The package that Han Feng bought contained four miniature receivers, two miniature signal transmitters, and a PDA.

Receiver and transmitter, Han Feng bought a few more sets, mainly because he was afraid that there would be a problem with one of them, so he used them for backup.

The PDA can be controlled for the receiver and transmitter, and can also be connected to the Internet and communication networks, which is an intermediate bridge between the receiver and the transmitter.

These are full-fledged spy devices that can be used right out of the box, but if they are to be used by pirates, they need to be properly modified.

The first is the launcher, because it has to be carried by pirates, so at least from the appearance of it can not be seen by others, otherwise it can easily be destroyed or taken away, or attract the attention of others.

Han Feng transformed the shape of the transmitter into an oval rubber pendant shape, the transmitter is wrapped in a leather case, with a button on the front, and there is an elastic device in the middle of the pendant, which can control the pull of the rope, Han Feng hung this thing on the dog collar around the pirate's neck, if the pirate wants to transmit any message, he can pull the pendant down, and then press the button to send the message.

On the inside of the collar, there is also a miniature receiver hidden, which can emit an extremely subtle sound, which is at the edge of the hearing range of the human ear, almost inaudible, and only pirates can hear clearly, and, for reasons of secrecy, it is also directly used Morse code for communication, anyway, pirates can easily understand.

The things in Han Feng's hands are mainly PDA, all his communications. It can all be carried out through this PDA master, and the operating system in this PDA is specially programmed to process the signals sent by the signal transmitter and convert the data into Morse code radio. Send a command to the receiver.

Originally, the PDA short and receiver and transmitter used Bluetooth to communicate, but the distance range is really a bit small, and if you want to increase the range, you have to specifically assume the antenna, which is too troublesome.

Han Feng then bought a miniature mobile phone of the latest style, and asked a professional to successfully transplant the key sending part of the mobile phone signal to the small transmitter, and the reason for the successful transplantation is mainly because the signal that needs to be sent is very, very simple, except for the authentication signal of one and the communication antenna, the main one. It's just the two signals that the Morse code needs. Of course, in practice, binary encoding is also possible. However, binary encoding is far less efficient than Morse code in terms of manual input.

Han Feng just made a request and then asked the other party to do it, as for some key intermediate steps, the other party didn't know. The guy in charge of the transplant was also weird. After all, in his opinion, such a transplant actually does not make any sense. Because even if he has a signal, if the movement is not supported, then this thing is no different from a scrap product. He didn't know that Han Feng had the ability to open up a special channel that would not be discovered by their staff directly from telecommunications and mobile ground signals, so that this little thing could work.

Because of this communication problem, Han Feng finally delayed his return to Beijing for two days.

Just returned to Beijing, Lin Zongsheng from the Virtual Simulation Research Institute of the Commission of Science, Technology and Industry for National Defense came to the door again, this time. He came alone, and came with full authority to discuss cooperation with Han Feng on behalf of their institute.

Han Feng met him in the conference room.

"Han Feng, I didn't know about Wang Qiangdi in advance last time, and his words and deeds do not represent our research institute...... On behalf of us, I would like to express my sincere apologies to your company if that incident caused any trouble! This time, this kind of thing will never happen again......"

At the beginning, the main thing is to help them solve some problems in their ongoing projects, and if the cooperation goes well, it will be possible to entrust some important orders to Liudu in the future, of course, there are also some ancillary conditions, such as confidentiality, and their technicians can study here, etc.

The military's orders, the price is very attractive, and the quantity is huge, plus Han Feng originally had this in mind, so the conversation between them went on very happily.

"Since your company is now an international company, I hope you can pay attention to the confidentiality of information......" Han Feng's background, he knows very well that his net worth is absolutely innocent, which is beyond doubt, but the employees of Liudu Company are not necessarily, so it is necessary to bring it up, "The developers responsible for the development of key modules of the project must meet our conditions and sign a confidentiality contract." ”

————

Han Feng nodded: "I understand this, in terms of the qualifications of developers, you have to be responsible for reviewing, after all, I don't know who meets the requirements." In addition, we can also decompose the development module into several small modules, and then give the corresponding input and output specifications, and distribute them to various staff for development, which can completely achieve the purpose of confidentiality."

Lin Zongsheng nodded clearly, a complex project is composed of countless small modules, if you only know one or a few of them, it will have no impact on the project at all.

"Moreover, we will set up a special department to develop military projects, and all the projects of this department are strictly confidential to the outside world, and the technicians you send can also develop ...... in this department."

The negotiations went smoothly and they signed a cooperation contract and a confidentiality agreement on the spot.

After that, Lin Zongsheng said: "The first project we cooperated on was the 'domestic fourth-generation fighter flight simulation system'. At present, domestic fourth-generation fighters have begun to equip the troops one after another, but the flight simulation training equipment supporting them has not been successfully developed...... The Air Force handed over this task to us two years ago, and two years later, there are still many key problems that have not been solved, resulting in the system not being put into use, and due to time constraints, this project must be completed as soon as possible, because this has become a bottleneck that restricts the development of the Air Force's combat effectiveness......"

Just when they were discussing the details of the project, Liang Jing brought him a shocking news - there was a sudden large-scale disconnection in the Sixth Degree Space!

Han Feng was taken aback when he heard the news, this phenomenon had never happened before, and he thought that there was a heavy **ug somewhere, so he could only hurriedly end the conversation with Lin Zongsheng and hurriedly rushed to the technical department to check the reason.

"What's going on?" When he came to the technical department, Han Feng immediately asked Liang Jing, "Have you found out the reason?"

"It's just a partial drop, and the technicians are now verifying it, and the results will be available soon. Liang Jing said, "There is no such phenomenon in the United States, mainly on our side, and the initial suspicion is that there should be a problem with the server." ”

On Liang Jing's computer, the situation of those users who dropped the line was marked in the form of coordinates, Han Feng looked at this picture and looked at the people for a while, and then said: "Beijing Telecom computer room." ”

Liang Jing was slightly stunned and asked, "What's wrong with the telecom room?"

At this time, the colleague in charge of verifying the server ran over and said: "Brother Jing, boss, it has been found out, the network of the server in the Beijing Telecom computer room has been interrupted, I just called them, and the other party said that the Ministry of Public Security has issued a special notice, saying that our server is suspected of spreading pornographic and obscene information......

Hearing this news, Liang Jing's face showed an anxious look: "How can they directly cut off the server we hosted there without even saying hello?"

Those few servers were purchased when there was no P2P technology in the past, and although the number of servers was greatly reduced, due to the narrow space of the Sixth Degree Headquarters, it has been placed there to host, but I didn't expect such a thing to suddenly appear.

There are indeed cases where someone in the personal space of the Six Degrees Space privately disseminates pornographic information materials, but the Six Degrees Space has been vigorously cracking down and rectifying, and encouraging users to report, once discovered, it must be to delete the account and block the other party's computer login. This is based on the hardware information and characteristics of the opponent's computer and the use of blocking technology,Unless the opponent is a very strong master,Otherwise, after blocking once,It is impossible to log in the second time,Unless you change computers。

In fact, there are also competitors who have maliciously reported this problem of Six Degrees Space, but because Six Degrees Network has always handled this aspect more properly, and the public relations work has also done a good job, this matter is not a big problem at all.

But now, for this reason, several servers have been cut off from the network, and the Sixth Degree Network Company has not received any notice or greeting in advance, which is too abnormal.

Han Feng's face was not very good at the moment, his first thought was to think of Wang Qiang, but then he was not very sure, after all, the cooperation between the Sixth Degree Network and their laboratory had been completed, and it was completely unreasonable for him to make any small moves.
