[Dual Cultivation System Usage Rules]

1.  Talent Replication: After the exchange of bodily fluids with a person possessing a specific talent, one talent can be copied from them.
2.  Skill Replication: Only after successfully replicating a person’s talent can one continue to copy their skills through the exchange of bodily fluids.
3.  Random Draw: If the target has multiple talents and skills, a random one will be chosen for replication during each exchange of bodily fluids. (Note: The stronger the talent or skill, the lower the probability of randomly drawing it.)
4.  Requirement for Talent Replication: Successful replication of a talent requires the deepest exchange of bodily fluids. (Note: The exchange of fluids is only the beginning.)
5.  Talent Absorption: Similar talents can be absorbed and merged. (Note: To refine and consolidate.)

After reading all the information, Caleb’s eyes lit up. Not only was the activation method of his cheat unique, but the cheat itself was perfect for this world.

This was the correct way to open the door to the underworld, it seemed.

Snapping back to reality, Caleb subconsciously began to thrust his hips in cooperation. After a brief period of adaptation, Yukina Sasaki also gradually increased the speed of her movements.

Working in sync, in less than ten minutes, the inexperienced Yukina was utterly defeated. Her flushed, delicate body collapsed onto Caleb, followed by a fierce squeezing sensation from “little Caleb.”

Caleb trembled, a shock running through him. He, too, could no longer hold back and climaxed with her.

A ‘ding’ sound echoed in Caleb’s mind again.

[Ding! Replication Successful!]

[Acquired Talent: Physical Vitality.]

[Talent Description: Significantly enhances physical constitution and recovery speed.]

Caleb had only felt he was getting stronger and that his stamina was seemingly endless. After the talent was successfully replicated, a power several times stronger than before instantly filled his body. His previously soft “little Caleb” also rose up to full attention once more.

So, the so-called deepest exchange of bodily fluids meant deep penetration…

Understanding the condition for successful replication, Caleb exerted force with his limbs, snapping the low-quality restraints.

To the astonishment of Reina Hamada and Ruri Kurumizaka, he reversed the situation, pushing them down beneath him.

“Reina, I told you if you let me be proactive, I wouldn’t run.”

“Mmm… Oh…”

As “little Caleb” breached her gates, Reina’s eyes misted over, and she let out a muffled whimper.

[Ding! Detected Talent: Eye of Insight.]

[Commencing Replication…]

Fifteen minutes later, the talent was successfully replicated.

“Uesugi, hurry up! Ruri can’t wait anymore!”

Having watched two rounds, Ruri had long been impatient. Seeing “little Caleb” reappear, she immediately swooped down, not caring that he was still coated in her friend’s fluids.

Thanks to the Physical Vitality talent, “little Caleb” quickly regained its fighting form.

To the expectant gaze of the silver-haired, twin-tailed, big-breasted beauty, Caleb achieved a third round.

[Ding! Detected Talent: Mental Resistance.]

[Commencing Replication…]

Twenty minutes later, Caleb obtained his third talent.

Setting down the soft body in his arms, Caleb couldn’t help but let his mind wander.

Using this ability was truly a test of stamina. If his first talent hadn’t been Physical Vitality, he might not have been able to fight three consecutive rounds. Moreover, the better his endurance, the longer it would take to successfully replicate a talent… He wondered if he could still successfully replicate a talent by just cumming without the other person climaxing.

Next, Caleb focused his attention on the Eye of Insight and Mental Resistance he had just acquired. He had been too focused on getting more talents to check their effects.

(It definitely wasn’t because Caleb had gotten a taste for it and was impatiently eager for two more rounds.)

[Eye of Insight: Enhanced vision. Focusing concentration allows for the observation of special energy.]

[Mental Resistance: Immunizes against or reduces the influence of mental-based abilities.]

Simple and easy-to-understand abilities. Although they didn’t seem flashy, they were actually very practical. Caleb tried taking off his black-rimmed glasses. After a slight moment of dizziness, his vision remained as clear as usual.

It worked! Not only had his body become stronger, but his nearsightedness was completely cured!

Excited, Caleb squeezed the soft flesh in his hands, causing Reina to frown slightly.

“I misjudged you girls before. You’re not trouble; you’re my lucky stars.”

As he lamented, Caleb’s hands started exploring again, signaling his desire for another round. This time, it wasn’t to gain a new talent, but to ‘repay’ his three enthusiastic female classmates.

Reina and the girls were equally eager, and the four immediately agreed, plunging into battle once more.

Compared to Yukina, who possessed the Physical Vitality talent, Reina and Ruri quickly became unable to continue.

Two hours later, an exhausted Caleb embraced the equally spent Yukina Sasaki and fell asleep.

The next morning.

Sunlight slanted through the window, illuminating the pink walls.

Caleb slowly opened his eyes to the sensation of a delicate, lingering lick below. He gradually recalled everything that had happened yesterday.

Suppressing the pleasure, he opened his personal panel.

[Name: Caleb Uesugi] $star$

[Talent: Physical Vitality, Eye of Insight, Mental Resistance]

[Skill: Basic Mana Extraction]

It was real! It was all real!

Not only had he gained three talents, but the subsequent deep intimacy had surprisingly granted him a skill.

A smile crept onto his lips, and Caleb began to actively cooperate with the three insatiable kittens.

It definitely wasn’t because he couldn’t control himself; he just wanted to see if he could acquire a few more skills or talents.

Unfortunately, Yukina and the girls seemed to possess only one talent each, and the only skill appeared to be Basic Mana Extraction.

He worked hard for a long time, but until his stomach growled loudly, he gained nothing except completely depleting his accumulated reserves.

Having not eaten for nearly sixteen hours, even with the Physical Vitality talent, Caleb was reaching his limit. After all, it was one versus three, and one of them, Yukina, was an equally formidable fighter.

“Are we going to afternoon classes?”

“Let’s take a sick day. I literally can’t move.”

“Ruri, do you have any food at home? I’m starving.”

Hearing the three girls chatting among themselves, Caleb couldn’t help but interject. “Uh… If everything’s okay, I’m going to head out now.”

Yukina exchanged a glance with the other two. Receiving a nod, she spoke. “Uesugi, don’t you have anything else to say?”

“What?”

Caleb looked confused, acting as if he genuinely didn’t know anything.

Reina’s emerald eyes narrowed. “How about you tell us why you kept refusing us before, and then suddenly became so aggressive?”

Caleb gave an innocent expression. “I was forced, wasn’t I? Since it happened anyway, I figured I might as well go with the flow.”

“Is that so?” Reina’s voice was teasing. “Then why did your physical abilities suddenly skyrocket?”

Looking into her beautiful eyes, and remembering the Eye of Insight talent he had gained from her, Caleb’s heart sank.

Bluffing his way out was impossible, but he absolutely couldn’t reveal his true ability. If his secret leaked, not only would it become exponentially harder to ‘cultivate’ with other girls, but he would face much more brutal enemies—enemies far more dangerous than those brought on by the Cuckold-Bait template.
