Rhea would control everything and possibly threaten Fred if necessary.

"Not yet," Rhea said, looking troubled. "I understand your concerns, but R20 only works in conjunction with hypnosis, which requires time to master. We must establish a foundation and provide specific commands for hypnotic suggestion, especially initially." Flicking the wine bottle, for instance, was a subtle suggestion to Ross, conditioning him to the hypnotic influence.

"Enough!" Fred interrupted impatiently, raising a hand. "Just hearing that gives me a headache. Remember, you must still obey me, even with your expanded abilities. Is that clear?"

"Yes, Your Grace," Rhea replied, lowering her head.

However, Fred did not fully trust her. In fact, he rarely trusted anyone completely. The queen served as a cautionary example; she had trusted him, only to be betrayed. This experience shaped his deep-seated skepticism.

"Never attempt to use R20 on me. You are in my power and cannot escape the consequences. Even if you were to control me, you cannot manipulate all of Yudonia. Obey me, however, and I will reward you when I rule the world."

Rhea, shocked, glanced at him and nodded. "I will not disobey you, Your Grace."

She had never anticipated Fred's ambition to rule the world. Her own aspirations centered on advancing civilization through her research, not global domination. She knew unleashing chaos was simple; controlling it presented an insurmountable challenge. She mused, How can he control such a vast territory and its people? Her primary concern was fame, even notoriety.

"You've done well today. Get some rest, and continue working on the invisibility potion tomorrow. Its development is paramount," Fred commanded sternly.

"Yes, Your Grace," Rhea replied, leaving. Privately, she found Fred even more unreasonable than her previous employer; at least the latter understood limitations. The duke, however, demanded the impossible. She feared he would abandon her if she failed to meet his expectations.

Returning to her room, Rhea lay down, pondering the events of the past two days. A sense of unease settled upon her, though she couldn't quite articulate its source.

When Fred had inquired about someone's sudden death, she had only been able to hazard a guess. Reflecting now, she suspected he had been referring to Lily. Yet, she found that unlikely. Lily has been fine, hasn't she? Confined to the embassy, she lacks access to any drugs that would simulate a fatal illness. It doesn't seem plausible.

She couldn't resolve the puzzle. However, she knew Fred would seek her help if Lily was indeed involved.
