An old wallet containing several bank cards, a bulging envelope containing five thousand yuan in cash, an account book, remembering the money Du Laihua earns every time he travels to transport, etc. The last medical record book.

After picking up the case, Zhao Yongqi, who was standing upright, began to slowly open it, and Lu Han naturally came to the side.

The owner of the medical record is Du Laihua himself, who has been murdered, and there are only two pages of records, which is also the event this year.

Lu Han, who was standing next to him, said after reading it, "Genogenic congenital sterilization? No wonder Du Laihua still has no son or half of his daughter for so many years."

Zhao Yongqi, who nodded slightly, touched his chin and lowered his head to ponder, had the divine light in his eyes getting stronger and stronger. In the end, without saying anything, he took out the evidence bag he carried with him, put the medical record in it, and handed it to Wen Chenglong.

"Maybe this case is more complicated and more complicated than all of us imagined," Zhao Yongqi muttered softly, shook his head and began to search for other places.

After touching and touching each other for half an hour, even the medicine box was filled with powder in the room, no blood was found. Wen Chenglong made people move the tables, chairs, and even the bed, hoping to make a breakthrough in the foot of the bed where it is not easy to be seen. Unfortunately, it seems that Du Laihua was not dead here, and there were never any suspicious items in the room.

Holding his chin with one hand, the star eyes rotated around, and finally frozen on the bed.

The bedding on the bed was not folded, but was neatly laid on the bed like in a hotel. Just looking at the fabric, you can basically confirm that the bedding is very new and should have been replaced just recently.

Originally, it was just a bump in luck. The bedding in summer was very thin and there was only one layer on the bed. I lifted up the quilt first, and even the sheets were new, whether it was a pillow or a sheet, there was not even a single end, let alone other things.

Just as Zhao Yongqi sighed secretly and was about to put down the bedding, his eyes suddenly condensed and his eyes fell on the inner layer of the bedding.

He took the quilt to his eyes and carefully observed that the dark yellow stain that was only the size of a fingernail, which was close to the color of the quilt itself and was not easily noticed. After a moment, the man who was a little excited turned to Wen Chenglong and said, "Brother Long, give me scissors."

"Give it!" Without hesitation, Wen Chenglong took out the sharp medical scissors from his carry-on bag, and directly handed it to Zhao Yongqi.

After a while, Zhao Yongqi put the stained piece of cloth into the evidence bag and handed it to Dao, and said to him: "Go to the town public security bureau immediately. As long as we can figure out whether this is a body fluid, we will roughly find the murderer."

Seeing Zhao Yongqi's seriousness, Dao did not dare to neglect anything. Although he didn't understand what was so important, he nodded and turned around and rushed out of the room.

After thinking about it, Zhao Yongqi turned up all the bedding, sheets, etc. on the bed, waved to the medical box and said, "Brother Hua, come here to sprinkle some reaction powder."

"Okay." The medicine box holding the sprayer immediately walked to the side, and naturally the white crystal-shaped powder was sprinkled.

This movement naturally attracted everyone's attention, but unfortunately, there was still no change.

"It seems that I wasn't really killed here." Wen Chenglong sighed, as if he was ready to give up.

Zhao Yongqi, who was still looking down at the powder, reached out and knocked on the bed board and suddenly said, "Brother Long, everyone, let's say softly and put this bed up for me."

"Okay!" Even though he didn't understand why, Wen Chenglong immediately raised one side of the bed with the other men and gently raised the heavy bed.

As expected, just like Zhao Yongqi's imagination, the opposite side of the bed was thick square wood, with two gaps as thick as fingers in the middle.

Ask the medicine box to bring the sprayer, carefully spray the white powder on the square wooden strips at the edge of the gap little by little. After waiting for a few seconds, everyone's eyes widened instantly!

I saw that the originally white powder turned into light blue crystals on those square wooden strips in a very small area.

"That's right, Du Laihua was killed here! It was on this bed." Zhao Yongqi nodded, picked up his cell phone, and took the picture.

"Brother, what's going on? Why is there a bed on this bed, but there is no reaction on the ground?" Lu Han grabbed it and looked down at the place where there was also white powder under his feet, but there was no reaction.

"Put down this bed gently first, and try to return to its original state." Zhao Yongqi took the photo and began to direct everyone to put the bed down.

After a while of busy work, when trying not to make any noise, the bed was restored to its original state, and then everyone put the bedding and other objects back on again, Cheng He said: "Xiao Qi, you just like to suck people's appetite. Should you say it now?"

"It's very simple. The reason why Zhang Yulian had to replace many daily necessities and clean the room was to use low-concentration hydrochloric acid to clean all items, including the ground. It is normal to have hydrochloric acid in rural areas, and it is often used to wipe the toilet. The chemical composition of hydrochloric acid can greatly decompose various heme in the blood, etc. I just found out that the bed board of this bed looks very new, not like it has been used for a long time. Although it is normal to replace the bed board, it is so coincidental that it has been replaced in the past few days.

It's not reasonable. So I tried to turn the bed board up. Even if Zhang Yulian was careful, she could not use hydrochloric acid to clean the wooden strips. This is an easy place to ignore." Zhao Yongqi pointed to the back of his head and said, "In addition, Du Laihua's back of his head is very small, so there will be no blood gushing out. Combined with the two situations, I think there may be traces of blood in the back of the bed board, so I tried it, but I didn't expect to hit the big fortune. Now, we are almost certain that Zhang Yulian must be related to the murder case!"

After listening in a daze, Deng Chao cursed softly: "Damn, it's the most toxic woman's heart. This is pure murder of his own husband!"

"Brother Xiao Qi, should we arrest Zhang Yulian immediately?" Wen Chenglong asked after thinking about it.

"No, we have no key evidence!" Zhao Yongqi said with certainty: "Even if we can prove that the big and small footprints on the side of the little girl's wooden hut were from Zhang Yulian, but because she had been there that day, she could not make any evidence at all. As for the blood here, even if it could be proved that it was Du Laihua's blood, it could not prove that it was the blood shed when he died. As a wife, Zhang Yulian could say that this was the one that broke his hands and feet when he was drunk. We couldn't refute it. Now, we need a key evidence that can convict her!"
