The others nearby were also looking in that direction.
However, it was clear that they had obtained no information other than the Calamity Beast on the surface.
Even the surface Calamity Beast, because of the distance, could only be roughly seen in numbers, only a few at most.
"No, what are the Calamity Beast doing underground? Are they a race living underground?" Zhou Xuan looked over with some doubt.
"Perhaps it's the kingdom of some Calamity Beast that lives underground." Wang Hu crossed his arms and looked in that direction.
"A kingdom?" Zhou Xuan looked at Wang Hu with some doubt.
"We gathered the surrounding Calamity Beast together simply by relying on our strength," Wang Hu said simply.
"Uh, this... would such a thing happen in the Erosion Zone?" Zhou Xuan asked, somewhat skeptical.
"If they were summoned in, this situation probably wouldn't occur. But what if they were already in this area, and were directly brought here due to the overlap of the two worlds?" Wang Hu said in a deep voice.
Zhou Xuan pondered for a moment, then slowly nodded.
Hmm... that seems to make some sense!
Having said that, he turned to look at the crowd.
"But how do we explore underground? In the past, we had Qin Yu try to blend us into the surrounding environment and see if we could crawl in?"
Qin Yu opened her mouth slightly upon hearing this, "If we don't have a 5th Tier Calamity Beast, we can still try, but..."
She didn't say anything more, but everyone understood what she wanted to say.
They couldn't be sure if there were any Fifth Tier Calamity Beast underground. If there weren't, that would be fine, but if there were, and they encountered one, then they would probably truly have nowhere to go underground.
Wang Hu frowned as he gazed at the distant scene, pondering if there was any way to resolve the situation.
Although Zhou Xuan didn't speak, he also frowned.
Shen Heng withdrew his gaze, glanced at the two who were frowning in thought, and said:
"I don't need that method, I can just sense it directly."
Upon hearing this, Zhou Xuan looked over with some confusion.
"Hmm? How do you plan to sense it? If you could hear it, wouldn't you have been able to hear it from your current position a long time ago?"
" Sound Wave Imaging can detect the specific situation in the surrounding area," Shen Heng said simply.
"Um?"
Zhou Xuan was slightly taken aback, and Wang Hu and Qin Yu also subconsciously looked over.
" Sound Wave Imaging? Sound waves? When did you learn this? I don't remember seeing you use it during the training camp." Zhou Xuan looked at Shen Heng with some doubt.
"It will only happen at the end of the training camp," Shen Heng said simply.
Why didn't you use it before?
"Compared to hearing, the range of perception is much smaller, only within 15 kilometers, so the previous methods were useless."
After giving a brief introduction, Shen Heng let out a soft breath and turned his attention back to the present.
He glanced at the place where the Calamity Beast had gathered, then slowly closed his eyes.
Using his Origin Power, Shen Heng silenced the surrounding sounds.
The sound waves began to rise rapidly, stopped at a specific frequency, and then spread outwards.
The invisible sound waves rippled towards the hills in the basin, vibrating slightly upon contact with matter before echoing back...
But even more sound waves pierced the ground.
More and more sound waves were transmitted back, Shen Heng began to quickly analyze them.
A black-and-white image began to rapidly form in his mind.
Beneath their feet lay the mountainside, the basin that had expanded outwards, the rolling hills, and the passage that stretched downwards...
Silence fell on the mountaintop as everyone waited.
Wang Hu looked at the Calamity Beast on the distant ground, then suddenly turned his gaze to Shen Heng.
Hearing, sound waves—no wonder the base assigned him to be the first to carry out this kind of mission...
Turning his gaze back, Wang Hu looked once more at the distant hills.
Beside her, Qin Yu slightly withdrew her gaze.
"It is a bit..."
On the other side, Shen Heng sensed the world beneath the earth.
The thick channels, like blood vessels, spread and extended underground.
Many of these areas are very open, resembling the internal organs of a body.
One after another, Calamity Beast roamed the underground world.
Shen Heng's consciousness followed the passage downwards.
Along the way, it paused on Calamity Beast that was sleeping soundly in a large area, then swept over more than ten other Calamity Beast that were scattered in various places and were also quite large, and finally stopped in a very open area.
In this area, a large number of Calamity Beast roam.
They might be waiting somewhere, carrying something, or dumping something somewhere...
There was also a Fourth Tier Calamity Beast sitting on the side.
This is...
Shen Heng slowly opened his eyes.
Zhou Xuan, who had been keeping a close eye on Shen Heng's situation, asked:
"How's it going?"
Upon hearing this, the others also looked over.
Shen Heng's gaze drifted slightly to the distant hills.
"It's larger than I imagined, extending more than a thousand meters underground, and its area is approximately three kilometers."
"Hiss--, it's so big!" Zhou Xuan gasped.
The others also silently frowned.
"Are there any Fifth Tier or Sixth Tier Calamity Beast?" Han Ling asked.
"There are no Sixth Tier, but there is one Fifth Tier beast, thirteen Fourth Tier beasts, and the rest are ordinary low-tier Calamity Beast," Shen Heng said calmly.
Zhou Xuan breathed a sigh of relief, but soon realized that it seemed unnecessary, since what they had just discussed was beyond their capabilities.
"So what? What are they doing down there? Like Wang Hu just said, is it a kingdom where everyone lives their own life?" Zhou Xuan asked.
The others beside him were also watching Shen Heng, and they were equally curious about the question.
" The Calamity Beast seems to be..."
Shen Heng paused for a moment before continuing:
"Collect resources."
"Gather resources?" Zhou Xuan repeated subconsciously.
Wang Hu frowned deeply.
"Yes, gather resources." Shen Heng repeated himself, this time with much more conviction.
He suddenly understood why, when the Erosion Zone appeared, it always took many days before the Calamity Beast would emerge from Erosion Zone and reach Blue Star.
Perhaps, it's not just about mobilizing the Calamity Beast; it's also about identifying which resources have been transferred to the Erosion Zone and arranging for the Calamity Beast to continue gathering them.
"What resources?" Zhou Xuan asked.
I don't know.
Shen Heng shook his head slightly.
He truly didn't know; let alone the fact that images could only depict shapes, he probably wouldn't recognize them even if they were colorful.
After all, it's not even worth mentioning whether this material has ever appeared on Blue Star.
Even if they did appear, by the time they reached him, they were all finished products with a different appearance.
"So, the previous Calamity Beast were also like this, gathering resources there?" Wang Hu said in a deep voice, arms crossed.
"It's possible, but not certain. We'll have to explore further to find out the specifics," Shen Heng said calmly.
Wang Hu nodded slightly. "So, what's next?"
Shen Heng was about to say that now that they had investigated the situation thoroughly, they should prepare to evacuate.
But the words vanished before they could be uttered.
He slightly raised his eyes, his gaze fixed intently on that area.
Sensing something, the Calamity Beast that had been overseeing the work stood up, as if something had been completed...
