In contrast, Zhou Heng was able to contend with the Dragon Emperor when he was just a Creation King. Now, having advanced to a Seven Aspects Bright Immortal, his strength has multiplied countless times. Though the power of the Five Elements Rune hasn't improved as drastically, it's still more than tenfold!
One used only a small portion of their power out of disdain, while the other saw a great boost in power and used all they had. If Wang Youyue could still easily withstand it, that would indeed be unreasonable!
However, a Star King is still a Star King. Even with power suppressed to the level of ninety-nine Divine Aspects, it remains terrifying. Zhou Heng, aside from not using the Black Sword, had indeed given his all in that strike, yet he couldn't even make the opponent cough up blood!
His battle with Wang Youyue was, in fact, to use her as a test subject to see if he had any chance of killing the Dragon Emperor with a single blow!
The result was not to his satisfaction.
