What Li Qing prepared was simple: a scalpel, a magnifying glass, a cotton swab and a plastic test tube.

These are very inconspicuous things in Li Qing's opinion, even if they are discovered, they will not cause major problems, and besides, He Cuo is easy to use, but, in this world, these things will undoubtedly make He Cuo feel rare and shocked-

The scalpel had a silvery sheen, and its sophistication was completely incomparable to that of the tools he was used to.

As for the magnifying glass, he had never seen it before, but as soon as he held it in his hand, he could see the beauty in it.

He Cuo couldn't imagine where Princess Yi got these treasures.

However, cotton swabs and plastic test tubes, he didn't understand.

Li Qing's note also emphasized the use of these two things—she wanted to extract the DNA of the Iron Cow—of course, she would not explain the complexity of extracting DNA.

To extract the DNA of an iron cow, it is most appropriate to inspect the site. Where Tie Niu lived, there would be many traces, especially the hair that fell out of his body, and so on. However, the inquest of the body is a difficult opportunity, and it is better to be cautious about such a request at the scene.

If the iron bull sex/invades Yingniang, it will be convenient, and the cotton swab and plastic test tube given by Li Qing are used for this.

After reading the note left by Li Qing, He Cuo quickly pinched the note in the palm of his hand.

Ye Lan, who was guarding him at the door, saw that he stood in front of the toolbox for a while without moving, and felt a little strange, and couldn't help asking, "What's wrong, why don't you do it yet?" ”

He Cuo turned his back to the door, took a deep breath, and said, "I'm sorry, I just ...... I just need to calm my emotions. Right away, I'll start doing it right away. ”

He wiped his eyes as he spoke, and swallowed the note left by Li Qingliu into his stomach.

Ye Lan didn't think that there would be a cat in the toolbox that their princess had personally inspected, he didn't make any mistakes, he still stood at the door with his back to the outside and inward, watching him take out the tools from the toolbox and start the autopsy.

The work did not take long.

Yingniang had countless criss-crossing scars on her body, the cause of death was excessive blood loss, her heart was dug up after death, and she was sexually assaulted before her death.

In order to avoid being seen by Ye Lan, who was staring at him, he did not use the scalpel provided by Li Qing, only used a cotton swab and a plastic test tube, and extracted the specimen according to Li Qing's requirements, and experienced the wonders of a magnifying glass.

When he finished all his work and turned around, he saw Ye Lan staring at him thoughtfully, and his heart couldn't help but jump hard.

He Cuo quickly calmed himself down and asked calmly, "Does the night guard have any questions?" ”

Ye Lan asked: "Wangfu Chuntao case, I heard that you invited Wen Po, but I think you seem to have done everything you should have done just now." ”

It turned out to be this.

He Cuo said expressionlessly: "Even if the palace Chuntao is the last Yahuan, it is also the Yahuan of the palace, and this woman is just a prostitute with thousands of people riding 10,000 pillows in the Drunken Flower Building, can the two compare?" ”

Ye Lan said in his heart: The performance of a person who has been wearing a mask for a long time after removing the mask will really surprise people.

On this day, they went back and forth from the Yushitai to the government office, but the iron bull did not appear.

Early the next morning, Hua Xiao asked the government to issue a notice, saying that the real murderers of Xiang Cheng and his wife had been arrested.

Qi Yuren stood at the door of the mansion and passionately declared that the Xiangfu case had been solved, and the "Hui Ghost" was just a way for the murderer to cover up people's eyes, and the murderer had now been brought to justice, so that the people did not need to panic.
