Krune was surprised by that. Heavin had been on the verge of completing that technique since 3 years ago. But it didn't matter how many times he tried, it seemed to always lack that final step! It continued like that until now.

"Could it be that the final link was inside those Soul Cultivation Techniques that Cinty collected this time?"

Heavin immediately nodded.

"Exactly! Thanks to Cinty, I finally found was I was lacking."

Suddenly, some kind of power spread around the room. Feifei and Krune could feel it, but they simply couldn't tell what it was. It wasn't Spiritual, Elemental Source, or even Chaos Energy. Definitely not Divine Sense either. It was completely different from anything they had ever felt before!

Suddenly, Krune and Feifei felt some kind of pressure enclose on their Souls, which immediately alarmed them! Instantly, they sent Elemental Source Energy to protect their Souls against that energy. Only then did it stop.

Krune and Feifei remembered something and immediately looked at Fie. But for some reason, she seemed to not have felt anything at all. Fie continued to eat her food, not paying attention to anything that they were talking about.

"This..."

They would need to be idiots to not understand that the one doing that was Heavin. A second later, something that looked like a blade started to form in front of Heavin. Both Krune and Feifei's Divine Sense told them that that blade was made of the same energy that was pressuring them at the moment.

Heavin shot the blade in Krune's direction without even flinching. Krune could feel the danger behind it and immediately summoned one of his Shields from his Spatial Ring in front of the blade. But then something inconceivable happened! That blade... passed right through his Shield! Krune only had the time to create a Chaos Energy barrier, which the blade slammed on.

However, his Chaos Energy barrier had little effect on the blade. It pressed forward and hit his body, leaving behind a small cut. Krune's body was sweating cold! He could tell that that that blade worked in a completely different way from the laws of the world. It could be said that they weren't even related to each other to start with!

Still, Krune didn't have time to think. That is because another blade was hidden behind the first one! As soon as the first one hit his body, the other changed direction and hit the place where his Wisp Core was. This time, there was no cut left behind. Instead, it entered his Wisp Core and went straight to Krune's Soul!

Krune once more covered his Soul with as much energy as possible. Only then did the blade got blocked. However, it was not before it pierced through at least half of the energy barrier around his Soul. Krune can count in his hands the number of times he felt to be close to death. This one has just be added to this number.

"The hell was that?"

Heavin looked at Krune's face and laughed out loud!

"Hahahaha! Did you like it? I call it Mental Energy!"

Even though Krune and Feifei were frightened, they knew that Heavin was just probing them. There was no such thing as killing intent from the very start.

"Mental energy? Is it a side effect from your Soul Cultivation Technique?"

Heavin nodded gleefully.

"Yes. This is really an unexpected gain. As I mentioned before, once my cultivation technique was complete, I would be able to start directly in the Soul Enhancement Realm. That is because my Divine Soul is already able to create Elemental Source Energy. But I never expected that my Soul Cultivation Technique would give birth to this kind of energy."

Heavin continued.

"At first, I was confused. I knew that there was something new in my Soul, but I couldn't tell what it was. However, I soon noticed that I could control this thing. Of course, the first time I ever tried to use it was when I arrived here. After all, my Soul is still inside your foundation. It seems like I have a very limited range depending on what I want to do."

Krune was quite interested in the technique.

"What else can this Mental Energy do?"

Heavin shook his head.

"My first tries were against you and Feifei. So I haven't tried anything different yet."

Krune pondered a bit before saying.

"Alright, come with me so that we can do a few tests."

Feifei and Fie seemed to be curious about it, so they tagged along.

In the end, Heavin's Mental Energy had several uses.

One of the most impressive them was obvious the low effect that the other energies had on it. Unless you put enough effort, you wouldn't be able to block it entirely. However, the Mental Energy necessary to create an attack that can penetrate someone fully prepared is enormous! Heavin could only generate three mental blades with enough strength to surpass Krune's protection before running out of energy.

Also, once those blades are condensed, they can be perceived by Divine Sense. With that, a cultivator or demon beast can prepare themselves beforehand.

Another short come is the distance that those attacks can be generated. The further away you try to create a Mental Blade, the more time you need, and it was a lot harder too. Not to mention that it also required more Mental Energy to be accomplished than one created close to you.

Another thing is that you can't create it directly inside someone's body. The Spiritual and other energies running inside would impede the congregation of Mental Energy, so it had to be done outside.

As for the Soul Pressure, it is basically Heavin releasing all his mental energy without restraint and guiding it to Krune. It doesn't need to be accumulated, but its effect is minimal as well. As long as the opponent covers his Soul with an energy barrier, the Soul Pressure would have little to no effect.

Also, Mental Energy worked well against all energies, with one exception. Luvile's Purple Tribulation Lightning! As soon as a Mental blade or any other type of Mental weapon touched the Lightning, it would be almost instantly destroyed! It was even less effective than regular attacks.

'As expected, Light Spirit's Purple Tribulation Lightning isn't that simple.'

Heavin couldn't help but complain.

"That's so unfair, is there anything that can beat this thing?"

Light Spirit snorted.

"Hmph! If you could bypass my Purple Tribulation Lightning this easy, I would have lived my entire life in vain."

Krune didn't care, though. He could think about several ways of using this power. This is something that no one expects to exist in the first place. If he hides this power with his Purple Tribulation Lighting or behind other attacks, it could give a fatal blow to an opponent, immediately changing the fight in his favor.

But there was one thing that Krune noticed that he found extremely useful.

Mental Energy could work like Divine Sense. Also, it was a lot more effective. First of all, as long as Heavin isn't targeting anyone, the other side can't feel its presence. He even called Laex over and confirmed that he couldn't feel anything. Laex's cultivation is a lot higher than Krune, so there is no way he can't feel Krune's Divine Sense. But Mental Energy was a completely different story. If Krune hadn't told him, Laex wouldn't even know that it was there at the moment.

Also, if you aren't trying to create something with Mental Energy, then you could spread it through a very long range. Although it couldn't reach the distance that the Divine Sense could, it could still go one-third of it. Of course, Krune made a comparison using the Divine Sense of an ordinary Divine Soul Realm cultivator or demon beast. But that was already impressive since it can't be detected.

'Perhaps, only someone who can use Mental Energy would be able to perceive its existence.'

Last but not least, Anti-Divine Sense Formations were useless against it! Mental Energy could pass through it as if it didn't even exist.

That was, without a doubt, one of its most significant advantages.

When everyone heard about it, they couldn't help but think.

"Heavin created something really frightening!"
