บท 387: The Seal of Thunder

While everyone's focus was on the sword "Thunder Blade," Michaux and other top fighters had noticed something else on the stage. It was a web of an unseen force, looming over the stage.

"The Seal of Thunder!" Michaux marveled.

On the stage, a soul-energy seal was slowly taking shape amidst the roiling dark clouds. This was the unique power of the Tactics of the Thunder Blade.

Wang Tong's eyes glinted. He was astonished to see that Lee Xin was able to cast such a powerful spell while engaging in a full-fledged assault at the same time.

Wang Tong always had been very curious about the Mastery's techniques, and had attempted to copy some of their abilities by linking his soul essence with the energy in nature. He conceded that harnessing the nature's energy would be extremely convenient while fighting a large amount of Zergs, since he would not have to worry about exhausting his soul energy in the prolonged battle.
