Facilities Complete! Competing Culture Mediums!

Feng Mengyue's ethereal voice echoed continuously in the Shelter, stopping after playing for the third time.

The short sentences contained a wealth of information.

Ruins will randomly refresh in the wilderness, and even the glass scavenged from the periphery is of this quality. Keeping this message in mind, Su Mo took out the two pieces of glass and examined them.

[Bulletproof Glass (Fine): Strength 15, corrosion-resistant, acid-resistant, impact-resistant]

[Bulletproof Glass (Rare): Strength 50, corrosion-resistant, acid-resistant, impact-resistant, after impact wear, exposure to light can slowly restore the glass's rigidity]

Compared to the fine quality, the rare quality not only had a more terrifying strength, but also had an attribute that seemed extremely magical.

After thinking about it, Su Mo decided to place the rare quality glass on the outermost layer and use the fine quality as a baffle, to be lowered in case of disaster.

After confirming the construction plan again, Su Mo took the wooden shovel and started digging directly above the center of the base.

Bulletproof Glass had extremely high strength, but the soil could not withstand such a large impact.

"This pipe needs to be processed with iron to make a high-strength Iron Pipe. Then, the glass can be fixed with iron, which would be better."

After digging a pit about half a person tall, Su Mo first placed a unit of iron blocks in it, then placed the two pieces of glass and two mirrors next to it, and piled up all the remaining iron blocks before returning to the base.

Focusing his attention, he looked at the top of the wall.

Sure enough, the new facility attributes appeared before Su Mo's eyes.

[Ventilation and Lighting Facility???]

Upgrade Option 1: Periscope Structure, Pig Iron Pipe, Corrosion-Resistant Coating, Waterproof Coating, requires spending Survival Points (105-90)

Upgrade Option 2: Electric Ventilation Structure, Skylight Design, Good Lighting, Sufficient Airflow, requires spending Survival Points (700-65)

Evaluation: Calling this dark ceiling a Ventilation and Lighting Facility is truly frustrating!

The familiar complaints, the familiar upgrade methods, Su Mo smiled and chose Upgrade Option 1.

After waking up this morning, his Survival Points had recovered to 103, and after deducting the 70 points for upgrading the Psionic Water Well, he had 33 points left.

After deducting 10 points for two Beech Spears and 5 points for the Pottery Armor, he currently had 18 Survival Points left.

Just enough for the 15 points required for Option 1.

A flash of light, and the earth began to rumble, as if a pair of invisible hands were shaping the terrain.

In Su Mo's vision, the originally dark ceiling suddenly cracked open, and the iron blocks placed on the ground began to melt, turning into molten iron and rushing into the gap.

The silver-white of the pig iron gradually turned into a hopeful sky blue under the protection of the system's coating.

At first, only a little light sprinkled on the ground, but as time passed, after five or six seconds, a beam of light went straight into the Shelter.

Sunlight! It came in!

Also coming in was the crisp, fresh air from the outside! Standing under the pipe, Su Mo looked up and was immediately stung by the light.

But at this time, Su Mo, whose heart was filled with joy, didn't care about these things. He opened the Wooden Door of the Shelter and came to the mound directly above the base.

The pit he had dug out had disappeared, replaced by a naturally formed small opening.

The 50cm*50cm Bulletproof Glass was set up on the ground, coated with a special camouflage coating.

In addition, with the characteristic of absorbing light to repair itself, all the light converged on the glass without producing strong refraction and scattering, but was completely absorbed inward, further enhancing the concealment.

[Bulletproof Window: Strength 50, coated with optical camouflage coating, water-repellent layer, has dual high-performance characteristics of air permeability and light transmission]

Evaluation: With such a window, even the nosy neighbor next door can't see what you're doing.

"As expected of the system's power, my original idea was to open a hole for ventilation, but now micro-distance perforated ventilation not only allows air to pass through, but also isolates water, that's great!"

Putting away the remaining scraps, he returned to the base along the steps, and after feeling the slight cool breeze from the light opening, Su Mo finally felt relieved.

In just the second day, he had completed most of the work to prevent the first disaster.

He had a continuous source of water, light, and ventilation!

As long as he could find a way to dig out a drainage facility in the remaining time, he would basically be able to survive the Acid Rain disaster.

It was already five o'clock in the afternoon, and even if he went out, he could only chop some wood and plant fiber.

Because of the Chameleon attack in the morning, Su Mo didn't plan to go out until the scan count in the Monster Compendium was refreshed.

Taking out a Large Rye Bread, he split it open with the Stone Axe, soaked it in Psionic Water, and ate it.

Su Mo began his evening work.

Every time Su Mo listed a batch of Psionic Water, he could immediately exchange it for twice as many Iron Blocks as he could at noon from the trading market.

Adhering to the principle of not disrupting market order, after completing a transaction, Su Mo inquired about why there were so many Iron Blocks on the market.

Taking Su Mo's own location as an example, the surrounding area was mainly wood and plant fiber, which could be obtained with a little physical effort.

Other things, such as minerals, were out of the question.

Looking around, there was no trace of such things existing.

Similarly, just because Su Mo didn't have them didn't mean others didn't.

Quite a few people, upon arriving in this world, could see huge mines exposed on the surface.

Making a Stone Pickaxe and putting in some effort, they could knock off a lot of stones from the mine, and occasionally even dig up Iron Blocks.

Many hands make light work, and with a large base, the output was also large, which was why a large number of Iron Blocks flowed into the market, leading to devaluation.

In addition, while wandering the market, Su Mo would also acquire some items with unknown functions. For example, he exchanged 100ml of Psionic Water for the core component of a generator.

[Rotor]

Quality: Excellent
Introduction: A rotating body supported by bearings, objects such as discs that do not have a rotating shaft themselves. When it adopts a rigid connection or an additional shaft, it can be regarded as a Rotor.
Evaluation: Rotating, jumping, I close my eyes.

Although the Rotor was only a small part of the generator, Su Mo was willing to buy it and collect it for the bright prospect of restoring the glory of the civilized era.

After buying the Rotor, Su Mo didn't even have time to admire it before he discovered that someone had listed a good item in the trading market's product list.

Large Vegetable Culture Medium! Su Mo's eyes were eager, and he couldn't help but rejoice, "As expected, most people will take out good things to exchange for supplies these days!"

Currently, more than 95% of the players' food comes from the supply boxes.

As for those tough guys who killed mutated beasts, because they lacked seasonings and cooking methods, no one would choose to eat such unknown things unless they were starving to death.

Once they couldn't find a supply box, a large number of people would probably starve to death in a day or two.

Therefore, building a place that could produce food for a long time had been a goal planned in Su Mo's mind from the moment he chose the underground Shelter.

Even if the Culture Medium hadn't appeared, in a day or two, Su Mo would have taken the initiative to go out and dig soil, trying to build an ecological environment in the Shelter.

Otherwise, who knew if the soil on the surface could still cultivate plant growth after the first disaster, Acid Rain.

Looking at the demands on the trading panel, Su Mo began to calculate the supplies in his hand, determined to take down this Culture Medium.
