"I'll be careful in my choice." Barry clearly doesn't fully understand the implications of changing the past, or rather, he's been so preoccupied with saving his family that he chooses not to think about the impact of changing the past.

"I hope so." Li Zhen closed his eyes and sighed.

After this, Barry had a conversation with Joe, Iris, and his father, who was far away in prison. When he returned to the cutting-edge lab, he had clearly made up his mind.

Cutting-edge labs, superpower prisons.

"Wow, you're thinking about it for a full hour longer than I thought." Reverse Lightning saw Barry who came alone, and greeted him with a smile. Obviously, things didn't go beyond his expectations.

"So, what should you do with your grand plan?" Barry didn't want to talk to him too much.

"It's not grandiose, it's simple, Barry. We use a particle accelerator, and unlike before, we don't need to use two particles in the opposite direction to move in the inner circle and hit each other at the speed of light; We just need to inject one particle! Reverse Lightning explained with a confident smile.

As if enlightened, Barry suddenly understood, "And I'm going to collide with that particle!" ”

"That's right, Barry. If you can run fast enough, if you can hit that pellet with enough speed, you can make a hole in the objective world! This hole will be the portal that connects the point in time we are in and the wireless time! "The reverse lightning narrator of his grand plan:

"Through the portal, you can go back in time. Like going back to the night your mother died, or traveling back in time to the future! Like, my time! ”

Barry sorted out the information in his mind and said hesitantly, "What if yours is based on me running fast enough, what if I don't run fast enough?" ”

"If you don't meet the expected speed barrier, you're going to die." Reverse Lightning said the answer without care.

In the council hall, Barry tells everyone about his choice. Although the crowd did not agree with it, they still respected Barry's choice. Only Li Zhen quietly walked to the roof of the building. Yuan Hong was the only one who noticed Li Zhen's exit, standing behind Li Zhen and watching Li Zhen take out a cigarette and breathe.

"Master, is there anything bothering?"

"Oh, little Yuan Hong." Li Zhen didn't notice Yuan Hong's approach at all, and reacted after a moment. "Nothing, just a little irritable."

"Do you need me to stop the Flash's plan?" Yuan Hong flashed his sharp claws.

Li Zhen was stunned for a moment, shook his head and smiled bitterly: "Is it so obvious that I behaved?" ”

"No, master. Don't forget I'm your pet! I don't know what you're thinking, but I can feel the fear of the unknown in you. Yuan Hong explained.

"You're right, my heart is filled with fear of the unknown. I'm not sure if Barry would be able to become an angel if he changed his past. Li Zhen looked at the starry sky, his eyes full of confusion.

"I can't let go of the identity and power of an angel anymore, I can't imagine that if I lose the power of an angel, then what can I do to protect myself in this fucking world!"

"I'm going to kill the Flash right now!" Yuan Hong felt the fear in Li Zhen's heart, and turned his head viciously to see Barry.

"Forget it, Yuan Hong. Let me take a gamble! With everything I have right now, bet on whether Barry deserves to be called the 'conscience of the Justice League'! Li Zhen stomped on the cigarette butt and stopped Yuan Hong.

In fact, Li Zhen also made a decision through careful consideration, after all, even if he stopped the Flash this time, he still has a chance to change the past in the future. At least this time, because of Barry's biological father's teachings, there is still a good chance that the Flash has not changed the past. If something goes wrong because of Li Zhen himself, then this world!

Li Zhen thought of the apocalyptic scene in the animated movie "Justice League: Lightning", and couldn't help but shudder.

"However, even if I don't stop it, I'll arrange something in advance." Li Zhen made a decision in his eyes, and the sudden coldness he showed made Yuan Hong tremble.

When everything was ready, the group regrouped outside the Prison Gate for the Superpowers.

"Maybe it's the last time we'll be together. Barry, I wish you happiness. Caitlin gave Barry a sensual hug.

"Maybe we'll be as a team in the new world as we are now." Barry comforts Caitlyn.

"Barry." Li Zhen stepped forward and hugged Barry, patted Barry on the back fiercely, and said, "I hope there are not so many sins and disasters in the new world." ”

"I'm sure Kyle will always be there for those in need in that world!" Barry also sighed with emotion.

After the reluctant goodbye of the crowd, Sisko stepped forward and said a final admonition: "Well, there are three of you there, the future you, the young you who was saved from the reverse lightning, and the current you. Be sure to remember! You can't save your mother until you rescue the young you in the future! ”

"I'll remember." Barry nodded solemnly.

"May the speed force be with you." Sisko gave a blessing.

"Why don't you want me to be with him?" Li Zhen made a joke and livened up the atmosphere.

"OK, I'm going!" Barry puts on the Flash's tight-fitting suit and opens the prison doors.

"The future of both of us is in your hands, Barry. I know you can do it, now, run, Flash! Reverse Lightning walked out of the door and stepped aside.
