389: Chapter 389 Chemical Cleaning Agent in the Tin Can

"Hiss—!!!"

The piercing sound of high-pressure gas being released exploded simultaneously from three corners of the safe house!

It was not a flashbang. Nor was it a high-explosive grenade.

A plume of dense, strangely yellowish-green smoke, carrying the strong scent of bitter almonds, surged like three venomous pythons, beginning to frantically devour the oxygen inside the safe house within just a few seconds!

"It's a 'cleanser'! Hold your breath! Get down!"

Chen Mo's voice exploded in the darkness like a thunderclap, losing its previous composure and revealing a rare, chilling sharpness.

That was a mixture of military-grade nerve gas and high-concentration tear gas!

Inside this "iron can" fifty meters underground, with the ventilation system completely locked down, this chemical cleanser would only need two minutes to cause the alveoli of those inside to rupture, leading to death by suffocation!

In the blind spot, although Captain Zhao Tie's mouth was covered by Su Qingxue, that pungent bitter almond scent still managed to drill its way into his nasal passages.

"Cough... ugh!"

Having inhaled only a trace of the gas at the edge, Captain Zhao Tie's strong body instantly began to spasm violently.

His eyes were bloodshot, and tears gushed out uncontrollably.

A painful wheezing sound like a broken bellows emitted from his throat, and he almost broke free from Su Qingxue's restraint.

"Don't move! Don't breathe!" Su Qingxue's eyes were red, and she pressed Captain Zhao Tie firmly to the ground.

She quickly tore off a piece of her sleeve, soaked it forcefully in the water pooled on the ground, and forcibly covered Captain Zhao Tie's mouth and nose.

At the same time, she held her own breath, pressing her face against the cold concrete floor, searching for that tiny bit of pitiful oxygen at the very bottom.

The air quality inside the safe house was deteriorating at a speed visible to the naked eye.

Chen Mo quickly tore off a piece of fabric to cover his mouth and nose.

The toxic gas could deprive him of his sense of smell, irritate his tear glands, and even interfere with his breathing. But... it could not obscure the 【Heartbeat Localization】 in his mind!

"Switch to thermal imaging armor-piercing rounds, indiscriminate fire."

Outside the door, the Priest's cold command penetrated the gas.

"The heat in their lungs will rise sharply under the stimulation of the gas. In thermal imaging, they are like torches in the dark. Open fire!"

"Rat-tat-tat-tat-tat-tat!!!"

The deafening sound of automatic rifle fire tore through the darkness like a violent storm!

Three assault rifles equipped with thermal imaging scopes poured large-caliber armor-piercing rounds frantically through the half-meter-wide gap!

The most lethal part was not a direct hit.

Inside this all-steel safe house, which was no more than ten meters in length and width, the armor-piercing rounds, unable to penetrate the titanium alloy walls, would create terrifying ricochets!

"Whiz—clang!" "Whiz—clang!"

Countless scorching bullet heads bounced frantically between the walls, ceiling, and floor, drawing lines of blinding sparks.

The entire safe house instantly turned into a meat grinder filled with deadly stray bullets!

"Ah!" Captain Zhao Tie let out a scream.

A ricocheting bullet grazed his calf, instantly tearing off a large chunk of bloody flesh.

If it weren't for Su Qingxue holding him down tightly, he would have jumped up in pain and been shot to death long ago.

Chen Mo's figure weaved through the gas and stray bullets like a ghost.

His brain was operating frantically; the 【Heartbeat Localization】 radar not only locked onto the four people outside the door, but even predicted the initial trajectory of the bullets 0.5 seconds in advance based on the slight acceleration of their heartbeats when they pulled the triggers!

Every one of his dodges landed exactly in the blind spots of the bullet ricochet paths.

But he knew he couldn't hold on for long. The concentration of the gas had reached a critical point.

He felt as if his lungs were burning, and his vision began to double due to oxygen deprivation. He had to break the deadlock!

"Nightingale!" Chen Mo issued a low roar amidst the dense gunfire, using a secretive tactical throat sound.

"Seven o'clock direction, edge of the ceiling. Manual exhaust valve. Two seconds, smash it!"

Above the dark dome, Nightingale, who had been clinging to the ceiling beam like a gecko, had a flash of chilling cold light in her eyes.

She had already held her breath for over two minutes, her cheeks flushed with a sickly pallor from holding her breath. But her hand holding the knife remained as steady as a rock.

Hearing Chen Mo's command, Nightingale kicked off the beam with her legs.

Her whole body, like a diving black swift, folded impossibly in the hail of bullets, dodging a set of lethal ricochets.

"Snap!" In mid-air, the broken blade turned into a silver bolt of lightning, piercing fiercely into the manual exhaust control valve on the wall that had been locked by a code!

Sparks flew everywhere! The sturdy electronic valve was directly ripped out by the roots by Nightingale's terrifying explosive power!

"Rumble—" As the valve was physically destroyed, the safe house's backup emergency exhaust system let out a muffled roar, and the huge exhaust fan began to run frantically.

The yellowish-green toxic gas inside the safe house, like a tide caught in a whirlpool, surged rapidly toward the exhaust vent on the ceiling. Her vision cleared slightly.

Outside the door, the Priest saw the movement at the exhaust vent through thermal imaging.

"They destroyed the exhaust valve! Suppressive fire on the left blind spot! Number Two, Number Three, prepare to breach!" The Priest's tone finally showed a hint of impatience.

The opportunity had arrived.

At the moment the toxic gas dispersed slightly, Chen Mo performed a standard tactical roll and slid to the side of the Clown's corpse.

His fingers precisely felt for another spare glock 18 fully automatic pistol in the pool of blood.

The metal grip of the pistol was covered in the Clown's sticky blood. But the moment Chen Mo grasped it, the aura around him underwent a heaven-shaking change.

He was no longer the prey dodging stray bullets. He was the Grim Reaper who had opened his eyes.

"Priest." Chen Mo half-crouched on the ground, his thumb skillfully flicking the full-auto switch of the glock.

In his mind, the 【Heartbeat Localization】 radar net locked tightly onto the two red dots approaching the gap, as well as the Priest standing behind them, attempting to provide cover fire.

He slowly raised the muzzle, aiming at the 1.2-meter-thick titanium alloy door panel. Not at the gap, but at the solid door panel.

"Your physics is not bad; you know that armor-piercing rounds will create ricochets in a confined space."

Chen Mo's cold voice penetrated the roar of the exhaust fan, like the whisper of the Grim Reaper.

"Then guess, if you shoot into a half-meter-wide flared opening, what is the refraction rate of the reverse ricochet?"

"Bang bang bang bang bang bang!" Chen Mo pulled the trigger all the way!

The bullets in the 33-round extended magazine were completely emptied within two seconds!

The bullets did not pass through the gap to fire outside. Instead, they struck the edge of the titanium alloy steel plate inside the gap at a weird, tricky, oblique angle!

"Clang, clang, clang, clang!"

Under the terrifying kinetic energy and the principle of geometric refraction, dozens of bullets instantly changed their trajectories. Like a great net of death spreading outward, they ricocheted frantically out through the half-meter gap, following a radial trajectory toward the passage outside!
