This kind of instruction essentially brought the teaching scenes from Divine Art Stones into reality. With no time limit, as long as the instructor did not mind the trouble, they could keep teaching until the learner mastered it.
But after one lesson, Mu You had only gained one ten-thousandth of the required comprehension—and that was with a successful attempt. Every attempt had a chance of failure, so actually comprehending Thievery would take at least tens of thousands of attempts. That showed just how difficult Thievery was to learn.
Within a Divine Art Stone's extremely limited time, fully comprehending it might well be impossible.
But with the Pocket Watch to fall back on, Mu You had no such concern. With unlimited Rewinds, he could theoretically master even the most difficult Divine Art in a single session.
Of course, he would not actually do that. Mastering it in one session would be far too shocking. Even a genius had to have limits. Acting so recklessly could easily arouse the other party's suspicions.
So Mu You limited himself to a few hundred Rewinds, raising his comprehension above 1%, then immediately stopped.
``` ["How did it go?" Seeing that you seemed to have finished comprehending it, the Sparrowman Bandit leader looked at you and asked.]
["It worked. I comprehended about 1%," you answered honestly.]
[The Sparrowman Bandit leader looked at you in some shock. He scrutinized your expression, and after confirming that you were not lying, he could not help remarking, "I knew I was right about you. You have the greatest talent of any Sparrowman I have ever met!"]
["At this rate, perhaps you could master all my Thievery in just a few days..." the Sparrowman Bandit leader murmured. His gaze wandered, his expression shifting uncertainly, as though considering something unknown to others.]
