It was hardly Lin Yuan's fault for not thinking of it beforehand.
After all, Little Black was an "Artisan," not a "thief."
But Little Black soon sent him a thought, explaining why it could pick locks.
It did not actually have a thief's lockpicking ability, but these boxes and locks had been manufactured by the Artisan Academy itself.
The designs for these locks had originally existed in those Artisans' minds.
Naturally, Little Black had inherited them as part of its instincts.
So its lockpicking ability only worked on the boxes in this Library.
It could not actually serve as a universal lockpick.
Moreover, the locks manufactured by the Artisan Academy certainly were not simple mechanical locks. They all contained trace amounts of special supernatural materials.
Only a key with the correct structure, combined with the corresponding Artisan Power, could open these locks.
At the same time, opening these locks consumed Artisan Power.
That was why the Wandering Faction players kept hunting Administrator Golems everywhere: the Artisan Power contained in a single key was limited.
As such, the number of locks a single key could open was also limited.
And the higher the quality of the box, the more Artisan Power opening it consumed.
So the players' demand for keys was practically endless.
Although Little Black had far more Artisan Power inside it than a key did, its supply was not infinite either. Once depleted, it needed time to slowly recover.
By its own estimate, it could open over 2,000 copper boxes, but only 200 silver boxes. As for the higher-grade gold boxes, it estimated it could open around 20.

After learning all this, Lin Yuan immediately made his decision-
There was no need to
