Cain''s body shook with an uncontroble intensity. Beads of sweat continuously polled down his forehead, dripping onto his uniform, rapidly drenching them.


    The power he was currently holding wasn''t easy to maintain at all.


    Excitement was stered onto Cain''s face even as he was still in his most concentrated state.


    With this power, he felt like he could ruin a 9th level Nascent Formation cultivation in a single trike!


    That would be a level of prowess surmounting three levels!


    This is the separation between Mortal and God Gxy cultivation methods. With one Martial Skill, Cain has a trump card most cultivators in the Lower Realm can only hope to achieve.


    ''I wonder….just how many of my siblings managed to achieve this stage so early? And thinking about it, is Kali doing this right now? Her Skill should be equally as-''


    Suddenly, Cain''s thoughts copsed in on themselves.


    All at once, he was hit with an immense wave of exhaustion. His body trembled, nearly wanting to m right on the ground.


    In this instance, Cain struggled to keep his stamina. His eyes zed with ferocious determination. He wanted to keep this Martial Skill for as long as he could.


    In battle, a powerful move like this needed to be used instantly andst for that duration.


    There''s no way he should be hit with a wave of exhaustion so quickly; Cain couldn''t ept this!


    However, no matter how determined Cain''s mentality was, his energy reserve spoke a different story.


    Merely five seconds passed since Cain formed his Dragon Lightning w. And already, his Qi energy reserve drained to 10%. With such low energy reserved, his bodily stamina naturally couldn''t keep up.


    Without Qi energy flowing throughout the entire body, a cultivator''s stamina is severely limited.


    Under normal circumstances, Cain would''ve dropped to the ground by now. But there was one critical factor that kept Cain up for so long.


    The Astral Energy seeped within his bones!


    Cain''s physical body has been continually strengthened beyond any Nascent Formation realm cultivators. So naturally, his bodily stamina was enhanced to a great degree.


    To achieve this level of time was far impressive enough. His own grandmother would be particrly shocked seeing Cain''s level of endurance.


    With each passing second, Cain could feel his control rapidly improve.


    However, even with enchantment, Cain''s endurance couldn''t contain the might of the Dragon Lightning w for long.


    ''Chi!''


    The wind loudly whistled as Cain''s Draconic Lightning Aura and Dragon Lightning w dispersed into tiny Lightning wisps of energy.


    "Fuu~."


    Cain exhaled a long sigh of all his previous tension and concentration. He felt wobbly, his eyes were blurry, and the world felt like it was spinning around him.


    Right then, Cain was about to drop to his knees. The exhaustion was nearly too much to handle.


    But at that moment, Cain''s Soul core pulsated. His Soul and Heart direct link unleashed a refreshing sensation straight to his mind.


    As the refreshing sensation engulfed Cain''s mind, he suddenly snapped his body straight up. His eyes quickly regained rity, and the world gradually stopped spinning around him.


    Cain was still incredibly exhausted. But a weary yet pleased smile graced his lips.


    "I get it! The Martial Heart is a way for any cultivator to bounce back after any period of extensive training. If I were to justy down right here, the benefits of the training session would be lower than if I were to stay awake!" Cain''s eyes shed a radiant brilliance.


    Indeed, he could detect that his perception over Draconinc Lightning energy slowly improved at this very moment.


    Now that he wasn''t focusing all in on controlling a tremendous bundle of energy, his mind perception can slowly digest the previous sensation he was experiencing.


    If he were to fall asleep now, those sensations wouldn''t be as vivid as they are now.


    This process was half mentally draining and half enlightening for Cain. If his own Will wasn''t as forged as it is now, most of his progress would''ve significantly diminished.


    As Cain gradually digested his new perceptions gains, he began to critically analyze his mind. ''It took almost an hour to first form the Dragon Lightning w. But now that I know how to do it and have broken past the formation border, I''ll be able to majorly cut the time. Before tomorrow, I''ll train to at least make it into seconds. Now let''s see….while I wait for my reserve toe back to full, I''ll start practicing with Spirit Energy and itsbination.''


    Since this was just training, Cain wasn''t so hasty to waste his Pills to instantly regain his Qi energy reserves.


    But this rest period can give him time to crush two birds in one stone. Cultivating spirit Energy on its own andbining it with Qi energy.


    Both of these abilities are another trump card of his when he and Kali go out for a mission tomorrow.


    Cain didn''t have to worry about ruining his Draconic Lightning perception gain as it would passively grow on its own as long as he''s awake.


    Then, without a second to waste, Cain sat into his cultivation state and called upon his Spirit Essence Core.


    ….


    The night quickly flew by, and soon enough, the next day arrived.


    Bright sunlight shined throughout the entire special Ranking-students field. The radiance of pure sunlight created a magical scene that seemed like this ce waspletely peaceful.


    At this moment, Cain was still inside his training room. He sat meditating, perceiving everything he got done during the short night.


    Cain didn''t sleep at allst night. But he wasn''t bogged down with weariness at all.


    Before the sun arose, he calcted going into a cultivation state to gain back all of his energy at once.


    Cultivating isn''t precisely the same as getting a good night''s rest. One is still using a lot of function from the brain to eitherprehend Qi energy or perceive whatever technique they''re currently cultivating.


    But it was rxing enough for any cultivator to gradually gain back their energy.


    As the morning came, Cain remained still in his cultivation state. It wasn''t until his Spirit Sense detected a presenceing over that he prepared himself to get up for the day.


    Then, mere momentster, Cain heard a knock at the front day.


    ''Really. Doing this stuff only feels like a couple of hours passed by. No wonder these guys have such long years.'' Cain internally mused to himself as he flung his eyes wide open.


    In that instance, only for the briefest of seconds, a spark of Draconic Lightning energy shed within his pupils.


    This was the sign of the new pure power Cain diligently cultivated allst night.


    As his eyes returned back to normal, Cain slowly stood up. He let himself experience every crackle of energy his joints caused while stretching his body.


    In this process, Cain could directly feel how much he had grown fromst night. And at that moment, his mind was determinedly made up.


    The time for doing missions was right upon him and Kali!


    With his blood eagerly pumping up, Cain swiftly strolled over to the front of his door and opened it up.


    Of course, standing right in front of him with an equally gleeful expression was his dear sister Kali.


    "Are you all ready to go, Cain? I''ve been thinking about today all throughout myte-night training." Kali''s tone was simply full of pure eagerness.


    A colder aura emitted out of her as she couldn''t suppress the excitement of strolling out into a dangerous zone.


    This colder aura immediately pricked Cain''s interest. His eyebrows furrowed as he swept his Spirit Sense over Kali.


    On the surface, Kali''s cultivation didn''t advance. But he could perceive that her strength greatly enhanced after just one-night training.


    A smirk curved up Cain''s lips as he first asked, "Of course I''m ready to go. But I''m curious, Kali. Just what training did you dost night? As you could probably tell, I trained with my manual Martial Skills and Spirit Energy. So just how far did youe along?"


    "Hehe~!" Kali sweetly giggled. "If you can do it, then I sure can do it too, brother! I as well managed to take my first step inpleting my Ice Dragon w, and I made some progress with Spirit Energy. This should be enough for a more harder mission, right?"


    Cain took a small moment to think about where theirbat prowess would lie with the various missions offered to them.


    All throughoutst night, he made some rough estimate on their overallbat prowess based on what he experienced.


    Currently, if Cain were to use his Draconic Lightning Aura, he could match even a peak 8th level Nascent Formation cultivator. If he used Spirit Energy within his attacks, he could directly contend with an average 9th level Nascent Formation cultivator.


    Out of everything, Cain''s expectation for his Dragon Lightning w skill was massively high.


    He believes if hebines it with Spirit Energy, he could probably severely injure a weak Early Stage Profound Soul warrior if they were entirely off-guard!


    Although, that would only be ast resort.


    That move would undoubtedly expend all of his energies in an instant, leaving himpletely helpless afterward.


    As for Kali, Cain had a rough estimate she was around 7th or perhaps 8th level if she used all of her energy. She was always just a little bitckingpared to him. But nevertheless, monstrously powerful in her own right.


    Considering all of this, Cain felt they were ready to test themselves once again. "With our current level, we can take on a difficult mission. Come, let''s discuss our limits while walking up to meet up with her."


    After saying so, Cain and Kali began strolling out into the sunny field.
