End of the World: My Items Can Be Upgraded Infinitely.

Chapter 37 Art is explosion!

The explosive power of gasoline is actually far greater than that of TNT high explosives of the same unit.

With the same weight, the energy generated by gasoline explosion is ten times that of TNT explosives! And with the same volume, there is also a six-fold difference.

If the 1.5 liters of gasoline in my hand were completely burned, the power would be comparable to that of grenades exploding at the same time, which is equivalent to tons of TNT explosives.

This was even more powerful than the three-ton aerial bomb that Lin Feng had witnessed when he accidentally broke into the front battlefield, because its warhead was only 1.4 tons of TNT.

But it is enough to kill four or five hundred black-backed insects!
However, in order to allow the barreled gasoline to completely evaporate into the air and achieve an optimal mixing ratio with oxygen, precise and long-term debugging is required.

Under the current circumstances, there is obviously no time to let the gasoline evaporate slowly into the air. Besides, Lin Feng doesn't know how to do it. Only Ding Chenghai, who studies weapons, knows how to do it.

But Lin Feng can be sure of one thing, that is, the evaporation rate of liquid hydrogen under normal conditions is far greater than that of gasoline!

Use it in combination with gasoline to create a fast-reacting explosive mixture that is far more powerful than burning gasoline!
After all, this thing is used in rockets.

That's why he collected the hydrogen storage capsules in the red beetles' bodies, mixed them with gasoline, increased the reaction rate, and enhanced the power of the explosion.

So Lin Feng immediately opened the lid of the gasoline barrel and then stuffed the tube of the hydrogen storage bag into it.

The liquid hydrogen inside came into contact with the air and gradually boiled, with a large number of bubbles gushing out of the oil barrel.

The hydrogen is stirring the gasoline, speeding up its evaporation!

After preparing the terrifyingly powerful liquid bomb, Lin Feng seized the opportunity and threw it directly on the road. Oil oozed out of the unsealed barrel mouth.

The boiling hydrogen accelerates the volatilization of gasoline. The two have similar densities and after vaporization, they are fully combined with the air. The pungent smell of gasoline spreads above the road.

A transparent and explosive mist covering hundreds of square meters was formed.

At this time, the RV was still one kilometer away from the black-spined worm tide. Lin Feng yelled and asked Chen Yanyan to speed up and create a farther distance as soon as possible.

He didn't want the entire RV to be overturned by the heat wave generated by the explosion.

At present, the pursuit speed of the black-spined worm tide has exploded to sixty or seventy yards. At a distance of one kilometer, they can reach the gasoline barrel dropping point within one minute.

Lin Feng held the level 11 grenade launcher in his hand, calculating the best time to shoot. He needed to wait for the dozen or so black-backed insects at the front row of the insect tide to reach the gasoline barrel, and then pour a large number of explosive bullets to let the flames from the impact ignite the hydrogen-oil mixture in the air.

The critical moment is fleeting and must be just right.

Time passes by second by second...

at last!

The vanguard of the insect swarm arrived in front of the gasoline barrel. Lin Feng decisively pressed the trigger and continuously fired small explosive bombs.

There is no time to save bullets at this time. Detonating this explosive gas wall is more important than anything else!

Bombs were fired one after another from the muzzles as if they were free, flying towards their targets and breaking into the swarm of black-backed insects in the explosive mist.

The next second, they exploded on the surface of the giant insect. The reverse firing pin in the warhead ignited the granular explosive stored inside, which burned violently and exploded.

The flames produced by the explosion further ignited the surrounding hydrogen-oil mixture!

The blue and red flames spread rapidly!
Within one thousandth of a second, the combustion reaction spread like lightning, forming a giant fireball with a diameter of over 100 meters above the road!
The shock wave generated by the violent explosion directly shattered dozens of black-spine insects in the center, and the insect tides nearby and behind were also knocked to the ground. The weak parts of their limbs and joints all suffered varying degrees of damage...

A huge fireball rose up, illuminating the entire suburbs, but it only lasted for a few tens of seconds before disappearing, leaving only a little black smoke and water vapor.

Although the instantaneous power is great, the secondary damage caused by the explosion is not as serious as that of an aerial bomb because it is not wrapped in several layers of iron sheets.

But even so, it was quite shocking!
As many as two or three hundred black-backed insects collapsed to the ground in large groups. Although the aftermath of the damage did not kill them, they were seriously injured.

The shock wave destroyed the weak central nervous system in their brains, causing them to lose their sense of balance and body perception, staggering and twitching, and losing their ability to fight.

The hundreds of black-backed insects following behind, after rushing through the pile of corpses of their companions, were blocked by the blazing wall of fire on the road.

The huge flames also ignited the four barrels of gasoline.

They exploded due to the sudden increase in air pressure, spilling the remaining half barrel of gasoline onto the road, igniting a blazing wall of fire more than ten meters wide.

The fire raged, the heat waves surged, and the temperature reached nearly two thousand degrees. Even the black-backed insects had to retreat. No matter how strong their outer armor was, it could not withstand the roasting of their abdominal organs.

And for a while, this wall of fire could not be extinguished.

By the time they had gone around both sides, the target RV in front had disappeared into the darkness.

Ten seconds ago, Lin Feng fired a series of explosive bombs and then went straight back into the RV.

Because a real man never looks back at an explosion!

The main reason was the shock wave from the explosion, which could cause bleeding in the fragile flesh and internal organs. Although it might look fine on the surface, the internal organs might have been shattered. Even with the protection of the shield, Lin Feng didn't want to waste time and take risks on this.

After he retreated into the car, the shock wave generated by the explosion rushed to him. Fortunately, Chen Yanyan stepped on the accelerator in advance and accelerated madly, creating a long distance of two kilometers from the explosion point, which greatly reduced the damage suffered.

The car body, which was traveling at high speed, only vibrated a little but did not tip over.

The huge burning fireball illuminated the entire night, and the earth was as bright as day, but it only lasted for a few seconds before gradually dimming.

Night covered the earth again.

Lin Feng and Liu Yueqi looked back and saw the burning wall of fire on the road, which blocked the black-backed insects from continuing to pursue them. They successfully escaped from the clutches of the insect tide.

Not only did he save himself, but he also saved thousands of survivors.

Of course, the far-reaching impact of this explosion is still spreading rapidly in ways that Lin Feng does not know, affecting the fate of everyone.

At this moment, Lin Feng sat down on the passenger seat to calm his violently beating heart.

Fortunately, everything went according to his original plan and progressed smoothly.

Long before participating in the mission, Lin Feng realized that if he wanted to quickly complete the upgrade and eliminate the hordes of black-spine insects, the firepower of a grenade launcher alone would be far from enough!

Ding Chenghai once said that black-backed beetles are different from red beetles that scatter around to collect resources and food. Their duty is to defend their territory and eliminate enemies, so they basically will not be left alone.

The smallest combat unit, the scout squad, has at least three or more members.

After killing a few more times, it will attract swarms of black-backed insects, and then they will chase you madly.

Unless, as Qin Hu planned, he used several cars as bait to lure the enemy to the edge of the activity territory, and then left directly after dealing with them, without any lingering battle.

This is the only way to ensure your own safety.

Therefore, it is basically impossible to level up steadily.

You can only fire once and then quickly move to another place.

Slow and inefficient.

But this is not Lin Feng's style!

If you want to play, play big!

Taking advantage of the high intensity of the front battlefield to attract firepower, the Queen Mother is too busy to take care of the flanks and fiercely annihilate a group of black-backed insects!
The gasoline and hydrogen storage bags gave Lin Feng inspiration.

Four barrels of gasoline, if used well, are enough to defeat the army of black-backed worms.

"Want to go back and take a look?"

Chen Yanyan slowly slowed down the car. Driving at high speed in the dark is prone to accidents. Sprinting for a short period of time is fine, but accelerating all the time is playing with your life.

Lin Feng shook his head:
"There are at least five or six hundred black-backed insects in the army. The explosion just now seemed powerful, but only a few dozen black-backed insects were completely killed in the center of the explosion. Those that fell to the ground were only seriously injured. There are more black-backed insects in the back, just like the RV, they were not affected by the explosion..."

"Going back now would mean death. It would be good enough if we can save our lives."

While saying this, Lin Feng looked at the grenade launcher in his hand:
「LV11 Bolt Gun, Red Quality」

「升级点：21/3，伤害60，有效射程2千米，剩余子弹55/300」

The successful implementation of the gasoline explosion plan brought him rich rewards, directly killing 21 black-backed beetles.

But Lin Feng estimated that the actual situation was far more than that. Many black-backed insects were seriously injured and died after struggling for a while, but their death from serious injuries had nothing to do with the bullets fired, so they could not be counted.

If I fire a few more shots later, I might get more upgrade points, but that would also arouse the hatred of the surviving black-spine insects again...

The result is more trouble than gain.

Lin Feng does not have the extra gasoline or confidence to stage another miracle explosion.

At present, there are as many as 21 upgrade points, which are enough for Lin Feng to use for a while to gradually upgrade the grenade launcher to level 15.

By then, the power of the bomb can almost double.

Next time when facing a swarm of black-spined worms, I will not flee in such a miserable manner as I am now, using all means to escape pursuit.

Seeing the highway toll station appear in the distance, Lin Feng breathed a sigh of relief and then upgraded the grenade launcher in his hand to level 12.
