Chapter 149： misfortune

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.

Waiting for them to go far, the person blocking the way looked down at the exchange order, and when he saw it, he immediately gasped.

The head shields were all sucked and shrunk in 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 what he said, he breathed a sigh of relief. Then he 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. .

Let's talk about Kent and Philip, driving a small caravan all the way to the last gas station. But this time they didn't come to cheer up, but they had agreed with Master before to trade in this place.

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

Because they didn't see any obvious piled up materials.

Before leaving last time, everyone said well, this time they 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 to trade, 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 is no better than before, there are various convenient tools, and there can be enough convenient transportation tools.

What happened to the survivors on Herto’s side, Kent and Philip actually didn’t know much about it, but if they didn’t understand it, they could think of it with their big toes. Such an apocalyptic environment, and experienced the impact of a nuclear explosion, left the rest of the city. 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 they don't have enough materials, they won't have none at all.

In this situation, it doesn’t look like it’s ready to trade.

Kent and Philip were wondering, 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 Feature nodded and started to slow down the caravan.

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

The caravan's speed became slower and slower. It gradually approached the gas station, and its speed slowed down. Finally, it stopped outside the gas station.

Neither of them rushed to get out of the car, Philip pinched 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 here for you all this time. Is there food in the back? Can I see... Don’t be nervous, don’t be nervous, I won’t go there."

The man was about to move forward while talking.

Philip immediately raised his longbow, the arrow was already pinched in his hand, and he aimed at this person, ready to attack.

The man was frightened, and he took it back as soon as he stepped out.

"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.

Actually, 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 doesn't like this situation where everything is out of control.

If the transaction target is changed randomly, 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, but it's pretty severe, and I don't have much strength... But it doesn't matter, does it? Anyway, you want metal materials. We want food. As long as the materials are sufficient, it will be okay."

"..."

Philip did not speak, but looked sideways at Kent.

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

"The transaction can proceed normally, but I did not see your materials."

"Haha, we are all ready."

said with a smile on the opposite person, and then waved to the back.

Behind the wall, I don’t know when I poked out another head. After seeing this person waving, several people walked out from behind the wall. Two of them carried a box and walked towards this side step by step.

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

"There is only one box of materials? Are you kidding me?"

Philip frowned even more.

"Don't get me wrong, don't get me wrong, what we brought out is not ordinary material," the man in the lead said, UU reading www.uukanshu. Com came to him with his companions. After putting the box down, he immediately opened the box and revealed the metal ingots inside. "Platinum, precious metals, is expensive, and its industrial value is also very high. I know that ordinary steel materials can’t be replaced much. Food, so I directly prepared more expensive materials. How about this? You always need this."

The man said triumphantly.

He was right.

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

Platinum can not only be used in 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 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.
