The Mighty Sky Dragon's Mark

The Primordial Diabolical Bull was very powerful.

This had been the evaluation of some powerhouses after the Primordial Diabolical Bull had become a Dark-Grade source beast.

It had an unparalleled body and an extremely strong defense, so when it attacked, it looked like a unique star that had fallen from seventh heaven.

Although many people had believed that this was an exaggeration, as the Primordial Diabolical Bull charged maniacally, their doubts were wiped away.

The sky shattered under the blue dome of the heavens.

Compared to the majestic Primordial Diabolical Bull, the flame dragon that Luo Yunyang had formed seemed kind of tiny.

Although Old Tie and countless other soldiers were standing on solid ground, their bodies were swaying and toppling. Some of them couldn't even support themselves anymore, so they ended up crashing to the ground.
