The difference of a sub-grade in a formation could easily mean a difference in might by twofold, and the difficulty in finding its core would increase exponentially.
Everyone thought that Zhang shi was already formidable to stop a grade-3 primary formation with a single kick, but upon seeing this sight, they finally realized...
Grade-2, grade-3, grade-4, these numbers meant nothing to him!
As long as he was around, even the most formidable formations would be destroyed with a single kick.
Lu Chong's mouth twitched violently, and he shook his head vigorously, as though trying to wake himself up from a dream.
His father had once told him that this formation was unimaginably formidable. His ancestors had reinforced it again and again over the countless generations, and profound wisdom was harnessed within it... But from the looks of it now, wisdom my head! Before his teacher, all of this meant nothing at all.
