Road surveillance is like an eye that tracks everyone's whereabouts everywhere, and with the right approach, you can track all the whereabouts of a specific target from a specific camera.

Roy found a brown van in a street camera about twenty meters away from the kidnapped boy's house, and another brown van and a brown sports car in two cameras in the other direction.

He then spent a lot of time watching videos of various intersections, finding the target vehicle from different footage. He then used a map to map out the routes of each of the three cars and find out where they ended up.

As luck would have it, one of the vans and the sports car went to public places that could be excluded, with only the last van eventually escaping the surveillance range. However, if you analyze the direction in which it goes, it is easy to find that there is only one place in that area where a person may be hidden. It was once a prison, then converted into a steel mill, and is now abandoned.

What better place to lock people up than in an abandoned former prison?

The whole case was actually quite simple, at least for Roy, who was able to pinpoint the location of the hostage in less than a day, which was really not that difficult.

He called Kassandra, pointed to the steel mill circled in red on the map, and said, "This is it." ”

Kassandra stared at the circle drawn by the red pen with a determined expression. Without too many words, she only said one word lightly: "Go." ”

Outside the steel mill was arranged to be quite tightly guarded, three steps and one post, five steps and one sentry, just to watch a young man who had been beaten to death.

"What did that soft boy do inside?" One of the criminals guarding the door asked, "Does he deserve such a big deal of anger from the eldest brother to arrest him?" ”

"You don't know? This idiot tried to play some 'hero saves beauty' and ruined the good things of the big brother. The other replied.

"Seriously? Will there be such a stupid guy in these years? Then he can really use the rest of his life to reflect. ”

"Boom!"

The dull sound of a hammer striking a city gate frightened everyone who was guarding it.

"What's going on?"

Loud noises rang out one after another, and the heavy metal door at the side door caved in with a roaring sound.

The heavy door panel collapsed, and a black shadow flashed in. Before they could see what it was, the gangsters opened fire in horror. Bullets rained down on the shadow.

But the shadow was like a ghost, blocking the bullets with the help of various equipment in the factory, and approaching the gangsters who opened fire one by one. Every time he came to a person's side, the whole person seemed to turn into a sharp black sword, and in a flash, he knocked a person unconscious.

Roy didn't make a move. Just watch from the back. Kassandra's movements were impeccably fast, she rushed in like a moving machine, and then sprinted unstoppably through the hail of bullets, and the battle was almost over in less than a minute.

There was only one man left. Kassandra dodged the muzzle and jumped behind him, slamming the fellow's throat with her tiny arm. The gangsters who fell into suffocation turned out to be only the last consciousness that remained. He took out the cell key and threw it towards a river outside the window.

Kassandra was so frightened that she hurriedly left the criminal and reached out to try to catch the falling key outside the window, but finally her fingertips were still a little short of reaching.

In frustration, she turned around and kicked the criminal, who had re-raised her gun to sneak up, and climbed to the fence of the small window in front of the cell door to peer in. She could see the boy sitting dying against the wall on the floor, eyes closed and seemingly unconscious.

Fortunately, this place seems to have been abandoned for too long, and the door locks have rust, which saves the effort of picking the lock.

Roy kicked the iron door, and the rusty lock collapsed. Kassandra couldn't wait to pick up the unconscious Qin Yi.

The boy woke up slowly, saw Kassandra in front of him, and said with difficulty, "I see you again...... Isn't that a dream? ”

Kassandra held his hand. Shake your head.

"I felt like my ribs were loose...... "I'm going to die?" he said. ”

Kassandra shook her head again, "No. ”

Sirens and ambulances sounded outside the window.

"It's time to go." Roy reminded in a low voice.

Kassandra kissed the teenager on the forehead: "Goodbye, hero. ”

Gotham.

As usual, a "normal" night - a gang of criminals are beaten half to death by bats falling from the sky, then forced to confess something they don't know, and finally packed up and sent to the Gotham police.

Batman has tried to get clues about the Bishop from various sources, but no one knows where he is. There were a few times when he found clues that might lead him to something, but they all ended up finding an empty abandoned warehouse.

And today, as he continued his nighttime operations, Barbara actually said through his communication line that he had discovered something. U Reading Books (wwwuukashu.com

When the communication is connected, Batman is holding the collar of a frightened guy in his hand. He frowned and asked, "Oracle?" What's wrong? I'm a bit busy right now. ”

"I know. But I think I made some groundbreaking discoveries. ”

Barbara is sitting in front of the Batcave's supercomputer, playing a video at slow speed. The video resolution is not high, and the scene inside seems to be a subway station.

"I used facial recognition software to find a Russian killer." Barbara explained, "Roy used to tell me. He felt that when the Bishop first developed, he may have used the power of the Russians, and it was likely that the Russian gangs that had recently been brought to Gotham were the Bishop's earliest allies, so this killer caught my attention. Then, I found something interesting in the surveillance footage of a subway station. ”

Batman tossed the scared criminal aside and turned to walk towards the Batmobile. Q: "What did you find?" ”

"The Russian got on the train from a certain metro station." "But I checked the footage of all the platforms from that station onwards and saw that he didn't get off at any of them." It was as if he was on the subway and then the whole thing was gone. ”

"There's also a platform in between." Batman frowned and said, "I remember." Originally, there was supposed to be another station in the middle, and even the platform was repaired, but then the construction was stopped due to legal disputes, so there was no above-ground exit in the end. ”

"Wow, if it's really a hiding place, then I'd say I'll really find a place to hide." Barbara sighed.

"Stay online, oracle." Batman said, "I'll go there right away." "To be continued.
