Why do we drive out? Because the short-distance flight will consume very little energy unless the ghost reaches the level of Wei Feihong and his ancestors. If we fly over, it will be fine, but we will be so tired that we cannot survey the scene.

As for the situation across cities and provinces, the ancestors also had to take transportation, but they didn’t have to buy tickets. Having high-level good ghosts on the plane will play a certain role in protecting the safety of the plane and humans on board.

Ghosts are not stupid either. With modern technology, they can save time and effort for themselves. Isn’t it delicious?

Soon, the car arrived at the streets near the Dadu villa area of ​​Anping.

After parked the car, Tang Yuyan used her mana to detect it, and confirmed that there was no one or camera around, so she invisible herself again.

Two souls and one ghost floated out of the car and walked towards the villa area.

Following the community floor plan drawn by Luo Chao, we found the villa where poison arrows were shot.

At this time, the villa gate had been stamped with seals, with the words Anping Municipal Public Security Bureau written on it.

After entering the house through the wall, we came to the window where Luo Chao described shooting poisonous arrows.

I saw that the glass of this window had been broken and the glass residue fell on the windowsill and the ground.

I briefly observed that this is one of the kitchens in the villa, which is very spacious.

Generally, from the kitchen photos, you can see whether the whole house is a big house. You can see from the kitchen operating counter.

For example, the operating table in this kitchen is a four-sided type, that is, a rectangular piece is built in the center of the kitchen, with a vegetable washing area, a vegetable cutting area, etc. Housewives (husbands) can chat with relatives and friends face to face while processing the ingredients.

At this time, I said to Tang Yuyan: "You detect the window, I detect the ground."

Tang Yuyan nodded and said, "Okay."

Next, I began to activate my mana to perform a microscopic scan of the floor of this kitchen.

There is indeed very thick dust on the ground, and there are some fresh footprints with regular routes on it. They should have been left by the public security personnel during the investigation. There are about three people. Apart from this, no footprints of the fourth person were found.

Then I turned my attention to the dust, scanned the ground, and found a very interesting situation.

That is, there is no footprint under the dust on the entire kitchen floor, only the traces of the mop being mopped.

Then I scanned the operating table, which was also a thick layer of dust. Then I scanned the dust below, just like the ground, and was wiped by the same mop for a round.

Why can I tell that the same mop was rubbed for a round just like the ground?

Dr. Li Changyu, a famous American Chinese detective, proposed a theory of investigation, that is, when any object comes into contact with another object, these two objects will definitely leave their own traces on the other party.

This is called material exchange. For example, if two people shake hands, they will definitely get sweat, dirt and skin debris in the other party's palms, and even... Forget it, I won't say it anymore, so as not to be excited, no, disgusting.

This is why I was very eager to find a bathroom after shaking hands with anyone, and I needed a bathroom with hand sanitizer.

I have shaken hands with very famous big stars and provincial and ministerial leaders, but I still dislike it and must wash my hands as soon as possible!

Dr. Li Changyu (although I admire him very much, I have to wash my hands even after shaking hands with him!) There are many cases that I have solved using this theory. One of the most impressive ones is that a police officer was hit by a car on the road in the middle of the night and died, and then the car escaped.

There was no camera at the crime scene, and the police officer did not turn on the law enforcement recorder.

By checking the ruts, we can know that it is a common truck on American highways.

So the police searched all the way, and two of them found a suspicious truck at a gas station more than 100 kilometers away.

It was a flat-head truck with signs of impact on the right side of the front of the truck.

So the police asked the driver, buddy, what did you hit?

The driver said in Northeastern English that I hit a wild donkey a few days ago.

The policeman turned around and asked another policeman, do I remember if there are wild donkeys here?

Another policeman said, yes, I'm sure.

Yes, no, yes, no, yes.

Seeing that the two policemen were about to start arguing, the driver was talking. You are quarreling, and you are still not trying the suspect? If you don’t try, I will continue to pull the wood.

The policeman was right to think about it, so he bent over and studied the impact dent carefully. The more he thought about it, the less he felt, he became less and less excited. So he waved his hand, and took it away!

He took people and cars back to the police station, and the police leader turned from initial excitement to sorrow.

The car was clean and it seemed that it had just left the bathhouse. There was indeed a collision mark on the front of the car, but it was obviously not the shape of a human or the shape of a wild donkey.

So the police leader asked the two policemen who caught the truck driver, why, in your hometown, the car was accidentally bumped into the car and how many years would it take to continue driving on the road?

The two policemen were eager to make contributions and said, "Brother, don't we rather kill 10,000 by mistake and not miss 3,000. Leave it to me, beat me, see if he will not do anything!"

The police leader rolled his eyes and said, I'll go and chat with him!

As a result, the driver was not afraid of the police leader, saying that I had the right to remain silent, I wanted to meet my lawyer, and I wanted to drink coffee and eat fried chicken.

The police leader shook his head and thought of his leader, that is Dr. Li Changyu.

Dr. Li Changyu was heartbroken and rushed over quickly when his subordinates were killed.

Standing in front of the truck, holding a magnifying glass and looking again and again, Dr. Li Changyu pointed to a position on the front of the car and said, "Do you look at this subtle scratch, like a corner of the police badge?"

Everyone gathered around and saw it and said it was really similar.

Unlike the policeman who said there were no wild donkeys in the area said.

Seeing that everyone turned to stare at him, the humanoid etc lowered his head against his will and said against his will, like.

Dr. Li Changyu waved his hand and said, "Take the substance on this scratch to test it!"

The result was as Dr. Li Changyu thought. Under the microscope, the fine metal debris of the police badge were trapped in the car paint, so it was not washed away.

So the police stalked towards the interrogation room, opened the door, looked at the driver who was drinking coffee and eating fried chicken with a comfortable look and said, "Guess why we are as happy as you?"

The above is the specific meaning of material exchange.

At this time, Tang Yuyan walked to me and said, "It's a human being."

I also said, "Not a ghost!"

Wei Jin said at this time: "Then what else do you care about? Let's go."

I shook my head and said, "But I still want to help Luo Chao."

Tang Yuyan thought for a while and said, "Marry a chicken and follow the chicken and follow the dog, I support you and help Luo Chao!"
