Chapter 579: Gold and Bronze Civilization and Forbidden Objects

Just like that, taming a "giant crystal turtle" brought a whole new kind of fun to life.

Traveling is sometimes full of surprises.

When you want to replenish your energy, you find a pile of minerals; when you want to mine, you catch a pet.

This turtle's divine attribute is only 3.0, which makes it a relatively smart type, but it is basically impossible for it to learn human language.

It can be used as a mount, is not afraid of severe cold, has great strength, and can also search for various mineral veins, but it is a little timid and sheds tears easily - those tears can actually be regarded as extraordinary and amazing! Lu Yuan calculated that if one era is calculated as 10,000 years, this guy must devour at least 200,000 spiritual minerals in one era!

If it lived for three epochs, it would have consumed 600,000 spiritual energies.

No wonder it grows so big! "It's all my money." Lu Yuan wailed in his heart. He had never earned so much in his life! However, he did not plan to bring the crystal giant turtle back to Green City.

On the one hand, people would definitely be curious about why the giant crystal turtle was so obedient? How could it tame a strange phenomenon in just one trip? It's not easy to find a reason for this.

However, [Control] is an ability that people are afraid of, and revealing it rashly will cause a lot of trouble.

On the other hand, the giant crystal turtle has other uses.

This turtle has excellent defensive capabilities, and its level 16 extraordinary level can scare off all major civilizations. It also has the ability to escape through earth burrowing, making it the most suitable for carrying the [Temple of Greed]! That's right, he wants to put the [Temple of Greed] on its back! "Let the crystal giant turtle burrow through earth from time to time and appear in various places in the north. It can benefit all races and maintain a sufficient sense of mystery, which is a win-win situation."

…

On this day, Lu Yuan, who was traveling and mining at the same time, finally arrived at the legendary "Northern Ocean".

It was an endless ocean made up of liquid nitrogen and liquid oxygen, with large pieces of dry ice floating on the sea.

The lowest temperature dropped to minus 230 degrees Celsius. This temperature is really too low and most of the air has turned solid.

Only a small amount of noble gases, helium and neon, can remain in gaseous form.

The sky is gray, the sun always stays at the horizon, the weak sunlight cannot penetrate the clouds, and the aurora appears abnormally frequently.

Lu Yuan also found some unmanned detection equipment in the nearby soil, such as drones, hot air balloons, and some bionic puppets, all of which were frozen.

All the parts inside are damaged and have little scientific value.

The previous generations of northern civilization actually tried to explore this vast ocean, but in the end they could only sigh in despair.

Even someone as strong as the Greedy Demon has to activate the "Eternal Fire" for a long time to maintain his body temperature.

The brutal cold can destroy almost everything.

"The atmospheric pressure here is only one thousandth of the normal level, and the oxygen content is also seriously insufficient."

"The current human race is also helpless."

As the air becomes thinner, the buoyancy provided by the atmosphere is greatly reduced, and the anti-gravity system of Pandora's crystal will gradually become ineffective.

If humans want to cross the North, they have to develop spaceship-level engines, put the city in the sky into space, and then transfer it from space to Pangu Continent.

Miss Conch hid in the space capsule and discussed: "Giant engines are not very realistic...If we want to support a city, it is too difficult to use materialistic technology. On the contrary, it is possible to use the idealistic technology of the power of Pangu Continent."

"The North is truly a place blessed by nature. Civilizations outside cannot get in, and those inside cannot leave. Naturally, there are fewer natural disasters."

Only the giant crystal turtle, with its bloody mouth wide open, looked like a fish in water.

It is a natural phenomenon born here.

"Wait for me for a moment."

Lu Yuan didn't want to swim in such a cold deep sea, nor did he want to spend money on flying... The air here was thin, and using "Hurricane" would require more spiritual energy.

So he shrank his body with a "creaking" sound, from a 300-meter giant to a height of 10 meters.

Under the crystal giant turtle's round and puzzled eyes, Lu Yuan carried the space capsule on his back, rode on it without hesitation, and patted its head: "Let's go! What are you daydreaming about?"

The giant crystal turtle swiftly entered the water, flapping its limbs quickly. It was indeed a being that could control the cold. Every time it slid, pieces of black ice would rise up under its feet, making it look like it was sliding on ice flakes.

Two hours later, the sun, which had been hanging on the skyline, finally set.

The sunlight suddenly disappeared and the polar day turned into polar night.

Countless bright stars are hanging in the sky, forming a brilliant Milky Way.

After swimming for about five hours, Lu Yuan saw a small island emitting heat. In this calm ocean of liquid nitrogen, the tall island was particularly conspicuous.

This is an ocean volcano, the only geothermal zone that emits heat within a radius of thousands of miles, and the final destination of their trip.

"Stop right ahead."

The group walked onto the snow-covered island.

The once active volcano is now dead and can no longer erupt any magma.

The geothermal energy, which is more tenacious than weeds, has also shrunk into the interior of the volcano, retaining only the last bit of residual warmth.

The relics left over from the ancient times fluttered in the strong wind. Large, unclear words were written on the torn strips of cloth, floating towards the sky along with the thin air - [Shelter of the Gold and Bronze Civilization], or something like that.

"It turns out that the civilization of those aliens is called the 'Gold and Bronze Civilization'...

Lu Yuan looked around and explored casually, and soon found the gate to the ruins under a glacier.

It was an ancient titanium alloy door, without any rust from time. The dense gear-shaped carvings proved that the civilization was indeed an alien civilization.

There is also a metal monument made of titanium alloy nearby.

The almighty secretary general, Miss Conch, studied it for a long time and translated: [This is a shelter left by the Gold and Bronze Civilization, which contains most of the research data of our civilization.]

[A secret key is required to open the door normally. If you force your way into the door, the internal data will be destroyed. ]

[Please contact the alien left by my civilization to obtain the corresponding key. 】

[If all the remaining aliens of our race die, the ruins will automatically open and all the relics will be given to future generations. No need to thank us, everything is destined by heaven.]

[Please note: some of the encrypted content is taboo and secret, please consider whether to read it. ]

Lu Yuan sighed softly. The aliens' gold and bronze civilization was theoretically only a fourth-level civilization, but it was able to leave behind forbidden secrets. A big reason for this was because this damn place... was too fucking cold.

"The Immortal King should have some mysterious connection with this relic. Once the Immortal King is destroyed, the relic will be opened. Is that what it means?"

"Roar! Roar!" The giant crystal turtle howled at a pile of feces, as if to express that it had once stayed on this island and left its excrement.

"Go play in the sea by yourself, we are going to stay here for a while."

The conch used its ability of "animal affinity" to comfort the giant crystal turtle.

She was wearing a thick space suit and a glass helmet, but even in such bulky clothes, she still looked cute.

"Ah!" The giant crystal turtle happily dived into the water to dig for minerals.

…

Soon, Lu Yuan broke through the thick ice and inserted the magic cube key given to him by the alien into a groove.

With a light "click", the key burst into colorful light and automatically made various complex changes.

About 3 minutes later, the main door of the ruins burst open, revealing a dark interior passage.

However, this passage is only 2.4 meters high, and the Greedy Demon is too huge to fit in at all.

"I will enter in my human body. You wait outside for a while."

"If anything goes wrong, just call the Greedy Devil. I can control it remotely."

Lu Yuan is not afraid of death, but Miss Conch has only one life, and he absolutely cannot die with her.

The girl nodded and returned to the room: "I am connecting to you telepathically, please be careful."

Lu Yuan returned to his human body, put on the heavy space suit, and entered the passage.

The dark corridor depicts the arduous journey of the Golden and Bronze Civilization.

The engraver of the mural had high artistic attainments and carved various marks with ease, making people walk into the ancient and barbaric era.

It was truly a history of hardships and dangers. From the Bronze Age, the head of the giant beast killed by the King of Gold and Bronze himself was hung high at the city gate.

By the Silver Age, the lava rivers in the Forge were flowing continuously, and countless workers created huge cities.

In the Golden Age, the Sky City rose slowly. In the cellar alone, there were three million barrels of wine that could be compared to the nectar of immortality. Drunken guards snored in front of the door of the Glyph Treasury, which contained their carefully crafted legendary masterpieces.

Then came the Diamond Age, when the [Immortal Kings] were created from the depths of the earth, meaning they became a powerful Level 4 civilization.

Finally... is the era of great destruction.

At the end of the mural, one can clearly see a group of gears suspended in the air, with fragments of war sealed in each tooth groove.

The burning city fell into the ocean, and a large number of Giant God Soldiers were entangled and disintegrated by vague objects.

【Long live the Gold and Bronze Civilization! Long live! Long live!】

A row of bright red characters carrying a strong sense of sadness pulled Lu Yuan out of his immersed state.

"It's really... an amazing art." Lu Yuan patted his chest and described the scene he saw in telepathy, "The last line of words contains his blood and life that spurted out."

“This artist did not leave with this civilization, but instead painted here, wanting to leave a mark on history.”

"well……"

"It seems that there won't be too many risks inside." The voice of the conch came, "Because this relic is related to the historical imprint of the Golden Bronze Civilization."

"It's like there are three deaths for humans, among which the death at the historical level is the most important. The Golden Bronze Civilization left these materials so that future generations can remember them."

"So they shouldn't deliberately create some dangerous mechanisms."

"That's true in theory." Lu Yuan sighed softly and continued walking forward.

Soon he came to a bronze door. It was a complex combination lock that required various carvings to decipher. Perhaps it was to test the carving skills of the entrants?

However, for the grand master craftsman, these things were as simple as elementary school mathematics. In less than two minutes, Lu Yuan had deciphered the password.

The door slammed open, dust flew up, and the shadow of time was raised.

Lu Yuan's pupils contracted.

Inside were… various “Giant Soldiers” holding tools, filling the entire playground.

At first glance, it might look like there are as many as 10,000 of them!

These guys have different functions. Some hold hammers and drills, which are tool-types; some hold rune rifles and cannons; and some even hold cold weapons and shields.

This silent army, spanning an era, still exudes a shocking power, as if reminding future generations to remember our existence beneath the dust of history.

There is also a spherical device at the front with a diameter of 5 meters, which should be the central host that controls these giant soldiers.

“This is a huge fortune.”

"What a pity. It's of no use to me. Leave it to humans and dwarves."

Lu Yuan did not touch these robots rashly and walked inside.

In the next room, there are computer cases and bookcases that are more than 2 meters high.

Lu Yuan randomly picked up a book and flipped through it for a while. There were various cartoon pictures on it. It might be a fairy tale book about the "Golden Bronze Civilization".

[“Mom, mom, the sun is rising!” The little dwarf rabbit jumped to his mother, his furry ears trembling. ]

There is no mistake in the poem, post, content, and read the book on 6, 9, and bar!

[Mother Rabbit was sorting the carrots in the storage room. When she heard Huihui's voice, she turned around with a smile and said, "Then we have to go pick mushrooms quickly."]

【……】

Lu Yuan actually couldn’t quite understand the words, so he guessed a story based on the pictures.

A faint sadness rises from my heart.

A declining civilization is struggling and working hard to preserve its culture with all its might.

It's like a drowning person who tries his best to come out of the water, but what he shouts is not "Help", but his own name, wanting others to remember him.

However, how many scholars of later civilizations are willing to truly understand them? Most of the remains of civilizations have even had their walls stripped away, turning them into materials for carvings.

All the famous scenic spots and historical anecdotes have turned to ashes.

"The only one who can remember yourself is yourself..."

Lu Yuan read for a while and then put the book down.

He looked at the case made of black iron and titanium alloy.

One of the computer cases might contain the idealistic technology of the fourth-level civilization, but it is still of little use to Lu Yuan.

Level 4 technology generally requires a lot of heavy industry support, which is a completely different path from the way of craftsmanship.

"It's a bargain for humans. When they have the ability, they can get it later."

Contrary to his expectations, he did not find the treasure house.

Perhaps because the situation was so urgent at the time, the Golden Bronze Civilization only left these few things...

After searching for a long time, Lu Yuan finally found a single room, but this door was so exquisite that it was actually a legendary extraordinary item! [The door of fine gold, legendary level. ]

[A large amount of refined gold material is used to isolate the door from physical detection and idealistic detection. 】

There is no mechanical lock.

On the metal plate near the gate, there is a line of complex text.

Lu Yuan took out a monitoring device and sent the images back.

Miss Conch translated: [It contains forbidden information. A large amount of acidic liquid is needed to open the door, which will take several years to corrode.]

[Be careful when opening this door. The more you know, the more dangerous it is. ]

In other words, this civilization simply welded the door shut, and one must think twice before opening it.

However, this matter did not pose a problem for Lu Yuan. He took a deep breath and knocked a few times.

He then used the Eternal Fire to drill into the gap and felt the thickness of the door.

"About 22 centimeters thick."

Then, with a light "whoosh" sound, he teleported over.

A small dark room greeted me.

With the blessing of the eternal fire in his body, the room was illuminated by a red light.

“Huh… this is…”

Lu Yuan's eyes widened, his heart suddenly sank, and he saw a crystal coffin.

There was a piece of dark red flesh inside, giving off a forbidden and ominous aura. The strange feeling was even colder than the sea of ​​liquid nitrogen outside.

At this moment, he felt fear for the first time in a long time.

This is the fear of an unknown fate.

Hidden ahead is the secret that he has been pursuing for a long, long time...

He was afraid that he would never be able to defeat this opponent.

Worrying that everything is in vain; worrying that humans will suffer the same fate...

So at this moment, all kinds of complex emotions surged out, causing my mind to suddenly "buzz".

"Don't be nervous..." Fortunately, he was also a seasoned warrior. He bit the tip of his tongue hard, and the spicy taste calmed him down a little.

This strange piece of dark red flesh and blood still has vitality after so many years.

It kept wriggling, and its countless blood vessels extended outward like the tentacles of a snail.

The various inscriptions on the crystal coffin are densely packed and as tiny as ants crawling around.

"What is that thing? It doesn't look like the flesh of a ghost... some forbidden product?" Lu Yuan was also a skilled and courageous man. After calming down, he gritted his teeth and peeked for a while.

He tried to call the conch to report that he was safe, but found that both his telepathy and the monitoring equipment in his hands were blocked by the legendary gate.

So he could only ponder it carefully through a crystal coffin, and at the same time took out several instruments to make measurements.

"The idealistic energy density of this piece of meat is not high, but its vitality is very strong. It looks a bit like... Tai Sui?"

"If we bomb it into minced meat, there might be no way to restore it like a ghost... I don't feel any abnormal idealistic rules."

"What do you mean? What does the Gold and Bronze Civilization want to tell me? Is this the flesh of the old monsters from the First Era? Slightly weaker than [ghosts], but intelligent?"

Lu Yuan was vaguely confused and imagined an enemy in his mind.

The First Age must have some great secrets. Since some of the "myths" turned into irrational "ghosts", perhaps other myths turned into other things.

For example, a rational [ghost]! That is obviously more terrifying than a [ghost] and almost impossible to defeat.

But the strength of this piece of meat was far from as strong as he imagined...

It wasn't that he was getting carried away. As a veteran soldier, he still had some judgment. The instrument in his hand also proved this.

"Hmm? Is this a picture engraved with glyphs?"

Lu Yuan observed the mysterious patterns in the crystal coffin: many strange things appeared on the earth and in the starry sky, in the shapes of centipedes, Tai Sui, and various irregular tumors, which looked like tumors in the late stage of cancer.

But a large group of species were scrambling for these things - Lu Yuan narrowed his eyes. The picture was a bit abstract, which made him vaguely suspicious.

The floating cities in the sky were firing at each other and even began to annihilate the major races on the ground.

Behind the sky, there is a vague giant hidden...

Chaos, weirdness, panic.

The tragic scene at the end of the era unfolded before Lu Yuan's eyes.

…

Something even weirder happened! As if it had sensed his gaze, the wriggling piece of flesh and blood actually crawled towards Lu Yuan like a snail! For some reason, although this thing was not strong and did not crawl very fast, it made Lu Yuan inexplicably terrified, just like a sheep encountering a tiger. He was so frightened that he broke out in a cold sweat.

Murmuring whispers came to my mind.

It seems like there is a powerful existence in the dark that is looking for me.

"Oh no, I know too much this time." Lu Yuan gritted his teeth and used [Alternative Space] to protect himself.

Then, at the moment when the piece of meat touched a certain carving!

A light blue flame suddenly appeared in the crystal coffin! The flame was extremely hot, and it exploded with a temperature of tens of thousands of degrees in an instant! "Boom!"

In just one second, the fist-sized piece of flesh and blood was burned into charcoal and turned into the most basic ash.

Nothing happened during this period, which also confirmed that Lu Yuan's judgment was correct - the strength of this thing was indeed not high.

And the picture engraved with inscriptions was also completely burned and no longer existed.

"What's going on?"

"This should be a deliberate trap... to prevent me from completely triggering some dangerous taboo information."

Lu Yuan swallowed and the air fell calm.

But he didn't dare to cancel the alien space, and racked his brains to think: "The strength of an object is not too high, but it can destroy an era of Pangu Continent... What are those cancer cell-like objects?"

"And where did the forbidden information come from? Why would the [ghost] come after me after I violated the forbidden information?"

Looking around, I found that there was nothing around and there were no more paintings on the walls.

This heap of burnt ashes was the only thing in the entire little room.

There is no one to discuss with, so I can only think for myself.

"The Gold and Bronze Civilization must have deliberately destroyed this mass of flesh and blood to show it to me. Just to show that this enemy may be ubiquitous, and it is not a [ghost] that destroyed the world."
