The identity background of tonight's attackers was not ordinary, they followed Qin Tianyuan all the way, and waited until they got to the right place before making a move.

And in order to prevent detection by the monitoring network, they invaded the data network in advance, cut off the municipal monitoring information, and repeatedly played the pre-recorded video signal.

This is not something that ordinary people can do, and the municipal network is the government's private network to manage the operation of the entire city. In addition to the issuance of daily executive orders, all relevant information of various agencies such as transportation, fire protection, and security is transmitted through this network.

If the city is compared to a person, it is the nerve of the whole city, transmitting and collecting signals to the body, and finally the data is aggregated to the brain, the municipal server.

There is a super artificial intelligence on the municipal server to handle it, and basically all the regular affairs of the entire city are managed by this super artificial intelligence.

Therefore, the municipal network is a part of the city's infrastructure, and it is a very important part, with a very high level of security.

Intrusion into municipal networks can be regarded as terrorist attacks, and even hackers who are not quite mentally healthy dare not touch this brow, which will be wanted by the whole network.

Unexpectedly, these people were so rampant, not only invading the municipal network, but also arranging a well-trained backup force, and in the event of an accident, they did not hesitate to use force to meet their retreat.

Even a well-organized large criminal group may not have this strength, and even if it does, it does not have the guts.

So the identity background of this group of people is really very strange, and some things are extremely scary to think about.

This group of people came up and asked Qin Tianyuan for something, but they didn't say what it was.

What is it that makes these people so aggressive?

Although there was no evidence, Qin Tianyuan instinctively felt that tonight's attacker had something to do with Wei David's matter. Because he is a small private detective, he has nothing to do with anyone.

The only trouble is that it may be caused by competition with their peers, but those of them who go around asking about people's gossip and peachy news can't do such a thing as armed kidnapping and invading municipal networks.

The disgruntled client is even less like it, who is so entangled when paying the bills one by one, and is definitely not willing to spend money to hire a group of people to trouble him.

Then the only thing that can make him get into trouble is Wei David, the two people who were fat and thin at the scene of the crime were obviously also going for Wei David.

I just don't know the purpose of those two people, and I don't know who sent them.

However, no matter what kind of people these two living treasures are, it shows one thing, they didn't want to kill Wei David.

Because these two people want to be street thugs more than they want to be killers. No matter how you look at it, it's extremely unprofessional, brainless and unhappy, no matter how you look at it, you don't look like a good person, the goal is too obvious, and it's easy to be suspected.

As soon as he came up, he used knives and guns, obviously the kind of thugs who are used to solving problems by violent means, the level is not high, and the head is not very bright.

If there is something important, no one in their right mind will choose these two people to do it.

These two people had also threatened Qin Tianyuan with a knife at the scene and asked him to hand over his things, but Qin Tianyuan was too nervous and didn't pay too much attention to this sentence.

In retrospect, it seems that these two men were also looking for something.

Thinking of what happened tonight, if you say it was just a coincidence, then Qin Tianyuan felt that he could immediately draw out ten consecutive SSRs without kryptonite, which was essentially a failure to wake up.

If these people are all looking for the same thing, then here's the problem.

What are these people looking for?

Thinking of this, Qin Tianyuan suddenly recalled the sentence that Wei Dawei shouted when he died, "Not here?" ”

What's not here?

Is it human? Or is it a thing?

There are too many mysteries in the whole matter, and Qin Tianyuan's head hurts.

Originally, after the police took over this matter, it had nothing to do with him. As a result, a group of psychopaths popped up tonight, and they opened their mouths to ask him for something.

He felt that the gang must have gone in the wrong direction, and he didn't take anything.

It's a pity that those people didn't agree with Qin Tianyuan's idea.

Will there be endless troubles in the future, this is even more disgusting, anyone who has nothing to do with this will feel annoyed, and it will be life-threatening.

Thinking of this, Qin Tianyuan turned over and began to search his room everywhere.

He felt that he should find some guys to take advantage of and use them as weapons for self-defense, but he couldn't be blocked by people like today.

As a result, after turning around, except for the kitchen knife and fruit knife in the kitchen, only a few gym equipment were found, and there was no iron tool left.

Qin Tianyuan felt that he had lived too comfortably before, why couldn't he even find a commonly used self-defense tool.

However, when he was rummaging through the wardrobe, Qin Tianyuan found a locked iron box, which was also an unexpected gain.

The iron box is exquisitely made, with a matte black surface and a set of five-digit mechanical combination locks on it.

I knocked on it casually and found that the material of the whole box was very strong, and it looked like there were some valuable things stored inside.

This made Qin Tianyuan a little curious, he didn't remember that he had such a box, and he didn't have any impression in his mind, but this did not hinder his interest.

If it's the private money that was hidden before, or some kind of treasure, wouldn't it be rich?

After Qin Tianyuan studied the password lock, he tried to use his birthday, but it didn't open it, which made Qin Tianyuan feel a little surprised.

Now it's troublesome, if it's not your birthday, then what will the password be?

Qin Tianyuan thought back to his habit of using passwords, tried a few common ones, and still didn't open them, which made him very frustrated.

The other world has different habits, so it is extremely difficult to open this lockbox.

There are only a few sets of numbers that are important to you, your birthday, your parents' birthday, and your lover's birthday...... Oh, and there is no lover, there is an option to remove it.

So the most important number left is your bank password, but it's a six-digit password, and this five-digit password can't match?

Finally, when Qin Tianyuan was about to give up, he looked up and saw the digital calendar on the wall.

His heart moved, and he hurriedly entered the date of his crossing into the combination lock.

With a "click", the lockbox opened.

When you open the lid, you are greeted by a notebook wrapped in cowhide.
