In addition to Sima Aya's stand-in, there are other stand-in robots walking around, and some stand-in robots are sitting in the booth to work, and of course, there are also human engineers walking around or working.

It's a stand-in testing center in the northern suburbs of Denver, for engineers from country C, and no people from country A or other countries work here.

Before Sima Aya moved her new body, she saw that some mission briefings appeared on the robot's visual interface, and it felt like floating in the air in front of her:

Time: October 14, 2117, Denver City Stand-in Testing Center.

The City of Denver (City_Of_Denver), a merged city and county in the U.S. state of Colorado, is the largest city and capital of the state of Colorado.

Located on a plain adjacent to the Rocky Mountains, about 15 miles from the base of the mountain, Denver forms the core of the Denver-Aurora metropolitan area.

The National Census Service estimates that Denver had a population of 682,545 in 2015, making it the 19th most populous metropolitan area in the United States.

Special note: This is just the city of Denver in the past, and Denver now, which is very depressed.

In the visual interface, Sima Aya immediately saw the depressed city. The skyscraper-strewn metropolis is still there, but the bustle is long gone, the shops at the foot of the skyscrapers are closed, the streets are empty, and from time to time confetti flutters in the wind. Sima Aya knows that this is because the nuclear threat has not been lifted, and most of Denver's residents are still living in refugee camps in the township.

Special note: Less than 15% of people have returned to the city, and the briefing prompts: the law and order situation is not good......

After the briefing, when Sima Aya moved her eyes to the other stand-in robots or humans in the office, the visual interface would soon appear on the visual interface, or some attributes of that person, such as first name, last name, and model...... This made Sima Aya feel very novel, like watching a 3D movie.

Soon Sima Aya's stand-in could move, and it didn't take long for her to exchange names with the people and robots present. An engineer told Sima Aya that the stand-in she used was the latest X2117A, with a lot of newly loaded features, a higher intelligent version, and faster electronic nerve response, hoping that she would have time to do a good test and submit the test report on time.

Of course, the engineers at the test center didn't know that Sima Aya's mission in country A this time was not to test the performance of the stand-in robot for the test center.

Long before coming to country A, Sima Aya had already received a task, which was related to Yang Yiyi, but not only for Yang Yiyi:

Not far south of the city of Denver is a county seat, Englewood. Strange events have occurred in Englewood County: residents have disappeared, one after the other. According to known intelligence analysis, it is related to the disappearance of Yang Yiyi.

Sima Aya thought that if Yang Yiyi's disappearance and the disappearance of these residents were caused by the same reason, then it was definitely not the intelligence agency of country A that arrested Yang Yiyi, and Yang Yiyi was probably in the depths of another, unknown and strange (commemorating Huang Yida, the word "weird" is said to have been coined by him). It could be much worse.

At this moment, Sima Aya couldn't wait to fly to the places where the incident occurred in Englewood County, immediately find out the original culprit, torture him, and then find Yang Yiyi...... Thinking of this, Sima Aya's thinking paused, she was a little afraid, afraid of the ending that might be shown in front of her: she hoped that she was still alive, still the same warm, soft, and beautiful, not a mutilated, unrecognizable ...... Like those that Sima Aya has seen countless times at the scene of the crime in the past, people who were once fresh and lovely.

Thinking of this, a tear had already secretly appeared in Sima Aya's eyes. She subconsciously wanted to wipe her tears with her hands, but at this time, what appeared in front of her was only an unfamiliar mechanical arm - an arm far away on the other side of the ocean.

The hand far away in the sky couldn't wipe away the tears in front of her, she could only let the drop of water slip down and turn into a faint salty taste in her mouth.

The 1 billion stand-in robots provided by country C for country A do not have human appearance or human skin, all of them are "robots that look like robots", full of metal texture, of course, mainly to save costs in mass production. Now, the streets of country A are full of robots with this sense of machine.

Sima Aya has long wanted to have such an immortal body. If there is any danger in the process of rescuing Yang Yiyi, she can fight to the death at any time. If not, you can do it again soon. When Sima Aya operated this stand-in, there was a thrill of having infinite lives, which shone secretly in the depths of her mind.

Stand-in test engineer, Xu Xiaoting. This is Sima Aya's new identity.

A day later, "Xu Xiaoting" came to Englewood County. One of the benefits of being a stunt-in test engineer is that she can drive the stunt in anywhere, and of course, "anywhere" does not include military-controlled areas.

According to known information, there is a remote farm in the southern suburbs of Englewood, and the farmer Smith and his family of three are missing. There are also rumors in the local area that they were captured by aliens, because, more than 20 years ago, the farm had a series of corn field circles in a week, suspected to be committed by aliens.

Smith's farm is not far from the county seat, only 5 miles, and after Xu Xiaoting was fully charged in the county seat, it didn't take long for her to run to the farm.

From Denver to Englewood, all the way, he or she came by running.

The X2117A stand-in robot can enable a self-guided running mode. In this automatic mode, the operator can be at rest, do not need to do anything, do not exert the slightest effort, and even get a good night's sleep.

Therefore, to operate the X2117A stand-in, if the road is not very long, no more than 600 miles, there is generally no need for a car to travel, just run forward.

When Xu Xiaoting came to the farm, it was 2:00 a.m. local time, the full moon hung high on the quiet farm, and under the full moon, at the end of the field, a lonely vaulted wooden house could be faintly seen.

When Xu Xiaoting approached the wooden house, she found that the wooden house was very tall, as high as a two-and-a-half-story building, giving people a strong sense of oppression.

However, seeing the bright full moon, Xu Xiaoting felt a touch of refreshment again - in China, under the cover of heavy haze, this beautiful scenery exists almost exclusively in books. Beautiful and eerie.

Xu Xiaoting saw the cordon that the police had set up around the house. She took a deep breath and crossed the cordon.

At this point, the visual interface of the double prompts her if she needs to turn down the intensity of her neural induction to avoid being frightened. Because, depending on her current heart rate, it would be good for her to turn down the intensity of the neural induction.

Xu Xiaoting thought about it for a while and decided that as long as the night vision function was turned on, experience told her that lowering the intensity of neural induction, although she could avoid being frightened, would also lead to unresponsiveness, and she could not respond quickly to the danger in front of her.

Xu Xiaoting used the night vision switch that currently chooses the visual interface, and the black field of vision turned into fluorescent green.

Xu Xiaoting took some time to try around the wooden house, and the doors and windows were locked. She was hesitant to break in. At this moment, a hole in the north wall of the wooden house caught her attention: it was a huge hole, more than a person in diameter—the scene of Yang Yiyi's disappearance immediately came to her mind.

Xu Xiaoting entered the farmhouse through the hole, and soon found that the wall where the hole appeared was the wall of the bathroom, which was the same as when Yang Yiyi disappeared, which was the wall of the bathroom, and from experience, it was unlikely to be a coincidence...... Xu Xiaoting remembers the intelligence information she had read before, in recent days, hundreds of missing residents have almost all occurred on the night of a thunderstorm, the scene is a bathroom, and a big hole has been broken in the wall.

(Under the cover of thunder, heavy rain and night...... This is the most primitive wisdom of human beings! Xu Xiaoting stood at the mouth of the hole and couldn't help but think, she felt for no reason that in the darkness around her, something was staring at her with bated breath.
