Looking down at her own hands, Tristana's face was filled with utter astonishment and deep curiosity.
As the Joy Factor entered her body, Tristana could clearly feel the unique liquid she had ingested continuously merging into her system. Soon after, waves of a scalding, warm current began spreading outward from her tail to every corner of her body.
It felt like a continuous, pulsing wave. A vibrant surge of life vitality continuously emerged. Tristana could vividly sense every single muscle in her body becoming more resilient, every single cell cheering and rejoicing in sheer ecstasy.
"An endless stream of power is surging out!!" Tristana stretched her body excitedly and looked at Faen:
"This is incredibly effective!"
"Of course~"
Faen flashed an 'OK' sign with his hand, then said with a smile: "Produced by Faen, absolute top quality guaranteed! But you can't slack off yet. Rest for five minutes, next up is core endurance training!"
"I don't need to rest!"
Hearing Faen's words, Tristana said with a face full of fiery fighting spirit: "The current Tristana is terrifyingly strong! I want to request that we start the training right now!"
Hearing Tristana's words, Faen rubbed his chin thoughtfully. He then stared at Tristana for a while, and after confirming that she was indeed fully prepared, he nodded in satisfaction and said:
"Excellent. It looks like you're fully prepared. Since that's the case, let's begin right now! We'll use this to test your adaptability to the Joy Factor while we're at it!"
"Yes, sir!" Tristana nodded excitedly.
Following this, Tristana quickly gathered her spirit and, under Faen's guidance, commenced the subsequent core training.
Although it sounded complicated, in reality, there was nothing particularly special about the training methods—because no matter how complex magic got, in Runeterra, even the bodies of Yordles weren't drastically different from ordinary humans in their fundamental mechanics.
Without the reinforcement of magic, the training methods didn't differ much from those in a mundane world. If there was any difference, it was simply the ability to use magic and mana to reinforce and accelerate the process and enhance the effects of the workout.
Sure enough, under Faen's guidance, Tristana lay flat on a row of low stone slabs and began performing weighted push-ups. With her hands supporting her weight against the stone surface, magic was used to drastically increase the gravity acting upon her. Ensuring the gravity wasn't concentrated on a single point, Faen used his manipulation of atmospheric moisture to distribute the immense weight evenly across every single muscle fiber of her core.
Shaped by magic, the stone slabs gave off a faint, cooling sensation. Under the buff of the Joy Factor, with every downward dip, Tristana could clearly feel the intense stretching and tearing of her abdominal muscles.
If this had been before, the current Tristana would have likely already started panting heavily, feeling overwhelmingly weighed down.
And in fact, even now, Tristana could still feel that exact same astonishing, crushing heaviness.
However, having made ample preparations this time, Tristana didn't feel nervous. Because Tristana could feel with absolute clarity that, alongside this mounting pressure, a continuous, endless stream of new power was surging from within her body.
This power erupted from the warm current converted near her tailbone, injecting directly into the muscles she was actively engaging. It constantly replenished her depleted stamina, while simultaneously repairing the muscle fibers being torn and worn down during the intense workout.
This ability to clearly feel herself growing and getting stronger made Tristana feel as if she had opened the door to a brand-new world.
Because in many cases, growth is incredibly difficult to observe and quantify. But now, for Tristana, it was as if a progress bar had appeared, allowing her to physically see her bodily capabilities being quantified in numerical values and growing steadily.
Seeing Tristana's excited expression and sensing her physical state, Faen nodded inwardly.
Yesterday, Faen had already noticed that Yordles absorbed the Joy Factor much faster than humans did.
The first time Faen noticed this was naturally with Lulu.
Back then, Lulu had just been ruthlessly fucked through her very first round by Faen. Having just lost her virginity, she was brutally turned into a cum-filled creampie, looking as pitiful as a roughly-used pocket pussy. The thick, viscous cum completely filled her womb, and under the combined effects of the Joy Factor and magic, her entire lower belly was stretched outward, bulging significantly.
This was exactly where Yordles differed from ordinary people. If it had been a normal human of the exact same size, she would have suffered a severely torn lower half at the absolute bare minimum.
But what about Lulu? Not only was she completely unaffected, but after just a brief nap, she had entirely absorbed the massive volume of thick cum inside her womb, converting it into rich, dense energy to replenish her physical body.
And during this absorption process, her body had also undergone some subtle, imperceptible growth.
Although her height hadn't changed, her physique had visibly become much more alluring and voluptuous. Her once-flat chest and her tiny flower valley below became noticeably plumper and tighter, causing Faen—who had merely had a light appetizer and was now ravenously hungry—to unleash his beastly lust all over again.
And after being fucked awake, Faen could feel that Lulu had become much more passionate. Although her movements were still a bit clumsy, compared to the very beginning—where she was almost entirely dominated by Faen, letting him pose and play with her exactly like a helpless doll—the second time around, Lulu had already learned how to actively accommodate him.
For instance, with every one of Faen's deep thrusts, she would actively arch her hips upward to meet him, allowing Faen to bury himself even deeper into her softest womb, and in turn, allowing herself to feel the most absolute, thorough ecstasy.
And by the third and fourth rounds, although Lulu's recovery speed slowed down each time, every time she woke up, she became increasingly seductive and skilled. Like a natural-born slut, she effortlessly learned exactly how to service and pleasure Faen.
If Lulu was just an isolated case and couldn't represent all Yordles, then Tristana right now undoubtedly confirmed some of Faen's theories.
Because Tristana's absorption speed was equally much faster and much more obvious than Faen had expected.
Especially during the workout, massive amounts of the Joy Factor continuously fused into Tristana's body, seeping into every single muscle fiber and every single cell, becoming an absolutely indispensable part of Tristana's body and even her mind.
Thinking this, Faen reached out his hand. With just a light flick of his broad hand, he lifted the hem of Tristana's shirt, his palm making direct contact with the waist and abdomen Tristana was currently engaging in her weighted workout.
Feeling Faen's broad, thick palm against her bare skin, Tristana's body tensed up slightly. But before Tristana could react, Faen said: "Pay attention. Keep your arms shoulder-width apart, tighten your core, and don't let your lower back sag."
