You must know that even if it is an ordinary "gas tank" explosion, there will be two damages in an instant, starting with the rupture of the tank and a physical explosion, and the liquid petroleum gas instantly expands 25o~3oo times into a gaseous state, producing a shock wave, like a mine explosion. When the concentration in the air drops to 3~11%, in case of open flame, it will produce a chemical explosion, and the entire gas space will explode and burn, producing a huge shock wave, injuring lives, burning property, destroying buildings, and bringing secondary disasters.

What's more, it is known as one of the pure energy sources of natural gas methane, which is lighter and flammable than coal gas, and the content of natural gas in the same volume is larger, and the power of the explosion cannot be underestimated, thinking of using natural gas canisters as grenades, Lin Hong must not be the only one who has thought about it, but the huge sound caused by the explosion of this thing will attract more zombies, and the purpose of those hunting teams is just to search for supplies. And the slums and shantytowns, all the relief food that comes to eat, where is there extra food? As a result, these gas tanks are idle and no one patronizes them. Looking at the room full of natural gas tanks, Lin Hong's heart was moved, and he stopped, and Chef Wei and Qin Keyu followed Lin Hong for some reason.

When the boss saw Lin Hong's stunned appearance, he looked at the other party's clothes again, and immediately knew that the other party must have a heart to buy it, so the boss with a dish on his face immediately greeted enthusiastically: "How is it?" Boss, look at it, this natural gas tank is all new, and you see, it has not been used, it is guaranteed to last for three months, and more importantly, it can boil water in the natural gas tank, and take a hot bath, how good it is......"

Seeing that Lin Hong didn't react, she could only say in a smug voice: "A natural gas tank is worth at least 3o grams of gold, since you want it, just give 25 grams." ”

Lin Hong was a little moved, this price is not very expensive, and if it is approved, the price should be lower, but Qin Keyu next to him said, and said to the proprietress: "25 grams of gold, you go and grab it, two and a half catties of rice, do you think it is a big road goods, how many people are hungry now and can't walk, how can they have extra energy to cook and cook, and boil water for a bath, that is even more extravagant, we have a rich area, there is a supply of tap water and gas pipelines, and the water resources are so tight that we are reluctant to wash it once every two weeks!" ”

Qin Keyu bargained without blinking, and stretched out his delicate little fist: "1o grams of gold, if we can, we can make a deal now, if you can exchange one pound of rice, you can exchange it for more than thirty black-flour steamed buns, right?" When the boss saw that it was food, he was a little tempted, and couldn't help but swallow his saliva, this catty of rice can indeed be replaced with a lot of black-flour steamed buns, at least two weeks without starvation, but Qin Keyu's bargaining price is too low, holding the psychology that she can catch some is some, she shook her head and said: "The price is still too low, 15 grams of gold, 15 grams will be sold!" ”

Qin Keyu waved his hand and said, "The price of 15 grams of gold is still slaughtering, as far as you are a natural gas tank that is not a necessity for life, I'm afraid that if you miss us as a buyer, it will be difficult for you to meet the next one, right?" And you're not the only one in this trading market, right? You don't want to be a tiger, as far as I know, Xinghua Road in South Street and Zhongyuan Road in West Street are sold, and the price is about the same as yours here, if you don't agree to sell, we will have to run a little more, I think they should be happy to call, but you will miss a deal. This sentence obviously talked about the boss's sore spot, she was obviously taken aback by Qin Keyu's understanding of the trading market, and couldn't help but think about it, gritted her teeth and said: "Okay, okay, 1o grams is sold!" ”

Qin Keyu happily turned around and compared a scissor hand to Lin Hong, who was a little stunned, glanced at Lin Hong with his eyebrows, quietly came to Lin Hong's side, and said proudly: "How is it, uncle, Miss Ben's bargaining skills are still very good, right?" ”

Lin Hong smiled and touched his nose, thinking that 25 grams of gold was a big bargain, but he didn't expect Qin Keyu, a temporary tour guide, to cut off more than half of the price as soon as he opened his mouth, and let Lin Hong pick up a big bargain.

"You're great, but you're ignoring my true intentions." Lin Hong smiled and said.

"Huh? What is the intent? Qin Keyu was stunned and couldn't help asking.

"Boss, I want all the gas tanks you have here." Lin Hong opened his mouth and said, Chef Wei, who was helping to carry the natural gas canister, was suddenly stunned, Qin Keyu looked at Lin Hong dumbfounded, as if he had seen an alien, and even the boss was stunned, looking at the twenty cans of natural gas in his store in disbelief, and then immediately showed a surprised expression on his face.

His voice trembled a little and shouted, "This big boss...... You—Are you really going to buy them all? ”

"Well, you have to find someone to transport me to the shantytown house in District 5o, the largest house is my address, all of them will be transported there, and I can give you the money first." Lin Hong nodded without hesitation, took out two gold coins from his waist bag and pressed them on the container, the boss suddenly blushed with excitement, and was speechless with joy, nodded vigorously, and quickly pinched the two gold coins on the container in his hand, and bit it in disbelief, almost broke her teeth, and finally she was ecstatic and almost shed tears.

Nodding vigorously and guaranteeing, he said excitedly: "Boss, don't worry, twenty cans of natural gas are absolutely ten percent new, to ensure the quality, now I will immediately leave for you to find someone to transport it over, to ensure that Tong Su is not bullied!" I also have a lot of daily necessities here, toothpaste, toothbrushes and lotions, all of which are unpacked, and they are all shipped to you, even if they are gifts! ”

"Boss, even if you get some natural gas tanks to cook and boil water, there's no need to spend so much, isn't it a bit of a waste to buy so much in one go?" Chef Wei looked resentful, and watched the two gold coins flow out like this, in his opinion, those were all white rice, and he had experienced the pain of starvation, but his aching teeth were trembling.

Qin Keyu couldn't help but widen his apricot eyes, his face was amazed and shocked, and then he was excited in his heart, this uncle is really Kaizi, he spent two hundred grams of gold in one go, he didn't blink his eyes, he was so generous, he would show it well later, and maybe he could get more tips when he was done!

"It's okay, I have my own plans." Lin Hong said with a sloppy look.

"Boss, please stay, take a look, as long as 1o grams of gold, the price of a pound of rice, you can take everything I have here!" Batteries, chargers, all kinds of high-end mobile phones, and even satellite phones and receiver antennas ......"

Just when Lin Hong was about to come out, the shopkeeper next to him couldn't help but shout, it was really the income of the shopkeeper next door who was red at this time, Nima, two gold coins, how much grain can this be exchanged for? I'm afraid I won't have to go hungry for half a year, he who is already hungry with his chest against his back, he exclaimed excitedly.

If you miss Lin Hong's big money, I'm afraid you won't be able to find a buyer in the future.

Lin Hong didn't plan to deal with it, but as soon as he heard about the battery supply and satellite phone, he suddenly felt a little moved, and it didn't take much effort to step on the iron shoes and find nowhere to get it, so he turned his head and went to the store next door, where all kinds of electronic equipment were available, brand-name mobile phones, maintenance parts of major brands of computers, chargers and antennas, but in the last days, this kind of small self-employed maintenance work has been on the verge of elimination, and the small shop pù doesn't know how long it has not been a buyer, and there are cobwebs in some empty places.

"The boss is good, as long as there is a pound of rice, the boss will carry everything away!" The young man with sunken eye sockets said excitedly. "Give me all the lithium batteries for the satellite phone, I just lack some." Lin Hong put a golden bean on the counter, the young man was suddenly excited, his palm trembling because of hunger groped for a lot of parts, and soon found the battery with the matching model, and skillfully installed it for Lin Hong, the screen on the surface of the black box of the satellite phone quickly lit up, and more than forty missed calls were displayed at once, Lin Hong suddenly broke out in a cold sweat, and eighty percent was called by Yang Yun's girl.

Lin Hong suddenly had a very bold idea in his heart, whether he could rely on the high-tech communication level of Loongson No. 1 to connect a large number of satellite phones to the private network, so that it would be much more convenient for Lin Hong to contact other people, and now that the mobile phone signal has been completely blocked, timely communication of information exchange is particularly important, especially when going out for a wide range of hunting, timely contact is very important, and Lin Hong is not a member of the military, It is obviously wishful thinking to have a network of military satellites, but with Loongson 1, this qiē may not be empty talk!

"Your Excellency, your understanding is somewhat biased, the satellite communication system is composed of two parts: the space part - the communication satellite and the ground part - the communication ground station. In this system, the communications satellite is effectively a communications relay station suspended in the air. It is condescending and has a wide field of vision, as long as it is within its coverage and irradiation area, it can communicate regardless of distance, and it can turn and reflect wireless signals such as telegraph, television, radio and data. In layman's terms, the ground shoots a wireless signal, which is transmitted by the satellite and then transmitted to the receiving location in another place on the ground, and a satellite can cover half the earth, so the communication of the satellite phone is very convenient and not easy to be interfered with. Dandan explained in Lin Hong's mind.

Lin Hong's heart was half cold, and he couldn't help asking: "Do you mean that if you can't operate an independent private satellite, you can't achieve satellite communication?" However, if you want to apply to join the military's military satellites, not to mention how much you have to pay to join them, no matter what actions and intelligence you have in the future, they will be monitored and eavesdropped everywhere, and even if you have satellite communications, what is the use? ”

(Lin Hong's time to pretend to be 13 yin people is coming soon, and it is currently preparing for the accumulation stage, brothers, all kinds of tickets are piled up~~~ Today's two shifts are over!) ）
