At the beginning, he crossed over to become the cannon fodder villain's father

Director Ma also agreed with Zhao Chengfeng's statement, and immediately arranged for him to join the investigation team of this case, and his identity also belonged to foreign aid.

But this is not important anymore, all Zhao Chengfeng needs is that he can participate in this case.

Afterwards, Zhao Chengfeng followed the investigation team to the scene of the crime to check the situation.

"Mr. Zhao, I really didn't expect you to come here in person this time. In this case, we are all full of confidence now!"

"Yes, Mr. Zhao, if you find a clue later, don't forget to share your experience with us. This will definitely be of great help to us in handling cases in the future!"

Almost everyone in the investigation team knew Zhao Chengfeng, so they all knew Zhao Chengfeng's strength very well.

Zhao Chengfeng smiled and nodded.

"Don't worry, it's all fine. As long as I find a clue, I will definitely talk to you about it."

But Zhao Chengfeng knew that this time the matter would definitely not be that simple, otherwise, the system would not have issued him a task.

Coming to the scene, Zhao Chengfeng began to check the situation on the field.

He found that this is a rental house, the interior decoration is very simple, it looks like an ordinary person with no background.

"Mr. Zhao, the deceased this time was a migrant worker. He has been working here for two years. He has no social background and is alone!"

The police next to him saw that Zhao Chengfeng was investigating, and immediately came up to introduce him.

Zhao Chengfeng nodded.

Then he began to check other situations in the room.

The time of death of the deceased has not passed for a long time, so the whole room is filled with a strong fragrance.

This is why the police judged that he was poisoned by Xiang Fang.

The scent here has not completely dissipated, Zhao Chengfeng also began to smell it carefully.

Now, he also discovered the problem here.

After all, Zhao Chengfeng exchanged the mastery of medicinal materials from the system at that time, so as for the medicinal materials in these incense prescriptions, one only needs to smell them to know.

He also found something wrong here.

Because according to the medicinal materials represented by this fragrance, they are just some simple spices, and they have no ability to kill people.

"Is there any quality inspection report for these incense ash? Show it to me!" Zhao Chengfeng asked a policeman beside him.

"Yes, yes, Mr. Zhao, we analyzed all the ingredients of this incense ash this morning, and I will show it to you!"

The policeman immediately went to get a copy of Xiangfang's inspection report and handed it to Zhao Chengfeng.

"Mr. Zhao, this is it, take a look!"

Zhao Chengfeng nodded.

He carefully checked the ingredients of the incense prescription displayed on the report.

Now he can be sure, according to the fragrance in this room and the ingredient report of the incense, it is definitely not the incense that caused the death of the deceased.

He also informed the police at the scene of the discovery.

The police are confused.

"Mr. Zhao, why is this? We didn't find any traces of fighting at the scene, nor did we find other people's fingerprints, and we didn't find any signs of suicide from the deceased. The only problem is this incense. !"

The words of the police reminded Zhao Chengfeng that he decided to test the ingredients of this incense himself. After all, it is very likely that someone from the laboratory of the police station missed a very secret and deadly ingredient in it.

So he then brought some samples of incense ash from the scene to the laboratory of the police station.

When the people in the laboratory saw Zhao Chengfeng coming, they couldn't help being a little puzzled. Although they had all heard of Zhao Chengfeng, they had only heard about Zhao Chengfeng's strength, but they had never seen it with their own eyes.

So they all had question marks about Zhao Chengfeng, and they didn't think he was as powerful as the legend said.

"Hehe, Mr. Zhao, what are you doing here? We have already tested the incense ash this time, and the test report has already been printed out. Do you want to do another test?"

"You obviously don't believe in our ability, and we definitely won't make any more moves!"

These people were very dissatisfied with Zhao Chengfeng bringing the incense ash over, and felt that Zhao Chengfeng simply didn't believe in their abilities.

But Zhao Chengfeng just smiled lightly.

"Hehe, it's okay, you don't need to do it, I will do the inspection myself!"

Zhao Chengfeng then walked directly into the examination room, ready to start the examination.

This made everyone in the laboratory feel very ridiculous.

After all, in the laboratory, their instruments are very advanced and precise, so they think it is impossible for Zhao Chengfeng to use them.

As a result, they all started to laugh at Zhao Chengfeng.

"Hehe, Mr. Zhao, do you know how to use these things? If not, don't operate carelessly. These things are not cheap, and they are very difficult to buy. You must be careful! "

In their opinion, it is definitely impossible for Zhao Chengfeng to use these devices, after all, he has not had professional training.

So, they were all watching from the sidelines, waiting to see Zhao Chengfeng's jokes.

But Zhao Chengfeng didn't seem to want to give them this chance to see a joke, and even used his own strength to slap these people in the face.

Zhao Chengfeng came to an instrument, put a sample of incense ash on it, and then skillfully manipulated the instrument to analyze the ingredients.

After that, he used the rest of the instruments very proficiently, not like a layman at all, but more like a skilled worker who often uses them.

This surprised those few people. The mocking smiles on their faces just now disappeared, and all they got were surprised expressions.

In fact, what they didn't know was that Zhao Chengfeng was proficient in the instruments given by the system, so he knew all kinds of instruments at a glance.

In this way, operating these instruments is even more proficient than the inspectors who deal with these instruments every day.

But after a while, Zhao Chengfeng couldn't help squinting his eyes, because among the ingredients of these incense ashes, he still didn't find anything that could kill people.

Could it be that the fourth aunt of the deceased had another reason?

As a result, the people in the detection department saw that Zhao Chengfeng didn't seem to find anything, and once again put on a mocking smile on their faces.

"Mr. Zhao, you see, we all said that we are professionals, so you haven't found anything!"
