The methods of the four departments are becoming more and more mature. Wang Jian is always able to speak up. With the continuous improvement and digging of the document library, a lot of information can be quickly deduced and derived after collecting it, providing effective assistance to specific investigation and infiltration actions.

For example, according to the analysis of the four parts, Qin Xiuyuan himself not only focused on eating gum, but also some research. It is said that he has high requirements for fragrance, and he will not want it if it is not in line with his preferences or has deviations in the mixing. Therefore, Qin Xiuyuan has always bought it in the same gum shop, and never pretends to be others but goes to the store to inspect the goods in person.

In this way, there will be the first sieve for things, which will siftly remove many speculations. One of the keys is: since Qin Xiuyuan’s gum is bought and inspected by himself, and he is more familiar with gum, how did the person who killed him deceive him if he really started with gum?

Shen Hao's thoughts were the same as those analyzed by the four parts: either Qin Xiuyuan lost the judgment he should have when taking poison, such as taste and smell problems. Or he could not tell it, so he accidentally ate it.

The case of the autopsy case has mentioned in the "first volume" that Shen Hao wanted to return to before. Although it is rough, it is still briefly mentioned about the general situation of the corpse, and it does not mention the problems with Qin Xiuyuan's sense of smell and taste.

Of course, the autopsy method in this world is much behind that in another world, but this autopsy situation can also be used as a reference. In addition, the eyeliner has not received any words that are damaged by Qin Xiuyuan's sense of taste and smell, including rumors. Basically, it can be ruled out that Qin Xiuyuan accidentally ate because of his lack of judgment.

The latter, "unable to judge whether true or false gum" is the most likely cause of death.

Shen Hao has never studied gum, and he doesn't even eat that thing. But he can compare gum to a "wine" he likes and studies some. Just imagine if someone wants to deceive him with a pot of fake wine and succeed, then the pot of wine must not be just "fake wine", but also "good wine".

It seems contradictory, but this is the fact. If you want to cheat experts, you must use 90% of the real thing as a guise and leave 10% of the fake ones to mix in. Otherwise, it will not be possible to succeed.

So what Shen Hao now asked the eyeliners spreading in the imperial city to be careful about is a gum shop called "Jin Fengyuan". Before Qin Xiuyuan died, he bought gum in this shop for many years. Moreover, this shop is very famous in the gum circle in the imperial city, and many dignitaries bought gum from them.

Keep a close eye on the shop, and you also need to follow the shop to find the workshop that makes chewing gum. Each store has its own recipe, which is "confidential" and is generally located in a farm outside the city. These are not difficult to check, but it takes time to slowly scramble to keep up with useful news.

However, Shen Hao certainly did not spend so much time on this case, and he needed to open a breakthrough as soon as possible. Moreover, he was sure that Qin Xiuyuan's death could definitely find a breakthrough in gum, and the murderer behind it must have nothing to do with the Qin family itself.

So an order came to Wang Jian and then to Zhang Liao.

Zhang Liao controlled the final part of the Hei Water Plan, which is the "Impermanence Department". It mainly implements the information collected and analyzed by the other three departments.

This time, the Impermanence Department was led by Zhang Xiao, and six people came to the Imperial City in batches in two days. Combined with the intelligence of the spy, they conducted a series of investigations into the shops and workshops of "Jin Fengyuan" and finally formulated a plan to infiltrate.

No matter how famous "Jinfengyuan" is, it is just a private store. Although there are many servants and warriors, including the workshop, as defense and some magic circles are used as guards, it is basically not difficult compared to the Impermanence Department, which has been specially trained for "insighting into various targets".

Infiltrating into shops and workshops is not about making money, but about printing books. Whether it is the materials entering and leaving the warehouse of the workshop, the finished products entering and leaving and flowing in the shop, as long as it is written by "Jin Fengyuan" as a record, all the things retained by Zhang Liao are in the task of Zhang.

It took a full two nights for a group of six people to finish the mission and bring back a three-foot-thick rubbing text.

The text does not require Shen Hao to screen and identify it one by one, so naturally there are four departments under Wang Jian to do it.

The four departments will screen out information that they think may have problems overnight and then feed them back to the Ministry of Impermanence for secondary screening and investigation. Then the results of the secondary screening will continue to provide evidence for the analysis of the other three departments. Finally, the final intelligence entries can be formed in such a repetition.

Shen Hao received a brief message from Wang Jian using the note of a thousand miles, one of which confirmed Shen Hao's long-standing speculation, and the details will be sent to the imperial city in the form of a copper bar to Shen Hao for his review.

There is no problem with the store accounts of "Jinfengyuan" and so on, or there is no problem with the kind of problem Shen Hao wants to find. There is no problem with the material entry and exit records of the gum workshop of "Jinfengyuan" and the "problem" is a sugar-making master in the workshop who receives a very high monthly money.

The reason why this person came into the sight of the four screenings was because he frequently extracted sugar-making materials in the material library of the gum workshop some time ago, but the number of finished products stored each time was somewhat different from his previous sugar-making efficiency.

A sugar-making master suddenly made a mistake. The people in the workshop would not have any opinions, and even if there was one, they would not say anything immediately. But is this person's "missing" time for the screening of the four departments? It just happened to be a few days before Qin Xiuyuan had an accident.

So I asked the Impermanence Department to investigate the sugar-making master. Although the person found it, he was lying in the mourning hall and had just died for two days. He said that he was drunk and walked away from the pond at night and drowned unexpectedly.

Dead? Two coincidences are overlapped together, even if the careless person is still feeling something is wrong. This sugar-making master died so strangely.

Then the things that were digging deeper fell on Zhang Liao and others. However, those who were not familiar with the place would definitely not be able to dig deeper into this kind of news for a day or two, and the necessary time would be too urgent.

Fortunately, Shen Hao is now in darkness and successfully pushed King Shou and the Ministry of Justice to block the sight of others. There is still time gap. At least he judged that it would take three or five days to find out the progress of the situation he has grasped. If there is any change in the middle, it will definitely delay it for a longer time.

"Prepare the car, go to the Ministry of Justice, I should urge the person surnamed Xue. Otherwise, he should be suspicious." Shen Hao smiled and joked with Wang Yiming. The latter was about to prepare the car, but unexpectedly, a small banner official from the Jingxi Funeral Office ran over.

"Is there something wrong?" Wang Yiming went up to meet him.
