The Boundless Infinitum Set, also known as the world's best legendary armor suit. Of course the true god set — the only god set — had its claim to fame.
The Heavenly Snow Mountain and the Heaven's Expanse Palace had been each other's rival for such a long time. If Xue Ao'tian really had the power to kill Shangguan Tianyang, he would have done so earlier a few tournaments back. How could he possibly show any mercy to him? However, he was unable to do it, and the reason was none other than the Boundless Infinitum Set that Shangguan Tianyang owned.
An eight-piece legendary armor set could hardly scratch the 'legendary' title but a nine or ten-piece set was definitely a legendary set. As for an eleven-piece armor set, well, it would no longer be limited by the word 'legendary'. Instead, it would be a true god set.
