"System, upgrade the shelter door!"

[Extremely simple wooden baffle]

Material: steel frame, nailed on wooden board.

Upgradeable directions: concrete wall stack (0), steel gate (460), gravel wall stack (120), complete wooden door (0)...

His steel reserves are far from enough to upgrade the steel gate. Zhang Hao clicked on the entry for concrete wall stacks.

【Concrete Wall Stack】

The two-meter-thick reinforced concrete is extremely strong and is the first barrier of the shelter!

(Note: An explosion-proof iron door with a thickness of 50mm is left below for entry and exit.)

Material requirements: 120 tons of concrete and 10 tons of steel.

What are you waiting for?

What a fuck!

"Upgrade the concrete wall stack!!"

‘Ding, the upgrade begins! ’

With a soft sound of the system, an incredible scene happened!

The light at the door of the shelter began to distort!

In the next moment, the simple baffle door turned into a thick concrete wall!

Great!

No matter how many times I have seen this kind of scene, it still makes people happy!

"System! Upgrade all walls in the shelter to concrete walls!"

‘Ding, the upgrade begins! ’

At this time, the wooden baffles used to separate the rooms finally retreated and turned into a thick concrete wall!

Living area, storage area, industrial area, and production area are separated!

"Initialize all room systems!" Zhang Hao methodically operated on the shelter panel.

"Rebirth sets the living area!"

"Reset the reserve area!"

"[Food Storage Area], [Low Temperature Small Medicine Storage Room], [Luxury Warehouse]..."

"Reset the workplace!"

"OK, done!" After an operation, all the room systems were re-planned.

"Use one-click sorting service!"

"Are you sure to use one-key sorting? Note that each shelter can only be used once!"

"confirm!"

With his order, the entire shelter was distorted. This distortion only lasted for a moment. The next moment, everything returned to its original state, as if nothing happened!

"Are you done?"

He entered the room to check, and all the materials that had accumulated here disappeared without a trace, leaving only the moisture-proof mat and tarp.

Hurry to the reserve area.

I saw a large number of materials neatly stacked in the warehouse, and the storage area was full of hills of food boxes.

The shelves are full of cans, sparkling with metallic luster under the flashlight light!

Ah~~

That's how it feels!

This sense of fullness, this sense of intoxication!

The legs are soft!

This is refreshing that only Survival Party can understand!

...

【Large Food Warehouse】

Material: reinforced concrete

Capacity: 800m3

Loadable modules: extend the shelf life by 100% (100), increase the available space by 100% (50)...

...

"Can the system and modules be upgraded for free?" Looking at these modules, drooling.

Especially the one that increases the shelf life, it's so fragrant!

"Back to the host, this system only provides upgrades, and modules cannot be loaded for free!"

"Oh..."

After Delong Wangshu failed, Zhang Hao felt a little regretful, and immediately let go of his careful thinking.

Too.

It is enough to be able to upgrade the shelter indefinitely!

Is this trying to fart? !

He was looking around in the warehouse. It was dark inside, and he had to use a flashlight. How could he do it?

"System, upgrade the power supply system of the shelter!"

‘The power supply system is being upgraded! ’

"Consumption of 600 meters of wires, meters of cables, 76 light bulbs..."

‘Ding, the power supply system upgrade is complete! ’

The next moment, three headlights illuminate the warehouse, and the entire shelter is lit up, and there is no need for flashlights anymore!

Its daybreak!

...

[Qualified power supply system]

Power source: generator set, photovoltaic power generation system

Loadable modules: reduced short-circuit probability (20), reduced transmission loss (20)...

...

"System! Upgrade the drainage system!"

"System! Build a water circulation system!"

"System! Paint the walls!"

"System! Build a planting area!"

"System! Build a control room!"

"System! Build a generator room!"

"System! Build a super large aquatic product breeding tank!"

"System! You are so easy to use, I love you!"

"..."

...

"System Upgrade..."

‘Ding, the material is insufficient, the upgrade fails, whether to use the survival point to upgrade, the basic material reserve situation, will receive a 46% upgrade reduction. ’

The crisp reminder sounded, awakening Zhang Hao who was addicted to crazy upgrades.

Are some building materials used up?

this...

This is too fast!

But this feeling of unlimited upgrades is really cool!

...

At this time, looking up, the whole shelter has been turned upside down!

Bright white walls, wall lamps, energy-saving lamps, brightly illuminated every corner.

Each area is planned in an orderly manner, and the equipment and materials have all gone where they should go.

"Open the shelter information!"

[Concrete shelter with great potential]

Type: Mixed type of concrete air-raid shelter and rock cavern

Category: Individual

Level: B-

Resident: Zhang Hao

Introduction: An excellent shelter with plenty of materials, complete facilities, huge space, and excellent defense. It is only one cleanup and one bathroom away from Class B. There is still a lot of potential to be tapped!

...

The system did not disappoint!

Even if he was prepared in such a hurry and started so low.

The level of the sanctuary still quickly surpassed the previous life!

This place is not wrong!

Just as he was intoxicated by his doomsday fortress, the situation changed suddenly!

"Yellow alert!"

"A random disaster strikes!"

"Countdown: 00:04:59"

"The types of disasters expected include: volcanic eruptions, meteorite attacks, plate movements, flash floods, sea water intrusion..."

"The expected locations include: Great Xia Federation, Eagle Federation, European Bear Federation, Java Island, Castile Trench, Indian Plateau..."

"Please avoid it!"

"Please avoid it!"
