Wang Yi understood what Hongzhen had just said, but what he didn't know was the specific situation, and which forces were the attackers in the iceberg, and what happened to the silent whisperers who were on a mission to investigate the iceberg at this time.

Wang Yi couldn't guess the combat ability of the attackers, and he couldn't determine whether those silent ones had disappeared, so he hurriedly decided to let the macro detectives outside the iceberg distance themselves from the iceberg, in case they encountered any more accidents.

Hong Zhen immediately took the remaining silent whisperers and began to raise the altitude, and soon stopped at a height of five hundred meters above the ground, and then asked Wang Yi for instructions: "Sir, are we going to continue to investigate?"

"Don't be in a hurry, wait for the group of silent whisperers who just entered the iceberg."

"Yes."

Wang Yi observed the video footage transmitted by the macro detective, and focused on the entry point of the silent whisperers in front of him into the iceberg, worried that a large number of ghosts would suddenly emerge there, and then the war machine of the Cloud Pavilion, so as to remind the macro detective to be vigilant in the communication, if the ghosts were found to rush out of the iceberg, they would immediately retreat at that time.

More than twenty minutes passed quickly, and the outside of the iceberg was still calm, and there was no abnormal movement in the passage that had been dug out before.

Wang Yi simply calculated the time, it took twenty minutes for those silent whisperers to dig into the iceberg from the outside, and if they withdrew from it, it would definitely take even less time.

It had been more than twenty minutes since they had been attacked, and yet they had not yet been seen flying out of the iceberg.

Wang Yi raised his heart for this, worried that they had died in it, and after waiting for more than ten minutes, he still didn't see the Silent Whisperer fly out of the iceberg.

The macro detective on the other end of the communication asked, "Sir, what should we do now?"

Wang Yi rubbed his forehead with his hands, and he hadn't thought about what to do next, although he found that there were problems in the iceberg, but judging from the current situation, it was difficult for the remaining macro detectives and their people to continue to investigate the inside of the iceberg.

Wang Yi was even more puzzled by the message he had received in the South 3 Stone Room before, and the message referred to Nanhong City.

If that message is true and reliable, then its sender is Zhang Xuesong, who is located in the original time and space, and the key hint given in the message is Nanhong City.

At that time, it was judged that the information was incomplete, and it did not indicate what Nanhong City had, or what it was doing in Nanhong City.

If it weren't for the latter, it would not be an ordinary danger in Nanhong City, otherwise Zhang Xuesong would not have come to send a letter to remind him.

Logically, it is unlikely that a message reminds Nanhong City that there is only a danger there, so he didn't think about going to Nanhong City before that, and Zhang Xuesong in the original time and space should not know, so it is unlikely that there is a danger there.

The more Wang Yi thought about it, the more confused he became, and he couldn't analyze what that message meant at all, so he listened to the urging of the macro detective and decided: "Stop exploring the iceberg for the time being, continue to look outside the iceberg, and pay attention to whether there are any ghosts flying out of it."

"Yes."

Wang Yi had no better way than to make such an arrangement at this time, so he sat on the seat with a headache, thinking about what other ways could he explore the situation in the iceberg.

At present, there are only thirty silent whisperers in the iceberg, and the strength seems to be a little weak.

Wang Yi thought about it for a long time and didn't think of any good plans, and planned to go outside to tell Chen Feng and them about it, and the moment he got up, the macro detective on the other end of the communication sent a message again.

The video footage shows the entrance to the interior of the iceberg, from which the Whisperers are flying out, the same Whisperers who had entered the iceberg before.

Detective said in voice that the silent ones had returned safely and were approaching them.

Wang Yi breathed a sigh of relief, and then asked Hongzhen: "Ask them what is going on inside."

Hong Detective didn't need him to ask, and soon met with those silent people, asked about the situation inside, and then relayed it to Wang Yi.

The silent whisperers who entered the iceberg all returned safely, without serious damage, and they were indeed attacked in the iceberg, which was a kind of meta-technique attack, and according to the strength of the attack, it was deduced that the attacker's combat power value was about four hundred points.

The attacker's attack was not strong, but it was so frequent that the attacked Silent Whisperers could not approach them, and they were once suppressed by that attack and could not move, so it took half a day to escape from it.

"Small attack? Frequency? Wang Yi muttered and speculated, "Yunxiao Pavilion?"

Hong Detective answered: "The investigators also detected one point, that is, the attack suffered was not a pure Yuan Technique, but a steel arrow with a length of about one meter, and the steel arrow had a Yuan Technique attack attached to it."

Wang Yi then analyzed: "Is it really the war machine of the Cloud Pavilion?"

"Probably not." Hong Zhen said.

"How?"

"If you want to say that there really is a war machine of the Celestial Pavilion inside the iceberg, or that this place is under the control of the Celestial Pavilion, then it is impossible for these ghost soldiers around the iceberg to be safe and sound until now."

"And what do you think is in there?" Wang Yi added: "New ghosts?"

"There's still too little to be found." "I suggest that we investigate the iceberg again."

Wang Yi tapped the table with his index finger while thinking, wanting to know the situation inside the iceberg, and not wanting to put the investigators in danger.

It's a pity that there is no way to get the best of both worlds at the moment, and if you want to know the situation inside, you can only take risks again, Wang Yiwei agreed to Hongzhen's suggestion.

The macro detective immediately arranged for a group of silent whisperers to carry out the reconnaissance mission again, and entered the iceberg through the original passage.

The new reconnaissance team quickly rushed towards its destination, and at the moment when it was about to reach the hollow area inside the iceberg, it was fiercely attacked, and it was difficult to continue to drive forward, so it had no choice but to retreat outside the iceberg.

Hong Zhen thought that it should be the attacker inside who noticed the passage, and began to arrange for the investigation team to re-open a new passage of entry.

Under the command of Hong Detective, the reconnaissance team quickly dug a new passage on the ice, and in less than 20 minutes, it entered the hollow area of the iceberg again, and then swooped down to the buildings in Nanhong City at great speed, and used the release of ice light arrows as illumination.

Wang Yi carefully observed the video they uploaded to the holographic screen, and saw the situation in Nanhong City more and more clearly, those buildings that seemed to be quite complete, and then saw the golden light attack again.

It didn't take long for the communication to be interrupted, and it was the communication equipment carried by the Detective Ghost Soldier who was affected.

Wang Yi had to wait for them to withdraw outside the iceberg to understand the situation, and he was not surprised or surprised by this discovery.
