The core of the Eight Trigrams Formation is to ensnare. As Pei Xuanjing's realm advanced, his understanding of this sword technique became even more refined. The so-called trap was no longer just a simple, tangible spatial constraint, but also an intangible bondage.
Take this moment, for instance. Even if someone could shatter the spatial command of the Eight Trigrams Formation and grasp the fleeting opportunity to escape during the reformation of shattered space, the power that composed the Eight Trigrams space wouldn't cease to exist. In that instant, the eight forces would fuse with the opponent, entwining them, making it impossible to expel in a short amount of time.
