A low dragon's roar rang out again.
Zhang Yangzi spread his arms and collided head-on with Wang Jinxi.
Their chests pressed together, and their soul power surged out almost simultaneously.
The black wings behind Zhang Yangzi unfurled. A phantom Dark Phantom Demon Eagle rose behind him, and broad swaths of shadow spread from his shoulders and back toward Wang Jinxi.
A dense series of bone-cracking sounds came from Wang Jinxi.
The Bone Dragon King Martial Soul fully possessed his body. Thick, bony joints bulged from his arms and shoulders, and a cold, heavy Dragon-Type aura spread outward.
In the past, as soon as the two powers touched, they would naturally draw each other in.
Zhang Yangzi's darkness and flight attributes would merge into the Bone Dragon King, while Wang Jinxi's strength and defense would support the Dark Phantom Demon Eagle in return.
The two martial souls, which were not a perfect match, would force a point of convergence within their shared soul power frequency.
That was the Dark Eagle Dragon.
Even as an incomplete martial soul fusion skill, it had always been their most important trump card.
But this time, there was no fusion.
The moment Zhang Yangzi's dark soul power touched Wang Jinxi's body, a powerful repulsion erupted from within Wang Jinxi.
It was not Wang Jinxi deliberately resisting.
It was more as though the Bone Dragon King Martial Soul had suddenly gained judgment of its own.
After sensing the Dark Phantom Demon Eagle's aura, it did not accept it as it had before. Instead, it released a low dragon's roar, and a faint gleam of dark gold flashed deep within its joints.
Zhang Yangzi's soul power was forcibly pushed away.
Bang!
Both their bodies jolted at once.
Zhang Yangzi staggered back several steps before landing on his backside.
