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, zigzag and turned, and the roads were full of the remains 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.

"It's strange, Zizi said that the giant clan in the universe is very backward, and it has long perished, and when it perished, the main star of the giant clan did not know how to make weapons, and it relied on its innate natural power to ......"

The more metal parts you see. Heng Yi's suspicions deepened.

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 comparison, the damage of weapons should be lower than that of Warframes-

Heng Yi searched for it and found that most of the metal parts in the corridor were cylindrical in the scattered area of the entire 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. You can 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 road symbol, I saw the narrowed corridor clearly, and found that the situation had changed a lot.

All the way so far, what Heng Yi has seen is scattered on the road. A lot even piled up badly broken metal parts.

In the narrowed corridor, the metal parts are much smaller. But. 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 were all the same, about human, and a foot long. Many of them were also sitting on the heads of all-metal things that were 30 zhang long and 10 zhang wide, like giant centipedes, and the centipede-shaped metal backs were obviously containers carrying things.

Heng Yi looked at it. There are many metal plates and metal parts inside, which are the ones seen from the outside, as if they are 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 era of science and technology, the intelligent machines created were beyond human control, so unfortunately they were extinct by machines, 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 techniques.

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 steel 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 god, and the master brain of the steel civilization was destroyed by the righteous legend in the dream god. The two civilizations continued to share resources, and recycling lasted for a full 20,000 years.

'If this is the artificial steel star of the steel civilization, it should have been recycled long ago, if not, then 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 splashed –

The blade of Providence is deformed. The metal man's chest was only half an inch deep.

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, and the ability of the soul integration magic weapon is even more powerful, and it has the nickname of never disappearing.

Heng Yi observes the wound on the metal man's chest. Amazed.

"The Dream God is so powerful, it can easily chop off the heads of these metal people. 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 has a long way to go, and there is still a lot of room for improvement.

Heng Yi continued to fly forward, he was already curious about this place, in the end. Is this an iron star left over from the Iron Civilization?

If so, why hasn't it been recycled?

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. I don't know what it used to be like.

Because in the huge space, there are broken metal fragments everywhere, and the complete shape cannot be seen at all, all of which have traces of serious melting by energy.

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 round holes in the metal walls, but they were full of metal that had been incinerated by energy, it seemed that it used to be a channel to transport things out of the hall, but it had already been blocked, and if he wanted to clean it up, it was 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 you don't have to think about it.

Heng Yi looked down at the ground and didn't know how high the garbage heap had piled up, but 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 the Dao would not have results for a while, so he flew along the metal wall at will, knocking and knocking, wanting 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 hammer of the metal wall suddenly opened a palm-sized piece! (To be continued......
