Su Xianrong didn't understand what Song Ruilong was doing when she asked her to press it on the white paper, but she believed that Song Ruilong would not harm her.

Su Xianrong looked at Song Ruilong strangely and pressed it on the white paper, and said, "Brother Song, what are you going to do?" Make it so mysterious. ”

Song Ruilong slowly picked up the piece of paper, and after letting Wei Bixiao, Liu Tianxiong and others read it, he said: "Everyone has seen it, this is a blank paper, if you don't know who touched this blank paper just now, then I have a way." Let's come and see. ”

Wei Bixiao and the others gathered in front of Song Ruilong to see what he was going to do.

Song Ruilong sprinkled toner on the white paper, and then he gently shook the white paper, causing the toner on the white paper to slowly fall on the table.

When Song Ruilong completely shook off the toner on the white paper, everyone was stunned. Liu Tianxiong exclaimed: "Crayfish, what kind of trick are you doing?" How can you make Miss Sue's fingerprints appear on a blank piece of paper? ”

Song Ruilong said: "You can now let Rong Rong press the ink on his middle finger, and then press it on the white paper."

Su Xianrong pressed it on the blank paper, and after taking his hand away, Liu Tianxiong said in surprise: "Miss Su's handprints are exactly the same twice. If we haven't seen Miss Su touch this piece of paper, then we can conclude that Miss Su has touched this piece of paper based on Miss Su's handprint. It's amazing. With this method, we can conclude who the murderer is. ”

Wei Bixiao also said excitedly: "That's right, in the past, we only judged the murderer based on the fingerprints with blood marks, so that as long as the murderer touched something in the house, we could extract his fingerprints."

Tie Chong's eyes stared at the white cloth glue in Song Ruilong's hand and said, "My lord, what does this thing do?"

Song Ruilong smiled and said: "This white cloth glue is glued to fingerprints, and it is impossible for the murderer to leave fingerprints on the paper every time." If it is on a table or a cabinet, it is impossible for us to carry the table and cabinet to the county office, so this white cloth glue is used to glue fingerprints. ”

After Song Ruilong finished speaking, he also demonstrated once, and he asked Tie Chong to press it on the table. Then sprinkle it with toner, blow it away with your mouth and blow away the toner that can't be glued, and finally, a very clear fingerprint appears on the table.

As soon as Song Ruilong glued it with white cloth glue, the fingerprint went to the white cloth glue, and it was very clear. Liu Tianxiong looked at Song Ruilong in surprise and said, "Crayfish, your method is really magical, can you tell me how you did it?"

Song Ruilong said: "It's actually very simple. We know that there will be some sweat on our fingers. When the sweat comes into contact with something else, it stays in that place, and it forms an invisible fingerprint. I added a very adhesive powder to these toners, and the function of the toner is to make the toner adhere to the fingerprint, and the function of the toner is to display the fingerprint. It's actually quite simple. ”

After Song Ruilong told them about the method of taking fingerprints, Liu Tianxiong and the others were very excited.

"My lord, there are two people outside the door who have come to report the crime."

Song Ruilong said when he saw Wang Yu in front of the county office.

When Song Ruilong heard that there was a case, his nerves immediately collapsed. looked at Wang Yu and said, "What is the case?"

Wang Yu said: "It's a talent and an old man. The two said that there was an old man named Wang Jinhua, who had not been seen for seven days and might have disappeared. ”

Wei Bixi rolled his eyes and said: "Since they didn't see the corpse, it doesn't mean that Wang Jinhua has been killed, this old man may be confused, when he comes back from a long away." I forgot the way, just leave this matter to Wang Yu to check if there is any lost old man. ”

Wang Yu didn't know how to choose, he looked at Song Ruilong and asked, "My lord, ...... you see?"

Song Ruilong said very seriously: "First bring the reporter to the reception hall." Xianrong and I went over to find out the situation. ”

Wang Yu nodded and went out.

When Song Ruilong and Su Xianrong walked to the reception hall, the two informants were already waiting in the hall.

There was a young son, with a square scarf wrapped around his head and a book of "Analects" in his hand, got up, hugged his fist at Song Ruilong, and said, "Xiaosheng Xiang Sihang has seen Lord Song."

Another old man knelt down for Song Ruilong and said very respectfully: "Xiaomin Liu Qing has seen adults."

Song Ruilong helped Liu Qing up, let him sit on the chair, and let Xiang Sihang sit down, he slowly sat down on the chair, and said: "This county heard that the two of you are here to report the case, what is going on, you tell the county carefully."

Xiang Sihang rolled up the book in his hand and said generously: "My lord, this is the situation. This morning, when Xiaosheng was eating steamed buns at Qingshou Bun Shop, he heard Boss Liu, who is also the old man Liu Qingshui, say that Aunt Wang Jinhua, who lives in Room 18 of Chaoyang Lane, Anding Road, has not eaten steamed buns and porridge in his steamed bun shop for seven days. Boss Liu felt that this incident was a bit abnormal, so he came to the county office to report the case. Xiaosheng also felt that Aunt Wang had no relatives and no reason, and it was impossible to go out to relatives, so Xiaosheng and Boss Liu decided to come to the county government to report the case as soon as they put it together. ”

Song Ruilong only listened to Xiang Sihang's words and was not sure what happened to Wang Jinhua, but he felt that there was no big or small civil matter, and he should go there in person.

Song Ruilong said: "If you say so, the county can't be sure what happened to the old man Wang Jinhua, but the county can go to Wang Jinhua's house with you to have a look."

Song Ruilong changed into a ranger's clothes and followed Liu Qingshu and Xiang Sihang along Anding Road with Su Xianrong, turned into Chaoyang Lane, and soon came to the door of Room 18.

The gate of Wang Jinhua's house is a vermilion lacquer gate, and there is a pair of stone lions in front of the gate.

Although the pair of stone lions is not big, but it is also unaffordable for ordinary people, from the gate and the stone lions, Song Ruilong concluded that Wang Jinhua's family must be very rich.

Looking at the lock on the gate, the lock is a very heavy copper lock, and this kind of lock is not something that ordinary people can use.

Song Ruilong pulled the copper lock with his hand, looked at the keyhole of the copper lock again, and said: "The lock on the door is intact, which means that Wang Jinhua is not in the house, and she may never come back after she went out."

Su Xianrong said: "Maybe after Aunt Wang was killed at home, the murderer locked the door with the key, which is also possible."

Xiang Sihang thought for a while and said: "If Aunt Wang goes out, she should at least say hello to her neighbors, but the current situation is that her left and right neighbors have not received the news that Aunt Wang has gone out, which shows that Aunt Wang is likely to be more than lucky."
