"That's right. You're her son, and it's most fitting for you to go," Rhea's gentle voice enchanted Ross, leaving him speechless. "Yes, I'm her son. I should be the one who finds her," Ross replied, nodding.

Rhea smiled, pleased with her success. "Go to sleep then. You'll depart early tomorrow, okay? Remember that," she stressed. "Okay!" Ross answered, nodding again.

Rhea tapped the bottle, causing it to chime. Ross blinked, then fell soundly asleep.

Rhea left the room and was soon escorted to Fred's office. He awaited her impatiently. Since Ross had insisted on the removal of surveillance devices from his room, Fred had been unable to witness the events firsthand. He looked at Rhea expectantly. "Did it work?"

"Congratulations, Your Grace. You got what you wanted," Rhea said, bowing respectfully.

Fred was elated; he could now control Ross and manipulate others through the drug and Rhea's hypnosis. While he harbored a greater interest in the invisibility potion, he was satisfied with gaining control over specific individuals.

"That's great!" he laughed heartily. "Next, we start mass-producing the drug. Everyone will have to listen to me soon!"

"Well..." Rhea hesitated.

"What is it?" Fred glared. "Speak your mind!"

"Nothing," Rhea shook her head. She wanted to mention the scarcity of raw materials for R10, limiting production. Even mass production would be hampered by supply issues. However, she knew this would displease Fred and undermine her recent success. Instead, she said, "I just wanted to say that the most pressing matter now is sending Prince Ross away."

"Didn't you say the hypnosis worked?" Fred frowned. "Is there a problem?"

"No, he already promised to leave early tomorrow." This was a task Fred had assigned her. Not only had she completed it, but she'd also uncovered unexpected information. The queen's disappearance in Hyderland was significant; she could use it to her advantage against Fred if she played her cards right. However, the time wasn't right, and she needed to maintain her obedience. "That's good," Fred said, relieved. He then posed the question he'd raised earlier. "Can I control others? Must they only listen to you?"
