There was no sudden attack, and there was no threatening move.

457 just stared at Zhang Jike for a while, and finally sighed and half-squatted in front of the middle-aged soldier.

Changing his previous defensive attitude, he introduced himself in a friendly manner.

"Reacquaint, my name is Zhang Heng, and I'm the Elder from Timeline 457."

"The Elder ......," Zhang Jike muttered, desperately digesting every word in the young man's mouth.

If it had been placed a month ago, if a middle-aged soldier had heard such words, he would have thought that there was something wrong with the young man in front of him.

But since seeing Hamilton, the 'terminator', Zhang Jike's worldview has long been reshaped, and now he has a very strong ability to accept.

"Zhang Jike." After a moment of silence, Zhang Jike politely reported his name, although he didn't understand what Zhang Heng's 'Boundary Breaker' meant.

And 457 didn't speak, just waited silently in place, as if he had expected that Zhang Jike had a lot to ask.

"What does the Elder mean......" was silent for a while, Zhang Jike still decided to pretend not to understand, and honestly asked the doubts in his heart.

"It's a bit of a hassle to explain, huh...... Do you know about the double-slit interference experiment? ”

457 had an uncertain look on his face, and his tone was calm and patient, as if he were communicating with a child who was ignorant of the world.

"Double-slit interference experiment......" Zhang Jike was stunned for a moment, and his face showed a look of recollection, "I've heard of it, but it's not very clear, what's wrong?" ”

"Well, it doesn't have much to do with that."

Without waiting for 457 to speak, Wang Yu, who was sitting cross-legged on the ground not far away, quickly added.

"Uh......"

457 and Zhang Jike's heads hung down three black lines at the same time.

Seeing that the two no longer talked, but turned their eyes to themselves, Wang Yu suspended his busy work and added a little helplessly.

"Xiao Hengheng, what's the use of you telling him these complicated things, he is not engaged in scientific research at first glance, and he says something that is easy to understand to save time."

Hearing this, Zhang Jike also nodded and agreed.

Although he was educated, what the young man in front of him was about to describe was clearly beyond his means.

According to the other party's popular science method, not to mention whether he can understand what the 'Elder of the Realm' is, I'm afraid it would be good if he heard it and didn't fall asleep in the end.

After all, he is a soldier, not a scholar engaged in scientific research.

"Well, I'll keep it as simple as I can ......"

The young man also listened to the persuasion and nodded slightly at Wang Yu.

After a moment's thought, 457 spoke again.

"You always know soap bubbles, beautiful things that rely on the surface tension between liquids......"

Zhang Jike nodded, he still knows such a straightforward thing very well, after all, who hasn't played with soap bubbles when he was a child.

"You and I live in the world, huh...... The universe is two different soap bubbles, I'm on soap bubble 457 and you're on soap bubble 22. ”

As he spoke, the young man grabbed his left and right hands, as if pinching two invisible soap bubbles.

"But unlike the usual bubble blowing, these soap bubbles do not exist completely independently, but one after the other, layer upon layer, and never end......"

Watching the young man's left and right hands splicing, forming a ten-fingered ball in front of him, Zhang Jike blurted out: "Matryoshka? ”

"Uh, yes! It's a nesting doll! Layer after layer, never touching, parallel to each other. ”

457 nodded again and again, happy that Zhang Jike had finally kept up with his train of thought.

"Logically speaking, there is no material exchange or even any connection between each differently numbered bubble, but the appearance of the remnant blade changes that."

The hands were released, and there was a sound of the machine bounce in the left arm of 457's machinery, and in Zhang Jike's surprised gaze, the surface of the forearm quickly cracked, revealing an inconspicuous blade.

It is about a foot long, and its whole body is black, as if it has been thrown into a fire and calcined for tens of thousands of years.

"This is called the Remnant Blade."

Zhang Jike became curious, and subconsciously wanted to get closer to see the real thing.

But in the next second, the mechanical arm quickly closed, blocking the view of the middle-aged soldier.

Ignoring the disappointment in Zhang Jike's eyes, 457 continued his explanation.

"This thing can break through the barrier between different 'soap bubbles', and connect two worlds that would otherwise not affect each other."

"So hold this??????????????? The person with the stump is also called the Elder? ”

The middle-aged soldier did not continue to remain silent, but asked a rhetorical question tentatively.

"That's right, but due to the constraints of the timeline, there is usually only one Elder, and that is me."

"How does this thing work......"

Looking down at the young man's mechanical left arm, Zhang Jike seemed to want to take another look at the appearance of the inconspicuous remnant blade, but before he could finish speaking, 457 hurriedly interrupted.

"I won't go into detail about the principle, because I haven't understood it either, the only thing I can tell you is that the energy required for this thing to crack the 'diaphragm' is huge, and there is a very strict time limit."

Zhang Jike was silent, and his sluggish expression showed that his brain was overloaded with something.

After a while, the middle-aged soldier spat out a few obscure words.

Minkowski...... ...... spatial fragmentation effect"

"What? What big truck driver? Boot crushing response? ”

457 raised his eyebrows, obviously not hearing what Zhang Jike was muttering clearly.

"He's talking about the Minkowski Space Fragmentation Effect!"

The beauties in the rear couldn't stand 457's bad hearing, and added a sentence with some impatience.

"You know this?"

After hearing what Wang Yu repeated, the expression on 457's face changed again and again, and finally froze on the strange expression.

"No, I was told too, a man who saved my life not long ago, a man with a similar identity to you......"

457 and Wang Yu glanced at each other and asked in unison, "What's his name?!" ”

"Seventh generation of Guardian Bio-Bio-Humans, codenamed 044, Hamilton."

“？？？”

A big question mark popped up in Zhang Heng and Wang Yu's minds.

Where did this god come from? I've never heard of such a person......

457 scratched his head and cast an inquiring glance at Wang Yu behind him.

The latter shrugged his shoulders and refocused his attention on the flask in his hand, while dropping a very irresponsible word.

"Don't look at me, he said that it is the seventh generation of guard-type biochemical androids, it is definitely impossible to come from the 659th timeline, although the technology tree there is a little crooked, but on the whole it is still on the right track, and it is impossible to point out the high-energy consumption and easy self-destruction technology of intelligent machines."

"But I didn't point out this technology on my timeline, Guardian Biocyborg, isn't that a fucking Terminator?!"

457 looked confused, and suddenly the image of a muscular man dual-wielding Gatling flashing wildly and shouting that I would be back suddenly appeared in his mind.

"Yes, I also feel like a Terminator......" Zhang Jike blinked, a little strange that there was also this kind of muscle popcorn movie in another world.

But he didn't let this distract him, and continued.

"Hamilton says he came here through the Minkowski Space Breaker for one purpose, to protect the girls around him."

"What a cliché ......" 457 frowned, looking at Zhang Jike in front of him with a very exaggerated and confused expression, as if what the other party had just said was not the truth, but a fabricated story.

"What's that girl's name?" Wang Yu seemed to have selected the right potion, and was about to crush it in the palm of his hand, when he heard Zhang Jike's words, he interjected at random.

“??????????????? I don't know. Without hesitation, the middle-aged soldier chose to tell a little lie here, after all, he still didn't know what the position of the men and women on the other side was.

Hamilton was only thrown out before for a better exchange of information, and as for a powerless girl like Sun Jiayi, it would be better to keep it as secret as possible.

"That's it, it doesn't matter, I guess it was sent by the timeline that has advanced technology but failed to give birth to the Elder, but for Mao is to protect the girl, if the protection target is changed, maybe I can talk to him......"

Although 457 and Wang Yu had no intention of continuing to ask, their self-talk still aroused Zhang Jike's vigilance.

The two people on the opposite side seem to have a hostile relationship with the old man!

Thinking of this, Zhang Jike's slightly relaxed vigilance once again mentioned his throat.

It doesn't matter if he's dead, but it's not good if he touches his former life-saver.

Not noticing the change in the look in the middle-aged soldier's eyes, 457 turned his head and continued in a tone of statement and inquiry.

"So you weren't surprised to see the two of us before, and most of the reason for that was because you had already met that cyborg named Hamilton, right?"

Zhang Jike nodded, and after a while, he added thoughtfully.

"He's strong and has weapons far beyond his time......"

The reason why I added such a sentence was not because Zhang Jike was curious about Hamilton's technology, but mainly because he wanted to use this to knock the men and women in front of him-

The Terminator called Hamilton has a horse in his mouth, and you must not have the idea of fighting against it!

If the men and women on the other side are flexible, they must know the stakes and will not easily think about provoking Hamilton, so Sun Jiayi's safety will have an extra layer of protection.

But to Zhang Jike's surprise, after listening to his 'kind words and persuasion', Zhang Heng and Wang Yu did not have much surprise on their faces, but showed a look of course.

"Listening to your previous description, Hamilton is probably also from another timeline, if you don't have some skills, how can you protect the target?"

With that, the woman's right hand was forced, and she smashed a potion bottle with a click.

Zhang Jike, who looked at the simple movements, frowned, because he noticed that the glass slag of the medicine bottle was also embedded in the woman's palm, and the blood was mixed with the liquid medicine, and it was falling to the ground dripping......
