Shelter, Hope for Upgrade!

"Bind?"

When the unfamiliar mechanical voice sounded for the second time, Su Mo reacted and quickly responded, "Yes."

"Binding in progress, 0.1%, 0.2%..."

A series of illusory green scanning lights spread out from under Su Mo's feet, extending into the distance.

When it reached its limit, the light returned, and the progress increased by 0.1%.

While it was binding, Su Mo opened the wooden door and looked inside.

Behind the wooden door were steps made of earth.

Following the steps down, after silently counting to fifteen in his mind, his eyes suddenly opened up.

With the help of the faint sunlight coming from the entrance, Su Mo could barely make out the structure inside.

The ground and roof, laid with wooden planks, formed a stable foundation, ensuring that the huge pit underground would not collapse.

"A good bet!"

Su Mo's face showed joy.

Choosing the ground certainly had its advantages, allowing for some convenience in the early stages of development.

However, he had not forgotten one thing: with the tools from the crafting interface, building a house on the ground was not too difficult.

But building a shelter underground required not only tools but also sufficient architectural knowledge to ensure the stability of the underground structure.

Otherwise, digging around haphazardly might lead to a collapse at night, and you wouldn't even know how you died.

Seeing that the binding progress bar of the Doomsday Survival System was still rising slowly, Su Mo simply sat on the stairs, conserving his strength while opening the chat panel.

Perhaps others also had this so-called Doomsday Survival System?

He observed the world channel for a while, then opened the regional channel to take a look.

No one mentioned it.

"It seems I'm the only one with two systems?"

Su Mo concluded.

At this time, most of the people actively speaking in the world and regional channels had chosen ground shelters, with only a few choosing underground.

However, those who chose underground only complained about the misery of being underground before starting to communicate and search for supplies.

Without any reference or knowing what this thing was, Su Mo had no choice but to continue waiting.

Fortunately, the progress bar was increasing very steadily. After more than ten minutes, the green light finally stopped scanning, and after returning to Su Mo's body for the last time, a crisp notification sounded:

[Doomsday Survival System Binding Successful]

[First Binding Reward: 100 Survival Points]

[Scanning Host's Survival Environment, Survival Points being evaluated, 5 Survival Points obtained today.]

[Final Settlement, you have obtained a total of Survival Points today: 105 points!]

[Remaining Survival Points: 105 points!]

As the notification sounded, a large chunk of fragmented memories was transmitted.

Originally, the Doomsday Survival System was a product he could have bound on Earth before, but unfortunately, his personal power was limited at that time, and Su Mo had to enter the official shelter to hide.

Naturally, he didn't have time to excavate a Personal Shelter, thus missing the system binding.

After coming to this world, if the survival game panel was a game panel that everyone had and could use, then the Doomsday Survival System was a cheat, only Su Mo himself possessed it.

According to the Doomsday Survival System, he could obtain a certain number of Survival Points for every day he survived.

Survival Points were similar to points in a game and could not be directly exchanged for items.

Their function was similar to the item upgrade function in a game, but the scope of what could be upgraded was more comprehensive.

As he learned more and more, Su Mo suppressed the excitement in his heart and fixed his eyes on the simple underground survival base:

[Personal Shelter]

Owner: Su Mo

Space: 100㎡ (Height: 4.2m)

Integrity: 100%

Facilities: None

Description: An extremely simple shelter, without any survival facilities, at most a small tomb in the doomsday.

Looking at the introduction on the panel, Su Mo's heart stirred, and he turned his head to look at the only item in the shelter, the wooden Shelter Door.

[Shelter Door]

Effect: Slightly anti-theft, slightly anti-radiation

Upgrade direction 1: Increase the thickness of the wooden door, increase the solid properties of the wood, slightly fireproof and waterproof (10 Survival Points)

Upgrade direction 2: Change the material, upgrade the wooden door to a stone door, greatly increase durability and other attributes (60 Survival Points)

Evaluation: You wouldn't want to live in the apocalypse relying on a wooden door, would you?

After observing for a while, Su Mo barely managed to sort out the usage ideas of the Doomsday Survival System.

In addition to purely relying on Survival Points to upgrade, the system can also allow users to provide materials, which greatly reduces the Survival Points required for the upgrade plan.

For example, to upgrade the wooden door to a stone door, if he can provide 10 units of stone and 2 units of wood, the Survival Points required for the upgrade will be reduced to 5 points.

Survival Points can be used as any substance, but the conversion efficiency is definitely not as good as the original substance.

Therefore, as long as enough similar substances are provided, and the Survival Points play a role in conversion and assimilation, the consumption can be greatly reduced.

After understanding these situations, the survival pressure that had been weighing on Su Mo's heart was finally relieved a lot.

"I want to create a strong enough Personal Shelter before my parents and sister are dropped in."

"Before that, solve the material problem first."

Silently clenching his fist, Su Mo walked out of the shelter along the steps.

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

Fortunately, now that he has the Doomsday Survival System, a general development route has already appeared in Su Mo's mind.

First, he came to a small tree, used his own weight to break off a branch, and put it into the inventory. Then, a prompt came out.

[Wood +1]

Then Su Mo looked for solid stones on the ground and stored stones of different sizes in the inventory. Before long, another prompt sounded:

[Stone +1]

"It really has become game-like, but this is a good thing, at least my physical strength won't be much weaker than others in the early stages."

He no longer dwelled on the fact that reality had become so close to being game-like.

Next, try the crafting function first! "Open the crafting panel."

The interface changed.

[Stone Axe (Common): Wood 1/1, Stone 1/1]

Materials met.

Selected Stone Axe.

Confirm crafting!

[Record]: Wood -1, Stone -1
[Record]: Stone Axe (Common) successfully crafted.

A Stone Axe about the length of his forearm appeared in Su Mo's hand.

The axe handle was made of rough wood, with good friction to allow people to grip it tightly.

The axe head was a wedge shape that had been polished extremely smooth and sharp.

[Stone Axe (Common)]: A brand new, unworn axe, currently 60cm long. With it, your wood collection will be much easier.

"Not bad."

Su Mo gestured a few times.

The sharpness of the Stone Axe certainly couldn't compare to that of an iron axe, but with it, chopping trees was much easier.

If you want to get rich, start chopping trees.

Enduring his thirst, Su Mo chopped down 15 units of wood and 4 units of plant fiber under the scorching sun before returning to the underground shelter along the same route.

The coolness of the underground slightly calmed the heat in his body, but the protest coming from his throat made Su Mo feel even more anxious.

A person can last 7 days without food, but only 3 days without water.

Especially after strenuous labor, he would probably die of thirst in this wilderness if he didn't drink water for two days.

"I have to quickly find a way to make a water collection tool!"

"First, try using the materials to make a simple water collection device and see if the Doomsday Survival System can upgrade it."

After resting for a while to recover some strength, Su Mo came to a place in the Personal Shelter with sunlight and began to use the Stone Axe in his hand to dismantle the floor.

Without touching the surrounding floor, he carefully removed a piece and took out the wood.

First, he used four units of wood to make a wooden bucket.

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

A complete set of tools was prepared.

Su Mo picked up the wooden shovel and began to dig in the hole he had made in the ground.

It was easier than expected.

With tools, the wooden shovel could bring up a lot of soil each time it fell.

After digging a deep pit large enough to hold the wooden bucket, Su Mo stopped his work and began to assemble the tools he had made earlier.

He put the wooden bucket down, hung the wooden stick between the two floorboards, and connected the wooden bucket and the wooden stick with the hemp rope.

Then, concentrating his mind, the Doomsday Survival System's prompt popped up.

[Well Water Extractor???]

Current efficiency: 0ml/day

Upgrade direction 1: Upgrade the material of the wooden bucket, increase the volume of the wooden bucket, and add a sealing function to greatly extend the freshness of drinking water. The upgrade costs 20 Survival Points.

Upgrade direction 2: Deepen the well pit and increase water extraction efficiency. The upgrade costs 130 Survival Points.

Evaluation: A pit, a bucket, is the well water imagined by your brain? The newbie is writing a book for the first time, please give the readers some recommendation votes, thank you!
