    The receiving IP of the encrypted email is located in the financial district in the city center. To be precise, it is a very stylish cafe on the corner of the financial district.

    Because the potential customers are all white-collar workers and business elites working nearby, the cafe has secured a dedicated broadband line and deployed wireless routers to provide wireless Internet services to guests.

    It was the fixed IP of the dedicated line network that allowed Gao Yue to find the physical location of the IP address effortlessly.

    However, through secret field investigations and background checks on the cafe owner and all employees, the possibility that it was an enemy stronghold was basically ruled out.

    In other words, the agents on Baodao just used their wireless network.

    It was hard to break the field door now. Looking at the densely packed office buildings, stores, and a large number of white-collar workers coming and going with laptops on their backs, I was dumbfounded.

    At this time, Gao Yue once again played a huge role.

    After work in the afternoon, when there were very few customers in the cafe, the field staff quietly took control of the situation.

    Then, Gao Yue entered the store like an ordinary customer carrying a laptop bag.

    After finding a seat and sitting down, I connected to the wireless network of the cafe, logged in to the router and checked, and found that the target IP address was still connected.

    The next work is very simple for Gao Yue. After finding the wireless network name of the IP address, he triangulates it by adjusting the signal connection strength when adjusting the receiving position.

    After locating the horizontal direction, go upstairs and use the same method to position the height.

    Finally, the location of the target device was locked in four rooms on the fourth and fifth floors of the second unit opposite the cafe.

    Considering that the power of the wireless router is limited, the other party must have a high-power directional antenna to receive the signal across a road.

    Furthermore, the directional antenna must be placed at the window and pointed in the direction of the cafe.

    The field team used binoculars to carefully observe the four suspicious rooms, and finally targeted a room with shutters on the fourth floor - 415.

    The building across the street is a commercial and residential building with small apartments. There are ordinary residents and some small studios or companies in the building.

    Through investigation and registration at the building management office, room 415 is rented out, and the registered use is warehousing.

    ??The renting time was five days ago.

    The field team did not take action immediately. After first confirming that there was no problem with the identity of the homeowner, they found the other party to understand the situation.

    According to the landlord, 415 was previously rented to a studio engaged in personalized wedding dress design.

    The studio was not managed well and closed down two months ago.

    Today, this kind of small commercial and residential mixed-use building is not very popular, so it is not easy to rent, so this room has always been idle.

    Five days ago, someone got the rental phone number he left from the building management office, claiming that he wanted to rent it out for a short period of time and use it as a temporary warehouse.

    Although the other party only rented for two months, the rent paid was very high. The landlord saw that it would be difficult to find a long-term tenant in a short period of time, so he happily signed a contract with the other party.

    When I handed over the keys, I saw with my own eyes that the tenant brought in a large truckload of cardboard boxes, large and small, light and heavy.

    I asked casually, and the other person said they were all office supplies, so the landlord didn¡¯t ask any more questions.

    After all, there are office buildings nearby. It is normal for someone to focus on the business opportunity of office supplies, and there is nothing to inquire about.

    The field team immediately brought in technical equipment to investigate the target room through the glass from the opposite building.

    It is basically certain that in addition to many completed cardboard boxes in the room, there is a small working server near the window.

    ¡°Otherwise, there was no sign of human activity.

    It can be inferred from this that the server is just a transit device to isolate risks.

    After receiving the information, it will be forwarded, and the forwarding method may be through a wireless network or a wide area network.

    In other words, the stronghold of those guys may be nearby or in any corner of the city.

    With complete uncertainty, in order to obtain more accurate information, Gao Yue began to try to invade the target server through the wireless network to find clues.

    It turned out that after a try, it was discovered that the target server used sandbox software, and based on the sandbox software, multiple virtual systems were working in parallel.

    Furthermore, multiple external wireless network cards are connected to the server, which are connected to several surrounding wireless networks.

    Each virtual system usually??, he was forced to rest, but how could he stay at this moment?

    After lying in the room for a while, I felt uneasy so I got up and left the room. As a result, I heard Gao Mei's obviously abnormal voice.

    Then he asked: "What happened?"

    "Something happened to Xiaoyue." Gao Mei didn't hide it any more and had a nasal voice when speaking.

    "What's going on? She's been watching the computer all day, why did something happen?" Liu Yi opened his eyes in surprise.

    The blacksmith was also surprised. After a while, he realized what Gao Mei wanted to say to him.

    ??Hurry and say: "Hurry over there, there are a few of us here."

    "No!" Gao Mei said in a very firm tone, trying to calm down his emotions, and said solemnly: "The task force cannot lock down the second group of Baodao in a short time. We must be prepared to deal with emergencies at any time.

    I have a hunch that the jounin from that island country will fight to the death!  "

    The blacksmith heard the determination in Gao Mei's mouth and knew that no matter how much he tried to persuade her, he would not leave her post without authorization.

    Then he turned to Liu Yi and said, "Wandering Soul, why don't you take a trip."

    Liu Yi waited for a while, and seeing that Gao Mei had no objection, he nodded and said, "Okay, I'll go there."

    ¡°Be careful when you move!¡± the blacksmith warned.

    Liu Yi turned around and hurried downstairs, waving his hand casually to express that he understood (Remember the website address: www.hlnovel.com
