An Jing's heart was racing as the secret technique "Nine Tribulations Ascension" rapidly spun into action.
The so-called Tribulation directly stemmed from the Heavenly Dao, a feedback from the world itself.
This feedback could be punishment, encouragement, or even a Heavenly Revelation. In essence, it was unchanging in its attribute: [Originating from Heaven, reaching directly to the Dao].
Within a Heavenly Tribulation, lies the fundamental essence of the operation of the Heavenly Dao, which itself encompasses the vastness of the Heaven and Earth Dao, providing a rare channel for direct 'communication' with its supporters and challengers.
To put it simply, it's like the illusive will of Heaven and Earth, which under normal circumstances would absolutely have no contact with humans.
Unless It truly materialized a giant palm and delivered a slap.
