After confirming that Mentor Red had really left this time, soon, the three of Yi Cheng, who had ugly faces, came to the time machine again.

"This time it's a big deal......"

Looking at the wreckage of the machine that was still smoking pungent smoke and the arc crackling, the corners of Yi Cheng's mouth twitched slightly.

"That, Bai Ze."

"Well, what's wrong?"

"We're going through the time tunnel, and it's all about relying on this time machine."

"Well, that's right in theory."

"That, Mediator."

"What's the matter, section chief?"

"Did Mentor Red say that if the time machine breaks, how do we go back?"

"This ...... It doesn't seem to be. ”

“……”

After a brief confirmation, Yi Cheng also understood a terrible truth.

"We ...... Can't go back? ”

Trapped in this past...... In a timeline where the time machine has been corrupted, there is no way to go back to your own time?

"Wait...... My mind seems to be a little messy. ”

Yi Cheng grabbed his hair hard, forcing himself into a state of absolute rational thinking.

However, after thinking about it, this is the only conclusion that I finally came to this one.

"So, what the hell is going on!"

Then, his angry roar echoed through the empty underground warehouse.

"Hey! Be quiet! Although the sound insulation of this underground warehouse is very good, it would be terrible if it was discovered! ”

Bai Ze tried to stop Yi Cheng's irritable behavior, but instead gave him a wake-up call.

"That's right! Let's just go straight to that red mentor and have a showdown with her! For the sake of her future subordinates, she will definitely help us fix this machine! ”

"That's impossible."

Bai Ze shook his head and vetoed Yi Cheng's "proposal".

"If we go to the Red Mentor now, then we will create a history that does not exist in the long river of time, and thus affect the future branches."

"But...... That's right! According to what you said, maybe this is what history is supposed to be! ”

"Suppose there is such a possibility as you say...... However, it is better not to do that lightly than the danger beyond the possibility. ”

"Dangerous?"

"Hmm."

The mediator Ji An nodded, affirming Bai Ze's statement.

"This kind of communication with people we know in the past is the most likely to create timeline constraints, so let's not do that."

“……”

The situation became an impasse for a moment, and all three fell into an unspeakable silence.

After all, no one ...... the fact that the time machine at this time will explode and damage

"Wait."

Yi Cheng suddenly remembered something.

"If it's the woman of the Red Mentor...... How could she not know that her own thing had exploded at this time! ”

"Maybe you forgot?"

"Absolutely not!"

Regarding the possibility proposed by Bai Ze, Yi Cheng rarely denied it with the guarantee of Mentor Hong's festival operation.

"You see, the explosion just now and the expression on the woman's face when she crossed back twice, in the process, something unknown must have happened, and even if nothing major happened, this explosion alone will definitely make people remember it for more than ten years."

"You mean ......"

The mediator, Ji An, also understood.

"Director Hong, she did it on purpose...... Let's choose which one to arrive at this time? ”

"Coincidence or purpose, now we can only believe that the woman has a way to get us back."

Yi Cheng sighed and shook his head.

"So, we're now

It's better to find a way to complete this task first - maybe the woman is using this as a threat. ”

Broken cauldron or something...... Xiang Yu used it once, yes, but who can say that it wasn't the biggest flag he put up for his life?

So now, when he was in the same situation, Yi Cheng also felt a chill from the heart.

"This time's mission...... Looks like it's going to be a lot of trouble. ”

Unconsciously erected such a flag, and then, the three people who could only put aside the fact that the back road was cut off for the time being, walked towards the outside of the underground warehouse.

"Huh? I can't seem to open the door of the warehouse......"

After all, it was the red mentor technology more than ten years ago, and at this time, the access control equipment as artificial intelligence had not yet been put into use, and it was a mechanical password lock device that looked quite ancient that controlled the opening and closing of the entire warehouse door.

"Mentor Hong once said that any intelligent encryption and network encryption have the possibility of being cracked, and only mechanical passwords are the most secure ......"

The mediator looked at the password panel with some embarrassment: "Enter it three times and it will be poom!!" The crappy font of ", and then turned his eyes to Yi Cheng and Bai Ze for help.

"This ...... Does any of you know the password? ”

"Speaking of passwords......

Bai Ze looked at Yi Cheng thoughtfully.

"Maybe the protagonist will know."

"I know, I know, but I ......"

Yi Cheng smiled, shook his head, walked to the password panel, and casually entered the four-digit number.

"Buzz ......"

When the warehouse door opened, Yi Cheng did not forget to remind the two companions.

"I don't have a leg with that woman, and this number is nothing special - I just happened to hear Mentor Red muttering the password by himself."

“……”

Bai Ze and the mediator glanced at each other, and then hurried to follow Yi Cheng.

Out of the underground warehouse, the small building of the Savior's Management Office still stands in the courtyard as always—the difference is that the current building looks a little older than it did more than a decade later...... That's right, this is probably because the building itself has been remade an unknown number of times in the past ten years to produce such an effect.

Of course, the three of them didn't have the heart to study this problem now, and they quickly slipped out of the gate against the wall and came to the street at the door, which was a sigh of relief.

"It's out...... So now, what do we do? ”

While glad that the Savior's management office itself did not have a strict curfew, Yi Cheng turned his inquiring eyes to the mediator.

"Hmm...... Next, we have to find a way to get to the vicinity of the Olympic bid venue – if it's sabotage, then directly interfering with the results of the vote couldn't be easier. ”

"That'...... Where is that venue located? ”

Yi Cheng, who naively thought that "since it is the imperial capital bidding for the Olympic Games, the venue is in the imperial capital", he was hit by Bai Ze next.

"The bid meeting for this Olympic Games was held in Moscow, the capital of the woolly bear country, so we had to find a way to catch a flight to Moscow first."

“…… What? ”

Yi Cheng, who was stunned for a long time before he understood what Bai Ze meant, blew up at that time.

"What a joke! The three of us didn't even have ID cards at this time! How do you get on a plane? ”

In fact, Yi Cheng originally wanted to say that "it's not even a fertilized egg", but after careful calculation, he himself was probably in junior high school at this time, and the age of Bai Ze and the mediator was obviously born in the post-90s and even post-80s before the battle of the century, so this statement is indeed a little exaggerated.

Bai Ze's response to this was very simple.

"As a savior, if you can't even solve this little trouble, that's a joke."

So, 20 minutes later, the imperial capital airport.

"This is a boarding pass for three people, please take it."

“……”

Looking at the smiling ticket sales lady handed over the ticket, again

Looking at the large number of ordinary people lined up behind him, Yi Cheng was truly stunned this time.

"This ...... Is it really okay to do that? ”

"As a member of the Aftercare Division, it's okay to take advantage of your position a little if necessary."

"That's not what I'm talking about!"

Yi Cheng pointed to the large ticket of ordinary people and the ticket lady who had been cleaned of their memories by using a simple small amnestic device.

"The point of such a large-scale amnestic is that we are still in the past, this kind of behavior...... Wouldn't it cause an anomaly in the timeline? ”

"So, I told you from the beginning that the closure of the timeline will only take effect for certain situations."

Bai Ze shook his head and glanced at the innocent citizens.

"And these people, although they have lost a small memory of us, but in fact, even if we don't do this, whether we return to the future after the mission is successful, or we are erased by the timeline after the mission fails, the part of these people's memories about us will naturally disappear, or become other irrelevant people, so ...... It's not really a big deal. ”

"Wait......"

Although what Bai Ze said seemed to be an understatement, Yi Cheng finally grasped the point.

"What do you mean...... Will we be erased by the timeline when the mission fails? ”

"This ...... Let me explain. ”

The mediator, who had just run to the vending machine to buy hot coffee and milk tea, handed one of the cups to Yi Cheng, who was at a loss.

"There's a famous saying that 'no two leaves are exactly the same on a tree,' and I don't know if you've ever heard of it."

"Hmm...... I've heard it, I've heard it, but what does this have to do with the topic we're talking about now? ”

"Well, then simply change the object and the place, and the phrase becomes 'There are no two identical stones in a river'......"

The mediator glanced at Yi Cheng with a deep look in his eyes.

"So, section chief, do you understand what it means?"

"Uh......"

Yi Cheng is not stupid, in fact, everyone has always used "river" as an example when it comes to the behavior of time travel and related matters, so now, when the mediator changes his words, he immediately understands the meaning of this sentence.

In the long river of time, there are absolutely no two identical individuals, and in fact, the three people who have now traveled back to the past from the future are tantamount to violating such a rule.

Although in a sense, Yi Cheng when he was a child and the current "protagonist" Yi Cheng are not the same individual, but in the cognition of the long river of time, this is just the "past" and "present" of a stone, so when the timeline is closed, there will only be one stone left, and another stone that should not exist in theory will disappear under the washing of the river.

"So, you get the idea."

Bai Ze, who blew and drank a few sips of coffee, summed up the above content in a calm tone.

"That's what I said about the 'dangers that the timeline may bring' that it may bring."
