This black breath.
Actually, it had appeared before.
But everyone hadn't taken it seriously.
And now.
When the Black Dragon struck again.
And drew out that breath.
Lu Yuan noticed it and felt it was very familiar.
"This... it seems that I have felt it before at Guang Chengzi's arena."
Suddenly, he remembered that this breath came from the Outer Celestial Demon.
This meant that the Black Dragon in front of him had a significant connection with it; otherwise, how could it emit such a breath?
While Lu Yuan was pondering.
The Black Dragon had no hesitation.
It moved forward directly.
That terrifying black breath spread around it and then surged layer by layer.
Finally, it transformed into an extremely pure force, pouring into the Black Dragon's body.
Buzz, buzz~
Soon.
All of its wounds were completely healed.
Especially the imposing aura that the Black Dragon exuded.
It became even stronger than before.
