Where did Professor Zhongwen go?

Li Shanshan provided very limited information, and according to what she said, Han Feng preliminarily determined that Professor Li Zhongwen should be participating in a research project in the country, and only in this way can he explain why Professor Li agreed without hesitation and quickly completed the formalities.

Han Feng opened his notebook and sat in front of the computer and thought for a while, thinking about how to start finding Professor Li Zhongwen's whereabouts.

Based on such clues, it is indeed difficult to find a person from a place as big as China, but it is not without a little way, of course, there is also a bit of luck in this.

Professor Lee, an expert in the field of neuroscience, suddenly came to him because he published the last paper on nerve impulses?

Thinking so, Han Feng connected to the Internet, and then began to enter the relevant databases of major scientific research institutes to find out if there were any recent scientific research projects related to neuroscience.

After searching like this for a while, Han Feng suddenly thought that Professor Li Zhongwen was so secretive this time, and he didn't even tell his daughter, and the project he participated in should not be so simple, at least the probability of finding clues on the public network is almost negligible.

As a result, he turned to the Chinese network and entered some databases of military industrial institutions to find relevant information.

Because in his previous life, he was responsible for the construction of the entire military's internal network, so he has a very thorough understanding of the architecture of the entire network. Han Feng lamented in his heart that the military's construction in this area is really slow, and after so many years, the overall network topology has not changed, which is very dangerous. After all, after so many years, after continuous detection and inference, it is very likely that the master will completely sort out the entire organization - if the other party has the perseverance.

Han Feng searched all the military research institutes in 12 fields, including the aerospace industry, the weapons industry, and the nuclear industry, but he did not find a single research institute related to neuroscience, or even biological and chemical weapons research.

However, Han Feng knows that there must be research in this area. It's just that there may not be a clear establishment of specialized research institutes or laboratories like these military industries, after all, hidden laboratories. It also accounts for a large part of the entire research system.

In addition, there is another possibility, and that is to take into account the factor of confidentiality. Information in this regard. None of them are entered into the military network.

It is obviously unrealistic to search for information from so many institutes and laboratories. Han Feng simply doesn't have that much time and energy to do this, let alone that. There is also the probability that there is no useful information at all.

This path doesn't work. You can only change it.

Han Feng is back to square one again.

He stroked the sparse beard that grew from his chin with his right hand, thinking of another possible way.

He put his spotlight on Professor Lee. Find a breakthrough from him.

Because he has to investigate his location from the Internet, he can only think about the equipment on him that may be related to the network or something.

Han Feng's first thought was a mobile phone, if Professor Li still had his mobile phone on his body and turned it on, then he could directly find out where he was by directly using the signal indication area of China Mobile or Unicom.

Of course, Han Feng also knew that this condition was obviously not met, and Li Shanshan was so worried about him because he couldn't be contacted.

However, Han Feng still hacked into the data network of China Telecom, the operator to which Professor Li's mobile phone belonged, because he wanted to see if Professor Li had contacted those people before leaving the house, and if the other party had already called him before coming to the door, the clues would be clear.

So, Han Feng sent a text message to Li Shanshan and asked her for Professor Li's mobile phone number.

Li Shanshan replied quickly, obviously, she felt very strange about Han Feng's mobile phone number, and in the text message, she also explained that Professor Li's mobile phone was already unreachable on the day he left.

Because of the need to inquire about the relevant expenditure records afterwards, China Telecom will keep the customer's communication records for a long time, basically a phone card before the cancellation, all the data are recorded, which provides convenience for Han Feng to query Professor Li's call records.

In Han Feng's eyes, China Telecom's network is simply full of loopholes, he can come up with at least ten ways on the spot to easily hack into the other party's database system, and it will not alarm their security and defense alarm at all, in fact, Han Feng in his previous life, he had anonymously accepted the commission of China Telecom to detect network security vulnerabilities for them, and the final result was that they revoked the commission in advance

At that time, it was suggested that they completely redesign the entire network structure, otherwise, Wuding, it was still possible to be breached, in fact, Han Feng provided several high-risk vulnerabilities at that time, and any one of them leaked out would bring huge losses to Telecom. But this kind of major surgery, how can it be said to be moved, no high-level can take this responsibility, in the end, they can only maintain the status quo, use some indirect defensive means to hide and alleviate these loopholes, and give "Yue Feng" a huge amount of money, which is regarded as hush money.

Han Feng downloaded all the call records of Professor Li during that period and analyzed them one by one.

A large part of these phone records are calls from Professor Li's colleagues or students, and Professor Li rarely makes calls, usually to his daughter Li Shanshan, and it can be seen from these records that Professor Li is indeed a research-oriented person who has devoted himself to research, although he holds the name of the Department of Neuroscience, but his real interest and energy have always been academic. Perhaps it was for this reason that he resigned from the position of head of the department without hesitation.

Han Feng focused on the few days before he left, and analyzed the phone numbers that came in in detail, and from these numbers, although he did not find any special unfamiliar numbers, he found that Professor Li had spoken to a number four times in those short days, and this number was the president of Mizuki University.

Han Feng speculated that these phone calls should be Professor Li and the president discussing how to handle the resignation procedures.

But when it comes to the resignation of a professor who has been hired at a great deal of money and has just published a world-class academic paper, can the president agree to the resignation in just a few days?

This obviously doesn't make sense.

But if this is the case, there is only one explanation - the president is also an insider, or rather, he knows Professor Li's orientation.

Thinking of this, Han Feng also downloaded the principal's call records during that period of time and analyzed them together.

Eventually, he found a special number from the principal's call records - an internal number from the China Academy of Ordnance Sciences.

Han Feng knows the origin of this number, mainly relying on his identity in his previous life, due to the special kamikaze of "Yue Feng", at that time he was mainly responsible for the construction of the domestic military internal network, although he did not have access to any core secrets, but for some secret departments and institutions, he still knows better, so he knows the specific meaning of this special number.

"Weapons science?" Han Feng is very strange, how can it be a weapons scientific research institution?

I checked the time again, and it was very consistent with the actual situation, it should be that the other party contacted Professor Li first, and then Professor Li went through the formalities, and at this time, they said hello to the principal.

It seems that Professor Li did go to the weapons scientific research institute.

Is it true that Professor Li is really going to study chemical weapons?

Han Feng shook his head, this doesn't seem like Professor Li's character?

Han Feng checked and found that there are dozens of research institutes under China's weapons scientific research institutes, all over the country, and none of the information on the surface seems to be related to biological and chemical weapons.

So where did Professor Li go?

This clue can only go so far, and after determining the scope to the weapons scientific research institution, Han Feng once again returned to the original point.

In addition to the mobile phone, what other things can be connected to the Internet on Professor Li's body?

Han Feng thought about it for a long time, and finally reluctantly came up with a thing - a bank card. If Professor Li withdraws money from the bank, the records in the bank card will leave clues, so that the scope can be further narrowed. However, this probability is quite small, and who knows how high the level of secrecy is in his place, allowing researchers to move around at will?

This time, Han Feng hacked into China's major banking systems to find Professor Li's bank card information.

Now the data of major banks are basically shared with each other, for example, loans, you owe a loan in the Bank of China and deliberately do not repay it for a long time, but you have a lot of deposits in the Agricultural Bank of China, according to the regulations, the bank has the right to directly cross off the money of the Agricultural Bank of China directly from the card to repay the loan.

Han Feng was lucky, Professor Li was still able to go to the supermarket to buy things at will, and he finally found the credit card consumption record of Professor Li's Bank of China credit card, exactly two days ago, at a supermarket in Mianyang, Sichuan.

Mianyang, Sichuan?

According to this clue, Han Feng found a subordinate institution of the Ordnance Scientific Research Institute - 58 Institute of Southwest Automation.
