Ling Han didn't immediately use Ice Dragon Ground Blast Formation, mainly because he wanted to improve himself using a Shattering Void Tier elite. He always felt that his cultivation improved too fast, for he was eating honestly too much high-level medicinal pills and all sorts of worldly treasures, which settled in his body, and if he didn't stimulate and refine it, it would actually bring about the opposite effect.
Taking two heavy consecutive hits and even resisisting a Shattering Void Tier's martial intent, he already felt the medicinal power that settled in his body slowly being set off and quickly converting into his own Origin Power.
More of the medicinal power nourished his flesh, improving his brute force, an extremely soothing thing.
