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

The scene just now was too fast, and he was held by Shen Feng under his arm, swinging back and forth, which was even more uncomfortable than riding a roller coaster.

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

After vomiting a few times, he felt that he was almost stable. Billy immediately wiped his mouth and turned around to look at Shen Feng with an apologetic smile.

There were several huge Arabic numerals written on a metal wall not far from them.

2981.

They are already approaching the three thousandth floor.

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

After all, there are countless hardships and twists and turns involved, especially those mechanical monsters that block and chase them. Just trying to find the right stairs is a lot of trouble.

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

It is estimated that even those expedition teams have never been here.

Shen Feng ignored Billy at this time and began to carefully check the status of the nanomachinery cluster through the silicon-based brain.

Each nanomechanical insect has an energy storage device inside. Although it does not store much energy, the total amount is extremely considerable.

And these gadgets themselves can absorb solar energy for energy storage.

But even so, after a violent energy output, it still needs to be recharged.

After all, there is no sunlight inside the super giant structure.

According to the information stored in the nanorobot, charging needs to go to a charging station on the 1500th floor in the southwest direction.

Each charge can last about seven days of activity.

Another method is to directly eat other substances, such as chewing carbohydrates, to produce a certain degree of energy through the process of chemical energy conversion.

Now the nanorobot controlled by Shen Feng, also known as the construction machine, does not have much energy left.

It can still run for about seven hours.

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

"Can you think of a way to change its charging mode? For example, convert the mechanical kinetic energy generated by my movement into energy storage, store it in the nanomechanical insect, and use it when needed?"

Jingwei’s voice sounded:

"I can give it a try, deduce the model, and then let these nano-mechanical bugs transform each other... Although they can't eat each other, it should be possible to transform each other at the micro level... This kinetic energy conversion mechanism is too old-fashioned. The principle is the same as the electric bicycle power-assist device.”

Shen Feng nodded, as long as it can be reformed.

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

Even if he really failed, the worst he could do was find a charging station to recharge, and take a look at what was going on with those nano-robots and see if there was any super will behind them controlling everything.

With those electromagnetic pulse bombs in his pocket, it won't matter if his disguise is discovered.

"Shen Feng, you still have to be careful. The iteration time of these nano-robots is different, and their resistance to electromagnetic pulses is also different. Have you noticed that the construction machine you control is much more resistant to electromagnetic pulses. "

Guessing Shen Feng's thoughts, Jingwei warned cautiously.

Shen Feng nodded, also a little more wary.

What Jingwei said is correct.

At present, it seems that what remains at the bottom of the super giant structure are all early and old models of nanomechanical insects, which are developing in a state of disorder.

This also resulted in the underlying structure being very messy, as if it were abstract art.

Moreover, these old models of nanomechanical bugs have all lost their energy, or due to problems with their own design instructions, they have completely fallen into dormancy after becoming part of the structure. In other words, they have lost the activity of nanomechanical bugs and died. Lost.

And the higher you go, the newer the nanomechanical bug models will be, the more various bugs will be improved, and the fewer weaknesses will become.

Perhaps when he completely travels through the entire super-giant structure, he will encounter nano-mechanical insects with no flaws or weaknesses at all. It will be the most terrifying gray tide.

Before that, he must collect enough intelligence so that he can handle everything...

Just as Shen Feng was thinking, there was suddenly a sound of water in the distance, and there seemed to be a faint sound of human voices.

He looked at Billy with questioning eyes, and Billy immediately said in a trembling voice:

"It... it should be this area... I haven't been to this level before, I just heard what others said..."

Shen Feng nodded, his appearance transformed into Mike's black and strong appearance again, and he quietly walked towards the direction of the sound with Billy.

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

Not only are there no chaotic structures here, everything seems orderly, and there are even some decorative structures.

It was no longer the kind of structure inside an office building or factory. What appeared in front of Shen Feng and Billy was a huge and wide area, with a high dome above it, like the silver-gray sky.

In this vast area, there are metal trees, rocks, and even metal flowers and plants standing, like a jungle.

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

But in front of Shen Feng, there is a wide river!

The channel of this river is also entirely made of metal, but the entire river is winding and winding. If you ignore the metal river bed and river banks, it is a river as wide as forty or fifty meters.

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

But this is nothing.

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

There are a lot of moss and algae-like things attached to those metal river banks!

biology!

At the same time, there were actually several cockroaches crawling around the river bank.

The significance of all this is really too great!

This shows that even in this super giant structure with metal structure, life is still going on and will never stop!

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

Soon enough, a black shadow passed by in the water. Shen Feng's eyes widened and he rushed forward. A sharp metal tentacle suddenly emerged from the arm covered by the nano-mechanical insect, and it instantly pierced into the black shadow. .

The next moment, Shen Feng suddenly pulled, and a palm-sized grass carp was lifted out of the water.

fish!

There are actually fish in here!

The moment he saw this fish, Billy's eyes almost popped out of his head, and his stomach immediately began to growl.

It had been so long since he had eaten fish that he had almost forgotten the taste of fish.

If he had a choice, he wouldn't want to eat human flesh!

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

Time flies. After almost half an hour, Shen Feng has relied on his keen eyesight and speed to hook seven or eight fish in this river that is thirty or forty meters deep.

The food was basically gone, with only a little bit of dregs left. He had even seriously considered draining Billy's blood when he was completely out of food.

It seems completely unnecessary now.

This is not a completely metalized world with no vegetation, there are still fish, cockroaches, and algae!

Billy on the side was even more excited, looking at these fish was like seeing a saint.

Shen Feng took out a dagger and cleaned all the fish. He took out a small liquefied gas tank and some remaining seasonings from his backpack and started grilling the fish.

Billy had never seen such a battle before. He was so shocked that his eyes almost popped out, and he kept swallowing his saliva.

But he also understood that it was impossible for him to eat fish.

It's lucky not to be eaten.

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

Billy rushed to the shore, scraped a lot of water plants from the metal river bank, washed it, and held it in front of Shen Feng like a treasure.

At this time, the fish has been brushed with oil and seasoned and almost grilled. There are seven fish in total, and the aroma is fragrant.

Shen Feng took one of them, smelled it, and bit into it. It was crispy and soft, and he showed a satisfied smile.

Although there is still a bit of fishy smell, the requirements are not that high under these conditions.

Then I grabbed a handful of algae and put it into my mouth. Although the taste was a bit bland, it still had a faint fragrance. It complemented the grilled fish perfectly.

Shen Feng nodded with satisfaction.

Finally no need to run out of food.

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

"Eat."

Billy couldn't believe his eyes, and burst into tears of gratitude. He took it with great gratitude and began to eat it quickly, including the fish head and fish bones, which he chewed and swallowed.

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