MTL - My Post-Apocalyptic Shelter Levels Up Infinitely!-Chapter 20 upgrade! Stone refuge!

　　 The production page was pulled to the bottom, Sumo clicked on it, and the material list popped up.

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

　　 [5 matching crossbow arrows: wood 0/2, iron block 0/1]

　　 After unlocking the blueprint of the composite crossbow, the blueprint for making the matching crossbow bolt comes with it, so there is no need for Somo to get it again.

　　 "Iron block is easy to handle"

　　 "Nylon, compound nylon, and copper are missing now"

　　 "I don't know if others have nylon, the copper block should be relatively easy to get."

　　While thinking, he greeted Oreo to come back, and Sumo walked back to the refuge.

　　 When exploring the game panel, it is easy to ignore the surrounding environment, so when browsing the trading market, Suma usually conducts it in the refuge.

　　 When checking the trading items before, Somo had seen many weird little things.

　　 A search at this time, and indeed found traces of the copper block on the trading panel.

　　 The current price of a piece of copper is 100ml of water, while nylon is temporarily missing.

　　 "The prices these people sell are too high"

　　 Sumo browsed around, and suddenly found that there were only two people who were selling copper blocks. Before he could buy the new copper blocks, he was taken away by these two people.

　　 These players, who are similar to game merchants, hoard resources that are still in short supply and raise prices on the ground.

　　 "It's better to collect it yourself, and it's more cost-effective to change the material with the nether energy water"

　　 Sumo pondered for a moment, and hung up several sets of trading methods.

　　【Seller: Su Mo】

　　 [Trade: 50ml Youneng Water]

　　[Requirement: 1 copper block]

　　[Inventory: 200ml]

　　...

　　 [Trade: 100ml Youneng Water]

　　[Requirement: Nylon*2]

　　[Inventory: 200ml]

　　...

　　 [Trade: 200ml Youneng Water]

　　 [demand: composite nylon]

　　 [Stock: 200ml Youneng Water]

　　 The acid rain that is coming tomorrow is not a disaster in the eyes of most people, it is called "supply."

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

　　 is not only the exchange of materials, but also the exchange of the same food, which is greatly discounted.

　　 But fortunately, the purchasing power of You Neng Shui is still strong.

　　 These materials purchased can just make up the material requirements for the manufacture of hunting composite crossbows.

　　 The replacement of the copper block had just been hung up in less than half a minute, and the transaction for four units was completed.

　　 "Big brother, where did You Neng Shui dug it? Don't worry, after dug it, we will divide it into 19, okay?"

　　 "Su Shen, I still have copper nuggets, please accept mine, I haven't drunk water for a day"

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

　　 "..."

　　 private messages followed one after another.

　　 This is the Nth time that Somo has sold nether energy water, so almost everyone guessed that he has a fixed gold mine with a steady flow of water.

　　 Most people buy the Nether Energy Water back, and it is not all for quenching their thirst.

　　 Basically, they are stored as strategic medical supplies. In case of any injury, they may be able to hang their lives by relying on the nether energy water.

　　World channel, regional channel, a large number of people were opened up, discussing the two kinds of nylon that Suma needed.

　　 After the trial just now, Somo has learned that nylon is not in short supply, but some people are unwilling to sell it because of the price increase.

　　 Seeing more and more private messages, Somo set the keyword of compound nylon and ignored it.

　　 I haven't encountered a fatal threat in front of me. I don't need a compound bow for the time being. Maybe some people will sell it at a low price at night.

　　 After sorting by price, Somo received 50 units of stone again to make up for the loss of the previous canal repair.

　　 Slowly took out all the construction resources and piled them up in the refuge, Sumo was in agitated mood.

　　 Living in a wooden refuge, the early stage was okay. With the passage of time, the rigidity of the wood will always be lost one day, which is really not safe.

　　 Now that he has enough conditions to upgrade the stone refuge, Somo doesn't have any ink marks, and starts to upgrade manually.

　　 The first upgrade was the door of the refuge, which was also the first line of defense in the wasteland.

　　【Gate of Refuge】

　　 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 fire and waterproof (10)

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

　　 Evaluation: You don’t want to live in the end times by a wooden door, do you?

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

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

　　 pushed open the stone door bolt, pulled the wooden stone door handle, and slowly opened the stone door, Sumo was surprised again.

　　 The thickness of the stone gate is 20cm wide. Even if it is a bullet, it is difficult to shoot through. As long as he closes the door inside, no amount of people can break in.

　　 Of course, the premise is that these people don't have explosives...

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

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

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

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

　　 Accompanied by the last piece of wood discoloration, the shelter has a new look.

　　 First of all, the internal environment.

　　 no longer has a feeling of dampness, and the dirt on the wooden board has also disappeared after the day-to-day activities.

　　 At this time, the ground is neat and tidy, and the whole body is made of light gray. Because the polished surface is extremely smooth and flat, it looks a bit like gray tiles at first glance.

　　 Some of the original potholes were filled under the system upgrade at this time.

　　 The color of the stone on the wall is a quaint dark brown, with a trace of stone drawn up from time to time, making the shelter not so dull.

　　The ceiling above the head is the same color as the wall, giving it a sense of unity.

"good"

　　 Sumor looked inside and out, then opened the whole view of the shelter in the game panel.

　　【Personal Refuge】

　　 Description: The whole body is made of stone refuge, strong and unusual, with good safety, it has a unique effect in isolating moisture and keeping warm.

　　Space: 100㎡ (the height of the floor is 4.2m)

　　 Completeness: 100%

　　Facilities: iron stove, bed for UU reading www.uukanshu.com, large vegetable culture medium, water extractor for Nuneng well, dining table...

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

　　 "This is the greatness of human civilization!"

　　 Su Mo stroked his palm and sighed, the biggest benefit of the refuge made of stones is nothing but two words-

Safety!

　　 The security that everyone is struggling to pursue in the last days, now Suma only took four days to build it.

　　 Walking up and down, feeling here and there, looking at the newly refurbished shelter, Suma couldn't help but feel happy.

　　 "Unfortunately, if there is electricity, it will be fine. This stone house is not comfortable with reinforced concrete. At that time, I will install a bathroom. No way, install a bathtub, watch a movie, drink wine..."

　　 Looking at the ceiling, Somo sat on the stairs, thinking about it.

　　 Coming into this world, every time the environment in the refuge is closer to the earth, Somo's mood becomes more complicated.

　　 From scratch, from the Stone Age to the electrical age, mankind has used it for more than a thousand years.

　　 And a person's life span is only a few decades at most. In the precarious end, is there really a day when electricity is restored?

　　 clenched his fist, Somo threw the gloom behind his head.

　　 It's not the time to sigh. In the nearby wilderness, he hasn't even been able to get out for three kilometers. How can he talk about the future!

　　 I checked the supplies. At this time, the reserve of Youneng Water was not counted as the 400ml that was listed on the trading market, and it had been restored to about 2.5L again.

　　 1L of water was left as a spare, and Somo started the last wave of sweeping goods before the disaster.

　　 (ps: Is anyone watching...it’s so cold!)
