar. His four eyes instantly became bloodshot, and the injuries on his body healed at a visible speed. A far more violent and ferocious aura than before erupted from him!
"Ten minutes are up! Lord Allen has given permission!" He roared, no longer caring about defense, and his fists, like a madman, slammed towards Bang and Superalloy Darkshine!
Bang's eyes narrowed, and Water Stream Rock Smashing Fist was pushed to its limit, attempting to defuse this sudden, frenzied assault as he had before.
But this time, Gouketsu's strength and speed had clearly increased by a notch. His punch tore through the air, and the resulting shockwave directly shattered the surrounding ground!
Bang!
Although Bang barely managed to deflect the frontal impact, the violent aftershocks churned his blood, forcing him to slide back over ten meters before stabilizing himself!
Superalloy Darkshine let out a low growl, his muscles bulging, his bronze skin gleaming with a metallic sheen, and chose to meet the attack head-on!
Boom—!
Their fists collided like meteorites striking the earth, and a terrifying shockwave exploded in a ring!
Superalloy Darkshine grunted, actually staggering backward from Gouketsu's desperate blow, each step leaving deep imprints in the ground!
"What?!" Atomic Samurai was startled, and with a flick of his blade, he was about to strike Gouketsu's wide-open flank.
But Gouketsu didn't dodge or evade at all. His other arm swept across like a steel whip, forcing Atomic Samurai to retract his sword and leap back.
Flash advanced like a ghost, his kunai stabbing directly at Gouketsu's old injury on his back.
Gouketsu suddenly twisted his body, ramming his shoulder directly into Flash!
Crack!
A sound of bone cracking rang out; it was Gouketsu's shoulder being pierced by Flash's kunai, but he paid no mind. The impact sent Flash flying!
"This guy's crazy!" Atomic Samurai spat.
Gouketsu's four eyes were blood red, breathing heavily, his wounds healing visibly. He no longer paid attention to Bang and the other three, and suddenly looked up at Tornado, who was restraining Centipede Elder in the air.
"Centipede Elder! Go!"
Centipede Elder, who had been firmly suppressed by Tornado's Telekinesis and appeared to be on his last legs, suddenly emitted a muffled roar from within his massive body. All his wounds simultaneously erupted with large amounts of green venom and steam!
A hint of ferocity flashed in his countless compound eyes, and his enormous body suddenly inflated by a full circle as if being pumped up!
"Oh no! It's going to self-destruct its core energy!" Child Emperor's terrified voice rang out in the communicator, "Tornado! Let go of it quickly!"
Tornado's green eyes narrowed, and almost instinctively, she instantly withdrew most of her Telekinesis restraints, leaving only a thin barrier to protect herself and the heroes below.
Rumble—!!!
Centipede Elder's massive body did not explode; instead, it transformed this terrifying energy into an unprecedented violent jet. With this recoil, its massive body plunged into the ground like a drill!
At the same time, all the gaps in its carapace once again sprayed a rain of high-pressure venom far exceeding what came before, covering a vast area and instantly forcing all the heroes to retreat or defend!
The earth trembled violently, and a huge pit was drilled out. Centipede Elder's figure rapidly disappeared underground.
At the same time, Gouketsu stomped the ground, and his massive body also sank downwards. Hellfire Flame and Gale Wind immediately led the remaining Monster army, charging forward desperately to cover their leader's retreat.
"Don't even think about running!" Tornado shrieked, angered by their trick. Her green Telekinesis erupted again, transforming into a giant hand that grabbed towards the spot where Gouketsu had sunk underground, but she grabbed nothing, only large amounts of dirt and rocks.
"Chase!" Atomic Samurai said without hesitation, about to rush into the Hole.
"Wait!" Bang stopped him, his old face grim, "The underground situation is unknown, there might be more ambushes. Don't pursue cornered foes."
Superalloy Darkshine looked at his slightly numb arm and said in a deep voice, "His last attack, his strength increased a lot."
Flash silently landed back on the ground, his arm bent somewhat unnaturally, clearly having sustained some injury from the collision.
On the battlefield, the remaining Monster army, led by the executives, scattered in all directions like a tide. The heroes subconsciously wanted to pursue, but Bang stopped them.
"Clear the battlefield, prioritize treating the wounded, and consolidate the defenses! Be careful of enemy feigned retreats and ambushes!"
Inside the command center, Sitch watched Gouketsu and Centipede Elder successfully escape, and slammed his fist on the control panel: "Damn it! They still got away!"
But he quickly calmed down, "Drive Knight, track their underground signal! Tornado, Metal Bat, immediately clear the remaining Monster on the battlefield! Everyone else, remain vigilant to prevent a second wave of attacks!"
On the left flank, Muzan quietly watched the Monster army collapse and retreat, a glimmer of light, hard to detect, flashing in his crimson eyes.
"The Ancestor's plan has entered the next phase," he murmured to himself.
Akaza's heart itched as he watched the fierce battle, and he couldn't help but ask, "Lord Muzan, can we…"
"Continue to wait," Muzan said indifferently.
At the top of the cooling tower, Allen watched Gouketsu and Centipede Elder successfully retreat as ordered, and Black Sperm was temporarily intercepted. His face showed no expression.
His perception still enveloped the entire battlefield, savoring every trace of energy fluctuation in the air.
Just as the Monster army completely scattered and the heroes slightly relaxed their guard, that very instant...
An extremely faint, yet unusually deep and ancient fluctuation, like a stone dropped into a calm lake, quietly rippled out from a certain spatial point on the edge of the battlefield.
It's here!
