Sweetheart listened to Yu Chirong's tone, and had an indescribable strange feeling, she faintly felt that whether Lisa died or disappeared, it was a very mysterious thing, and even an ulterior thing.

How big is Wei Chi's family, and Wei Chirong is a senior superintendent, if you want to track down the whereabouts of a little girl, you can see the dead and the corpse, and you won't have a clue at all, right?

She didn't dare to ask and knew that she shouldn't ask, if Wei Chirong wanted to say something, she would always take the initiative to say it, so she just said sadly: "I'm a little ...... Regretful. ”

"It's nothing, it's all in the past. Wei Chirong smiled, and suddenly opened the black box in his hand, which is not an exaggeration.

Sweetie looked curiously and saw that the black box was divided into three layers, and the top layer contained a pair of white gloves and several neatly stacked small bags that were often seen in detective films.

In the middle layer are all kinds of tools, brushes, tweezers, cotton swabs, flashlights, etc., everything is placed in its proper place, and there is no mess at all.

The bottom layer is a few bottles of liquid or solid containers, a spray bottle, Yu Chirong took out the spray bottle, and the sweetheart asked: "What is that?"

"How about a little magic trick for you?" Yu Chirong suddenly raised the corners of his lips, like a cunning cat playing with its prey.

Sweetheart, the curious little milk cat, was completely attracted by the mysterious atmosphere at the moment and the delicate toolbox in Yu Chirong's hand, so much so that she forgot about it and nodded happily: "What kind of magic?"

Yu Chirong closed the black box, and suddenly sprayed the liquid in the spray bottle in his hand to the ground and around.

In an instant, a little firefly began to appear in the darkness, weird and beautiful, like the starry light on the "Tree of Life" in "Avatar", and like a fluorescent jellyfish on the edge of the Japanese sea, the sweetheart was stunned, and asked with wide eyes: "What is this? Why does it glow?"

"It would be scary to say it. Wei Chirong put on special sunglasses so that he could identify those marks more clearly, and he said lightly, "The places that glow are all bloodstains." ”

"Ahh!!!h

Qing Lang is right, this place is indeed very unclean!!!

"Why is there so much blood? Why is this blood turning blue?"

"You're a hundred thousand whys. Wei Chirong raised his eyebrows, "I love to be a curious baby so much, it's better to follow me as a ** and learn criminal investigation." ”

Sweetheart thought about it, wouldn't that be in and out of a lot of murder scenes?

"I just want to know why it glows...... "Curiosity filled with curiosity, she pleaded, "you sue me." ”

Wei Chirong smiled and explained: "This liquid is called luminol reagent, also known as luminous ammonia, and the luminol component in this reagent can react to heme and produce blue-purple fluorescence. No matter how long the blood is, or no matter how scrubbing it is, spraying it with this stuff will immediately indicate it. ”

"Sounds so ......profound," Sweetheart sighed with heartfelt emotion, and couldn't help complaining, "My chemistry has been returned to the teacher, what is this...... Ammonia, very fun look. ”

"Of course it's not for you to play with, it's a respiratory irritation. Wei Chirong reminded.

Sweetheart watched quietly, Yu Chirong immediately put on gloves and took out cotton swabs, gently wiped them in several places where the fluorescence was obvious, and then put them in a sealed bag, his movements were extremely delicate and careful, ordinary people couldn't do such a meticulous and time-consuming thing.

"These places are very dark, does it mean that there are a lot of blood stains in these places?"

"Pretty much guessed. Wei Chirong explained in detail, "There are two possibilities for the blood to be splattered here: 1) the blood stains have been wiped by someone and changed the original trajectory, and 2) someone has injured an artery here. If an artery is cut, blood tends to splatter, while venous bleeding can appear dripping. How to tell if it's arterial or venous blood is in the few places I took before, and you should be able to see that those drops are obviously dripping. ”

Sweetheart, hearing these theories for the first time, was really interesting and mysterious, and she asked, "Do you think these drops of blood were left by your sister?"

"It's up to the test, and it's been a long time, so I don't know if it's still detectable. Yu Chirong took off his sunglasses, put away the black box, and said in a deep voice, "Let's go." ”

Sweetheart was surprised, there were so many things scattered here, shouldn't he look for something carefully? Maybe there would be a clue left by Lisa!

As if to guess what she was thinking, Wei Chirong said: "Judging from the size of Lisa's shoes in that photo, the time when she appeared here should be when she was five or six years old, do you think that one of the books and miscellaneous items on the ground may be used by a five or six-year-old girl?"

"......Yes, too," Sweetheart scratched her head, "You have such strong reasoning skills, do you need a vegetarian like you?"

"It's just a little speculation, you can do it, and I'll show you how to analyze some of the problems if you want. ”

"But the pocket watch was found here, and the little shoe, and I was always worried that Lisa would have something else left here. ”

"You've found what you should have found. Wei Chirong replied lightly, he raised his watch, and suddenly invited, "Are you free for the evening?" As a thank you, I would like to invite you to dinner. ”

Sweetheart was stunned suddenly, this topic changed too quickly......

As if to guess that her doubts were still stuck before, Yu Chirong smiled dumbly: "You are very persistent about what you want to know, what do you want to know, why don't we talk about it later when we eat." ”

"I think you're mysterious. "Why do you say, 'I've found everything you should find?' If there's some secret in it that you can't tell me, you don't want to say it." ”

"You're a very upright person. Wei Chirong didn't care about the sweetheart's almost "questioning" tone, but said without hesitation, "You should know that the two Guangzhou, Hong Kong and Taiwan, all the way to Southeast Asia, are convinced of many things and things that they have in the dark. ”

"What the hell are you talking about?" Sweetheart shuddered inexplicably, it was really awkward to say such things in such a place!

Or we can put it another way -- it's the soul. Wei Chirong subconsciously took out his gold watch and played with it, and said quietly in a deep and unfathomable voice.
