Barry Allen slowly stood on an elongated version of a huge treadmill, his body kneeling, ready to sprint with all his might.

"I warn you that this is a risky move with a lot of unknown consequences. Your task is to find Donnie half a year ago, don't do superfluous things, remember! I think you know how terrible the butterfly effect is, don't do anything superfluous! ”

Dr. Harrison pushed his glasses with a serious expression.

The cosmic treadmill is a restored machine built by Harrison according to the original historical trajectory of Barry Allen, which was originally used to assist him in traveling 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, you made it clear when we built this treadmill together."

Barry nodded heavily, tightened the red hood he had always worn on his head, took a step, turned his head to look at the heroes around him who were looking forward to him, and then slowly posed, a strong red arc in his eyes.

Buzz Buzz......

Barry took small steps and ran, getting faster and faster, gradually surpassing the speed of normal people, and still increasing his speed frantically.

"A hundred times the speed of sound."

"Two hundredfold ......"

"500 times ......"

"A thousand times! He's so fast, I can't even see him! ”

Sisko operated in front of the instrument, watching as Barry's speed remained constant at a thousand times the speed of sound.

At this time, on the cosmic treadmill, Barry ran wildly, and the whole person erupted with terrifying red arcs, these arcs flashed at an alarming frequency, and more and more, gradually enveloping Barry's body.

The power of the speed force was used by Barry and transformed into a massive red arc, which was like a projection of a god in a huge thunderbolt.

The terrifying and furious force caused the crowd around them to retreat, and the entire ground began to tremble, and a huge crack cracked from the ground below the treadmill and spread in all directions.

The rapid increase in speed makes Barry's running action turn into an afterimage, and the afterimage superimposes on the afterimage, making Barry who is running blurred.

"It's now! Barry, open the passage! Identify your goal, feel the guidance of the speed force on you, and be sure to accurately locate it half a year ago! It's a choice you stick to, so stick to it! ”

Harrison yells!

Rumble!

Barry's figure faded into obscurity, and in front of the treadmill, a huge whirlpool tunnel opened, blooming with an ominous blue color, and the deep, dark color flashed in the very center of the gap, slowly converging into a ball.

Until a loud bang came, accompanied by a huge red arc explosion, a large number of items were flying, Barry's figure disappeared completely, and the vortex also lost the support of the speed force and quickly closed.

There was an unpleasant smell around the cosmic treadmill, a burning smell caused by a lot of friction in the air.

"He succeeded?" Tony looked at the vanished red-clad runner in amazement.

Harrison took off his glasses, wiped them, and said calmly, "He'll make it." ”

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

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

"The Flash...... Traveling through the timeline? Clever and stupid guys. ”

The moment Barry Allen entered the time tunnel, countless noises and images poured into his mind in one go, and a huge amount of information filth hit his brain uncontrollably.

In this strange tunnel, which seems to be easy to touch on the left and right, up and down, and seems to have only the front and back, all perceptions become erratic.

Countless talking images passed by Barry's eyes, each of which was a real thing, Barry saw the scene of him hiding in his parents' arms as a child, the scene where his mother was killed and his father went to prison, and the scene where he was struck by a huge lightning bolt falling from the sky on the day the cutting-edge particle experiment exploded, and was forced to sleep for nine months to get the speed force.

In this tunnel where time and space are mixed and uncertain, in this area that has carried hundreds of millions of lives, old age, sickness and death engraved through the universe for hundreds of millions of years, it is extremely difficult to find what you want.

If you're not careful, Barry will fall out of the way, and you don't know which era you've run into.

"Half a year ago, Earth, New York......" Barry closed his eyes, silently reading in his heart, countless warm images that fascinated and reminisced him, and had to be ruthlessly cut off, looking for the point in time he wanted.

"Found it!"

The Flash suddenly opened his eyes, his striding legs suddenly stopped, quickly turned, and crashed headlong into the side wall, the huge passage opened, the red arc crossed, and the figure of the Flash disappeared into the time and space tunnel.

Ga!

At the moment when the tunnel was about to close, an undead suddenly burst out, the lower half of the body was mutilated, the upper body was dry, and the undead with incomplete facial features reached out and tore the gap that was about to close, and then screamed and drilled in.

……

Half a year ago, Earth.

A huge wave erupted in a no-man's land on Earth, and the arc of lightning and thunder vibrated and tore through the soft dirt and kicked up huge clouds of smoke and dust.

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

This is already the result of his desperate slowdown.

"It should be the ...... of this era"

The Flash looked around vigilantly, then slowly "jogged" to the nearest farm at a speed of a hundred times the speed of sound, and used the super-fast concussion ability granted to him by the speed force to easily penetrate the walls without breaking the doors and windows.

"March...... The time was right. An expelled unknown monster? The impact of the Guardian's resignation? Mutant big immigrants? ”

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

He did it! He really did it! Travel through the timeline!

As long as he finds Donnie, he can ask him to stop Steppenwolf, and the dead superheroes and civilians will not die, and Australia will not be destroyed!

All tragedies will be overlaid by a new reality!

"What if...... I go back to that night......"

Suppressing his excitement, longing, and a hint of trepidation, the Flash is not the time to think about how to save his mother, who was killed by the mysterious Speedster when he was a child, but to find Donnie.

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

Just as his front feet disappeared, an undead spirit chased after him with deep disgust and murderous intent, and then stared closely at Barry's back, chasing after him.
