The ghost was draped in his dark green robes, and lay there straight, not moving at all.?'?

But still have to beware of the possibility that this is another little trick of his. Roy stepped in lightly, slowly approaching the ghost's side and turning him over.

Barbara saw behind him what it looked like under the green cloak, and couldn't help but let out a low cry and cover her mouth.

Under the ghost's cloak, the entire head was cut off from the neck to the neck, leaving a shocking severance. There was still residual heat in his corpse, and even at this moment, fresh blood was gushing out of the broken part of his neck, and anyone in their right mind could not help but stand on end in this situation.

"What's going on? Gang fights? Barbara asked, "But where did the attackers come from?" We've checked, and there should be no other entrance to this chamber, and even if you want to enter the underground tunnels, you have to go through a passage guarded by the ghosts. We relied on your internal response to attack through the main entrance, but how did this intruder who preempted us do it? ”

Roy crouched down beside the ghost, turned the headless corpse over and over several times, and said, "Knife wounds." The cut of a sharp knife - most likely even the blade of a professional assassin killer, is easily evident from the cut in his neck??.?? And the knife was very fast, and the impact was strong, otherwise he wouldn't have thrown his head so far. ”

Roy said, pointing to a long trail of blood that stretched out from under the corpse, "His head was slashed straight to that side by this knife, about ten paces away. ”

"So this killer has a lot of strength, huh?"

"Not really."

Roy said, turning on the flashlight on his armour's wrist. Illuminates the side of the wall of the room that the light does not reach. I saw that there was a bloody footprint in the place where he was illuminated by the flashlight.

"Oh my God!" Barbara exclaimed.

She certainly wouldn't be surprised that some bloodthirsty killer had left his mark here. What surprised her and even stood on end was that the size of this footprint looked no more than the size of a schoolboy!

"That's the case. There are a lot of questions that make sense. Roy wasn't particularly surprised, and said calmly, "Something like how this killer got in." We carefully checked and confirmed that there was no entrance to this place, but we overlooked one point. In the room just outside of us, the water pipe taped to the wall has an outlet that is directly connected to the heating pipe underground. ?.? If it is the size of a ten-year-old child, bent over and prostrate, it should barely be able to move freely in the pipe. ”

"But you mean a child? No. No way. How could a child do such cruel things"

Before Barbra could finish speaking, Kassandra tugged at her cloak from behind and pointed at herself.

Barbra suddenly remembered that before Kassandra escaped from her biological father, she was also a top killer. At that time, she was just a little girl.

"And it also explains how the wound formed." Roy continued, "Because this hands-on assassin wasn't tall enough—probably not strong enough—he did it this way—jumping. Move sideways on a wall, then use the momentum of a horizontal jump to break the ghost's neck in two. ”

Barbara thought about it carefully in light of the situation at the scene, and it seemed that this was indeed the most factual explanation.

Kassandra walked over to a wall. After lying on it and listening, he clenched his fist and gently tapped on the wall, and then turned his head to face the two. He pointed to the wall behind him.

Both of them will be happy - there is a dark room behind this.

The activation mechanism wasn't too hard to find, and Roy quickly found the switch in the crack in the wall. Secret doors open to both sides. The dark and dirty dark room inside was revealed, and the air was damp and smelly.

A gentleman in a well-dressed formal attire, a richly dressed woman, and two children, a man and a woman, were locked up in this dark room. Each of them was tied with their hands behind their backs. His eyes were covered with strips of black cloth.

Obviously, this is Mr. Mayor and his family who have been snatched away by the ghosts.

Hearing someone open the secret door, several people inside obviously panicked, and their bodies unconsciously shrank inward. Mr. Acting Mayor asked anxiously, "Who?" And now? ”

"Now," Roy said, "you can go home, Mr. Mayor." ”

Ten minutes later, the mayor's family was successfully rescued. Chief Gordon's police team had been waiting outside the Black Gate Prison for a long time, and as soon as the winged knights sent the signal that it had been done, the SWAT officers rushed in.

The acting mayor lived for the rest of his life, and after he came out, he made it clear that the position of mayor - even if it is acting - whoever likes to do it, in short, he will not do it.

It looks like Gotham has to toss around the mayor's question again.

"The entire religious community of ghosts was brutally slaughtered." Gordon lit a cigarette and said to the winged knight standing behind him, "He's himself beheaded." Well, a lot of his men are superstitious fools, but they don't deserve it. ”

"Agreed." Before Roy could speak, Barbara rushed to say, "But don't worry, we'll teach that kid a lesson." We'll let him know that in Gotham you have to have rules in Gotham. ”

Gordon glanced at her.

"Batgirl, I've heard of you, but we don't see each other much." "You know, I have a daughter, who's about your age, and she's smart. You really should know each other, I think you are quite similar in many ways. ”

Barbara was taken aback.

"Oh? Is it? Oh, that's a coincidence, hehe, then next time I have a chance to get to know each other."

The more she talked, the more messy it became, so she simply shut up and wiped her sweat secretly.

"How's that going?"

Hoarse voices came from above the heads of several people. When I looked up, I saw the elusive Batman crouching on the roof of a medium-sized police car at some point.

He asked, "What's the clue?" ”

"Well trained, a very professional killer, but also ruthless. He faced the entire gang with the strength of one person, and it only took a fraction of a moment to eliminate them all. "Also, he left a clear footprint in it, and I can roughly determine that he should be the size of a child about ten years old." ”

Batman frowned slightly.

"What do you know?" Roy asked.

"Nope." Batman said, "Keep investigating, let me know what's going on." ”
