"Vomit ......" Billy vomited so much that he felt like he was about to vomit out his intestines.

The paragraph just now was too fast, and he was caught under Shen Feng's armpit, and the whole person was swinging around, which was even more uncomfortable than a roller coaster.

It's just that he didn't even dare to vomit for too long at this time.

After spitting a few times and feeling almost stable, Billy immediately wiped his mouth, turned around and looked at Shen Feng with a smile on his face.

Not far from them, on a metal wall, several huge Arabic numerals were written.

2981。

They are already close to three thousand floors.

At the speed of those prisoners, it would take at least a few months for the expedition team to reach the third thousandth floor.

After all, I don't know how many hardships and twists it will have to go through, especially those mechanical monsters to stop and kill, and it will take a lot of trouble just to find the right staircase.

And now, in just over a day, they have crossed the distance of two thousand floors!

Here, even those expeditions are estimated not to have been there.

Shen Feng didn't pay attention to Billy at this time, but began to carefully check the status of the nanomachinery cluster through the silicon-based brain.

Inside each nanorobotic worm, there is an energy storage device, although it does not store much energy, but the total amount is extremely considerable.

And the things themselves absorb solar energy for energy storage.

However, even if this is the case, it still needs to be recharged after a violent energy output.

After all, there's not much sunlight inside the supermassive structure.

According to the information stored in the nanobots, charging requires traveling to a charging station on the 1500th floor of the down-southwest direction.

Each charge lasts for about seven days.

Another method is to directly swallow other substances, such as gnawing carbohydrates, to produce a certain amount of energy through the process of chemical energy conversion.

Now the nanobot controlled by Shen Feng is also a construction machine, and there is not much energy left.

It can still run for about seven hours.

Shen Feng frowned, carefully checked the situation of these nanomechanical insects, and said to Jingwei:

"Can you think of a way to change it to a charge mode? For example, the mechanical kinetic energy generated by my movement is converted into energy storage, stored in the nanorobotic worm, and then used when needed? ”

Jingwei's voice rang out:

"I can try, deduce the model, and then have these nanorobotic worms modify each other...... Although we can't devour each other, it should still be possible to transform each other at the micro level...... This kinetic energy conversion mechanism is too old-fashioned to be old-fashioned, and it is the same principle as the electric bicycle booster device. ”

Shen Feng nodded, it would be good if it could be transformed.

Although it will take time, as long as Jingwei succeeds, it will be much more convenient in the future.

Even if he really fails, it's a big deal for him to find a charging station to recharge, and by the way, see what the situation is with those nanobots, and whether there is a super will behind them to control everything.

With those EMP bombs in your pocket, even if the camouflage is recognized, there is nothing.

"Shen Feng, you still have to be careful, these nanorobots have different iteration times, and their resistance to electromagnetic pulses is also different, have you found it, the construction machine you control is much more resistant to electromagnetic pulses."

Guessing Shen Feng's thoughts, Jingwei cautiously reminded.

Shen Feng nodded, also a little more vigilant.

Jingwei's words are correct.

At present, it seems that the bottom of the supergiant structure is all early old nanorobotic worms, and there is a state of disorderly development.

As a result, the underlying structure is very messy, as if it were abstract art.

Moreover, all of these old models of nanorobotic worms have lost their energy, or because of their own design instructions, after becoming part of the construct, they have completely fallen into dormancy, or they have lost the activity of nanorobotic worms and died.

And the higher you go, the newer the model of the nanorobotic worm, the more various bugs will be improved, and the fewer weaknesses will become.

Perhaps when he completely penetrates the entire super-giant structure, he will encounter nanomechanical insects that are completely devoid of any flaws and weaknesses, and it will be the most terrifying gray tide.

Before he could do that, he had to gather enough intel to be able to handle everything......

Shen Feng was thinking about it, when there was a sudden sound of water in the distance, and there seemed to be a faint human voice.

Looked at Billy with an inquiring look, and Billy immediately said in a trembling voice:

"Should...... This is probably the area...... I've never been to this floor, I've only listened to other people......"

Shen Feng nodded, his appearance transformed into Mike's black appearance again, and he walked silently in the direction where the voice came from with Billy.

The overall structure of the 2981 floor is completely different from that below the 1000 floor.

Not only is there no chaotic structure, everything seems to be in order, and there are even some decorative structures.

Instead of the interior structure of office buildings and factories, what appeared in front of Shen Feng and Billy was a huge and wide area, with a high dome above, like a silver-gray sky.

This vast area is filled with metal trees, rocks, and even metal flowers, making it look like a jungle.

Of course, everything is made of metal, and there is no trace of life.

It's just that in front of Shen Feng's eyes, there is a wide river!

The course of the river is also entirely made of metal, but the whole river is meandering, and if you ignore the metal bed and banks, it is a river forty or fifty meters wide.

Against the backdrop of the dome and the occasional lights around it, the river on the 2981st floor looks very strange.

It's just that it's nothing.

What really excited Shen Feng was that there was something green in the river!

On the banks of those metal rivers, there are a lot of moss and algae-like things attached to them at this time!

Creature!

At the same time, around the riverbank, there were several cockroaches crawling.

The significance of all this is so great!

This shows that even in this super-giant metal structure, life is still alive and will never stop!

Moreover, with algae, which is at the bottom of the food chain, there will be a higher level of life!

When it was too late, a black shadow swept through the water, Shen Feng stared, and suddenly pounced, and the arm wrapped in nanomechanical insects suddenly poked out a sharp metal tentacle, instantly piercing into the black shadow.

In the next moment, Shen Feng suddenly tugged, and a palm-sized grass carp was hooked up from the water.

Fish!

There's even fish in there!

The moment he saw the fish, Billy's eyes almost popped out, and his stomach immediately began to gurgle.

He hadn't eaten fish in so long that he had almost forgotten the taste of it.

If there is a choice, he doesn't want to eat human flesh!

Shen Feng looked happy, took the fish off and put it aside, continued to stare at the river, and after a while, he flicked his tentacles and hooked out a fish again.

Time flew fast, and after almost half an hour, Shen Feng had already relied on his keen eyesight and speed to hook seven or eight fish in this river that was thirty or forty meters deep.

The food was almost gone, and there was only a bit of dregs left, and he had even seriously considered whether to suck Billy's blood dry when he ran out of food completely.

Now it seems completely unnecessary.

It's not a completely metalized world, there are still fish, there are cockroaches, there are algae!

Billy was even more excited, looking at these fish was almost like seeing a saint.

Shen Feng took out a dagger, disposed of all the fish with his hands, took out a small liquefied gas tank from his backpack, and some remaining spices, and began to grill the fish.

Billy had never seen such a battle, and his eyes were so shocked that he was about to pop out, and he kept swallowing his saliva at the same time.

But he also knew that he couldn't eat fish at all.

It's a blessing not to be eaten.

"Go, get some water and weeds." Shen Feng said, throwing him a plate.

Billy hurriedly rushed to the shore, scraped a lot of aquatic plants on the metal riverbank, washed them, and held them in front of Shen Feng like a treasure.

At this time, the fish has been brushed with oil and seasonings and grilled almost to the bottom, a total of seven fish, fragrant.

Shen Feng took one of them and sniffed it, took a bite of it, it was crispy and soft, and showed a satisfied smile.

Although it still smells a little fishy, the requirements are not so high under this condition.

Grab a handful of algae and put it in your mouth, although the taste is a little bland, but there is still a faint fragrance, which complements the grilled fish well.

Shen Feng nodded with satisfaction.

Finally, I don't have to run out of food.

Soon, after eating five fish, there were still the last two, Shen Feng picked up one of them and handed it to Billy:

"Eat."

Billy couldn't believe his eyes, and with gratitude, he took it and began to eat it quickly, including the head and bones, all of which he chewed and swallowed.

Even the fish bones and fish heads that Shen Feng had thrown away were carefully picked up by him and eaten them all.

Shen Feng looked at Billy, who was eating fish with a handful of snot and tears, and couldn't help but smile without the slightest emotion.

Let's eat...... My battery.

At this moment, there was a faint shout of a human in the distance, Shen Feng frowned, and quickly packed all kinds of things into his backpack.

Wrapped in nanobots again, turning into Mike's black appearance, slowing down, Shen Feng took Billy and walked silently in the direction where the voice came from.

Soon, they could already see several figures standing by the river, holding a battered fishing net in their hands, shouting and fishing.

The men were all dressed in shabby and patched clothes.

The style of the clothes is uniform, orange, but it has faded very badly.

It's just that Shen Feng has seen this dress before.

On the 33rd floor, the worker who was devoured in ashes and became a metal statue wore this uniform.

Although the clothes had been metallized, Shen Feng could still see the ornaments on it.

On the chest and back of the uniform, there are the stars and the logo composed of five characters.

Sky Technology.
