It's just that I saw this starry sky again, and the cactus felt extremely missed, although only three days had passed for Zuo Zuobu, but for the cactus, it was more than two thousand years of time that had passed, and it stayed at one end of history for a while, and then it returned to the present time.

The cactus passed through the thousand-meter-high iris of the time wormhole machine, and then his friends walked out one by one, and just as the cactus turned his head to count the number of people, he found that there was one missing.

And this person happens to be a pebble that hasn't been seen for a long time. The cactus was suddenly in a low mood, it was a huge blow, and even anger burned in his heart, and he looked at Zuo Zuobu, who was sleeping on the side.

Zuo Zuobu was sleeping soundly, and he didn't care about the arrival of the cactus and his party, but at this time, the cactus's heart was already very sad, if something really happened to the pebbles, Zuo Zuobu's life would be a little worrying.

But Zuo Zuobu soon woke up from his hazy sleep, and he opened his wistful eyes to look at the time-traveling travelers in front of him, ready to celebrate a little for their successful return.

But Zuo Zuobu felt that the atmosphere was obviously wrong, so he looked at the cactus.

The cactus's heart was already full of anger, but it was not to the point of killing, but he looked at Zuo Zuobu with a little anger and asked, "When we came back, there was one less person, what do you say?" ”

Zuo Zuobu was originally a very careful scientist, and when he usually studied and experimented, he would not make a mistake, but now he heard that there was one less person, and his heart suddenly stirred up a big wave, and even the sweat on his face fell a little, but Zuo Zuobu couldn't wipe the sweat, so he could only let the sweat flow on his cheeks, and he felt very uncomfortable.

But Zuo Zuobu still gave a solution, saying: "It doesn't matter, I have experimented with this machine nearly hundreds of millions of times, and I know all the control information well." Let's do this, cactus, I can now directly find the missing person, because the second I enter the gate of time, everyone's physiological information and consciousness information have been recorded in it by my machine, since this person has not reached this iris, that is, has not reached the current place, then this missed person can be easily found. So, no problem, I'm in control, you just have to wait a while! ”

After hearing this, although the cactus did not have all the anger in his heart, he wanted to protect the pebble after all, but now all the means that can grasp the information about the disappearance of the pebble are all in the hands of Zuo Zuobu, so he also believes in him again.

Zuo Zuobu immediately inserted tablets into the outer armor of his huge time wormhole machine, and those tablets displayed all kinds of incomprehensible information, but Zuo Zuobu was very engrossed, so that the cactus and his five friends couldn't do anything on the side, so they could only wait.

After a while, Zuo Zuobu returned to reality from his working state, and called the cactus standing on the side to pass.

The cactus was not very patient in the first place, but after seeing Zuo Zuobu calling him, he immediately flew over. Around this time wormhole, the pale blue light stretched far away, illuminating several people under it, but the universe was very dark, and the cactus could only observe the surrounding things through the light.

"Look, is she the one you lost?" Zuo Zuobu said, pointing to the image in one of the tablets.

From there, the cactus saw a woman flying to the other gate where they had returned, before the two gates of time, but he could clearly see that they were pebbles, so he nodded at Zuo Zuobu.

Zuo Zuobu touched his chin and said, "The reason why this person didn't come back is not because my machine was wrong, but because I did something wrong." ”

The cactus looked at Zuo Zubuu inexplicably and said, "What did you do wrong?" Could it be that you did it on purpose? ”

Zuo Zuobu said remorsefully: "It may be that I pressed a button when I was napping just now, and the function of this case is to teleport an individual in the time wormhole to the other side of time. But right now, I'm using all the computers in this machine to quickly calculate how this girl, your Miss Pebblestone, has been teleported to that stage of history. ”

Although the cactus could understand some of the key terms, he was still very worried about the safety of the pebbles, so he could only wait for the results of the machine in front of them.

Time passed very slowly at this time, and the cactus was extremely anxious, but he thought that as long as he could search for the time and place of the pebble crossing, he would definitely be able to find her again through this huge time wormhole machine.

Time passed minute by minute, and Zuo Zuobu's quantum computers were carrying out extremely complex calculations, and when the cactus was about to lose patience, they waited for Zuo Zuobu's reply.

"Unfortunately, cactus, something very, very interesting happened to our pebbles." Zuo Zuobu said with a slight smile.

The cactus was very puzzled and asked directly, "What is a very interesting thing?" Could it be that she is fine? ”

Zuo Zuobu nodded and said, "Yes, she has been transported to the future of the Earth Era in 33333 AD, and it has been thirty-three years since now. ”

After hearing this, Zuo Zubu's voice was transmitted by a loudspeaker in the helmet on his spacesuit through a specific electromagnetic wave. The flesh of these heavenly warriors could understand the way this sound was transmitted, so everyone gathered together, not understanding what Zuo Zuobu was talking about.

"Traveling to the future, how can this kind of thing happen, this is completely contrary to the laws of physics!" The cactus shouted.

Hearing this, Zuo Zuobu touched his head in embarrassment and replied: "Actually, this big machine of mine originally did not have this ability, because once the people of the current era travel to the future era, I am really uncertain about the impact, so generally speaking, it is more stable to travel to the past." But to be sure, in fact, this kind of time machine is a special existence in this world, to put it bluntly, I only got this kind of technique, and I started to do experiments, as for the core principle, I have been a doctor of physics for many years can't understand it. ”

The cactus sighed, not blaming him, and said, "Since the core of this technique is not in your hands, you can still build this machine, as if you have a blueprint to make a product." However, "

Halfway through the cactus's words, he changed the topic and explained his intentions to Zuo Zuobu, "I'm going to go to that era, can you do it?" ”

Half-ringing, Zuo Zuobu didn't react at all, thinking that he was thinking about something, but after less than a few minutes, he reacted, and then affirmed his conjecture, and said: "It's no problem to send you over, but there is a problem, I'll just say it." That is, as soon as you discover that there is your essence in the future, immediately notify me now and send you back, otherwise the consequences will be unimaginable to you, we, and we. ”

The cactus seemed to understand what he meant and said, "If there are two mes in the future, then the world is not chaotic. But there is another situation, which may be more optimistic, and that is that there is no me in the world in the future, right? ”

Zuo Zuobu was glad that the cactus could understand him so quickly, and said, "By the way, this is the only hope that you can go to the future, because once there are two cacti in the future realm, you will kill each other. ”

The cactus nodded in agreement, but he thought of a way to quickly and effectively find a solution to this contradiction, so he asked Zuo Zuobu, "Is there anything you can do in this world to directly find another little machine of mine?" I mean, if once we're in the future, is there a machine that can directly scan the whole world where there might be another self, another cactus? ”

Zuo Zuobu scratched his head through the helmet and said: "I have been preparing this thing for a long time, since the mysterious scientist gave me the blueprint for making this machine, it seems that everything is ready, as long as I understand the technical structure of the period, I can develop it myself, everything is a matter of course, it seems that it is specially prepared for me." ”

"It's just that I'm scared when I think about it now, but God knows what kind of person this is. Well, I don't want this anymore. Back to the topic, the small machine you want is actually a necessary accessory for this space-time wormhole, whether it is to go back to the past or to the future, it must be prepared, and it is already on you. Zuo Zuobu said seriously.

"Oh? Isn't it, when did you put it on me? The cactus asked, bewildered.

Zuo Zuobu stepped forward, took a smartphone-like thing out of the cactus's pocket, shook it in front of him, and said: "That's it, this machine is called 'Time Invisibility Cloak', not only can it make time travelers communicate with the time machine at any time, but it also has another function is that once the situation we just guessed occurs, it will immediately block one of the two main objects in the same time world. ”

The cactus had read a little philosophy book before, and he could clearly understand Zuo Zuobu's blunt philosophical explanation, saying: "No wonder I went back to that year, when I was back in that year, the original me, that is, the original cactus, once I didn't discover my existence, it turned out that my existence was blocked by this time invisibility cloak." ”

Zuo Zuobu nodded happily and said, "Although I don't understand the main core principle, I know that this is a quantum mechanical technology. ”

After saying that, he shrugged his shoulders, indicating that he still hadn't figured out the essence of this thing.
