Under the nervous gazes of Yuna and Alice, Yang Ling carefully controlled the speed at which he cast the Imprisonment Spell, his massive mental energy seeping into the thin crystal like a thread, closely observing the transformation within.
There was a total of one hundred and twenty eight hand gestures for the Restriction to retrieve things from thin air, and twelve different variations for each gesture. But the Imprisonment Restriction had even more actions to complete. Even though it also only had one hundred and twenty-eight hand gestures, each of the hand gestures had thirty six variations. Luckily, Yang Ling's memory capacity far exceeded that of an average person's. If someone else were to do it, they might not even be able to memorize all of the actions given half a year's time.
