Yan Mo and Xiao Dong walked out of the room and came to the living room of Wen Liang's house, at this time Xiao Kong was chatting with Wen's mother, "Auntie, don't worry, we can definitely solve Wen Liang's matter, you must live well, you think, Wen Liang chose the path of being a police officer without hesitation in order to make you proud of him, I think he and your daughter-in-law will pay attention to you every day in the spirit of heaven and bless you!" ”

The thick sadness on Mother Wen's face has never dissipated, Xiaokong's comfort and enlightenment have not changed much, yes, the fact that the white-haired man sent the black-haired man made him unable to wake up from this nightmare, only the murderer can find the haze in her heart to dissipate, or perhaps, time is the best way to smooth out the scars.

Seeing Yan Mo and Xiao Dong coming out of the room, Xiao Kong handed over an inquiring look, Yan Mo bit his lower lip lightly, and walked in front of Wen Mu without saying anything, "Xiao Dong, have you found that book?" Xiao Dong scratched his head, "Auntie is like this, we didn't find the book in Wen Liang's room, but strangely found that the content of the documents in the computer was deleted, and only a wallpaper remained, has Ling Xuehua used the computer recently?" ”

Wen's mother said without thinking: "After Wen Liang went, Xuehua's girl slept in Wen Liang's room every day, she said that only by staying in Wen Liang's house would she not feel Wen Liang's departure, this girl is really, I persuaded her several times to find a time to slow down her spirits, so as not to let him delay her own beauty for Wen Liang, but her reply to me was that she would take care of me until I was old in this life, and she didn't want to think about the rest now." ”

Mother Wen closed her eyes, thought for a moment, and then said: "I remember the day before yesterday, I went to the room to find her, and she was browsing the photos taken when he and Wen Liang went to the scenic spot a few days ago. "Then you should know when they're going to travel!" Yan Mo felt that there would be a conflict between the time and the time on the picture this time, so he asked Wenmu anxiously.

"Around May. It seems like it's Labor Day! After hearing this, Yan Mo's mind quickly turned, "The picture has obviously been changed in time, and the number of floor tiles happens to be 9 lines, so is the secret hidden in the tiles, or on the tiles?" ”

"Auntie, there is one more thing, can I tell you about it?" Yan Mo knew that Mother Wen might be the last person to know the secret of tiles, and he couldn't destroy the tiles by force, so he had to learn about the situation from Mother Wen. "Oh, is there anything else I need help with?"

"When Wen Liang was repairing the room and laying the floor by himself, did anyone ever help him?" "Probably, I was going to work that day, and Wen Liang didn't have breakfast in the morning, when I came back in the afternoon, I saw two pairs of chopsticks on the dining table, and there was unfinished soy milk on the kitchen door. I asked him why, and he said he had accidentally knocked over the bag of flour, but I remembered that the bag of flour was unopened, and I didn't think it was a big deal, so I didn't ask the reason again! ”

"Flour, do you remember if the flour was spilled in his room?" Yan Mo asked Wen's mother urgently, "I don't remember, there was too much cement and dust in his room that day, and I couldn't identify it if it was mixed together, but when the floor tiles could be stepped on a few days later, when I swept the soil on the tiles, I found a lot of sand grains similar to salt blocks." "Salt?"

"By the way, starch turns blue when it encounters iodine! Did he try to observe the color reaction with starch and iodized salt in contact? Yan Mo's originally incomprehensible heart began to gradually loosen, and the path of cracking it step by step flashed in his mind, Xiaokong went to our office to bring iodine wine, okay?" "Well, no problem, I can buy it at a nearby clinic!" When Xiaokong got up and was about to leave, Wen's mother drank Xiaokong.

"No need to go, I have iodine at home! That's what Wen Liang bought it, Wen Liang's child will be tired from running around outside every day, and occasionally he will come back to wipe some iodine wine to disinfect it, which is in his computer desk! I remember it's inside the drawer on the left, you go get it! "Yes, Auntie!"

Xiaokong entered the room to get iodine wine, Xiao Dong went to the kitchen and brought a small bowl of flour with a small bowl, Yan Mo took the small bowl from Xiao Dong's hand, took a water cup on the table, and poured a small amount of flour into it, at this time Xiaokong also took out the iodine wine, walked to the table and handed it to Yan Mo, Yan Mo opened the bottle and dripped a few drops of iodine wine into the water cup, when the iodine wine came into contact with the flour, the flour underwent a complexation reaction, and the flour in contact with the iodine wine showed a dark blue color.

"The iodine in iodine wine hasn't expired yet, go to the room and take a look!"

The four of them came to the room, Xiao Dong helped Wen's mother to sit on Wen Liang's bed, Yan Mo squatted on a tile indicated by the code, took out a pack of toilet paper from the back pocket of his pants, took out a sheet from it, wiped the surface of the tile clean, the tile is square, and some decorative patterns on the tile are twisted irregularly, Yan Mo poured a small part of the flour in the bowl on the tile, evenly smeared it on the surface of the tile and compacted it with his hand, and then wiped the starch on the unmarked tile with a paper towel. After that, the iodine wine is dropped on the top and bottom of the tile, the left and right sides and the middle five corners, and slowly the same method is dripped evenly on the tile, and the change of the color of the tile is slowly observed!

When the iodine wine dripped in the middle and upper position of the tile, the iodine wine that originally dripped on the tile in the shape of water droplets slowly penetrated, and then showed a slender dark blue line near the dripping tile, Yan Mo cautiously dripped iodine wine along the line, and along the direction of the line, a quarter of the area of the 160 cubic centimeter tile appeared lines, Yan Mo and Xiao Kong and Xiao Dong hurriedly took out their mobile phones to take pictures of the patterns that appeared, and Wen Mu saw this scene, and her rickety body stood up tremblingly, Sora hurriedly stepped forward to hold her and prevent her from falling.

After making a major discovery, Wen Mu's hands trembled even more, "Quick, is there anything else?" Find out the rest! After Xiao Kong placed Wen Mu on the bed, he continued to help Yan Mo spread flour on the marked tiles, while Xiao Dong wiped the flour on the tiles on the side, Yan Mo carefully and seriously dripping iodine wine, the three of them worked together, and the efficiency was very fast!

Not long after, the three of them also photographed the patterns hidden under the bed and under the table. The four of them returned to the living room, no longer busy, the room was very quiet, Wen Mu looked at the sweaty three, and the expressions on the faces of the three were not excited because of these patterns, but more calm, deep, Yan Mo's deep eyes flashed with a cold light!

|“ Auntie, do any of Wen Liang's friends specialize in carving? The pattern on the tile is obviously carved by Wen Liang asked the tile carver master, and the skill is so superb that we almost didn't find it! "Xiao Liang's friends, I just know a few of the people he once brought, and I haven't heard him mention it to other friends!"

"I don't think it's easy to carve a tool! Let us not feel the existence of scratches when we touch them with our fingers, let alone a person with extremely sensitive fingers like you, or is this master of carving tiles exquisite!"
