Heng Feng already had a battle plan in mind before Duan Ling Tian arrived. Drawing from his previous mistakes and experience, he cast the law of earth's Rock Style Profundity, Crystal Barrier Profundity, and Defense Profundity. After he cast the Crystal Barrier Profundity, what seemed like crystal armor appeared on his body. At the same time, his Celestial Origin Energy that had been boosted by the Earth Elemental Profundity had reached its peak, and he could easily cast another three profundities from the law of earth at a moment's notice. Apart from the three profundities he had just cast and the Earth Elemental Profundity, he had comprehended the Shake Profundity, the Gravitational Space Profundity, and the Recovery Profundity as well.
