Apocalypse: My Items Upgrade Infinitely

The explosive power of gasoline far exceeds that of TNT under the same conditions.

In equal weight, gasoline explosions release ten times the energy of TNT! Even in the same volume, gasoline is six times more potent.

The 100 liters of gasoline Lin Feng held, if fully detonated, would be equivalent to a thousand grenades exploding simultaneously, equaling 1.5 tons of TNT.

More powerful than the 3-ton aerial bomb he witnessed on the battlefield, whose warhead was only 1.4 tons of TNT.

Enough to kill four to five hundred Black Spinal Bugs!

However, to completely vaporize barrel-stored gasoline and achieve the optimal air-oxygen mixture, precise and prolonged tuning is required.

Currently, there was no time for gasoline to gradually evaporate into the air, nor did Lin Feng know the technique, which only weapons researcher Ding Chenghai mastered.

But Lin Feng knew one thing for sure: liquid hydrogen evaporates much faster than gasoline!

Using it with gasoline creates a quickly-reacting explosive mixture, far more potent than mere gasoline combustion!

After all, this stuff is used in rockets.

Thus, he collected the hydrogen sacs from Red Armored Beetles, mixing them with gasoline to accelerate reaction rates and boost explosive power.

Lin Feng immediately opened the gasoline canister and inserted the hydrogen sac's nozzle.

As liquid hydrogen met the air, it began boiling, generating bubbles in the canister.

Hydrogen stirred the gasoline, speeding its evaporation!

With the deadly liquid bomb ready, Lin Feng timed his throw, discarding it on the road, with oil gushing from the unsealed spout.

Boiling hydrogen sped the gasoline's vaporization, and their similar densities allowed them to mix thoroughly with the air, spreading a pungent gasoline smell over the road.

A large, transparent, explosive vapor cloud formed over a few hundred square meters.

The camper was a kilometer from the insect swarm. Lin Feng shouted for Chen Yanyan to accelerate and widen the gap.

He didn't want the explosion's heatwave to topple their camper.

Currently, the Black Spinal Bug swarm chased at 60-70 mph, able to cover the kilometer to the gasoline canister in a minute.

Lin Feng gripped his Lv11 Explosive Gun, calculating the perfect shooting moment, needing to unleash a barrage of explosive rounds just as the lead bugs reached the gasoline canister, igniting the air's hydrogen-gasoline mix.

The crucial moment would pass in a blink, requiring impeccable timing.

Seconds ticked by...

Finally!

The leading swarm reached the gasoline canister. Lin Feng decisively pulled the trigger, unleashing a barrage of mini-explosives.

Now wasn't the time to save ammo; igniting the vapor wall was paramount!

Round after round flew from the muzzle, homing in on the Black Spinal Bugs in the explosive cloud.

In the next second, they detonated on the bugs' carapaces, igniting the internal powder with a reverse striker, creating a violent explosion.

The explosion's flames further ignited the surrounding hydrogen-gasoline mix!

Blue-red flames spread rapidly!

In a millisecond, the combustion reaction spread like lightning, forming a massive fireball over a hundred meters in diameter on the road!

The intense explosion's shockwave obliterated the central Black Spinal Bugs, and the swarm behind was knocked down, their joint weak points suffering varying degrees of damage...

The massive fireball rose, illuminating the entire suburb, but dissipated after several seconds, leaving behind wisps of smoke and steam.

Though the instantaneous power was great, the lack of a metal casing meant secondary damage was less severe than an aerial bomb's.

Still, it was quite a spectacle!

Two to three hundred Black Spinal Bugs lay sprawled, not dead but heavily injured.

The shockwave disrupted their sensitive central nervous systems, robbing them of balance and bodily control, leaving them twitching helplessly, unable to fight.

Following hundreds of Black Spinal Bugs, crossing their fallen comrades, were halted by a wall of flames on the road.

The massive flames had ignited the four gasoline drums.

The rapid pressure increase caused them to explode, spilling the remaining gasoline onto the road, creating a blazing firewall over ten meters wide.

The searing flames, reaching nearly two thousand degrees, forced the Black Spinal Bugs to retreat, their tough exoskeletons unable to withstand their innards being cooked.

For now, the firewall wouldn't extinguish.

By the time they circled it, the camper had vanished into the night.

Seconds earlier, Lin Feng had fired a barrage of explosives before ducking back into the camper.

Because real men don't look back at explosions!

Primarily, the explosion's shockwave could cause internal injury, even if outwardly unharmed, potentially rupturing organs.

Even with shield protection, Lin Feng wouldn't risk it unnecessarily.

After retreating inside, the explosion's shockwave reached them, but Chen Yanyan had floored the accelerator, putting two kilometers between them and the blast, greatly reducing the impact.

The high-speed vehicle merely shook, avoiding a rollover.

The burning fireball lit up the night, turning night into day for a few seconds before dimming.

Darkness reclaimed the land.

Lin Feng and Liu Yueqi looked back at the road's burning firewall, halting the Black Spinal Bug pursuit. They had escaped the swarm's clutches.

Not only saving themselves, but also countless survivors.

Of course, the explosion's far-reaching effects were spreading in ways Lin Feng couldn't fathom, shaping everyone's fate.

Lin Feng slumped into the passenger seat, calming his racing heart.

Thankfully, everything proceeded as planned, with no unexpected incidents.

Lin Feng knew from the start that relying solely on an Explosive Gun's firepower wouldn't suffice for swift upgrades and exterminating Black Spinal Bug armies.

Ding Chenghai had explained that Black Spinal Bugs, unlike resource-gathering Red Armored Beetles, defended territory and eliminated threats, rarely acting alone.

The smallest units, scout teams, consisted of at least three bugs.

Killing a few would summon hordes of Black Spinal Bugs, resulting in relentless pursuit.

Unless following Qin Hu's plan, using cars as bait to draw them to the perimeter, dispatching them, and retreating without engaging further.

Ensuring safety.

Thus, stable level grinding was impossible.

Only a hit-and-run strategy would work.

Slow and inefficient.

But that wasn't Lin Feng's style!

Go big or go home!

With the main battlefield's high intensity drawing attention, the Empress's divided focus left the flank vulnerable, perfect for annihilating a swarm!

Gasoline and hydrogen sacs inspired Lin Feng.

Four gasoline drums, used right, could devastate a Black Spinal Bug army.

"Shall we go back?"

Chen Yanyan eased the speed, wary of nighttime accidents from prolonged high-speed driving.

Lin Feng shook his head:

"The Black Spinal Bug army has five to six hundred bugs. The explosion's power seemed great, but it only killed a few dozen at the center. The rest are merely injured, with more behind unaffected..."

"Going back would be suicidal. Surviving this is a win."

Despite his words, Lin Feng eyed his Explosive Gun:

"Lv11 Explosive Gun, Red Quality"

"Upgrade Points: 21/3, Damage: 60, Effective Range: 2 km, Remaining Ammo: 55/300"

The gasoline explosion yielded rich rewards, killing 21 Black Spinal Bugs.

Lin Feng suspected the actual number was higher, with many bugs dying from injuries later, but unrelated to the gunshot, thus uncounted.

If he'd shot more, he'd gain more upgrade points, but risked reigniting the surviving bugs' wrath...

A futile effort.

Lin Feng lacked extra gasoline and confidence for another miracle explosion.

The 21 upgrade points sufficed for now, allowing gradual upgrades to Lv15.

Doubling explosive power.

Next time, facing a swarm wouldn't be as frantic, needing every trick to escape pursuit.

Seeing a toll station ahead, Lin Feng finally relaxed, initiating an Lv12 upgrade for his Explosive Gun.
