42: The RV has been successfully upgraded again.

The moment the constant temperature ice crystal transformed into a stream of light in Qin Lin's palm,

The RV began to vibrate violently, more so than ever before.

The commotion of this upgrade was greater than the previous two combined.

It wasn't a reorganization of parts, nor a simple expansion of space.

It was a comprehensive evolution from the inside out, from structure to function.

The entire vehicle was like a sleeping ancient behemoth awakening.

Every piece of metal and every line emitted a resonant low hum.

“Sit tight!”

Qin Lin barked in a low voice, even though he was still lying weakly on the bed.

Su Yuran and Lin Wanwan subconsciously grabbed the edge of the bed.

They felt the floor rising.

The walls were expanding outward, the ceiling grew higher, and everything in their sight was rapidly changing.

First was the space.

Room 001.

Su Yuran's exclusive bedroom grew larger to the naked eye.

The room expanded to twelve square meters, and the bed became a two-meter-wide king-size bed.

Built-in storage cabinets and charging ports appeared at the head of the bed, and a small desk and swivel chair were added near the window.

Most importantly, an entire wall of the room became a dimmable floor-to-ceiling window.

Although there was a wall of snow outside, one could imagine that in a normal environment, this would be an unbeatable scenic view.

The wardrobe changed from a single door to a double door, and its internal space doubled.

The original independent small bathroom disappeared, replaced by a more refined washroom in the corner of the room.

Of course, it still lacked bathing functions.

“My room...” Su Yuran murmured.

“It's become luxurious...”

Almost simultaneously, the neighboring Room 002 also changed.

The room expanded similarly; the bunk beds became two standard single beds placed side-by-side, separated by a nightstand in the middle.

The room also expanded to ten square meters, gaining its own desk and storage space.

The living room underwent the greatest change.

The originally cramped space had now become a true living room.

On the left was a large L-shaped sofa, enough for five or six people to sit at once.

Opposite the sofa, a 75-inch ultra-large display screen was embedded into the wall.

At this moment, it was displaying the RV's status and external environmental data.

Next to the sofa was a small bar counter with two high stools.

Behind the bar was a wine cabinet.

Although it was currently empty, the shelves were already prepared.

The kitchen changed from its original compact form to an open-plan kitchen, connected to the living room.

The induction cooker was upgraded to a double burner, the refrigerator capacity expanded, and a microwave and oven were added.

The countertop was extended, enough for several people to work at once.

Next to the kitchen, a new door appeared.

Qin Lin noticed the door, and with a thought, the System interface popped up:

【New Space: Medical Room (Independent)】

【Equipped with: Basic medicine cabinet, emergency equipment, sterile workstation, hospital bed ×1】

【Function: Can handle common trauma and perform simple first aid】

A Medical Room!

Qin Lin's eyes lit up.

This was too important.

In the Apocalypse, injuries and illness were death threats second only to hunger.

With a Medical Room, the probability of survival would increase significantly.

Unfortunately, there was no doctor.

It seemed he would have to bring a doctor on board.

After all, there was still the Many Children, Many Blessings mission, and a doctor would be an indispensable member.

There was another door on the side of 002, labeled "003".

Qin Lin checked the description:

【New Space: Bedroom No. 003】

【Available modes for each bedroom after upgrade: Single-bed room (1 occupant) / Twin-bed room (2 occupants)】

【The Host can choose the layout before a passenger checks in, or adjust it later】

Qin Lin did not make a choice immediately.

He first turned his attention back to Room 001.

Su Yuran's room information had also updated:

【Bedroom 001 (Bound: Su Yuran)】

【Current Mode: Single-bed room (Changeable)】

【Occupancy Limit: 1 person (Single-bed mode) / 2 people (Twin-bed mode)】

He could choose the mode?

With a thought, Qin Lin selected "Single-bed mode."

This was a bit of selfishness on his part.

Su Yuran was the first person to board the vehicle, the first person he chose after his Rebirth; he wanted to give her a bit of special treatment.

As for Lin Wanwan's room, 002,

The information showed it was a "Twin-bed room (Currently 1 occupant)."

But it wasn't locked and could be adjusted later.

Qin Lin left rooms 002 and 003 alone for now.

He would wait until more people arrived.

The spatial changes lasted for about ten minutes before gradually subsiding.

Then came the functional upgrades.

Qin Lin called up the System interface, and lines of new prompts jumped out:

【Small ecological box unlocked】

【Location: Kitchen side wall】

【Function: Can grow fast-growing vegetables (lettuce, bok choy, cilantro, etc.)】

【Production Cycle: 7-10 days】

【Air purification system upgraded】

【Filtration Level: Intermediate (Can filter dust, pollen, bacteria, some viruses, and biochemical toxins)】

【Autonomous driving function unlocked】

【Modes: Path planning, automatic obstacle avoidance, safe driving】

【Self-generated network function activated】

【Range: Inside the RV and within 50 meters of the perimeter】

【Connectable devices: Mobile phones, tablets, laptops, etc.】

【Restriction: Cannot communicate with the outside world in real-time (external network is paralyzed)】

【Defense capabilities improved】

【Vehicle body armor reinforced to military grade】

【Personnel Buff: "Recovery" Aura】

【Effect: When resting inside the vehicle, wound healing speed +50%, physical recovery speed +30%】

【Energy system upgraded】

【Remaining energy conversion of constant temperature ice crystal: +1000 Energy】

【Current Stored Energy: 2500/∞】

【RV Rank: Lv3 (Mobile Home)】

【Next Level Upgrade Requirement: 5 Intermediate crystal stones】

Qin Lin read through them one by one and let out a long breath.

It was worth it.

Risking his life in the snow these past few days, nearly dying—it was worth it.

With the Medical Room, his current injuries could be better treated.

With the ecological box, fresh vegetables could be supplemented.

With autonomous driving, he could rest during long journeys.

With the self-generated network, there was at least the possibility of receiving external information.

Most importantly was the energy.

2500 points!

“Qin Lin, look...”

Su Yuran pointed out the window.

Qin Lin turned his head.

Through the newly appeared floor-to-ceiling window in Room 001,

Although there was a snow wall outside at the moment, the camera feed from the front of the vehicle showed that the snow waterfall ahead... had stopped.

It didn't gradually weaken; it stopped completely.

The snow that had been pouring down like a waterfall just moments ago had vanished without a trace.

Only ordinary snowflakes drifted from the sky—quiet, sparse, like a winter day before the disaster.

In the area covered by the snow waterfall, those snow piles over twenty meters high that had accumulated for more than half a month were now slowly subsiding.

With no new snow to replenish them, the existing snow began to naturally compact and slide down under the force of gravity.

“The crystal stone...” Lin Wanwan said softly.

“Was it the crystal stone creating the snow waterfall?”

“Most likely,” Qin Lin nodded. “The ability of the constant temperature ice crystal might be related to 'manipulating solid precipitation.' Now that we've taken it, the snow waterfall naturally stopped.”

This was an important discovery.

crystal stones could not only upgrade the RV but might also directly affect the local climate.

If every crystal stone had a similar ability, then the source of this global disaster... Qin Lin didn't dare think too deeply.
