Li Jing used her most powerful immobilizing spell, and usually, the stronger the spell, the greater the backlash the user would receive if it failed.
Li Jing already fell unconscious the moment when her spell was failed to bind Instructor Mei Lan, and she even assaulted by a powerful sound attack that made her condition worsened.
Just like yesterday, only Tang Li Xue and Hei Yinghao could still stand up and continue to fight.
Hei Yinghao has a tough body. All of his divine abilities were specialized for close combat battle so it increased his tenaciousness. The damage he received from Instructor Mei Lan's attack was also the least among everyone.
As for Tang Li Xue, if she did not activate her [Golden Body] protection at the last moment before the powerful sound attack blasted her away, her condition would probably the same as Huang Hao and Bing Yi now.
