"I don't understand this either. Theoretically, the temperature you just emitted cannot melt it... In fact, you didn't really melt it just now. The characteristic of this metal is that as long as it does not reach the maximum temperature it can withstand,

, it can return to its original appearance. The fact that it was able to recover quickly just now means that you just deformed it, not really melted it... Hey, why don't you try it on? This exoskeleton mecha can strengthen your strength. If

The strength of an ordinary person is two hundred kilograms. After strengthening it, it will be at least two thousand kilograms or even more. It may be of some use to you." Bing Ling said with excitement.

"Haha, I am a person with super powers. This thing has no meaning to a person with super powers." Zhou Sen laughed and said unconcernedly.

"Zhou Sen, you are wrong! The universe is a magical world, and there are many things that you and I cannot understand. At least, you cannot understand why we awakened humans can compete with gods. In fact, we have done it. This intelligence

Memory metal is called soul metal by us awakened humans. Only awakened warriors from high planes can possess a little bit. That so-called little bit, maybe as big as a fingernail, can bring out the power of a mecha or even a spaceship.

It has been strengthened several times, and it is impossible to even think about a luxurious exoskeleton mecha made of pure soul metal like this. Its terrifying power can be imagined!" Bing Ling's expression was extremely serious.

"I'll give it a try." Zhou Sen saw Bing Ling's serious face and didn't want to reject her kindness, "But how do I wear it?"

"Just remove the surrounding fixed brackets and stand in the middle of the exoskeleton mecha."

"oh……"

Zhou Sen nodded, directly used the inextinguishable fire essence to melt the fixed bracket of the exoskeleton mecha, and then walked straight in from the side.

A strange scene appeared.

The jet-black mecha that was originally a head taller than Zhou Sen began to shrink and stuck tightly to Zhou Sen's body. It was just the right size, and some of the joints were perfect.

"Does this thing have the optical brain on your spaceship?" Zhou Sen looked at the super jet black metal clinging to his body in surprise.

"No, this is the magical thing about soul metal. It has extremely high intelligence. It can absorb your brain waves, and then analyze your needs and purposes through the intelligence of the metal. Of course, this ability can only

Only pure soul metal can be possessed. Like us awakened humans, we usually smelt soul metal as an alloy to strengthen the ability of some key parts of the spacecraft. It only has a certain self-healing function, but it cannot be said to have intelligence."

"There is such a magical metal!" Zhou Sen exclaimed.

"Actually, I have always believed that it is not a real metal. It should be a mysterious species, but it only exists in the form of metal." Bing Ling said.

"It makes sense! If it is really a lifeless metal, it will definitely not be able to understand human thoughts, let alone analyze brain waves... I will try its power..."

As Zhou Sen spoke, he walked up to a huge metal pillar. The two of them hugged this metal pillar. It was somewhat similar to the Roman pillars on Earth. It was for decoration and did not bear any weight.

After walking in front of the metal pillar, Zhou Sen stood up and did not activate his superpower. Instead, he used the strength of his limbs to punch the metal pillar lightly.

Speaking of a light blow, it is only for Zhou Sen's strength. After all, if Zhou Sen's "Invincible Secret Book" is used with all his strength, not to mention this metal pillar, even the entire shopping mall will be wiped out.

In fact, this punch was not light, it was at least equivalent to the strength of five ordinary people.

The strength of five ordinary people must reach at least 500 kilograms.

According to Zhou Sen's opinion, this kind of power is simply negligible when faced with the metal pillar held by the two people.

"call"

The howling wind blew through the quiet shopping mall.

"Boom!"

A slight crash sounded in the quiet shopping mall.

"ah……"

Zhou Sen was petrified, with an incredible expression in his eyes. At the same time, Bing Ling, who was watching, was also stunned.

At this time, Zhou Sen's fist, like a knife cutting tofu, completely sunk into the metal pillar, and even half of his arm entered the metal pillar.

Zhou Sen began to expect that the exoskeleton mecha made of soul metal should be able to knock down the metal pillar, but he never dreamed that it could penetrate directly. Obviously, the soul metal not only enhanced his strength, but also

Enhanced his speed.

"Is it a problem with this pillar..."

Zhou Sen suspected that the metal pillar was too fragile. However, he refined it with the Inextinguishable Fire Essence and immediately discovered that the metal pillar was also made of alloy. Although the material could not be compared with the metal of those cold weapons, it was better than some cold weapons on the earth.

I don’t know how many times stronger the material is.

Facing such a strong metal pillar, not to mention this light punch, even if Zhou Sen used the "Invincible Secret Book", he could only knock the metal pillar away, but he could not sink into it as easily as he did now.

"What a powerful force!"

Zhou Sen, who woke up, couldn't help but gasped. He repeatedly checked the structure of the exoskeleton mecha, and even searched with his spiritual consciousness, but found nothing. He even didn't find the power of the exoskeleton mecha.

device.

The entire exoskeleton metal mecha is integrated, like a hollow black metal frame. If Bing Ling had not said it, he would not have been able to imagine the relationship between this hollow metal frame and a mecha full of science fiction.

"Where is the power device of this exoskeleton mecha?" Zhou Sen couldn't help but ask.

"Haha, this is the magic of soul metal. It doesn't need power at all to achieve the strongest mechanical effect." Bing Ling said with a smile: "The only flaw in this exoskeleton mecha is that the industrial design is too poor.

, if it were smelted at the industrial level of our awakened humanity, it would definitely not look like this... Hey, I almost forgot, didn't you melt it just now? If you don't like the way it looks now, otherwise, yourself

Design it from the ground up? Oh... No way, you can only make it temporarily in a liquid state, but you can't completely change it..."

"This is actually quite good." Zhou Sen shook his head. Although he felt that the shape of this exoskeleton mecha was a bit weird, it was extremely comfortable to wear and it was extremely ergonomic.

It can be melted and collected into the Qiankun Ring at any time. When used, it can be directly summoned and put on without the hassle of putting it on and taking off. It is very convenient and does not need to be refined at all.

Of course, the main reason is that Zhou Sen is afraid of damaging the internal structure of the soul metal. If he randomly refines it with the inextinguishable fire spirit and scraps this rare metal, it will be a big loss.

Now, what Zhou Sen wants to do most is to find a place to test how much power this mecha can unleash. Immediately, Zhou Sen broke this idea.

This planet is extremely desolate. Most of it is a desert. There are a few boulders here and there. It is impossible to exert the power of this mecha. And this huge underground city is the future living base of the meteorite belt hunters. Zhou Sen

Naturally, I can't bear to destroy it.

Next, the two of them walked around this huge underground city for a while and saw countless strange things, but there was no such surprise as the exoskeleton mecha.

After walking around for a whole day, Zhou Sen and Bing Ling finally returned to the surface of the planet.

This whole day was not just about walking and shopping. In the back, most of the time was spent flying with a sword. After all, this underground city is too huge.

In fact, even when flying with a sword, the places Zhou Sen and Bing Ling visited were just the tip of the iceberg.

You can imagine how huge this underground city is, because this city is actually a planet that is completely hollowed out.

When Zhou Sen and Bing Ling returned to the ground, they were both in a daze.

Although the two people's vision was a little tired after a day of sightseeing, when they came out of the huge dungeon, the contrast in visual impact compared to the wilderness outside was still extremely shocking.

At the same time, both of them were thinking about how many people would live in that huge underground city?

Where did those people go?

During this day's search, the two of them did not find any useful clues. In the vast underground city, there were traces of human activities everywhere, but they could not see a single person, not even a single person.

No corpses were seen.

No staff were seen in the city's hub, the city's main control room.

All instruments, equipment, and infrastructure in the underground city are operating automatically, and even the underground transportation vehicles are operating in an orderly manner according to established patterns.

The entire underground city is filled with an extremely weird atmosphere.

What force could make such a huge underground city empty?

Zhou Sen could not give a reasonable answer.

As an awakened human being, Bing Ling cannot be explained by science.

Of course, the two of them did not gain nothing. In addition to harvesting a lot of useful things, Zhou Sen also gained an exoskeleton mecha. In addition, they also found out about the war that only heard and ignored the people.

The credit goes to Bing Ling. When the two arrived at the city's main control room, Bing Ling quickly understood the ins and outs of the matter.

Everything originates from the huge metal crust of the underground city. In fact, it is a huge instrument. When it is hit by an external force, it will generate a force to form Gang Qi. At the same time, it will also simulate ancient times.

The sound of war...

…

Many things seem complicated, but are very simple.

But a dungeon without a person is extremely complicated.

Zhou Sen is a person with vast supernatural powers, and Bing Ling is an awakened human being with profound knowledge. However, both of them cannot explain why there is no one in the dungeon. It seems that in an instant, everyone

People have disappeared.

Zhou Sen believes that even the most powerful gods with super powers cannot do this.

It is easy to destroy the underground city, but it is simply impossible to make the hundreds of millions of humans in the underground city disappear at the same time without destroying the underground city.

Regarding the number of humans, Zhou Sen and Bing Ling reached a consensus and both believed that there were at least more than 100 million humans living in this underground city, and this was still an extremely conservative estimate.

Zhou Sen spent the next three days searching, believing that he would always be able to find some clues.

And Bing Ling, during these three days, was also looking for clues in the city's main control room.

Zhou Sen gained nothing, but Bing Ling gained a lot because she deciphered the city code, entered the city's main control optical brain, and called up the entire city's monitoring system.

Under the surveillance information, the prosperous side of the city appeared in front of them.

Busy traffic, hustle and bustle, some warm families, some heart-wrenching stories.

The surveillance footage made Zhou Sen seem to have returned to the five star regions.

This is a city that is very similar to the cities of the five stars. The only difference is that it is underground. Of course, the technological level here is much higher than that of the five stars. The quality of the residents here is even higher than that of people from the five stars.
