Barry Allen is slowly standing on a huge, extended treadmill, with his body lying down, ready to sprint.

"I want to remind you that this is a very risky move and will cause a lot of unknown consequences. Your task is to find Downey half a year ago, don't do extra things, remember! I think you know the terrible butterfly effect, Don't do unnecessary things!"

Dr. Harrison pushed his glasses, his expression serious.

The cosmic treadmill is a machine that Harrison built by following the original historical trajectory and was restored by Barry Allen. It was originally used as an aid to travel back to his own time.

But now I have to take it out and give it to Barry first, which is a very bad behavior.

"Don't worry, Doctor, when we made this treadmill together, you made it clear."

Barry nodded heavily, tightened the red hood that he always wore on his head, stepped forward, turned his head to look at the heroes around him who were looking forward to watching him, and then slowly posed a strong red arc across his eyes. .

Buzzing...

Barry ran in small steps, getting faster and faster, gradually surpassing the speed of normal people, and was still increasing her speed crazily.

"A hundred times the speed of sound."

"Two hundred times..."

"Five hundred times..."

"A thousand times! He is so fast, I can't see him clearly!"

Sisko was operating in front of the instrument, watching Barry's speed constant at a thousand times the speed of sound.

On the cosmic treadmill at this time, Barry ran wildly, and the whole person burst out terrible red arcs. These arcs flashed at an alarming frequency, and more and more, gradually covering Barry's body.

The power of the speed force was used by Barry, transformed into a massive red arc, in the huge thunder, like the projection of the gods.

The terrifying and violent power caused the surrounding crowd to retreat continuously, and the entire ground began to tremble. A huge crack cracked from the ground under the treadmill and spread in all directions.

The rapid increase in speed turned Barry's running action into afterimages, which superimposed on the afterimages, making the running Barry blurred.

"It's now! Barry, open the channel! Look for your goal and feel the speed of the force to guide you. You must be accurately positioned until half a year ago! This is the choice you insist on, then stick to it!"

Harrison yelled!

boom!

Barry's figure gradually became blurred. In front of the treadmill, a huge vortex tunnel opened, blooming with an ominous blue color, and a deep black color flashed at the center of the gap, slowly converging into a ball.

Until a loud noise came, accompanied by a huge red electric arc explosion, a large number of objects were lifted off, Barry's figure disappeared completely, and the vortex also lost the support of the rapid force and quickly closed.

There is an unpleasant smell around the cosmic treadmill, which is the burning smell produced by a lot of air friction.

"He succeeded?" Tony looked at the disappearing runner in red in astonishment.

Harrison took off his glasses and wiped them, then calmly said, "He will succeed."

In his heart, Harrison sneered and said, "It's strange."

At the same time in the original Australian area, Steppenwolf looked up in one direction, his face cold and sarcasm.

"The Flash... Shuttle the timeline? Smart and stupid guy."

The moment Barry Allen entered the space-time tunnel, countless noises and pictures poured into his mind in one breath, and a huge amount of information filth impacted his brain uncontrollably.

In this peculiar tunnel that seems to be able to touch the left, right, up and down at will, and it seems that there is only the front and the back, all perceptions become erratic.

Countless scenes of talking passed by Barry's eyes, and every scene is a real thing that happened. Barry saw the scene of him hiding in the arms of his parents when he was a child, and saw the scene of his mother being killed and his father entering prison. On the day of the explosion of the cutting-edge particle experimenter, he was struck by a huge lightning from the sky, and he was forced to fall asleep for nine months and gained superb power.

In this tunnel where time and space are both mixed and uncertain, in this region that has penetrated the universe for hundreds of millions of years and engraved the birth, old, sick and death of hundreds of millions of lives, it is extremely difficult to find what you want.

If he is not careful, Barry will fall out, not knowing which era he has entered.

"Half a year ago, the earth, New York..." Barry closed his eyes and muttered silently in his heart. The countless warm images that made him obsessed with and reminisced had to cut through cruelly, looking for the time he wanted.

"found it!"

The Flash suddenly opened his eyes, his striding legs stopped abruptly, turned quickly, and hit the side wall with one head, the huge passage opened, the red arc passed, and the Flash's figure disappeared into the space-time tunnel.

Huh!

At the moment when the tunnel was about to close, an undead suddenly rushed out, the lower body was mutilated, the upper body was withered, and the undead had incomplete facial features.

...

Six months ago, the earth.

A huge wave erupted in a no-man's land on the earth, and the electric arc of lightning and thunder oscillated, tearing the soft soil and setting off huge smoke and dust.

Where the red arc passed, the Flash wearing a red suit stopped, but the super kinetic energy and inertia still allowed him to ski out for thousands of meters like skiing in this no-man’s land.

This is already the result of his desperately slowing down.

"It should be this era..."

The Flash watched vigilantly, then slowly "jogged" and came to the nearest farm at a speed of one hundred times the speed of sound, using the super-fast shock ability given to him by superb power, without damaging the doors and windows Easily penetrated the wall.

"March... the time is right. The unknown monster being expelled? The impact of the guardian's resignation? The mutant immigrants?"

The Flash flipped through the latest newspaper, then put it down, his eyes bright and excited.

he made it! He really did it! Shuttle timeline!

As long as he finds Downey~lightnovelpub.net~, he can ask him to stop Steppenwolves. Those superheroes and civilians who have died will not die, nor will Australia be destroyed!

All tragedies will be covered by new reality!

"If... I return to that night..."

The Flash suppressed his excitement, desire, and a trace of panic. It was not the time to consider how to save his mother who was killed by the mysterious speedman when he was a child, but to find Downey.

The red figure flashed, and he rushed to the direction of New York city center, where there was the possibility of changing the tragic future.

Just when his front foot disappeared, an undead chased him with deep disgust and killing intent, and then stared at Barry's back and chased him.
