Doomsday I Have A Super Survival System

Chapter 150

After dismissing the guy who was blocking the road, Kent and Philip got into the car, the caravan moved slowly, then gradually accelerated, and soon disappeared at the end of the road.

When they were far away, the person blocking the way looked down at the exchange order, and when he saw it, he immediately gasped.

The head guards were sucked to shrink a circle.

“It’s so expensive… It’s so dark…”

The man murmured, and then quickly looked around. After making sure that no one heard the words of own, he breathed a sigh of relief, then held the exchange slip in his hand, and ran to the north. There was a sewer where he officially walked when he came, and now he has to go back from here. .

Besides, Kent and Philip drove a small caravan all the way to the last gas station. But this time, they weren’t here to cheer, but they had agreed with Master to trade in this place.

But as the gas station got closer, Kent and Philip frowned.

Because they didn’t see any material piled up obviously.

Before leaving last time, everyone said well, this time we will come over and trade directly.

According to the understanding of ordinary people, if you want to trade, it must be prepared in advance. Although it is not certain when Kent and Philip will come over, since it is a lack of food and a desire for a deal, should they give full play to their initiative? Among other things, since Kent and the others left last time, shouldn’t they start preparing materials?

Now it’s no better than before. There are all kinds of convenient tools, and there are enough convenient transportation tools.

What happened to the survivors on Herto’s side, Kent and Philip actually don’t know much about it, but they don’t understand it anymore, and they can think of it with their big toes. Such a doomsday environment has experienced the impact of a nuclear explosion. I am afraid that there is only a little left. If only these vehicles are used for transportation, the capacity is absolutely very low. In order not to affect the transaction, is it a better choice to just collect the materials and stack them here?

They don’t believe that Master could not think of this. Even if the materials prepared are not enough, they are not at all.

Now this situation does not look like it is ready to trade.

Kent and Philip were wondering when they saw a head sticking out of the wall of the gas station. The other side looked at them and immediately put their heads back.

“Slow down and be ready to stop and fight at any time.”

Philip said immediately.

Ken Jun nodded and began to slow down the caravan.

Although they are not afraid, they are not reckless. They still need to be careful.

The speed of the small caravan was getting slower and slower, gradually approaching the gas station, and the speed slowed down, and finally stopped outside the gas station.

Neither of them was in a hurry to get out of the car, Philip squeezed the longbow, and Kent quietly held the submachine gun.

“Don’t get me wrong! I’m here to trade!”

Behind the wall, raised both hands, and then walked out alone.

Kent did not move, letting each other walk to the front of the car.

“Who are you? Where is Master?”

Philip asked.

“I’m Master’s companion, we met last time.”

The man replied.

Don’t even say the name?

Philip frowned.

“You haven’t answered my question yet, where did Master go?”

“He is sick, and he was recuperating in the shelter recently, so I have been waiting for you all this time. Is there food in the back? Can I see… Don’t worry, don’t worry, I won’t go there.”

As the man said, he was about to move forward.

Philip immediately raised his longbow, with the arrow in his hand, aimed at this person, ready to attack.

The man was frightened, and he took it back as soon as he took a step.

“What is Master’s disease? Shouldn’t he come out in person for such a big thing? Even if he is sick, he won’t prevent him from coming out.”

Philip asked again.

In fact, there is no need to ask this question. In theory, they can trade with anyone, as long as they can exchange enough materials.

But on the contrary, Philip did not like this situation where everything is out of control.

If the trading target is changed arbitrarily, it will not only waste time and energy, but also may change unexpectedly.

They are not afraid of death, they are worried that this kind of change will affect the material transaction.

“what–”

The man scratched his head when he heard the words, but it was a pity that he was blocked by protective clothing.

“I can’t say what the disease is, it’s pretty severe, and I don’t have much strength… But it doesn’t matter, does it? Anyway, you want metal materials, and we want food. As long as the materials are sufficient, there is no problem.”

“…”

Philip didn’t speak, but looked sideways at Kent.

Ken Jun nodded and spoke for the first time after entering Herto.

“The transaction can proceed normally, but I have not seen your materials.”

“Haha, we are all ready.”

The man opposite said with a smile, and then waved to the back.

Behind the wall, I don’t know when to stick out a head again. After seeing this person waving, several people immediately walked out behind the wall, two of them carrying a box and walking towards this side step by step.

It looks like the box should be quite heavy, but…

“Only one box of materials? Are you kidding me?”

Philip frowned more tightly.

“Don’t get me wrong, don’t get me wrong, what we brought out is not ordinary materials,” the man in the lead said, accompanied by his companions, and after putting the box down, he immediately opened the box and revealed the metal ingots inside, “Platinum, precious metals , The price is not cheap, and the industrial value is also very high. I know that ordinary steel materials can’t be exchanged for much grain, so I directly prepared more expensive materials. How about this? You always need this, right?”

The man said triumphantly.

He was right.

Platinum is indeed a precious metal, and its value is no less than that of gold, far exceeding silver.

Platinum can not only be used for the production of decorations, but also has a very high industrial value.

In this regard, the biggest use of platinum is to be a catalyst for chemical reactions, which is usually platinum black.

If An Kai is here, I am afraid I can still recall some of the knowledge I learned before. Platinum was used by chemists to catalyze the ignition reaction of hydrogen in the early 19th century.

The biggest application of platinum should be the catalytic converter of automobiles, which enables the complete combustion of low-concentration unburned hydrocarbons in the exhaust gas to produce carbon dioxide and water vapor.

In the petroleum industry, platinum can be used to catalyze several different reactions, especially the catalytic reforming of naphtha into higher-octane gasoline. Platinum dioxide is a catalyst for hydrogenation reactions, especially for the production of vegetable oils.

In addition, platinum metal can well catalyze the decomposition of hydrogen peroxide into water and oxygen.
