The gas pump's generous rewards filled Gu Su with delight.
He quickly stowed the Oil Sprayer, Highly Concentrated Corruption Oil, and the other items in his storage space. His fingertips moved with barely contained urgency.
Without waiting for the skeletons to finish clearing the battlefield, he set off at a brisk pace toward the small supermarket behind the gas station.
At that moment, every inch of the gas station looked like a pleasant surprise to him.
The small supermarket that had been protected for so long by the Oil Depot Slug's power was no exception. Its spoils would surely be no less valuable than what he'd found by the gas pumps.
He kicked open the supermarket door, which hung crookedly from its frame. Its creak broke the stillness that had settled over the battlefield.
Gu Su's gaze swept across the empty supermarket with the precision of a hawk, instantly locking onto the checkout counter in the corner, where white light was flashing incessantly.
Without wasting a moment, he strode over and yanked open the counter's small drawer.
The instant the drawer opened, a crisp "ding, ding, ding" rang through the empty supermarket.
Countless gleaming gold coins burst from the drawer like a fountain breaking free of its restraints. They clattered onto the black-oil-stained floor, their tiny golden glints shimmering through the dim supermarket. In moments, they'd formed a small pile, so dazzling that it was impossible to look away.
The coins poured out for a full half minute before gradually slowing to a stop.
Almost simultaneously, the familiar system prompt sounded in Gu Su's ear.
[You opened the White Checkout Counter and obtained 2,466 coins.]
Gu Su looked down at the heavy pile of glittering coins on the floor, and a broad grin spread across his face.
The checkout counter's rewards were simple and straightforward—and coins were exactly what he needed most right now.
His fingers twitched as he quickly calculated in his mind:
The 2,466 coins from the checkout counter, plus the 554 from the oil depot chest, plus the 382 he'd already accumulated from the Graveyard Demon—all together, they came to a whopping 3,402 coins!
The number made Gu Su's heart jolt, and an uncontrollable thrill surged through him.
At last, he had enough coins to upgrade the Graveyard Demon!
A major worry that had weighed on him for so long had finally been put to rest. Relief and joy spread through his body with every beat of his heart.
He reined in his excitement, turned to the skeletons waiting beside him, and gestured for them to gather up every coin on the floor and stow them away safely.
Once all the coins had been collected, Gu Su's gaze drifted to the empty shelves in the supermarket.
The shelves had long since been stripped bare, with nothing left on them.
But thanks to the Oil Depot Slug's protective power, they remained in remarkably good condition.
The metal frames gleamed smoothly, without a trace of rust.
The wooden shelves were thick and sturdy, showing no signs of rot or mold.
It was easy to see that both the wood and the metal looked as good as new.
Gu Su didn't even need to take them apart to know they were made of excellent materials—far better than anything he'd salvaged from wrecked cars or the mall.
Gu Su gently ran a hand over the cold shelves, already certain what to do with them.
These materials definitely shouldn't be used to make weapons or equipment. That would be a terrible waste.
They should instead be used to upgrade the buildings in his territory. They would surely give the Graveyard Demon's upgrade a substantial boost, improving the territory's defenses and capabilities.
With that in mind, Gu Su beckoned outside once more. Another group of skeletons came in and began dismantling the shelves, preparing to pack them up and bring them back.
After the shelves had been dealt with, Gu Su finally turned his attention to the small supermarket's last piece of loot.
The unusually conspicuous "oil painting" on the wall.
The painting was brightly colored and looked brand-new. Most importantly, it showed farmers harvesting crops in a field.
Its pristine condition and the scene it depicted were both completely at odds with the shabby, empty, oil-stained supermarket around it. It looked distinctly out of place.
Gu Su strode over and pulled the painting off the wall.
The instant he touched the canvas, the paint on its surface vanished like a receding tide, revealing a material beneath that glimmered with a faint blue light.
The once-beautiful painting had become a scribbled sheet covered in writing.
At the same time, a prompt sounded.
[Simple Soilless Cultivation Technology blueprint discovered. Would you like to record this blueprint in the construction list?]
This wasn't an oil painting at all—it was an extremely precious blueprint!
Hearing the prompt, Gu Su immediately understood.
It was a blueprint.
In the game, plans and schematics were clearly divided into categories: scrolls, forging diagrams, manuals, architectural plans, and blueprints, each with its own purpose.
Scrolls were used to learn magic skills, forging diagrams to craft weapons and equipment, and manuals were much like instruction booklets.
Architectural plans and blueprints could only be put to their full use by players with an earth-type cheat ability.
Architectural plans allowed players to directly construct the corresponding buildings in their territory, shelter, or mobile city.
Blueprints, on the other hand, were used specifically to modify territories, shelters, and mobile cities by adding various functions.
Without a blueprint, any modifications were what players called "unauthorized alterations" or "wild modifications."
The results of such changes were completely unpredictable. With luck, they might improve things; with bad luck, they could backfire and even damage the foundations of a territory.
It went without saying how important architectural plans and blueprints were to an earth-type player like him who had a Graveyard Demon.
They were treasures one could only hope to stumble across, never seek out.
If this thing got away, it would be an absolute joke.
Gu Su blurted out his answer, barely able to hide his eagerness and delight, as if afraid the surprise would disappear if he waited a moment longer.
"Record it!"
As soon as he spoke, detailed information about the blueprint appeared clearly in Gu Su's mind like a stream of data.
After that, as long as he had enough materials, he could go to the tent to build or make modifications, without any further hassle.
[Simple Soilless Cultivation Technology: Spend 1 unit of wood and 1 unit of stone to build a simple hydroponic rack. It can grow six or more kinds of plants at once, increase the seedling emergence rate by 20%, speed up plant growth by 35%, and has a 15% chance of improving plant quality.]
Looking at the information that had appeared before him, Gu Su smiled.
What a great find.
Other people might see soilless cultivation technology as a way to grow vegetables and grain so the residents of their territory wouldn't go hungry.
But Gu Su's territory was populated by undead. They didn't need to eat.
Aside from growing food for his own consumption, the most important use of this technology was to cultivate the special seeds Gu Su had found.
That was the greatest reward of all.
