Earth One Timeline: Half a year ago.

Location: Midtown.

Date: Saturday.

Time: 11:05 a.m.

After Barry finished talking to Wang Quan about Caitlin's emergency call for help from the communicator, there was Barry Allen three days later, and Barry came to Midtown in the current timeline three days later.

Wang Quan just narrowed his eyes slightly, looking at Barry Allen's expression a little shocked, panicked, and didn't know what to do.

Wang Quan immediately understood.

Time travel!

Time travel for sure!

Illustrates that three days later, Barry Allen has mastered time and traveled through time to return to the present.

"I see what you mean! Barry! That is to say, three days later, you have traveled back to the present, and you are in the past tense at this moment! That's it! Wang Quan is sure that this is the case, yes.

"That's right! That's what I mean, but you're coming along, I heard your voice in the communicator just now, and it must have been you and me coming together three days later! I don't know why! Barry nodded hurriedly in agreement.

Wang Quan heard that he was not much surprised that he would travel three days later, Wang Quan had suspected a long time ago that the speed force in his brain was connected to Barry Allen, and it was very likely that it was used for this purpose, and now it has finally been confirmed.

Wang Quan is thinking about the consequences of the matter, the importance of the matter.

At this time, Barry Allen couldn't wait to look at Wang Quan and said, "Why don't we go to the scene now?" Barry was eager to see why they had crossed back.

As soon as Barry finished speaking, he was sternly stopped by Wang Quan: "Absolutely can't go!" We must not see our future selves, nor can we see our past selves, which will produce a ripple reaction, which is the butterfly effect! We should avoid contact with them now and watch when they will leave, if they stay longer...... The consequences are absolutely unimaginable! ”

Barry swallowed his saliva, and when he heard what Wang Quan said, things really didn't seem to be that simple, and Barry continued to ask in a panic: "What will be the consequences?" ”

At this point, Wang Quan lowered his head and said in a panic: "It is very likely that we will be replaced by ourselves in three days, and it is also very likely that we will open up a unique timeline, and the specific me... I... I do not know... I'm sorry! Barry I don't know, I'm completely unsure! ”

Barry looked at such a helpless Wang Quan, and he was also stunned and puzzled for a moment, and hurriedly asked, "What's wrong!" Woof! What's going on? ”

"I've sensed you in the forest south of the city, where Barry Allen is battling Mark Madden three days later, and you've got the upper hand... At the same time, I also telepathically sensed myself three days after the cutting-edge technology laboratory, and he also ......" Speaking of this, Wang Quan paused, his expression seemed a little panicked, and he was also at a loss, and at the same time felt very sudden.

When Barry saw Wang Quan's appearance, he was also frightened, and a catastrophe was coming?

Barry immediately supported Wang Quan's shoulders with both hands, and said anxiously: "Don't do this! Wang Quan! Don't scare me! You really scared me, you've never panicked like this! You've been calm before! What the hell is wrong with you now! What problems can we solve together! ”

Wang Quan took a deep breath and regained his expression: "I'm OK!" ”

Seeing this, Barry eased up slightly, Wang Quan just now really scared Barry, thinking that something bad would happen!

"Barry! I'll go out for a while, don't wait for me! Wang Quan solemnized his expression again and admonished.

After Wang Quan finished speaking, without waiting for Barry to continue talking, he immediately turned into a black lightning bolt and left Barry's old house.

Seeing this, Barry suddenly felt that something was wrong, and he also turned into yellow lightning flashes and chased out.

But when Barry rolled up a yellow arc and flashed out, Wang Quan was never seen again.

After searching a few streets again.

Bari stopped his pace and looked at the lively neighborhood with people coming and going, the sound of cars, and all kinds of people, but he didn't find any trace of Wang Quan.

Barry's search was fruitless, so he could only give up, and listened to Wang Quan say that three days later, he and Wang Quan both came over to their own timeline.

Wang Quan also said just now that there are serious consequences, you can't meet, you can't intervene, and you can't have any interaction, that is to say, Mark Madden in the forest in the south of the city has no half-dime relationship with his current self, and now he is an outsider.

Barry didn't mind the outsiders, but he was puzzled by what Wang Quan's last sentence in the old house just now meant.

Barry had to go back to the old house again, and the cutting-edge technology lab couldn't go back anyway.

Inside, he grabbed a bottle of beer and sat on an old-fashioned couch, facing the warm sun outside the window.

At the same time, in the lobby of the cutting-edge technology laboratory.

"Barry, we need to talk, you and I come here." Wang Quan walked into the treadmill room where Sisko had been placed.

In the midst of the other people's questions, Barry followed Wang Quan into the treadmill room.

"We crossed? Back to three days ago? Right? Barry asked excitedly.

Wang Quan nodded: "Yes!" The speed force has connected you to me, and I have been carried by you through time. ”

Barry clenched his fists when he heard the definite answer, and said excitedly, "Great! That way I can save their lives on the cruise ship, Joe won't be threatened with being taken away, and I won't have to be hurt by anyone else's life than if I had no choice. ”

"That's great!" Barry breathed a deep sigh of relief, not having to face that damn choice, everything could change now, and Joe wasn't captured.

"Barry, time is an extremely fragile structural system, no matter how small the deviation, it can cause a huge disaster, once you decide to save the few people on the cruise ship, who have already died, it may lead to an even greater disaster, you have to be mentally prepared." Wang Quan said solemnly, whether it has changed or not in the past three days, Wang Quan feels that it doesn't matter, as long as everyone in the cutting-edge science and technology laboratory is okay and not harmed.

"You mean I don't want to save them? Wang Quan, you weren't on the cruise ship at the time! You don't know how cruel it must be, and I can't let this happen again. Barry looked firm.

"I don't mean to stop you, I'm just telling you to be mentally prepared, what happens next is the result of changing the course of history." Wang Quan lit a cigarette and said seriously.

The two talked a few more words, after Barry left.

Wang Quan's eyes narrowed slightly, and he became serious, Wang Quan deeply understood this truth, there can be no two identical people in the same timeline, the butterfly effect is small, the replacement of the original body is small, the timeline will collapse is big, the timeline will be confused is big, and the consequences of the timeline will be unimaginable is the most important thing.

Wang Quan had already made his decision, and he traveled out of the cutting-edge technology laboratory without anyone noticing, including Barry Allen, who traveled back with him to three days ago.
