Zong Yan of the half-step Grotto-heaven realm had already used a trace of Grotto-heaven power when he attacked earlier on.
The True Martial Dao Body was only at lesser mastery and was slightly inferior in terms of strength. That was the reason why the Martial Dao Prime Body was forced to retreat a half-step.
This did not mean that Zong Yan could threaten the Martial Dao Prime Body.
Right now, the Martial Dao Prime Body had just passed the True Martial Heavenly Tribulation and fought against Yan Zui and the others—his trump cards were almost depleted.
If he was in his peak condition, the Martial Dao Prime Body could release his Bloodline Phenomenon and summon the Heaven and Earth Furnace to refine Zong Yan's Grotto-heaven phantom directly!
"Oh?"
