The Ultimate Executive of American Comics

City, police station. .

Joe and Barry got in the car and began their continuing investigative journey. After Tang Tian revealed some secrets, Qiao made up his mind to investigate the past cases.

On the asphalt road on the outskirts of the city, a car stopped in front of a house, and two people walked out, it was Barry and Joe West.

"Barry, would you feel scared returning to your old home?" Joe turned to look at Barry and asked him.

"In the past, it may have made me a little desperate, but now you are enough to help me." Barry said gratefully to Joe.

Joe patted Barry on the shoulder and said encouragingly: "Barry, I swear that I will restore your father's innocence. I will go to Star City tomorrow to conduct an on-site investigation."

Barry nodded to Joe, they looked at each other and smiled, and Joe knocked on the door. This house was Barry's former residence.

"Dong dong dong!" Joe didn't knock a few times, and a young woman in pajamas came out. After opening the door, she gave Barry and Qiao a wink without asking anything.

"Um..." Barry's expression was filled with chills, as if he had eaten a fly, but he managed to maintain a stiff expression.

Because the clues to investigate their mother's murder are inside, they can't back down. Joe saw Barry's expression, walked out and said to the young woman in front of him: "Hello, madam, there was a case in this room before. We need to investigate. Can we go in and investigate?"

"It doesn't matter, I live here alone." The young woman said to Qiao "meaningfully", and even Qiao couldn't help but put down his hand that was about to take the police officer's certificate.

When Qiao heard this, he couldn't help but break out in cold sweat, but his good qualities made him nod his head and said, "Thank you for your cooperation, ma'am."

After Barry and Joe walked in, Barry looked around the house and sighed. The feeling of things changing and people changing made him a little sentimental.

Joe took the file from that time and explained to Barry in detail the location, direction, and some details of his mother's murder.

"Oh, it's been too long, it's been fourteen years." Barry said helplessly. He knew that the change of time had caused many key pieces of evidence to disappear.

"Yes, Barry, but have you noticed that only the front mirror has not changed." Joe looked at the photo carefully and said affirmatively.

Barry walked towards the mirror. This object, which had hardly changed in the photo, showed a thoughtful expression.

"Wait a minute, Joe, what is the material on the back of an old-fashioned mirror?" Suddenly, Barry had a flash of inspiration and asked Ma as if he thought of something.

"Silver nitrate." Joe said with certainty. As an experienced police detective, he knew a lot, so he reacted immediately.

"Silver nitrate is mostly used in photography and on the back of old-fashioned mirrors. If this was the case, then the flash caused by the electromagnetic sparks generated by the speedster was continuously exposed to the silver nitrate, then our key is to create an image in the mirror. "

Barry showed a smile. He was obviously very excited to find these key evidences, which meant that he was one step closer to a breakthrough.

"Sisko's equipment can restore the original scene, which is of great help to us." Barry was surprised and thought of the team behind him. It might be better to let Sisko help.

"Okay, Barry, you go find those images, and I'll go to Star City to check them out." Joe nodded to Barry, and they left the house with the mirror.

At the same time, Star City Base 34, control room.

Betty walked up to Tang Tian in military uniform and held the item, and said to him seriously: "Sir, we found that Barry Allen and Joe West went to a house once and took a mirror with them when they left."

"Well, go down! Betty, I understand." Tang Tian nodded thoughtfully and ordered to Betty.

"Yes, sir." Betty said respectfully, and then left the control room.

"They are about to reveal the truth. What role should I play?" Tang Tian showed a meaningful smile and looked in the direction of the city.

At this time, Hartley also walked in. Looking at Tang Tian's thoughtful expression, he smiled and said, "You seem to be paying close attention to the cutting-edge laboratories. Have they also discovered Wells' secret?"

Hartley's eyes flashed with anger, and he was still a little bit resentful that Wells kicked him out of the cutting-edge laboratory.

"Hartley, you are right, this is the current situation." Tang Tian smiled and explained.

"So what role will we play?" Hartley asked with interest.

"Just wait and see what happens." Tang Tian said affirmatively.

Tang Tian didn't feel the need to intervene in the relationship between Barry and Reverse Flash. He himself doesn't like to get into trouble by meddling in other people's business. Unless there are conflicts of interest, he doesn't really care about anything else.

"By the way, I have something to show you. I am very knowledgeable about sonic weapons. As long as I find the resonant frequency of an object, I can almost destroy matter." Hartley said confidently.

"Of course, buddy, I believe you." Tang Tian patted Hartley on the shoulder and said with a smile.

"Your sonic weapon has great potential, I'm more optimistic about it." Tang Tian patted Hartley on the shoulder and said with a smile.

What Tang Tian knew was that Hartley's sonic frequency had great resonance potential. If thoroughly developed, it would be easy to destroy any physical structure.

For example, in the early 19th century, a group of Napoleonic soldiers, under the command of their commander, crossed a bridge in Angers, France, with majestic and uniform steps. When they were about to reach the bridge, the bridge suddenly shook violently and eventually broke and collapsed, causing many officers, soldiers and citizens to fall into the water and die. After investigation, it was found that the culprit of this tragedy was the consistent resonance frequency.

Because when a large group of soldiers walked in unison, a frequency was generated that was exactly the same as the natural frequency of the bridge, which intensified the vibration of the bridge. When its amplitude reached the maximum and exceeded the bridge's pressure resistance, the bridge broke.

The same principle applies to Hartley's sonic weapon. When the frequency of the sound waves is equal to or close to the same, and the resistance of the material is not enough to consume the energy of their mutual excitation, then the vibration of the entire material will be unstable, and the amplitude of the vibration will become larger and larger. It grows bigger and bigger until the object is completely destroyed.

Tang Tian is also optimistic about Hartley's research direction. In the second season, Hartley used the principle of sonic resonance to repel the time undead who were chasing Barry Allen. It can be said that he is very powerful.
