Sam looked at the large dome formation and was stunned.

He took off on the harbinger to reach a high enough altitude and activated energy vision to see what exactly is going on.

When saw some details within the formation, he couldn't help but feel surprised. The whole formation is actually being power by the valley walls in the surroundings and it didn't stop there, the formation is actually hiding many things within which cannot be seen from this far away.

He needs more information, but the small fry that Tamas caught didn't have much information, he only knew about the ice goblins, the cannons they created, the city migration due to the prophecy. As for why this exact location and what this formation is, he had no idea.

They would need to get their hands on one of the decently high-level members in the Demi-Giants family.

He turned to the Night Ghost and said.

"Can you catch one of them? I need memories of an elder-level person."

"I can, but before that, we actually need to clash with the formation once, otherwise it would be impossible to catch anyone. For some reason, I have a bad premonition about this formation. It is unlike all the formations we have seen thus far.

It is completely different. But I cannot say how."

"Why do you think I wanted to get more information? The formation is different indeed and there is a connection with the valley walls. Since we definitely know that these people know about us, this might be a tailor-made trap just for us. I don't want to go in blindly, but if there is no other way, we can only do that."

Sam spoke and went into deep thought before saying.

"Attack with varying ranged attacks. Just try and probe what the formation and those cannons are all about. Meanwhile, I will go and get on to the top of the valley walls and see what is so special about them."

"But boss, the walls are extremely high and the temperature in the surroundings is already cold, do you think you can handle it?"

"It is not a problem. I have my means. Get ready."

With that Sam immediately flew off on Sky's back. He created a thin barrier with fire element around them to defend against the cold winds, even with their power level they wouldn't be able to take the cold winds at high altitudes.

The valley walls are extremely tall, they are around a thousand meters high, essentially the valley is only a small groove in a large mountain.

Sam flew over and looked for a place to land, after finding a protrusion from the wall, he landed there and let Sky into the divine dimension instantly. He placed his arm on the wall and tried to use the observation energy.

He was stunned to see the amount of ice elemental energy inside the ice walls. It is not just pure, but extremely dense too.

If one chunk of the ice in the size of spirit stone was taken from this wall, the energy inside it would be at least ten times more than the actual ice elemental spirit stone.

He tried to pry a piece out of it, but it is highly resistant to physical attacks. He can clearly understand why the demi giants chose this place.

The remaining three sides are inaccessible for the enemies and only one side is needed to be defended properly.

He used a small energy cell and stuck it to the wall before going to the back of the sky and moving far away.

*BOOM*

Even though the explosion occurred, there is minimal damage on the wall, but he managed to get some small pieces that he could examine later.

After checking for some more time, he went back to the camp.

The team already returned and Tamas is currently performing a ritual on the dead body of a Demi-Giant. Everyone had a solemn expression.

Night Ghost immediately walked towards Sam and started the report.

"Boss, the situation is difficult than we thought, it is hard to break the formation. It has extreme ice elemental energy. We tried our best to break the formation. They really didn't know about my late-stage cultivation.

But even after we broke past the formation, the first thing that came to obstruct us is not the elder, rather they are ghosts.

We don't where these ghosts came from, but they have ice elemental energy and they are using it damn well.

The cannons of the goblins are not exactly powerful, but they will be a nuisance. We didn't manage to get deeper, we are only a few feet in and the resistance is already high, the ice attacks of the ghosts are affecting the soul too.

We only managed to kill this elder easily because, he is angry that his son died in our hands and rushed out like an idiot, we killed him and once again tried hard to break the formation and come out.

The formation healed back and they didn't pursue us. We are going to have some trouble boss. This place is not easy to deal with.

Tamas finished extracting the memories by now and transferred them to Sam.

When Sam went through them all, he is surprised once again.

It turned out that the prophet this time, not just gave them clues but also some extra tools to help them. He guided them to this valley, not just because of the defensive properties of the valley, but because the ice walls of the valley are actually ten thousand-year-old ice, completely made of pure frost essence of the highest grade.

The valley itself is a burial ground for many people who tried to get the core of the valley which is the reason for these ice walls to stand this strong for many years.

If a person manages to get that core, they could refine it to make weapons, formations, even use it for cultivation. It is a great resource, but they didn't manage to get it and died here. The souls were frozen as well.

The prophet gave some formation blueprints to the demi giants, one of the formations makes the frozen souls wake up and defend the valley, the icy dome around the valley is the result of another formation and all of these work on the ice elemental energy of the valley walls.

The number of souls in the burial ground is quite high in number. They are also of high-level cultivation. There are at least ten Late-stage Transcendent souls, and no one knows how many of them are hidden.

The Demi Giants really prepared thoroughly this time.

He explained the situation to the rest of the team and said.

"I will do some experiments; you guys throw some small liquid energy cells on the formation and see the reactions.

I need to do some experiments."

With that Sam went into the cave and took out the pieces of valley walls before trying a few things. The ice elemental energy is not that stable to begin with. It is hanging on a delicate balance and Sam tried to excite this ice elemental energy a bit to see how it would react and the results surprised him.

He couldn't help but smile.

Even though it is a bit too cold and ruthless to use this method, he really does have a proper method to deal with this situation and he would even have to pay minimum effort.

He came out, he let the team try and wrestle with that formation for the rest of the day.

When they didn't see any results by that night, Sam spoke to them.

"I have a method to deal with them. But after I am done with it, not a lot of people would survive, it would be no surprise if just the family head survives the ordeal and the rest of them all die inside. Night Ghost and Tamas, even if by any chance the family head dies, I want you to make sure that no souls escape. This family has a relation with Paras' revenge, so make sure you collect all of them."

They nodded their heads, but they don't know exactly what Sam wants to do and how he is going to do it.

"Then let's go. There is no need to wait."

"You don't need to prepare anything?"

"I have a lot of toys that I didn't test yet. I don't need any preparations, let us go. You guys wait out of the dome and I will finish it in no time."

With that, all of them left and went near the valley.

Sam once again took on Sky's back and made some rounds around the dome before hovering in a single position.

He patted on the Sky's back and said.

"It would be a bit cold. So, please do bear with it. I will cook you something good after it."

Sky nodded in acceptance and Sam smiled.

Then he took out the new machine he wanted to test.
