After accepting the task, Gu Yang, according to the requirements, heads to the Divine Weapon Hall.
Upon entering the Divine Weapon Hall, following the instructions, he returned the silver armor and spirit sword he obtained previously. Then, he swapped them for gold armor and a gold sword.
Both of these items were Earth Grade Spirit Treasures.
Even though they were both classified as standard spirit treasures, the Earth Grade Spirit Treasures were extremely valuable. A typical Celestial Being would have a hard time getting their hands on these.
These two items could probably be exchanged for quite a significant number of fragments.
Including the wind-stabilizing pearl, he now had three Earth Grade Spirit Treasures. The Heavenly Court truly was a massive treasure trove.
Next, following the instructions, he ascended to the second floor and received the River Book (fake). Without this item, it would be impossible for him alone to restore the prohibitions within the Heavenly Court.
