Two rows of tall pentagonal maples fill the sides of the street, and the maple leaves are half red, these giant maple trees were a gift from the human government as a symbol of friendship when the pioneers established Habitat 021. Standing right in the heart of Habitat 021, there are very few human activities here, most of which are robots.

The buildings on the long street are very different, but the water is full of skyscrapers, and these pentagonal maples, which average more than 20 meters, look very small here.

Chris watched it all through the porthole, the scenery familiar and unfamiliar to him. Having lived on this street since he was a child, he knew all the buildings here, but he had never been here since that incident.

The autumn breeze is bleak, and the autumn leaves are accumulating, and the ground is covered with a thick layer of red. Occasionally, human children, under the guidance of their parents, collect more complete maple leaves on the ground. The child clamped his clothes tightly, and a warm smile spread on his little face that was red from the cold.

"I miss it, Uncle Chris." Xiang drove the flying machine to the mountain, flying along the lowest path. He glanced back at Chris, who was on the side.

He had removed the disguise from his face, and although the wrinkles were still there, the wrinkles between his eyebrows and eyes had almost disappeared. It can be seen that the facial features have also been slightly adjusted before. The body has also become straight and tough, losing the old appearance of the dragon clock before, and recovering a little heroic. A dark gray uniform was comfortably attached to him, and some of them looked so natural. It's almost the same as the picture that Elfa gave him, and there is a sense of not being angry and arrogant.

Chris didn't speak, just nodded and looked out the window. With his face reflected in the porthole, he sighed slowly, how long had it been since he had done this.

The aircraft came to a steady stop in front of the Security Bureau building. In Habitat 021, which has a population of millions, there is only one government department responsible for policing. It is precisely for this reason that the building in front of the Security Bureau can accommodate tens of thousands of people at the same time.

"Let's go." Chris opened the hatch and straightened his clothes, his gray hair shiny behind his head. Although the old man is old, he is also a branch of the Security Bureau.

"Xiangshan, remember what I said to you." Chris strode in.

The entire hall, except for the two identity gates in the center, is full of white. Directly opposite hung a large Security Bureau badge on the wall, and the entire atrium was hollow, with sunlight shining through the glass in the dome.

"Please confirm your identity." The cozy electronic sound echoed throughout the hall, and two blue rays of light shot out from both sides of the turnstiles, quickly enveloping Chris's body.

A holographic display appeared in front of Chris, which clearly stated that Chris's vital signs were deceased.

Suddenly, a shrill siren sounded, and the glass curtain walls around the gate were instantly covered with a thick layer of mist, isolating Xiangshan from the outside. Immediately afterwards, the steel plate was quickly lowered, and the dome was also covered with a thick layer of metal.

The originally bright hall was now shrouded in a blinding red light. Dozens of elevators on the inside of the hall descended wildly, and in the blink of an eye, hundreds of people had already appeared in front of them.

"Elfa! What's going on! Xiang Shan frantically yelled at the communicator, this scene has never happened.

"Elfa!" Xiang Shan called Elfa again and again, but Elfa, who was in charge of the Sky Eye of Habitat 021, was disconnected at this moment.

"Look! Isn't that Chris? ”

"No way, he should be dead!"

"It can't be fake, right?"

There was an uproar in the crowd, Chris had been one of the most famous detectives in the Security Service, and he had worked with many humans and robots, as well as the stress response units he had brought out due to his age.

Despite this, everyone turned their guns on Chris.

"Who are you?" The leader was a cyborg with a thick layer of black metal, and his eyes were staring at Chris in front of him.

Chris shrugged his shoulders and pulled out his former work card from his bosom, which contained Chris's photo album, fingerprints, and a series of things to prove his identity. "Home Like, I'm Chris."

The robot's eyes read the information on the work card, but still frowned slightly: "Impossible, Chris has already been confirmed dead in the explosion ten years ago." ”

The atmosphere at the scene was a little tense, especially in the eyes full of red and the shrill sirens, as if there would be a clash in the next second.

Chris took two steps forward gently, and his hand pressed against the stress response force in front of him: "Hey, Zhang San, remember me?" So you're still a hairy boy, okay! Now they're all mixed with the squad leader! ”

The man known as Zhang San looked at Chris vigilantly, the muzzle of the gun in his hand drooped down slightly, and asked suspiciously to the robot led by him.

The robot in charge shook his head slightly, and it was obvious that he had seen Chris before, but it was a little unacceptable for a while.

"Bring him up." The cyborg tilted his head slightly to look at the dark red light on the communicator. The various levels of communication channels in the Security Bureau have their own colors, from light to dark, but this is the first time he has seen the highest level of communication signal in dark red.

The mechoid nodded, and reached out a hand to press it down against the void. The red light, thickened steel plates, and fog that only appear in response to emergencies disappeared in an instant. As if it had never happened.

"Zhang San, you take the people of your group to control him and send him to the office on the top floor." The robot tapped his finger up slightly, and then evacuated with the rest of the people.

As soon as Xiang Shan saw that the security bureau was back to normal, he immediately rushed in, just in time to see Chris being handcuffed and taken to the elevator by a group of stress troops in black uniforms.

He hurriedly stopped a robot: "What happened just now?" ”

"Chris, do you know?" The robot lowered his voice and said to Xiang Shan: "That legendary detective suddenly appeared today, but it seems that he has been summoned to the top floor. After saying that, the robot hurried back to the group.

"The top floor?" Xiang Shan muttered softly, the top floor had always been unopened in his impression. He had asked Elfa more than once, but as one of the masterminds of the Elfa Security Service, he had no permission to read this information.

"Boss." Number Three walked over, and he handed the document in his hand to Xiang Shan's hand.

Xiang Shan nodded and took the paper. After a casual look at it twice, he threw it on his desk: "Can you connect to Elfa's channel?" ”

Number Three shook his head: "After the Security Bureau entered a state of emergency, Elfa was forced offline. ”

Xiang Shan gently twisted the swivel chair and stared at the window in a silent daze.
