The Ten-eyed Great Demon unleashed limitless power, perhaps because its upper limit was too high, or perhaps because there hadn't been enough time to harmonize it, Lu Bei had yet to find the skill bar for the Ten-eyed Great Demon.
Unlike the Great Demon Immortal, which had grown more comfortable with use, especially the initial move of Buddha Country in his palm. He felt that with a bit more practice, it could be added to his own skills bar.
Yet even so, it could not change the Ten-eyed Great Demon's standing in Lu Bei's heart. As the first stage of the double transformation, the Ten-eyed Great Demon was brutishly assertive, capable of overpowering anyone, deploying ultimate skills with just a plain hit, making the presence or absence of a skill bar irrelevant.
Boom Boom Boom!!!
