Reincarnated With Three Unique Skills

As she began the otherworldly process of crafting the Energy Converter inside Aengus\' body, he watched with rapt attention, absorbing every detail in an attempt to learn as much as possible. The process was intricate, the materials blending together in ways that defied normal understanding.

After completing some initial modifications, MANAS paused, awaiting his permission. Once Aengus granted it, she took full control of his body, her demeanor becoming more focused and precise. "Universal Synthesis," she commanded, her tone authoritative, "synthesize these materials according to the specific data model and create an Internal Energy Converter."

Aengus observed in awe as MANAS communicated with his skills, issuing precise commands to create the converter according to the blueprint stored in her mind. The process was both fascinating and complex, involving the integration of the Void Stone\'s energy absorbing properties, the etherium dust\'s energy-conducting abilities, and the unparalleled potency of the dragon\'s blood.

Slowly but surely, the materials began to merge, forming a cohesive structure within Anegus\'s body. The Energy Converter started to take shape, its design optimized to channel and convert raw energy into a form Ethan could use. MANAS worked tirelessly, her every action guided by the blueprint she had crafted, ensuring that the final product would meet Ethan\'s exact specifications and needs.

As the process neared completion, Aengus felt a surge of Mana within him, a sign that the energy converter was beginning to function. MANAS, still in control, made final adjustments, fine-tuning the converter to ensure it operated at peak efficiency.

With a final command, the synthesis process was complete, and the Internal Energy Converter was successfully integrated into Ethan\'s energy storage, between Mana pool and Nether Energy core. It was interconnectedly attached with extraordinary craftsmanship.

He could now Nether Energy into Mana and vice versa

"Master, the Energy Converter is now operational," MANAS reported, her voice filled with satisfaction. "You should be able to access and manipulate energy more efficiently than ever before."

Aengus took a deep breath, feeling the steady pulse of power within him as he regained control of his body. "Thank you, MANAS. Now we can finally start with our plan."

"Yes, Master," MANAS replied, her voice clear in his mind. "Now I can communicate with you always. But first, you need to gather those Demon cores."

"True..." Aengus agreed, pulling out the last 100 low-grade demon cores he had. He added a few more from the baron\'s treasury that he had kept for himself.

With a focused mind, he began synthesizing the cores, merging two low-grade cores into one middle-grade core. The mid-grade cores were far more potent, each containing the demonic essence of five low-grade cores. When the process was complete, Aengus had 50 mid-grade cores in hand, their dark energy resonating in his palm.

Satisfied, Aengus called out for his butler, a man who had once been a mere shadow to him but had since come under his influence through the use of Darkness Haki. Aengus was confident now that Butler Yu won\'t betray him.

Butler Yu entered the room silently, bowing with practiced respect. "Lord, you need something?" he asked, his voice calm, though his eyes gleamed with newfound reverence.

Aengus, seated at his desk, gestured to the high-grade cores laid out before him. "Quickly, exchange these mif-grade cores for low-grade ones, but do so discreetly. Ensure that no one notices or becomes suspicious."

"Yes, my lord," Butler Yu responded with a deep bow. He carefully gathered the high-mid cores and left the room without another word.. Though curiosity gnawed at him, he knew better than to question his master\'s orders. His sole focus was to fulfill Aengus\'s command without drawing unwanted attention.

As Butler Yu made his way to the market nearby, Aengus leaned back in his chair, and waited back for butler Yu\'s return.

Aengus checked his stats, noting with satisfaction that all of his Nether Energy had already been converted to Mana. However, he realized he still needed more demon cores to completely fill his reserves—or perhaps even upgrade them further.

After a while, Butler Yu returned, carrying 250 low-grade demon cores, as instructed. Without hesitation, Aengus began the synthesis process again, transforming the cores into 65 high-grade ones, which were equivalent to 650 low-grade cores.

Once again, Aengus handed the high-grade cores to Butler Yu for exchange. This time, Butler Yu\'s heart pounded with fear as he realized the incredible ability his new master possessed. But he knew he must not let anyone discover this secret.

Thanks to Butler Yu\'s hard work and caution, Aengus managed to gather more than 15,000 low-grade cores within 12 hours. The sheer quantity was astounding, and Aengus knew he was getting closer to achieving his goals.

"Here... take this for your hard work, Butler Yu," Aengus said, offering him 100 low-grade cores as a reward.

Butler Yu hurriedly declined, bowing deeply. "No, my lord, it was my duty as your humble servant. How can I accept such a gift from you?" His voice was sincere, reflecting the loyalty he felt deep within.

"It\'s fine... Take it. It\'s an order. If you wish to stay by my side and become one of my most trusted subordinates, you should do as I say," Aengus said firmly, his tone leaving no room for argument.

"Then, I will not refuse, my lord. This humble servant will be your shadow and sword," Butler Yu replied, bowing again as he accepted the low-grade cores. With a final nod, he left the room to carry out his duties.

Aengus turned his attention back to the task at hand. He synthesized the cores once more, but this time, he consumed them, feeling the power surge through him. The synthesis resulted in nearly 4,000 high-grade cores, equivalent to 40,000 low-grade cores. However, Aengus knew he couldn\'t continue at this pace without drawing attention.

He would need to build a specialized army for such tasks in the future.

As he consumed the cores, Aengus felt his physical stats rise:

[Strength +2]

[Defense: +3]

[Agility +2.5]

Most importantly, he could feel the essence of the cores converting into pure Nether Energy more:

[Nether Energy +10]

[Nether Energy +12]

[Nether Energy +9]

...

The surge of power was intoxicating, and Aengus knew he was becoming stronger with each passing moment.
