During the era of the ancient Heavenly City, there had only been two great masters who were fortunate enough to successfully refine their '33 Divine Beasts' Combined Magical Treasure' before ascending to the Fifth Stage.
Song Shuhang wondered which of those two great masters the heavenly tribulation had decided to copy while creating its version of the combined magical treasure.
In all honesty, he hoped that the 33 kinds of magical treasures could be combined and made into a giant robot as it was every boy's dream to be able to have a giant mecha of their own. This dream was at the same level, if not even higher, compared to man's dream of flying in the sky. After all, the giant mecha would very likely allow one to fly as well—it was a two in one, truly worth having.
Just imagine: while he was dueling, he would take out the 33 kinds of magical treasures, and shout, "Combine!"
