Seeing that his energy points were spent like flowing water, he couldn't help but feel very heartbroken, but at this juncture, he couldn't say that he had retreated like this, and now he just hoped that after killing all the zombies, he would take out all the corpse beads in their brains to make up for his purse.

Li Mobai walked out of the core space, took out these bullets from the carry-on space when everyone was not paying attention, put them all in the car, and then quickly drove the car to transport these ammunition to the point where the bullets were missing.

After everything was ready, Li Mobai came to the roof of the car again, and the zombie army at this time quickly killed him.

"Attention! Wait for the corpses to enter the second row of oil drums before shooting, and blow up all the oil drums," Li Mobai shouted loudly while standing on the roof of the car.

This was the first time he had given an order on the battlefield, and everyone who heard the order shouted "yes" in unison

"No. 3 and No. 4 shoot oil drums, and team No. 5 will prioritize killing mutant animals!" Seeing that the real power had entered the predetermined position, Er Jing immediately shouted loudly.

At this time, there were nearly 80 people on the battle line, and everyone fired together, and Li Mobai also took the blue flame Gatling and fired mercilessly at the corpses after Erjing's chanting.

After the 20 oil drums were set on fire, they exploded one after another, and the violent explosion sprayed the gasoline in the oil drums into a radius of more than ten meters, and the 20 barrels of gasoline instantly formed a sea of fire, mercilessly devouring all the lives that entered the fire.

Fierce flames and smoke rose into the sky, and everyone 300 miles away could feel that the temperature around them had begun to rise.

Several groups of mutant horses rushed out of the fire because they were too fast, and they rushed towards the blockade with fierce flames on their bodies, but they were broken into pieces by a dozen machine guns before they ran a few steps.

The sea of fire in front of him burned violently, and the corpses continued to pour into the sea of fire, the fierce high temperature burned all the zombies who walked into the fire into fire people, most of the zombies who were ignited on their bodies could not escape from the flame barrier that was more than 300 meters long and more than 50 meters wide.

Li Mobai saw that the method he inadvertently came up with was so effective, and immediately shouted to the people below, "Tang Xin!" Go and call your people, get as much gas as you want! Today I will burn 800 miles of company camps"

Tang Xin turned his head and said with some grievances: "Brother Li! Not really! I've emptied my family, and all this gasoline is actually exchanged from your base, so I really can't help it."

"Gas station! Tankers, diesel, kerosene and even cooking oil will do! As long as it can be lit, even if it's nail polish," Li Mobai yelled anxiously.

Tang Xin thought for a long time, and said aggrievedly, "It's really not, there is a gas station 6 kilometers to the west, and there is a fuel tanker truck in it, but the oil tanks have been drained by us."

Empty tanker! It's okay, after Li Mobai entered the core space to exchange for bullets just now, he looked at his remaining energy points, there are probably more than 2,000 points, one energy point can be exchanged for 10 liters of gasoline, or 15 liters of diesel, and more than 2,000 points can be exchanged for fuel It should be able to load half a car and a car.

"Two crystals! Wait until I'll get back, you know! After Li Mobai finished speaking, he jumped into the cab from the sunroof, and after starting the vehicle, he couldn't see the taillights in the blink of an eye.

Of course Erjing knew what Da Ge was going to do, he was going to find the empty fuel tanker, and then fill the oil tank, the power of the fire attack was indeed very unexpected, more than 20 barrels of gasoline could stop the progress of the zombie army, not to mention the power of a fuel tanker.

"Be careful to conserve bullets

！ Aim for the zombie's head, change all automatic rifles to single shots, and don't fire the machine gunner for more than three seconds! ”

Erjin didn't expect that the 150,000 rounds of bullets that came out had been exhausted in the first round of defense, and these 10 light machine guns were just like gluttony, consuming a large number of corpse beads, and just now Da Ge exchanged nearly 200,000 rounds of bullets, but until now, only 20,000 zombies have been shot.

Er Jing turned his head and saw that Qin Qian was still using the tablet, observing the movement of the corpse group, pondering for a moment, and then said, "Qin Qian!" The observer drones lowered their altitude and carefully searched for anything suspicious, I suspect they were being manipulated! Do you understand? ”

Li Mobai was driving on the road of the town, and suddenly thought of a problem, and immediately shouted loudly into the individual communicator, "Hey, hey! I'm number 1, do any of you know which fuel has the most burn value? Gasoline? Kerosene? Or diesel? ”

As soon as these words came out, the noisy report in the communicator immediately disappeared, and Li Mobai waited for a long time without getting the answer he wanted.

"It's terrible to be uneducated! Why don't you know how to read more! Li Mobai said helplessly in the communicator.

"You know!?" Erjin asked fiercely, and Li Mobai couldn't speak for a long time.

In fact, Li Mobai just wants to know which fuel has the largest combustion value, after all, different fuels are there, and the price in the exchange space is not the same, Li Mobai just wants to make full use of the remaining more than 2,000 energy points in exchange for the maximum combustion effect.

After Erjing finished scolding Li Mobai, he immediately shouted to his various squad leaders, "Are there any cultural people??? Who knows which fuel has the highest combustion ratio? Gasoline, kerosene, diesel, or even alcohol? Whoever can tell me will reward him with 500 corpse beads"

The question asked by Er Jing quickly reached the ears of the team members through the individual communicators of each captain, and a middle-aged man with glasses, an AK in his hand, and a somewhat thin figure immediately shouted "I! I! I know, I'm a physics teacher! ”

Zheng Xiao saw that among the 10 people he led, one of the middle-aged men raised his hand and shouted, and immediately brought him to Er Jing's side.

Seeing this middle-aged man standing in front of him with some restraint, Er Jing's expression immediately softened a little, and asked softly, "You are a teacher, can you tell me which of these fuels has the highest calorific value?" ”

After hearing the big leader's question, the middle-aged man immediately nodded and replied, "If it is liquid, gasoline can release 47.3 million joules per liter of combustion, diesel fuel can release 44.3 million joules per liter of heat, pure liquid alcohol can release 29.7 million joules per liter of combustion, and kerosene liters of combustion will release 42.7 million joules. ”

Hearing the middle-aged man, Er Jing slowly talked about the calorific value of these fuels like a few treasures, and had to admire this physics teacher, and just wanted to open his mouth through the communicator to tell Da Ge that the calorific value of gasoline is the highest, but the middle-aged physics teacher opened his mouth again.

"May I ask the leader, are you looking for fuel to burn zombies? Actually, I have a better way! ”

After Er Jing heard it, he immediately shook the middle-aged teacher's hand excitedly, "Say it quickly, what's the best way?" If it works, I can give you a request! ”

The middle-aged man scratched his already small hair, considered it carefully, and said, "In fact, burning these zombies does not need too high calorific value, the key is to burn for a long time, although gasoline has the highest calorific value, it also burns the fastest, leader!" If you can get asphalt, gasoline and a lot of metal aluminum powder, say they are mixed together in a ratio of 1:0.5:1, yes

After being loaded into a sealed tank, this is equivalent to creating a simple incendiary bomb, the calorific value of metal aluminum powder can be as high as more than 6000 degrees, the metal can be burned, and the asphalt burns the most durable, and even can be stained on the zombies, gasoline is an accelerant, used to assist the combustion of metal aluminum powder and asphalt, if you can get a ton, I estimate that it can be burned for more than half an hour"

The middle-aged man said all the thoughts in his heart in one breath, and then hesitantly added a sentence "Leader!" If you can't find the metal aluminum powder, you can just add gasoline and asphalt! ”

Of course, Erjin has heard of the famous incendiary bomb, this thing was used by the army when it fought against Vietnam, the fingernail covers so little fuel, as long as it is stained on the person, the flame can burn to the bones, and the more it shoots, the more vigorous it is, it cannot be extinguished at all, although these things add up to the effect of napalm incendiary bombs, but it is no problem to deal with these zombies.

"When the battle is over, you come to me!" Er Jing patted the middle-aged man on the shoulder, and then used the individual communicator to contact Da Ge.

"Number 1! Number 1! Please try to find asphalt, gasoline, metal aluminum powder, according to the ratio of 1:0.5:1 into the sealed tank! Make an incendiary bomb! ”

Asphalt, gasoline, metal aluminum powder! After Li Mobai heard these three things, he immediately knew what he was going to make, although he didn't have much education, but he often watched some military columns and some hardcore videos, as long as you use this thing properly, it is no problem to burn through the door of the vault.

"No. 1 understands, No. 1 understands, hold the line, I'll be back in 10 minutes!" Li Mobai had already arrived at the gate of the gas station at this time, and saw the elongated tanker truck at a glance, three steps and two steps, directly to the roof of the tanker, and the top of the tank cover was opened.

Seeing that there was no special situation around, he immediately entered the carry-on space, found the three things that Er Jing said, and saw the price of asphalt and aluminum powder, and almost turned Li Mobaile over, one energy point can be exchanged for more than 30 kilograms of asphalt, or 15 kilograms of aluminum powder, Li Mobai looked at his 2772 energy points, and began to do crazy mental arithmetic.

This oil tank is 130,000 liters of volume, if you just fill gasoline, it can hold about 15 tons, Li Mobai quickly calculated according to the capacity of the oil tank, he should exchange 5 tons of asphalt, 5 tons of aluminum powder and 2.5 tons of gasoline.

In this way, 5 tons of asphalt are only 170 points of energy, 5 tons of aluminum powder are 340 points of energy, 2.5 tons of gasoline are 250 points of energy, and the total price is only more than 700 points, Li Mobai feels that he has won the lottery, more than 700 points can be exchanged for 7000 bullets, these bullets can kill 500 zombies is good, but if you want to change this fuel to make a simple incendiary bomb, the effect is simply not too good.

Li Mobai immediately exchanged these three items and saved them in his personal space, and then put his hand into the empty fuel tank to fill the body, and directly released these three items together, saving even stirring at this time.

"Number 2! Number 2! The oil drum flame is about to be extinguished, and the zombies have broken through the flame zone! Su Bowen found that the fire in his right defense area was getting smaller and smaller, and a large number of zombies had rushed through the sea of fire, so he immediately commanded the team to concentrate fire and shoot to plug this gap.

"Shoot! Hold! 's coming back soon! Can't let these zombies break through the 200-meter defense! Erjin also noticed that the sea of fire in front of him was slowly getting smaller, and it seemed that it was really like what the physics teacher said just now, the higher the calorific material, the faster it burns.

Li Mobai also heard the situation ahead in the communicator, "Hold for 5 minutes, I'll be there in 5 minutes!" ”
