In the bedroom of Nanlin Guiyi's residence, he was operating the mouse and clicking on the specific location information in the map on the far right screen.

If you observe carefully, you can find that the map information on the screen on the far right is the map of the Toyoshi Shrine. The location information selected by Nanlin Guiyi almost covers the entire scope of the Toyoshi Shrine.

"Butler, lower the drone's height, activate the infrared thermal sensing camera, and scan the humans in the East Shrine." Nan Lin Guiyi ordered.

The drone lowered its hovering height and finally hovered at a height of 20 meters. Because it is an electric-powered drone, coupled with the excellent duct design and silent propeller design, the drone is not very noiseless.

Twenty meters high, it is hard to hear!

However, if there are people on the ground, a height of twenty meters will definitely be discovered!

Fortunately, Chiba Qikai chose the time to be close to ten o'clock in the evening. The Toho Shrine has been closed. There are no tourists inside the shrine. The drone is suspended at a low altitude of 20 meters, so there is no need to worry about being discovered.

After all, during the descent, infrared thermal sensing cameras found that there was only one person's thermal radiation image inside the Toho Shrine.

Nanlin Guiyi could not determine whether that person was the mysterious person behind Chiba Qihai or the night-time staff at the Tokio Shrine.

However, no matter who it is, it doesn't matter, because the other party will not find drones in the room inside the shrine.

Nanlin Guiyi continued to instruct, "Butler, control the drone and perform precise throwing operations."

"I understand." After Butler replied, he controlled the drone and continued to lower the altitude, lowering it ten meters again. When he was about ten meters away from the ground, under Butler's control, the drone began to throw small objects placed before Nanlin Guiyi.

The outside of those small objects is wrapped with a layer of plasticine like mud, which is comparable to a thumb's head. They are difficult to detect under the cover of night.

In fact, all those small objects are Bluetooth microphones!

After Nanlin Guiyi connected them all to each other, they connected to the Bluetooth frequency band of the drone, and then distributed almost evenly in the Dongji Shrine. Through these Bluetooth microphones, Nanlin Guiyi created a monitoring area covering the entire Dongji Shrine.

"Sir, complete the precise throwing operation." Butler reported to Nanlin Guiyihui.

Nan Lin Guiyi smiled and said, "Land on the top of the main building of the Dongfeng Shrine!"

As the drone landed on the roof of the main hall of the Toyoshi Shrine, the entire Toyoshi Shrine returned to peace, as if nothing had happened. However, not nothing had happened. Nanlin Guiyi turned the Toyoshi Shrine into the home court!

At 10:15 pm, the security surveillance camera near the Tokushi Shrine once again discovered Chiba Qikai. Her destination was indeed the Tokushi Shrine.

Nan Lin Guiyi’s guess is not wrong at all!

Qianye Qihai appeared. Will the mysterious person hidden behind her still appear?

Nan Lin Guiyi waited patiently. As long as the mysterious person behind her appeared, Nan Lin Guiyi would conduct direct inquiries at the Tokyo Metropolitan Population Information Statistics Bureau.

The Tokyo Metropolitan Population Information Statistics Bureau has the authority to access the National Population Information Statistics Bureau of Japan. At the same time, Nanlin Guiyi has the highest reading authority of the Tokyo Metropolitan Population Information Statistics Bureau.

It is not that there is any special identity in Nanlin Guiyi, but that Nanlin Guiyi has penetrated the system of the Tokyo Metropolitan Population Information Statistics Bureau, obtained the permissions of the super administrator, and hid the permissions of the super administrator.

Unless the Tokyo Population Information Statistics Bureau’s system is offline and conducts closed security inspections. Otherwise, as long as the Tokyo Population Information Statistics Bureau’s system is online, even if it is conducting security inspections, Nanlin Guiyi will receive a notice and process it in time.

Chiba Qihai walked to the gate of the Tokushi Shrine. With the help of the last security camera facing the gate of the Tokushi Shrine, Nanlin Guiyi discovered that she had entered the Tokushi Shrine.

The Dongyu Shrine has no door locked!

It seems that there are also participations in the Toku Shrine? The guy who stayed in the Toku Shrine, even if he was not a mysterious person hiding behind Chiba Qihai, was also from their group!

After Chiba Qihai walked into the Tokyu Shrine, she stopped in the open space in front of the main hall, and she waited patiently.

In less than five minutes, Nanlin Guiyi discovered a suspicious person through security surveillance cameras around the Dongji Shrine.

Why are suspicious people?

Because that guy, wearing a baseball cap and slightly lowered his head, always chose to walk under the shade of the tree, obviously avoiding the camera. At the same time, based on the other party's route of travel, is the destination of Toho Shrine?

Therefore, Nanlin Guiyi locked the other party as a suspicious person!

‘Male, height 175cm to 178cm, weight 60-70Kg, age cannot be judged for the time being, identity cannot be judged for the time being.’ Nanlin Guiyi records basic information.

Although Nan Lin Guiyi did not obtain the key information, he was not in a hurry. Waiting for a while, the good show was about to be performed!

In less than two minutes, Nanlin Guiyi found from the last camera facing the Dongji Shrine that the suspicious person had indeed entered the Dongji Shrine and disappeared into the remote monitoring.

However, the suspicious people and Chiba Qihai are still within the monitoring area arranged by Nanlin!

Nanlin Guiyi has tested the Bluetooth microphone array, and through the environmental noise reduction algorithm and the lossless volume gain scheme, if necessary, Nanlin Guiyi can even clearly hear the breathing of Qianba Qihai.

This is the charm of technology!

Through technological means, surreal effects that are almost as magic and metaphysics can be achieved!

Isn’t the Bluetooth microphone array similar to the mythical Shufeng ears?

"Butler, turn on the adaptive volume control adjustment and turn on the full recording." Nanlin Guiyi instructed Butler to let Butler automatically adjust the volume so that the volume is always at the most comfortable level.

As for the entire recording, it is to avoid listening to the details when Nan Lin Guiyi overlooked.

Nan Lin Guiyi wore high-fidelity headphones. Based on the footsteps and breathing sounds feedback from the Bluetooth microphone array, Butler virtually constructed the locations of the suspicious person and Chiba Qihai in the map information on the far right screen.

The suspicious person came to the vicinity of Qianye Qihai. The distance between the two was about one meter or two meters.

The power of technology was once again revealed, and based on sound alone, it simulated and restored the locations of Chiba Qihai and the suspicious people.

In the high-fidelity headphones, Qianba Qihai suddenly heard the voice of "No.4, you are late!"

"It's just one minute." No.4, which is obviously code-named, responded. Through voice analysis, he should be a middle-aged man.

Listening to the conversation between the two, especially when Qianye Qihai called out the code name of the suspicious person, Nan Lin Guiyi frowned...
