After a brief rest for a few minutes, Lu Yan removed the cut-down fir branches, retaining only the thickest trunk parts, and then cutting the trunk into several parts according to three meters.

This is a physical job. If Lu Yan hadn't been strong, he might have been exhausted long ago.

After about three hours, a bunch of straight and clean wooden pillars appeared in front of Lu Yan. He wiped the sweat beads on his forehead and nodded with satisfaction.

【Get 3m wooden pillar x8】!

【Get fresh branches x182】!

【Get air-dried dead wood 50kg】!

The advantage of gamification in the doomsday world is that the collected materials can be collected into a virtual backpack lattice, without physical transport, and also saves the storage process.

However, more and more materials were collected in the later stage, and the grid in the virtual backpack would definitely not be enough. At that time, you need to build your own [warehouse].

On the way back to the safe house, Lu Yan had only one feeling.

That's thirst.

Very, very thirsty.

The temperature in the wilderness is very high during the day, which can reach more than forty degrees. Coupled with the vigorous exercise when cutting trees just now, Lu Yan had already sweated heavily and was almost dehydrated.

The consequences of dehydration are very serious. In mild cases, the disorder is unconscious and faints, and in severe cases, the organ failure is directed...

In the dangerous wilderness, whether it is fainting or organ failure, one result cannot be escaped...death!

Although he is in "Doomsday Survival Game", Lu Yan does not think that he can really be resurrected infinitely like the characters in the game. He is very sure that if he dies in this game, he is real death.

During the process of cutting down trees just now, Lu Yan noticed that the physical feeling of "tired, thirsty, and grinding" was extremely real. Except for some areas [dataization], most of the rules are the same as the real world.

This is a real doomsday world under the name of the game!

...

Walking into the safe house, the sudden darkness made Lu Yan's eyes difficult to adapt. After a long time, he saw everything in front of him with the help of the faint light coming through the crack of the door.

"This kind of light transmission cannot meet the needs of daily life at all." Lu Yan muttered.

This is the disadvantage of underground safety houses, which have poor ventilation and light transmission, and the drainage system is basically equal to zero.

Lu Yan felt like a mouse now, hiding in a dark cave.

"But in the early stage... safety first! Comfort is something like that, you have to be based on surviving before you can be qualified to consider it." Lu Yan thought about it and felt relieved. At least in terms of safety, the underground safe house had to be thrown a lot on the ground.

Taking out the 8 wooden pillars in the backpack and opening the [upgrade] interface of the Doomsday Survival System. Lu Yan looked at the safe house, and two lines of prompts immediately appeared in front of him.

【Thick fir columns can be used to strengthen the load bearing of the safe house and consume 5 survival points】

【Thick fir columns can be split into short wooden pickets, which are used to set up a circle of grilles around the safe house, consuming 5 survival points】

Grille?

This kind of thing can only be used to resist wild beasts, right?

Lu Yan thought about it and gave up this choice. He chose the underground safe house because it could prevent wild beasts from attacking. Adding a circle of grilles seemed a bit redundant. In the early stage of shortage of resources, their role must be maximized.

[Reinforced safe house load bearing]!

Soon, with the green light flashing, 8 wooden piles evenly appeared in eight directions of the safety house, firmly supporting the beams of the roof!

After 8 additional load-bearing columns, the safety house that originally looked shaky suddenly became much more stable.

Lu Yan breathed a sigh of relief.

At least now, there is no need to worry about the roof falling down when you go to bed at night.

"Tons tons!"

After a few big mouthfuls of water, Lu Yan felt that the fatigue and heat on his body were wiped out. He held a knife in his hand and took out the branches of the fir tree from his backpack. He slowly peeled off the outer bark. After being knocked and rubbed, he formed thick fibers like hemp ropes.

He wanted to weave a hammock with these barks.

The wilderness is full of dangers. Do you know if a poisonous snake will crawl into a safe house in the middle of the night. It is too dangerous to sleep on the ground.

Making a hammock can not only improve comfort, but also avoid harassment from insects, rats and snakes.

This work is effortless, but it is very energy-consuming.

As for the system's [manufacturing] classification, although there are options for [hammock], the materials required are nylon ropes, springs, hooks, etc. The products of the system are all regular and mass-produced modern civilization products, such as bark hammocks and turf aprons, which are similar to primitive society, and are not within the scope of the system's manufacturing.

It was not until sunset that Lu Yan completed the production of this hammock. Although it looked a bit ugly, it was very sturdy.

He tied the two ends of the hammock to the two load-bearing pillars of the safe house, and tried to lie on it to stretch his hands and feet, and an uncontrollable sense of comfort and accomplishment surged into his heart.

The most basic safety problem has been solved, so we must consider food and future developments...

Lu Yan thought about it and opened the game's trading interface.

In just one afternoon, the originally empty trading interface was filled with dense commodities.

【Seller: Han Siyuan】

【Sold Items: Homemade Stone Axe】

【Article Required: 500 ml of pure water】

[Note: Don't look at this thing as ugly as it looks, it can save your life at critical moments. It took me an afternoon to make it. It's OK to cut off the wood as thick as a baby's arm!]

...

【Seller: Wu Xionghai】

【Sold items: 2kg earth and salt】

【Required items: 1 liter of pure water】

[Note: Are there any geniuses in the blasting world? Do you want to dominate the wilderness? First enter the firearm age from the Stone Age? One nitrate, two sulfonium, three charcoal, and some white sugar. Big Ivan! When others are still using stone axes, you can smash people with grenades!]

...

[Seller: Duan Wude]

[Sold Items: 452 ml of liquid that can quench thirst and cure dehydration syndrome]

【Required items: food, weapons】

[Sales Status: The transaction has been completed three minutes ago]

[Buyer's message: I drafted the uncle, I thought it was ice black tea, but it turned out to be urine! No wonder I have zero or even a whole amount! Duan Wude, don't let me meet you in the wilderness. When you meet your hair, you must pull it all over and slap you in the face!]

Lu Yan looked at the transaction information and touched his chin, feeling that the trading system was interesting.

Sellers can edit the information of the items sold by themselves, and as long as the functions described are the same as those described, they can be put on the shelves.

In this transaction, all the functions described by the seller are in line with the same.

In extreme water deficiency, urine can indeed quench thirst and help life, but not at the critical moment of life and death, who is willing to drink urine?

Lu Yan didn't want to accuse the seller of being immoral. He could only say that he was facing a survival crisis in the wilderness, and the seller was just more cunning than others.

After browsing a large number of products, Lu Yan's eyes suddenly lit up.

【Seller: Kadylov】

【Sold items: 10kg wild wolf meat】

【Required items: 10 liters of pure water】

【Note: The wild wolf I just hunted has absolutely fresh meat】

Damn...

Lu Yan not only sighed, is this player so powerful? When most people were still picking up stones and picking wood, he had already killed a wild wolf alone?

But soon when Lu Yan saw the seller's simple personal information, he felt relieved.

Ahamad Kadylov, male, Chechin.

"It's a fierce man from the fighting nation..." Lu Yan touched his chin.

Regarding the Cheqin people, Lu Yan had heard of their rumors a long time ago. They were born militants and contained fierce genes in their bones.

How cruel are these people? Let's put it this way... If the Cheqin people pass through the war, the eggs will be shaken and yellow, the earthworms will be cut up with a knife, the ants will be scalded with water, and the passing dogs will be beaten with two big mouths!

If summer comes, you will be beaten by the air conditioner remote control, and you will be brushed with a steel wool ball for the non-stick pan!

Although the rumors are quite ridiculous, they are enough to show their fierceness.

Lu Yan now needs food in urgent need, and Lu Xiaoyu's disease requires long-term consumption of meat, so without any thought, Lu Yan immediately chatted with the other party.

[Lu Yan: Friend, I want your wolf meat, but can the price be lowered?]

In the trading field, bargaining is a necessary skill, especially when you first enter the wilderness, no one will foolishly buy according to the other party’s price.

【Kadilov: How much can you pay?】

[Lu Yan: Your price is too high, I can only pay 500 ml!]

Lu Yan used the Dragon Slaying Sword technique and cut the price to his heel with one knife.

At this time, somewhere in the wilderness, a burly and fierce bearded man stared at his eyes, stepped on a wild wolf whose neck was twisted, his tongue kept licking his cracked lips, and replied in the private chat interface with a little irritable attitude.

[Kadilov: Are you kidding me? I can drop to 5 liters at most!]
