Right from the moment Heaven Star exchanged the Candle Dragon's main material, An Jing knew that the remaining four hundred thousand plus merits he had wouldn't be left in the Pioneer Space to earn interest.
To face the clearly unusual Nirvana Tribulation of the Bright Mirror Sect, he needed to do many things, one of which was exchanging the Heavenly Mirror Shard.
However, unlike the automatic unlocking of all tasks for the exchange of the Candle Dragon's body, exchanging the Heavenly Mirror Shard required completing a mission called [Celestial Domain Scattering].
The question is, what exactly is the Celestial Domain Scattering?
An Jing naturally didn't know, only Cheng Guang Ancient Ancestor, who was aware of the Dao Courtyard's ancient texts left by Visible Empty Ancestral Master during the Ancient Times, vaguely guessed that [Celestial Domain Scattering] was related to the Heaven and Earth Phenomenon that manifested when the Haotian Mirror achieved the Dao.
