Backpack capacity insufficient, material upgrade

...The sky faded from ink-black, a sliver of cold, pale white bleeding into it.

The long highway revealed itself under the dim light, a black ribbon piercing straight toward the edge of the horizon.

The world outside the window was nothing but vast wilderness and snow; no trees, no buildings. The earth was blanketed in white, and the distant horizon was terrifyingly straight, pressing heavily upon the entire world.

A geothermal core prototype was placed on the floor of the safety compartment.

It had raised the temperature of the entire compartment to around 20 degrees Celsius, making it quite warm.

Of course, Chen Yu wasn't stingy with the range; he had it envelop the entire vehicle, including the exterior.

[red luan Identified: Yang Kexin]

[red luan Number: 3]

[Connection Nature: Value Pact, physiological connection]

[Connection Depth: Lv.11]

[Current Effective Multiplier: 110x]

[red luan Talent: A-Rank 「Ironware Crafting」(Can simulate crafting ironware ×1 daily)]

[Talent Return: Every summoning yields simulated Ironware Crafting ×110]

Chen Yu lay on the bed, looking at the latest red luan information, lost in thought.

The physiological connection was easy enough to understand, but this 'Value Pact' was appearing for the first time.

Moreover, Yang Kexin's red luan level was soaring.

In an instant, she had surpassed Wang Mengmeng to reach Level 11.

Currently, his three red luan levels were—

Deng Yuxin (Subconscious Safety Entrustment/physiological connection): Lv.17

Wang Mengmeng (Domestication Connection): Lv.6

Yang Kexin (Value Pact/physiological connection): Lv.11

The return from Level 11 was as high as 110 times... "110 pieces of ironware every day?"

"That's a bit abstract..."

Chen Yu repeated in a low voice, his fingers tapping on the edge of the bed.

The reason he had invited Yang Kexin onto the vehicle wasn't just because of the ironware returned by red luan.

The most important reason,

was actually that her talent had strategic significance.

But now, those 110 daily pieces of ironware would ultimately end up in his backpack.

There had to be a solution... sell them all?

In the early stages, when most passengers still lacked weapons, ironware was indeed a hard currency.

It could easily be traded for food, water, and medicine, but the problem was... the weapon market would saturate.

Road to Survival wasn't a static game; as station missions progressed, people would always find ways to get basic equipment. The demand for axes, crowbars, and knives would only decrease.

More importantly, dumping a large amount of standardized ironware was also quite troublesome.

Just like his first trade with Yang Kexin, she only dared to say she had found them by chance.

Not to mention Chen Yu would be selling hundreds at a time.

"Tsk, I never thought the day would come where having too many supplies and no space to store them would be a problem..."

"I need to prepare more rope and turn individual weapons into bundles..."

Chen Yu pondered.

"Chen Yu?"

"These are from the Public Backpack; the Class Monitor must have scavenged them, right?"

Yang Kexin had already changed into new clothes.

The previous outfit had been accidentally ruined just now.

Now, Yang Kexin was wearing a hooded knit cardigan. The V-neck revealed a pure white camisole and a section of delicate collarbone, while her lower half featured high-waisted shorts that perfectly showcased her startlingly long legs.

Being a dance student, she already had a superior physique, and the high-waisted design further elongated the visual of her legs.

Even Chen Yu couldn't help but feel a slight stir.

Yang Kexin's face flushed, but she was very happy.

She had chosen this outfit with careful thought, because she had noticed... Chen Yu seemed quite interested in her legs.

"Kexin, craft a blade for me."

Chen Yu leaned against the headboard and spoke calmly.

Yang Kexin immediately entered her professional state: "What kind of blade do you need? Approximate size, purpose?"

Chen Yu gestured in the air with his fingertips: "About a meter in total length. It needs to be swingable in narrow environments. The blade should be thick and heavy, but the center of gravity needs to be forward so it has power when hacking down."

Yang Kexin listened while tracing the outline in the air with her finger: "A straight blade, leaning towards a machete design. Understood, I'll give it a try..."

The next moment.

Her expression became focused.

Chen Yu could feel some invisible energy converging toward her palms.

After about a dozen seconds, Yang Kexin opened her eyes and held her hands out, palms facing each other.

"Phew."

A cluster of silver halo emerged. In the center of the halo, the faint shape of a long blade began to form.

Chen Yu narrowed his eyes; this scene was truly magical.

Three seconds later... Yang Kexin's palms slammed together!

“Buzz—!”

Silver light flashed brilliantly!

A tactical long blade gleaming with a cold, sharp light suddenly appeared in her hands!

At the same time... a prompt suddenly rang out in Chen Yu's mind:

[red luan Harvest: Simulated Ironware Crafting ×1]

[Talent Return: Simulated Ironware Crafting ×110]

[Warning: Insufficient Backpack Capacity]

[110 pieces of Simulated Ironware cannot be stored]

Chen Yu frowned and immediately pulled up his personal backpack interface.

Sure enough, after robbing so many people, his supplies were indeed far too abundant.

Various supplies were packed densely into the space, with only the very last slot remaining empty.

He really couldn't fit 110 pieces of ironware.

Just as Chen Yu was preparing to move some items into the Public Backpack.

The talent notification rang out again:

[Unable to store talent supplies]

[Exchanging for equivalent supplies]

[Material Upgrade: Impure Iron → Dense Alloy Steel]

[Talent Return: Simulated Steelware Crafting]

“???”

Chen Yu's expression changed. It could do that?

Return supplies that couldn't be stored... would actually trigger an automatic equivalent exchange?

110 iron long blades had been refined into a single Dense Alloy Steel blade?

His surprise was interpreted completely differently by Yang Kexin!

Looking at Chen Yu's expression, a hint of small pride immediately rose on her cheeks!

Chen Yu must really like the things made with her A-Rank Talent 「Ingenious Conception」!

She puffed out her chest slightly: "Um... Chen Yu, what do you think?"

Before she could finish her sentence.

She saw the corners of Chen Yu's mouth turn up: "Very good."

Then, without hesitation, he reached out and grabbed her arm.

"Eh?"

Before Yang Kexin could react, she was half-pulled and half-pushed out of the safety compartment.

“Bang!”

The metal door shut decisively behind her.

Yang Kexin stood outside the compartment with a blank face.

“???”

Wait... what exactly was going on?

Hadn't their 'deep contact' just now gone well?? Why was she kicked out in the blink of an eye??

Inside the carriage.

Zhang Wanyue, Deng Yuxin, Li Meng Yao, and Wang Mengmeng, who had heard the commotion, all turned their heads.

Their gazes fell on her in unison: "..."

Meanwhile, inside the safety compartment.

Chen Yu directly took out the Dense Alloy Steel blade.

"If a hundred iron blades synthesize into a steel blade."

"Then... what about ten thousand?"
