Chapter 20

The production page was pulled to the bottom, Su Mo thought clicked, and the material list jumped out.

[hunting composite crossbow: wood 0/8, iron 0/8, copper 0/4, nylon 0/2, composite nylon 0/1]

[5 crossbows: 0/2 wood, 0/1 iron]

After unlocking the drawing of the composite crossbow, the supporting crossbow making drawing is self-contained, and Su Mo does not need to obtain it again.

"The iron block is easy to handle."

"Now it's just nylon, composite nylon and copper."

"I don't know if others have nylon in their hands. Copper should be easier to get."

Thinking and greeting Oreo back, sumo walked back to the shelter.

When exploring the game panel, it is easy to ignore the surrounding environment, so when browsing the trading market, sumo will generally do it in the shelter.

When checking the trading items before, Su Mo saw many strange little things.

At this time, a search found the trace of the copper block on the trading panel.

At present, the price of a piece of copper is 100ml water, while nylon is temporarily absent.

"The prices these people are selling are too high"

Su Mo glanced around and suddenly found that there were only two people selling copper pieces. Before he could buy the newly hung copper pieces, they took them away.

These players, like game merchants, hoard resources that are currently in short supply and sit on the ground to raise prices.

"It's better to collect it by yourself, and it's more cost-effective to trade you energy water for materials."

Su Mo pondered for a moment and hung up several groups of trading methods.

[seller: sumo]

[trading product: 50ml Youneng water]

[demand: 1 copper block]

[inventory: 200ml]

...

[trading product: 100ml Youneng water]

[demand: nylon *2]

[inventory: 200ml]

...

[trading product: 200ml Youneng water]

[demand: composite nylon]

[inventory: 200ml of Youneng water]

In the eyes of most people, the acid rain that will come tomorrow is not called disaster, but "supply".

Since the morning, the purchasing power of water has been declining.

Not only the exchange of materials, but also the exchange of equivalent food, are greatly discounted.

Fortunately, the purchasing power of Youneng water is still strong.

The purchased materials can meet the material demand for manufacturing hunting composite crossbow.

Less than half a minute after the replacement of copper block was put up, four units were traded.

"Boss, where did you dig the Youneng water? Don't worry. After we dig it, shall we divide it by 19?"

"Su Shen, I still have copper pieces. Please take mine. I haven't drunk water for a day."

"Sir, I have nylon, but the price is not enough, and it will rise!"

“....”

Private messages came one after another.

This is the nth time that sumo has sold you Neng water, so almost everyone guessed that he has a fixed gold mine with constant water sources.

Most people buy Youneng water back, but it's not all for thirst quenching.

Basically, they are stored as strategic medical supplies. In case of injury, they may be able to hang a life by relying on the hidden energy water.

World channel, regional channel, and a large number of people have been opened the chatterbox, around the two kinds of nylon that sumo needs to discuss one after another.

After just testing, sumo has learned that nylon is not a shortage, but that some people are unwilling to sell it with the intention of raising the price.

Looking at more and more private messages, Su Mo set the keywords of composite nylon and ignored them.

We haven't encountered a fatal threat at present, so we don't need a composite bow for the time being. Maybe it will be delayed for a while, and some people may sell it at a low price in the evening.

After ranking according to the price, sumo received 50 units of stone again, making up for the loss of the previous canal construction.

After slowly taking out all the construction resources and stacking them in the shelter, sumo was in a mood of excitement.

Living in a wood shelter is good in the early stage. With the passage of time, wood will always lose its rigidity one day, which is really not safe.

Now we have enough conditions to upgrade the stone shelter. Su Mo doesn't have ink and starts to upgrade manually.

The first thing to upgrade is the gate of the shelter, which is also the first security line in the waste soil.

[shelter gate]

Effect: slightly anti-theft, slightly anti radiation

Upgrade direction 1: increase the thickness of the wooden door, increase the firmness of the wood, and slightly fireproof and waterproof (10)

Upgrade direction 2: change the material, upgrade the wooden door to the stone door, and greatly increase the durability and other properties (5)

Evaluation: you don't want to live in the afterlife by relying on a wooden door, do you?

Click upgrade direction 2. The stones on the ground are scanned with green light, and ten units of stones are melted into stone water and attached to the wooden door.

After a short wait, the original wooden door disappeared and replaced by a simple stone door.

Push open the stone door bolt, pull the wooden stone door handle, and slowly push open the stone door, Su Mo was surprised again.

The stone gate is 20cm thick. Even bullets with such a thickness are difficult to shoot through. As long as he closes the door inside, no matter how many people outside can't break in.

Of course, if these people don't have explosives

The workmanship outside the stone gate is very rough, and the system also notices the concealment in the upgrade. Although it still looks out of place in the wilderness, at least ordinary creatures will only regard it as a rough rock.

After closing the door and returning to the base, sumo began to upgrade one by one.

Every time the green light is scanned, the original wooden floor will undergo earth shaking changes and become a light gray stone floor.

After upgrading the foundation, sumo began to upgrade the load-bearing and ceiling again.

With the discoloration of the last piece of wood, the shelter is completely new.

The first is the internal environment.

There was no longer a damp feeling, and the dirt on the board also disappeared after days of activities.

At this time, the ground is tidy, and the whole body is composed of light gray. Because the grinding is extremely smooth and flat, at first glance, it is a little like sticking gray tiles.

At this time, some potholes have been filled under the system upgrade.

The color of the stone on the wall is dark brown with a little simplicity, and a trace of stone grain is pulled up from time to time, making the shelter not so boring.

The ceiling above the head adopts the same color as the wall, which makes it more integrated.

"Good"

Su Mo looked around and opened the whole picture of the shelter in the game panel.

[personal shelter]

Description: the whole body is made of stone, which is extremely strong, has good safety, and has a unique effect in isolating moisture and keeping warm.

Space: 100 ㎡ (floor height 4.2m)

Integrity: 100%

Facilities: iron stove, bed, large vegetable culture medium, Youneng well water extractor, dining table

Introduction: everyone has to pay for their youth, only you have to build a house for your youth.

"This is the greatness of human civilization!"

Su Mo felt his palm and sighed. The biggest advantage of the refuge made of stone is nothing else, just two words-

Safe!

The security that everyone desperately sought in the end of the world, now sumo took only four days to build.

Walking around, feeling here, looking there, looking at the new shelter, Su Mo couldn't help but feel happy.

"Unfortunately, if only there were electricity, where is the reinforced concrete comfortable to live in this stone house? When the time comes, install a bathroom, no, install a bathtub, watch a movie, drink red wine..."

Looking at the ceiling, sumo sat on the stairs, dreaming.

Coming to this world, the closer the environment in the shelter is to the earth, the more complicated Su Mo's mood becomes.

From nothing, from the stone age to the electrical age, human beings have used it for more than 5000 years.

And a person's life span is only a few decades at most. Is there really a day to restore power at the precarious end?

He clenched his fist, and Sumo threw the gloom behind him.

Now is not the time to sigh. He can't even walk out of the nearby wilderness for three kilometers. What about the future!

After counting the materials, the reserve of Youneng water has recovered to about 2.5L again, not counting 400ml sold on the trading market.

Leaving 1L of water for standby, sumo began the last wave of cargo sweeping before the disaster.
