“WHAT?!!!” Reina Hamasaki was now wide awake. She was about to ask Caleb what on earth he was thinking, only to find that the call had ended.

“Ugh!” Annoyed, Reina Hamasaki ran her hands through her smooth blonde hair, turning it into a bird’s nest. She picked up her phone and dialed Yukina Sasaki’s number…

Caleb put down his phone, quietly calculating in his mind. He called the four girls over, not because the Takamine sisters hadn’t satisfied him. Earlier this afternoon, he clearly felt extremely mentally fatigued. Unexpectedly, after making love with the Takamine sisters, he not only wasn’t tired but felt his vitality and spirit had improved.

He initially thought it was the effect of the Devil Bloodline reinforcement. But upon careful reflection, he realized the key wasn’t the Devil Bloodline, but the exchange of bodily fluids itself.

The first time Rias entered him with the Evil Pieces, Caleb felt his body weaken, his spirit fatigue, and his magic power diminish considerably. After his subsequent intimacy with Tsubaki Shinra, he felt much better, essentially no longer feeling drained. At the time, Caleb hadn’t thought much of it, assuming that acquiring the Devil Bloodline had reinforced his body, mind, and magic power all at once.

However, he later realized that the Devil Bloodline’s effect was a gradual process and required a massive energy supplement. In fact, the Devil Bloodline hadn’t fully integrated even now.

Subsequently, to avoid exposure, Caleb let Sona Shitori enter him with the Evil Pieces more than ten times. This time, likely annoyed by the constant penetration, his body’s rejection was stronger, which resulted in him becoming even weaker. Caleb suspected that if he underwent reincarnation again, the Evil Pieces wouldn’t even have a chance to merge. If the Evil Pieces were likened to a virus, that rejection was the immune system. After two viral invasions, the immune system had recorded the situation and would immediately isolate the virus upon first detection next time.

Returning home, after a massive food supplement, the Devil Bloodline began to take effect. Caleb felt his body and magic power improving rapidly. But the mental fatigue hadn’t lessened at all. It wasn’t until he messed around with the Takamine sisters in the bathroom that his vitality and spirit gradually began to recover. After the second battle in the master bedroom, Caleb was fully restored.

With the enhanced perception granted by the Devil Bloodline, he finally grasped the key. The Takamine sisters were exhausted and couldn’t continue the conquest, and he was eager to verify his theory. That’s why he called the four girls—Reina Hamasaki, Yukina Sasaki, Ruri Kurumizaka, and Yuuki Shinamura—over for a late-night orgy.

As for being rejected… Caleb thought there was a 99% chance it wouldn’t happen… to be conservative, 90% chance of not being rejected. If his judgment was correct, the Hamasaki group would definitely come.

At 1:00 AM, a knock sounded at the Takamine residence door. Caleb’s face showed excitement. His enhanced hearing clearly distinguished four sets of footsteps. Reina Hamasaki, Yukina Sasaki, Ruri Kurumizaka, and Yuuki Shinamura had all come.

Amidst the four girls’ resentful or curious gazes, Caleb led them into the living room.

“Uesugi, why isn’t the light on?” Yukina Sasaki frowned. She didn’t like dark environments.

“Not on?” Caleb quickly realized that due to the Devil Bloodline’s night vision, any sliver of light made it indistinguishable from daytime for him. Of course, this didn’t mean a Devil couldn’t tell the difference between day and night. It was just that Caleb had just acquired the ability and hadn’t fully adapted yet.

“I forgot. You guys turn it on.” Caleb reached out and put his arm around Reina Hamasaki. “You told them, right? Let’s start now.”

Reina Hamasaki twisted her hips, huffing angrily. “I told them, but aren’t you going to explain yourself?”

Caleb deliberately put on a look of ignorance. “Explain what? I felt like doing it, so I called you over.”

Yuuki Shinamura was the first to protest. “Hey, what do you take us for? And don’t you have two women at home?”

“Yeah, yeah~” Ruri Kurumizaka chimed in. “You haven’t paid attention to us recently, rushing off to find Rias-senpai every time you had a moment.”

“Didn’t I tell you? I was learning some knowledge about the other world.” Caleb began to undo Reina Hamasaki’s clothes, smiling. “Now I’ve learned quite a bit, so I have time for you.”

“What did you learn?”

Caleb started taking off his own clothes. “A lot. Besides general knowledge, I learned close combat and magic.” He added, “I won’t lie to you. The four of you together are no match for me now.”

Among the four girls, Yukina Sasaki had the highest combat power, roughly on par with Tetsuya Oda’s first transformation stage. When Tetsuya Oda activated his Berserker mode, he could beat all four of them easily. And Caleb could now thoroughly beat the Berserker-mode Tetsuya Oda.

“Seriously?” Yuuki Shinamura was the first to disbelieve. Caleb’s ability to ‘counter-kill’ her in three days could barely be explained by bloodline awakening. Now, after such a short time, his strength had made another leap? Is this scumbag actually a genius? Impossible, absolutely impossible. He went to the Occult Research Club just for Rias’s beauty! It must be!

Caleb rolled his eyes at her, too lazy to deal with the little blonde. He’d deal with her properly later, letting her know what Enchantment was!

In the span of a few sentences, Caleb and Reina Hamasaki were already in position.

“Mmmph~ Aren’t you even more eager than me?” Little Caleb was poised on the muddy path. Without needing to exert himself, Reina Hamasaki actively lifted her waist and swallowed him whole. After over a week, the sudden entry made Caleb sigh in comfort.

“And you were demanding an explanation…”

Reina Hamasaki’s face was flushed, and she stayed silent, cupping Caleb’s face with her hands and kissing him. Her hot lips sealed Caleb’s words. They had been pent up for over a week. After experiencing Little Caleb, fingers and scissoring felt inadequate. But they didn’t want to find other men. They resisted the thought completely.

They knew it had to be related to Caleb’s unique constitution, just like how intimacy could enhance their strength… It was easy to get on the boat but hard to get off. For now, they couldn’t and didn’t want to solve the problem. Caleb was powerful and handsome, satisfying their desires while also boosting their strength. Emotionally, it wasn’t love, but there was certainly some affection. Even if there hadn’t been originally, daily interactions over time had fostered it.

The only thing they had to be careful about was preventing Caleb from knowing this. Otherwise, Caleb would have an easier time controlling them. They were excellent at keeping secrets, and Caleb had been completely fooled until now.

If he hadn’t gained the Devil Bloodline today, sensed the abnormality during fluid exchange, and connected it to his ability’s name and the afternoon’s events, he might never have figured it out. When he first awakened his ability, Caleb had wondered why it wasn’t called the Talent Copying Ability. That name clearly fit the ability’s effect better.

Dual Cultivation, as the name implied, meant both parties benefited. Otherwise, it should be called Energy Harvesting. Furthermore, copying talents didn’t have anything to do with the word ‘Cultivation.’

What if the Dual Cultivation ability also supplemented both parties’ vitality and spirit through mucosal contact…? Simply put, it filled whatever was lacking. Once full, it then enhanced attributes like magic power, mental strength, and physical fitness.

If the Dual Cultivation ability had this effect, then everything would fall into place. Including why the Hamasaki group had been relentlessly pursuing him. In all likelihood, it was because Reina Hamasaki had discovered his special constitution.

Caleb often used his Eyes of Insight and found the ability incredibly useful. Especially when combined with magic power, it gave him a sense of having Fiery Golden Eyes.

…

Half an hour later, Reina Hamasaki’s body stiffened, and her crystal-clear toes curled tightly. Caleb no longer held back. After a tingly sensation in his lower back, he slowly withdrew. He smoothly brought her long, beautiful legs together, preventing the white fluid from flowing out, and looked at the three girls beside them whose breathing was quick and shallow.

“Who’s next?”

“Hehe, then Ruri won’t be shy.” Despite her initial complaints, Ruri Kurumizaka’s body was honest.

After dealing with Ruri Kurumizaka, Caleb ignored Yuuki Shinamura’s pathetic, longing gaze and lifted one of Yukina Sasaki’s long legs, starting the third round in a standing, face-to-face position. Yukina Sasaki had the best physical fitness and the best compatibility with Little Caleb. After a standing round, Caleb couldn’t resist pinning Yukina Sasaki to the floor and taking another round while holding up her pale, long legs.

Seeing that if she didn’t speak up soon, Caleb would go back to Reina Hamasaki, Yuuki Shinamura blushed, pushed Caleb down, and flipped to ride him.

“Tsk, tsk, didn’t you say…” Caleb was about to mock her, but seeing her on the verge of tears, he swallowed his words. Teasing a Tsundere was certainly fun, but going too far could hurt their feelings.
