Above the Black Demon Sect, the ancient mirror appeared behind Mu Qing, revealing the sole reality within the Immortal Starry Sky.
He formed seals with both hands and summoned the Heaven-Opening Banner.
Because Mu Qing's Heaven-Opening Banner divine ability was a simplified version and lacked a powerful sacred artifact as its core, it appeared rather illusory.
The difficulty of the fifth tribulation lay in unleashing one's strongest power to break through those dense earth tribulation clouds.
What was already incomparably difficult for Four-Tribulation Rulers was even harder than climbing to the heavens for final-stage Supremes like them, who had rushed up in one breath.
That was precisely why Wu Xuanyi wanted to explore the burial grounds of the Dragon Domain experts, hoping to find a level-three supreme treasure to help him pass the fifth tribulation.
Mu Qing, on the other hand, had considerable confidence in himself. The Life-and-Death Mirror not only possessed the characteristics of a dharma body, but also contained terrifying destructive power.
Yet at this moment, he had no choice but to admit that the combined divine ability Mo Zi had created was truly astonishing!
That terrifying drain was immensely taxing even for Mu Qing, who possessed the Primordial Cosmos Scripture.
And this was only the simplified version!
At the same time, the Life-and-Death Mirror's consumption was enormous as well. Using these two divine abilities in succession left even Mu Qing feeling incomparably strained.
One was a combined divine ability, a simplified version comparable to a great divine ability, while the other was a divine ability possessing dharma-body characteristics!
Inside the sect master's hall, Mo Zi let out a long sigh, feeling somewhat defeated.
Mu Qing had truly learned it!
Even if it was only the simplified Heaven-Opening Banner, it would have been basically impossible for anyone else
