The box now has become exceptionally exquisite, like a work of art.
Furthermore, the description has changed; before, it could only extend the shelf life of food.
But now, it can extend the shelf life of any item.
Moreover, directly adding a hundred years!
This timeframe is indeed quite significant.
Not only that, just like with the pistol before, upon surpassing level ten, the wooden box turned into a Marvel.
A plain wooden box transformed into a Marvel, capable of extending the shelf life of any item by a hundred years.
This kind of item definitely counts as a treasure.
However, Yang Yuan was frustrated because it did not achieve the effect he desired.
'Let's give it a try first.'
Yang Yuan walked out of the Safe House to retrieve the level ten cooler from the supply drop box and placed it inside the Marvel preservation box, closing the lid.
Unfortunately, the cooling effect still radiated outside and wasn't isolated.
'As expected, it doesn't work.'
He disappointedly took out the cooler and placed it back into the supply drop box.
Jiang Yiyi was practicing with the Crossbow Arrow at the entrance to the Safe House and worriedly asked, seeing him walk back with a troubled expression, "Big Brother, what's wrong?"
"Big Brother is fine." Yang Yuan replied with a smile.
"Then why are you... like this... like this?"
Jiang Yiyi mimicked Yang Yuan's troubled expression, her small eyebrows constantly moving.
Zhao Jiayan, who was whittling short Crossbow Arrows at the Safe House entrance, was amused.
Yang Yuan couldn't help but smile too: "Big Brother is really fine, Yiyi, keep practicing."
He patted the little girl's head, returned to his small compartment, picked up the short knife and the wooden boards he had carved earlier, and prepared to make a new one.
During the process of making the new box, he seriously thought about his superpower for the first time.
'Conceptual System ability...'
'Concept... does it mean the kind of concept I'm thinking of?'
Yang Yuan pondered: 'Then I'll add a concept to this unfinished box first and see if it can affect the information once it's formed.'
With this thought, he immediately took action.
This time, he was making the same model of a box with a movable lid as before.
But during the making process, he kept thinking in his heart that what he was making was a box that could isolate all sorts of breaths, a box that could isolate radiation, a box that could isolate the aura of supernatural items.
Moreover, after making it, he carved the word 'Isolation' on the lid.
A miraculous thing happened; after the box was made and before the word was carved, no data was produced, but once he had carved the word 'Isolation', the data instantly appeared:
[(Pseudo) Isolation Box Lv.1: 0/1 (A toy wooden box for playing house; cannot be upgraded)]
Yang Yuan smiled.
Although the introduction mentioned it was just a toy for playing house, what did that matter?
As long as the name was what he wanted, that was enough.
'The potential of my superpower... is probably greater than I previously anticipated!'
He smiled and resumed gaining experience in the same way as before.
Sure enough, the way this box gained experience was identical to the previous one.
Thanks to the previous experience, this time he avoided unnecessary effort, stopped when reaching 1,029 experience points, and started upgrading the box.
[(Pseudo) Isolation Box Lv.1: 1029/1 (Upgradeable)]
...
[(Pseudo) Isolation Box Lv.2: 1028/2 (Upgradeable)]
...
[(Pseudo) Isolation Box Lv.3: 1026/4 (Upgradeable)]
...
[Isolation Box Lv.4: 1022/8 (Can isolate radiation from low-level radiation-emitting objects; Upgradeable)]
Yang Yuan laughed heartily.
'Indeed, by adding a concept initially and believing it has such potential, I can then slowly upgrade it.'
The Conceptual Superpower is quite awesome!
However, it seems that to imbue an item with a concept, it first needs to take on its corresponding shape.
Otherwise, even if you imbue a stone with a concept, naming it a spaceship, it would be of no use.
Moreover, for pre-existing concepts, such as firearms, there is no need for extra effort.
Because those items, in his own and the public's concept, are shooting tools and won't become tools for writing or cooking.
Unless specifically designed with such features, and then made into the shape of firearms, but that would just be redundant, something only a mentally unstable person would do.
Wasting no time, Yang Yuan continued upgrading the box.
After all, a level-4 Isolation Box was not sufficient, only being capable of isolating radiation from low-level radiation-emitting objects.
Whereas the cooler was already considered a supernatural item, just a step away from being a Marvel.
...
[Isolation Box Lv.5: 1014/16 (...; Upgradeable)]
...
[Isolation Box Lv.6: 998/32 (Upgradeable)]
...
[Isolation Box Lv.7: 966/64 (Can isolate radiation from mid-level radiation-emitting objects; Upgradeable)]
The level-7 Isolation Box had its effectiveness increased again.
Yang Yuan continued upgrading:
[Isolation Box Lv.8: 902/128 (Upgradeable)]
...
[Isolation Box Lv.9: 744/256 (Upgradeable)]
...
[Isolation Box Lv.10: 518/512 (Can isolate radiation from high-level radiation-emitting objects; Upgradeable)]
Now, it can isolate radiation from high-level radiation-emitting objects.
Yang Yuan was eager, upgrading it once more.
As the latest upgrade concluded, the originally crude and shoddy box, through successive upgrades, became increasingly exquisite.
Following this latest upgrade, it transformed further to resemble a work of art, and though it wasn't dazzling, it was clearly not an ordinary object at first glance:
[Marvel·Isolation Box Lv.11: 0/2 (Can isolate supernatural items with a level not exceeding that of the box itself, including but not limited to aura, radiation, etc.; Non-upgradeable)]
Personal experience incremented by one point again.
"Success!"
Yang Yuan was delighted, hurriedly left the Safe House, and ran to the supply drop box.
Due to the differing data, he immediately spotted the level ten cooler among hundreds of others, took it out, placed it inside the Marvel box, and shut the lid.
Instantly, the radiating power vanished, and the external temperature of over fifty degrees enveloped them, making it feel as if they were inside a furnace.
At the Safe House entrance, Zhao Jiayan and Jiang Yiyi were both stunned.
"It's so hot..."
"What happened?"
The two women hurriedly looked over at Yang Yuan, thinking there might be an issue with the cooler.
Yang Yuan held up the Isolation Box and said to them, "I made a box that can isolate the cooler's effect, so we don't have to worry about creating a whirlwind effect again."
The two women realized.
Zhao Jiayan happily said, "Your ability is really handy, which surely makes things more convenient. If we encounter objects inconvenient to display, we can put them in that box."
"Yes indeed."
Yang Yuan nodded, but at present, there wasn't a need for it.
So he returned the cooler to the supply drop box to continue storing water.
By now, the supply drop box had accumulated thirty or forty pounds of water. The ground nearby was even damp as if it had rained.
In fact, it truly was like raining since within the cooling range of the cooler, there was a drizzle.
It was due to the excessively high levels of moisture in the air.
"You keep these two boxes for now and store them with the other supplies."
Yang Yuan handed both boxes to Zhao Jiayan: "This one with writing is the Isolation Box, the other is the Preservation Box. This Preservation Box can extend the shelf life of any item by a hundred years."
"A hundred years?!" Zhao Jiayan was astonished, instantly thinking of some difficult-to-preserve Spiritual Objects in this world.
