"I don't understand this, in theory, the temperature you just emitted can't melt it...... Actually, you didn't really melt it just now, the property of this metal is that as long as it does not reach the maximum temperature it bears, it can return to its original state, and it can recover quickly just now, which means that you just let it deform, not really melt...... Hey, why don't you put it on and try it, this exoskeleton mecha can strengthen the strength, if the strength of ordinary people is two hundred kilograms, after strengthening through it, it will be at least two thousand kilograms, or even more, maybe it will be of some use to you. Bingling said excitedly.

"Haha, I'm a superpower, this thing doesn't mean anything to a superpower." Zhou Sen laughed and said disapprerovitically.

"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 are able to compete with the gods, and in fact, we do. This intelligent memory metal, called soul metal by our awakened human beings, only the awakened warriors of the high plane can have a little bit, the so-called little bit, maybe a large piece of nails, can strengthen the power of a mecha, and even a spaceship several times, and like this kind of pure soul metal composed of luxury exoskeleton mecha, you can't even think about it, its terrifying power, you can imagine! Bingling's expression was extremely serious.

"I'll try." Zhou Sen saw Bingling's serious face, and didn't want to accept her kindness, "But, how do I wear it?" ”

"Remove the surrounding fixed brackets and stand in the middle of the exoskeleton."

"Oh......"

Zhou Sen nodded, directly melted the fixed bracket of the exoskeleton mecha with the non-extinguishing essence, and then walked straight from the side.

A bizarre scene appeared.

The pitch-black mecha that was originally a head taller than Zhou Sen began to shrink, and it was tightly attached to Zhou Sen's body, the size was just right, and some of the joint parts were simply seamless.

"Does this thing have the light brains on your ship?" Zhou Sen looked at the super jet-black metal clinging to his body in surprise.

"No, this is the magic of soul metal, it itself has extremely high intelligence, it can absorb your brain waves, and then, through the intelligence of the metal to analyze your needs and purposes, of course, this ability, can only be pure soul metal can have, like we awaken human beings usually use soul metal as an alloy smelting, strengthen the ability of some key parts of the spaceship, but have a certain self-repair function, not to mention intelligence."

"There's such an amazing metal!" Zhou Sen exclaimed.

"Actually, I've always thought that it's not really a metal, it's supposed to be a mysterious species, it's just that it exists in the form of metal." Bingling said.

"Makes sense! If it is really an inanimate metal, it will never comprehend the human mind, let alone analyze brain waves...... I'll try it......"

Zhou Sen said as he walked to a huge metal pillar, this metal pillar is hugged by two people, somewhat similar to the Roman column of the earth, which is used for decoration and is not load-bearing.

After walking in front of the metal pillar, Zhou Sen stood up and did not urge the superpower, but used the strength of his limbs to gently punch the metal pillar.

said that a light blow is just for Zhou Sen's strength, after all, if Zhou Sen's "Invincible Cheats" is used with all his might, let alone this metal pillar, even if it is the entire shopping mall, it will be wiped out.

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

The strength of five ordinary people should reach at least five hundred catties or more.

According to Zhou Sen's thoughts, this kind of power, in the face of the metal pillar that these two people hugged, was simply negligible.

"Whew"

The sound of the howling wind blew through the silent mall.

"Phew!"

A slight thud rang out in the quiet mall.

"Ah......h

Zhou Sen's whole person was petrified, and there was an incredible expression in his eyes. At the same time, Bingling, who was watching, was also dumbfounded.

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

Zhou Sen began to predict that this exoskeleton mecha made of soul metal should be able to knock down this metal pillar, but he never dreamed that he would actually penetrate it directly, and it was obvious that soul metal not only enhanced his strength, but also strengthened his speed.

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

Zhou Sen suspected that the metal pillar was too fragile, but he didn't use the fire to refine it, and immediately found that the metal pillar was also alloyed, although the material could not be compared with the metal of those cold weapons, but it was many times stronger than the materials of some cold weapons on the earth.

In the face of such a sturdy metal pillar, not to mention this light punch, even if Zhou Sen used the "Invincible Cheats", he could only knock the metal pillar flying, and he couldn't fall into it as easily as he did now.

"What a strong force!"

Zhou Sen, who came to his senses, couldn't help but gasp, and repeatedly checked the structure of this exoskeleton mecha, and even searched with his divine sense, but he didn't find the slightest thing, and even he, he didn't find the power device of the exoskeleton mecha.

The entire exoskeleton metal mecha is integrated, like a hollow black metal frame, if it weren't for Bingling to say, he wouldn't have been able to imagine that this hollow metal bracket has a relationship with a mecha full of science fiction.

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

"Hehe, this is the magic of soul metal, it doesn't need power at all, it can achieve the strongest mechanical effect." Bing Ling said with a smile: "The only fly in the ointment of this exoskeleton mecha is that the industrial design is too poor, if it is smelted with the industrial level of our awakened human beings, it will 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, why don't you design it from scratch? Oh...... No, you can only leave it in a liquid state temporarily, and you can't completely change it......"

"That's actually pretty good." Zhou Sen shook his head, although he felt that the shape of this exoskeleton mecha was a little weird, but it was extremely comfortable to wear on his body, and it was extremely in line with the principle of ergonomics, as long as it could be melted and collected into the Qiankun ring at any time, it could be directly summoned and put on when used, and it was very convenient to put it on and take it off without trouble, and there was no need to refine.

Of course, the main reason is that Zhou Sen is afraid of destroying the internal structure of the soul metal, in case he doesn't use the fire essence to refine it indiscriminately and scrap this rare and rare metal, it will be a big loss.

Now, what Zhou Sen wanted to do most was to find a place to test how much power this mecha could burst out, and in an instant, Zhou Sen broke this idea.

This planet is extremely desolate, most of the places are deserts, and occasionally there are a few boulders, which cannot exert the power of this mecha at all, and this huge underground city is the future life base of the meteorite belt hunter, Zhou Sen naturally can't bear to destroy it.

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

After a whole day of shopping, Zhou Sen and Bingling returned to the surface of the planet.

This whole day is not just a walk and shopping, in the back, most of the time, is Edgeworth flying, after all, this underground city is too huge.

In fact, even if it was the flight of Edgeworth, the places visited by Zhou Sen and Bingling were only the tip of the iceberg.

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

When Zhou Sen and Bingling returned to the ground, they were in a daze.

Although the two of them were a little tired from the day's tour, when they came out of the huge dungeon, compared to the wilderness outside, the contrast of visual impact was still extremely shocking.

At the same time, both of them were thinking, how many people will live in that huge dungeon?

Those people, where did they go?

During this day's search, the two did not find any useful clues, in the vast underground city, every place, there were traces of human activities, but they couldn't see a single person, even a corpse, they didn't see it.

In the hub of the city, in the city's main control room, there were no staff members in sight either.

All the instruments and equipment in the underground city, as well as the infrastructure, are running automatically, and even the underground vehicles are also running in an orderly manner according to the established pattern.

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

What is it that can make such a huge underground city empty?

Zhou Sen could not give a reasonable answer.

Bingling, as an awakened human being, cannot be explained by science.

Of course, the two of them did not gain nothing, in addition to collecting a lot of useful things, Zhou Sen also harvested a pair of exoskeleton mechas, and in addition, they also figured out the war that only heard their voices and did not see them.

The credit goes to Bing Ling, and 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, and when it is hit by an external force, it will generate a kind of force, form a gangqi, and at the same time, simulate the sound of ancient wars......

……

Many things, as complex as they may seem, are simple.

And a dungeon without one person is incomparably complicated.

Zhou Sen is a superpowered person with great powers, and Bing Ling is an awakened human with great knowledge, but the combination of the two of them can't explain why there is no one in the dungeon, as if in an instant, all the people have disappeared.

Zhou Sen believed that even the most powerful gods with superpowers could not do this.

It's easy to destroy a dungeon, but it's simply impossible to make hundreds of millions of humans disappear in the dungeon at the same time without destroying the dungeon.

Regarding the number of human beings, Zhou Sen and Bingling reached a consensus, and they both believed that the number of human beings living in this dungeon exceeded at least 100 million, and this was still an extremely conservative estimate.

For the next three days, Zhou Sen searched for the next three days, and he believed that he would always be able to find a little clue.

And Bingling, in the past three days, was also looking for clues in the city's main control room.

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

Under the surveillance information, the prosperous side of the city was presented in front of the two.

Busy traffic, bustling, some warm families, some tearful stories.

The surveillance screen made Zhou Sen feel as if he had returned to the five star fields.

This is a city that is very similar to the city of the five stars, the only difference is that it is underground, of course, the level of science and technology here is much higher than that of the five star fields, and the quality of the residents here is not comparable to the people of the five star fields, as for the spiritual and material, between the two, it is not at the same level.

Such a powerful civilization suddenly disappeared, leaving behind only a ruins beyond human imagination.

No result.

Even if a large number of surveillance videos were found, there was still no result, because the surveillance video did not record the process of the sudden disappearance of human beings......

……

Starlight is like silver.

Zhou Sen and Bingling sat side by side by the lake, looking at the vast stars in the sky.

"When are we leaving?" Bing Ling leaned on Zhou Sen's shoulder very naturally.

"Let's go?" Zhou Sen smelled the faint fragrance emanating from Bingling's body, and a wry smile appeared on his face.

"What's wrong?" Bingling sat upright.

"I don't have coordinates, and here, there is no teleportation array." Zhou Sen sighed.

"You mean there's no way you can get out of here?" Bingling looked at Zhou Sen in surprise, she remembered that Zhou Sen said with confidence that she could leave here.

"I might be able to leave." Zhou Sen hesitated for a moment.

"Because of me?" Bingling Bingxue was smart and immediately asked.

"This ...... There is a little ......" Zhou Sen wanted to speak and stopped.

"Say, I don't mind." Bingling sat upright, her face calm.

"Although I don't have the coordinates to return to the Gods and Demons Continent, and I don't have a teleportation array, I can fly out of here in the stupidest way, I just need to choose a direction and keep flying, it doesn't matter if the direction is right or not......"

"What you mean is that you can fly forever, for decades, hundreds, or even thousands of years, because you are a half-immortal body, and you don't care about time at all, in this boring flight, you can cultivate, you can run your own Shentai world, in fact, you will not be lonely, because, you have the Shentai world, and in your Shentai world, you have countless people, who can not only provide you with food, but also provide you with a steady stream of faith power...... One day, you will encounter a planet inhabited by humans while flying, and if you are lucky, you will encounter an ancient teleportation array, and you can directly reach the human world......"

"Yes." Zhou Sen looked at Bing Ling blankly, he couldn't imagine that Bing Ling could guess his mind at once.

"I've become a burden again." Bingling showed a bitter smile on her face.

"No, I'm not going to leave yet." Zhou Sen shook his head.

"Why?" Bingling's eyes lit up.

"If there is no goal in flying in the vastness of the universe, time has lost its meaning, so what is the point of decades earlier and decades later? So, I decided to stay here with you. ”

"Stay with me? Until I'm old? ”

"Ahem......"

"And then, you're going to get out of here?"

“……”

"If so, I'd rather go with you." Bingling said.

"I think flying in the stars is very boring......"

"I'd rather endure the endless boredom than delay even a day, because you still have four women waiting for you, and the kind of interstellar flight you are talking about, encountering human settlements and teleportation arrays, is completely by chance, perhaps, on the third day we leave here, if we are lucky, we will be able to encounter an ancient teleportation array left by the gods, or find the interstellar coordinates you need."

"This ......"

Zhou Sen opened his mouth, and he wanted to stop talking, he was entangled in this question, because, when he was flying in the interstellar space, he happened to encounter a meteorite belt, and he met the Tongtian God Mouse, which is enough to show that there is a big difference between leaving early and leaving later.

"You have two choices, first, abandon me here; Second, take me away! "Bingling cut the railway.

"You...... Not afraid of loneliness? ”

"Don't be afraid." Bing Ling's clear gaze revealed an extremely resolute look.

"Alright, let's get off when your lessons are out."

"Okay."

……

The so-called curriculum is to use the equipment in the dungeon to develop the curriculum, and the content of the curriculum is mainly to teach some basic scientific knowledge, including the curriculum from basic education for young children to higher education.

Because Zhou Sen and Bingling are leaving, the only way is to arrange the course on the computer.

The people in the meteorite belt belong to the people of the cold weapon era, and it is undoubtedly a fool's dream to let them fully master the technology of the dungeon, so Bingling's course is mainly to master some simple operations, and more courses focus on the education of new children.

If you follow the curriculum education arranged by Bingling, between twenty and forty years at most, you can cultivate a group of young people who can use the equipment of the dungeon, of course, if you want to fully digest the scientific knowledge of the dungeon, it will take at least a hundred years, and they will need to continue to explore.

No one can predict what kind of civilization the hunters will be able to breed on the basis of the dungeon, after all, there are too many human factors, and the slightest disconnection may lead to another direction of development.

What Bing Ling did was just to do her best, if nothing else, according to Bing Ling's arrangement, this planet would be brilliant again.

The dungeon provides a near-perfect living space for the hunters who migrate here, here, there is no need to worry about life at all, and there are no natural enemies, even in case there are invaders from outside, the defense of the dungeon is enough to resist most of the strong people, you know, when the collision resonates the anger, but even Zhou Sen, a superpowered person with a half-immortal body, is deeply afraid.

Until now, Zhou Sen still hasn't figured out the principle of the generation of those gangqi, after all, it doesn't belong to the category of science, of course, it doesn't belong to the category of cultivating gods, if you insist on finding a reasonable explanation, it can only be said that science combines the miracle created by cultivating gods.

Bingling worked at full capacity for five days and finally finished her job.

I have to say that Bingling is a careful woman, and her courses, in addition to telling adults to master some simple mechanical operations, have been arranged for young children until they are thirty years old.

If Bingling completes all of Bingling's courses, then the adult child will become an excellent scientist.

After the course, Bingling still has a lot of arrangements, that is, when all the courses are completed, some more esoteric knowledge will appear gradually, when the learner himself knows how to control the equipment of the dungeon and begins to study purposefully, Bingling's work is truly completed......
