I'll explain how this helper unit works – for example, how it holds this data.

First of all, the auxiliary unit itself only has the ability to calculate instantaneously and the caching ability that can only be used to memorize temporary computing data, but does not have the ability to store memory, and all medium and long-term memory depends on the ability of the brain itself.

Second, the brain itself has a limited ability to remember information (according to actual measurements from Bell Labs, most people can only recall about 200 trillion pieces of information. And the auxiliary unit does not expand this data, but the auxiliary unit can effectively use the memory ability.

For example, if the black car is present from the second to the eighth observation, then the data recorded by the second observation is like this

[Time code], black car, the first parking space. (The outline of the car is recorded separately in a separate data line)

And that's what happens when the data is recorded from the third to the eighth

[Time Code], the same as [Time Code of the Second Observation]

The third to eighth times are the same as the second, but the auxiliary unit is able to rewrite the information and reduce the amount of brain capacity needed for memory without losing the core information. Thus, the memory capacity is improved without increasing the memory capacity.

When recording images, the auxiliary unit rarely records the image itself directly (because the memory consumption of the picture is too large), but records the general outline on the basis of some additional detailed features, such as this.

It is a black Chevrolet sedan (rough outline) with a license plate number of ***** (detail feature) and a certain brand of tires on the left wheel (further detail feature).

If all of these were copied, and the rest of the parts were unrecognizable, Thousand Feathers would not be able to make out the details, because all the details stored in the auxiliary unit matched. But given the randomness of the details of the auxiliary unit's selection of memory, this possibility is close to zero – as long as the Chevrolet and the memory information match, then it can be considered the same car.

"What's wrong with you?" Gray Yuan Ai inadvertently glanced at Qian Yu, only to find that his appearance didn't seem quite right.

"I'm not sure, but..." Qian Yu hesitated for a moment before speaking. "I have a feeling that someone is following us."

"What?" Ashbara was stunned.

"It's possible that it was just an accident," Qian Yu whispered. "Let's see...

。。。

Chiba carried a tray and walked to the empty seat opposite Ashbara's seat. "It's all together."

"Thank you." Gray Yuan nodded, picked up a hamburger, and ate it.

Qianyu was also about to eat the burger he ordered, but he noticed a man walking in at the door.

This guy ... Chiba's expression was wonderful.

This man is Caucasian, and if you take the counter as a reference, he is about 1.85 meters tall - in Japan, a 1.85 meter is quite a prominent height.

But if it was just that, Qian Yu wouldn't be so surprised. There are also many Americans in Japan, and there are many people in the United States who are 1.85 meters tall.

However, not every American in Japan who is 1.85 meters old will have such developed muscles...

The man wears short sleeves and trousers, whether it is the shape of the muscles on the strong arms, although they are not protruding much, the muscles are angular, or the shape of other exposed parts such as the neck, indicating that he has a very low personal fat percentage - about 11%.

Other than that... The shirt on the right side of his waist is a little bulging, and from the shape it can be understood as the handle part of a pistol.

Gray Yuan Ai seemed to see that there was something strange in Qianyu's gaze, and she also looked at the man, but in the next second she turned back again.

"Who is that?" Gray Plains asked. "I think he's anatomically weird."

“？” Thousand Feathers raised an eyebrow.

"The body fat percentage is very low, so there is a high probability that they are manual laborers, but how can a Caucasian person come to Japan to work as a trainee?" Gray Yuan said. "Considering the muscle ratio and muscle mass of his upper and lower body, as well as his age, he is neither a bodybuilder nor a foreign aid such as football or baseball, but more like a physical worker who relies on the strength of his upper limbs."

At this moment, the man took money out of his pocket, but a key was suddenly taken out of his pocket.

The auxiliary unit captures the license plate identification on the key - Chevrolet.

"Cut..." Qian Yu frowned.

“？” Gray Yuan Ai obviously realized what Qian Yu had discovered, so he made a questioning expression.

"Chevrolet sedan!" Chiba does lip shape.

“！” Ash Plains was stunned.

Just then, Conan handed over a piece of paper.

Chiba looked at Conan and glanced at the piece of paper after returning the notebook and pen to Hoshima.

"Be careful of that man and the black Chevrolet he parked outside the studio, it's not good."

Chiba glanced at the note and wrote it as a ball, then gestured with her other hand to make an "OK" gesture.

。。。

Ten minutes later, the group walked on the way to their apartment on Hoshima.

"When did you find the problem?" Qian Yu walked beside Conan and asked softly.

"Do you remember that during the day, there was Sister Kiko who activated it urgently before the yellow light turned red?" Conan said. "There was and was only one lane that could and could only turn left, and we didn't move at the green light. But they didn't honk our horns at all, which means they didn't want to disturb us at all—isn't it strange? And for some time, that car has been on the same route as us, which is weird, isn't it? ”

"In other words, Sister Kiko noticed it at the time, right? . . Qian Yu muttered. "No wonder she's looking at the car instead of the road ahead when she turns the corner...

"Anyway, I think something is wrong," Conan said solemnly. "It's a good thing you're still carrying your school bag and your umbrella is there. Cheer up, I'm worried that something will go wrong tonight - especially on our way back from watching the anime. ”

"I see." Qian Yu nodded.

"If something goes wrong, don't think about fighting them, just run." Gray Yuan Wai walked to the other side of Qianyu at some point and said. "There should be 3 people on the other side."

"Why?" Chiba and Conan looked at Gray Plains together.

"He didn't eat in the restaurant just now, but ordered takeout - the total calorie value of these takeaways is 2,300 kcal, which is impossible to provide enough energy for four people, and it is impossible for two people to maintain such a perfect body shape if they consume 2,300 kcal."

"We're here." At this moment, Hoshima said. "The apartment on the far left on the third floor is my room."

"Is the light on?" Mitsuhiko wondered - as he said, the lights in that apartment were on.

"That's right," Hoshima nodded. "A couple of my colleagues also have keys to my room so we can stay up all night playing mahjong together."
