I became a god by treasure hunting after arriving 500 years early

This door is extremely sturdy, 22 centimeters thick, weighing almost 12 tons. It's difficult to break through from the outside, but much easier to dismantle from the inside.

It took about two hours, and Lu Yuan managed to place this several-ton door into the Storage Space.

"Consider it as a bit of interest!" He raised his eyebrows, the value of this door alone is 1400 Spirit Essence!

Then he removed the warning plaque hanging at the door.

"An empty little room, although a bit strange, humans and dwarfs basically have no way to delve into its contents."

He checked several times in this small ruin, found no hidden passages or chambers, and then slowly retreated.

The cold wind and liquid nitrogen raindrops came rushing, but in contrast to the solitary and deathly quiet civilization ruins, everything was once again a vibrant scene.

"How is the harvest?" Conch Girl was waiting by the window for him, her smile bright and sunny.

"I discovered some answers in that secret chamber." Lu Yuan didn't reveal much, "Almost got attacked by a [Ghost], haha."

Conch Girl was naturally sensible and didn't randomly ask questions, just gazed at him with big eyes.

She never wished for Lu Yuan to do anything too dangerous.

Lu Yuan changed the subject: "Humans also need to stick to the established goals, develop step by step with a solid footing."

"Oh, by the way, I also moved a Legendary door, it's somewhat of a status symbol. I'm planning to modify it a bit and install it on my [Temple of Greed]. Now everything is ready, just waiting for the east wind."

"When will it officially open?"

"It should be soon! The 'Craftsmanship' ability is my most handy ability, I've basically found its Rule Imprint and am confident I can fully replicate it."

Lu Yuan felt a sense of urgency within: "Just because of the existence of 'Field Industrialization', craftsmen are more in demand than ever, it should sell well."

"In addition, I need to replicate several Divine Skills to boost the facade."

"I plan to prioritize replicating [Super Thinking], [Translation Ability], [Animal Affinity], and [Plant Affinity]. Their prices won't be too high, costing 1-2 Luck to replicate, selling for 5-10 Luck, 500% profit isn't excessive, right?"

Abilities related to production are always in short supply.

The effects of Animal Affinity and Plant Affinity can be combined with the field to achieve a "1+1>2" effect.

With the creation of the Lücao Trading Market, some auxiliary abilities and scientific abilities have also become popular.

Considering the purchasing power of various civilizations, it can't be too expensive. 5-10 Luck should be the maximum price most civilizations can accept (much higher than the market price).

"Besides, I will also sell minerals, converting personal property into 'Luck'. The price can be slightly lower, as long as it can be converted into luck."

Spirit Essence, Lu Yuan keeps about 50,000, which is basically enough.

The accumulation of "Luck" really is too slow, so Lu Yuan has turned his attention in this direction.

The minerals at the Northern Extreme are so abundant, digging up ten thousand Spirit Essence is actually easy. The crystals on the Giant Crystal Turtle can also be used for trading.

Even if converted at a 50:1 ratio, it can be sold for two to three thousand, which is quite a good number.

"Also, I can sell [Temple], selling a [Temple] for two to three hundred Civilization Points shouldn't be a problem, right?" Lu Yuan gritted his teeth.

The strategic value of [Temple] lies in long-distance teleportation, which is invaluable for civilizations in need.

The Human 18th Civilization will definitely buy [Temple]!

And who knows, even the Dwarf Civilization, Long-haired Civilization might have needs too.

Therefore, Lu Yuan urgently needs to perfect the Immortal Palace and find a way to conceal the operation of [Temple].

...

...

While pondering, with a gentle "clatter" sound, the Giant Crystal Turtle returned from the deep sea, excitedly calling out "Wagaga" upon seeing the two.

It spat out some strange sea creatures from its mouth, baring its teeth as it tried to please.

Lu Yuan glanced at these deep-sea creatures reluctantly, they might have grown by relying on the geothermal energy of the sea floor, all bizarrely shaped.

Something like flat-headed fish, long centipede-like creatures, and tumor-shaped ones.

Life always manages to grow in the harshest environments and adapt to them.

However, he wasn't going to eat these deep-sea fish.

Because he had just seen the flesh remnants left by an Epoch Disaster, Lu Yuan couldn't shake the feeling that they looked similar, causing goosebumps to rise on his skin.

"Very good! You're willing to offer your most precious food here to your master, showing you're a loyal turtle."

Lu Yuan was very satisfied with its understanding, patting the Giant Crystal Turtle's head: "You eat all these foods yourself."

The Giant Crystal Turtle didn't hold back either, eating them one by one with great enjoyment.

"My mistress and I still have to stay here for a while to copy some useful technological data."

"So during this period, feel free to explore and find some minerals."

"Don't eat minerals in the future, I will give you extraordinary consumables to eat."

The Giant Crystal Turtle's intelligence is not high, but it can sense the joy in its owner's emotions, growling "hoo hoo" with a fierce display.

"What's it saying?"

"It might be expressing that there are good treasures in the deep sea... but it can't retrieve them, so it's inviting you to go together." Miss Conch furrowed her pretty brows, seeming unsure.

"Really?"

"That's probably what it means."

Lu Yuan looked at her, "I'll follow the turtle down. You stay in the space capsule and keep our telepathic link on me, call me if anything happens. I can teleport back instantly."

"Don't worry, quickly go and come back, Old Wolf is here to protect me!"

"Awoo!" Old Wolf licked his nose nervously; in this environment, he dared not come out of the space capsule, fearing he'd freeze to death in less than a minute.

The Greedy Demon God made a "splash" as it followed the Giant Crystal Turtle into the water, involuntarily exclaiming, "So cold."

The ocean surface temperature reached minus 230 degrees Celsius, at which most human instruments could not function properly.

Even more terrifying, there were enormous chaotic flows hidden in the ocean.

One deep-sea whirlpool after another spun rapidly, like black holes.

A 10-meter-tall little giant grabbed onto the Giant Crystal Turtle; the combined weight of these massive creatures was not light, yet they were still swept around by the chaotic flow, having great difficulty moving.

They swam all the way to the seabed, where the Giant Crystal Turtle emitted a faint blue light, enveloping the "Greedy Demon God" as well.

"Whoosh!" It used the Earth Escape Technique, taking Lu Yuan into the oceanic continental shelf.

The feeling was magical, as if they turned into air, swiftly traversing the depths of the earth.

"Earth Escape" is rightfully a top-tier life-saving ability, moving at incredible speed, and Lu Yuan estimated they could move 300 kilometers in an hour.

After traveling for more than two hours, the telepathy with Miss Conch suddenly broke off.

Lu Yuan frowned, realizing it was due to strong extraordinary interference.

The Giant Crystal Turtle stopped, resurfacing from the seabed continental shelf, and howled "Wah wah waaah!"

Unexpectedly, there was air here, as if another grotto heaven!

Lu Yuan's eyes widened, goosebumps rising all over his body.

"Wow, astounding... astounding wealth!!"

He saw a colossal... palace-like structure, about a kilometer wide and four hundred meters high, incredibly massive!

The palace's outer walls were made of crystal clear crystal and coral, covered with a faint glow, with water vapor gently brushing over, lifting strings of small bubbles that floated like pearls around the palace.

The entire structure was enveloped in a hemispherical bubble with air inside.

Moreover, Lu Yuan suspected that this layer of bubble was actually a Different Space.

From the outside, this palace was invisible, only penetrable through the Earth Escape method.

The specifications were astoundingly high, with the palace's roof paved with tens of thousands of glazed tiles, each engraved with exquisite waves and engravings.

Lu Yuan estimated that just these rare-level glazed tiles were worth five thousand Spirit Essence!

On each of the four corners of the roof stood a tall tower, each pinnacle adorned with gilded flying birds, their eye sockets inlaid with Legendary-level Spirit Crystals, emitting dazzling light.

Yes, Legendary-level Spirit Crystals used as decorations!

The thought made his hair stand on end, and Lu Yuan couldn't believe it.

He quickly used the Pioneer's Eye to investigate.

[Failed... this idea is completely wrong...]

[How could this happen...]

[Even just sheltering the Northern Territory alone is extremely difficult.]

[However, turning such a large ship is hard; a wrong decision requires a bigger price to rectify...]

An old voice traversed the overlapping historical mist, echoing in Lu Yuan's ears.

Regret and anger intertwined, eventually evolving into a deep sense of helplessness.

[From now on, the entire Northern Territory will be desolate...]
