Theoretically, regarding the murder of Cao Qing, Rosen does not need to draw his own conclusions and catch the murderer.

According to his assumption, as long as he interrupted his cultivation of the three thousand weak waters, he would be able to return to Earth.

No matter how bad it is, he can also get the working group to force itself to wake up.

Then, just like when the serial rape and murder case was solved, Rosen only had to write down the final inference from the task force and inform Lin Qianjun of it.

But before that, Rosen still has a lot of work to do.

For example, collecting information.

It is difficult for a good woman to cook without rice.

Those dramas that can judge who the murderer is just by watching the scene will only appear in film and television dramas.

Even for the best criminal investigation experts on the planet, solving a crime needs to be based on the integration and analysis of various information.

Collect eyewitness statements.

Establish a timeline of the deceased's pre-crime crimes.

Sort out the deceased's potential enemies.

The murder weapon and the body itself were examined.

Etcetera.

Rosen is not a serious criminal policeman, he has never received formal training, but fortunately, Rosen's father is a detective, fortunately, when the serial rape and murder case, he read the file report presented by Zhan Linwen, fortunately, after returning to Earth, the gods of the task force analyzed the case for him in detail.

So in general, Rosen still knows what he should do.

He set his first investigative target on the butler.

Cao Qing lost his wife at an early age and had two sons, but neither of them was in Xuzhou Mansion.

The eldest son was an official in Yizhou, while the younger son was favored by a small sect and focused on cultivation.

On weekdays, all the big and small affairs in the house are taken care of by this housekeeper named Ma Xiankui.

Therefore, if you want to say who knows Cao Qing best, it must not be Lin Qianjun, but the horse steward of Cao Mansion.

Lin Qianjun did not stay in Cao Mansion for long, and after handing over the power to Lawson, he left, thinking that he was going to the adjudication department to maneuver, while Pan Shi waited by Lawson's side, listening to his orders at any time.

The garrison killed a flag officer, and he was murdered, the impact of this matter was too bad, and it was a great blow to the entire garrison, and even the entire Xuzhou Mansion, so at this time, Pan Shi couldn't care about Rosen's power at all, all he needed to do was cooperate.

Cooperate with Lawson to find out the truth of this case as soon as possible.

Rosen found a guest room as an interrogation room, and asked Pan Shi to control the people of the Cao Mansion first, and let him question them one by one.

The first person to walk into the room was naturally Steward Ma.

"You just said that except for yesterday, Captain Cao Qi has nothing abnormal in the past few days, and he is still the same as before, he went to the camp to report in the morning and returned to the mansion for dinner at dusk, right?"

Steward Ma nodded: "Yes." ”

"What about today?" Lawson picked up a brush and wrote on the paper: "When Captain Cao Qi said that there were guests visiting today, did he have any suspicious behavior?"

Steward Ma wiped the cold sweat from his head and muttered, "If you have to say that the master is different from usual, it is that he told us subordinates to avoid it." ”

"Hmmm......"

Rosen nodded, this is an obvious thing, otherwise it is impossible for Steward Ma not to know who is coming.

"Is this rare?"

Steward Ma hesitated for a moment and replied, "Usually this is only done when the lord receives distinguished guests, but it is indeed not very common. ”

"Your Excellency," Rosen pondered for a moment, wrote it down on a piece ......of paper, and then said, "Then as far as you know, has Captain Cao Qi caused any enemies recently?" or encountered any trouble?"

Steward Ma shook his head, and said in a low voice: "If you have to say that there is, it is, it is Lu Duwei in the garrison......"

This is nothing new for Rosen, so he can't help but be a little disappointed.

Then he thought of a clue from before, and asked Ma Xiankui: "You mentioned to me before, saying that Captain Cao did not eat at home yesterday, but went out to party with friends, and when he came home, he still smelled of alcohol, do you know where he went?"

Hearing this, Steward Ma subconsciously swallowed his saliva and replied cautiously: "It should have gone to Lord Pan's house, and the other two flag commanders are also there." ”

Lawson was stunned, looking a little surprised.

The four flag commanders of the garrison are having a private dinner, does Lin Qianjun know?

It's not like a clique, but it always feels weird......

"So when was the last time you saw Captain Cao Qi tonight?"

"When I was a child, my lord ordered me to make tea and send it to the room, and I haven't seen him since. ”

Rosen nodded and said, "Okay, you go down first, and let Master Pan call those two maids in." ”

"Yes. ”

Steward Ma nodded his head again and again, and then left the room.

Not long after, Rosen saw Pan Shi come in with the two maids who had appeared outside the window of the crime scene before.

But this time, Rosen did not rush to ask, but let the two maids into the room first, and he himself walked out.

"Master Pan. ”

"Huh?" In the face of Rosen, Pan Shi didn't mean to take a stand at all, even if this person was his subordinate not long ago, now he is on an equal footing with himself, and even more trusted by Lin Qianjun.

"There's one thing I'd like to check with you. ”

Pan Shi nodded: "You say." ”

Speaking realistically, although Pan Shi is much stronger than Lawson in terms of cultivation, and his qualifications in the garrison are not something that Lawson can catch up with for a while, but if it is only about solving the case, he is indeed not as far as Lawson.

After all, he is the flag commander of the garrison, not the judge of the division.

There is a specialization in the art industry, and this is the reason.

Therefore, at the beginning, when Lin Qianjun ordered Rosen to investigate the case with full authority, Pan Shi was still a little shocked, but when he came back to his senses afterwards, he felt that this seemed to be a matter of course.

If Lin Qianjun had asked him to be in charge of the investigation, I am afraid that Pan Shi's eyes would have been blackened.

So now anyway, whatever Rosen tells him to do, he just does as he says.

Strive not to make mistakes.

Even if the case can't find out the reason in the end, it is not him who loses points on Lin Qianjun's side, but Lawson.

At this time, when he heard that Lawson was going to ask him, Pan Shi was not very resistant in his heart, but was mostly curious.

But then, a look of embarrassment appeared on his face.

Because Rosen's question is somewhat difficult to answer.

"According to Steward Ma, last night Captain Cao Qi went to your mansion and didn't return drunk until late at night, I would like to ask Master Pan, what special words did Captain Cao Qi say at that time? What is the reason for you to invite Captain Cao Qi to go?"

Pan Shi looked embarrassed, and after pondering for a moment, he smiled bitterly: "This matter should have nothing to do with the death of Cao Qichang, right?"

Rosen smiled: "It doesn't matter, I only know when Master Pan says it." ”

Hearing this, Pan Shi couldn't help coughing dryly, and then said: "If there was anything unusual about Cao Qichang that day, anyway, I didn't find out, everyone was very happy at the time, and no one had a conflict during the period, so Cao Qichang was happy......"

"So......" Rosen continued, "what exactly did the four of you talk about at the wine table?"

When the words fell, the embarrassment on Pan Shi's face became a little stronger: "It seems that you know everything?"

Rosen shook his head: "I only know that in addition to you and Captain Cao, the other two Flag Commanders are also present. ”

As soon as these words came out, Pan Shi couldn't help but look extremely entangled, it seemed that there was something unspeakable, and it seemed that this matter was not appropriate.

Seeing this, Rosen suddenly deliberately straightened his face, and said in a deep voice: "Lord Pan should have heard it just now, when Lin Du ordered me to investigate this case, he promised that he could ignore any consequences and not do anything evasive, if Lord Pan deliberately concealed the issue about Chief Cao Qi......"

"Okay, okay......" Pan Shi spread his hands helplessly, lowered his voice and said: "Actually, it's nothing, the person we talked about the most at the wine table that day was actually you." ”

"Me?"

Lawson was stunned, not knowing how to react for a while.

And Pan Shi showed a look of "I knew this was the case", and said with a wry smile: "Luo Jiaoxi, you should know that in our garrison, it is a place that pays great attention to qualifications, and you have been the Duwei as soon as you came, which has caused many people to be dissatisfied, and now the Lord Dutong has promoted you to such a high position, and several of our flag commanders are quite worried about this......"

Speaking of which, Rosen has thoroughly understood, and it has been like this for a long time.

To put it bluntly, the four flag chiefs felt that they had climbed too high and too fast, and they were not convinced.

It doesn't seem to have much to do with Cao Qing's death.

Unless the killer is Rosen himself......

Well, it seems that this clue is also heading for a dead end.

"I see, I know, so Xiang Qi Chang and Zhou Qi Chang haven't arrived yet?"

Pan Shi shook his head: "The mansions of the two of them are a bit far away from here, and it will probably take some time. ”

"Good. When the two of them arrived, they asked Master Pan to summon them here. Rosen nodded, and the topic was cleared up.

Pan Shi nodded yes, and seemed to stop talking.

And Rosen comforted: "Don't worry, I won't tell Lin Dutong about this matter." ”

"That's good, that's good......"

Rosen smiled wryly and shook his head, and returned to the room, where he saw the two maids shivering.

He raised his hand and rubbed his face, trying not to let Pan Shi's previous words affect his emotions, and then slowly came to the table and sat down.

"Don't be nervous, just tell the truth about what you know. ”

"Yes, it's big, my lord. ”

Rosen picked up the pen, looked up at the two of them, and asked, "Are you two the corpses of Cao Qichang found at the same time?"

The two nodded in unison.

"Good. Rosen carefully jotted it down, and then said, "So what are you doing before this, I want you to tell me the whole process of finding the body, try not to miss any details, well, you say it first." ”

Rosen raised his hand to the maid to his left, and was about to listen to the testimony of witnesses, when suddenly a noise came from outside the house, and then the door was pushed open.

"I didn't say it......" Lawson looked up dissatisfied, but he was stuck in the middle of his words.

"Wu Xiang, why are you back?"

I saw Wu Xiang panting heavily, standing outside the door with an anxious face, with some self-blame in his eyes.

"My lord, Lu, Lu Xuan was arrested by the people of the Ruling Division!"
