Although he loved the dagger as a gift very much, for Bruce, this meant that Moon was leaving.
"Teacher, are you leaving now?"
"Well, almost, I'm leaving soon." Mu En nodded and looked at the two of them, "Although I'm leaving, your training must not stop. Don't forget that I will check on you when I come back."
He has been dragging here long enough. He originally planned to find the Dionysus factor in Gotham to extract the essence of Aye, but failed.
If he hadn't extracted the essence of Aye from Diana and the flaming sword in the museum, then his time would have been completely wasted.
Huh~
Suddenly, a ray of silver light flew out of Mu En's hand and shot into the flower bed in the courtyard.
A cry of pain was heard, and several killers wearing masks appeared around them. On their foreheads, all of these killers had emblems like a drop of blood.
"You two hide for now, and I'll deal with them. Think of it as the last lesson I teach you before I leave."
As soon as he finished speaking, several more kunai shot out from his hand, and two Rex pistols appeared in his hand, firing at the killers.
Bang bang bang...
The sound of gunfire echoed in Wayne Manor. The Rex twin guns, which were also fused with amplitude crystals [Wasp Sting], had a powerful lethality that was not inferior to anti-material weapons.
Although these killers were heavily armed, when faced with Rex's attack, their protective measures were basically the same as none, and they were unable to defend themselves against the bullets fired by Rex.
With the first few killers as examples, the other killers hid one after another. They all understood how destructive that seemingly unremarkable pistol was.
Seeing that all these killers were hiding, he walked towards them, intending to kill these guys completely.
Tap tap tap
Hearing the footsteps getting closer and closer, a killer stretched out the barrel of his gun and fired back and forth in Mu En's direction.
But the result was that he was disappointed. That attack did not hit Mu En at all, but allowed Mu En to determine their position.
Stepping lightly, he ducked in front of the nearest killer. As gunshots rang out, the killer's head was blown to pieces by Rex like a watermelon that fell to the ground.
"one……"
Muttering softly, Mu En continued to kill the next killer.
Before the killer could react, there was another gunshot, and another killer was completely dead.
"two……"
His counting sound, like the god of death harvesting souls, made the remaining killers unbearable, and they all leaned out and shot wildly at Mu En.
But their situation was destined to be tragic. The moment they leaned out, the Rex in Moon's hand began to shoot one by one.
Da da da……
Bang! Bang! Bang!
Every time Rex rang, there would be a bloody hole in a killer's body, someone's head would be shattered, and someone would have a fist-sized hole in their heart.
Bang~
With the last gunshot, the last killer fell.
However, this killer only had one of his legs broken, and Mu En still needed to find something from his memory.
Bruce and Serena, who were hiding aside, couldn't help but shrink their necks after seeing such a situation. The teacher was always very cold when facing the enemy.
"You go find Ah Fu, I'll go out."
After saying that, Mu En carried the killer and walked towards the outside of the manor.
As soon as he walked out of Wayne Manor, Moon turned into energy and disappeared, while the killer was like a puppet with its strings cut off, leaning against the wall motionless.
Not long after, the killer's chest was suddenly torn apart, and a swarm of razor butterflies flew out of the killer's chest.
"Get rid of everyone with the blood drop emblem!"
As the sound rang out, the killer's body turned into ashes in an instant, and in the ashes flew out of the razor butterfly group.
The razor butterflies dispersed in the air and flew to various parts of Gotham.
And people in Gotham also saw this strange sight. A group of beautiful butterflies shuttled around Gotham, flying past some people from time to time.
After a while, alarm bells were ringing all over Gotham. Although the Gotham police were not very good, the superficial stability still needed to be maintained.
They received an alarm and saw a group of butterflies flying past those people, who then fell to the ground covered in scars.
Gordon and his partner Harvey were also detectives who received the call. When they arrived, the deceased was no longer breathing and was lying straight in a pool of blood.
"What's going on?"
Harvey now has a headache. Gotham has become more and more troublesome recently. In the past, it was just robbery, shooting and so on.
What now?
Someone was killed in prison, someone's pancreas was taken away, and there were several fresh skeletons of unknown identities.
The current situation is more troublesome than what he has experienced in the past ten years or so. Even if he wants to find a scapegoat, he will not be able to get rid of it.
Gordon knelt down to check the deceased's injuries. The deceased's neck was only connected by bones, and the rest was torn apart by sharp blades.
"Such an injury is not something a butterfly can do. It looks like it was done by a strong man."
Gordon came to the conclusion and called Harvey to take the body back to the police station. They needed a more in-depth examination.
But after they brought the body back to the police station, they discovered that the morgue in the police autopsy room was already full of corpses.
"What is red and important to people?"
A thin young man appeared next to them, holding a pen and asking the two of them.
"Uh...Edward, we don't have time to guess riddles." Gordon looked at the other person with a helpless look on his face.
"Okay!" Edward shrugged and handed over a document. "The answer is blood. They all have this blood drop emblem on their bodies. They should be an emerging killer organization."
Gordon's eyes lit up, he grabbed Edward's shoulders and asked:
"You mean, they were all killed by this blood drop organization?"
"No, in fact it's the opposite of what you guessed, they are the killers!"
This is the conclusion that Edward came to after investigating the identities of these people and the items on their possessions.
The rumored butterflies are hunting the killer who appears in Gotham.
…
After the last killer with the blood drop emblem was killed, Moon returned to Wayne Manor.
But instead of going to meet Bruce and the others, he sent a Razor Butterfly.
"You stay here to protect them."
This razor butterfly was born from the ashes of the killer, and was not Titania's own razor butterfly, so he planned to keep this razor butterfly to help Bruce guard against possible killer attacks in the future.
After watching the razor butterfly draw a blue light in the air and fly into Wayne Manor, energy flashed through Mu En's body, and Limbo came online.
A crack opened into the void behind him, and he stepped out of it and completely disappeared from this world.
After Bruce and Serena saw the flying razor butterfly, they ran out of the house in a hurry, but Mu En was nowhere to be seen.
