I added mushrooms for you.

[Have you become more learned today?]
[Accounting for the capacity of your brain, your study efficiency has been increased to 28 times that of normal.]
[The remaining amount of energy you have for studying today, 26 hours.]
[You will enter an exhausted state when your energy is depleted and be unable to obtain new information.]
[Please relax by using the functions within the system and restore your energy as soon as possible.]
With limited energy and the onset of fatigue, the Study Monster had no time to think too much.
Had the heavens not grant me this system, the unending sea of knowledge would seem like a long night.

That meant that he could recover 40 hours of energy in one sitting, then wait for the next month before shopping again.

The efficiency of this activity was rather alluring.
