In the winged knight's stronghold, the crisp sound of "ping pong" is endless. r?a?? nw?en?ｗ?ｗ?ｗ?．??

Barbara, who has been in a wheelchair for three years, is now finally back on her feet. Not only that, but she was even able to regain her old skills and fight Roy in one place.

The two men each held two steel rods in their hands, and each collision was like the sound of percussion loud and loud.

"Ahh Barbara was careless, and Roy was knocked on the back knee joint, and her body fell to her knees.

"You're slow." Roy said, "You're still recovering. ”

After a pause, he asked again, "Are you feeling okay?" ”

"If you're asking a girl who's been in a wheelchair for three years and now standing up again, yes, I'm fine." Barbara smiled, then asked worriedly, "What about you?" ”

How far from Sully? It's been a while since Sarasota was captured, and Nightwing has of course told Bruce and Barbara about Roy's loss of control. Bruce asks him to go to the Batcave for a series of check-ups, but nothing happens. Bruce continues to work on a solution to remove the venom residue from his body, but so far little progress has been made.

"I said it, I can control it." Roy replied. After defeating Sully for a while, the abnormality in his body did stop, and the situation is basically stable for now.

The mobile phone placed on the table emits a text message reminder tone. Roy stepped forward and picked it up, looked at it, and said, "Looks like we're busy again, Xiaoba." Your leg looks like he's recovering well, right? ”

"What else does this need to say?"

"That's great." Roy said, "Because I want to take you with me this time." ”

The case was born in a deserted and empty house in a slum area, the place is somewhat remote, there is not even a single piece of cement around the house, and the ground is covered with mud and some weeds.

Roy and Barbara get out of the taxi and push open the main entrance and enter.

It had just rained last night, and now the sky is still gray. The air is humid, and every step kicks up earth-colored dirt. Roy made his way down the path cleared out of the weeds, his eyes glued straight to the ground all the way, frowning from time to time.

"It's messy, isn't it?" Barbara quickly understood what he meant.

The ground was trampled in a mess, and it was easy to understand that most of them were the footprints of police officers who came to the scene to investigate, and it was quite serious damage to the scene.

Walking into the empty room, the corpse immediately attracted the attention of the two. It is indeed difficult to ignore it, and it is very striking to lie flat in the middle of an empty room.

The deceased was male and appeared to be between thirty and forty years old. He wears a light gray jacket and matching pants, black leather shoes, and the soles of his shoes have dried mud. He wears a tie with yellow stripes on a black background. There was no pain on his face, but it was full of fear, and the blood hole above his eyebrows was clearly the cause of death.

Roy crouched down to scrutinize the bullet holes in the corpse's head and the puddle of blood on the back of his head, then turned to ask, "What do you think?" ”

Barbara was stunned: "Ask me?" ”

"Of course, this is the first time you've been to the site with me in person, so I'd like to hear your opinion."

Barbara nodded, thought for a moment, and was about to speak when someone interrupted her.

"Xiaoba?"

The two looked back, only to see Director Gordon walking briskly towards the two: "What are you doing here?" ”

"I," she glanced at Roy, "assistant advisor?" ”

Gordon complained: "I don't want you to be a police officer, and I certainly don't want you to be a detective consultant." ”

"But didn't you say not long ago that you respected my choice to work with him?" Barbara asked rhetorically.

"That's when you," Gordon said at this point, pausing involuntarily, "when you couldn't find a job like a normal person." But now it's different, you have a brilliant brain, you're very good in every way, you can find anything else to do. ”

"You said last time that you would respect my choice, because that's where I can get out of the shadows and find hope again." Barbara said seriously, "I love you, Daddy, but I can't continue to follow the route you've laid out for me." That's the way I chose, I'm an adult and I should be able to make my own decisions. ”

Gordon stared at her for a long time and sighed, "You're right. When you're older, you should be able to make your own choices, okay, let's get down to business. ”

He turned to Roy, "Tell me, what do you think this time?" ”

"Actually, Director Gordon," Roy smiled slightly, "I'm about to hear your daughter's opinion. ”

Barbara walked to a wall behind the deceased and looked roughly, "If the deceased's body hadn't been moved since he was shot, I think the bullet should have been found here." ”

Roy tacitly handed her tweezers, and she pinched the bullet out of the badly peeled wall.

"And obviously, the deceased should have known the murderer." Barbara put the bullet in the evidence bag and said, "There should be no reason for the deceased to come alone in such a remote place, so he may be talking to the murderer here." Perhaps we can start with the social circle of the deceased during his lifetime. ”

Gordon nodded slightly: "Then we have to solve another problem first, we are still trying to confirm the identity of this deceased." He has no papers on him, nothing in his wallet but cash, and it may take us a while to confirm his identity. ”

"I probably know a little bit about identity." Barbara said, crouching back beside the deceased.

She took out a black pen from the jacket pocket on the outside of the deceased's chest and said, "This, can help us narrow it down." This is a certificate of honor from the University of Edpooron to the senior professors of the college. The deceased was a professor at the University of Edpooron, and probably quite successful. ”

"How do you know this?" Roy asked.

Gordon took a breath and replied for his daughter, "Because, she graduated from that university." ”

Roy made a look of surprise and continued, "Careful observation, but there is a clue that may be useful. ”

He pointed to the ground outside the door: "Footprints." ”

Barbara spread her hands: "But you said it, it has been trampled by the police officers investigating the scene and is unrecognizable." ”

"Yes." "But we now know the size of the shoes on our victims' feet, and the patterns on the soles of the feet, and I can tell which footprints were stepped on yesterday and which are today." ”

"Oh." Barbara said, as if lamenting how she hadn't thought of it.

Roy came into the courtyard, crouched down, and carefully studied the footprints on the ground. He observed for a long time, going back and forth in circles like a hound tracking scents.

"Looks like this group." Roy half-crouched and said, "This column of footprints should match the shoes on our victims' feet." And the column next to him has kept this distance from him. The two enter the house together, and then get into an argument inside that leads to murder, or possibly the killer had planned to kill the professor before he arrived. ”

"Judging from the footprints, our murderer is estimated to be about 1.7 meters tall and will not weigh more than 190 pounds. He left cigarette ash in the antechamber, which of course could not have been left by the deceased, as it was evident from his mouth that the deceased was a non-smoker. So our murderer smoked a double T brand cigarette. ”

After he finished speaking, he stood up and said, "So, let's first confirm which professor of Aspton University the deceased is, and then find out from this professor's social circle a person who smokes a double T cigarette and is 1.7 meters tall, and this person is our murderer." ”

Gordon looked at his daughter, then at Roy, and said, "If I had a dozen agents like you at my police station."

"Or you can fantasize about a dozen Batmans at your police station." Barbara complained.
