"Is this the Energy Potion you mentioned earlier?"
Zheng Qing felt he had finally caught up with the lesson.
"Not exactly."
The professor casually leafed through the handout in front of the Black Cat and pointed to a term as he explained, "Clone Transformation gives wizards a good rest in a short time because it is essentially a forced, rapid means of entering deep sleep... For wizards at the Primary Assimilation stage, this method of 'dream isolation' and 'binary switching' is already enough to restore their energy quickly. In a sense, it wouldn't be wrong to treat it as an Energy Potion.
"But for wizards at the intermediate synchronization stage and above, the sense of rest gained solely through binary switching cannot fully meet their needs. The real Energy Potion is actually hidden inside these avatars of yours."
As he spoke, the professor tapped the Black Gemstone Cat on the head with his pipe.
It rang with a series of clinks.
The Black Cat raised his paws and clutched his head, his eyes brimming with tears, feeling he had suffered for no reason at all.
"—Once they reach the intermediate synchronization stage, wizards can begin trying to control their avatars while their original bodies are awake. However, factors such as mental strength and proficiency in control prevent the avatars from performing highly complex activities. Sleeping therefore becomes the best option for avatars at this stage.
"This way, the avatar rests while the original body goes about its normal activities. When the original body grows tired, the wizard dispels Clone Transformation, and the energy gained through the avatar's rest flows steadily back into the original body. In fact, even at the Primary Assimilation stage, some particularly perceptive wizards can sense a slight restoration of energy from their avatars."
