My Post-Apocalyptic Shelter Levels Up Infinitely!

　　 "Do you want to bind?"

　　 When the unfamiliar mechanical sound sounded for the second time, Somo reacted and quickly responded:

"Yes"

　　 "In binding... 0.1% progress, 0.2% progress"

　　 A line of illusory green scanning rays spread out from under Somo's feet and spread far away.

　　 When the limit was reached, the light returned again, and the progress increased by 0.1%.

　　 While binding, Somo opened the wooden door and looked in.

　　 Behind the wooden door is a ladder made of mud.

　　 down the stairs, waited until the count of fifteen in his heart, suddenly suddenly became clear.

　　 With the help of the faint sunlight coming from the entrance of the cave, Somo could barely see the structure inside.

　　 The ground and roof made of wooden planks form a stable foundation to ensure that this huge pit does not collapse in the ground.

　　 "Right bet!"

　　 Sumo's face was overjoyed.

　　Choosing the ground is certainly beneficial, and it can get some convenience in the early stage of development.

　　 But he has never forgotten one thing. With the tools to make pages, it is not difficult to build a house on the ground.

　　 But if you want to build a shelter underground, you must not only rely on tools, but also have enough architectural knowledge to ensure the stability of the underground structure.

　　 Otherwise, digging randomly, I am afraid that I will die at night without knowing how to die.

　　 Seeing the binding progress bar of the apocalyptic survival system is still slowly rising, Sumo simply sat on the stairs, saving energy while opening the chat panel.

　　 Maybe someone else has this so-called end-time survival system?

　　 first watched the world channel for a while, then opened the regional channel and watched it for a while.

　　 No one mentioned this.

　　 "It seems that I alone have two systems?"

　　 Somo came to a conclusion.

　　 At this time, most of the people who spoke actively on the World Channel and the Regional Channel chose the refuge above the ground, and only a few chose the underground.

　　 But the one who chose the underground was just complaining about the misfortune of the underground, and then began to communicate and search for supplies.

　　 There is no reference, and I don’t know what it is, so Suma has to wait.

　　 Fortunately, the improvement of the progress bar was very stable. After more than ten minutes, the green light finally stopped scanning. After returning to Somo's body for the last time, a crisp prompt sounded:

　　 [Doomsday Survival System bind successfully]

　　【First binding reward: 100 survival points】

　　 [Scan the host's survival environment, and the survival point is being evaluated, and today I get 5 survival points. 】

　　 [Final settlement, you got a total of survival points today: 105 points! 】

　　 [Remaining survival points: 105 points! 】

　　 As the prompt sounded, a large fragment of memory was transmitted.

　　 Originally, the end-time survival system was a product that he could bind to the world before, but unfortunately, the information was blocked at that time, and the country did not notify all people to enter the shelter until the day before the disaster.

　　 Naturally, he didn't have time to dig a personal refuge, thus missing the system binding.

　　 After coming to this world, if the survival game panel is a game panel, everyone has it and everyone can use it, then the doomsday survival system is a modifier, only Suma owns.

　　According to the apocalyptic survival system, every day of survival, you can get a certain survival point.

　　 Survival points are similar to points in the game and cannot be exchanged for items directly.

　　Its function is similar to the item upgrade function in the game, but the scope of upgrades is more comprehensive.

　　 As he learned more and more, Somo resisted the excitement in his heart and fixed his eyes on the rudimentary underground survival base:

　　【Personal Refuge】

　　 Owner: Su Mo

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

　　 Completeness: 100%

　　Facilities: None

　　 Introduction: An extremely simple refuge, without any survival facilities, at best it can be regarded as a small tomb in the apocalypse.

　　 Looking at the introduction on the panel, Somo moved inwardly and turned to look at the wooden door, the only item in the refuge.

　　【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 iron door, greatly increase durability and other attributes (30)

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

　　 After observing for a while, Somo reluctantly sorted out the use of the doomsday survival system.

　　 In addition to relying solely on survival points to upgrade the system, users can also provide materials, which greatly reduces the survival points required for the upgrade program.

　　 For example, if you upgrade a wooden door to an iron door, if he can provide 3 units of iron and 1 unit of wood, the survival point required for the upgrade will drop to 5.

　　The survival point can be used as any substance, but it is definitely not as good as the original substance in terms of conversion efficiency.

　　 So as long as enough similar substances are provided, and the survival point plays a role of transformation and assimilation, consumption can be greatly reduced.

　　 After understanding these circumstances, the pressure of survival that had been pressing on Somo's heart finally became much smaller.

　　 "I want to create a strong enough refuge before my parents and sister launch"

　　 "Before this, solve the material problem first"

　　 clenched his fists secretly, and walked out of the refuge along the steps.

　　 Drinking water and food are the first issues to be concerned about.

　　 Fortunately, now that there is a survival system, a general development route has appeared in Somo's mind.

　　 first came to a small tree, used the body's own weight to break the branch and put it in the inventory, and then a reminder came out.

　　【Timber+1】

　　 Then Somo looked for solid stones on the ground and put stones of different sizes in his inventory. Not long after, another prompt sound came out:

　　【Stone +1】

　　 "Sure enough, it has become gamified, but this is also good, at least my stamina will not be much weaker than others in the early stage"

　　 is no longer tangled in reality and has moved so close to gamification.

　　 Next, try the manufacturing function first!

　　"Open the manufacturing panel"

　　The interface changes.

　　【Stone Axe (Ordinary): Wood 1/1, Stone 1/1】

　　 Material is satisfied.

　　 Select the stone axe.

　　Confirm the build!

　　 [Record]: Wood-1, Stone-1

　　 [Record]: The stone axe (normal) was successfully created.

　　 Sumo had an extra stone axe about forearm length in his hand.

　　The axe body is rough wood, which has good friction and can make people grasp the axe body tightly.

The 　　 axe is a very smooth and sharp wedge.

　　 [Stone Axe (Ordinary)]: A brand new axe without wear and tear. The current length is 60cm. With it, your wood collection will be much easier.

　　"Not bad yet"

　　 Somo made a few gestures.

　　 The sharpness of the stone axe certainly cannot be compared with that of the iron axe, but with it, cutting trees is a lot easier.

　　If you want to be rich, you must first touch the tree.

　　 was thirst, and under the scorching sun, after cutting 15 units of wood and 4 units of plant fiber, Somo returned to the underground shelter along the original road.

　　 The shady underground slightly calmed the heat of the body, but the protest from his throat made Somo feel more anxious in his heart. UU reading www. uukanshu.com

　　 People can last 7 days without eating, and 3 days without drinking water.

　　 Especially after heavy labor, I am afraid that I will die of thirst on this wasteland if I don’t drink water for two days.

　　 "First try to build a simple water intake device with materials to see if the system can be upgraded"

　　 After resting for a while to recover some strength, Somo came to the place where he had sheltered from all the sunlight, and began to remove the floor with the stone axe in his hand.

　　 did not touch the surrounding floor. After carefully removing a piece, Somo took out the wood.

　　 first made a wooden barrel with four units of wood.

　　 then used one unit of wood to make a stick, two units of wood to make a wooden shovel, and finally two units of plant fiber to make a hemp rope.

　　 A whole set of guys are ready.

　　Sumo picked up the wooden shovel and dug up the hole dug in the ground.

　　 is easier than imagined.

　　With tools, the wooden shovel can bring up a lot of dirt every time it falls.

　　 After digging a deep hole enough to hold the barrel, Somo stopped the work in his hand and began to assemble the tools he had built before.

　　 The wooden barrel is put down, the wooden stick is hung between the two floors, and the wooden barrel and the wooden stick are connected with hemp rope.

　　 Afterwards, the mind was concentrated, and the prompt of the survival system popped up.

　　【Well water extractor? ? ? 】

　　Current efficiency: 0ml/day

　　 Upgrade direction 1: Upgrade the barrel material, increase the barrel volume, increase the sealing function, so that the drinking water preservation time is greatly extended, and the upgrade consumes 20 survival points.

　　 Upgrade direction 2: Expand deep wells, strengthen water extraction efficiency, upgrade costs 130 survival points.

　　 Evaluation: A pit, a bucket, the well water is made up by your brain?
