Anna was startled by the unfamiliar sound overhead, and she raised her head stiffly to see a large snake almost five feet (1.5 meters) above her head coiling around the beams of the house.

Even a person like Anna who is very afraid of snakes has to admit that this is a very beautiful big snake, the snake scales are as white as snow, rich in light color, but the body is surrounded by a black invisible mist, the mist is swaying like a flame, and the white snake in the reflection is a little illusory, and the pair of black and shiny snake eyes are inlaid with a pair of golden vertical pupils, majestic and noble but cold and ruthless.

At this time, the big snake was spitting scarlet, and the hyacinth looked at Sister Anna with interest.

Anna didn't know why she read emotions from a snake, she just had a feeling, thinking of the hoarse voice she had just heard, and the answer was obvious.

The question just now may have been asked by this snake, which is a talking snake.

When she realized this, the girl's eyes widened, and in addition to the shock that snakes could speak, a fear of the mysterious world from ordinary people grabbed her heart like an invisible hand, and she didn't know what to do for a while.

Anna had no choice but to hold her sister in her arms firmly, trying to draw even a trace of security and courage from her sister.

However.....

Even after being held so hard, the sleeping sister was still not awakened, she just groaned in pain.

Anna, who realized that she had hurt her sister, quickly let go of her hand, but she heard the snake speak again.

"She seems to be dying, and I smell death in her."

At this moment, the anger caused by the love for her sister suddenly rose from Anna's heart, anger overriding fear, and Anna raised her head and glared at the snake that was talking nonsense.

"You're dying, Belle."

"Hehe, I'm sorry, I think this young lady you misunderstood what I meant, I mean this child is sick, I don't believe you silently her forehead."

After that flash of anger, Anna realized that she had spoken out against the mysterious talking snake, and she was afraid for a moment, not knowing what to do if the snake was provoked to attack them, but to her surprise, the snake seemed unexpectedly gentle, and it even kindly explained to her.

Hearing this, Anna immediately reached out and touched her sister Belle's forehead.

It's piping hot to get into.

Belle was really sick, she had a fever, and it was very bad.

At this moment, Anna was really panicked, no matter how mature and calm she was, after all, she was only ten years old, and her lack of experience made her a little helpless for a while, but they were still trapped in this broken basement, even if they wanted to find someone for help, they couldn't find anyone.

Wrong....

Anna jerked her head up and looked at the illusory white snake with a pitch-black mist wrapped around its body.

There is no one to turn to, but there seems to be one for the snake.

.............

On the other side, in the demon carriage, watching the picture from the projection technique, Hong covered his mouth in surprise.

The snake that brought back not only the picture, but even the sound, so Red could clearly hear the twin sisters chatting in the basement.

Apparently, the two sisters were actually locked in the basement by their father, the clothing store owner.

But why, ask what kind of father would do to his own daughter, even if it is a tiger in the forest, and still not hurt his own child.

Hong, who admires her father very much, can't accept the fact that there is such a cruel father in this world for a while, she has assisted the police station in investigating cases for so many years, and she has seen a lot of various murderous cases, even if those bloody and terrifying murder scenes are scary, they can't scare her as a werewolf, but this kind of blood cannibalism case makes her feel cold and a little cold.

But in the end, it was a wizard, red crossed her hands and hugged her arms, she quickly adjusted her mentality, calmed her mood, and then turned her head to look at the peerless beautiful young man with his eyes closed.

"Professor Merlin, how the hell did you find out?"

Now that Professor Merlin's previous speculation had been proven correct, Red wondered how he had discovered that something was wrong with the shopkeeper.

The werewolf girl recalled the expressions of the shopkeepers and felt that his acting skills were still quite good, at least Hong herself had never doubted the shopkeeper at all.

And Professor Merlin had clearly said that he didn't know how to investigate cases, but he didn't expect it to be so powerful, but she really believed his nonsense before.

Thinking of the scene when Professor Merlin asked for help before, she herself was quite unhappy, and the roots of her ears turned red with shame.

Hearing Red's inquiry, Merlin withdrew a bit of consciousness from the illusory snake in the distance, and while he continued to observe the sisters, he smiled and answered the werewolf girl with a face full of curiosity.

"It's just some simple psychology."

He replied with a modest smile.

"Psychology?"

A question mark popped up above the red head.

Although it can't be compared with Cinderella's pervert, but Red is indeed a primary school bully among other students, and she has heard of psychology to some extent, which is a recently emerging subject, but except for special schools that specialize in training police, detectives, and psychiatrists will teach this subject, other schools rarely teach it, at least Aldrichie does not offer this kind of course.

"Well, it's psychology, to be precise, the interpretation of micro-expressions in psychology."

Merlin nodded and explained.

In his previous life, micro-expressions were popular for a while, and at that time, he was also in the second middle school period when he was constantly gnawing books in order to improve his traveler manual, so he also found a few books on micro-expressions and read them.

Of course, if you can really apply it just by reading the book, then the master of micro-expressions will be all over the place, and the reason why Merlin can put the theoretical knowledge in the book into practice is entirely because the original owner left him a foundation in psychology 70.

Well, well, it's level 75 now.

Merlin glanced at the hint in his dark vision.

[You have successfully solved a case with your knowledge of psychology combined with knowledge from another world, and your psychology has improved. 】

[Psychology +5]

Just the initial mastery of this so-called micro-expression made Merlin's psychology rise by 5 levels all of a sudden, which surprised him, and by the way, he continued to thank the middle two diseases in his previous life, this otherworldly knowledge is really easy to use.

This traverser's manual is really not prepared in vain, it really deserves to be me, I was prepared early, and it is capricious to bring my own gold finger.

His heart swelled slightly, but when he saw the werewolf girl on the side who was more curious, he didn't sell much, and explained a little.

"Did you notice the look on the shopkeeper's face when I asked him earlier? If you look at his expressions, you can see that there are many flaws in his answers. ”

Red was even more blindfolded, she frowned and recalled carefully, it didn't seem to be a problem.

"For example, don't you think it's a little awkward for him to ask me to find his daughter's yes expression?"

Seeing Red's confused look, Merlin gave a hint.
