After Shi Feng clicked to use it, the Mastery Book in his hand turned into a streak of silver light and vanished, while a translucent system roulette appeared before him.
A Bronze Mastery Book granted anywhere from 5 to 25 points at random. A player's Luck attribute had no effect whatsoever on this roulette-style randomization.
While the pointer spun, the player could only call for it to stop on their own.
On the roulette, the more Mastery points awarded, the smaller the area they occupied. For example, 5 Mastery points took up 25% of the total area and were very easy to land on, whereas 25 Mastery points occupied less than 1%...
As for relying on eyesight, that was simply impossible.
The pointer spun so quickly that the player's naked eye could not even see it, naturally making it impossible to judge when to stop it.
After Shi Feng called for it to stop, the pointer rapidly slowed.
The pointer stopped at 6 points.
"As expected, getting high Mastery points is really difficult. Fortunately, I have 35 Mastery Books in total. Reaching Advanced Sword Master won't be a problem." Shi Feng could not help but smile bitterly as he looked at the result.
Reaching Intermediate Sword Master required 200 Mastery points, while Advanced Sword Master required 300.
His One-Handed Sword Mastery was currently at 177 points. Adding this time's 6 points brought it to 183, leaving him only 117 points short. With 34 Bronze Mastery Books left, even if every one of them only gave 5 points, he would still gain 170 Mastery points. Advancing to Advanced Sword Master would be no problem. At that time, his One-Handed Sword damage would increase by 50%, raising his combat power by an entire level.
Shi Feng then began using Mastery Books continuously.
