I know this is out of order, but I feel like I need to get this arc done before I can continue with the other stories, especially Arrow and Black Lightning. Hope you guys like it. Also, I know that the method I came up with for creating an artificial speed force is likely going to be different from the canon, but that's why it's called fanfiction, so I don't want to hear it after we find out how it's going to be done in the show. I'm also doing it this way for a specific reason that I hope you guys like.

"So, what's the solution you guys came up with?" Barry asked as he and Iris entered the cortex to see Thawne and Jesse working on the tachyon device.

"We think that we can use this device to supercharge the remaining speed force energy in your system to reach critical mass." Jesse said.

"Why would you do that?" Iris asked, since that sounded dangerous, especially the term critical mass.

"The tachyons are basically physical aspects of the speed force in its purest form that exist without the need of a human host. If those particles combine with the residual speed force energy Barry has inside of him, it should create the reaction necessary to create a new speed force." Thawne explained.

"Kind of like a big bang effect." Barry said.

"Exactly. The energy would keep building up inside of you until it had no choice to be released, creating a new speed force." Thawne said.

"However, I feel like we should warn you about a potential life threatening danger that this experiment poses." Jesse said.

"What kind of danger?" Iris asked.

"Considering that we're basically going to be triggering an explosion similar to the one that created the universe with Barry being ground zero of it, the force of the reaction could end killing you." Jesse said.

"That's a risk I'm willing to take." Barry said.

"Barry, this is too dangerous." Iris said.

"Iris, I appreciate your concern, but this is something I feel like I have to do." Barry said and Thawne nodded.

"Cisco is preparing the pipeline, since you'll need to run in it to reach the velocity necessary." Thawne said.

"Got it. So I run as fast as I can and the matrix handles the rest?" Barry asked.

"Exactly." Thawne said.

"Dr. Wells, we should make sure that the calculations for the tachyon matrix are correct, since while this is risky, any miscalculation we make increases the probability of something going wrong and something even worse happening." Jesse said and Thawne nodded as they moved out of the cortex.

"Okay Barry, this sounds too dangerous." Iris said as she turned to face her boyfriend.

"Iris, we both know that Thawne has likely made his own adjustments with his future science to reduce the risk, since he won't risk something happening to his ticket home." Barry said.

"Still, this is too risky. If something goes wrong, not only will the speed force die, but you will too." Iris said.

"Iris, I have to do this." Barry said.

"Why?" Iris asked.

"It's my fault that the speed force is dying in the first place. If I hadn't forced Oliver to give me his spectre energy back at the vanishing point, we wouldn't be in this mess." Barry said.

"Barry, you made the right call. If you hadn't, we'd all still be dead." Iris reminded him.

"Still, I feel like we should've found another way to get into the speed force. I killed the speed force, I have to make it right." Barry said and Iris sighed.

"I get it, I really do, but at the same time, I have already had to prepare for my life without you once, I don't want to have to go through it again." Iris said.

"I promise, I'll come running home to you. Like I always do." Barry promised and Iris smiled as she kissed him.

"I hope so. And I hope that this works." Iris said.

"Yeah, you and me both." Barry said as Cisco entered the cortex.

"Come on, we're ready to start the experiment. I even have something special for you to wear." Cisco said and Barry grinned.

"You finished it?" Barry asked.

"I finished it a while ago, but I was waiting until we were sure that this experiment would work to give it to you." Cisco said and Barry nodded.

"I'm guessing you've also made suits for you and Cait?" Barry asked, since they'd both revealed their powers to Thawne in a way that looked like it was an accident.

"Yep. But we've both been waiting until the Flash can make his debut, since he's the true protector of this city." Cisco said and Barry nodded at him appreciatively.

"Let's do this." Barry said as they headed towards the pipeline.

"Okay Barry, are you ready?" Thawne called to him from the cortex where he, Iris, Cisco, Caitlin, Jesse and Joe were watching from the monitors.

"As I'll ever be." Barry said as he stood at the entrance to the pipeline, fully dressed in his Flash suit that Cisco had made for him, which was exactly identical to the one he'd been wearing before the universe was rebooted and attached the tachyon booster to his chest over his emblem.

"Okay, now the tachyons will start surging into your system the minute you tap into what's left of the current speed force. Remember, no matter what happens, don't stop running." Thawne said.

"Got it." Barry said as he took a deep breath to prepare himself.

"Now run Barry, run." Thawne said and Barry did exactly did that as he began running as fast as he could as he felt the tachyons surge into his system and he could feel the energy building inside of him until it started to feel overwhelming.

"Guys, I'm starting to feel weird. Like I'm going to blow up." Barry said.

"That just means it's working." Thawne said.

"Are you crazy, shut it down!" Iris shouted at him.

"Iris, we can't. We're too close." Jesse said, though her concern for her brother was quickly rising above her desire as a scientist for this work.

"Jesse, please." Iris said and Jesse nodded.

"Barry, you need to stop now." Jesse said.

"I can't, I'm too close to the finish line." Barry said as he continued running and picking up speed.

"That's it." Iris said and before anyone could stop her, she rushed out of the safety of the cortex towards the pipeline, with Jesse right behind her to try and stop her from leaving the safe zone.

"I'm almost there." Barry said as he felt all the energy building within him about to burst and then finally, it did in a huge explosion, which surrounded Star Labs in blinding white light.

When the light died down, Joe quickly got on the comms.

"Barry, can you hear me?" Joe asked, but there was no response.

"Iris, Jesse?" he then asked, but to everyone's shock there was no response from them either.

"Cisco, search the surveillance cameras for any sign of Barry, Jesse or Iris." Thawne said and Cisco did exactly that, but he was surprised at what he found.

"There's no trace of them anywhere in Star Labs." Cisco said.

"Do you think they were disintegrated?" Joe asked.

"No. They're out there somewhere. The only question is, where?" Thawne asked.

Please don't hate me, but this was too good of a place to not leave a cliffhanger. Next chapter of Flash will be up right after this one since I need to get this arc done before I can continue with the other stories.
