Inside the room, Lu Xun took another glance at the Ink Shield surrounding him and muttered to himself, "This might be what they call the legendary Rainbow Black."
After a brief study of the defensive level of the Ink Shield and the amount of mana it depleted, Lu Xun felt it was indeed suitable for him.
To others, the mana depletion might be a problem, but to Lu Xun, as long as the Ink Shield is sturdy, usage of mana is irrelevant.
With his massive amount of spiritual power, not to mention a single shield, he could handle multiple at once!
A Russian Doll-type Shield, piece of cake!
After these deductions, Lu Xun pondered a bit and decided to consult his master about why his shield had suddenly turned black, if it could be an issue.
Arriving outside the Small Study, the master was surprisingly still enjoying hot tea in the cold wind.
