Bai Cheng had already roughly figured out some of the patterns of her talent.

To upgrade, she first had to use it.

And speaking of usage, some items are actually very simple to use, such as matches and daggers.

Bai Cheng could quickly max them out and then receive attribute point rewards.

At least she hadn't yet encountered any items that required accumulated time to upgrade.

Looking at the items she already possessed, Bai Cheng's gaze first settled on the ordinary black backpack.

This was also a gift from the 新手禮包 ; the internal space of the backpack wasn't large, not even as big as the school bag she used when she was a student.

After crafting the wooden chest, this item became even more useless; Bai Cheng had hardly ever used it.

Opening the cheng book, she designated the backpack as her upgrade item, and information appeared on the pages.

【Ordinary Black Cloth Bag: 0/10】

“Simple enough!” Bai Cheng's face lit up with joy.

She immediately took out a half-box of chocolates from the wooden chest, grabbed them, put them into the backpack, and then took them out again; usage count +1!

In the blink of an eye, the black backpack in Bai Cheng's hand flashed with a green light, transforming into a gray backpack with more space and more pockets.

【Practical Canvas Bag: 0/20】

Bai Cheng's hands didn't stop; her speed, instead, grew faster and faster.

One minute later, a blue light flashed in her hand; fifteen minutes later, a purple light flashed; half an hour later...

With the last retrieval and use completed, the already exquisite backpack in Bai Cheng's hand flashed with a golden light, finally reaching its top tier.

【Top Tier! Beautiful and Practical Spatial Backpack!】

【You have gained 1 freely allocable attribute point!】

“Spatial Backpack?!” Bai Cheng exclaimed like a broken record.

This thing was simply a divine artifact in the early stages! It directly solved her problem of not being able to transport supplies.

But looking at the not-too-big, not-too-small exquisite backpack in her hand, Bai Cheng couldn't help but complain, “But why is it pink?!”

The pattern on the front wasn't some cute cartoon image, but a speeding train.

“It really is an omnipresent logo...” As for other details, there was no difference from an ordinary backpack.

Through use, Bai Cheng had already understood that this backpack had a total of ten slots, and the maximum stack limit for each slot was only twenty.

“Being able to store up to two hundred units and having no weight limit is already very good.”

Bai Cheng was very satisfied, but she still couldn't prove whether food stored inside would spoil.

Almost instantly, an idea popped into Bai Cheng's mind: to trade this backpack for supplies with other people, and then upgrade it herself through the cheng book, thus allowing her to infinitely farm attribute points.

Moreover, the extra Spatial Backpacks could also be used to trade for employee cards.

But she immediately dismissed her idea.

Firstly, she was still very weak, and her talent should not be easily exposed;

Secondly, a Spatial Backpack was far more useful than a useless employee card, and she didn't want to help these irrelevant people for no reason, as they might become competitors later on.

But if she didn't trade it and kept it for herself?

This backpack was almost useless to all Survivors, and she estimated she could exchange it for quite a lot of supplies with not much effort.

Bai Cheng looked back at her timber; this was the only thing she could offer.

But she still shook her head: “No, cutting trees has become difficult, and I haven't ❀ Nоvеlігht ❀ (Don’t copy, read here) traded for leather yet; this timber is simply not enough...”

Helpless, Bai Cheng could only temporarily give up the idea of farming attribute points, as the top priority was still to quickly reach First Station.

There would be plenty of opportunities to farm attribute points later.

For the second upgrade item, Bai Cheng wanted to choose the wooden chest, because it was almost identical to the backpack; upgrading it would surely result in a spatial chest.

However, the image of the wooden chest did not appear on the cheng book as expected, which surprised Bai Cheng.

“The wooden chest cannot be upgraded?”

She still remembered the rules of the cheng book: any item or tool without an upgrade path could be upgraded through use.

Of course, almost everything could be an item, so the prerequisite was whether it could be used.

And the wooden chest in front of Bai Cheng obviously met both conditions.

“That means the chest has an upgrade path?” Bai Cheng suddenly understood; if it wasn't clear now, it could only mean it hadn't been unlocked yet.

So she shifted her gaze to the solar lantern on the railcar.

The image of the lantern appeared on the cheng book as expected.

【Inferior Solar Lantern: 0/20】

Although it was solar-powered, the lantern also had a switch.

Bai Cheng didn't waste time and immediately started furiously pressing the switch.

Green... Blue... Purple... Gold!

【Top Tier! Infinite Rechargeable Lantern!】

【You have gained 1 freely allocable attribute point!】

The lantern was smaller and brighter than before, entirely black, like an exquisite small lantern, crafted from an unknown metal, and didn't feel heavy at all when held.

Bai Cheng liked it very much; this way, she would no longer have to worry about lighting at night.

Looking around again, she pondered, “What else can be quickly upgraded?”

Disposable items, including food, were not upgradeable and were immediately excluded.

“Stone spear? pulley transmission device, or workbench?”

Bai Cheng had long discovered that items that couldn't be crafted were simpler to upgrade, such as backpacks and daggers.

Whereas craftable items like axes and pickaxes were quite difficult to upgrade, and chests were directly un-upgradeable.

“The stone spear and workbench are both crafted; it's probably impossible to upgrade them to the top tier anytime soon.” Bai Cheng stroked her chin, deep in thought.

But if she chose the pulley transmission device, the upgrade method would most likely involve making her travel...

Bai Cheng stroked her chin and suddenly noticed the clothes she was wearing.

Because it was a white shirt and short sleeves, even though she deliberately tried not to get it dirty, the work she had done in the past two days was more than she had done in the previous month combined, plus the hot weather often made her sweat.

Bai Cheng frowned; her clothes were still a bit dirty.

But she couldn't do anything about it, only suddenly curious: “Can clothes be upgraded?”

With a thought, a white shirt with short sleeves and a blue and white pleated skirt for the lower body immediately appeared on the cheng book in her hand.

“It actually can??” Bai Cheng was greatly surprised, “This is a bit outrageous, isn't it?”

【JK Uniform: 0/1】

“It's just taking off clothes!”

Bai Cheng directly kicked off her shoes and stood on the railcar, undressing as if no one else was around.

Although it was open-air, there was no one around except animals, so she had nothing to be shy about.

Taking them off and putting them back on counted as one use.

Soon, the clothes in her hand also flashed with a golden light, completing their final upgrade.

【Top Tier! Thermostatic and Comfortable Summer Set!】

【You have gained 1 freely allocable attribute point!】

“Set?” Bai Cheng was a bit confused; the clothes in her hand looked no different from before, only the texture had improved.

Not understanding, she chose to check the information.

【Name: Thermostatic and Comfortable Summer Set】

【Quality: Legendary (Bound)】

【Function: Can freely transform into any summer attire, and also features automatic cleaning and thermostatic functions.】

【Evaluation: One piece is better than many!】

Bai Cheng was stunned; she put them on again and felt them. The clothes were not only smoother but also carried a faint coolness, making her no longer feel hot.

With a thought, her JK Uniform indeed transformed into a floral dress.

Bai Cheng spun around, not knowing how to evaluate it, only two words could describe it: “Amazing...”

“What about shoes?”

She repeated the trick, and her black leather shoes could also be upgraded.

As a golden light flashed, Bai Cheng immediately checked the information.

【Name: Versatile Transformable Shoes】

【Function: Can freely transform into various styles of shoes, comes with a self-cleaning function, and slightly reduces stamina consumption.】

“The shoes are even more useful than the clothes!” Bai Cheng then looked down at her undergarments, “Then...”

Soon, a golden light flashed.

【Function: Can freely change letter size.】

Bai Cheng: ???

“What does that mean? Are you looking down on an A-cup?!”
