"He family, is it the he family?" Ye Xin is very familiar with these materials of China. Coupled with the background of Ye family, it won't be strange for her to know these.

"Well, I wonder why he became the instructor this time." Just after Zhou Rui said that, Zhang Jing came out of the library, nodded and said hello, and left the library directly.

"Come on." Zhang Jing was followed by Zhou Rui, and Ye Xin smiled.

"Ye Xin, what do you think of this assessment?" Zheng Kai's observation is always careful, and Ye Xin is very intelligent. After Zhou Rui enters the assessment classroom, Zheng Kai asks.

"If you come, you will be at ease."

Ye Xin's implication is that no matter what the purpose of the assessment is, it's best not to have a relationship, but there is a guess in both their hearts. This assessment may be related to Lin Shengyi's departure, but Zheng Kai's heart is doubt, while Ye's heart is affirmation.

"Brilliant." Zheng Kai thumbed up and said that Zheng Kai's actions made Meng Qing turn a blind eye not far away. These days, Ye Xin also roughly knows the origin of Meng Qing. Meng Qing comes from a police family, but he aims to become a forensic medicine, and his goal is very firm. Ye Xin doesn't hate Meng Qing's pride, because Meng Qing's family does have the capital of pride.

After Zhou Rui came out, Ye Xin went in.

"Mr. Ye, please sit down." Ye Xin hasn't spoken yet, he Zetian said directly.

"Yes, instructor he."

"The first pass tests Ye's observation and memory."

He Zetian handed Ye Xin a photo, which was about 15 * 20. Although it was small, the pixels were very high. A man in a white coat and about 40 years old lay in a pool of blood. About ten seconds later, he Zetian took back the photo.

"According to the photo analysis, the time to take the photo should be at night. It should be a long-range sniper from the blood flow. Not only that, it also uses special bullets to drive from the photo facilities, like a laboratory, but also has something to do with the army." Ye Xin replied confidently.

"How do you make sure it's night?"

"The light and shadow effect plus the man's falling position and fatal injury. I think an ordinary policeman can see the fatal injury. It should be long-range shooting. Long-range sniping can't be carried out without seeing. In addition, the light is several color scales brighter than the day, and the time can be determined to be at night."

According to Ye Xin's analysis, he Zetian showed a very surprised expression in his heart. He was ordered by the old man and had been secretly checking Ye Xin. He wanted Ye Xin to meet the old man. Unexpectedly, Ye Xin came to participate in military training.

"How can you see that it has something to do with the army?" He Zetian asked with a little interest.

"First, this photo scene is not artificial. Second, there is an insect at the foot of the body and the pollen on the trouser leg of the body. It can be determined that the murder should happen soon. In addition, the experimental equipment is specially provided and can only be used by research institutes recognized by the state. The third and most important point is that you have to ask in person."

"The third point is just your speculation, there is no actual evidence." He Zetian looked at Ye Xin and thought that she was really smart. No wonder she regained her position in less than a month after abandoning the Ye family.

"Excluding all the impossibilities, the rest is the correct answer, and the speculation is based on the evidence."

"Yes, from what you can see, can you guess who did it?"

This question is hezetian's test. In fact, from the scene last night, he and he can roughly determine that it was done by the sniper, but at least two thousand meters away from the best sniper location. Moreover, he searched within two thousand meters and didn't leave any clues at all, so it is called the biggest question in his heart.

"I never have to guess. If I want to be a forensic doctor, I just want to see the truth, not the police. Who is the murderer? It's the police's business. Instructor he is still satisfied with this answer."

After a few questions, Ye Xin was sure that this question would not be assessed, but tested.

"Satisfied, after the assessment, call the next one in." He Zetian was silent for a few seconds. Ye Xin's last words almost made him unable to react, but the only thing he could be sure was that Ye Xin was very rational and not a person troubled by ordinary people's view of right and wrong.
