Evening.

The street lights in the central city are lit up, dotted with a steel city.

Although compared to the brightly lit floating city, the steel city seems a little small.

But at night, the central area is still full of traffic, and the night market is very lively.

After Chen Ya walked out of the subway station, he came to the door of the wasteland bank.

However, I saw that it was a luxuriously decorated financial institution, and the logo of the main gate was the pattern of 'Golden Earth + Floating City'.

The specific name is:

【HWB-Human Wasteland Bank】

Wasteland Bank is a neutral financial institution.

Whether it is in the Human Federation or in the camp of the Freedom Alliance, as long as there is a floating city, there must be a wasteland bank.

Chen Ya walked into the bank and immediately saw a simulated robot in a suit.

The reason why it is said that the other party is a robot.

The reason is simple.

There is no emotion in the suit android's eyes, while there is also a button-sized blue circle on the left side of the forehead.

This is the hallmark of artificial intelligence.

But seeing that the android who was a staff member saw Chen Ya and immediately spoke:

"Welcome to Wasteland Bank, what do you need to do?"

"Withdrawals."

Chen Ya said, and the android stretched out his hand and said:

"Please show your bank magnetic card."

"Forehead ......"

Chen Ya couldn't cry or laugh, the system didn't give him a magnetic card, so he could only shake his head helplessly:

"I lost my magnetic card, can I report the card number?"

Hearing this, the android nodded:

"Please state your card number and we will verify your account information."

……

More than ten minutes later.

Chen Ya walked out of the wasteland bank, with ten more wasteland coins with a denomination of 1,000 in his hand, as well as a pure black magnetic card.

This is a bank card he has just applied for.

Looking at the card colors, it seems to be very advanced.

It can also be seen from the side that the system is still very awesome.

After collecting the magnetic card, counting the two thousand yuan that he had to buy the shed, Chen Ya had 12,000 waste earth coins in hand.

This is undoubtedly a huge amount of money for children.

"It's still too little."

Chen Ya shook his head, and then went straight to the wasteland market.

However, although it is night, the night market is still lively, and there are people in front of almost every stall to choose items.

Chen Ya, who had 12,000 in his arms, quickly found a stall specializing in mechanical parts, and with a wave of his hand, he directly bought two brand-new small hydraulic pumps.

That's it, 10,000 gone!

Chen Ya thought very clearly, the materials of the exoskeleton should be gathered as soon as possible, although they cannot be assembled for the time being, they will come in handy sooner or later.

There were still two thousand left, and Chen Ya bought two more alloy steel plates and spent two hundred steel plates.

1800 Wasteland Coins remaining.

I have to say, money is a bastard!

Chen Ya resisted the urge to continue buying, and then began to prepare for tomorrow's main quest.

The first is weapons.

Even if you don't have firearms, not to mention the price, the consumption of ammunition is also very large.

Chen Ya chose a cold weapon, and it must be a type that is easy to carry, but after visiting several weapon stalls in a row, he did not find a suitable weapon.

That is until he finds an alloy boning knife on a stall selling meat products.

However, I saw that the boning knife was silver-colored, the blade was sharp, narrow, and shining, and its appearance was somewhat similar to that of a military thorn, and its length was only more than 30 centimeters.

Chen Ya's eyes lit up, and when the stall owner saw this, he couldn't help but smile and asked:

"Little pot friend, do you want to buy some meat to eat?"

"Okay."

Chen Ya said and took out ten steel hammers, bought a kilogram of high-quality jerky, and asked at the same time:

"Boss, do you sell your boning knife?"

"Boning?"

The stall owner was stunned, and Chen Ya explained with a smile:

"I want to buy a boning knife and learn slaughtering techniques."

"Yes, ambitious!"

Hearing this, the stall owner was a little happy, and then said:

"To be honest, I'm pretty comfortable with this knife, but if you want it, give me fifty steel hammers, and take it."

"Thank you, uncle."

Chen Ya hurriedly took out the money, and after successfully buying the boning knife, he found that the feeling of holding it in his hand was really light.

And the cold light flickering on the blade......

It also means that this is definitely a sharp weapon.

Yes, this weapon is enough!

Chen Ya was very satisfied, and then considering that there were many items on his body, he could only buy a large rucksack and spend twenty steel hammers.

There are 1730 Wasteland Coins left.

Now, in addition to medicines, Chen Ya also needs to buy dust masks and radiation protective clothing.

These two things are a must-buy.

Know that 'radiation' is not the same as 'nuclear radiation'.

Radiation is a phenomenon of electromagnetic energy propagation, and many electrical devices have radiation.

For example, computers, mobile phones, wifi, monitors, hair dryers, etc., the radiation value of these electrical appliances is only 0.1 mSv at most, or even less.

This kind of radiation value is not much harmful to the human body, at most there are computer radiation spots on the face or something.

The really harmful radiation, mainly 'nuclear' radiation.

Nuclear radiation is a stream of microscopic particles emitted by radioactive material.

For example, uranium-235, the material of the atomic bomb, has strong nuclear radiation.

There are three main types of nuclear radiation, namely α, β, and γ.

That is, alpha, beta, gamma.

English Words:

Alpha Ray (Alpha)

Beta Ray (Beta)

Gamma rays (gamma)

Of course, there is a fourth.

Neutron rays, also known as neutron radiation

……

Nuclear radiation is generally these four, and the specific characteristics will not be introduced for the time being (see the related works).

But here's what you need to know......

If the nuclear pollution dust of the first two rays falls on the skin and hair, it can basically be cleaned up, and as long as it does not enter the mouth, nose and respiratory tract, there is not much danger.

Therefore, dust masks are designed to deal with 'alpha' radiation as well as 'beta' radiation.

As for the extremely penetrating 'gamma' radiation......

You need to wear protective clothing, otherwise you can't prevent it at all, because gamma rays are ultra-high-energy electromagnetic waves, the energy is more than 100 times that of X-rays, and it has extremely strong penetration.

Chen Ya spent ten steel hammers to buy a pair of dust masks.

The next step is to choose a radiation suit.

There are about two types of ordinary types of protective clothing, the first of which is:

Radiation protection clothing (aluminum foil)

Feature: Lightweight

Weight: five kg

Defense: 300 mSv

Cost: 500 Wasteland Coins

……

Chen Ya's body has a first-level radiation resistance of 1,000 mSv, and if you wear an aluminum foil protective suit, you can increase its resistance by 300 mSv.

That is to say, below 1300 mSv, there is no need to worry about the body being harmed.

Don't underestimate these 300 millisv, sometimes for a long time, it happens to be a dose of several hundred millisv, which will make people walk into the abyss, and even slow death.

In addition to light protective clothing made of aluminum foil, the second type is heavy-duty.

Radiation protection clothing (lead clothing)

Features: strong protection ability

Weight: thirty kg

Defense: 1000 mSv

Cost: 2000 Wasteland Coins

……

In fact, in the medical profession in previous lives, lead clothing was often used.

Usually, when a heart patient undergoes surgery, because the cardiac interventional equipment will emit X-rays, which will cause harm to the human body, the medical staff in the operating room must wear lead clothing to protect against radiation.

Of course!

Today's lead coat is heavier, weighing sixty pounds.

The protection is also very strong, with the ability to increase radiation resistance by 1000 mSv.

It's a pity that Chen Ya can't look down on it, because the lead clothes are too heavy, if he wears it, it will inevitably affect the play of speed, so he naturally won't choose to buy it.

Besides, he can't afford it now.

After a while, Chen Ya spent 500 steel hammers to buy a silver aluminum foil protective suit, and then put it into a large backpack.

Actually.

In addition to the above two types of protective clothing, there are more advanced ones.

It's just that in terms of price, it's ridiculously high.

Of course, in addition to protective clothing, the body's radiation resistance can also be enhanced through 'chemicals'.

Pharmacy + dust mask + protective clothing

This is the standard equipment for traveling to the wasteland.

Fortunately, in terms of potions, Chen Ya was not short for the time being, and now after buying the necessities, he also found the stall that sold live animals that day.

But I saw that the previous mutant bamboo rat was no longer there.

In its place was a female mutant goat, and the stall owner shouted:

"Freshly milked goat's milk! Twenty pounds of steel! ”

Seeing that there was goat's milk, Chen Ya's eyes lit up, and he immediately thought of jumping, so he took out a hundred pieces and said:

"Boss, come five catties of goat's milk!"

"Okay."

The stall owner smiled, took out the container, squeezed five catties of goat's milk, and handed it to Chen Ya.

I have to say that this stall owner is very good at business.

And the milk production capacity of that mutant goat is definitely more than that of ordinary goats in the previous life, and dozens of catties of goat milk a day are definitely not a problem.

This also made Chen Ya can't help but ask:

"Boss, this mutant goat, are you selling?"

"Not for sale!"

The stall owner replied firmly.

Chen Ya was a little helpless, and after collecting the goat's milk, he couldn't help but look at the eggs on the stall and asked:

"How to sell the eggs of the mutant cocoon bee?"

"One steel hammer."

The stall owner smiled, Chen Ya was speechless, although it was a little expensive, he still took out fifty steel hammers and said:

"Fifty eggs, I'll choose myself."

The stall owner who received the money immediately smiled and said:

"You feel free."

Immediately afterwards, Chen Ya put down his big backpack, and then squatted in front of the stall and began to select insect eggs.

He plans to use these eggs tomorrow to go to the wasteland outside and do a small experiment.

However......

Just as Chen Ya lowered his head to select the eggs, a guest came from behind.

However, the guests glanced at the stall and saw the golden retriever monkey wearing a golden hoop, and their eyes suddenly lit up.

In the next second, the old man looked at the stall owner and asked:

"Boss, do you want to sell monkeys?"

After speaking, he raised his hand and pointed at Chen Ya.

Hearing this, the stall owner was dumbfounded, and was about to open his mouth to explain, but Chen Ya jumped up, glared and scolded:

"Sell your sister, I'm human! Not a monkey! ”

Burst! ~

The stall owner burst out laughing, and the guest was stunned, then he reacted, and immediately laughed:

"Little pot friend, don't be angry, uncle admits his mistake."

Do you recognize that way?

Chen Ya's face was speechless, and then he selected fifty insect eggs and went home directly.

What a mutant was mistaken for a monkey.

It hurt him a lot.
