The Silent Whisperers eventually built five micro-drones equipped with cameras to capture the footage, and all that was left was to send the drone to the inside of the iceberg.

Hongzhen began to return with the Silent Whisperers and the newly built unmanned reconnaissance aircraft, and soon returned to the place where the channel was dug in the iceberg before, preparing to send the unmanned reconnaissance aircraft to the inside of the iceberg.

At this moment, Wang Yi and Chen Feng were still staring at their movements in front of the monitoring wall, eager to know whether the attackers inside the iceberg were humans or ghosts, and which force they belonged to.

Hong Detective chose one of the passages that he had made on the iceberg, and then asked Wang Yi by communication: "Sir, do you want to send the reconnaissance plane into the iceberg now?"

"Let's get started." Wang Yidao.

"Yes."

Detective Hong pointed to the two silent whisperers with reconnaissance planes, and when they were out of the ranks, he pointed to the reconnaissance team of ten people, and ordered them to move towards the passage not far ahead, and then stand by in the passage two kilometers from the hollow area of the iceberg.

The silent whisperers who received the order quickly moved up, and after a quarter of an hour of flight, they reached the location that the detective had said, made a brief report to the detective, and asked for instructions on what to do.

Hongzhen asked them to start the unmanned reconnaissance aircraft at the position they were at this time, and let the two drones fly alone to the hollow area in front of them.

The unmanned reconnaissance aircraft slowly rose under the operation of the silent whisperer, and rushed to the destination at the speed of an ordinary person's 100-meter sprint, and the camera function on it had been activated, but the lighting had not yet been turned on, so the shooting picture transmitted to Hong Detective and Wang Yi was only pitch black.

Through the remote control terminal of the unmanned reconnaissance aircraft, Hongzhen can see their real-time location, including whether they have entered the hollow area.

After four minutes, the unmanned reconnaissance plane reached the neutral area, and under the remote control of the macro reconnaissance, it turned and flew diagonally downward, but it did not fly for half a minute before it encountered the attack of the orange light.

Hong Zhen and Wang Yi only saw the golden light that appeared in the shooting frame, followed by the words "signal interruption".

Hongzhen reluctantly reported to Wang Yi: "Sir, our drone can't avoid the attacker's attack."

"See." Wang Yi thought about it: "Next time, set the flight trajectory of the drone to an irregular trajectory."

"Irregular tracks?"

Wang Yi explained: "It is to let the drone fly east and west, like a headless fly, so that the attacker cannot determine the direction of its flight."

"Understood, I'll arrange it."

Hongzhen didn't want to wait any longer for the reconnaissance team that had not yet returned, so he rearranged a team of ten people and ordered them to bring the last three unmanned reconnaissance planes.

The new reconnaissance team also activated the unmanned reconnaissance aircraft two kilometers away from the hollow area, and the rest of the route went alone to the unmanned reconnaissance aircraft.

When the unmanned reconnaissance plane did not arrive at the hollow area, it was moving in a straight line along the passage, and the moment it flew out of the passage, it began to change its flight direction continuously, and generally moved towards the buildings in Nanhong City in order to find the attackers who released their attacks there.

Wang Yi saw only pitch black through the monitoring wall at this time, although he couldn't see the progress of the drone, but as long as there was no kind of orange gold line attack, the drone was moving forward smoothly, but he didn't let go.

Although the attacker has not made any action at the moment, the attacker must have noticed the unmanned reconnaissance aircraft flying into the neutral area, just like last time, the lack of action may be due to the inability to lock the direction of the drone's flight.

In this way, it should be that adjusting the flight direction of the drone has played a role.

Wang Yi didn't dare to relax and stared at the drone shooting frame, and soon saw countless golden line attacks flashing in the shooting frame, and it didn't take long for the connection with those unmanned reconnaissance planes to be interrupted.

The macro detective on the other end of the communication also quickly made a report on the failure of the reconnaissance and asked for instructions on what to do next.

Wang Yi pondered for a moment, and then said to the communication: "Missiles, use simple missiles to carry cameras, and then launch them at the positions where the attackers may be, the more the better, you can only equip some missiles with cameras, and the others as feint attack bombs."

"Yes, just ......"

Wang Yi saw that he was hesitating, and couldn't help asking, "Is there any problem?"

Hongzhen said respectfully: "Sir, it may take a long time to build a missile with our manpower here, and it is difficult to control the direction of the missile's flight."

"Don't be so troublesome, I'm talking about improvised missiles, which are equivalent to rockets, and it's enough to be able to quickly approach Nanhong City in the iceberg."

"Understood, I'll arrange it right away."

Wang Yi in front of the monitoring wall had no choice but to continue to wait, chatting with Chen Feng about the monitoring inside and outside the base while waiting.

Chen Feng said that there are still ghosts waking up in the southwest and southeast directions outside the defense area, with an average of about 30 per hour.

The ghosts who woke up were also heading towards the base, and because there were not many of them, they didn't pose much danger and wouldn't have much impact on the mission of scouting the Stone Chamber Group.

It didn't take long for Ma Yuanliang and their communications in the stone chamber group to be called, and Ma Yuanliang learned about their situation there, and learned that their actions were quite smooth, and the 1022nd stone chamber had been explored.

At present, Ma Yuanliang and the others still haven't found the first batch of ghosts who entered the stone chamber group, and of course they haven't been chased by the ghosts who rushed to the stone chamber group later.

Wang Yi saw that there was no abnormal situation in Ma Yuanliang, and he was relieved, and there was nothing to worry about outside the base for the time being, so he put his mind on the reconnaissance of Nanhong City.

The macro reconnaissance in Nanhong City has already collected the materials to build improvised missiles, and after more than four hours of processing, a total of 300 missiles have been created.

The improvised missile is 1.7 meters long, 20 centimeters in diameter, grayish-black in color, and is carried by the silent whisperers in groups of six.

Hongzhen commanded all the silent whisperers around him to rush into the three passages leading to the inside of the iceberg, and stopped moving forward one kilometer away from the hollow area, and if they went further, they might encounter the attack of the attackers inside the iceberg, but the improvised missile could not move forward in a curve, and it was impossible to hit Nanhong City inside the iceberg at this time.

After thinking about it for a moment, the detective decided to continue advancing towards the hollow area, and all the Silent Whisperers moved slowly at his request, ready to fire the improvised missiles at any time.

The Silencers are getting closer and closer to the hollow zone, ready to be attacked by attackers at any moment.
