More than one...
"But… That was far more exhausting than I expected…" Muttering this to himself as he cast one last glance towards the immortal mushroom before leaving in the direction of the next fragment of the scroll of trials, Xuan Hao felt the clear sense of exhaustion that had appeared after the attack just now.
Although he had only used a single attack, it had by far been the strongest attack he had ever used since breaking through to the Late Stage of the Dao Domain Lord Realm. Having drained quite a bit of his strength.
Thankfully, he didn't really have anyone to fight afterwards, as the immortal mushroom remained in the same place, while the rest of the mushroom monsters in the mushroom forest had at most reached the Domain Lord Realm. Not really posing much of a threat to him.
