Faced with Zhang Tianran's on-site teaching, Barry Allen did not study at all, and directly untied Martin Stein's constraints, and did not use the power of speed.

"Hey... Forget it, you guy suffer a lot and you will probably have a better memory." Seeing this scene, Zhang Tianran completely lost interest in continuing to teach.

"Barry, take Professor Stein first. I still have some aftermath work to deal with." Since I didn't plan to teach again, Zhang Tianran spoke and sent Barry away.

When Barry heard this, he nodded. He immediately carried Martin Stein and left without any delay.

After Barry completely disappeared, Zhang Tianran then started to enter the extreme speed state. Now he stored the remaining Barry's speed power in his body for future research.

Later, I went to the archives in this military base to see if there were any things I was interested in.

Generally speaking, military supplies are several levels higher than civilian technology. But in this world, this gap does not seem to be that obvious.

I found some interesting toys, but didn't get much. Zhang Tianran left in a little disappointed manner and did not kill anyone.

Although he would not let it go if he didn't kill this so-called General Ailin. However, killing it will not be of much benefit, but it will cause some trouble instead.

So, whatever. Although the military in this world has some strength, it is actually not very important.

...

Barry brought Martin Stein back to Star Laboratory, and Caitlin immediately began to deal with his wounds.

Although the military's torture was only half done, this was still a serious burden for an old man, even now Martin Stein is not just himself.

While Martin Stein was treating the wound, Zhang Tianran said:

"I found a potion that temporarily suppresses your abilities, but there is no way to completely eliminate your supernatural abilities."

"However, according to my calculations, you two can actually separate now, but you only need to merge again and inject the potion I made."

Upon hearing this, Martin Stein and Ronnie Raymond's faces suddenly showed joy.

If possible, these people don't actually want to become superpowers.

"Really? Can Ronnie be restored to normal state?" Caitlin said in disbelief.

Zhang Tianran shook his head and explained:

"No, I just said that you can separate completely and hide your supernatural abilities for a short time. As for the original changes, they will not disappear. If you want, you can transform into a fire storm at any time, but at that time you will need some equipment to assist you."

Just when Caitlin was a little disappointed, Zhang Tianran said again:

"Although the physical changes cannot disappear, there is no problem if you want to live a normal life. After all, you two can only become a fire storm together."

Martin Stein seemed to finally understand what Zhang Tianran said and said, "You mean that our bodies cannot disappear through the changes caused by the explosion of particle accelerator, but can we be completely separated, right?"

"Well, that's it..."

In the end, Martin Stein and Ronnie Raymond chose to separate completely. As for whether to continue living as Fire Storm in the future, the two of them have not yet decided.

After all, there are already government troops targeting them, and it is no longer that simple to live a normal life.

...

Everything seemed to be trapped in a dull daily life again.

Zhang Tianran continued to work hard in the renovated private laboratory, while Barry and others were paying attention to the entire central city, catching thieves from time to time and saving the trapped people in the fire.

More than a week passed in a flash. Just as Zhang Tianran was a little confused about why the change mentioned by Flash had not yet arrived, everything happened so suddenly.

As usual, Zhang Tianran stayed in a private laboratory to make some small toys, and then Caitlyn's voice came from the emergency channel.

"Dr. Zhang, Barry needs help..."

But the next moment, everything around him stopped, just like when Zhang Tianran was using the speed power.

However, at this moment, Zhang Tianran was very sure that he did not use any speed power.

Soon, everything that was still began to flow, but this time it was not continuing, but retreating...

Soon, the rapid retreat time completely shattered everything, and Zhang Tianran was like a person forgotten by time, watching everything disappear and then change into another way.

This is... the timeline change.

Turning into a white lightning, Zhang Tianran immediately found Barry Allen. Even though he had already made some predictions in his heart, he still asked: "Barry, what did you do?"

"Dr. Zhang, I...I don't know. I was still stopping the tsunami from destroying the central city just now, but now..." Barry subconsciously glanced at the dark street, extremely confused.

"Barry, what happened? I saw you stop..." Sisco's voice came from the communicator, which made Barry even more confused.

"Stop? I'm going there?" Barry suddenly became even more confused about what was going on.

"Go to the morgue, aren't you going to check the crime scene?" Sisco was a little confused.

"Didn't I go there yesterday? Why now..." Before Barry could finish his words, Zhang Tianran directly pulled him into the extreme speed state.

"Dr. Zhang..." Barry was pulled into this state by others for the first time, and he was a little uncomfortable.

"Barry, listen carefully to me. I don't know what you encountered, but obviously you crossed the timeline, or... it's not an ordinary time travel, but you're backing the time to last night."

Zhang Tianran didn't care about understanding what he had just encountered, and immediately spoke to Barry Allen: "Remember, start now. Don't change anything. Even if you know everything, you must do what happened yesterday."

"Don't play with time, any idea of ​​trying to change the timeline will suffer a bigger tragedy."

"Forget it, I guess you won't listen. But this is an experience, remember this experience, and then... never try to change the past."

Although he knew that Barry was most likely not to listen, Zhang Tianran warned him, and then turned into a white lightning and disappeared directly.

"Willes, I have something to look for you." After returning to Xingchen Laboratory, Zhang Tianran immediately found the Flash sitting in the wheelchair with a pale face.
