Truth to be told, the sound Isaac heard before seemed to be a combination of both static and inaudible but at the same time, through Isaac, understandable via certain circumstances.
The calling felt like it was asking him to come. Not in a demanding or provoking way, but honestly and politely.
And yes, the thing that is trying to communicate with Isaac is not speaking with words but feels more like a... spiritual connection.
This led to Isaac thinking that it might be another Cryo creature. But this was a far stretch. After all, when he met the Cryo Whopperflower, he did not feel anything like a connection to it. He only commands it and the Cryo Whopperflower will follow. No spiritual connections were made to instruct it.
Another one of his guests was that it is some sort of creature that is buried in the icy mountain that is trying to reach out to him. Due to Isaac's skepticism, curiosity was born in his mind and he finally decided to go to the location where the signal of the creature trying to communicate with him is.
'I just hope that this is not some kind of trap...' Isaac thought as he crossed a ravine with ice beneath his feet
This wariness of him is a natural trait he had even before coming to this strange world. And with his transmigration, it just got enhanced further to survive in this unknown world he got sent to.
While walking, the signal that was being sent to him was growing stronger. With each step he made, it was as if the calling's loudness was increasing.
This, of course, greatly annoyed Isaac as he can't put his mind straight.
He then made a sigh and looked at the huge opening at the bottom of the ravine he was walking on.
In his right view, down below, a huge open area was present. It had some ruins and some obvious signs of a civilization previously living there.
'Odd... Now that I've thought about it, this mountain has a lot of ruins on it...' Isaac thought as he remembered all the ruins that he came across. 'Did something happen to the people living on this mountain that caused their... disappearances?'
Isaac then suspiciously looked at the mountain's summit and silently hummed. 'Does it have something to do with that giant pillar...?'
Isaac has been skeptical of the giant pillar on top of the mountain ever since he first saw it. He knows that it's playing an important role in the mountain, but he just doesn't know why. But now, he was starting to place some clues and connect them. 'Perhaps that giant pillar really is the main perpetrator of all of this...'
After having that thought, Isaac once again sighed before continuing his walk. 'For now, that's just my theory. If I want to learn more, I have to investigate this whole mountain to learn more...'
'And also to dispose of that pillar.' He gave a sharp glance at the summit one last time before increasing his pace of walking.

Meanwhile, at the camp where the survivors are, Parsifal looked at the giant boar resting at the sides. As for the other two survivors, they were still unconscious due to the amount of blood they lost.
Parsifal's staring was quite sharp. For even Moccus found it uncomfortable. So, he decided to ask him. "What's wrong, young one?"
Parsifal heard Moccus' voice and instantly stopped staring at him and replied while stuttering. "I-It's nothing. I-I was wondering what type of creature you are...?"
"I am the King of the Snow Boars. Mine kind used to live up in the north, making us adept at icy temperatures. But due to various circumstances, mine ancestors were forced to migrate here." Moccus explained.
"I-I see..." Parsifal nodded in amazement as he had just learned something new. He then looked at where Isaac walked to and asked with curiosity. "Di-Did what Sir Isaac said true? Sal Vindagnyr... Can't affect him?"
Parsifal was a naturally curious child. As a noble, he had been given the best education. And on one frightful night, he stumbled upon his clan's history and saw the heroic feet his ancestors did to bring justice to Old Mondstadt. Because of this, he decided that he would be just like his ancestors. Brave and powerful but delivers justice to those who threaten the safety of the people.
And with the corruption that is currently breeding and multiplying in Mondstadt, he found it the right time to become like his ancestors.
But because he was just a mere child, he could only accomplish a few things. That's why he decided to quickly learn as much as he can and train under a knight so he can be strong in the future to deliver his justice.
And now, having just witnessed a man take on the cold temperatures of Sal Vindagnyr with no proper equipment saying that he has no problems with it, Parsifal naturally wanted to know more.
Moccus made a low hum before answering. "Indeed. Sir Isaac is... Well, he's unique. He insists that he's a human but I believe— actually, nevermind."
Moccus originally wanted to tell Parsifal the abilities of Isaac like how he is immune to coldness, perfect control over the cryo element even without a vision, and finally, the ability to command cryo-type creatures.
But in the end, he just sighed and decided to not tell him and to not expose some of Isaac's abilities, of course. Furthermore, he wasn't even sure if that's all the abilities Isaac had. Who knows? Perhaps one day, Isaac will suddenly create living cryo creatures from pure ice out of a whim.
Parsifal was intently listening to Moccus with great interest but he was disappointed as to why Moccus would stop walking. "Are Sir Isaac's abilities... A secret?"
Moccus chuckled and replied with an amused tone. "If thou think of that way, then thy correct, young one."
Parsifal nodded with a smile and decided to not pursue Isaac's secrets anymore.
Moccus, however, suddenly looked at where Isaac left. He then stood up with his massive body and looked at the distance where Isaac may be.
'The elemental energy there is... Rapidly rising...?' Moccus thought in all the seriousness.
He somewhat knows that Isaac is currently where he sensed the sudden rising of Elemental Energy, so he got slightly worried. 'Is Isaac fighting a creature there? Or something else? Hmm...'
Having thought of that, he looked behind to Parsifal and said seriously: "Stay here, young one. I'll be back."
Without waiting for Parsifal to reply, Moccus left to find Isaac. As the King of the Snow Boars, he naturally had a thick hide to keep his body warm, albeit this will only last for at least 30 minutes before he gets frost bites. That's why needs to find Isaac immediately.
Without wasting any more time, he departed, leaving the dumbfounded Parsifal on the camp.

Moccus ran through the icy blizzard in front of him with ease. This is because some of the unstable paths he walked past to has been inlaid with a new clear ice path, obviously made by Isaac. This made his traveling easier as he just needs to follow the icy path to find Isaac.
Not to mention that the ice paths and bridges Isaac made were extremely strong, making it easier for his massive body to move and not break them.
After following Isaac's ice path for a solid seventeen minutes, Moccus finally arrived where Isaac was.
It was an open circular area with what looked like an arena in the middle. The area was isolated from the rest of the mountain with only one entrance leading to it where Isaac made an ice path.
Moccus arrived and breathed heavily for a few moments before seeing the thing in front of Isaac.
His eyes slightly contracted as if he couldn't believe what he was saying. Then, a silent chuckle was made by Moccus. "Haha... So you can even do this, huh? Sir Isaac..."
Currently, in the middle of the arena, Isaac was standing with some debris and dust scattered on his clothes. Though, despite the dust on his clothes, his face and body did not seem to be harmed. Moreover, he looked more fine than ever!
"Glad to welcome you to the team..." Isaac silently muttered to the creature in front of him with seriousness as he sharply looked at it.
"Daleth."
In front of Isaac was a levitating cubical creature that seem to be submitting to Isaac.
It was a cryo hypostasis. An elemental creature made with the purest elemental energy of the Cryo Element.
