I have a supermarket system, shocking the whole court

In modern times, with the development of technology, security surveillance and alarms may not be useful because there is more advanced technology that can crack these things.

However, in ancient times, surveillance and alarms were beyond the control of nature, and no matter who came, there was no solution.

It is indeed feasible to place surveillance and alarms in this place, but the wiring problem needs to be solved.

Unless there is a super powerful battery that can last for one or two years or even ten or eight years.

Ning Ning decided to go back and think about it at night.

Naturally, we can only talk about some insignificant things at this time, such as sealing the tomb passage first... no, the secret passage.

The deputy director nodded repeatedly and said that he would send someone over tomorrow to deal with the matter.

As Ning Ning continued to look around, there was another noise outside.

After a while, Qingfeng came down to report.

"The prefect is here."

Ning Ning raised her eyebrows. This gentleman was mainly in charge of Minzhou City. The Wuji Mountain Gold Mine was not under his jurisdiction. Under normal circumstances, he should not come here.

No one comes to visit for no reason. Is there something bad going on?

Ning Ning walked outside with a skeptical attitude, and then saw that not only had the prefect come, but he also brought a lot of things with him.

Ning Ning looked at the boxes of different sizes in confusion, and the prefect of Minzhou spoke politely.

"The gold mine was hit by a disaster before. In order to protect the important information and property of the gold mine from falling into the hands of evil people, I had no choice but to keep it temporarily. Now that the gold official has returned, I will naturally return the things intact."

The prefect was being polite, but the truth was that after Ning Zhongyi got into trouble, he sealed off this place and confiscated all the things here.

Now that Ning Ning is back, work has to resume here, so naturally the things have to be returned.

No wonder I felt that every place was empty when I was strolling around just now, especially Jin Guan’s lounge, which was bare and looked extremely poor.

Ning Ning thought it had always been like this.

It turned out that all of them were confiscated by the prefect.

But he was sensible enough to send it back in due time.

Ning Ning bowed to him to express his gratitude, and then asked the deputy manager to return the confiscated items to their original places.

She said she wanted to stroll around, and then left with Shang Wenqi and his party.

This is Ning Ning's territory. Not to mention strolling around, no one can stop her even if she wants to cook sheep and cattle and sing and dance here.

So everyone is just busy with their own things.

As for Ning Ning, she took Shang Wenqi and the others to find the tunnel.

There is no other way. This is the only clue of the thief who stole 100,000 taels of gold. He found nothing in the warehouse just now, so he can only hope for the entrance to the tunnel.

This is a dense forest, not far from the mine, but the grass is very thick. If someone were to sneak around here and do something bad, it would take a while to find him.

Ning Ning couldn't help but sigh: "This place is really dark under the lamp."

It's not far from the warehouse, but because of the dense grass, miners rarely come here. And you can see this place from the warehouse, so no one thinks that thieves will hide here and dig tunnels.

But someone actually did it, and succeeded.

I can only say that it is really dramatic. Success is indeed reserved for the brave.

However, this place had already been sealed off at this time. I think it was done by the prefect of Minzhou.

After all, one hundred thousand taels of gold were lost, and this place was under his jurisdiction, so he would definitely step in to manage it. However, even if he did, he would only send yamen runners to guard it, and no outsiders were allowed to approach.

After all, it was the Ministry of Justice that actually came to investigate the case.

This was a trap set by Liu Yanzhou, so even if someone was sent here, they would not investigate. Guarding here was just for show.

Ning Ning only hoped that they had not destroyed the evidence so that they could find some clues from it.

Apart from anything else, it would be good enough if they could figure out the route the gold thief took to escape.

Of course, there are two groups of gold thieves here. One group is the gold thieves sent by Liu Yanzhou to belong to the concubine, and the second group is the people who rob the concubine's gold.

Ning Ning wanted to investigate these two groups of people.

However, in order to catch them, we can only start with the Toffee's people. We need to figure out where the first wave of the Toffee's people retreated to, and then we can find traces of ambush from this route.

Unfortunately, nothing was found near the tunnel.

Ever since Ning Zhongyi was convicted of corruption, this matter has been put to rest in Minzhou.

Then the mine remained abandoned, the detectives who dug the mine withdrew and no one cared about it anymore.

It has rained a lot in the past two months, and wild animals have been roaming around. All in all, all traces have been wiped out and no valuable information can be found.

Everyone felt a little regretful.

"It seems that I can only use the dumbest method." Ning Ning sighed.

Everyone couldn't help but look at her, and for a moment they didn't understand what the dumbest method was.

"Isn't Zhou Qingming in our hands? By interrogating him, we can find out whether he was the one who took the 100,000 taels of gold, and who is behind him." Ning Ning spoke seriously.

Zhou Mingyu sighed: "It's hard to say anything about Qingming. He is very tight-lipped. If he doesn't want to say something, even if his teeth are smashed and his tongue is pulled out, he won't say it."

"Do you have any kind of poison that can make him tell the truth?"

Like truth serum or something.

However, as soon as Ning Ning said this, everyone looked at her in silence, as if they were looking at a fool.

Ning Ning sighed regretfully, it seems that it is gone.

"Even if we have it, we can't use it. The use of Gu is strictly prohibited in Daliang." Shang Wenqi poured cold water on her.

Ning Ning nodded regretfully. It seemed that she could only rely on Yiwu Small Commodities Market.

Speaking of truth serum, it is not a fantasy, but a real thing.

Around 1920, when an American obstetrician and gynecologist injected the anesthetic scopolamine into a patient, the patient entered a special state of calmness and answered questions accurately while unconsciously.

So people began to develop this anesthetic and then used it on various criminal suspects.

It turns out that it is indeed useful, but not absolutely. Overdose can cause people to become delirious or have organ failure, so it was rarely used for humanitarian reasons.

But that is only the information released to the public. In fact, in their mercenary circle, truth serum is still being constantly updated and is becoming more and more sophisticated.

But it’s not easy to get it. I don’t know if I can find it in the mall.

Ning Ning walked back and started communicating with the mall system, asking it to find a way to get it for her.

Then Ning Ning returned to the gold mine and waited for the end of get off work.

I have to say, if you really become a gold official in this place, life is actually quite comfortable.

To put it bluntly, she is just a vase decoration. She is not responsible for any heavy work, nor for any hard work. She is just like an overseer, clocking in every day, checking the attendance, and then urging everyone to make progress.

The work is not difficult, just very time-consuming.

After all, I have to stay here all day and can only go home after get off work.
