Feng Mengyue's ethereal voice echoed throughout the shelter until it stopped after playing for the third time.
A few brief sentences contained an immense amount of information.
Ruins would randomly appear in the wilderness. Even the glass scavenged from the outskirts could be of this quality. Keeping this message in mind, Su Mo took out two pieces of glass and examined them.
Bulletproof Glass (Excellent): Strength 15, corrosion-resistant, acid-resistant, impact-resistant
Bulletproof Glass (Rare): Strength 50, corrosion-resistant, acid-resistant, impact-resistant. After being worn down by impacts, exposure to light could slowly restore the glass's rigidity.
Compared with Excellent quality, Rare quality not only had terrifyingly greater strength, but also an additional attribute that looked extremely magical.
After thinking it over, Su Mo decided to place the Rare-quality glass on the outermost layer and use the Excellent-quality glass as a barrier to be lowered in the event of a disaster.
After confirming the construction plan once more, Su Mo took a wooden shovel, found the spot directly above the center of the base, and began digging.
Although bulletproof glass possessed extremely high strength, the soil could not withstand such a powerful impact.
"I need to process this pipeline with iron and make a high-strength Iron Pipe. Then I can use the iron to secure the glass. That should work better."
After digging a pit about half a person's height deep, Su Mo first put one unit of Iron Block into it. He then placed two pieces of glass and two mirrors beside it, stacked up all the remaining Iron Blocks, and returned to the base.
He focused his attention and looked toward the upper part of the wall.
Sure enough, the attributes of a new facility appeared before Su Mo's eyes.
Ventilation and Lighting Facility ??? Upgrade Direction One: Periscope structure, pig iron piping, corrosion-resistant coating, waterproof coating. Requires Survival Points (105-90) Upgrade Direction Two: Electric ventilation structure, skylight design, excellent lighting, high air volume. Requires Survival Points (700-65) Evaluation: Calling this pitch-black ceiling a ventilation and lighting facility is enough to make anyone tear their hair out!
The familiar snark, the familiar upgrade method. Su Mo smiled and selected Upgrade Direction One.
After waking up this morning, his Survival Points had recovered to 103. After deducting the 70 points for upgrading the Youneng 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 remaining.
That was just enough to meet Direction One's requirement of 15 points.
A flash of light burst forth, and the earth began to rumble, as though an invisible pair of hands were shaping the terrain.
In Su Mo's field of vision, a hole suddenly split open in the pitch-black ceiling. The Iron Blocks on the ground began to melt, turning into molten iron that rushed into the opening.
Under the system's coating protection, the silvery-white color of the pig iron gradually turned into a hopeful sky blue.
At first, only a little light spilled onto the ground. As time passed, after five or six seconds, a beam of light shot straight into the shelter.
Sunlight! It had been brought in!
The outside air came in as well—crisp and fresh! Standing beneath the pipe, Su Mo looked up and was immediately stabbed painfully in the eyes by the light.
But Su Mo, whose joy was surging at that moment, had no time to care about that. He opened the shelter's wooden door and came to the mound of earth directly above the base.
The hole he had dug had vanished, replaced by a perfectly natural-looking opening.
A 50 cm * 50 cm piece of Bulletproof Glass had been installed on the ground and coated with a specialized camouflage coating.
Combined with its ability to absorb light and repair itself, all the light gathered on the glass was absorbed inward instead of producing strong refraction or scattering, further enhancing its concealment.
Bulletproof Window: Strength 50, coated with optical camouflage and a water-repellent layer, possessing high-performance ventilation and lighting capabilities
Evaluation: Even Old Wang next door can't see what you're doing through a window like this.
"As expected of the system's power! According to my original plan, I was only going to make an opening for ventilation. Now, drilling a tiny hole not only lets air through, but also keeps water out. Excellent!"
After putting away the remaining scraps, Su Mo followed the steps back to the base. After feeling the faintly cool breeze from the lighting opening, he finally relaxed.
On only the second day, he had completed most of the preparations for surviving the first disaster.
He had a steady water source, lighting, and ventilation!
As long as he found a way to dig out a drainage facility during the remaining time, he would basically be able to survive the acid rain disaster.
It was already five in the afternoon. Even if he went outside, he could only chop some wood and gather some plant fibers.
Because of the chameleon's attack that morning, Su Mo planned not to go outside before the scans in the Monster Compendium refreshed.
He took out the Large Rye Bread, split it open with the Stone Axe, soaked it in Psionic Water, and finished eating it.
Su Mo began his evening's work.
Every time Su Mo listed a batch of Psionic Water, he could immediately exchange it through the Trading Market for twice as many Iron Blocks as a single unit at noon.
Upholding the principle of not disrupting the market order, Su Mo asked around after completing a transaction and learned why there were so many Iron Blocks on the market.
Taking Su Mo's own location as an example, the surroundings were mainly rich in wood and plant fibers, which could be obtained with a little physical effort.
As for other things, such as mineral deposits, there was nothing he could do.
Looking around, he could not see the slightest sign that such things existed.
Likewise, just because Su Mo had none here did not mean that other people had none.
Quite a few people had seen enormous exposed mines the moment they descended into this world.
After making a Stone Pickaxe and expending some effort, they could knock quite a few stones off the mountains, and occasionally even dig up Iron Blocks.
With strength in numbers and a large population base, production was also high. That was why so many Iron Blocks flowed into the market, causing their value to depreciate.
In addition, while browsing the market, Su Mo would also buy some items with unknown functions. For example, he had exchanged 100 ml of Psionic Water for a core component of a generator.
Rotor
Quality: Excellent Introduction: A rotating body supported by bearings. Objects such as optical discs that lack their own rotational axis can be considered rotors when rigidly connected to or fitted with an additional shaft.
Evaluation: Spin and leap—I can do it with my eyes closed. Although the rotor was only a small part of a generator, Su Mo was willing to buy it and keep it as a collectible for the bright prospect of restoring the glory of the Age of Civilization.
After buying the rotor, Su Mo had not even had time to admire it when he discovered that someone had listed another good item in the Trading Market's product list.
Large Vegetable Culture Medium! Su Mo's eyes burned with excitement, and he could not help exclaiming joyfully, "Sure enough, over the past few days, most people have been taking out their good stuff to exchange for supplies!"
At present, more than ninety-five percent of the players' food came from supply chests.
As for the Mutated Beasts killed by those powerful individuals, without seasonings or cooking methods, no one would choose to eat such unknown things unless they were on the verge of starvation.
Once they could not find any chests, large numbers of people would probably starve to death within a day or two.
Therefore, building a place capable of producing food over the long term had already become a goal Su Mo had planned from the moment he chose the underground shelter on the first day.
If the Culture Medium had not appeared, Su Mo would have gone out to dig soil himself after another day or two, attempting to build an ecosystem inside the shelter.
Otherwise, who could know whether the soil on the surface would still be able to grow plants after the first disaster—the acid rain—passed?
Looking at the requirements on the trading panel, Su Mo began calculating the supplies in his hands. He was determined to get this Culture Medium.
