Quick Transmigration: Homewrecker System!

[Sigh, we've been in this world for almost a month already. I've been loitering around Neo Yokto for so long. Why can't you give me a heads up and tell me where the ML's hiding spot? Wait, I think, you should tell me who is the master of this world again, a month not talking with a handsome man gives me a slight amnesia.] 

Yunyu was jumping from one building to another with his magnetic boots, he did this for almost one month just to deal with many small crimes. He should be tackling big crimes too, but the world was surprisingly peaceful the moment he transmigrated.

[Pupa: You are Yukio Amano, thirty one years old vigilante, and an ex-cop that was fired five years ago for trying to uncover the dirty secret of the cops. You've been stripped from all your ranks and now work as a vigilante with donation money you got from people whom you helped.]

[Then, the master of this world?]

[Pupa: The master of this world is Sakuma Hoshino, a twenty three years old shut in or hikikomori. He has become a shut in for almost eight years already. A traumatizing chain of events when he was fifteen years old caused him to withdraw from the social circle.]

[… he is just a shut in, what kind of ridiculous thing he can do to destroy the world?]

[Pupa: He is a very talented, perhaps a genius inventor, mechanic, and scientist. To fulfil his desire of companionship, he started creating android robots with amazing self-developing artificial intelligence. He started creating android robots for companionship, but he kept adding more in his creation, that he created an army of death machines.]

[Pupa: By the time of his death, the self-developing AI triggered its own self-destructing system and commanded an army of death machines to destroy the world alongside its creator. Because apparently, Sakuma Hoshino wished for companionship, so the AI translated that into bringing the world down with its creator as companionship.]

[Wow, that's fucked up. Who would've expected that a lonely hikikomori could destroy the whole world with the army of waifus.]

[Pupa: He is a good, young man, but he is very hard to approach and his trauma is really bad. You should find him soon, or he will keep progressing with his army of death machine.]

[Well, how can I find him if you can't even detect his presence? He must be far away from Neo Yokto, right?]

[Pupa: Be careful, someone is following you at high speed.] 

The moment Pupa mentioned that, Yunyu looked behind and saw a female with flat expression chasing after him with her extreme speed. Yunyu was spooked that he lost his footing. He slipped at the rooftop of one building and fell embarrassingly. 

[Holy shi—! I thought I just saw a ghost!]

The female stopped chasing and stood silently in front of Yukio. She scanned the body and confirmed her target, "Target confirmed, thirty one years old, Yukio Amano. Unemployed, working as an illegal vigilante in Neo Yokto. My master has been keeping a close watch over you."

Yukio got up and stared at this female android suspiciously. He was not exactly fond of artificial intelligence, especially a high tech android like this female robot. Because he had a bad experience of androids being used by the dirty cops in Neo Yokto as a means of suppression. 

Sensing the wariness, the female android initiated a conversation first, "I am here on behalf of my master's request. He sees that you have a good heart, but lacking in technology. He wants to upgrade your biochip for free."

The flat, robotic voice still left an unsettling feeling in Yukio's heart. Years of being a cop in Neo Yokto taught him one thing, never trust anyone who wanted to touch your body or biochip for free.

He had a high quality biochip that might be tempting for some, and this female android said that her creator had already watched over him for a while. He was not a naïve boy who knew nothing about biochip control either.

"I don't know you, and I don't want to have anything with you or your master. I refuse," Yukio said firmly. He turned his back, about to jump to another building again. But soon, he found a high concentrated laser beam just shot between his legs.

Yukio turned his head, and saw the female android had unloaded her weaponry. Her right arm disassembled on its own and turned into a cannon, while her left arm turned into a sword, "My master said that this is for the good of the people. If you refuse, then small violence will be enough to carry you to his hideout."

"Commencing attack, preparing assault."

Yukio gritted his teeth, he tapped his biochip and then activated a command, "Operation Attack number 3: Magnetic Bullets."

Bang! Bang! Bang!

Yukio's metallic arm activated by opening a hole in his finger, he pointed his index finger at the female android and shot a few bullets. The female android swiftly dodged and attacked Yukio with her sword arm. 

Yukio took a few steps back to dodge it and the bullets that missed before started moving again from the ground and chased the female android. The female android noticed this and did a somersault to avoid the bullets. 

Yukio shot a few more rounds of bullets, seeing no way to escape the barrage of targeting bullets, the female android skilfully used her sword arm and chopped the bullets in half. 

The female android locked on Yukio again and did a quick shot with her cannon arm towards Yukio. Yukio tried to dodge, but the attack was fast, so he got hit in his left leg. 

"Ack!" Yukio staggered because of the pain. But he endured the pain and tapped his bionic chip again, "Operation Defend Number 11: Electromagnetic shield!"

Yukio's body was covered by an electromagnetic shield as he tried to activate another attack. But the female android quickly delivered a barrage of strong laser beams at him. Yukio couldn't activate his bionic chip with too many attacks coming at him even after he got protected by his electromagnetic shield, in the end, the electromagnetic shield broke and Yukio was thrown to the wall.

"Argh!" Yukio writhed in pain as his body hit the wall. 

He tried to touch his chip again to run away, but the female android gripped his hand, almost crushing it, "My master is eager to see you. I will show the way."
