"The Training of Soldiers, requires 80 points for access, may not be taken out of White Tower!"
"Wanderer Advancement, requires 200 points for access, may not be taken out of White Tower!"

There's a scheme to the transcendent books in the White Tower: higher tiers are found on higher levels, and high-tier content is not found on lower levels.
With just a flip through the third level, Su Lu had found the career information for [Soldier] and [Wanderer]. Seeing the appalling expense, he couldn't help but wince.
"It would be great if you could simply touch them to gain the career information. Unfortunately, that's not a feature."
Despite the power of the attribute interface, it still required him—the host—to read first in order to activate it.
Without advantage in this aspect, Su Lu could only borrow "The Training of Soldiers" first and read through it slowly.
