C690 Find Clues

"You mean the killer and the victim are acquaintances, we've considered that before, but there's no target. Professor Liu is a nice guy, he rarely makes enemies, so there's no way to determine the scope of the fight. There's also no way to confirm it." Xia Xue said.2

"In that case, let's restore the crime scene." Yang Tao stood at the door and said, "Assuming I'm the killer, I came to look for Professor Liu, knocked on the door, came to the living room, and said something to Professor Liu. Professor Liu turned around, then I stabbed Professor Liu, what would happen?"

"Of course, Professor Liu was killed." Xia Xue said.

No, it's blood, there's a big artery on the back, so there's definitely going to be a lot of blood coming out, and then it will definitely splash on my body. My hands and clothes are covered in blood, and the blood on my clothes can take my clothes off, but what do I do with the blood on my hands?

He looked down along the pipe and connected to the water pipe in the corridor, but didn't find anything. He ran to the bathroom and did the same thing, but found something at the corner of the sewer. A bloody fingernail was tied up by the hair in the sewer, so it wasn't washed away.

"I found the clue." Yang Tao was very happy and Xia Xue was a bit confused. There was a clue just by looking at it. Yang Tao didn't care about anything else, he just laid on the ground, opened the lid under the corner and pulled out his hair.

"Hey, what are you doing? Do you feel nauseous? Are you going to use your hands?" Xia Xue asked.

"This is a clue, what's so disgusting about it?" Yang Tao didn't care about it, and directly started to pick at his hair.

"You mean these hair are clues?" Xia Xue asked while covering her nose.

"Of course not. These hair should be Professor Liu's. He probably fell in while washing up." Yang Tao said.

"What can that lead to?" Xia Xue said with a frown.

At this moment, Yang Tao took out the nail with a little bit of blood on it and said, "The real clue is this."

"What is this?"

"This is a bloody nail. Judging by its size, it should be the nail of a man's thumb. Because it's too big, it got stuck. It must have been cut in a hurry, so it's very irregular. " Yang Tao said.

"Could this be Professor Liu's."

"I don't think so. From his fingernails, he should be a young man. It's hard to say exactly how old he is, but he's definitely not as old as Professor Liu." Yang Tao said.

"You can even see that?" Xia Xue was slightly surprised.

"Of course, if you don't look at what I'm doing, I know a lot about the structure of the human body." Yang Tao said, "You'll know when you take it back for analysis."

Xia Xue put her nails into the bag. Yang Tao washed his hands and said, "How is it? Did I find some clues?"

"Humph, I'm not sure if this can become a clue. I have to go back and test it out." How could Xia Xue admit her loss so easily? However, she had witnessed the process of finding the clues with her own eyes.

"Tsk tsk, you don't have to worship me. You just believe in machines too much. Some things can't be compared with machines, such as human eyes." Yang Tao said.

Xia Xue was about to retort, when she suddenly heard someone shout from the door, "Who are you? Why are you here?"

Yang Tao and Xia Xue turned their heads and saw a woman standing at the door. She seemed to be in her twenties, had long hair, and was very pretty. She was not a bit less than Soong Jia, and her figure was very good.
