The underground factory is located in the basement of the headquarters building of CR Home Robotics, and as soon as you enter it, you can see hundreds of tall and thin humanoid robots standing upright.

Susan. Dr. Crow pointed to these robots and introduced Leng and Naughty Anna, "These are the latest robots developed by CR, the HF-6 household robot. They have more advanced comprehensive performance than previous generations, and their autonomy is also more powerful. ”

Fang Leng and Little Naughty looked at these new HF-6 models, the HF-6 models are obviously more technological than the previous appearance, the HF-6 models are basically white alloy torsos and heads, plus black alloy limbs. The styles that I saw in the area of the company building before were diverse, but the colors and shapes were obviously not uniform, and this HF-6 was a completely different shape. This new type of robot is more advanced and avant-garde.

"So since these robots are more autonomous, they must also abide by the three laws, right?" Fang Leng watched as these HF-6 robots did not respond to Susan. Dr. Crowe asked.

"Of course, the three laws are the core programs that must be implanted by the HF series robots. First Law: Robots must not harm an individual human or stand idly by while witnessing the danger to which the individual human will be exposed. Second Law: A robot must obey a command given to it by a person, except when that command conflicts with the first law. The third law: Robots should protect their survival as much as possible without violating the first and second laws. These three laws are implanted in the computer of every HF series robot, and the HF-6 model will perfectly abide by these three laws. "Susan. Dr. Crow also emphasized the content of the three laws of robotics in passing.

Suddenly, a voice came, and at the same time, a middle-aged man with brown hair and wearing a researcher's white coat walked towards him.

"Hi, Dr. Crowe. Are you visiting here with friends? ”

Susan. Dr. Crow turned to look at him sideways and said, "Oh, Gerald, you're still here to debug. These HF-6s can already be said to be foolproof. ”

This researcher is one of the three chief scientists of CR company, Alan A. Dr. Gerald.

Dr. Gerald smiled, "After all, these robots can be said to be the long-term effort of us and Dr. Sheffield, and I can say that I love them very much. And there is no such thing as perfection in technology, and only continuous exploration can move forward. ”

Susan. Naturally, Dr. Crow has nothing to say: "You are so good, and the repeated observation of scientific and technological achievements is the spirit of the chief scientist of CR Company." By the way, is the Athena system okay? ”

"That's fine. Athena has always been stable, I have never seen such an advanced program system. Okay, I'll go to the reference room now. You and your friends take your time to visit. "Alan. Dr. Gerald walked to the elevator and left.

Susan. Dr. Crowe continued to talk about Leng and Naughty.

"Although the HF series robots are implanted with the three laws, in order to ensure that all the robots, especially the HF-6 program, are updated in a timely manner, these home robots are connected to the 'Athena' system. The Athena system is the blue data-like artificial intelligence system with a female voice that you have been seeing since entering the building. Its core device is located near the top floor of the building, and then connected to satellites and other robots through a signal tower transmitted to the top of the building. With the Athena system, the behavior of robots such as HF-6 can be monitored and updated at any time, ensuring that the robots are absolutely reliable. ”

"There are thousands of HF-6 robots here, and 30,000 in other parts of Chicago. There are also tens of thousands of other HF series models. You can take a closer look, don't worry, these robots don't look like metal but they're safe. "Susan. Crowe said to Fang Leng and Little Naughty.

Fang Leng had some more conversations with Dr. Crow, and the mischievous Anna walked in with great interest to observe these HF-6 household robots.

The alloy shell of these HF-6 robots is very smooth, and the white torso and head are in harmony with the black limbs. The robot's head has two eyes, and the eyes are like those of a camera.

From the appearance, you can deeply feel that CR and Susan. Crowe, Owen. Sheffield, Allen. The efforts of Gerard and other scientific and technological personnel.

After some visits, Fang Leng and Little Naughty finally said goodbye.

Susan. Crow sent the two men out.

Walking to the entrance on the first floor of CR, Dr. Crowe said to the two men, "You're going to be in Chicago for a while, so if there's anything you need to ask me, please ask." I'm very familiar with Chicago. This is a business card, if you have time, you can come to my house. You're welcome. ”

Fang Leng stepped forward to save her before, and of course, this doctor was also very friendly and polite to Fang Leng and Xiao Naughty.

"This visit is with Dr. Law." Fang Leng said politely to Dr. Crow.

At this moment, the three of them were attracted by the square in front of the building.........

I saw several guards standing in the square and surrounding one place.

There seems to be a man lying there!

The trio noticed that something was wrong, and Susan. Dr. Crowe's face changed dramatically, as if she knew the man well.

When I came closer, I saw an old man with a white beard lying here, bleeding from under his head, and wearing a white coat for scientific research.

"Dr. Sheffield!" Susan. Dr. Crowe was astonished.

After hearing this, Fang Leng looked at the dead man on the ground, this person's name was Sheffield, could it be the one who was the first of the three scientists.

The little naughty beside Fang Leng also took a breath of cool air and exclaimed, "Isn't this the Dr. Sheffield?" How could he ........."

The mischievous Anna used to watch Dr. Sheffield's tech shows, so she naturally recognized him.

Fang Leng looked at the corpse on the ground, although it was in the square, it was not too far from the building.

When I turned my head to look at the building, I saw a large hole in the glass wall of a room in the middle of the building. It appears that Dr. Sheffield fell from there and died.

Looking at the color of the blood on the ground, it seems that the death has not been long ago, so this is what happened during the period of the visit just now. 10
