When I'm on the night shift, all the department heads can't sleep.

"Crackling and popping—!"

Beneath the torn tank of the tanker truck, deep blue flames spread wildly along the leaking phosphorus trichloride liquid, and the metal made a teeth-grinding twisting sound under the high temperature.

The gas alarms on the special operations team members had reached their maximum frequency, and their shrill beeping sound was like a death knell.

"Two and a half minutes left! The fire is about to lick the fuel tank!"

The special operations captain screamed into the anti-toxic walkie-talkie, his voice already completely shattered.

Inside the twisted and deformed driver's cabin of the bus, the space was so cramped it was suffocating.

The driver's carotid pulse was so weak it was almost undetectable, his chest had completely stopped rising and falling, and his pupils were rapidly and sluggish in their light reflex.

If oxygen supply is cut off in two more minutes, even if they are dragged out of the inferno, they will only be brain-dead vegetative patients.

"Fang Rui, don't look at the fire, look at his Adam's apple!"

Lin Ye's roar pierced through the noisy alarm, like a slap in the face to Fang Rui.

Fang Rui clenched his teeth, his eyes bloodshot from extreme tension.

He knelt on the footboard covered in broken glass, his right hand tearing open the sterile packaging of the cricothyroid membrane puncture cannula, while his left index and middle fingers, trembling slightly, quickly pressed against the center of the driver's swollen and cyanotic neck.

Thyroid cartilage...feel downwards...cricoid cartilage!

Between the two pieces of cartilage, the tiny depression that was almost filled by edematous soft tissue revealed an extremely blurry outline under the heavy pressure of Fang Rui's fingertips!

"Found it!"

Fang Rui roared inwardly.

"Insert the needle vertically, and immediately aspirate upon feeling a pullback; once air is detected, immediately push the cannula forward!"

Lin Ye gave a stern warning while lying prone deep inside the ruins.

"Sizzle!"

With a do-or-die determination, the thick puncture cannula was aimed at the upper edge of the cricoid cartilage and pierced vertically into the driver's neck skin!

The resistance vanished in an instant!

Fang Rui quickly pulled the syringe plunger—with a "whoosh," a smooth stream of gas, accompanied by a little pink foam, was instantly drawn into the syringe!

Air intake!

With his right thumb, Fang Rui decisively pushed the tubing down along the needle core, pulled out the metal puncture needle, quickly connected the portable high-frequency pressurized ventilation mask, and gripped the connector tightly with both hands, squeezing it forcefully!

"Whoosh—hiss!"

Pure oxygen was forced through the thin cannula, breaking through the spasmodic and closed glottis, and directly poured into the dying alveoli!

The bright red numbers on the pulse oximeter clip, which had almost become a straight line, suddenly jumped as if injected with a stimulant: 52%...65%...78%!

The driver's eyelids twitched violently, and his chest finally began to rise and fall again.

"It's open! Teacher Lin, the airway is open!"

Fang Rui was soaked to the bone and shouted through his mask.

"Step back, give me some light on your inner thighs!"

Lin Ye's voice was as cold as the ice of the far north.

Lin Ye had already tightly wrapped the second tourniquet around the groin, extinguishing the last pulse of the femoral artery, leaving the lower part of his right leg deathly pale.

The steel beam that trapped the driver was a special type of I-beam, which hydraulic shears couldn't cut at all. Amputation was the only way to save him!

"Administer 5 mg of midazolam and 0.1 mg of fentanyl intravenously!"

Lin Ye flung the special bone saw away, used his left hand to avoid the femoral artery and vein stumps and pressed down on the thigh, while his right hand ruthlessly slashed down with the scalpel!

The subcutaneous tissue and muscle groups were quickly pushed aside, revealing the stark white femoral shaft!

"Bone saw!"

Lin Ye threw away the scalpel, gripped the bone saw, and his arm veins bulged like a python.

"Sizzle—click! click!"

The ear-piercing, brutal sound of sawing bones echoed wildly inside the metal carriage! Bone fragments and blood splattered everywhere as Lin Ye's arms swung back and forth dozens of times per second, each downward press accompanied by a violent tremor of the hard bone cortex.

"Thirty seconds left! The fuse's about to explode! Run!!"

The special operations team members' stern shouts shattered the walkie-talkie.

The spreading blue toxic fire had burned through the rear tires of the tanker truck, and dazzling fireballs rose from the thick smoke!

"Cut it off right now!!"

Lin Ye let out a beast-like growl from deep within his throat, veins bulging on his arm, as the bone saw pressed down one last half inch—

"Snap!!"

A crisp snapping sound rang out! The strong femur broke in response!

Lin Ye swiftly retracted the bone saw, grabbed the thick, sterile tactical dressing, and tightly wrapped it around the severed limb stump. The pressure bandage was quickly wrapped and knotted tightly!

"The person is free! Pull!!"

Lin Ye grabbed the driver's belt, and Fang Rui and the two special operations team members pulled outwards with all their might, like a tug-of-war!

"Splash!"

The driver's body finally came off the deformed and twisted steering wheel, his broken right leg came off the steel frame, and he was dragged out of the front of the car!

"Get on the bus! Get on the bus now!!"

Two firefighters supported the driver's upper body, while Lin Ye and Fang Rui held the injured man's waist and limbs, working together to throw him onto the rear folding stretcher of the all-terrain four-wheel off-road motorcycle!

"Hold on tight!!"

The special operations captain slammed on the gas pedal, and the front wheel of the off-road motorcycle suddenly lifted off the ground. The four heavy off-road tires spun wildly on the slippery ground, gripping the ground, and roared like thunder as they sped away with the five people on their backs!

Just as the motorcycle had traveled less than twenty meters—

"boom--!!!!!"

A massive, unimaginably large, orange-red fireball suddenly rose up dozens of meters behind them!

The violent shockwave, accompanied by a toxic heat wave reaching hundreds of degrees Celsius, slammed into the motorcycle's rear fender like a prehistoric beast unleashed from its cage, carrying countless pieces of metal and windshield shards!

The entire vehicle swayed violently to the side, nearly overturning.

Lin Ye and Fang Rui clung tightly to either side of the stretcher, using their backs to shield the unconscious wounded from the flying debris and sparks!

Thick black smoke chased wildly behind, and the off-road motorcycle sped forward at almost blind speed in the smoke-filled tunnel, while abandoned vehicles on both sides flew backward like phantoms!

"I see light! The exit is ahead!!"

The shouts of the special operations team members, almost brought to tears, echoed inside their helmets.

"boom!"

The dazzling autumn sunlight, almost blinding, suddenly bathed my entire body!

Outside the tunnel's north entrance, billowing thick smoke, hundreds of anxious traffic police, road maintenance workers, and citizens kept at a distance by the cordon erupted in a deafening roar of screams and cheers the moment they saw the charred, flame-marked four-wheeled motorcycle burst out of the tunnel!

"They're out! They made it out alive!!"

"Quickly! Medical staff! Bring the stretcher!!"

The special heavy-duty rescue vehicle, which had been waiting at the scene, quickly slid to the side and opened its rear door wide.

Lin Ye removed his gas mask, which was already blackened by the thick smoke, and took deep breaths of fresh air. Together with Fang Rui, they transferred the driver from the motorcycle to the ambulance trolley and pushed it into the vehicle.

"Close the door! Back to the emergency department! Notify the orthopedics and interventional radiology departments to prepare for emergency repair and suturing; notify the blood bank to prepare eight units each of packed red blood cells and plasma!"

Lin Ye connected to the multi-parameter transport monitor while issuing commands.

The ambulance driver slammed on the siren and floored the accelerator, the ambulance whizzing through traffic and speeding toward the First Municipal Hospital.

Inside the carriage, Fang Rui slumped on the equipment box, panting heavily as if he had just been pulled out of the water. Looking at the driver they had rescued from the inferno, a faint smile of relief finally appeared on his pale face.

"Teacher Lin...we rescued him, we really did it..."

However, Lin Ye did not laugh.

His eyes were fixed on the screen of the transfer monitor that had just been connected to the bedside, and the hairs on his body stood on end in that instant!

On the screen, the previously steady sinus rhythm suddenly disappeared without warning.

Instead, the electrocardiogram showed towering, narrow, and massive malignant peaked T waves, resembling a tent! Immediately following, the QRS complex rapidly widened and distorted, like a giant python convulsing in death, instantly disintegrating into a continuous stream of extremely malignant rhythms—

[Ventricular tachycardia!!]

"Beep—beep—beep—!!"

The piercing, ear-piercing ventricular tachycardia alarm instantly tore through the carriage! The driver, who had been relatively calm, suddenly had his pupils dilate to the edges without warning under Lin Ye's gaze, and began to experience hypoxia-induced limb convulsions!

Fang Rui's smile froze instantly, his mind going blank: "How could this happen?! The tourniquet was applied perfectly!"

"It's not bleeding!"

Lin Ye grabbed the defibrillator's electrode pads.

"It's an extremely severe case of hyperkalemia caused by prolonged muscle compression! Toxins released from a large amount of dead muscle are flowing back into the heart via collateral circulation!"

Lin Ye smeared conductive paste all over the electrode plates, pressed his fingertips firmly against the 200 joule charging button, and his back was completely soaked with cold sweat in that instant.

"Defibrillator charge is 200 joules! Immediately administer 10 ml of calcium gluconate to counteract cardiotoxicity!!"
