Chapter 137: Infrasound Directed Impact Bomb Shows Its Power

Three Prison Guard Beast units, like moving steel fortresses, steadily advanced through the river valley.

Behind them lay overturned armored vehicles, smoking tank wrecks, and vast numbers of White Elephant soldiers who had laid down their weapons, dazed and at a loss.

But as Chen Guang said—the battle was not yet completely over.

On the east and west slopes of the river valley, about two companies of White Elephant remnants, under the desperate organization of junior officers, were rebuilding their defensive line using the rocky terrain.

They dismantled their heavy equipment, split into small units, and attempted guerrilla resistance with light weapons and individual rocket launchers.

To buy time for the main force's "orderly withdrawal"—or rather, rout.

"These guys are still pretty tenacious," Li Yang marked several newly appeared fire points on the monitor.

"On the east slope there are at least four light machine guns, and on the west slope three rocket‑team squads are moving."

"Just a cornered beast's struggle," Chen Guang said without looking up, his fingers swiftly sliding across the control panel.

"The Torch Dragon has finished battlefield holographic modeling; all heat signatures and moving targets have been marked."

"Wang Hao, the target data you wanted has been sent over."

"Here it comes!" Wang Hao rubbed his hands, eyes bright as he stared at the console before him.

The screen showed the real‑time feed from the special drone called the Hunting Falcon.

This drone resembles a soaring raptor, with a peculiarly shaped cylindrical launch device mounted under its fuselage.

"This is the first combat use of our new toy," Wang Hao said proudly to the young technician beside him.

"See? The Hunting Falcon Shockwave Bomb—I personally helped design it. It doesn't strike or kill; it cures all kinds of disobedience."

The young technician asked curiously, "Officer Wang, isn't this just… a big shock bomb?"

"Superficial!" Wang Hao snapped, "A shock bomb is some antique—what we have is an infrasound directed impact bomb!"

"The principle is to use a specific frequency of infrasound to induce resonance in human viscera, causing dizziness, nausea, and loss of balance."

"Put simply, it makes you feel like you've ridden a roller coaster for three days and three nights without eating."

As he spoke, he adjusted the launch parameters: "The key is that this thing's effective range is controllable and the damage is reversible."

"After it hits, the enemy lies on the ground vomiting for half an hour; they get up, dust themselves off, and are fine—except they won't be fighting for a while."

"Civilized, get it? We call this civilized warfare—after all, it's still within exercise bounds, we must keep casualties low, otherwise it's straight to total annihilation."

At that moment, the White Elephant soldiers on both slopes of the river valley still didn't know what they were about to undergo.

On the east slope, a lieutenant was frantically pounding the communicator—of course there was no reply, as all electronic communications had been taken over and blocked by the Torch Dragon AI.

He gritted his teeth and shouted at the nearby soldiers, "Forget the comms! Our mission is to hold them off!"

"Wait till the main force pulls back to the valley exit, then we'll disperse and withdraw! Remember, shoot and scoot, don't dig in—"

He couldn't finish his sentence.

Because everyone heard a strange sound.

Not an explosion, not gunfire, but a low‑humming that seemed to rise from deep underground.

The frequency was very low—so low it was almost inaudible—but it could be clearly felt.

It was like someone lightly tapping your breastbone with a heavy hammer.

"What sound?" a soldier nervously looked around.

The next second, an anomaly erupted.

The first to feel something wrong was that lieutenant.

He suddenly felt the world spin, his stomach churn, and everything before his eyes sway.

He tried to grab the nearby rock, but his hand grasped nothing.

It wasn't the rock moving—his sense of balance had gone completely awry.

"Urgh—"

He doubled over involuntarily and vomited violently.

Then came a second, a third…

On the slope, all White Elephant soldiers within a 150‑meter radius of an invisible center almost simultaneously displayed the same symptoms:

violent dizziness, nausea and vomiting, and limb weakness.

Some collapsed outright, some leaned on the rock retching dryly, and others staggered a few steps before falling into the bushes.

Their weapons slipped from their hands, and their exoskeleton helmets were torn off—because vomit blocked their breathing.

Within twenty seconds, the entire east‑slope resistance collapsed, leaving only waves of vomiting and painful groans.

The situation on the west slope was exactly the same.

The difference was that those soldiers saw the source of the "attack."

A slender‑shaped special projectile, its tail still spinning with stabilizing wings, hovered silently eighty meters above the ground.

The midsection of the projectile bore several glowing ring‑like structures, flashing on and off in a regular pattern.

That was the payload of the Hunting Falcon Shockwave Bomb.

It air‑burst at the preset altitude, releasing a directed infrasound shockwave.

"Devil… this is the devil's weapon…" a soldier with a flicker of consciousness muttered, then his head lolled and he passed out.

Inside the Dragon Chant cockpit, Wang Hao stared at the biological‑sign data fed back by the sensors, grinning from ear to ear.

"The effect is better than the lab data!" he reported excitedly.

"Within the effect zone, 93% of targets lose combat capability within a minute, and the remaining 7% suffer severe mobility impairment."

"The key is that there's hardly any damage!"

"Heart rate and blood pressure may swing wildly, but they stay within safe limits and return to normal within half an hour after the effect stops!"

Chen Guang pushed up his glasses: "The attenuation of infrasound in the thin highland air is less than expected, so the effective range has expanded by fifteen percent."

"The data's been logged; we can optimize the charge later."

Feng Yan looked at the soldiers slumped this way and that in the surveillance footage, and said calmly:

"Well done. Commander Lei, the threats on both flanks have been eliminated; we can tighten the encirclement."

"Received." Lei Jindong's voice came through.

"Dragon Chant squads, listen up: follow the plan, advance from east and west, and thoroughly clear the battlefield."

"Remember, prioritize controlling enemy officers and technical personnel."

In the river valley, as Wang Hao's Peregrine Falcon finished clearing the field, the battle finally entered its concluding stage.

Twelve Iron Wolf-Assault Type exoskeletons emerged from concealment—they had previously lain hidden in the battlefield's periphery, performing blockade and picket duties.

Now, these light mechs advanced like a real wolf pack, quickly infiltrating the valley center in tactical formation.

Their movements were light and swift, forming a stark contrast with the Prison Guard's heavy might.

The drivers of the Iron Wolf and Prison Beast were all elite personnel personally trained by the Dragon Chant team, with a deep understanding of the equipment's performance and battlefield situation.

One Iron Wolf suddenly slipped sideways while running, its mechanical feet tracing an arc on the sandy gravel before coming to a precise stop beside an overturned command vehicle.

The non-lethal weapon module on the mech's arm activated, firing a high-frequency sound-wave pulse.

Inside the vehicle, the few officers still trying to resist suddenly clutched their ears in pain, losing all ability to resist.

Another Iron Wolf demonstrated a different use of the newly installed laser module.

Its shoulder-mounted laser emitter shot a low-power blue beam that, on the ground ahead of a group of soldiers trying to flee in the distance, "drew" a scorched mark smoking with greenish fumes.

The electronic speaker blared a warning: "Halt! Crossing this line will be considered hostile action!"

The soldiers were frightened and immediately stopped, raising their hands.

Even more impressive was an Iron Wolf equipped with a new shield module.

While it was clearing a machine-gun emplacement, it came under fire from the last few diehards.

Bullets struck the suddenly deployed miniaturized energy shield, sending up blue ripples.

The mech didn't even pause, charging through the hail of bullets to the enemy's front, where a light swipe of its mechanical arm knocked the stunned soldiers to the ground.

"Do you see it? Do you see it?" Li Yang pointed at the monitor inside the Dragon Chant cockpit, excited beyond belief.

"The miniaturized shield generator! Although its strength doesn't match the Prison Beast's main shield, it's more than enough against light weapons—this is the technical bottleneck we only cracked last month!"

Zhao Kaiyuan rare ly broke into a smile: "Energy density is up forty percent, and the cooling structure has been re‑optimized."

"This combat data is priceless; once we're back we can upgrade this module on every deployed Iron Wolf."

Feng Yan nodded, but his gaze fell on another corner of the battlefield.

There, three Prison Beasts had completed the encirclement of the White Elephant forces' command hub.

The bearded commander and his staff were trapped in a natural shelter formed by several boulders, unable to advance or retreat.

"It's time to end this." Feng Yan said softly.

In the ravine, Number One Prison Beast—the very one that had just used the laser blade—strode forward with heavy steps, arriving twenty meters from the shelter.

It stopped, lowered its head, and looked down at the group of officers huddled behind the rocks.

The mech's arm lifted, a module on its arm armor opened, and projected a holographic image—a high‑precision map of the ravine, with red marks showing the remaining White Elephant units and blue marks indicating the Longguo forces' encirclement.

Then a calm, electronically translated voice sounded:

"You are completely surrounded."

"All retreat routes have been sealed."

"All heavy equipment has been destroyed or disabled."

"Further resistance is pointless."

On the hologram, the red dots representing White Elephant units winked out one after another—signifying that they had been subdued or disarmed by the Iron Wolf squads.

"Lay down your weapons, step out of the shelter, and surrender with hands raised."

"This is your final ultimatum."

The mech finished speaking and waited silently.

Behind the rocks, the bearded commander looked around with a deathly pale face.

. Only seven or eight aides and guards remained beside him, all gazing at him pleadingly.

A young staff officer trembled as he said, "Sir… we… we've lost…"

Another officer, eyes red, shouted, "We can't surrender! This is disgrace! We are—"

"Shut up." The commander cut him off.

He drew a deep breath, straightened his filthy uniform, then slowly rose and stepped out of the rocky shelter.

He lifted his gaze to behold the four‑meter‑tall steel colossus before him.

Sunlight streamed from behind the mech, tracing a dazzling edge on its dragon‑scale armor.

The mech's head sensors flickered with a faint blue light, calmly "watching" him.

The commander's trembling hand unfastened his sidearm holster and gently set his pistol on the ground.

Then he raised both hands.

Following his move, the other officers and soldiers behind the shelter emerged one by one, laid down their arms, and surrendered with hands raised.

The last organized resistance collapsed.

Inside the Dragon Chant cockpit, everyone let out a breath of relief.

"All done." Wang Hao stretched, "From the Prison Beast's landing to now… let's see, twenty‑two minutes. Tsk tsk, three reinforced battalions in twenty‑two minutes."

Chen Guang had already begun collating the data: "Combat data for all the new weapon modules have been gathered."

"The laser weapons system exceeded expectations, the energy shield's stability outperformed lab tests, and the stun grenades' effect matched design specs."

"Once we're back we can write a detailed upgrade plan."

Li Yang, still not satisfied, kept watching the monitor: "I recall the driver of Prison Beast Number Three is supposed to be called 'Ying Eagle,' right?"

This operation was really impressive, especially that jumping slash…… Later I need to find him to exchange combat experience.

Zhao Kaiyuan shut down the energy monitoring system: "All Dragon Heart reactors are running smoothly, with no overheating or power fluctuations."

High-altitude environment adaptability verification passed.

Feng Yan listened to the team's report, a faint smile appearing on his face. He then connected to the comms with Lei Jindong:

"Commander Lei, battlefield cleanup is left to you. Handling of prisoners and equipment will proceed according to plan."

"Don't worry." Lei Jindong's voice carried a rare hint of ease: "We could call this… a good start?"

"I guess so." Feng Yan looked out the side window as the transport ship gradually lowered its altitude, preparing to land: "But this is only the beginning."

He paused, then added: "Have the technical team collect all wreckage of the destroyed Mountain Hunting Dog exoskeletons, especially the energy cores and control modules."

"Eagle Country must have done quite a bit of work on this; it's worth studying."

"Understood."

Comm ended.

The transport ship landed steadily on a relatively flat patch of ground at the edge of the valley.

The hatch opened, and the cold, thin plateau air rushed in.

Feng Yan was the first to step down the gangway, his team following behind.

Everyone was still wearing their personal Iron Wolf exoskeletons; these customized equipments had not directly taken part in the earlier battle.

But they ensured that the team could safely conduct technical command and data collection even at the front line.

In the distance, three Litigation Beasts stood like guardian deities at the center of the battlefield.

The Dragon Cavalry Guard's soldiers were systematically collecting weapons, detaining prisoners, and inventorying equipment.

Everything was in orderly fashion.

Wang Hao took a deep breath, then started coughing from the irritation: "Cough cough… this plateau air… is intense."

"Take it slow to adapt." Chen Guang calmly adjusted his exoskeleton's environmental control system.

Li Yang, meanwhile, could not wait to walk up to the nearest Litigation Beast—he wanted to get a close look at the mech's condition after combat.

Feng Yan stood in place, surveying the valley that had just undergone an asymmetric war.

The sunlight was just right, and the snow-capped mountains gleamed in the distance.

And yet, beneath this tranquility, within the seized communications equipment,

Within those data links already taken over by Torch Dragon but not yet fully shut down, a message that had undergone multiple encryptions was being sent in the most primitive short-pulse manner.

Toward a certain satellite direction, the final segment of information was sent:

【Mission failed. Encountered unknown mech unit. Technical gap cannot be estimated. Recommend initiating highest-level technology theft plan.】
