9: Chapter 9 Upgrade Blueprints!

He first opened ten black iron treasure chests.

[Obtained: Green Shade Water Purifier Manufacturing Blueprint (Green) x 1]

Detailed data: Utilizing the principle of high-altitude cloud condensation, it can produce 500ml of pure drinking water per hour.

Note: As long as you are flying, you will no longer need to search for water sources.

[Obtained: High-Efficiency Photovoltaic Solar Panel Blueprint (Green) x 1]

Detailed data: When there is sufficient sunlight daily, it can produce 10 kWh of electricity, stored in the vehicle's capacitor, capable of powering all Tier 2 and below household appliances.

[Obtained: Integrated Automatic Bathroom Module (Green) x 1]

Detailed data: Occupies 2 square meters, comes with an internal water circulation purification system, and requires only three liters of recycled water for one shower.

Note: After use, gain a two-hour buff, with SAN value recovery speed increased by 10%.

"These are all good things!"

Zhou An's eyes gleamed as he watched. The water purifier and solar panels perfectly solved his logistics consumption, and that bathroom allowed him to finally bid farewell to the awkwardness of sponge baths.

Finally, Zhou An's gaze fell upon that chest radiating a quaint, bronze luster.

He held his breath and pressed the open button firmly.

A dazzling cyan light exploded outward!

[Obtained: Cloud Top Fortress Upgrade Blueprint x 1]

[System Prompt: This blueprint can upgrade your vehicle from LV1 to LV2!]

Zhou An couldn't wait to look at the list of materials required for the upgrade, and even though he was mentally prepared, he was still startled by that string of numbers:

Upgrade Requirements:

Level 2 Steel: 1500 units

Level 2 Composite Rubber: 1000 units

High-Density Energy Core: 200 units

...

"Everything starts at a thousand units, and it even requires Level 2 metal..."

Zhou An glanced at his newly stocked resource statistics. Thanks to the Level 2 materials he had just opened from those two hundred-plus blind boxes, plus his previous accumulation from the material rain, he had actually managed to gather over eight hundred units of Level 2 steel.

"Still missing about half the Level 2 metal materials."

"A few more days of scavenging, and I'll be able to upgrade to LV2."

"Those people are flying blindly in front, crashing their vehicles just to snatch a single chest, and in the end, it all benefits me, the one scavenging in the back."

There was one last bronze treasure chest lying quietly in the center of the cabin. Zhou An took a deep breath and solemnly pressed his hands onto the edge of the chest lid.

[bronze treasure chest is opening...]

Three vials filled with translucent liquid floated quietly in the air.

[Obtained: Low-Level Speed Enhancement Potion (Green) x 1]

[Obtained: Low-Level Physical Enhancement Potion (Green) x 1]

[Obtained: Instant Powerful Recovery Potion (Blue) x 1]

Note (Instant Powerful Recovery Potion): As long as it is not a fatal wound, after injection, it can restore a large amount of bodily function within thirty minutes.

Zhou An's pupils contracted, and he hurriedly tucked that powerful recovery potion into his most secure inner pocket.

Afterward, he picked up those two green enhancement potions and, without hesitation, directly injected them into his arm.

A scalding hot current instantly swept through his entire body along his blood vessels. Zhou An felt his bones emit a series of teeth-aching cracking sounds, while his muscle fibers were frantically tearing, restructuring, and compressing.

Two minutes later, the heat wave receded, and he snapped his eyes open.

[System Prompt: Host's physical fitness has been improved!]

[Personal Combat Rank: Tier 2]

Evaluation: Your muscle density and neural reaction speed have completely surpassed the limits of Earth humans. Even a top-tier special forces soldier or Olympic champion in their prime would be like a child before you.

Zhou An clenched his fist, feeling the air pressure explode between his knuckles, and was very satisfied.

...

Night fell.

Zhou An did not rest; instead, while in high spirits, he began major infrastructure construction.

He installed those high-efficiency photovoltaic solar panels on the roof of the cabin and installed the Green Shade Water Purifier on the outside of the kitchen. With the "zizzing" sound of mechanical welding, the condensation pipes began to extract pure water droplets in the low temperatures of the ten-thousand-meter altitude.

The materials used to install these were not much; what he had opened earlier was more than enough.

And the most satisfying thing for him was the automatic bathroom module.

Walking into the two-square-meter bathroom, as the warm water gushed out from the showerhead, Zhou An let out a long sigh.

In this apocalyptic sky survival, being able to take a hot shower was simply a noble-like luxury.

After washing away the blood and grime, Zhou An changed into a clean set of linen clothes, feeling refreshed.

"The hardware is all set, I'm just missing a bed. I can't keep sleeping on the cold metal floor."

Zhou An opened the system trading mall and began a precise search for bed blueprints.

Right now, most players were still struggling at the subsistence level; although life-related blueprints were precious, they were often put up for sale by people in urgent need of water and fuel.

Soon, a blueprint caught his eye:

[Multi-functional Ergonomic Recovery Bed Blueprint (Green)]

Attributes: Stamina recovery efficiency during sleep increased by 20%, SAN value recovers an additional 1 point per hour.

Seller: Chen Youyou.

Zhou An initiated a private chat directly.

"Bed blueprint, how are you selling it?"

Chen Youyou replied instantly, sounding somewhat urgent: "Do you have food or water? Or warm clothes? I have the blueprint, but I'm freezing to death right now, and my vehicle's fuel is sounding an alarm!"

Zhou An glanced at the mountain of fuel and the newly produced pure water in his warehouse, then replied: "20 liters of pure water for your blueprint."

The other side was silent for a full half-minute, clearly stunned by this massive sum. 20 liters of pure water was life-saving capital.

"That's too much... You're not joking, are you?"

Chen Youyou probed, somewhat incredulously.

"I don't have time to haggle. If you agree, we trade; if not, I'll find someone else."

Zhou An's tone was flat. The effects of this bed were quite good, but it seemed he had overbid on his first offer.

"Deal! Deal!"

Fearing he might change his mind, Chen Youyou immediately initiated the trade request.

Zhou An took the opportunity to use another 20 liters of water to sweep the trading hall, exchanging it for several sets of brand-new pure cotton clothes and thick down quilts.

Returning to the inner cabin, Zhou An consumed materials and selected [Build].

A flash of white light passed, and a simple-looking single bed with a memory foam mattress appeared in a corner of the inner cabin.

Zhou An threw himself onto it, sinking into the soft bedding. That feeling of being tightly wrapped and the warmth of the down quilt allowed his accumulated mental exhaustion from the past few days to be released instantly.

"Whew—"

He turned his head to the side, looking at the brilliant and dangerous starry sky outside the window.

"Finally, I have a bed."

He rolled around on the bed a few times before adjusting his sleeping posture.

Zhou An closed his eyes, and under the dual protection of his Tier 2 body and the comfortable environment, he fell into the deepest and most peaceful slumber since he had transmigrated.
