The Quasi Corpse King was indeed immensely powerful, with the Spiritual Power of a Divine Infant at the Third Layer Heaven combined with the innate brutal strength of a walking corpse, it far surpassed the strength of an average Quasi Heavenly Venerate, and even Zhou Heng found it to be a worthy opponent.
Of course, all this was predicated on the fact that Zhou Heng had not yet employed the powers of the deities.
The physical strength of the walking corpse was equivalent to that of deities, and the Quasi Corpse King had pushed its own strength to the limit, yet Zhou Heng had only used his Spiritual Power, the disparity between them clear at a glance.
Zhou Heng let out a long howl, and the skies were set ablaze with undulating purple flames, as he began his forceful counterattack.
