"Supernatural Machine City (

Without any delay, the group did not care to pack the spoils in the city, and then followed the assassin to the smelting plant further underground.

After leaving, Ren and the others were immediately stunned by the sight in front of them!

I thought that the smelting plant in ancient history should be a backward scene of earthen stoves, boilers, and anvils.

Unexpectedly, there was a highly mechanized smelter in front of him.

Even...more than modern steel mills.

There is a wide range of equipment that is not inferior to modern steelmaking plants, such as large steelmaking furnaces, refining furnaces, hot metal tanks, internal combustion boilers, fuel conveyor belts... and complete ventilation ducts and smoke removal equipment. There are also special reaction devices constructed of brass and rivets that are incomprehensible.

No one thought that the Goblin civilization had already owned such an advanced large steelmaking plant countless years ago. The collision of ancient "alchemy" and "engineering" created such a smelting plant with the characteristics of goblin civilization underground.

If the steel mills of Modern Machinery City are in the dark punk style, then this is the alchemy magic style.

This goblin civilization, on another branch of the science and technology tree, has already been luxuriant.

......

The laymen like Rennes also look at their appearance.

Only a professional mechanic can understand the internal structure and operation of these equipment.

At this look, Father Tuster was shocked again.

"This...this sword is incredible! The smelting equipment is still so well preserved. These designs...it's amazing!"

While exclaiming, he carefully stroked the mechanical equipment with his hands, as if touching the skin of a peerless stunner, his eyes full of heat.

It's probably because I haven't expressed the emotion of "shock" in the past 30 years, and let him release it today.

Goblins are inherently small, and their buildings are very small.

But the scale of this smelter is surprisingly large.

Rehn intuitively walked into the factory area, thinking that he had walked into a steel forest, he was like a blueprint passing by under a big tree. Surrounded by giant iron bumps, people have a kind of awe from the bottom of their hearts. The awe of technology, the awe of alchemy, the awe of a civilization.

How exaggerated the smelting technology of this goblin civilization is!

Ren couldn't understand technology, but his eyes could understand other things.

When he swept his gaze, he saw the "iron ingots" piled up in the open space of the smelter!

These dark iron knots are familiar. Renn took it in his hand and tried it. The starting point was heavy. A piece of about seven or eight hundred catties, but it was half the weight of the same volume of steel. It's cold, and it feels exactly the same as the shield touched before!

Ren wasn't quite sure, and asked the professionals on the side, "Grandpa Tuster, this seems to be the material for forging a shield!"

As soon as Tuster heard it, he picked up a few pieces with his robotic arm and looked at it, and immediately confirmed: "This is all [Angela Black Iron]!"

"Really are?!"

With that said, Renn instantly felt that the black iron ingots in front of him, just like the golden mountains in a warehouse, suddenly shone in gold!

At first glance, there are thousands of cubic meters here!

It can be said that before the mine was discovered, just a little iron **** dropped from the ground of the smelter, it can become a hot commodity on the black market.

No one thought that there would be such an exaggerated amount of "God's Blood Mine"!

This goblin civilization is a treasure everywhere for mechanics. It's like a hamster fell into a warehouse full of nuts, and his eyes glowed everywhere.

Tuste was really pleasantly surprised today. He said: "Just this pile of smelted products is enough for the first stage of the construction of our mechanical cost airship!"

After a pause, the old man looked at the end of the smelting plant again, and said, "Go, let's continue to see! There must be an ore warehouse and a forging plant in front of us, maybe it will give us more surprises!"

.......

Sure enough, there is also an ore warehouse.

Pile up a lot of high-purity "God's Blood Mine"!

Then, in that forging factory, there are indeed a large number of large finished shields, and some metal objects such as armors, axes, scimitars... These are all standard equipment that goblin engineers have built for their army!

Of course, the most important thing is not these finished and semi-finished products, but the advanced forging equipment in the "forging plant".

This even let Rennes see the feeling of semi-automatic mechanized assembly line in the past life!

Furnace, mold, mechanical forging hammer, quenching...the whole process of forging has specialized mechanical equipment.

This allows the goblins to mass-produce various standard equipment without much manpower.

"No wonder I always feel that the traces of the shields are a little strange... It turns out that they are not forged by humans!"

Tuster, a professional mechanic, was also surprised.

The forging machinery of this era cannot achieve high precision at all, and can at most complete the preliminary melting and forging process. The more sophisticated equipment must be hammered by hand.

But now I didn't expect that a forging workshop countless years ago would have such advanced mechanical forging equipment. Moreover, the quality of mechanically forged equipment is no worse than that of hand-forged "excellent grade"!

But the manpower and material resources consumed by the two are not at the same level at all.

The group originally wanted to go deeper, but invariably stopped in the forging workshop.

The equipment here really made everyone look at it.

Tuster took a look at the forging equipment, which was fairly well preserved, and suggested: "I think we can directly move a part of the forging factory of the Machine City into this mine. It will save much time. The trouble of transporting ore. Moreover, the equipment here seems to be intact, at least the boilers should be able to be used...the mine tunnel, exhaust system, cooling pool are all ready. This is better than our new large-scale refinery. The steel mill has to save too much time."

Hearing this, Ryan pondered for a moment and agreed with the old man's statement: "I think it is feasible. This mine is underground, and it will hardly be affected by monsters. Even if it is a tide of corpses, the mine layer is several kilometers deep underground and has been isolated. With most of the smell...this place can be built into our secret base in Black Dragon City."

Both Ren and the professionals said so, and Yumir naturally had no opinion.

However, this is not the time to discuss this matter in detail.

Because... Captain Rhine and the others once again sent people to urge them to see that "still usable" ancient machine!

......

Rehn walked through the forging factory, and then he saw another black technology-elevator!

Although it is rough, it looks no different from the elevators on the construction sites in Wren's previous life.

This "goblin elevator" has a console, and Ren can understand the words "up", "down" and "pause". It seems that there is a special energy drive method that replaces the power supply. But the equipment has broken down, or it has no energy, and it has completely lost its function.

Fortunately, the people who came down before have figured out its manual method and checked it. The structure is still stable and firm.

Then there was a burst of hand-cranked operation, and the cage of the elevator slowly descended.

The surrounding temperature is getting lower and lower, as if from an ice storehouse, and the cold is piercing.

Fortunately, everyone is extraordinary, and this temperature change has no effect.

After a while, the elevator descended to a depth of about one kilometer and stopped.

And this is a closed space, surrounded by thick metal walls, like a closed laboratory.

As soon as I came in, the system heard a tone.

【caveat! The absorption of "Abyss Demon Qi" has exceeded the host's tolerance, please pay attention...]

Ren looked at the system panel in his heart and raised his brow slightly.

Because, the data panel shows that the concentration of "Abyss Demon Qi" in this laboratory has reached twenty times that of the ground!

Ren has [Thunder Totem], which is automatically absorbing and transforming vindictive energy all the time. Even if the devilish energy here has already surpassed the limit that the body can bear, it can be converted. Here, the increase in his fighting energy is seven or eight times that of the ground!

"Cultivation Holy Land..."

His eyes lit up, and there was such emotion in his heart.

Such a rich environment is estimated to be "toxin deadly" for others, but for him with the [God Healing Technique], it is completely acceptable!

Of course, this is not the most shocking part of this laboratory.

The most shocking thing was the piece of black crystal that almost flashed blind in front of me!

As soon as the magic light source was measured, the entire black crystal that slowly entered the eye was crystal clear, reflecting the bright light.

This is a crystal mine?

Obviously not!

The crystals were moved here and cut into a specific diamond-shaped block. And taking a closer look, those crystals are still engraved with mysterious alchemy formations.

There seems to be some tricky skeletons in the laboratory, but the people who came down first have beaten them into white skeletons.

Tuster looked at the black crystals, and then at the working instrument, and immediately understood what he was surprised to say: "The goblins used to be man-made'magic crystals'?!"

"Man-made magic crystal?"

Ren was also stunned. The magic crystal is the kind of energy crystal in the living corpse. Can that thing be made artificially?

He took a piece and put it in his hand, it was exactly the same as the magic crystal that killed the living corpse outside.

However, the amount of "Abyss Demon Qi" contained in this brick-sized magic crystal is a hundred times that of a general fifth-order magic crystal!

What is this thing for?

Practice?

Or... is it energy?

Faintly, Renne thought he had guessed something.

......

At this time, Tuster had already walked over and looked at the machine that was still in operation, filling the crystal with black energy.

The old man pondered for a while, and said with emotion: "It's a genius design... They actually transformed the energy of the'Abyss Demon Qi' to provide real-time energy to the alchemy formation so that it can continue to operate until now..."

Renn's gaze also followed the machine. Except for those shining alchemy arrays that couldn't understand, the overall structure of the instrument was not complicated.

A ten-meter-high cylindrical tank (probably brass), an intermediate machine with a few buttons, then the connecting pipes, and finally the cabin for the manufacture of "artificial magic crystals".

"Huh... not right!"

Moreover, after confirming that this was "Abyss Demon Qi", Renn instantly thought of another very critical question.

Didn't the "Abyss Demon Qi" burst out after the [Kuroshio]? The presence of this instrument means that these goblins have already started using this gas countless years ago.

What is this situation? "

"Also... Didn't the legend of "Abyss Demon Qi" come from hell? How could this thing be picked up from a iron pass?"

In addition to looking shocked, Renne was also full of question marks.

He had seen the "Abyss Demon Qi" gushing out of the "Eye of Hell" in the Coleman Atrium Tribe before, and Marfa also said that it was a hole connecting hell.

But now?

That weird big iron bucket was framed by steel shelves, and it didn't touch the ground at all!

This means that the "Abyss Demon Qi" here does not come from the ground at all, but from the jar!

......

At this moment ~lightnovelpub.net~ Renn suddenly understood that the so-called "Abyss Demon Qi" might have been misunderstood by them.

"What exactly is in the tank? An energy generating device similar to a'nuclear reactor'? Or is it really like a biogas digester, with something fermented like papa?"

Rennes thought of the "biogas digester" for the first time.

A lot of technology looks very high-end, isn't it just the design of a biogas digester?

A pot was connected to a trachea, and then injected into the crystals carved with magic patterns, creating a large number of "artificial magic crystals."

But now it is determined that the "Abyss Demon Qi" is not a gas from hell, but may have been created by certain conditions.

Then another problem has arisen.

Now the entire area west of the Alcron Mountains has erupted [Kuroshio], and a large amount of "Abyss Demon Qi" spurted up from the ground, and it continued to spew continuously.

But obviously, there would definitely not be such an iron bucket under such a vast land, or some goblin black technology operating.

The most likely thing is that the "thing" that emits black energy is not a device that requires external conditions to intervene like a nuclear reactor, but it is a natural substance that can continuously release "Abyss Demon Qi".

And the "things" in this iron bucket should have the same source as the "things" buried underground!

What is in the iron barrel that will keep it going for countless years and still swell the magic energy?

And the black gas that gushes from under the "Eye of Hell" has covered the entire wasteland. Is there a lot of underground, or is it very large... the entire wasteland is that kind of "thing"?

At this moment, Ren suddenly realized that the contents of this iron pot might hide a prehistoric secret.

This secret may explain the origin of the fog in this ice ridge wasteland...
