"Then we are going to enter, but not now, I need some time to check one thing."
They looked at Krune and nodded, Yusa then remembered one thing.
"Right, during that battle against the fog leopard, your Thunder Water Dragons suddenly dispersed, why was that?"
Krune nodded.
"Exactly, that's what I want to check, at that moment I felt something in my foundation that reacted to the lightning power that I used in the Myriad Water Thunder Dragons, I want some time to check why that happened."
He then looked at Shinja and asked.
"You probably know more about the situation of the Danger Zones than us, do you think that those Divine Soul demon beasts would probe this location?"
Shinja shook her head.
"Extremely unlikely, we are too deep under the ground, to probe an enormous region with Divine Sense is already somewhat difficult, to include two kilometers deep in the ground on top of that is out of question, otherwise this gate would have been found a long time ago, not to mention that the Raskie Danger Zone fog affects the Divine Sense to start with."
Krune understood the situation, then in the next second, he transformed back to his wisp form.
Shinja eyes almost popped out of her sockets, she rubbed her eyes to see if she wasn't hallucinating, but Krune was still there in the same way.
"Is that a wisp?"
Yusa put a hand on her shoulder and nodded.
"Now you know why he shows no mercy when he sees someone harming other wisps, he is basically protecting his race."
"How is that possible, shouldn't wisps be extremely weak? His combat prowess is out of the charts too, he far surpasses the strength of those with the same cultivation."
Yusa turned to Krune and asked.
"I will explain to her about your past, do you think it is okay to talk about that?"
Krune agreed.
"Go ahead, I will have to concentrate for a while, so leave some space for me here, explain to her about everything, the Myriad Energies Technique is okay too."
Yusa nodded and left with Shinja, she was going to explain about Krune's power, she then took a blood contract and started writing on it.
"Shinja, this is not because we don't trust you, in fact, I might tell you this straight away, Krune is a wisp that will never force anyone he trust into a blood contract, this is something that me and Ao insisted, the reason being because not only will you not be able to talk about it without Krune's agreement, but also because it won't allow those memories to be forcefully read like with Soul Searches that high level cultivators can do."
Shinja then looked at Ao Sulian, who nodded, she then took a deep breath and signed it, Krune has already shown his wisp form before she signed anything, if she wanted she could simply refuse and no one here would be able to do a thing, they are still not her match, but even so, Krune still trusted her and showed his true form, that's enough.
"Can you tell me now how a wisp was able to get to this point?"
Yusa and Ao nodded and started talking about everything.

On the other side of the cave, Krune was paying attention in his rainbow core, he started to summon a little of lightning elemental energy outside, at first, nothing happened, what made him a little puzzled, but then he decided to straightly use the Thunder Line skill, as expected, his rainbow core rippled again and his control over the skill went out of control, some sparks flew around and the skill disappeared.
'As I thought, it's the lightning elemental energy that causes it, the moment I use lightning power, the lightning element inside my rainbow core reacts to it, if I'm not wrong, it is because the rainbow cores lightning came from the Heavenly Tribulation, could it be that it has some conscience of its own?'
But that was not the issue, the issue was that he couldn't use lightning power because of that, he tried several times but had no use, as long as a large amount of lightning elemental energy was used, his rainbow core lightning would mess up with it. It was then that Krune had an idea.
'Could it be that my rainbow core wants to eat the lightning that I'm using?'
He thought it to be very likely, otherwise, why would it intervene only when a lot of elemental power was used? That's probably because it only cares if there is a lot.
Krune then directly summoned lightning energy around of the rainbow core, and sure enough, it started absorbing the power of lightning, but that wasn't all, he could feel that the power of lightning that he fed to his rainbow core was being converted into the power of tribulation lightning as well. It was then that a crazy idea came into mind.
'If there is a lot of tribulation lightning elemental power, can I use it by myself?'
He didn't know if it was feasible, first of all, he had never heard about someone having the tribulation lightning as part of their cores, let alone using it.
'But if it works, the power of my lightning skills will multiply several times, it will definitely become my best trump card!'
Krune kept feeding lightning power to his core, the process was quite slow, not to mention that it used a lot of spiritual energy, the problem was that only 5% more or less of the lightning element power that he sent in was converted into tribulation lighting, the rest was simply discarded by his rainbow core, but he understood the reason.
'The tribulation lightning of my rainbow core is basically filtering all the impurities in my own lightning power, in the end, only 5% is usable, but this is good, it shows how powerful this lightning is really is.'
Time passed, Krune had to stop to recover his spiritual energy three times, and only after 10 hours did his rainbow core finally stop absorbing lightning element.
'First, instead of trying to use the tribulation lightning, let's try to use a normal Thunder Line, I want to see if my rainbow core tribulation lightning will intervene now.'
Krune summoned lightning power and used the skill, the Thunder Line pierced the cave wall and disappeared deep inside.
'As expected, if my rainbow core tribulation lightning is satisfied, it won't mess around with my normal control over the lighting element, even if I can't use the power of the tribulation lightning, I still found a way to stop it from affecting my own lightning element. The problem is, how should I try to use it?'
Krune pondered a bit and tried to guide the tribulation lightning just like he guides his spiritual energy, but it didn't even move, he tried to bait the lightning out using his own lightning power as a bridge but no success either, in fact, there wasn't much Krune do anyway, it was then that he thought about something.
'My Spiritual Energy Meridians when they were being formed were capable of absorbing and let the tribulation lightning pass through to get inside my universe foundation, can I do the opposite?'
Krune had never thought about doing the reverse option, but he thought it was worth a try, instead of connecting all his seven meridians with his universe foundation, he took one out and connected directly with his rainbow core, but nothing happened at first.
'I see, that's because I used my meridians to absorb, I have to reverse the flux, instead of absorbing things from outside, I will absorb things from the inside.'
As expected, when the flux of the spiritual energy meridians was changed, it started to absorb the tribulation energy from the rainbow core, he only absorbed a little bit to the outside and the fused it's power with his own lightning element before using another Thunder Line.
Krune was impressed, the size of this Thunder Line increased by three times, it was obviously much more powerful. He then threw it against the cave wall, as expected, it also pierced through the wall and went deep inside, the hole left behind was much bigger than the previous one too. Krune used his Divine Sense to probe the distance it that it traveled before dissipating, it wasn't before it got a hundred meters away that it lost of the power.
'Impressive! The normal Thunder Line was only able to pierce twenty some meters inside, but with just this little bit of tribulation lightning its power increased several times!'
Don't look down on the distance that the lightning went through the wall, lightning energy is weak against the earth in the very first place, for it to go all the way to a hundred meters is already a very scaring power.
Krune got excited, he wanted to try more, he returned to his human form and went to talk with Yusa and the others, he explained what he found and that he wanted to use it outside.
'It is also a test to see how much tribulation lightning I can summon at once, my rainbow core definitely won't allow me to use everything, so I need to know my limit.'
Yusa and the others nodded, if they are venturing together inside the secret realm, they must know their group members full capabilities, only like that their coordination can reach its peak.
Krune's group left the cave and covered its entrance, after that they moved far away from there, if Krune's tribulation lightning is really that powerful, then he might attract a lot of attention after using it.
Krune asked Shinjas to help with a 9th stage Foundation Establishment demon beast, after looking for one during an hour, Krune's Divine Sense finally spotted one, It was a Crimson Tiger, and it was at the peak of the 9th stage at that.
Krune told Shinja to be ready to help in case things go south and went forward to confront the beast, Tigers are lonely by nature, this one was no different, thanks to that Krune didn't have to bait one out of a group and went directly to attack.
When the Crimson Tiger saw Krune is was surprised.
"To think that a 4th stage weakling would come this far inside the Danger Zone, I guess this is my luck day."
Krune smiled after hearing that.
"Is that so?"
The tiger was taken aback with that answer, its instincts told it that something was fishy, it used its Divine Sense but only Krune appeared in it. Shinja stayed far behind exactly to prevent the tiger to notice her presence, Krune told her that if it doesn't work, he has the confidence to hold long enough for her to arrive.
After the tiger found nothing it didn't wait anymore, the feeling that something bad was going to happen was still bothering it, so it attacked straight away to not give a chance for anything to happen.
Krune saw it moving straight at him, it would be in front of him in a second, but he was calm.
'An attack that can use the total power of the lightning tribulation available to me, there is only one thing that powerful in my book.'
Krune concentrated his entire mind in the attack, his spiritual energy meridian absorbed tribulation lightning like crazy until its connection with the rainbow core was cut off by the core itself, Krune then concentrated the entire power of the lightning high above him.
"Heavens Fall!"
That's was that only thing he could think of, the attack that had given the greatest impression ever since he was born, the lightning strikes of the Heavenly Tribulation! Only that would be able to display the full might of the tribulation lightning.
The Crimson Tiger was alarmed! That strike came too fast, it had absolutely no time to even think about a counter measure when it hit its back.
Boom!
An enormous explosion blasted the everything away, even Krune who was the owner of the attack was blasted in the distance, only able to stop himself after two hundred meters! The fog around was cleared up to five kilometers away, it even revealed Shinja and the others in the distance, they looked at that apocalyptic scene in front of them, seeing that made Shinja and the others sweat rivers.
"That's not the power a Foundation Establishment should have, even an early stage Core Formation cultivator would probably die if hit head on with such attack."
When Krune looked at where the Crimson Tiger was, there was only a crater left behind with lightning sparks appearing everywhere, the tiger was nowhere to be seen, it had been completely pulverized, not even its demon core was left behind, Krune looked at that scene with apprehension, the power of the tribulation lightning was too absurd! But he quickly came back to himself, this explosion will definitely attract the attention of the nearby demon beasts, they need to leave!
---
Back in the gate cave, Yusa and the others were looking at Krune as if he was a monster, all that attention made him feel quite uncomfortable.
Shinja then asked him.
"How did you keep the tribulation lightning with you? I also underwent the tribulation when I reached the foundation stage with my Universe Foundation, but I had to give my all just to fend it off, let alone keep it, not to mention that I had the help of the guild back then, otherwise I would have definitely died."
Krune then explained that he used his spiritual energy meridians to guide it inside and then divided it in several parts before guiding it to hit his planet, then he told what happened after the tribulation was over and how the remnant power of the tribulation lightning struck his rainbow core while it was being formed by the power of the world.
Shinja and the others were amazed, in the end it was just a coincidence that something like that happened, but Shinja understood better, there is no way someone would purposely strike their future core after being successful in building a Universe Foundation, it would be just seen as suicide.
Ao couldn't help but comment.
"Anyway, that strike was too powerful, that peak 9th stage Foundation Establishment Crimson Tiger was turned into dust, this is incredible!"
The other looked at him with jealously, if by drinking his blood they could gain that power, they would definitely suck him dry!
Krune looked away and pretended it wasn't much.
"I just used a little bit too much strength, that's all."
The others mouth twitched.
Just a little bit? Is he making fun of us? If that is just a little bit then what about us? Can you first think about our sentiments?
Yusa smiled and gave them an idea.
"What if we cut him into pieces, then we fry and eat a little? Perhaps some of that power can be used."
Shinja and Ao eyes lit up, they immediately nodded.
"Seems like an amazing idea!"
And just like that, Krune received a three sides beating, he wanted to cry but had no tears.
