This is a completely unfamiliar card.

The picture shows a human face, talking about something with its mouth wide open.

What the hell is this?

Mu Yuan's first reaction was to be completely confused.

When the name of the card appeared, Mu Yuan's eyes widened instantly.

"Advanced Psychological Polygraph Technology!"

Psychological polygraph?

Is this thing reliable?

Mu Yuan still knows a little about psychological polygraphs, and in many film and television dramas, polygraphs are a kind of divine thing.

But in fact, there are great restrictions on the use of this thing, and there is no fixed accuracy rate, let alone use it as evidence.

However, as far as the current field of investigation is concerned, this technology can still be used as an auxiliary means of investigation.

This is similar to the psychological crime profiling technique.

In the course of the interrogation, if it can be judged to a certain extent whether the other party is lying, it will certainly be of great benefit to the cracking of the case.

As for the level of advanced psychological polygraph technology that he obtained in front of him, Mu Yuan was not sure.

However, in terms of the degree of rebellion that the system has always exhibited, this technology should not disappoint itself.

Anyway, the mystery will be solved in a while, and Mu Yuan is not in a hurry.

The sixth card slowly unfolded, and it was a bottle of Mindstorm Elixir - well, not bad!

And then there's the seventh card, which is the Energy Elixir!

The eighth, blank card!

The ninth, high-explosive ......

Mu Yuan's face became swarthy.

It was definitely his worst luck since the draw, not one.

Nine cards in a row, a decent point of skill has been produced, and the level is only advanced.

Although Mu Yuan guessed that this mental polygraph technique should be of great help to his investigation work, there was only one technique, and the psychological gap was still quite large.

I don't know what the tenth card is......

While he was thinking about this, the tenth card finally opened.

When he saw this card clearly, Mu Yuan's mood was quite complicated.

Skill Upgrade Card (Expert Level).

For skill upgrade cards, Mu Yuan still likes it.

But to say how excited Mu Yuan was when he saw this card, it was not necessarily true.

Take this time as an example, a skill upgrade card plus an advanced psychological polygraph technique, isn't it equivalent to drawing an expert-level psychological polygraph technique?

Besides...... Except for those weird consumables, there is nothing.

But to say that this gacha is a complete loss, not really.

Not to mention the value of the advanced psychological polygraph technique, just this expert-level skill upgrade card, the mall price is 90 chivalrous points, which is equivalent to making yourself return to your original cost.

In this way, the advanced psychological polygraph technology and other messy props are equivalent to ...... White prostitution.

However, why is there always a little unwillingness in my heart?

At this time, the ten cards disappeared in an instant, the prop cards entered the backpack, and the technology cards directly turned into data streams and entered Mu Yuan's brain.

After a short pause, Mu Yuan finally figured out this advanced psychological polygraph technique.

Actually, this thing ...... It's quite mysterious.

Compared with the normal technique, this technique obtained by Mu Yuan is not the same, and the style is ...... Very systematic.

Just like odor identification technology, normal odor identification technology definitely requires equipment. Kemuyuan's odor identification technology is completely unnecessary, just bring your nose to it.

The same is true for this psychological polygraph technique, which also requires equipment to detect physical signs such as the target person's heartbeat and pulse.

Ke Muyuan's psychological polygraph technology only needs to rely on eyes, ears, hands and other perceptual means to detect a person well.

Therefore, correspondingly, because of the acquisition of this technology, Muyuan's vision, hearing and touch have been greatly improved.

Of course, these perceptual abilities of his are not always in this super state, but only have such an effect when he is concentrating.

And the use of this kind of BUG-like perception ability is also quite a lot of physical energy - although it is far from being comparable to the consumption in the state of the Mind Storm Potion, it is certainly not possible to maintain this state for a long time, and it is not that necessary.

Well, these are the details! Don't worry too much about it.

What really made Mu Yuan study carefully was whether this technology was reliable or not.

Physical manifestations are examined for the purpose of polygraph services.

How to relate these representations to a person's mental activity, speaking state.

It's easy to say, but it's very complicated to implement.

It's like some people blush when they panic, while others can keep their faces coloring and their hearts don't beat when they lie.

According to the theory of the psychological polygraph technique obtained by Mu Yuan, anyone, as long as he lies, will show signs of it.

The difference is whether you can spot these representations and how you relate them organically.

The psychological polygraph technology he has now acquired has reached an advanced level, if he lies in front of him, more than 95% of people can be judged, but there are also some people who can't judge it, and even a very small number of people will make Mu Yuan make a wrong judgment.

95% sounds like a lot, but that's exactly what it actually looks like.

As far as polygraphy is concerned, even ordinary people, without the help of equipment, can often tell whether others are lying.

And this 95%, almost...... It is almost as effective as the most widely used high-end polygraph in society at present.

This is actually normal, after all, it is only an advanced level, just like the advanced trace inspection technology that Mu Yuan obtained before, which is almost the level of domestic experts, and it cannot be regarded as the top expert - of course, Mu Yuan does not need to use equipment.

Mu Yuan's vision is also high now, and he doesn't look down on high-level technology.

Didn't I just draw a skill upgrade card, just in time?

Mu Yuan is a man of action, without any hesitation, he directly opened his backpack and used the skill upgrade card.

My mind was a little groggy, but I woke up after a few seconds.

When he finished sorting out the extra information in his mind, his eyes couldn't help but flash a hint of joy.

The expert-level psychological polygraph technique is really much more powerful than the advanced level.

Not only did he further improve his perceptual acuity, but also gave him a deeper understanding of psychological polygraphy.

To some extent, the promotion from advanced to expert level is more like a transition from a single skill to a technical system.

At the same time as the psychological polygraph technique improved, his knowledge of psychology also improved significantly, as well as neuroscience......

Turning off the system interface, Mu Yuan is still a little melancholy, after all, compared with the previous ten consecutive draws, this harvest is really a bit LOW.

He glanced around at the quail-like group of suspects, and sure enough, ...... Criminals have their own aura of bad luck.

The next time you draw a card, be sure to stay away from these people.

Although he thinks so, in fact, Mu Yuan is also very clear that this kind of thing is a card drawing, and as the number of card draws increases, the probability of winning the technique is getting lower and lower.

The simple reason is that the variety of technologies is limited.

Although this unreliable system is crammed with all kinds of unreliable technologies, as long as the technical cards don't recur, there will always be a day when they will run out.

In the previous ten consecutive draws, there were basically more than two types of technology, and in the last card draw, all the items drawn were props, and there was not a single technical card.

This time, there was only one.

There are signs that the odds of winning a skill are indeed decreasing.

However, Mu Yuan will not be too disappointed, so far, he has obtained enough technology, so he will not be able to obtain any technology from now on, and he can also mix well in this world.

Moreover, there are fewer technical cards, and the probability of item cards appearing is naturally higher.

Although prop cards are indispensable for high-explosive bombs, Infinity Stones are also props, aren't they?

Thinking like this, Mu Yuan felt that his fighting spirit had improved a lot.

His eyes flickered suddenly.

There's a saying that what's called?

If you have such bad luck just now, does it mean that you have used up all your bad luck?

In the end, Mu Yuan failed to raise the courage to draw again for ten consecutive draws......

......

Mu Yuan enjoyed a hearty lunch in the bureau at noon.

Although the lunch in the canteen of the Nanhua District Bureau is not necessarily better than that of the canteen of the Xihua City Bureau, it is easy to get tired of eating the same taste after eating for a long time, and it feels much better if you suddenly change the taste.

The same buffet mode has brought a lot of convenience to Muyuan.

However, the captain of the Xing Dalin team, who accompanied Mu Yuan to dine, was a little suspicious of life.

At this time, he realized that the breakfast in the morning, this Captain Mu had not fully played!

It's a pity that he can't say these thoughts, and he can't thank Mu Yuan in person.

After the meal, Mu Yuan continued to guard the case center until two o'clock, when Cheng instructed them to rest, and then came over to take over.

At this time, Mu Yuan was also a little tired, if Cheng didn't guide them anymore, he estimated that he would have to use the energy potion again.

But now that he is here, Mu Yuan can also save money, and he sneaks away to sleep very heartily.

One of the advantages of sleeping in a hotel is that you can think of it as if it were the middle of the night – the blackout curtains don't work too well.

By the time Mu Yuan woke up, it was already one o'clock in the middle of the night!

I slept for 11 hours!

And he was woken up by the alarm clock.

After a brief wash, dispelling the sense of chaos caused by a long sleep, Mu Yuan quickly rushed to the Nanhua District Bureau.

At this moment, the courtyard of the Nanhua District Bureau is lively.

Two black SWAT vans were parked in the courtyard, and two rows of well-dressed SWAT patrol officers were getting out of the buses, while Cheng Gui stood aside and talked to another policeman.

Although Mu Yuan couldn't name the policeman, he knew that he was from the patrol special police detachment of the Xihua City Bureau.

"Team Mu, you're quite punctual when you wake up! I'm going to call you after I've loaded all the suspects." ”

It's so depressing today, the keyboard is malfunctioning, the Z key is out of order, either you can't press it, or it's just a few ......
