Heng Yi waited for a long time, but he didn't hear Elder Qing's voice again, he thought, maybe the elder couldn't hear it.

Entering the metal building, the rhythmic sound of 'bang, bang, bang......' heard outside at first could not be found, and Heng Yi guessed that it might be the sound of broken metal being blown and colliding by the wind somewhere, and when he came in, the wind became smaller, and it was gone.

I passed through a metal door of the Yongdao again, and in front of me, it was still a corridor, but the scene inside was very different from just now.

In the corridor, the floor is full of metal parts of different shapes, large and small.

Heng Yi walked among the metal parts in one place and found that most of them had traces of being melted by energy.

Heng Yifei looked down, and some of the parts vaguely resembled the shape of the front half of a metal boot.

'Is it the giant's armor?'

Heng Yi guessed wildly, except for Wang Buyi and Xu Wenfeng, he had never seen other Divine Gate battle armors, but even Xu Wenfeng's battle armor was not so huge and thick.

Heng Yi searched for the scattered metal parts, but he couldn't see what they were, most of them were melted and deformed by energy.

"There should still be one inside, it looks like it was destroyed by the attackers...... ' Heng Yi left this section of the road and continued to fly inside.

In this way, it flew all the way for two hours, twisting and turning, and the roads were full of wreckage of metal parts all over the ground, judging from the many roughly intact parts and the comparative situation, Heng Yi felt that how these parts were combined should be a full-covered metal armor with a height of about ten to ninety zhang.

"Strange, I said it. The giant clan in the universe is very backward and has long perished, and at the time of its demise, the main star of the giant clan will not be able to make weapons, relying on its innate natural power......"

The more metal parts he saw, the deeper his suspicions became.

He suddenly realized that he didn't see any parts of the weapon.

It's a strange thing, if it's a Warframe, there's no reason to have no weapons.

In contrast, weapons should be less damaged than armor -

Heng Yi has the heart to find it. It was found that most of the metal parts in the corridor had a cylindrical metal in the scattered area of an overall battle armor.

It looks like the handle of a weapon, but is it only the handle? That's obviously weird.

Heng Yi couldn't think of a reason, so he could only continue to fly into the depths.

After flying for another three hours, the corridor began to narrow, and its diameter was only ten zhang wide.

Under the light of the illumination talisman. After seeing the narrowed corridor, I found that the situation had changed a lot.

Along the way, all Hengyi has seen are scattered along the road, and many even piled up seriously damaged metal parts.

And narrowed in the corridor. The metal parts are much smaller. However, it's basically complete!

If not for being 'dismembered'.

Falling all over the ground, they are all giants!

But unlike Heng Yi's guess, it's not the giant clan, it's a huge metal man!

They are all the same body shape, roughly in human form. The body is one zhang long, and many of them are still sitting on the head of an all-metal thing that is thirty zhang long and ten zhang wide, like a giant centipede, and the centipede-shaped metal back is obviously a container carrying things.

Heng Yi looked at it. There are a lot of metal plates, metal parts. It's all the ones you see outside, as if they were unfinished products that need to be assembled.

The heads of these metal centipedes were cut off, and the bodies sitting on them were one long, and the heads of the metal people with completely human body structure were also separated from the body.

"Could it be the Iron Man Galaxy mentioned in the General History of Mankind, the Iron Civilization?" Heng Yi remembered that the General History of Mankind mentioned that tens of thousands of years ago the universe had the second largest number of galaxies in the universe, and its strength was comparable to that of the Sind civilization. Because there are not many descriptions of the Iron Man Galaxy in the records of the General History, only approximately, at this moment, Heng Yi saw the form of these metal men, and he felt that it should be.

After the demise of the Iron Man Galaxy, human civilization and Sind civilization have been researched in many ways, and the conjecture conclusion is that the Iron Man Galaxy was once a human-like civilization as the origin, but after entering the age of science and technology, the intelligent machines created were beyond human control, so unfortunately they were exterminated by the machines in turn, because human beings should not logically exist in the concept of machines - pests!

Intelligent machines are cold and ruthless, and they will obliterate the emotional factor, and they are created as a kind of production tool, and the meaning is to maximize production, utilization, and efficiency. And all of this is contrary to the common practices of the founder's human beings.

When machines have an evolutionary intelligence consciousness and break away from the rules of human beings that regard humans as the main thing, they will come to a result in logical judgments that the existence of human beings hinders and wastes the production of machines, and many things produced by machines have no value at all and are a waste of resources.

Under the dominance of such machines, it is not surprising that the humans who created them will be exterminated.

The core of the Iron Man machine, which is called the mastermind of the iron civilization by human civilization.

The main brain is constantly developing and evolving, constantly enriching itself through countless robot cognition, analyzing data, and developing technology.

Without the master of the human-like civilization that created them, building more machines, changing the planet, and plundering more resources have become the guidelines for the steel civilization to rush to the universe.

One galaxy after another has been invaded by the steel civilization, and all the living things on the planet they invaded have been wiped out, leaving no exception, for the steel civilization, non-robots are all wasted resources, and those who have no development, exploration, manufacturing, and combat capabilities in the robots are also waste products and must be rebuilt.

The steel civilization is the most terrible civilization in the history of the universe, and all the resources useful to them in the invaded planets are hollowed out, and then the cold steel planets are built, and the invaded planets and galaxies are almost destroyed.

In the general history of human civilization, the iron civilization is called the most terrible destroyer of the universe.

However, Heng Yi remembers that it was said in the general history that the iron civilization was destroyed by the human leaders, and all the main star splits of the galaxy were destroyed by the four leaders of the dream gods. The main brain of the steel civilization was destroyed by the legend of justice in the dream god Yiyun, and the steel civilization was paralyzed after the main brain and the split brain were destroyed, and all the steel galaxies made were recycled by human civilization, and later because of the emergence of the Sind civilization, it became two civilizations that continued to share resources, and the recycling lasted for 20,000 years.

If this was the artificial steel star of the Iron Civilization, it should have been recycled long ago, if not. And where is this place?' Heng Yi became more and more puzzled, it is said in the general history of mankind that it is completely recycled.

It is impossible for the two major civilizations of mankind and Sinde to put the metal resources of the steel civilization without recycling!

Heng Yi took a deep breath and used Professor Hong's strength to unleash the flying slash into a swift sword, slashing at the body of a robot!

Mars Splash -

The blade of the Providence sword was deformed, and the metal man's chest was only left with a half-inch-deep scar.

Bursts of red energy light mist converged on the damaged part of the Heavenly Providence blade, and in a moment, the blade repaired itself as before.

This is the ability of magic weapons above the star level. The ability of the Soul One Artifact is even more powerful, and it has the nickname of never disappearing.

Heng Yi observed the wound on the metal man's chest and marveled.

"The dream god is amazing. Easily chop off the heads of these metal men. The head of a centipede of that size was cut off. Tens of thousands of years ago, their strength seemed to be at least equivalent to the strength of the current Star Venerable, and possibly the strength of the Star Venerable, I really don't know how strong they are now. Heng Yi was not only not depressed, but very excited, and this stark contrast made him know that his cultivation still had a long way to go, and there was still a lot of room for improvement.

Heng Yi continued to fly forward, he was already full of curiosity about this place. In the end, is this an iron star left over from the steel civilization?

If so, why hasn't it been recycled so far?

Are there any more traces of the Dream God who once fought here?

In the much narrower corridor, Heng Yi flew away for another hour, and the vision finally became completely different.

It seems that this is the center of the planet, and the area surrounded by metal walls in all directions is thousands of feet wide and high. It's impossible to know what it was like.

Because in the huge space, there are ruins everywhere. The large and small metal fragments that could not be seen in full shape at all showed signs of severe energy melting.

Heng Yi is one head and two big, this is simply a huge metal garbage dump, and it is probably easier to rummage through everything in it than to find a needle in a haystack.

Heng Yi took out the Dao talisman that Zhang had obtained before his experience from the storage talisman and specifically explored the energy of the magic weapon.

Infused with true qi, the Dao talisman turned into a ball of colored light, and the light reached a thousand feet!

Heng Yi urged one at a distance, and it didn't take long for the colored light to completely cover the garbage dump of thousands of zhang.

This is purely a fluke method, if there are metal parts with electricity in it, the Dao Charm will be able to react to the energy, but from the scene of the garbage dump in front of you, it is difficult to hope.

Heng Yi looked around, and saw that there were huge broken round holes on the metal walls, but they were full of metal burned by energy, it seemed that it used to be a channel to transport things out, but it had long been blocked, and if he wanted to clean it up, it was simply a fantasy with his own strength, and with the time when Heng Yi flew away, he could be sure that the metal garbage in any round hole channel could fill the square garbage dump he was in.

Unless there are enough storage talismans to put all the garbage in it, it is okay, but I don't know how much it will cost, anyway, the storage talisman on Hengyi's body is not even a fraction of it, so I don't have to think about it.

Heng Yi looked down at the ground and didn't know how high the garbage pile was, in fact, he didn't have any expectations for the Dao Talisman to explore energy, and it was difficult to leave something intact with this level of destruction.

If there were, with the tens of thousands of years of history here, the energy would have been exhausted long ago.

There is too much metal garbage here, and the metal itself has trouble exploring the Dao Talisman, Heng Yi knew that there would be no results for a while, so he flew along the metal wall at will, knocking and knocking, trying to find out if there was a hole behind the metal wall.

Suddenly, the metal wall that Heng Yi knocked on at will made an abnormal sound.

Heng Yi hovered in mid-air in surprise, and when he turned his head to look, the knock of the metal wall suddenly opened a palm-sized piece!
