"Woo~!"

With a gunshot from the muzzle of the gun on Spencer's right temple, the brass-colored bullet burrowed unhindered into Spencer's head, and then out of Spencer's left temple, bringing out a small pool of red-to-white solid-liquid mixture.

As the gunfire ended, Spencer's hands hung down weakly, the pistol fell to the wooden floor with a "snap~", and his head with sparse pale hair fell to the side, but because Spencer was sitting in a wheelchair, his body did not fall to the ground.

"Sakiya, let's go."

9S glanced at Spencer, who was dying with an unwilling expression, and said calmly to Sakuya beside him.

"Yes, Master."

Sakiya nodded at first, and then reported to 9S.

"Master, my clone has cleaned up the underground base, do you need to clean it now?"

"No need Saki Ya ......"

9S waved his hand and said.

"Get your doppelgangers back, we've been in this world long enough, it's time to go back."

"Tell the others to pack up what they're going to take, and I'll go back to Billy and leave."

"Understood, master."

Sakiya nodded, controlling her clone and rushing towards her and 9S.

Three hours later—

The 9S driving the mecha spent three hours rushing back to New York from Africa, and when I came home, I found that the house had been cleaned up, and after asking 2B about them, I found out that they knew they were leaving, so they quickly put away all the things in the house, and then went to the location that had changed from the company to the headquarters of the group, and went to say goodbye to Billy.

After taking the car to a hundred-storey building, 9S, who had not yet gone up, was stopped by the beautiful young lady who received it at the front desk.

"Little brother, what are you doing here? You can't just go into this place~"

The young lady in the OL costume leaned forward slightly, reached out and stroked her golden hair, and asked 9S with a smile on her face.

“……”

9S, who was called his little brother again, turned dark and did not speak, but silently took out a mobile phone from behind him and dialed a number.

"Toot ~ Toot ~ Pop ~ "

The phone rang only one or two before it was connected.

"Hey~9S? Are you here or not, they've been waiting for you for a long time. ”

Billy's voice came from the phone, directly startling the blonde lady standing opposite 9S.

'This~ Isn't this the voice of the chairman? ’

At this time, her heartbeat suddenly increased countless times, and if the chairman knew that she stopped someone the chairman knew, her job with a high salary would be wasted.

"Here, I'm downstairs."

"Oh, I'll let the secretary pick you up."

"No need ......"

9S glanced at the blonde lady who had become a [Scared Limited Edition] and continued.

"I'll just go up myself."

"Huh? But ......"

Billy wanted to say something, but 9S directly pressed the hang up button.

"Can I go in?"

9S asked the young lady.

"No, no problem, Mr. Please."

The blonde lady turned sideways a little stiffly, stretched out her hand and pointed to the elevator entrance not far away, and the original little brother also became a little gentleman.

"Don't worry, I won't tell Billy."

When passing by the young lady, 9S said softly, and then without waiting for her to say anything, he walked directly into the elevator alone, as for Sakiya? She was sent by 9S to solve some troubles, and the reason for not solving them was to train Billy and exercise Billy's ability in the mall.

And now that Billy has grown up, then there is no need for those guys to exist, and this is what 9S did for Billy in the end, and Billy will go alone in the future......

"Hey~9S, we've been waiting for you for a long time."

Billy, who sat behind the desk, said with a happy face, but there was a sadness between his eyebrows that could not be concealed.

"2B, did you tell Billy?"

9S raised his eyebrows, looked at 2B sitting on the sofa next to them and asked, in an instant, the atmosphere of the scene directly froze, and an indescribable air pressure hovered over them.

"Well, I told Billy who we were."

2B replied with a slight nod.

"Hey~9S, it's okay to tell Billy, we've known each other for more than three years."

A2, who was standing on the side, waved his hand and said with a dissatisfied face.

“…… Well~ Actually, if you don't say it, I'll tell Billy about us. ”

9S was silent for a few seconds, and just when others thought 9S was angry, he spread his hands indifferently and said.

The frozen atmosphere was suddenly broken, and everyone breathed a sigh of relief.

"But I'm curious about A2, when did you see Billy as a friend?"

As everyone breathed a sigh of relief, 9S asked A2.

"Imp...... Do you want to die once and see? ”

A2's face suddenly became gloomy, and with her waist-length snow-white hair, it looked terrifying.

Couldn't she have friends?!

"Well~well~ you didn't say it."

9S waved his hand indifferently, A2 has threatened himself at least hundreds of times in the past three years, but he didn't do it once, he was used to it.

"Billy, what do you think after learning about us?"

"Speaking of which......"

As soon as Billy heard what 9S said, his eyes suddenly lit up, like a child who saw some precious child, and the sadness between his eyebrows seemed to have completely disappeared, and he asked directly towards 9S.

"9S, were you really created by humans?"

"Well, to be precise, we were created by humans as artificial beings, and we were created to fight against the mechanical life forms created by aliens, because our core is modified from the core of mechanical life forms, so to be precise, we are closer to mechanical life forms."

"Mechanical lifeforms? What's going on here? ”

"It all started in the year 5012 of our world, when the last human soul died ......"

"Wait, the humans of your world have perished?"

“……”

Seeing Billy's mouth open as if he was about to dislocate, and his face was full of shock, 9S thought that 2B should have just told Billy that they were androids, right?!

“…… Well, since you don't know anything Billy, I'll start from the beginning, and we have to start with 2003 in our world......"

Since that's all that has been said, let's just finish it. ’

9S thought helplessly, and then slowly narrated the history of Neil's world.
