This is a completely unfamiliar card.

On the screen was a human face, with its mouth wide open and saying something.

What the hell is this?

Mu Yuan's first reaction was that he was completely confused.

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

"Advanced psychological lie detection technology!"

Psychological lie detector?

Is this thing reliable?

Mu Yuan knew something about psychological lie detectors. In many movies and TV series, lie detectors were a magical thing.

But in fact, the use of this thing is very limited, and the accuracy is uncertain, let alone used as evidence.

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

This is similar to psychological criminal profiling technology!

During the interrogation process, if we can determine to a certain extent whether the other party is lying, it will definitely be of great help in solving the case.

As for the level of advanced psychological lie detection technology he had obtained, Mu Yuan was not sure.

However, considering the system's consistent performance, this technology should not disappoint me.

Anyway, the mystery will be solved soon, so Mu Yuan is not in a hurry.

The sixth card was slowly turned over, and it was a bottle of Thoughtstorm Potion—well, not bad!

Then there is the seventh card, another energy potion!

The eighth, blank card!

The ninth picture, high explosive bomb...

Mu Yuan's face turned dark and dark.

This is definitely the worst luck he has ever had since drawing cards, bar none.

After nine cards in a row, a decent skill was produced, and the level was only advanced.

Although Mu Yuan guessed that the psychological lie detection technology would be of great help to his investigation work, with just one technology, the psychological gap was still quite large.

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

Just as he was thinking about this, the tenth card was finally revealed.

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

Skill upgrade card (expert level).

Mu Yuan quite likes the skill upgrade cards.

But it's not entirely true how excited Mu Yuan was when he saw this card.

Take this time as an example, a skill upgrade card plus an advanced psychological lie detection technology, isn't it equivalent to having an expert psychological lie detection technology?

Other than that...except for those weird consumables, there is nothing else.

But it’s not entirely true that this card draw was a complete loss.

Not to mention the value of the advanced psychological lie detection technology, just this expert skill upgrade card, the mall price is 90 points of chivalry points, which is equivalent to making your own money back.

Calculated this way, the advanced psychological lie detection technology and other messy props are equivalent to... free prostitution.

But, why do I always feel a little bit unwilling in my heart?

At this time, the ten cards disappeared instantly, the prop cards entered the backpack, and the technical cards directly turned into data streams and entered Mu Yuan's mind.

After a brief pause, Mu Yuan finally figured out this advanced psychological lie detection technology.

In fact, this thing is... quite mysterious.

Compared with normal technology, this technology obtained by Mu Yuan is different, the style... is very systematic.

Just like odor identification technology, normal odor identification technology definitely requires equipment. Kemuyuan's odor identification technology does not require it at all, just wearing a nose is enough.

The same goes for this psychological lie detection technology. Normal psychological lie detection technology also requires equipment to detect the target person's heartbeat, pulse and other physical signs.

Kemuyuan's psychological lie detection technology can detect a person very well using only eyes, ears, hands and other sensory methods.

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

Of course, his perceptual abilities do not always maintain this super state, but only have such effects when he concentrates his attention.

Moreover, using this kind of bug-like perception ability consumes a lot of physical energy - although it is far from comparable to the consumption in the Thoughtstorm Potion state, it certainly cannot be maintained in this state for a long time, and it is not that

necessary.

Okay, these are all details! Don’t pay too much attention to them.

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

Detecting physical signs is all for lie detection services.

How to connect these representations with a person's psychological activities and speaking status.

This thing sounds simple, but in fact it is very complicated to implement.

Just like some people blush when they panic, but some people can lie without changing their face or heartbeat.

According to the theory of psychological lie detection technology obtained by Mu Yuan, anyone who lies will have physical symptoms.

The difference lies in whether you can discover these representations and how to organically relate them.

The psychological lie detection technology he has now acquired has reached an advanced level. If someone lies in front of him, more than 95% of people can be judged. However, there are some people who cannot judge, and it does not rule out that there are a very small number of people who will.

Let Mu Yuan make a wrong judgment.

The ratio of 95% sounds high, but the actual effect is just that.

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

And this 95% is almost... the same as the most widely used high-end lie detector in society.

This is actually normal. After all, it is only at an advanced level. Just like the advanced trace inspection technology that Mu Yuan obtained before, it is almost at the domestic expert level, and cannot be regarded as the top expert. Of course, Mu Yuan does not need to use equipment.

.

Mu Yuan's horizons have also been raised now, and he doesn't have much regard for high-level technology.

Didn’t I happen to draw a skill upgrade card just now? I just arranged it.

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

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

After he finished sorting out the extra information in his mind, a hint of joy flashed in his eyes.

Expert-level psychological lie detection technology is indeed much more powerful than advanced levels.

Not only did it further improve his perceptual acuity, but it also gave him a deeper understanding of psychological lie detection.

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

While his psychological lie detection technology has improved, his cognition in psychology has also made significant progress, as well as neurology...

After turning off the system interface, Mu Yuan still felt a little melancholy. After all, compared with the previous ten draws, the gains this time were really low.

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

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

Although he thinks so, Mu Yuan actually knows very well that when it comes to drawing cards, as the number of card drawings increases, the chance of winning a skill becomes lower and lower.

The reason is simple: the types of technology are ultimately limited.

Although this unreliable system has crammed in all kinds of unreliable technologies, as long as the technology cards do not appear repeatedly, there will always be a day when they are exhausted.

In the previous ten consecutive draws, there were basically two or more types of skills, but in the last draw, all the cards drawn were props, not a single technology card.

This time only one appeared.

There are various signs that the probability of winning technology is indeed decreasing.

But Mu Yuan won't be too disappointed. He has acquired enough skills so far. If he can't acquire any more skills from now on, he will be able to thrive in this world.

Moreover, with fewer technical cards being produced, the probability of item cards appearing is naturally higher.

Although prop cards are indispensable for cheating things like high-explosive bombs, infinity gems are also props, right?

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

His eyes suddenly flickered.

There is a saying called "What's the matter?"

Having such bad luck just now, does it mean that I have used up all my bad luck?

In the end, Mu Yuan failed to muster up the courage to try another ten consecutive strokes...
