Guna waved her hand to the side.

A female guard came over and said coldly towards Song Kai: "Half a month ago, we received a call for help from the city lord here, he said that there was a murderous demon in this place, and he specialized in hunting children, and he also dug out the hearts of children and ate them. The point is that the other party is very cunning and has no trace at all. We, Goddess Guna, were originally in retreat and cultivating, but she cared about the people, so she immediately rushed over with the people from our Goddess's Mansion and came here. When we were investigating, we found that there was a residual demonic aura at the scene of the child's death, so we concluded that it must have been done by the demon beast, and the strength of this demon beast was very strong, and it should have turned into a human form, so we were nearby, all the way to control, specifically looking for the demon beast. Sure enough, I caught you today. ”

Song Kai understood, and he said speechlessly: "However, we are really the first day to come, so let's take me to the nearest site to have a look." ”

"Do you want to escape?" said the maid dismissively.

At this time, Guna stood up and said, "Let him go, pick two people, and go together." ”

"Yes, Goddess. The female guard immediately let go of Song Kai.

Gu Na looked at Song Kai and said, "Do you know why I agreed to your request so easily?"

Song Kai immediately said: "It must be the goddess who found out that I am very safe, and I don't look like a bad person at all." ”

Gu Na pursed her lips and said, "It's the first time I've heard of the term "look safe, but the reason why I let you go" is because your strength is too low, so there is no difference between letting you go and tying you up, and in addition, I think what you said about the motive for committing the crime is quite right, and I also want to take you to see and investigate clearly, what is your motive for committing the crime." ”

Song Kai shook his wrist and said, "Okay, let's go." ”

Bai Yuezi was thrown into a room, and the bronze mirror was obviously very powerful, directly imprisoning Bai Yuezi, and he couldn't use even a trace of demonic power.

The four of them walked towards a house in the city.

This city is very large, but the inhabitants in it are very average in strength, and most of them are just realm monks.

The house is quite large, and at this moment, the couple is very sad in the house.

Gu Na walked in with Song Kai.

When the couple saw Guna, they immediately fell to their knees, then wept and asked about the murderer.

Song Kai said: "Where was the body found?" ”

The husband pointed to the next room.

Next door is a children's bedroom, the bedroom is very large, it takes up half of the area, obviously the couple is very good to their child, and got him a lot of toys.

The bedroom has traces of being washed.

Song Kai frowned and asked, "This bedroom has been cleaned?"

The couple didn't know Song Kai's identity, but since Song Kai was with the goddess Guna, of course they didn't dare to slack off, and immediately replied: "It wasn't us who washed it, it should have been done by the murderer." The murderer took out my child's heart directly when he was still alive, and there should have been too much blood, so he washed the traces away with water. ”

Song Kai took a moment, he thought for a while, and said: "When you are alive, take the heart, then, the blood should be sprayed out, well, maybe there are really traces left, you close the window, and then block the window with a cloth." ”

The couple, do it immediately.

Song Kai let the couple out again and closed the door.

Guna stood aside and said speechlessly, "What are you going to do? Even if you want to find traces, you should open the window, now that the room is so dark, how do you find it?" Oh, with your nose?"

The female guard next to her muttered, "It must be a trick, and besides, he is not a dog demon, if it is a dog demon, this is normal." ”

"Look at what he wants to do. ”

The three of them looked at Song Kai with disdain.

Song Kai was looking for it very seriously, he blocked all the light, and then took out a flashlight from the storage ring.

If it weren't for being forced to have no choice, Song Kai really didn't want to show these high-tech means in front of Gu Na, after all, there were too many leaks of money, and it was easy to be robbed and killed.

Song opened the flashlight and first hit the fluorescent gear.

The flashlight immediately emitted a dark cyan glow.

Immediately, Song Kai immediately searched for it on the ground.

"What are you?" asked Guna curiously.

Song Kai said: "This is a special kind of stone, which can emit a special light, well, this kind of light looks very dim, but after it encounters some substances in the blood, it will emit special fluorescence, so I call him fluorescent lighting." ”

"Poof! That's a lot of nonsense. One of the female guards laughed disdainfully.

"That's it, it's not as reliable as a dog nose, you say you have a dog nose, we will all have some belief that this thing can be of any use. The other female guard also said disdainfully.

Song Kai frowned, he didn't explain much, he couldn't say that this is LSK fluorescence, there will be a reaction when it encounters hemoglobin, hemoglobin is insoluble in water, so there will be residues and so on.

There is no way to explain these things.

On earth, children can accept it, after all, they have watched police movies since childhood, and the police often hold ultraviolet lamps and highlighters and shine at the scene of the crime.

Here, it's hard to explain.

Song Kai took a photo, and then, he found a cloud of blood.

"Here it is. Song Kai said immediately.

Guna frowned and walked over, and suddenly, she snorted and said, "What is this?"

"This is the blood that remains from before. Song Kai said, "The other party doesn't know why, he didn't take the child away, and he didn't kill the child first, and then take the heart." Instead, choose to dig out the heart when you are alive, and at this time, blood will sputter out. Therefore, there must be blood stains on the other party's feet and body. ”

Gu Na looked at the flashlight in Song Kai's hand, "Why can your illuminating jade talisman shine out." ”

"Uh...... As I explained before, this kind of stone is specifically for blood residues. Song Kai was confused for a few words, and then quickly changed the lights.

It has become an ultraviolet lamp, which can extract fingerprints, as well as palm prints, in short, wherever the skin of the body has touched, as long as there is any trace of body fluid tissue remaining, it can be found.

However, the other party apparently did not sweat.

However, there was a lot of blood.

Song Kai continued to turn back into fluorescent lights, illuminating the ground, and then, when he arrived at the window, he immediately said: "Here, look, it's footprints"!

Guna hurriedly walked over, and sure enough, under the illumination of fluorescent lights, there was a footprint by the window, and the footprint was relatively small, similar to Guna's footprints.

"What's the matter with these footprints?" asked Gu Na with a frown, although her tone was very unfriendly, but obviously, she had been impressed by Song Kai's methods.

Song Kai said, "This must be the murderer's footprints, I said, this light of mine can shine the appearance of residual blood, the other party took the heart alive, there was blood on the foot, when he jumped out, although he cleaned up some of the bloodstains, but obviously, there was still a residue." You see, these are his footprints, and judging by his footprints, he ...... Hey, why are the footprints so small, is it a child?"

"Bang"!

Gu Na slapped Song Kai directly on the head, "Who told you that small feet are children! My feet are similar to this footprint, but am I a child?!"

"Yes, yes, yes. "Song Kai can only admit his mistake, my day, I actually inadvertently offended this big demon king! The key is that with a height of 1.4 meters, it seems that he is indeed a child.

Song Kai looked at the footprints, evaluated, and estimated that this murderer, his height, should also be very short.

Song Kai said, "Goddess Guna, I think, this is the clue, the murderer's footprints are so small, and, according to this pattern, the shoes he wears should be a special and more expensive shoes, after all, this pattern should be very rare." ”

"Wait. Guna frowned, and she turned to one of the female guards and said, "Come and see, do you know this pattern?"

The female guard walked over, looked at the pattern on the soles of her shoes under the fluorescent light, and immediately said, "Goddess Hui, this is the mark of the Mante family, the Mante family, in this city, is still very famous. ”

"Oh, then go to the Mante family, the shoes they produce should only be worn by their family. Song Kai said immediately.

Gu Na smmed for a moment, she looked at Song Kai, "I didn't expect that you really have some means, okay, if you can really find the murderer, I will let you and that demon beast go." ”

"Thank you. Song Kai breathed a sigh of relief, "Then, let's go to the Mante family now, but before we go, let's hide our identities first, so as not to be escaped by the real murderer." ”

"Yes. ”

Guna said to the two female guards, "You go back first, this gentleman and I, go to the vicinity of the Mante family and inquire about it, and see what is going on." ”

The two female guards immediately bowed down and agreed, and the two of them looked at Song Kai in surprise, but they didn't expect that Song Kai and the female vixen were really wronged.

Guna put on a very ordinary robe to cover her body, and then combed her braids, looking like a little girl.

Song Kai didn't need to hide it, no one knew him anyway.

"Let's go," Song Kai said, "let's pretend to be father and daughter now, and go to the shoemaker." ”

"Bang"!

Once again, Gu Na kicked Song Kai's ass, "What are you talking nonsense!

"Ahh Song Kai wiped the cold sweat from his forehead.

The two men walked towards the vicinity of the Mante family.

In this city, the Mante family is considered a big family, and all kinds of clothes and shoes in their house are made by the Mante family's logistics courtyard.

Song Kai opened the way with blood crystals, and he soon found out that all the shoes were made by the princess behind the Mante Mansion.

Wang Po's craftsmanship is very good, but there is a great demand in Mante Mansion, so Wang Po only does it for Mante Mansion, and the income is already very good.

"Hello Mrs. Wang. Song Kai immediately took out more than a hundred blood crystals and put them on Old Lady Wang's body.

When Wang Po saw so many blood crystals, she immediately smiled.

Song Kai took the opportunity to ask: "Granny Wang, think about it, a month ago, did any customer customize a pair of shoes that were quite small, oh, about the same size as my sister's feet." ”

As he spoke, Song Kai picked up Gu Na and showed her little feet......
