The attacked iceberg began to emit white steam, but there were almost no pieces of ice to be found, at most a fingernail-sized slag, and no clear water had melted.

The attacks released by the Lava Ghost Soldiers are all fire attributes, with strong attack power, shattering the ice that makes up the iceberg as normal, and melting the ice is also supposed to be, but neither of these situations appears, as if attacking the hard diamond.

Detective soon realized that the attack of the lava ghost soldiers was not quite right, and it was not as smooth as the hole in the iceberg at the beginning, and immediately gave the order to the two silent whisperers next to him to attack the iceberg in front of him.

The silent whisperers who received the order quickly rushed to the iceberg in front of them, stopped about ten meters away from the iceberg, and each released a ball of water element that emitted blue light at the iceberg.

The four water element balls dragged the pale blue cold breath tail flame straight into the iceberg, and the moment they hit the iceberg, they burst out clouds of blue smoke, hitting the snowflakes covering the iceberg.

Macro, who was watching the situation, realized that something was wrong, and did not see the broken ice that should have been, and the attack point did not appear to have suffered much damage.

Detective immediately stopped the attack that the two Silent Whisperers were about to unleash, and moved forward a distance in order to see their previous attack point clearly, only to see that the attack point was indeed not much damaged, and then glanced at the lava ghost soldiers around him who were still attacking the iceberg.

The attacks of the Lava Ghost Soldiers continued, and countless fiery arrows and blood sea nebulae struck the iceberg one after another, and the light it emitted reflected the surrounding red, but it did not cause much damage to the iceberg.

Wang Yi, who was watching here through video communication, also saw that something was wrong, and asked Hong Zhen about the situation at this time in the communication.

Hong Zhen looked at the iceberg in front of him for a moment, and then said to Wang Yi: "Sir, this iceberg seems to have undergone some changes, and it is much harder than before."

"Are you sure?" Wang Yi asked.

"Sure, before we Silent Whisperers were able to easily carve a passage through the iceberg, but now we can't break the ice."

"Did you notice anything unusual about the iceberg before that?"

"Nope."

"Could it be that the place you are attacking now is hard, and the place where the passage was dug in the past is more vulnerable?" Wang Yi guessed.

Thinking that this possibility could not be ruled out, Detective ordered the two Whisperers to go to the entrance of the passage not far to the west, where they attacked the ice again.

The two Silent Whisperers hurried to the designated entrance, and it wasn't long before disappointing news arrived.

The ice inside and outside the entrance of the passage has also become too strong to destroy.

Hong Detective couldn't help but speculate that this iceberg might have been strengthened in some way, otherwise he couldn't explain the situation he was encountering now, and then stopped the attack of the lava ghost soldiers on the iceberg so that they could save Yuan Li, and then explained the arrangements he had just made to Wang Yi through the communication, and then asked, "Sir, what should we do now?" If you continue to attack, it may still have no effect, but it will make the ghost soldiers waste a lot of Yuan Force. ”

"Let me think about it."

Wang Yi, who was standing in front of the monitoring wall, walked back and forth, and played back the video footage sent by the macro detectives with the holographic screen he held in his hand, observing the attack of the lava ghost soldiers on the iceberg just now.

Wang Yi thought that it would be easier to explore the iceberg shrouded in Nanhong City, but he didn't expect that the iceberg was as strong as a defensive shield at this time.

Chen Feng, who was on the side, looked at the picture on the surveillance wall and commented: "It seems that the attackers in Nanhong City are even more difficult to deal with than we imagined."

Wang Yi stopped and said: "It's okay, what we have now is time, play slowly, I don't believe I can't find out."

"And what are you going to do next?"

Wang Yi paused the video playback on the holographic screen, closed his eyes and thought for a few seconds, and then ordered Hongzhen by means of communication: "Hongzhen, you should immediately let all the lava ghost soldiers and silent whisperers gather at you, and let them concentrate their attacks on a point on the iceberg."

"Yes."

Wang Yi then set his eyes on the monitoring wall, and operated on the monitoring wall through the holographic screen, so that it only displayed the video communication connected with the macro detective, so that the picture was magnified, and the video screen was used to view the troop movement there.

After nearly five minutes, the silencers who had gathered in one place were met through video communication, as well as the few silencers.

With the order of the macro detective, all the ghost soldiers released attacks at the iceberg in front of them at the same time, there were flaming arrows with red light, and there were also ice arrows with blue light, forming a huge cone-shaped pillar of light, hitting the iceberg directly.

The moment the attack touched the iceberg, a huge cloud of red mist erupted, consisting of white steam and fiery arrows that had not yet hit the iceberg.

The ghost soldiers' attacks didn't last, and they stopped after unleashing that attack, waiting for the red mist to dissipate.

When the red mist cleared, Wang Yi saw a crater appear on the attack point they were aiming at, with a diameter of about 3 meters and a depth of nearly two meters, and commented: "It seems that this iceberg is not yet strong enough to be perverted."

"Not bad." Chen Feng said: "It was a cluster attack of more than 2,000 ghost soldiers, but the iceberg only showed a little damage, if you clear that iceberg in this way, I'm afraid it won't be able to be cleared in a few months."

"Hmm." Wang Yi then ordered to Hongzhen: "Hongzhen, your task now is to ensure your own safety, pay attention to whether anything comes out of the iceberg, and then arrange a team of two hundred people, let them continue to attack the iceberg, and find out if there is any vulnerable place."

"Yes." Hongzhen began to arrange a new arrangement.

An assault team of two hundred lava ghost soldiers quickly moved into action, flying around the iceberg and attacking it.

Wang Yi and Chen Feng continued to discuss and analyze the attackers in Nanhong City in front of the surveillance wall, repeatedly watching the previous footage of the film.

After more than half an hour, nothing of value was found in those video footage, and the attackers in Nanhong City did not find any weak areas of the iceberg.

There are only two ways to detect the attackers in Nanhong City, one is to send ghost soldiers to enter the hollow area inside the iceberg again, and continue to search in Nanhong City, and the way to enter is through the passage dug out of the iceberg before, so it is not difficult to get to Nanhong City, but the difficult thing is how to find those attackers.

In the past, although no clues about the attackers were found in Nanhong City, only a small area in the western area of Nanhong City was searched, and it cannot be ruled out that the attackers were hiding in other places, and if the entire Nanhong City was searched, it may be possible to find the attackers.
