Wang Yi once again remembered the message he had received in the South 3 Stone Room before, and thought about the low combat power of those attackers in the iceberg that he had just speculated, and couldn't help but speculate whether it would be reinforcements sent by the original time and space.

The more Wang Yi thought about it, the more he felt that it was possible, and then asked Hongzhen, "What did you want to say just now?"

Hong Detective said bluntly: "The attackers inside are likely to be the living."

Wang Yi breathed a sigh of relief and said, "It's the same as I thought, and they are still living people with low combat power."

"In this case, then they are definitely not members of the cross-time and space forces or the Heavenly Dao Cultivators, although they don't know much about them, but their combat ability is not lower than our ordinary ghost soldiers." Hong Zhen was puzzled: "Which force does the living in the iceberg belong to?"

Wang Yi said calmly: "The key now is to determine whether they are alive or not, didn't you say that the attackers don't have the elemental aura that ghosts should have, can you be sure that they are really the living through this?"

"I can't." "The lack of sensing the elemental aura may be because our investigators are too far away from them to sense it."

"Can the scouts approach the attackers?"

"If you let the investigators force it, maybe it's possible."

"Is there any danger?" Wang Yi then thought that it could not be without danger, and asked, "What is the chance of success?"

"Ishei."

Wang Yi thought to himself that the success rate of Yicheng showed that the investigators were very likely to die inside, and he was not prepared to let the Silent Whisperers take risks, and the number of Silent Whisperers there was not much, and said: "Is there any other way to investigate the situation inside, under the premise of safety."

"This ......"

Wang Yi suddenly thought of the kind of detection tool he had designed not long ago, using drones to explore the distance under the deployment of missiles, and told him to tell Hongzhen about this idea, asking him to look for some materials to build simple drones in the nearby villages and towns, and then let the drones that can shoot fly into the iceberg and enter through the passages that were dug out in the iceberg before.

Drones do not possess elemental aura, and if the attacker in the iceberg senses an intruder through elemental aura, they will not be able to detect the drone.

Even if the attacker in the iceberg is not an intruder through the elemental breath, you can try to control its size during the construction of the drone so that it is not easy to detect.

Then you can build multiple drones and have the improvised missiles quickly propelle them directly to where the attackers are likely to be.

Macro understood what he meant, and began to arrange for people to collect supplies nearby.

Wang Yi thought that it might take some more time before the new investigation was made, so he got up and walked outside, and it didn't take long to walk to the monitoring wall.

In front of the monitoring wall, staring at the situation inside and outside the base was Chen Feng.

Chen Feng noticed Wang Yi coming over and asked, "Are you done over there?" What do you think? Have you ever found out how those humanoid lizards died? ”

"I only found out the time of their disappearance, what exactly caused their disappearance, I don't know yet, let's check it slowly in the future, there is something more important now."

"What?"

"Nanhong."

"There's something unusual over there?"

"Yes." Wang Yi sat down in a chair and continued: "Our scouts have already entered the inside of the iceberg, which is hollow, and the iceberg looks like a defensive shield."

Chen Feng also felt that the iceberg was like a defensive shield, so he was not curious about it, and asked, "What about the others?"

Wang Yi called up the filming of the inside of the iceberg, showed it to Chen Feng, and talked with him about the forces of the attackers inside.

After several discussions, two points were temporarily determined, one is that the attacker inside used a physical attack, and the other is that the attacker's combat power is not high.

After listening to his statement, Chen Feng analyzed: "It is not only the living who meet those two points, but also ghosts, such as ghosts with low combat power, they use weapons to enhance their own attack capabilities, as for the creation of weapons, it is possible to use the equipment in Nanhong City, and it is not impossible for ghosts to use tools to forge weapons."

"Of course." Wang Yi agreed: "It is not ruled out that the ghost can use tools to forge weapons, the problem is that the news we received before, the instructions given to us are Nanhong City."

"Do you still think that the attackers in the iceberg are the living? Is it the support we sent to us from that plane? ”

"I think it's very likely."

Chen Feng shook his head slightly and said, "Assuming that the attackers in the iceberg are the living, and they are the living who came from our original time and space, then how did they come here?" Although we don't know how we came to this plane, we do know that it is through the gate of time and space. Now that the gate of time and space is closed, can the living come here again? ”

"This ......" Wang Yi thought for a few seconds, and then contacted Xu Wu by communication, asking him if people or things in other time and space could still come to this time and space after the door of time and space was closed.

Xu Wu was just a ghost soldier in the Tiance Alliance, and he told Wang Yi that he was not clear about these issues.

Wang Yi dialed out Zhang Meng's communication again, and waited for a long time before she was connected, and told her about the problem just now.

Zhang Meng, who was on the other end of the communication, also said that he was unclear, and said that he felt that it was unlikely.

Wang Yigang's ignition of hope was extinguished by her words, and then said: "Then do you say that there is such a possibility, the door of time and space has been reopened."

"No way." Zhang Meng smiled lightly: "There are still negotiators in the Gate of Time and Space in the Heavenly Ce Alliance, if the Gate of Time and Space is opened, the Heavenly Strategic Alliance will not be unaware." What's more, even if someone really came to this plane through the gate of time and space, how did they get to Nanhong...... So what you found in Nanhong City is definitely not reinforcements from another time and space. ”

"Okay." Wang Yi sighed and said, "Could it be other living people in this time and space, not those cross-forces, but our locals."

Chen Feng continued: "It's impossible, didn't the company commander say it, we are the living here in Huameng, and the other two are in the north of Huameng, counting Zhang Meng, there are three in the north of Huameng, and we here, except for us, there is no one else, I think it should not be people in Nanhong."

"Ghosts?"

Chen Feng nodded and said, "It may be a ghost who is as good at using instruments as Old Man Lin and them."

Wang Yi asked: "Then what about the message we received before, didn't it guide us to Nanhong City?"

"I don't know, maybe I can only understand by investigating Nanhong City clearly." Chen Feng asked rhetorically, "How's the investigation over there?"

"Preparing."

Wang Yi then asked Hongzhen about his progress in the communication, and learned that he had collected materials and was building an unmanned reconnaissance aircraft.
