The Intent of Lightning other than being a harder Intent of Heaven and Earth to comprehend than the Intent of Wind, it was also something which was more painful to comprehend.
Unlike the Intent of Wind which could be comprehended when there was wind surrounding him, the only way to comprehend the Intent of Lightning was by physically feeling it and then trying to understand it.
Unfortunately, the only way to feel lightning was by being struck by it.
And that was what the Lightning Intent Crystal did.
When a single Lightning Intent Crystal was used, it would summon lightning from the skies above and make it strike the one who was using them.
Using more Lightning Intent Crystals meant that the lightning would strike them more frequently giving them less time to rest and comprehend between the continuous lightning strikes.
As for how it felt to be struck by lightning, it was better if no one asked that.
Even to someone like Jian Shen whose cultivation had Lightning Qi in it, being struck by a real lightning was no less than a nightmare he didn't want to experience.
At the same time, the nightmare never seemed to end and kept on repeating itself because he also despite not enjoying how it felt to be struck by lightning kept on using more Lightning Intent Crystal when the ones he was using ran out.
One would think that repeatedly being struck by lightning would make one immune to it, but that wasn't the case at all.
No matter how many times lightning truck him, Jian Shen could still feel the same pain coursing through his body when lightning struck him.
Being surrounded in lightning which made his body feel like it was burning and feeling all tingly at the same time, Jian Shen could clearly feel that if it wasn't for the Lightning Qi inside his body which was protecting him, his body would've long since turned black in colour with smoke coming out of him.
Also, it took longer for Jian Shen to comprehend the Intent of Lightning than the Intent of Wind due to which he had been struck by lightning for four days straight and hadn't yet comprehended it to the maximum level possible for the current him.
...
"He brought us all here and is not going to participate in the war? What the hell does he think he is doing?"
"Regardless of what he does, we don't even have the right to question him any more. Did you forget that he entered the Dharma Realm?"
"So what? I'm also going to reach the Dharma Realm soon!"
Listening to these words, the group of female disciples from the Great Sect of Lust who were just about to walk past them stopped and looked towards the one who spoke with clear scorn in their eyes.
"Did you hear that? He dares to compare himself with our idol!"
"Fufufufufuf... He truly doesn't know the difference between Heaven and Earth."
"If even a worthless fool like you think you and Jian Shen are the same, I might as well be the stronger cultivator to ever exist."
"Look at your own face and age before comparing yourself with Jian Shen, ugly old fart!"
"Let's go girls, this uggo isn't worth our time. I'm going to climb the mountain and see Jian Shen training himself while using lightning."
"I'm coming with you!"
As the females who appeared out of nowhere cursed him and left, the two who were talking were completely silent before the one who was insulted burst into complaints.
"I'm only thirty-five years old! 35!!!"
…
"Shouldn't you be focusing on the war, Li Qiao? Why are you coming with us?"
"I'm concerned about Jian Shen's safety and want to protect him in case the lightning turns too unbearable for him."
Rolling her eyes at this answer, Yin Fan along with Yuan Wucheng and Qiao Delun flew aside Li Qiao towards the mountain.
Being those who passed the Dharma Realm, Sage Realm, and Saint Realm before finally entering the Genesis Realm, how could they not know what Jian Shen was doing after listening to him being struck by lightning.
He was obviously trying to comprehend the Intent of Lightning.
Therefore they didn't think too much and chose to wait for a day or two, after which Jian Shen would most likely come back on his own.
After all, while using Lightning Intent Crystals to summon lightning was the only proper way to comprehend the Intent of Lightning, it was a very costly method which even the Five Great Sects couldn't afford to use and train their most talented disciples.
This was because other than the Intent Crystals themselves being very costly, the Lightning Intent Crystals were among the rarest kind which made them even more costly.
And finally, there was no guarantee of how many Lightning Intent Crystals one needed to comprehend the Intent of Lightning.
Due to all of these reasons, a cultivator would normally only use a single Lightning Intent Crystal and then try to comprehend the Intent of Lightning from the lightning which struck him for a few days before using the next one, and so on.
But repeatedly using Lightning Intent Crystals, that too quite a lot at once given how many times lightning was striking the mountain, the Sect Leaders and Li Qiao could no longer hold back and decided to go see Jian Shen personally.
Arriving above the mountain, the four of them remained completely unafraid of the lightning which barely missed them and went to strike Jian Shen.
"He truly is going at it nonstop. And there are no injuries on his body either meaning that he isn't having any problem in comprehending the Intent of Lightning."
"But this can't go on forever. The war is going to start soon and I need his help in winning the war."
Revealing his intention behind coming here, Li Qiao chose to fly down and close to Jian Shen when he witnessed what those Dharma Realm soldiers had told him about.
Something that looked like a sword slash appeared out of nowhere and flew towards him.
Hastily stepping back to avoid it, Li Qiao quickly retreated with a serious look in his eyes.
"That attack just now... Could any of you defend against it?"
Shaking their heads without the slightest attempt to appear haughty and claim they could, the Sect Leaders all came to the same conclusion.
That simple and basic looking attack made using Sword Qi was done by someone a lot stronger than them.
Most likely by that False Immortal Realm Cultivator who took Jian Shen in as her disciple.
