Chapitre 337: The special zone

Yang Qing sighed in admiration as he observed the passed-out Zou Liqin. Her passing through the four cardinal ten trigram formation was worthy of his recognition.

The formation was a top-tier blue-grade formation which meant it could draw the energy of the dao of heaven and earth to create a sense of spirituality when it was activated. It could entrap and kill anyone at the palace realm and below, and if an early-stage domain expert was caught off guard, suffering heavy injuries was not an impossibility.

Yang Qing decided to use a miniature version of it since the original version required an ascendant-grade material and several top-tier monarch-grade treasures as materials to lay it down. 

If he dared use such high-grade materials for a test that had a late-stage qi refinement expert as the peak expert, he had no doubt he would end up charged with over a dozen of fines for misappropriation of resources.
