Chen Sheng stared at the dark wall and was speechless.

Nanotechnology, a civilization technology with high potential on the scientific and technological side.

To put it simply, this technology is a technical means to reassemble, decompose, arrange and manufacture substances by controlling matter at the nanoscale or even a more microscopic level.

Sound familiar?

The reason why Chen Sheng knows about nanotechnology is that the mother box in his hand is equivalent to an outstanding work derived from super nanotechnology.

The super nanotechnology means contained in the mother box can directly transmit this transformation instruction from the energy level without relying on matter, extremely violent and quickly transform things from the extremely microscopic fractional/atomic level, and this transformation is very stable and mature, and even the three mother boxes are integrated to form a trinity, and the power of the mother box can touch the deeper subatomic realm, and even envelop a planet, and quickly retransform and arrange the material composition of a planet.

Among the 100,000 worlds of knowledge possessed by the mother box, there are no less than hundreds of different nanotechnology variants that are ordinary or high-end.

Of course, on the whole, it is basically not as strong as the mother box.

But it doesn't mean that the technical level of the mother box is the ceiling of the universe.

The potential of nanotechnology is almost limitless.

Of course, the composition of the mother box itself is far more than a transcendent nanotechnology, as the legacy of the ancient Apocalypse Star civilization, the mother box itself integrates the same incredible [micro eternal energy], [force field technology], [indestructible material], [hyperspace teleportation], and even can achieve similar psychic projection power, in the words of the Amazon once said that the mother box is 'like a magical technological creation'.

Chen Sheng didn't expect to see the appearance of nanobots on this sky fortress at this time.

This reminded him that when he was searching for information on the Avengers, he saw gossip that Stark Industries had made a breakthrough in nanotechnology.

Could it be the Iron Man's handiwork?

Chen Sheng remembered the scene where the two sat and chatted before, and remembered the Tony Stark who was wearing glasses and talking eloquently, what was he talking about at the time? Going to study a spaceship?

Now that I think about it, for this genius on the technology side, I'm afraid it's really not just talking.

If he really wanted to get a spaceship.

Chen Sheng carefully looked at the behemoth-like sky fortress in front of him, if it was really nanotechnology, Ultron would have more means than he imagined.

Although his knowledge of these technologies only stays in the theory of cramming, through the comparison of knowledge, the material strength of these nanomachines alone is enough to prove that this is a very advanced nanotechnology.

All were shaped by an unknown metal beyond vibranium, and if these things were active, even he might not be able to withstand the attacks of these things if he was unsuspected.

However, at present, it seems that this sky fortress is very quiet, there is no abnormal movement, even if Chen Sheng cut a wall just now, it is only restored, and there is no other situation.

With a look of thought, Chen Sheng did not continue to do anything to this sky fortress easily.

He quickly teleported back to Kama Taj on the ground.

Chen Sheng, who suddenly appeared, immediately attracted the attention of the others.

At this moment, Steve Rogers was inspecting the injuries of the other injured black-clothed warriors with his companion Falcon, and someone else put the unconscious Wanda on handcuffs and anklets, and when he saw Chen Sheng's suddenly disappeared figure reappear, Steve immediately got up and walked towards Chen Sheng in three steps and two steps.

"Captain!"

The falcon, which was squatting on the ground and bandaging the wounds of a warrior, glanced at Chen Sheng.

There was a hint of worry in his eyes, and he subconsciously reminded Steve.

However, the former Captain America did not have any vigilance or concern about Chen Shengsheng, and he came to Chen Sheng's approach without pausing, and a pair of blue eyes on his vicissitudes of cheeks looked at the black-haired young man in front of him seriously.

"I don't know how you did it, thank you for saving Wanda. He also saved my companions. ”

"I'm Steve"

He said, intending to extend a hand, as if to shake it in thanks.

"Steve Rogers."

Chen Sheng watched the other party's movements and spoke first.

"I know, I guess there should be very few people who don't know you."

"Hehe, maybe it's my pleasure, Mr. Mage."

Steve was stunned for a moment, retracted his hand without a trace, and then shook his head with a wry smile.

"Where are you from?"

In the sky, Dr. Strange slowly descended, his blind eyes 'looking' at Chen Sheng, as if he was thinking and looking.

"I feel a mystical energy that is different from our world, and it seems to be, it is not"

He muttered, silent for two seconds, before he spoke as if he had an answer in his heart.

"Is Your Excellency an occult mage from another dimensional universe?"

"Hello, this mage, I don't know what to call it?"

Chen Sheng turned his head to look at the other party.

A high-level arcane mage, but severely disabled, made him look at it twice.

"Strange."

The latter replied.

"I'm Stephen Strange. I used to be a doctor. ”

"I'm Chen Sheng. As you can see, a traveler. ”

Chen Sheng was slightly surprised, but he seemed to have expected this answer.

Have we finally met? I didn't expect it to be in this situation.

The person in front of him was the source of many arcane knowledge in his mind.

A disciple of the Ancient One, a candidate for the position of Supreme Venerable.

Of course, in this parallel world numbered as the 01 Primogem Universe, he wasn't sure that everything could be copied from his World 00 Realm, but judging from the fact that Strange was still a mystic mage, maybe some things could still be right.

Once upon a time, just nearly half a month ago, he relied on the incredible power brought by this time gem to inherit part of the power of this mystical master, and he barely became a low-level mystical mage.

However, since then, he has relied on the power of the gem's continuous upgrading, and now Chen Sheng has stood at the near apex of the high-level secret magic mages, and after truly and completely mastering the power of the six fragment primordial stones, in terms of his comprehensive strength, even some ordinary supreme mages of the past generations will not be his opponents.

However, this ascension did not make him complacent, because compared to those cosmic god-level or even higher-level existences, his current power was nothing in the multiverse.

After Chen Sheng briefly introduced himself, his eyes glanced at the chest of Strange's secret robe as if he were subconscious.

But he didn't see what he wanted to see.

"Where is the Time Rough Stone now?"

He asked bluntly.

"You're looking for rough gems from other worlds?"

Dr. Strange closed his eyes as if he understood something.

"No wonder I felt the power of the original stone in you just now, you are very extraordinary, not a simple arcane mage."

He pondered for a moment before continuing.

"The Time Rough Stone has long been lost, and if you are here to find the whereabouts of the Time Rough Stone, I'm afraid it will not be an easy task."
