With the help of the "Experience Gain" buff, Fang Zheng—no, Airi—quickly completed the system upgrade tests. Overall, there were no problems with acquiring or casting skills. Airi also learned quite a few spells through books and the system tree.
Of course, she did not learn a single one of the Three Unforgivable Curses. In Airi's view, they were completely useless. Avada Kedavra was basically an instant-death spell, and it only worked if it hit. It was also a channeled spell. It had some meaning if two wizards stood still and blasted each other, but if one side ran away, it was utterly worthless.
