The strength of that innate mosquito, in Zhang Chen's current view, still seems unfathomable.
"That innate mosquito avoided catastrophes within the Underworld, and its strength had infinitely declined, yet it could still battle with that gray-robed man. According to my recollection, its strength should have reached the twelfth tier, if not surpassed it." Zhang Chen murmured to himself.
However, his cultivation at that time was too low, and there was also the Six-Word Mantra restraining the innate mosquito. In retrospect, his view of it at the time was unreliable.
"I should go back and check on my physical body." Zhang Chen worried about his body, fearing it might decay, and quickly returned his Primordial Spirit to the Material Realm.
With his Primordial Spirit returning to the body, blood began to flow through his body, and a glint of brightness appeared in Zhang Chen's eyes: "Not bad! My Blood Sea Dao is indeed extraordinary; my body hasn't decayed yet."
